Abstract:
PURPOSE: An LED base and an LED module using the same are provided to form a light distribution angle of a lighting device by controlling the light radiation range of an LED according to the position of the LED base on a printed circuit board. CONSTITUTION: An LED base(100) comprises a pair of sidewall bodies and a connection body. The connection body connects the pair of sidewall bodies. The upper side with an LED is positioned on the bottom of the upper side of the sidewall body and is inclined with a preset angle. The inner sidewalls(114) of the pair of sidewall bodies are widened along the upward of the sidewall body. The inner sidewalls of the pair of sidewalls are linear or curved.
Abstract:
PURPOSE: An LED package and a lighting device are provided to implement light with various colors by controlling the intensity of sub light. CONSTITUTION: A main optical source module(100) emits main light of a single color. A sub optical source module(200) emits sub light. A color control unit(300) controls a color of the sub light. A sub light intensity control unit(400) controls the intensity of light from a sub optical source. A power source unit(500) supplies power to a sub optical source module(200).
Abstract:
PURPOSE: An LED device and a color temperature controlling method thereof are provided to simplify a structure by comprising a main light source and a sub light source as one module. CONSTITUTION: An LED module(120) includes a main light source(121) with a white LED and a sub light source(122) with a blue LED. The LED module includes a reflection plate(160) which reflects light to irradiate an approaching surface. A lens concentrates light from the LED module on the approaching surface. A heat sink discharges heat from the main light source and the sub light source to the outside. An optical fiber mixes the white light of the main light source with the blue light of the sub light source and sends the mixed light to the lens.
