Abstract

The invention is applicable to the field of LED lamps, and particularly relates to an LED driving circuit and an LED taxiway edge light. The current of the LED driving circuit is transformed from high to low by an industrial frequency transformer, the LED driving circuit is simple in structure, the current and voltage are efficiently transformed by charge and discharge of an energy-storage capacitor, accordingly, energy consumption of the LED driving circuit is reduced, the adaptability of the driving circuit is higher by the aid of a voltage limiting protection circuit, and the driving circuit is protected from damage.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to an LED drive circuit and an LED taxiway edge light. Background technique [0002] At present, the navigation aid lamps used in most domestic airports are still lamps with traditional light sources, such as metal halide lamps. The lamps using this light source have the advantages of simple circuit, safety and reliability, but the life of the halogen lamp light source is short, generally about 1000 hours, so the lamps using the halogen lamp need to replace the light source frequently, and the maintenance cost is extremely high. [0003] With the continuous development of solid-state light source LED technology, it has become possible to apply LED lighting technology to the field of airport aviation lighting. The LED light source has the advantages of long life and energy saving. More importantly, it can avoid the problem of high maintenance cost caused by frequent replacement of the light...
