Preferably, in this majority reflecting surface, at least respectively have top and rear that a reflecting surface is positioned at this led light source.
Preferably, the reflecting surface that is positioned at the led light source rear is a photoreactivation reflecting surface surplus in the of.
Wherein, each reflecting surface and the interelement distance of this at least one LED to be being preferable greater than 20 millimeters, but be not with the application range of restriction this case.
The present invention comprises the LED car light of most above-mentioned LED light-emitting devices of a use in addition.
The attainable concrete effect of the present invention comprises:
1. the present invention makes the reflector of LED light-emitting device have the reflecting surface of at least two different curvature, photoreactivation reflecting surface surplus wherein a reflecting surface can be used as one, therefore the light backwards that this led light source sent can be subjected to the reflection of this surplus photoreactivation reflecting surface and be concentrated on the projection lens of the place ahead, avoid the leakage of luminous energy, and then reach the purpose of saving luminous energy, reduce cost and meet environmental protection.
2. the present invention further makes the LED light-emitting device utilize two trapezoidal high-brightness LED elements to be the combination of arranging in opposite directions, with the purpose of reaching heat radiation and the light shape and the Luminance Distribution that also can meet the auto bulb rules.
3. the present invention makes the reflector of LED light-emitting device have the reflecting surface of most different curvature, is concentrated on the matte of the place ahead in order to light is converged, and sees through projection lens and throw away, makes the light shape of its generation more meet the standard of rules.
