Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device for discharging light using a variable frequency 1u path.

As a discharge lamp lighting device, a frequency variable circuit is used to set the operating frequency to 7i, which is known as a frequency lighting device.
:1 Lighting of light wave f) Luminous efficiency of light is 1'g/L,
1] Illumination by constant frequency VC is.

It is known that rice is also sieved with efficiency. [7 However, as a method to accommodate this 1 J-sized wave, the conventional method was to use a full-wave phase Ii current and a smoothed DC voltage with a frequency change.
This method VC kink is caused by a steep 9′ to the smoothing capacitor.
Completely revised 0 and 3 phase, which had the disadvantage that the input terminals were distorted due to the streetcar η smell! l! We will also discuss a method of directly changing the applied DC voltage, but with this method, the input current for all 11 phases,
Since the frequency of π/3 is missing in the cow cycle, the number of input terminals is still large, and noise due to I%itl of the input current (IIL voltage) and damage such as burnout of the power factor improvement conte/board are caused. VC is large enough to obtain a constant amplitude frequency.
I was heading south.

In addition, 1% brightness discharge has a phantom low frequency range (several tens of KHz).
