DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a lighting fixture.

[0002]

2. Description of the Related Art In recent years, as lighting equipment has been turned on at high frequencies, an apparatus having an insulating plate between a metal body and a lighting circuit board has been adopted.

[0003]

However, the insulating plate only performs an insulating function between the metal body and the lighting circuit board, and no further function is assigned to the insulating plate. That is, no attempt has been made to allocate and assign a function other than the original function to the insulating plate. The present invention has been made in view of the above point that it has not been rationalized, and has as its object to provide a rationalized lighting device by allocating a function as (an outer shell of) an electric component to an insulating plate.

[0004]

To summarize the present invention, in order to solve the problems], is a luminaire formed integrally with the power terminal block, which is also used as power supply terminal block furthermore Mamedama socket insulating plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described. However, these are merely exemplary embodiments adopted based on the present invention, and the present invention is limited to matters unique to only the embodiments. The technical scope of the present invention must be determined based on the matters stated in the claims or matters that are substantially equivalent thereto.

The lighting apparatus according to the illustrated embodiment has an insulating plate 3 made of a synthetic resin between a main body 1 made of metal and a lighting circuit board 2 on which high-frequency lighting circuit components such as transistors and LCR components are mounted. I have. A power terminal block (outer shell) 5 for receiving an AC power AC is formed integrally with the insulating plate 3, which also serves as a bead ball socket 4.
The power supply terminal block 5 is also provided with a feed power supply terminal 6 for supplying the received AC power supply AC to another lighting device (not shown).

More specifically, at the center of the main body 1, a substantially rectangular or substantially elliptical convex portion 7 is formed so as to protrude toward the bottom surface, and a hole 8 is formed at the center of the convex portion 7. The hole 9 formed in the center of the insulating plate 3 is formed in a substantially rectangular shape or a substantially elliptical shape corresponding to the shape of the convex portion 7, and the insulating plate 3 is formed such that the convex portion 7 is fitted into the hole 9. 1
Attached to the bottom side of The power supply terminal block 5 is arranged on the insulating plate 3 at a position close to the hole 9. Further, a hanging adapter (not shown) is provided which is electrically and mechanically connected to a well-known hanging rosette (not shown) mounted on the ceiling. As is well known, a locking portion formed of, for example, a locking groove is formed on the outer circumference of the hook adapter, and the mounted member 10 is locked and mounted on the locking portion.

A release portion 11 is provided on both sides of the mounted member 10 to be able to release the locked state by being displaced outward, and the release portion 11 is displaced into a central hole 12 of the mounted member 10. The engaged portion (not shown), which has been projected by the spring, is separated from the engaging portion, and the attached member 10 is separated from the hooking adapter. This makes the lighting fixture removable. The mounting member 10 also serves as a power receiving unit that receives the AC power supply AC supplied to the hook adapter, and a power receiving unit 13 that is inserted into the bottom surface of the hook adapter and receives power is provided integrally with the mounting member 10. Can be The power receiving unit 13 is connected to the power supply unit 14 inside the mounted member 10, and the power supply unit 14 is inserted and connected to the connection hole 15 near the hole 9 in the power supply terminal block 5.

The attached member 10 is fixed to the projection 7 of the main body 1 by appropriate means. Although the insulating plate 3 is temporarily fixed by the attached member 10 by this fixing, the insulating plate 3 itself may be fixed to the main body 1 by appropriate means. Next, the lighting circuit board 2 is fixed to the insulating plate 3 by a suitable means such as a support tool. On this occasion,
Connector 2 provided inside a substantially U-shaped lighting circuit board 2
a is connected to the secondary terminals 5a, 5a, 6, 6 of the power supply terminal block 5. The terminal 5a that is directly connected to the AC power supply AC is connected to the switch 16 via the connector 2a and the printed pattern of the lighting circuit board 2, and the other terminal 5a is connected to the secondary output of the switch 16. The inner end of 5 a is configured as a side contact piece 4 a in the bead ball socket 4. Note that an AC power supply AC is directly connected to the center contact piece 4b in the bead ball socket 4. The feed power terminals 6, 6 are connected to a feed power connector (not shown) via a connector 2a and a printed pattern of the lighting circuit board 2. A switch 16 is connected and fixed to the lighting circuit board 2 via a connector, and a socket 17 for connecting a fluorescent lamp (not shown) is connected and fixed to a connector 18 of the lighting circuit board 2. Next, the reflecting plate 19 serving as a lower cover is fixed to the main body 1 by an appropriate means such as a screw. At this time, the lamp support 20 is also fixed to the main body 1 together with the reflecting plate 19. The bead ball 21 is mounted on the bead ball socket 4. An arm 22 for guiding and suspending a drawstring (not shown) from the switch 16 is attached to the upper surface of the main body 1, and a leaf spring-like elastic body 23 for elastically pressing the main body 1 against the ceiling is fixed to the upper surface of the main body 1. You. In addition, as an embodiment, the bead ball socket 4 and / or the power supply terminal block 5 may be independently provided on the insulating plate 3.

The lighting apparatus according to the present embodiment has a metal main body 1.
And a lighting circuit board 2 and an insulating plate 3 provided on a bead ball socket 4 or a power terminal block 5 and a bead ball socket 4
The power supply terminal block 5, which is also used as the power supply terminal block 5, is integrally formed, and the function as (the outer shell of) the electric component is assigned to the insulating plate 3, thereby providing a streamlined lighting fixture. Further, if the power supply terminal block 5 is provided with a feed power supply terminal 6 for supplying the received AC power supply AC to another lighting fixture, further rationalization can be achieved. Thus, the components of the lighting fixture can be rationally integrated, which contributes to an improvement in productivity.
Further, it is possible to construct a base that can be rationalized by omitting the wiring cords conventionally wired to the bead ball socket and the power terminal block.
