<p>PURPOSE: An illuminating apparatus is provided to control brightness regardless of a minimum driving current by compensating various colors and brightness of the lighting electrically. CONSTITUTION: A lighting application includes a first converter, a controller(100), a first driving part, and a guide unit(210). The first converters is one of N converters(170) applying a DC power to a first lighting element of N lighting elements. The controller outputs N PFM signals corresponding to N lighting elements according to a command signal. A first driving unit is one of N driving units(160) controlling the DC power supplied to the first converter corresponding to the first PFM signal. A guide mixes monochromatic lights emitted from the N lighting elements and radiates illumination.</p> |
