[0004]目前,对LED光源的聚光方式一般采用抛物面的反光杯,但是这种方式要实现发光角非常小(如发光角小于5度)需要将反光杯尺寸做得比较大,否则LED光源发光角较小的光线无法被利用,导致LED光源最终的发光角较大,同时浪费大量的制造材料。 [0004] Currently, the way of collecting the LED light source commonly used in the parabolic reflector, but this approach to achieve a very small emission angle (light-emitting angle is less than 5 degrees) need to be made relatively large size of the reflective cup, the LED light source or smaller emission angle beam can not be utilized, resulting in a final LED light emitting angle is large, while the waste a lot of manufacturing material. 也有采用凸透镜对LED光源进行聚光的,但这种方式LED发光角较大的光线无法被利用,对LED光源光通量的利用率比较低,最终导致灯具的光效利用率太低。 There is also a convex lens for converging the LED light source, the LED light emission angle is large this way light can not be utilized, the utilization of the luminous flux of the LED light source is relatively low, resulting in low utilization efficiency of the light fixture.
