Abstract:
The present invention provides a light emitting device for a vehicle, which enables the light intensity in a ring configuration of the light guide structure uniform. In the light guide having a body (12) and vehicle light emitting device using the light guide member (12) along an annular cylindrical structure is blown from the rear surface (22) of the light guide body (12) along the light guide (12) of the annular direction of the light emitted from the light source leaving the light guide body (12) emit light, and the light guide body (12) of the rear surface (22) and the outer peripheral surface (24) is provided to adjust the light reflecting sheet (31). Adjustment of the light reflecting sheet (31) is formed in the lower light emitted from the light guide body (12) near the light reflectance of the light emitting portion and the light reflectance as the distance from the light source (11) and increased, and therefore by the guide (12) is blown along the inner circumferential surface of the cylinder of the annular structure is formed in the light leaving the light guide body (12) of uniform light intensity, the light emitting device can be a vehicle to seek higher functionality, which can respond by car various human preferences.
