<P>PROBLEM TO BE SOLVED: To provide an explosion-proof lighting apparatus and an explosion-proof lighting system wherein generation of ignition source for igniting the inflammable gas flowed into the explosion-proof lighting apparatus is prevented, and the structure of at least the portion where the lighting device is installed is constituted of a safety-increased explosion-proof structure, and simplicity and low cost is realized. <P>SOLUTION: In the explosion-proof lighting apparatus 10, when a prescribed DC voltage is supplied from a power supply part through an electric cable 203, electric power is supplied to a lighting part 300 adopting a lamp structure through the electric cable 103. When power is supplied to the lighting part 300, an LED lamp 311 emits light. And the light emitted from the LED lamp 311 is diffused by an optical diffusing plate 314 and passes through a light transmission part 104 and is irradiated outside. Since the lighting part 300 having the LED lamp 311 is made a structure electrically insulated from the outside, the structure is simplified. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
