Abstract	本发明公开了一种光源的调节方法及光源。该光源包括：PCB板、LED芯片以及主控元件；其中，LED芯片包括透明衬底，透明衬底安装于PCB板上；PCB板包括通孔，通孔贯穿PCB板露出透明衬底的部分表面；LED芯片与PCB板电连接，用于在发光阶段发光以及在测光阶段感测周围环境的光照强度；主控元件与PCB板电连接，用于根据LED芯片感测到的光照强度调节LED芯片的发光时长和测光时长。通过将LED芯片的透明衬底设置在PCB板上，且设置通孔贯穿PCB板露出透明衬底的部分表面，实现LED芯片在发光阶段发光以及在测光阶段感测周围环境的光照，进而主控元件根据LED芯片感测到的光照强度调节LED芯片的发光时长和测光时长，实现了发光功能和感光功能由同一器件实现，减小了电路复杂性。
Other Abstract	The invention discloses a light source adjusting method and a light source. The light source comprises a PCB, an LED chip and a main control element, wherein the LED chip comprises a transparent substrate, and the transparent substrate is installed on the PCB; the PCB comprises a through hole, and the through hole penetrates through part of the surface, exposed out of the transparent substrate, ofthe PCB; the LED chip is electrically connected with the PCB and used for emitting light in the light-emitting stage and sensing the illumination intensity of the surrounding environment in the lightmeasuring stage; and the main control element is electrically connected with the PCB and used for adjusting the light-emitting duration and the light measuring duration of the LED chip according to the illumination intensity sensed by the LED chip. The transparent substrate of the LED chip is arranged on the PCB, and the through hole is formed to penetrate through part of the surface, exposed outof the transparent substrate, of the PCB, so that the LED chip emits light in the light-emitting stage and senses the illumination of the surrounding environment in the light measuring stage; and then the main control element adjusts the light-emitting duration and the light measuring duration of the LED chip according to the illumination intensity sensed by the LED chip, so that the light-emitting function and the light sensing function are achieved through the same device, and the circuit complexity is reduced.
