DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide light having a display panel mounted on a main body of an appliance.

[Prior art]

This type of guide light is described, for example, in the microfilm of Japanese Utility Model Application No. 54-144159 (Japanese Utility Model Application Publication No. 56-56106). An opening for mounting a rectangular display panel is formed in the fixture main body of the guide light, and a pair of engagement grooves with which the upper and lower edges of the display panel are engaged are formed on the upper and lower edges of the opening. . The engagement groove is formed by arranging the reflector and the lamp body with a gap so that the gap is slightly larger than the thickness of the display panel. The mounting of the display panel is performed by inserting the upper and lower edges of the display panel into the engagement grooves of the upper edge of the opening from the side of the device main body, and the display panel is engaged with the upper and lower engagement grooves. .

[Problems to be solved by the invention]

However, in the conventional guide light, when the display panel is mounted on the instrument body from below, it is difficult to position the upper and lower edges of the display panel in the engagement grooves, and the mounting property is poor. Further, since the gap is formed by arranging the reflector and the separate members such as the main body, the manufacturing variability of the gap is apt to occur, which may further deteriorate the above-mentioned mountability. In particular, with the above-described guide light, it is difficult to grasp the position of the engagement groove from the side. In addition, the guide light is relatively often installed at a high place in order to enhance the visibility, and the display panel must be mounted from the side. In addition, in this guide light, since the lamp is disposed near the upper edge of the fixture body, there is a possibility that brightness unevenness may occur on the display surface. SUMMARY OF THE INVENTION It is an object of the present invention to provide a guide light having an improved workability by allowing a display panel to be easily attached to an appliance body.
