Disclosed is a light emitting device, and more particularly are a light emitting device package configured to improve the quality of light and a lighting apparatus using the same. The light emitting device package includes a light emitting device located on a package main body, the light emitting device including a first light emitting device configured to emit light having a first wavelength band and a second light emitting device configured to emit light having a second wavelength band, a lens disposed over the light emitting device, and a wavelength conversion layer disposed over the lens, the wavelength conversion layer serving to absorb light having the first wavelength band or the second wavelength band so as to emit light having a third wavelength band.

Light emitting device package and lighting apparatus using the same

A light emitting device is provided. The light emitting device includes a first white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.4822, 0.3980); a second white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.4180, 0.4337); and a third white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.2806, 0.2981).

Light emitting device

A light emitting device is provided. The light emitting device includes a blue light emitting diode (LED); and phosphors including first to third phosphors, wherein the first phosphor is excited by light emitted from the blue LED, emits light having a main wavelength of about 495 nm to about 510 nm, and includes BaSiON:Eu or (Ba,Sr)SiON:Eu where 0&#x3c;x&#x3c;1, the second phosphor is excited by light emitted from the blue LED, emits light having a main wavelength of about 555 nm to about 575 nm, and includes LuAlO:Ce or (Lu,Gd)AlO:Ce where 0&#x3c;x&#x3c;1, and the third phosphor is excited by light emitted from the blue LED, emits light having a main wavelength of about 580 nm to about 605 nm, and includes (Ca,Sr)AlSiN:Eu where 0&#x3c;x&#x3c;1.

High color rendering light emitting device including different phosphors

A light emitting diode (LED) based lamp is provided that may include a housing, a LED module having at least one LED to emit light, and a lens to receive the light from the LED and to guide the light to a specific area. An outer circumference of the lens may have a different surface roughness than an inner surface of the lens or may have a different light transmissivity than the inner surface of the lens. The outer circumference of the lens may minimize light from being transmitted to a region outside the specific area.

LED based lamp and method for manufacturing the same

A light emitting diode (LED) based lamp may include a LED module having at least one LED to provide light, a housing to house the LED module, and a lens to receive the light from the LED and to direct the light in a specific direction. A microlens array may have a plurality of microlenses with a polygonal shape, and a distance between two opposing sides of one of the microlens is 0.7 mm to 1.2 mm.
