LIGHTING EMITTING APPARATUS AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: A light generating apparatus and control method thereof are capable of preventing non-uniformity in an LED manufacturing process by realizing a precise wavelength control function of sensing a temperature of LED module. CONSTITUTION: A LED module (160) is arranged in a form that one or more LED types for at least one light emitting mode are integrated. A memory (130) stores an intrinsic current value of each LED. A LED module driving unit (150) emits the LED module. A calculation processing unit (120) identifies a set light emitting mode and then outputs a synthetic wavelength by identifying the intrinsic current value of each LED in the memory and by compensating the output LED peak wavelengths. The synthetic wavelength is output as a driving current value by being output as a first correction current value in comparison with a desired peak wavelength of light emitting mode. The driving current value is transmitted to the LED module driving unit to emit the LED according to the light emitting mode in the LEDs mounted in the LED module.
