Description

The present invention relates to a socket for an LED lamp corresponding to an LED lamp having a shape similar to a so-called compact type or twin type fluorescent lamp , and a lighting fixture using the same .

  Recently, as a renewal of indoor facilities for eco-friendly purposes, fluorescent lamps for illumination and the like are often replaced with LED lamps with low power consumption and long life. And so-called compact type or twin type fluorescent lamps (such as FPL36W type) are no exception. For example, as described in the following non-patent document, LED lamps for replacing them are beginning to be marketed.

  In the case of LED lamps that are intended to replace conventional fluorescent lamps, renewal costs can be reduced because there is no need to replace the socket if it is equipped with a base part that can be directly attached to the socket for the fluorescent lamp. be able to. In fact, the LED lamp described in Non-Patent Document 1 also employs a base having the same shape as a conventional fluorescent lamp.

  By the way, the LED lamp causes an internal LED element to emit light by a DC power source supplied from the outside, or receives an AC power source supplied from the outside and causes the LED element to emit light by a DC power source rectified by an internal power circuit. Since it is a mechanism, it is only necessary to provide the base with a pair of power supply terminals. This is a major feature different from the conventional fluorescent lamp that requires two sets (four) of power supply terminals.

  Therefore, even if it is an LED lamp which substitutes for the conventional fluorescent lamp, it is desirable that the socket dedicated to this LED lamp be configured to take advantage of such characteristics. However, when considering a socket for an LED lamp that replaces a compact type or twin type fluorescent lamp, such a type has not been proposed yet.

Accordingly, the present invention provides a socket for an LED lamp having a novel configuration that makes use of the above-described features, particularly an LED lamp that enables crossover wiring, as a socket for an LED lamp that replaces such a compact type or twin type fluorescent lamp. An object of the present invention is to provide a socket for lighting and a lighting fixture using the socket.

  The present invention is a socket corresponding to a base portion of an LED lamp (see FIGS. 6 and 9) manufactured with the intention of replacing a so-called compact fluorescent lamp.

  The compact fluorescent lamp is obtained by fixing the bases of two parallel discharge tubes whose tip portions communicate with each other to a base portion having an elliptical shape. That is, since the straight tube fluorescent lamp is folded at the center and the base portions at both ends thereof are combined into one, the base portion is provided with two sets (four) of power supply terminals.

  On the other hand, the LED lamp is provided with only one set of power supply terminals in the base part. However, since the LED lamp includes an AC drive type and a DC drive type, it is necessary to prepare a socket corresponding to each.

  1 and 2 show an example of a socket proposed by the present invention, which is an AC power supply socket corresponding to an AC drive type LED lamp.

  In these drawings, the socket 1 is formed with a through hole 11f through which a pair of power supply terminals 21 projecting from a lamp base part 20 is formed, and a guide having a base accommodating recess for enclosing the base part 20 therein. A body portion in which a portion 11 and a pair of electrode holes 13 into which a pair of power supply terminals 21 of the LED lamp 2 are attached so as to be tiltable and project from the insertion hole 11f are inserted correspondingly. 12.

  The guide portion 11 is composed of a base housing recess portion 11a in which an inner peripheral wall having an elliptical shape is formed, and a bottom surface 11b in which a rectangular insertion hole 11f for inserting the power supply terminal 21 of the base portion 20 is formed. A pair of locking groove portions 11c that receive locking pieces 20a provided on both sides of the base portion 20 and slide in the back direction are formed on opposite sides of the base housing recess 11a.

  A lamp type limiting projection 11d is formed at a position adjacent to the locking groove 11c on the inner peripheral wall of the base housing recess 11a. The lamp type restriction projection 11d is for restricting the type of lamp that can be mounted in the socket 1 based on, for example, the rated power of the LED lamp 2 or the like. As a matter of course, the base part 20 to be mounted on the socket 1 requires a notch 20b that does not become an obstacle when mounted on the lamp type restriction projection 11d (see FIG. 6B).

  A pair of bearing portions 11e are provided on both outer sides of the bottom surface 11b, and support shafts 12a formed so as to protrude from the main body portion 12 are inserted into the respective bearing portions 11e. Therefore, the guide part 11 can tilt around the support shaft 12a.

  The main body 12 has a substantially rectangular shape, and when the guide 11 is in an upright state with respect to the back of the main body in which the electrode hole 13 for mounting the power supply terminal 21 of the base 20 is formed, that is, the guide When the part 11 is in the base holding position, a guide part accommodating recess 12b for accommodating the guide part 11 including the locking groove part 11c more than half is opened from the front surface to the upper surface.

  On the inner side of the left and right side surfaces of the main body, there is formed a locking piece storage portion 12c for storing the locking piece 20a of the base portion 20 protruding from the locking groove portion 11c of the guide portion 11. The locking piece accommodating portion 12c is a stepped portion that is recessed from the rear surfaces of the left and right side surface portions, and the cross section thereof is opened to the guide portion 11 side. In a state where the guide portion 11 is inclined with respect to the back surface of the main body (see FIG. 1C), the base portion 20 can be freely inserted into and extracted from the base housing recess 11a of the guide portion 11, In this state, when the base part 20 is inserted into the base housing recess 11a of the guide part 11 and then the guide part 11 is brought upright with respect to the back surface of the main body (see FIG. 1B), the base part 20 The locking piece 20a is surrounded by the locking groove portion 11c of the guide portion 11 and the locking piece housing portion 12c, and the base portion 20 is held in a state where it cannot be pulled out by the socket 1. .

  All the electrode holes 13 are formed inside the bottom surface of the main body and open upward. Each electrode hole is embedded with a metal connection terminal of a type sandwiched from both sides like tweezers. The power supply terminal 21 inserted into the electrode hole 13 is pinched by the tweezer-shaped connection terminal to establish an electrical connection.

  The position of the electrode hole 13 is not particularly limited. For example, the square base portion 12d is located at the same location as the socket for the conventional compact fluorescent lamp, that is, at the position facing the bottom surface 11b of the guide portion 11 at the base holding position. May be formed, and each apex of the square may be used as a candidate position for the electrode hole 13, and two positions may be selected therefrom to form the electrode hole 13. In this example, the electrode holes 13 are formed in the upper two places, and the remaining two places are used as places for indicating the electrode names of “L” and “N”.

  3A to 3C are plan views of modifications in which the positions of the electrode holes are different from those in FIG. The present invention can also be applied to such an arrangement of the electrode holes 13.

  Using the main body portion in which the electrode holes 13 are formed at the respective apexes of the base portion 12d, two necessary places may be left, and two unnecessary places may be filled and closed. Since the electrode hole 13 is formed in such four places in the conventional socket for fluorescent lamps, you may divert the part. Further, such a manufacturing method can be applied to a socket corresponding to a DC drive type LED lamp described later. In the socket subjected to such hole filling, two hole filling marks 11 g are generated in the vicinity of the two electrode holes 13. However, the electrode name as described above may be stamped on the hole filling mark 11g.

  In the example of FIG. 4, a power supply connection portion 14 for supplying power by connecting a feeder line corresponding to the electrode hole 13 and a socket adjacent to the socket 1 connected to the power supply 40 are provided on the back surface of the main body. 1 and a power supply connection portion 14 for the crossover wiring provided corresponding to supplying power to the power supply 1 is provided. Each power connection portion 14 is convenient because wiring work can be simplified if it is configured by accommodating a quick connection terminal in the back of a wiring insertion hole formed outside the back surface portion.

  The bottom surface of the main body needs to have a thickness that can secure the depth of the electrode hole 13, so that a space is generated around the electrode hole 13. Can fit in. A lead wire may be used for the wiring member, and a metal plate or the like may be used.

  There is no particular limitation on the connection between the electrode holes 13 and the power connection portions 14, but two power connection portions 14 can be connected to each electrode hole 13 in a corresponding relationship as shown in FIG. That's fine. Then, as shown in the figure, a plurality of sockets 1 can be connected by crossover wiring. Therefore, the connection lines can be shorter than connecting each socket 1 to the AC power supply 40 by individual power lines, and wiring processing is also easy. is there. This is very advantageous in a luminaire using a plurality of LED lamps 2 and the product can be provided at low cost.

  FIG. 5 is an example in which the correspondence relationship between the electrode hole 13 and the power supply connection portion 14 is different. 4 and 5 are merely examples, and other correspondence relationships are possible.

  The LED lamp 2 shown in FIG. 6 is of an AC drive type corresponding to the socket 1 shown in FIG. The LED lamp 2 has a cap 20 fixed to one end of an elliptical cylindrical lamp body 22 and a cap 24 fixed to the other end. The lamp body 22 has a basic structure in which a substrate 24 on which an LED element 25 is mounted is fixed to the upper surface of a metal body 22a, and the light transmission cover 22b is covered on the metal body 22a. The light emitted from the LED element 25 passes through the translucent cover 22b and becomes illumination light. The metal main body 22a is provided with a power supply unit 23 for generating a DC power supply. The base part 20 has a pair of power supply terminals 21 arranged in a projecting manner in the longitudinal direction of the end face. Further, on the peripheral wall surface of the base part 20, the locking piece 20a and the above-described notch 20b are formed. This LED lamp receives an AC power supply through the power supply terminal 21, and turns on the LED element 25 with a DC power source rectified by the power supply unit 23.

  FIGS. 7A to 7C are modifications of the LED lamp 2 in which the arrangement of the power supply terminals is different, and correspond to the sockets shown in FIGS. 3A to 3C, respectively.

  FIGS. 8A to 8D are other examples of the socket proposed by the present invention, and can be a DC power source socket corresponding to a DC drive type LED lamp. FIGS. It should be selected that the arrangement of the power supply holes 13 is different from the AC power supply socket shown in FIG. The configuration other than the arrangement of the power supply holes 13 is the same for any socket 1. In the example of FIG. 8 (a), electrode holes 13 are formed in two places on the right side from the respective vertices of the base portion 12d, and the remaining two places are designated with “+” and “−” electrode names. We use as place to indicate.

  The LED lamp 2 shown in FIG. 9 is of a DC drive type corresponding to the socket 1 shown in FIG. Although it has a shape similar to the LED lamp 2 shown in FIG. 6, it does not include the power supply unit 23, and a point where a pair of power supply terminals 21 are projected in the short axis direction of the end face of the base unit 20. Is different. Further, the LED lamp 2 receives a DC power supply through the power supply terminal 21 and turns on the LED element 25 by the DC power supply.

  10 (a) to 10 (c) are modified examples in which the arrangement of the power feeding terminals is different from that of the LED lamp 2 shown in FIG. 9, and are shown in FIGS. 8 (b) to 8 (d), respectively. Compatible with sockets.

  These sockets may further have one electrode hole for grounding the LED lamp. On the LED lamp side, if a grounding power supply terminal corresponding to the electrode hole is provided in the base portion and a metal main body is connected thereto, an electric shock accident or the like can be prevented.
