照明装置
Document Type and Number:
Japanese Patent JP4786750
Kind Code:
B2
Abstract:
The present invention provides a lighting apparatus that can prevent the deformation such as bending of a lighting apparatus main body. A lighting apparatus 100 includes a LED module 2 provided at the central side of a chassis 1 and a reflection sheet 4 reflecting light emitted from the LED module 2. The LED module 2 emits light to the outer edge portion of the chassis 1 and then the light is reflected on the reflection sheet 4 to perform illumination so that glare can be reduced. Then, the light emitted from the LED module 2 is reflected on the reflection sheet 4 in many directions so that a substantially uniform illuminated light with less illumination unevenness can be achieved. The LED module 2 is not arranged at the outer edge portion of the chassis 1 so that moment acting on the chassis 1 can be reduced. Therefore, the deformation of chassis 1 can be prevented.
