机动车LED前照灯
摘要：
已有机动车前照灯使用了LED但对电能的利用水平不高。现在机动车LED前照灯内设置有LED和控制器，所述控制器对所述LED按频率≥24Hz/S进行同步交替供电与截止，使这些LED同步按频率≥24Hz/S进行发光，这给人眼的感觉是这些LED在同时连续发光。本方案充分利用了电流脉冲对LED发光强度的提升作用，解决了现有机动车前照灯对电能利用率不高问题，灯的亮度有一定提高，可取得较好的使用效果。
摘要（英）：

A headlight of the prior motor vehicle adopts LEDs but the utilization level of electric energy is low. The LEDs and a controller are arranged in the LED headlight of the prior motor vehicle, power supply and cut-off of the LED are carried out synchronously and alternately by the controller according to the frequency of more than or equal to 24Hz/S so that the LEDs can illuminate synchronously according to the frequency of more than or equal to 24Hz/S, which brings a visual impression that the LEDs illuminate continuously and synchronously. The proposal utilizes current pulse to increase LED luminous intensity, which solves the problem of low utilization rate of electric energy of the prior motor vehicle; and the brightness of the light is enhanced, thereby having better use effect.
