Electronic ballast with power control for steam and metal halide lamps sõdio

摘要

"Electronic ballast with power control for sodium vapor and metal halide lamps", describes the present patent as a practical,Modern and efficient electronic ballast in the solid state power control on the luminous flux of sodium vapor and metal halide lamps with power of 70 W and cent and cinqu00fcenta watts for application in public lighting in general.More specifically, a refinement to the electronic ballast for metal halide lamps sodium vapor and the inventor and the depositor.The patent in question comes to innovate with a control power to the lamps sodium vapor and metal halide.That keeps stable power on the lamp throughout the operating cycle, enabling the luminous flux to be constant throughout its useful life.The electronic ballasts have high power factor, high efficiency and working in high frequency, reduces the wear of the electrodes and increases the useful life of the lamp.
