Lamp tube capable of being compatible with high frequency and power frequency and implementation method thereof

Abstract

The invention discloses a lamp tube capable of being compatible with a high frequency and a power frequency, which comprises a safety protection circuit, a rectification circuit, an LED driving circuit, an electronic ballast driving circuit A, a leakage current detection protection circuit B1 and an on-site IC driving circuit B2, wherein the safety protection circuit is respectively connected withan input end L and an input end N, the safety protection circuit is also respectively connected with the rectification circuit, the leakage current detection protection circuit B1 and the electronicballast driving circuit A, and the rectification circuit is connected with the on-site IC driving circuit B2. The invention further discloses an implementation method of the lamp tube capable of beingcompatible with the high frequency and the power frequency. According to the invention, the leakage current detection protection circuit B1 is arranged, and due to the fact that the lamp tube is powered on from two ends, the safety of the lamp tube in the dismounting and mounting process is guaranteed; and the on-site IC driving circuit B2 is arranged, unwanted harmonic components in the rectified output current are filtered out, and the constant current is output through oscillation of the on-site IC and a peripheral circuit thereof.

Description

technical field [0001] The invention belongs to the technical field of LED lamp tubes, and in particular relates to an LED lamp tube compatible with high-frequency electronic ballasts and industrial frequency alternating current applications and a realization method thereof. Background technique [0002] At present, there are many types of LED tubes on the market, but when used, according to different principles, its usage methods are also different: some can directly replace compatible ballasts; The lamps need to be matched with different lamp holders to be used normally, and client consumers without relevant professional knowledge can hardly figure out which lamp holder is used in the lamps, so they don’t know how to choose lamps In order to match the existing lamps, it is easy to buy lamps that do not light up or are damaged by misuse. Contents of the invention [0003] The purpose of the present invention is to provide a lamp tube compatible with high frequency and in...
