一种低成本机控冰箱柜LED照明灯设计

Design of a Low Costly LED Lamp for Mechanical Refrigerator and Freezer

高效节能的LED技术已经普遍应用在家电照明当中,机控冰箱柜通常使用阻容降压方案的自整流LED灯,但其成本仍然较高。本文提供一种基于高压线性恒流驱动方案的LED照明灯设计,整板设计成本低;同时提供LED照明灯的结构装配设计思路,为相关人员提供参考。

LED technology with high efficiency and energy saving has been widely used in household appliance lighting.Auto-rectifying LED lamp by Resistance and capacitance step-down scheme is usually used in mechanical refrigerator and freezer.But the cost is still high.This article provides a design of a LED lamp by AC IC direct driver scheme,which the cost of the whole board design is low.Also provides a design idea of structural assembly for LED lamp to the relevant personnel.
