Abstract
A light emitting device package includes a package body; a first light emitting device mounted on the package body and emitting light of a particular color; a second light emitting device mounted on the package body to be adjacent to the first light emitting device, adjusting an amount of light according to a current value applied thereto to thereby control a color temperature, and emitting orange light; and a resin part sealing the first and second light emitting devices and containing at least one or more types of phosphors.
Claims14
A light emitting device module comprising:
- a light emitting device package including:
- a package body;
- a first light emitting device mounted on the package body and emitting light of a particular color having a peak wavelength corresponding thereto;
- a second light emitting device mounted on the package body to be adjacent to the first light emitting device, adjusting an amount of light according to a current value of a driving power applied thereto to thereby control a color temperature, and emitting orange light;
- and
- a resin part sealing the first and second light emitting devices and containing at least one or more types of phosphors;
- and
- a drive control unit controlling the light emitting device package, the drive control unit including:
- a first driving circuit adjusting a current value applied to the first light emitting device according to an external control signal to thereby alter a color temperature;
- and
- a second driving circuit adjusting a current value applied to the second light emitting device according to an external control signal to thereby alter a color temperature.

A surface light source device comprising:
- a substrate having a plurality of white light emitting device packages and one or more orange light emitting device packages arrayed thereon;
- and
- a drive control unit including a first driving circuit adjusting a current value applied to the white light emitting device packages according to an external control signal to thereby alter a color temperature and a second driving circuit adjusting a current value applied to the orange light emitting device packages according to an external control signal to thereby alter a color temperature,
- wherein the white light emitting device packages and the orange light emitting device packages are electrically connected to respective light emitting device packages of the same color.
