Abstract:
In this paper, a design of a self-adapted LED desk lamp is presented. The illuminance on the work plane and colour temperature of the hybrid light are measured by the multi-channel colour sensor TCS3414CS. The MCU embedded in the lamp will adjust the LED driversТ output to maintain constant illumination. Experimental results show that, no matter how the ambient light changes under different scenes, the lamp can still provide satisfactory lighting condition with both illuminance and colour temperature adjusted to a predefined value, leading to a more comfortable user experience.
