摘要： A lighting device may be provided that includes: a first to a fourth light emitting devices which are disposed on a substrate a first and a second pulse width modulation controllers which perform a pulse width modulation on currents applied to the first and the second light emitting devices respectively; and a first and a second controllers which control respectively currents applied to the third and the fourth light emitting devices having color temperatures different from those of the first and the second light emitting devices, wherein an (x, y) coordinate, which is determined by the mixture of the lights emitted from the first to the fourth light emitting devices and is located within a 1931 CIE chromaticity diagram, is moved onto a black body radiation curve within the 1931 CIE chromaticity diagram through the pulse width modulation of the first and the second pulse width modulation controllers and the control of the first and the second controllers.

摘要： A lighting device may include a heat sink and a mounting surface provided a prescribed distance over the heat sink. A plurality of light emitting diodes may be provided on the mounting surface. The plurality of light emitting diodes may be positioned a prescribed distance from a point on the mounting surface. An enclosure having a prescribed shape may be provided over the mounting surface and the plurality of light emitting diodes. The enclosure may include luminescent material such that a wavelength of light emitted by the enclosure is different from a wavelength of light emitted by the plurality of light emitting diodes. A bulb may be provided over the heat sink to surround the enclosure.
