基于STM32的照度稳定可调的LED台灯设计

Design of LED Table Lamp with Stable and Adjustable Illumination Based on STM32

随着发光二极管(Light Emitting Diode,LED)技术的飞速发展,LED灯凭借高效、节能、环保等优点广泛应用于智能照明领域。笔者基于STM32H750平台提出一种照度稳定可调的高效LED台灯设计方案。该方案可以根据环境的明暗变化,自动跟踪环境光的变化调节亮度,也可以手动调节LED台灯的亮度,且亮度均匀稳定。通过实验验证了所述方案的可行性及正确性,具有一定的实用意义和参考价值。

With the rapid development of LED technology, LED lamps are widely used in various intelligent lighting fields for their advantages of high efficiency, energy saving and environmental protection. This paper puts forward a design scheme of highefficiency led table lamp with stable and adjustable illumination,based on STM32H750 platform.The scheme can automatically track the change of ambient light and adjust the brightness according to the light and dark change of the environment, or manually adjust the brightness of LED table lamp, and the brightness is uniform and stable.The feasibility and correctness of the method are verified by the experiment, which has certain practical significance and reference value.
