Description

[Detailed description of the invention] [Technical field] This invention relates to lighting equipment such as spot lights.

[Background technology]

Conventionally, there was a device in which the fixed part and the movable part that became the lighting side were connected by a connecting plate (for example,
No. 76685) had the disadvantage of poor heat dissipation because it did not have many heat dissipation slits.

[Purpose of invention]

The purpose of this invention is to provide a lighting fixture that has a good heat dissipation effect and can have a wide rotation range.

[Disclosure of invention]

This idea consists of a device body with openings on the front and side surfaces and a number of lateral rows of heat dissipation slits continuous from the top to the back, and a lamp socket that is installed inside the device body and exposed through the opening on the front surface. a socket base, an arm that is passed through the heat dissipation slit and rotatably attached to the socket base from an opening in a side surface of the instrument body, and has a notch that engages with an end of the heat dissipation slit; It is equipped with a cap that closes off the sides of the cap.

According to the structure of this invention, a large number of heat dissipation slits are formed, so the heat dissipation effect is good, and since a notch is formed in the arm, the rotation range of the instrument body can be increased without making the heat dissipation slits long. Moreover, since the attachment portion of the arm is not visible from the outside, the appearance is improved and the instrument body can be made more compact.

An embodiment of this invention is shown in FIGS. 1 and 2. That is, the instrument main body 1 is a synthetic resin box whose top surface 2, rear surface 3, and bottom surface 4 are continuous in an arc shape or U shape, and has openings 7a on the front surface 5 and both side surfaces 6.
7b, and a large number of heat radiation slits 8 extending across the upper surface 2 and the rear surface 3 are arranged in rows in the direction of the side surface 7b. A socket base 9 is installed in the appliance body 1 through an opening 7 in the front face 5, and a lamp socket 10 is installed therein. Further, a shade 11 and a mounting spring 12 are attached to the edge of the opening 7a of the front surface 5, and a recess 16 of the mounting body 15 of the glass reflector 14 is press-fitted and locked into the engaging tongue piece 13 of the mounting spring 12. The arm 17 has a notch 19 on one side near the mounting hole 18, is passed through the end of the heat dissipation slit 8, and is opposed to a screw hole 20 provided in the socket base 9. The screw 21 is passed through the opening 7b of the side surface 6 of the instrument main body 1 into the mounting hole 18, and the washer 22 and spring washer 23 are interposed therebetween, and the screw 21 is inserted into the screw hole 20.
The arm 17 is rotatably attached to the socket base 9 and is frictionally locked. 24 is opening 7
The cap 25, which is an example of a rubber cap that closes the cap 25, is a lamp that is attached to a socket.

FIG. 2 shows the arm 17 in an attached state, and the notch 19 of the arm 17 engages with the end of the heat dissipation slit 8 as shown in the imaginary line, and has a large opening inside the main body. Therefore, in the state shown by the solid line in the figure, the opening of the heat dissipation slit 8 is opened more than in the case without the notch 19, and the slit 8 can be rotated to the position where it engages with the end 8a of the slit 8 as shown in the imaginary line. The rotation range can be secured without increasing the length.

With this structure, the flexible mechanism part of the arm 17 is attached to the socket base 9, so that the flexible mechanism part does not appear on the outside, and there is no need for a knob. When viewed from the rear with the device attached, the heat dissipation slit 8 is located above the main body, so it is almost invisible, and a sufficient heat dissipation effect can be obtained. The heat radiation slit 8 itself serves as a stopper for the arm 17, and there is no need to provide a separate stopper. Furthermore, the lead wire can be taken out using the heat dissipation slit 8.
Furthermore, the overall device can be made more compact than in the case of conventional externally attached arms.

[Effect of idea]

As mentioned above, according to the lighting equipment of this invention,
The large number of heat dissipation slits provides good heat dissipation, and the notch in the arm allows for a wider range of rotation of the instrument body without making the heat dissipation slits longer. This has the effect of not only improving the appearance but also making the instrument body more compact.
