PROBLEM TO BE SOLVED: To provide a lighting system which facilitates wiring, and reduces an effect to the circumference even if its electric means is over-heated. SOLUTION: A flat top board part 14 is projected overchanging the upper end surface of a roughly cylindrical side wall part 13 widely opened downward while being integrally blocked so as to be formed into a roughly box shaped equipment main body formed out of metal plates. A mount fitting 18 in a L shape in cross section to which a lighting device 22 electrically connected with a lamp socket disposed in the inside of the equipment main body 12, is mounted to the lower surface of the projected portion of the top board part 14. The portion of the top board part 14 formed in the overhanging above the lighting device 22, is turned out to be a cover part 23. The distance of the cover part 23 from the tip end periphery of the top board part 14 shall be more than 15mm, the distance from both the side peripheries of the top board part 14 shall be more than 30mm respectively, and the cover part is thereby extended around the upper circumference of the lighting device 22. Wiring exposed outside can be facilitated, the lighting device 22 is prevented from being stained by dust by the cover part 23, and an influence to the circumference can thereby be restrained even if the device catches fire, and burnt. |
