Abstract

The invention discloses a method for achieving intelligent start control of an electronic ballast through timing control. The electronic ballast comprises a rectification filtration module used for converting alternating currents into direct currents, and a boosting resonance module used for generating oscillating voltages which are output to a load after boosting is conducted on output voltages of the rectification filtration module. A voltage feedback end is arranged on an output circuit of the boosting resonance module, a timing control module used for controlling the boosting resonance module to work is connected with the voltage feedback end, and the timing control module is used for controlling the boosting resonance module to be stopped or started according to the output voltages, collected by the voltage feedback end, of the boosting resonance module. By means of the method, the problem of the electronic ballast in the repeated self-recovery starting process in the prior art is effectively solved, intelligent recovery start for controlling the electronic ballast is achieved, the damaged probability of devices is lowered, device energy consumption is reduced, and the service life of the devices is prolonged.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a method for realizing intelligent start-up control of electronic ballasts through timing control. Background technique [0002] At present, street lamps, highway tunnel lights, industrial and mining lamps, square and factory lighting mostly use high-pressure gas discharge lamps, which require extremely high driving voltage. The general driving starting voltage is as high as 2.5KV or more. When the temperature is high, its start-up voltage will rise above 10KV, so that the output of the existing electronic ballast rises above 10KV, and the following situations will occur in the case of high voltage (1) The output power of the electronic ballast is too high and damaged. (2) Impacting the lamp tube under the condition of 10KV high voltage will shorten the life of the lamp tube, such as continuous self-recovery startup, the components will not stop working, resulting in damage to the lamp...
