Thus, the mounting and removing works for the transparent panel can be done easily.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to lighting equipment such as guide lights and indicator lights.

(Prior art) Lighting devices such as guide lights have a light-transmitting panel placed in the opening of the device body, and the light from the lamp built into the device body passes through the light-transmitting panel to provide guidance and other indications. The translucent panel is fitted and held between the engagement grooves formed on the upper and lower edges of the opening of the instrument body so as to be able to slide in the left and right direction, and can be attached to and removed from both ends of the instrument body. Both left and right ends were held in place by end covers attached to the.

However, when installing the fixture on a ceiling or replacing a lamp, it is necessary to remove the light-transmitting panel and leave the opening of the fixture open. Attachment/detaching must be done with one end cover completely removed from the end of the appliance body, and the end cover must be attached/detached to the appliance body which is normally installed in a high position such as a ceiling surface. The process had to be carried out at a high place such as a stepladder, which resulted in poor workability and inconvenience in handling the end cover that had been removed from the device body.

Therefore, the end cover is provided so that it can be slid in a predetermined range in the left and right direction while maintaining the fitted state on the end of the device body, and when installing the device body on a ceiling surface or the like or replacing the lamp, A lighting fixture that can be attached to and removed from an opening by sliding a translucent panel from one end of the fixture body in the left-right direction with the end cover at one end slid toward the outer end of the fixture body. be.

(Problem to be Solved by the Invention) As described above, conventionally, with the end cover at one end slid toward the outer end with respect to the instrument body, the translucent panel is inserted from one end of the instrument body to the left and right. There are lighting fixtures that can be attached to and removed from the opening by sliding in the direction of the light, but the end cover remains at the outer edge of the fixture body and the translucent panel is slid to attach or detach, making it difficult to attach or detach. The back surface of the light-transmitting panel is in surface contact with the front surface of the end cover, making it difficult to slide the light-transmitting panel and holding the light-transmitting panel.

The present invention has been made in view of these points, and an object of the present invention is to provide a lighting fixture in which a light-transmitting panel can be easily attached and detached.
