Adequate illumination: LED lighting instant start and achieve the rated flux and no switching losses, LED light-emitting Angle can be adjusted to meet your variety of lighting needs.
LED照明瞬时启动，并达到额定光通量而且无开关损耗，LED发光角度可调节，满足您多种照明需要。
However, if the optical concentrator 108 is designed for a limited Angle acceptance, the radiance of the light emitting device 102 can still be maintained.
然而，如果光学集中器108被设计用于有限的角度范围，那么仍可维持发光装置102的辐射率。
