PURPOSE: To expand irradiation quantity and irradiation range as an illumination device, improve the appearance thereof, and give expansion of room space due to random reflection of light to resident, etc.

CONSTITUTION: A dressing frame 5 constituting a shade integrally attached to an illumination device main body serves as a louver 6 having a bending part formed so as to protrude toward upward, and its surface has a gold or silver colored metal film layer. Thereby, the reflection of the light of a lamp 3 is ensured to the oblique downward direction of the illumination device main body, its irradiation quantity can be expanded, the light reflected on the outside of said louver is randomly reflected in the oblique upward direction, therefore, its appearance is improved, the side direction of the illumination device main body is made brighter, and the expansion of room space can be expressed by expansion of the light of the lamp.
