| Abstract: | 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. |
