Pulsed RF .METHOD AND APPARATUS OF LIGHTING CONTROL USING THE PRE-DISTORTION AND PULSED RF CONTROL.

摘要

The present invention relates to a lighting control method and apparatus for the pre-distortion and Pulsed RF control precision to compensate for the light intensity control, particularly characteristic optical element relates to a lighting control method and apparatus using the same. The present invention is a plasma lamp unit for outputting a nonlinear optical power signal with a predetermined frequency; Light intensity of the optical output signal, the color temperature, the light output measuring unit which measures at least any one of the environmental temperature; Receiving feedback the measured signal of the output light measured by generating a predistortion signal for correcting the light output signal and generates a pre-distortion signal with a period of the bit sequence signal by the PWM control signals control processor for output to the plasma lamp; includes, measuring feedback of the signal, the optical output signal can be performed by the optical output signal and having a linearity error is repeated until a minimum. According to the invention, the surrounding environment, the temperature change over the signal processing control unit, the efficiency according to the characteristics change of the optical power loss and improve the non-linearity is calculated by analyzing and feeding back a relation between output optical measurement of the optical output signal and the optical properties precisely by using the pre-distortion has an advantage capable of generating an optical output.
