たりするおそれがあり、意匠上も好ましくない。The conventional illuminating device has a complicated structure because the first to third three reflectors 40, 45, and 47 are provided in the main body 1. However, there is a problem that not only is it troublesome, but also the cost is increased due to the need for many materials. Further, since the lamp socket 16 is provided further inside the support plate 46 of the second reflecting plate 45 located at a position away from the end plate 4 of the main body 1, the space between the end plate 4 and the lamp socket 16 is provided. is seperated. Therefore, when a normal fluorescent lamp is used as the light source 25, the length of the main body 1 must be increased, and the main body of a general lighting device cannot be used. Further, since the long side 43 of the first reflection plate 40 projects greatly downward from the opening of the main body 1, there is a possibility that the first reflection plate 40 may be deformed or damaged by an object, which is not preferable in terms of design.
