Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is directed to a single-cap discharge lamp having, for example, a substantially U-shaped or substantially T-shaped light emitting section, which is placed horizontally between the inner surfaces of a reflector. Regarding lighting equipment placed and used in.

(Prior art) In lighting equipment that uses a single-cap discharge lamp placed horizontally between the inner surfaces of a reflector, it is difficult to connect and pull out the lamp horizontally from a lamp socket placed inside the reflector. It was difficult to attach and detach the lamp, and moreover, when removing the lamp from the lamp socket, there was a risk that the tip of the lamp would hit the inner surface of the reflector and be damaged, so it was necessary to operate carefully.

Therefore, as shown in Japanese Utility Model Application Publication No. 60-40909, for example, the tip of the lamp is made tiltable with respect to the reflector, and when the lamp is removed (reversed when installed),
Rotate the tip of the lamp horizontally between the inner surfaces of the reflector downward, remove the tip of the lamp from the inner surface of the reflector, and expose it diagonally downward, without hitting the tip of the lamp against the reflector. Some are designed to be pulled out from an oblique direction. This has a lamp socket that is supported by a socket fixture on the outside of the reflector so that it can rotate freely between the horizontal direction and diagonally downward. The through hole for connecting the lamp is opened wide along the vertical direction so as not to interfere with the tiltable lamp, and the lamp base is connected to the lamp socket on the outside of the reflector through this through hole. .

(Problems to be solved by the invention) As described above, in the structure in which the lamp socket placed on the outside of the reflector can be rotated together with the socket mount, the structure of the rotating part is complicated and large, and it takes up space. Furthermore, in order to avoid interference with the rotating lamp, it is necessary to provide a large through hole in the reflector, and the inside of the lighting fixture can be seen through the through hole, spoiling the appearance.

Furthermore, since the lamp socket is disposed outside the reflector, it is difficult to connect the lamp to the lamp socket through the through hole of the reflector.

The present invention was developed in view of the above-mentioned problems, and has a simple and compact structure that allows the lamp socket to be tilted freely, and also reduces the opening of the reflector and hides the opening of the reflector to improve the appearance. It is an object of the present invention to provide a lamp lighting device that can be manufactured satisfactorily and in which the lamp connection operation can be easily performed.
