Description

The present invention relates to an auxiliary power supply device for lighting fixtures and lighting fixtures used in ordinary homes.

Lighting fixtures such as ceiling lights are widely used in ordinary homes. When installing these lighting fixtures on the ceiling (mounting part), it is common to first attach a lighting installation adapter designed specifically for lighting fixtures to the power supply unit of a ceiling hook or other fixture installed on the ceiling (mounting part), and then attach the lighting fixture body to this lighting installation adapter. By using the power supply unit and lighting installation adapter in this way, the lighting fixture body can be installed on the ceiling (mounting part) with simple operations. The lighting installation adapter is mechanically and electrically connected to the power supply unit that receives AC power from a commercial power source, and it holds the lighting fixture body and also serves to supply AC power to the lighting fixture body via the lighting installation adapter.

The power supply unit of a ceiling hook used in lighting fixtures such as ceiling lights is a dedicated outlet for the lighting fixture. Therefore, efficient use of AC power has been proposed, such as branching off a portion of the AC power supplied from this power supply unit and supplying it to other lighting fixtures (see, for example, Patent Document 1).

In a typical home, a power supply unit called a hook-on ceiling rosette, hook-on ceiling body, hook-on ceiling, hook-on rosette, etc. is attached to the ceiling for mounting a ceiling light, etc. As shown in Figures 6(A) and (B) , a lighting fixture is attached to a power supply unit 1 installed on the ceiling (mounting portion) 18 inside the home.

In addition, AC power is supplied from a commercial power source to a general household dwelling. The power supply unit 1 and the lighting mounting adapter 10 are mechanically and electrically connected by attaching the lighting mounting adapter 10 to the power supply unit 1 installed on the ceiling (mounting portion) 18. By connecting the power supply unit 1 and the lighting mounting adapter 10, AC power is supplied to the lighting mounting adapter 10 from the power line in the house through the power supply unit 1.

Here, an auxiliary power supply device for a lighting fixture according to an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below shows one specific example of the present invention, and therefore the arrangement, functions, numerical values, etc. of the components described in the embodiment are merely examples, and the scope of the present invention should not be interpreted as being limited by these.
(Embodiment 1)
Hereinafter, an auxiliary power supply device for a lighting fixture according to a first embodiment of the present invention will be described with reference to the drawings.
First, the configuration of the lighting mounting adapter 10 will be described. Fig. 1 shows a schematic cross-sectional view of the lighting mounting adapter 10. The figure illustrates the lighting mounting adapter 10 functioning as an auxiliary power supply for a lighting fixture. A DC power supply unit 20 is housed in the lighting mounting adapter 10. Note that in Fig. 1, components such as a hook bracket 15, DC power supply unit 20, and DC power output terminal 30 are depicted as schematic cross-sectional views, with hatching representing cross sections and internal structures omitted.

The lighting mounting adapter 10 has a top plate 12 at the top, a bottom plate 13 at the bottom, and side plates 14 on the sides, and is generally cylindrical in shape. The top plate 12 and bottom plate 13 are generally circular flat plates, and a pair of hook-shaped hook fittings 15 are fixed to the top of the top plate 12. The hook fittings 15 are fixed in such a way that the hook-shaped parts of the hook fittings 15 fit into two arc-shaped locking grooves (hook fitting locking grooves) drilled in the power supply unit 1 (mounting unit) installed on the ceiling (mounting unit) 18. This fixes the lighting mounting adapter 10 to the power supply unit 1, and electrically and mechanically connects the hook-shaped parts of the hook fittings 15 to the output terminals in the power supply unit 1, thereby conducting AC power.

The lighting mounting adaptor 10 also has a pair of claws 16 that protrude from not-shown notches drilled in the side plate 14. The claws 16 are biased toward the outside of the side plate 14 of the lighting mounting adaptor 1. The top plate 81 of the lighting fixture body 80 also has a substantially circular opening 84.

To attach the lighting fixture body 80 to the lighting mounting adaptor 10, the opening 84 in the top plate 81 is inserted into the lighting mounting adaptor 10. Next, when the top plate 81 is lifted up so as to push the tab 16, the tab 16 is pushed into the side plate 14. The top plate 81 climbs over the tab 16, and the tab 16 is positioned below the top plate 81. As the tab 16 is biased toward the outside of the side plate 14, it protrudes toward the outside of the side plate 14 again, supporting the top plate 81 from below.

To remove the top plate 12 from the lighting mounting adaptor 10, a pair of release levers 17 provided on the bottom plate 13 of the lighting mounting adaptor 10 are used (the claws 16 and the release levers 17 are collectively referred to as the holding members). By placing hands on the pair of release levers 17 and moving them inward, the claws 16 retract into the side plates 14, the lock of the top plate 12 is released, and the top plate 12 is removed from the lighting mounting adaptor 10.
The shape of the lighting mounting adapter 10 is not limited to a substantially cylindrical shape, and various shapes such as a rectangular parallelepiped, a triangular prism, or an octagonal prism may be adopted.

The lighting mounting adapter 10 includes an AC power output cable 19 that transmits AC power supplied from the power supply unit 1, and an AC power output cable 40 that connects to the AC power output cable 19 and outputs AC power to the outside of the housing 11. An AC power output terminal 41 is attached to the tip of the AC power output cable 40. The AC power output terminal 41 connects to an input terminal (not shown) provided on the lighting fixture body 80 and supplies AC power to the lighting fixture body 80. The AC power output cable 40 may be branched to include multiple AC power output terminals 41. The AC power output terminal 41 may also be installed on the bottom plate 13 of the housing 11 so as to be parallel to the DC power output terminal 30 described below.

The housing 11 of the lighting mounting adapter 10 also contains a DC power supply 20 that connects to an AC power output cable 19. The AC power input to the DC power supply 20 is converted to DC power and transmitted to the DC power output terminal 30 through the DC power output cable 21. For example, an AC voltage of 100V is converted to DC 5V. An external electrical device with a matching output voltage is connected to the DC power output terminal 30. The DC power output terminal 30 is usually installed on the bottom plate 13 of the housing 11 so that its tip is approximately flush with the bottom plate 13 and does not protrude from the bottom plate 13. As shown in FIG. 2, the DC power output cable 21 may be configured to extend from the bottom plate 13 of the housing 11.

The DC power output terminal 30 is a USB (Universal Serial Bus) terminal or the like. If necessary, the DC power output terminal 30 can be provided at a plurality of locations, such as two locations, by branching the DC power output cable 21. Furthermore, a DC power socket or other power terminals may be provided.
In use, the DC power output terminal 30 is connected to a USB input terminal of the external electric device 100 by a USB cable. Through this connection, the DC power output from the DC power supply device 20 is received by the external electric device 100.

The external electrical device 100 may be, for example, a lighting device having a function different from that of the lighting device main body 80 (e.g., a spotlight, an emergency light), various sensors (e.g., an illuminance sensor for measuring the brightness of the room, a human presence sensor for detecting the presence or absence of a person in the room, a temperature sensor for detecting the indoor temperature, humidity, and other conditions), a camera (e.g., a surveillance camera, an infrared camera, a video camera), audio equipment (e.g., a speaker system, a microphone, a radio), an infrared communication device (e.g., an infrared signal transmitting and receiving device for transmitting and receiving infrared signals to the lighting device main body 80 or an external electrical device), a video device (e.g., a projection device for projecting characters, symbols, images, and messages onto a screen including the lighting cover 90, a television receiver, an electronic bulletin board), a mobile communication device (e.g., a third generation mobile communication system (3G), a fifth generation mobile communication system (5G), LTE (Long Term Evolution) communication, LPWA (Low Power, Wide Area) These include communication devices using Bluetooth (Bluetooth Area) communication), wireless communication devices (e.g., Wi-Fi (registered trademark) wireless communication devices, Bluetooth (registered trademark) transceivers, wireless communication repeaters), or systems that combine the above types of devices.

A relatively light-weight external electrical device 100 can be attached to the lighting mounting adapter 10 by inserting it into the DC power output terminal 30, by bonding with double-sided tape or adhesive, or by a magnet if the bottom plate 13 is made of a metal material such as iron. Furthermore, a heavier external electrical device 100 can be attached by any suitable fixing means, such as by screwing it to the bottom plate 13 of the housing 11 or by attaching it to a mounting attachment fixed to the housing 11.

6(A) and (B), the configuration of the lighting fixture body 80 will be described. The lighting fixture body 80 is attached to the power supply unit 1 using the lighting installation adapter 10. The top plate 81 of the lighting fixture body 80 is a flat plate made of metal or the like, has an opening 84 in the center, and is generally ring-shaped. As described above, the claws 16 of the lighting installation adapter 10 act to support the periphery of the opening 84 of the top plate 81 from below. As a result, the lighting fixture body 80 including the top plate 81 is held by the claws 16 so that it does not fall off the lighting installation adapter 10. A light source 82 consisting of a board on which light-emitting elements such as LEDs are mounted, and a control unit 83 are arranged under the top plate 81. The control unit 83 is equipped with a light-receiving unit 85 of the remote controller 91, a drive circuit (not shown), and the like. Note that the light source 82, the control unit 83, the light-receiving unit 85, the drive circuit, and other components that constitute the lighting fixture body 80 are connected by wiring (not shown).

The surface of the top plate 81 is painted white so that the light from the light source 82 is efficiently reflected downward.

The lighting device body 80 includes a light receiving unit 85, and is remotely controlled by a remote controller 91 linked to the light receiving unit 85. The remote controller 91 outputs an infrared signal indicating the contents (control contents of how to control the lighting device body 80) instructed by an operation performed by a user or the like. The infrared signal may be, for example, a signal indicating an IR (Infrared) code indicating the control contents. The remote controller 91 outputs an infrared signal indicating the control contents of the lighting device body 80, for example, by outputting an infrared signal indicating an IR code according to the operation contents.

The light receiving unit 85 provided in the lighting device body 80 receives an infrared signal from the remote controller 91. The light receiving unit 85 is composed of a light receiving element (e.g., an infrared sensor) capable of receiving an infrared signal. The light receiving unit 85 converts the received infrared signal into an electrical signal and supplies it to a drive circuit (not shown). The drive circuit controls the light source 82 to turn on/off, adjust the brightness, etc. according to the electrical signal (e.g., the control content indicated by the infrared signal) supplied from the light receiving unit 85. In other words, the light receiving unit 85 functions as a detection unit that detects the infrared signal transmitted from the remote controller 91.

The operation of the light receiving unit 85 and the drive circuit, etc., allows the remote controller 91 to remotely control the lighting fixture body 80. For example, when a user operates the remote controller 91 to turn on the lighting fixture body 80, an infrared signal indicating that the lighting fixture body 80 is turned on is supplied to the lighting fixture body 80, and the control unit 83 receives the infrared signal by the light receiving unit 85 and turns on the light source 82 based on the infrared signal. For example, when a user operates the remote controller 91 to turn off the lighting fixture body 80, an infrared signal indicating that the lighting fixture body 80 is turned off is supplied to the lighting fixture body 80, and the control unit 83 receives the infrared signal by the light receiving unit 85 and turns off the light source 82 based on the infrared signal. Also, when a user operates the remote controller 91 to dim the lighting fixture body 80, an infrared signal indicating dimming and what type of dimming is to be performed is supplied to the lighting fixture body 80, and the control unit 83 receives the infrared signal by the light receiving unit 85 and dims the light source 82 based on the infrared signal. The control unit 83 is electrically connected to the power supply unit 1 through the AC power output terminals 41, 61 and the AC power output cables 40, 60.

The control unit 83 is supplied with AC power from the power supply unit 1 through the lighting mounting adapter 10, and the drive circuit supplies this power to the light source 82. The control unit 83 controls the amount of power (specifically, the amount of current flowing through the light source 82) supplied to the light source 82 according to the infrared signal to control the light source 82. The drive circuit turns on the light source 82 by supplying power to the light source 82. Furthermore, the drive circuit turns off the light source 82 by stopping the supply of power to the light source 82. The drive circuit adjusts the brightness of the light source 82 by changing the amount of power supplied to the light source 82 (specifically, the amount of current). The control unit 83 is provided in a position and shape that does not generate a shadow due to the light from the light source 82. In this way, the control unit 83 functions as a light source control unit that controls the light source 82.

Further, the light receiving unit 85 can be utilized as one of the external electrical devices 100 equipped with the light receiving unit 85 (for example, referred to as a light receiving member) instead of being a component disposed inside the lighting fixture body 80. In this case, the light receiving member is disposed between the DC power output terminal 30 on the lighting mounting adaptor 10 side and the DC power input terminal (not shown) on the lighting fixture body 80 side.
In the same manner as when the light receiving unit 85 is disposed inside the lighting fixture body 80, a control signal for the light source 82 is output by the same processing as described above based on an infrared signal indicating the control content of the lighting fixture body 80 transmitted from the remote controller 91.

The lighting cover 90 is a member that diffuses the light emitted from the light source 82, and covers the entire components that make up the lighting fixture, such as the light source 82 and the control unit 83, from the bottom (light source side). The lighting cover 90 is removably attached to the top plate 81 of the lighting fixture by a locking member or the like provided on the top plate 81. The lighting cover 90 is made of a synthetic resin material such as milky white acrylic resin.

(Embodiment 2)
Next, an auxiliary power supply device for a lighting fixture according to a second embodiment of the present invention will be described with reference to FIG.
Fig. 2 shows a form in which the DC power output terminal 30 in the lighting mounting adapter 10 in Fig. 1 is extended by a DC power output cable 21. By extending the DC power output cable 21 and separating the DC power output terminal 30 from the housing 11, it is possible to supply DC power to a DC power input terminal such as a USB terminal of an external electric device having a short cable or no cable, and it is possible to flexibly accommodate external electric devices.

(Embodiment 3)
Next, an auxiliary power supply device for lighting equipment according to a third embodiment of the present invention will be described with reference to FIG.
3 shows an overall view of an auxiliary power supply for lighting equipment in a form in which a DC power supply device main body 70 incorporating a DC power supply device 50 is attached to a lighting mounting adaptor 10. The DC power supply device main body 70 incorporates the DC power supply device 50. The AC power output cable 40 extending from the lighting mounting adaptor 10 is pulled into the DC power supply device main body 70 through a small hole (not shown) drilled in a side plate 74 of the DC power supply device main body 70, and connected to an input terminal of the DC power supply device 50. The DC power supply device 50 and the lighting mounting adaptor 10 are electrically connected by connecting the AC power output cable 40 to the DC power supply device 50.
Moreover, the AC power output cable 40 branches inside the DC power supply main body 70, one of which is connected to the DC power supply 50 and the other of which extends to the outside as an AC power output cable 60 through a small hole 75 in the bottom plate 73. An AC power output terminal 61 is attached to the tip of the AC power output cable 60.

The DC power supply unit body 70 has a top plate 72 at the top, a bottom plate 73 at the bottom, and side plates 74 on the sides, and is generally cylindrical in shape. It is almost similar in shape to the lighting mounting adapter 10, but has two recesses 71 between the top plate 72 and the side plate 74 so as to include the release lever 17 provided on the lighting mounting adapter 10 (see FIG. 4). If the DC power supply unit body 70 is small enough that its outer shape is inside the fixed position of the release lever 17, it is not necessary to provide the recesses 71. The DC power supply unit body 70 shown in FIG. 3 is smaller than the release lever 17, so it is not necessarily necessary to provide a recess. The top plate 72 and bottom plate 73 are generally circular flat plates, and the top of the top plate 12 is attached to the bottom plate 13 of the lighting mounting adapter 10 by appropriate attachment means.

The details of how the lighting mounting adapter 10 holds and removes the lighting fixture body 80 using a pair of claws 16 and a release lever 17 are as described in the first embodiment above.

In this embodiment, the shape of the DC power supply unit body 70 is the same as that of the lighting mounting adapter 10, but is not limited to this and various shapes such as a rectangular parallelepiped, triangular prism, or octagonal prism can be used.

AC power input to the DC power supply device 50 is converted to DC power and output from the DC power supply output terminal 52 through the DC power supply output cable 51. The output voltage is, for example, DC 5V. An external electrical device having a matching output voltage is connected to the DC power supply output terminal 52. The DC power supply output terminal 52 is usually installed on the bottom plate 73 of the DC power supply device main body 70 so that its tip does not protrude from the bottom plate 73 and is approximately flush with the bottom plate 73.
The DC power output cable 51 may be configured to extend from a small hole (not shown) in the bottom plate 73 of the DC power supply main body 70 .

The DC power output terminal 52 is connected to an input terminal (not shown) provided on the lighting fixture body 80, and supplies DC power to the lighting fixture body 80. The AC power output cable 60 may be branched to provide multiple AC power output terminals 61. The AC power output terminal 61 may be installed on the bottom plate 73 of the body 70 so as to be parallel to the DC power output terminal 52 described below.

The DC power supply unit main body 70, which houses the DC power supply unit 50, is attached to the bottom plate 13 of the housing 11 of the lighting mounting adapter 10. As a simple means for attaching the DC power supply unit main body 70, if the DC power supply unit main body 70 is lightweight, it can be attached using double-sided tape, adhesive, etc. If the housing 11 of the lighting mounting adapter 10 has a metal material such as iron inside, a magnet can be attached to the DC power supply unit main body 70, and the DC power supply unit main body 70 can be attached to the bottom plate 13 of the housing 11 by the magnetic force of the magnet attracting the metal. Attachment using a magnet makes it easier to attach the DC power supply unit main body 70 without the need for double-sided tape, etc.

The bottom plate 13 of the housing 11 and the DC power supply unit 70 may be attached to each other by means of screws. Furthermore, the housing 11 and the DC power supply unit 70 may be attached to each other using an attachment.

(Embodiment 4)
Next, an auxiliary power supply device for lighting equipment according to a fourth embodiment of the present invention will be described with reference to Fig. 4(A) to Fig. 4(C). Fig. 4(A) to Fig. 4(C) are external views of an auxiliary power supply device for lighting equipment that is composed of a lighting mounting adapter 10 and a DC power supply device main body (main body) 70.

Fig. 4(A) is a perspective view of the lighting mounting adapter 10 and the DC power supply device main body 70 as viewed from the side, and Fig. 4(B) is a perspective view of the DC power supply device main body 70 as viewed from the AC power output cable 40 side. Fig. 4(C) is a bottom view of the DC power supply device main body 70 as viewed from the bottom plate 73 side.
In this embodiment, the lighting mounting adapter 10 and the DC power supply main body 70 are both cylindrical and of approximately the same size.
FIG. 4C shows DC power output terminal 52, an AC power output cable 60 extending from a small hole 75 formed in bottom plate 73, and an AC power output terminal 61 attached to the tip of the cable.

As shown in Figures 4(A) and 4(B), the DC power supply unit body 70 has two recesses 71 formed on the upper side (the surface that contacts the lighting mounting adapter 10) of the roughly cylindrical DC power supply unit body 70. The lighting fixture mounting adapter 10 has a pair of release levers 17 on the bottom surface 13 for removing the lighting fixture body 80. These recesses 71 store the release levers 17 so that they do not get in the way when attaching the DC power supply unit body 70 to the lighting mounting adapter 10.

When attaching the DC power supply unit 70, the two recesses 71 are aligned so that the release lever 17 fits into them, and the DC power supply unit 70 is attached to the lighting mounting adapter 10. Therefore, the release lever 17 does not come into contact with the DC power supply unit 70 and does not interfere with the installation of the DC power supply unit 70. The DC power supply unit 70 can be attached to the lighting mounting adapter 10 using the mounting member as described above, or a magnet, double-sided tape, etc. (see Figure 4 (A)).

The AC power output cable 40 extending from the lighting mounting adapter 10 is inserted into a small hole 75 drilled in the side plate 74 of the DC power supply unit main body 70 and connected to the DC power supply unit 50. AC power is supplied from the AC power output cable 40 to the DC power supply unit 50 (see FIG. 4(B)).

The DC power supply unit 70 can be attached to the lighting mounting adapter 10 in the same manner as in embodiment 3 above, so a detailed explanation will be omitted here.

(Embodiment 5)
Next, an auxiliary power supply device for lighting equipment according to a fifth embodiment of the present invention will be described with reference to FIG.
5 is a schematic cross-sectional view showing a state in which an external electric device 100 operated by a DC power source is connected to an auxiliary power device for lighting fixtures according to embodiment 5 of the present invention, which is composed of the lighting mounting adapter 10 shown in embodiment 1 of the present invention, via a USB cable 101 having a USB terminal 102. The external electric device 100 is attached to a bottom plate 13 of the lighting mounting adapter 10. As described above, the external electric device 100 is selected from a system combining, for example, lighting fixtures, various sensors, cameras, audio equipment, infrared communication devices, video equipment, mobile communication devices, wireless communication devices, and the above various devices.

As described above, lightweight external electrical devices 100 can be fixed by directly inserting them into the DC power output terminal 30, such as a USB terminal. Furthermore, among the external electrical devices 100, relatively lightweight ones are attached to the bottom plate 13 of the lighting mounting adapter 10 using double-sided tape, magnets, adhesives, etc., while heavy ones are detachably fixed to the bottom plate 13 of the lighting mounting adapter 10 using a mounting attachment, screw fastening, or other means.

After the lighting fixture body 80, the external electrical device 100, etc. are attached to the lighting mounting adapter 10 (auxiliary power supply device for lighting fixtures), a lighting cover 90 of milky white color or the like is attached to the top plate 81 so as to cover the light source 82 of the lighting fixture body 80. At this time, the lighting cover 90 is attached so as to cover the lighting mounting adapter 10, the lighting fixture body 80, the external electrical device 100, etc. from the front. The external electrical device 100 is usually large enough not to interfere with the installation of the lighting cover 90, but if the size of the external electrical device 100 is too large to fit into the lighting cover 90, the lighting cover 90 may be made deeper or an opening may be provided in the center of the lighting cover 90 to make it a ring-shaped lighting cover 90, or a lighting cover 90 that matches the external electrical device 100 may be used.

In this way, the auxiliary power supply device for lighting fixtures of the present invention has a DC power supply device 50 installed inside the lighting mounting adapter 10 or the DC power supply device main body 70 attached to the lighting mounting adapter 10, holds the lighting fixture main body 80, and is connected to an external electrical device 100, thereby providing a lighting fixture main body 80 that lights up with AC power and an external electrical device 100 that operates with DC power, thereby achieving multi-functionality including a lighting function using the external electrical device 100 as well as a lighting function that brightly illuminates the room. By connecting an external electrical device that runs on DC power to the auxiliary power supply device for lighting fixtures of the present invention, in addition to a lighting fixture, it can be used for a variety of purposes.

In the embodiment of the present invention, the auxiliary power supply for lighting fixtures is mainly exemplified by the lighting fixture main body 80 that is turned on by AC power and the external electrical device 100 that operates by DC power, but the present invention is not limited to this. Depending on the power supply characteristics of the lighting fixture main body 80 and the external electrical device 100 and the number of their arrangements, the required AC power output terminals and DC power output terminals can be provided in the auxiliary power supply for lighting fixtures as appropriate.

As described above, the external electrical device 100 is attached to a high position, such as the ceiling (mounting portion) 18, via a lighting mounting adapter 10. By using a system that combines one or more devices such as various sensors that detect the illuminance in the room, the presence or absence of people, room temperature, etc., an infrared signal transmitting/receiving device for operating indoor devices, a projection device (projecting images, text, etc. onto the lighting cover 90 or a screen installed in the room), a wireless communication repeater (repeater), an infrared surveillance camera, a mobile communication device (3G, 5G, LTE communication, LPWA, etc.), and an audio device (microphone, speaker, etc.), it is possible to obtain a lighting fixture with various functions.

Note that this invention is not limited to the above embodiment, and various modifications and applications of the above embodiment are possible.

In the above embodiment, an example was described in which the lighting fixture body 80 and the external electrical device 100 are attached to an auxiliary power supply device for lighting fixtures that includes a lighting mounting adapter 10 installed on a ceiling (mounting portion) 18, but the location of the lighting mounting adapter 10 is not limited to the ceiling (mounting portion) 18. For example, even if the lighting fixture body 80 and the external electrical device 100 are attached to an auxiliary power supply device for lighting fixtures that includes a lighting mounting adapter 10 installed on the upper part of a wall surface, the same effects as those of the above embodiment can be expected.
