Problems solved by technology

[0004] However, the above-mentioned reflective cover of the existing LED lighting device only has a single-curvature reflective surface, so it can only collect the upward and forward light from the LED light source, and it is often difficult to collect part of the backward light, resulting in leakage. It is difficult for a reflective surface with a single curvature to effectively gather all the light onto the mask, which will cause loss of light energy and cause waste

Abstract

The invention relates to an LED light emitting device and a vehicle lamp, wherein the LED light emitting device comprises an LED light source, a reflection cover, a masking film and a projection lens, the LED light source comprises at least one LED element, the light emitting surface of the at least one LED element faces to the reflection cover, the reflection cover is covered outside the at least one LED element and contains a plurality of reflecting surfaces with different curvatures, the masking film is used for adjusting the rays converged from the reflecting surfaces into a preset light form, and the projection lens is used for outwards projecting the preset light form. The vehicle lamp comprises a plurality of LED light emitting devices. Through the LED light emitting device and the vehicle lamp, the leakage loss of light energy can be avoided, and the purposes of energy saving and environmental protection are achieved.

Description

technical field [0001] The present invention relates to an LED lighting device, especially an LED lighting device and an LED vehicle lamp, which can make more effective use of light energy. Background technique [0002] Light-emitting diodes (LEDs) are widely used in lighting sources due to their characteristics of power saving, small size, and long life. For example, they are used in automobile lights, direction lights, and brake lights. [0003] Existing projection-type LED light-emitting devices used in vehicle lamps, such as Taiwan Patent No. I 281971, discloses a "projection-type LED vehicle lamp", which mainly includes an LED light source, a reflector, a mask and a lamp shade. The light-emitting surface of the LED light source faces upwards and is perpendicular to the light-emitting direction. The reflector is installed above the LED light source to concentrate the light of the LED light source and emit to the front cover position, so as to adjust the light shape in co...
