ABSTRACT:
A lighting apparatus constructed by holding a linear light source, a radiating plate, a reflecting plate, a light guiding plate, a diffusing plate, and a lens between upper and lower frames. One of the upper and lower frames is provided with pins. The other frame, the radiating plate, the reflecting plate, the light guiding plate, the diffusing plate and the lens have holes in locations corresponding to the pins. The upper and lower frames have protrusions and recessions into which the protrusions are fitted, respectively. The lighting apparatus is easily assembled without using vises by fitting the pins into the holes of the respective component members to place them in position and engaging the protrusions and the recessions of the upper and lower frames. Moreover, a harness of the linear light source is inserted into a slit formed on a surface of the upper frame which does not face the linear light source, and fixed by a stopper. It is thus possible to provide a lighting apparatus with excellent maintainability at reduced costs.
