PURPOSE:To prevent the glare of a lighting system so as to irradiate the front surface of a light shielding portion during lighting at night and enhance an lighting effect and a decorating effect by disposing the light shielding portion before a lamp inside of a cover, and providing an incident portion before a portion where light from the lamp enter the cover and reaches the light shielding portion. CONSTITUTION:A light shielding portion 4 positioned before a lamp 1 is adapted to prevent the glare of the lamp 1 when the lamp 1 is lighted. Light incident into a material of a cover 3 from a back portion 8 and diffusing portion 9 of a side piece 7 of the cover 3 during lighting penetrates the light shielding portion 4 through the cover 3, thus constituting an incident portion 5. Light of the lamp 1 emitted from the incident portion 5 irradiates the light shielding portion 4 from the obverse of the cover 3. Since the light of the lamp 1 irradiates the light shielding portion 4 while reflection at a critical angle inside the material of the cover 3 is repeated, the light shielding portion 4 can be decorated by the light without becoming a shade in dark in spite of prevention of the glare by the light shielding portion 4 disposed before the lamp 1, thereby preventing the glare. |
