Abstract

The present invention relates to an electric driver for fluorescent lamp, comprising an input circuit for rectifying and filtering an inputted alternating voltage with certain amplitude and a power factor correction circuit for further amplifying the voltage rectified and filtered by the input circuit to obtain a stable DC voltage with higher amplitude. The electric driver further comprises an output circuit for receiving the DC voltage outputted from the power factor correction circuit as its operating power supply, and providing the fluorescent lamp with an output without input transformer and without output transformer.

Description

technical field [0001] The present invention relates to an electronic driver, in particular to an electronic driver for fluorescent lamps. Background technique [0002] Fluorescent lamp is a kind of high-pressure gas discharge lamp, which is widely used in people's daily life because of its good brightness, no flicker, long life and energy saving. Such as industry, agriculture, streets, exhibition centers, square parking lots, industrial and mining enterprises, large clubs, etc. [0003] At present, the world is facing more and more serious energy shortages, and it is urgent to require people to save energy in daily life and public facilities. Fluorescent lamp itself is a mature product, but its drive circuit used in the past has a low circuit frequency, large inductor power consumption, low efficiency and high cost. Therefore, for a long time, people hope to obtain an electronic driver for fluorescent lamps with energy saving, high efficiency, wide input voltage operating...
