A device for lighting electric light source via multi-channel output

Abstract

The invention discloses a device of a multiplexed output lightening electric light source. An AC power supply is respectively communicated with the active filter circuit and a pulse delay phase-shift circuit through an active filter circuit, a high frequency rectification filter circuit CF, and a high frequency switching mode power supply control circuit in sequence. The high frequency switching mode power supply control circuit adjusts the oscillation frequency according to different electric light source loads, generates two way interlocked positive pulse outputs which are delayed and phase-shifted by the pulse delay phase-shift circuit, and realizes the multiplexed output high frequency voltage and current as well as the multiplexed output lightening electric light source. The invention has the beneficial effects that the strobe and the stroboscopic effect of the electric light source are effectively eliminated, the illuminating quality is improved obviously, and the input current harmonic component is reduced, thereby causing the electric light source to obtain higher photoelectric transformation efficiency on the premise that the lower power is used, and achieving the purposeof saving the electric energy.

Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a device for lighting electric light sources with multiple outputs. Background technique [0002] The traditional way of lighting the electric light source is to use a single-phase power supply, and light up multiple electric light sources connected in parallel in the single-phase power supply circuit through switches; currently, household electric light sources can be basically divided into three types: ordinary lamps (tungsten), halogen and fluorescent lamps. In the case of grid voltage 220V, the actual working current of several commonly used electric light sources: [0003] 400W high pressure sodium lamp single lamp, working current is 4.2A. [0004] 250W high pressure sodium lamp single lamp, working current is 2.5A. [0005] 400W metal halide lamp single lamp, working current is 3.8A. [0006] 250W single metal halide lamp, working current is 2.3A...

Problems solved by technology

However, some energy-saving lamps with poor technical quality on the market still have a strobe depth as high as 20%-30%.

[0011] In the prior art, due to the low utilization rate of electric energy for most commonly used electric light sources, there are stroboscopic and stroboscopic effects, and the lighting quality is not high, resulting in waste of precious energy
