摘 要: 对LED灯具驱动源的技术要求进行分析,设计了恒流式驱动电路.LED灯具采用了电容降压式驱动和TVS对电路进行过压保护。同时采用晶闸管和PTC将输出电路的电流限定在一定范围。为了确保各LED串联支路电流一致,对传统LED连接方式进行分析,并提出了新型的LED阵列结构。 It analyzed the technical requirements of LED lamp driving source, and designed a driving circuit with constant-current. The driving circuit with voltage reduced capacitance and TVS protection for LED florescent lamp. In addition to this, it used lhyristor and PTC will limit the output current to a certain extent. In order to ensure that the branch current of the LED consensus, it analysis the traditional connections of the LED, and proposed a new type of LED array structure.
