Abstract
A flash LED package includes a substrate; a flash LED device in a first region of an upper surface of the substrate, and including first to fourth LED light sources that emit white light, blue light, green light, and red light, respectively; an optical sensor in a second region of the upper surface of the substrate, and having a light receiving region that detects a correlated color temperature; and a lens cover on the substrate to cover the flash LED device and the optical sensor, and having a lens unit in a region overlapping the first to fourth LED light sources.
Claims16
A flash LED package, comprising:
- a substrate;
- a flash LED device in a first region of an upper surface of the substrate, and including first to fourth LED light sources that emit white light, blue light, green light, and red light, respectively;
- an optical sensor in a second region of the upper surface of the substrate, and having a light receiving region that detects a correlated color temperature;
- and
- a lens cover on the substrate to cover the flash LED device and the optical sensor, and having a lens unit in a region overlapping the first to fourth LED light sources,
- wherein the first to fourth LED light sources have three or more different areas, and
- wherein the first LED light source emits white light having a color temperature of 2000K to 5500K and a color rendering index of 80 or higher.
A flash LED package, comprising:
- a substrate;
- a flash LED device on an upper surface of the substrate, the flash LED device including first to fourth LED light sources that emit white light, blue light, green light, and red light, respectively, and having side surfaces surrounded by a reflective structure;
- and
- a lens cover on the substrate, the lens cover having an upper surface having a lens unit in a region overlapping the first to fourth LED light sources, and having a lower surface facing the flash LED device,
- wherein the first to fourth LED light sources have three or more different areas, and
- wherein the first LED light source emits white light having a color temperature of 2000K to 5500K and a color rendering index of 80 or higher.
A flash LED package, comprising:
- a substrate;
- a flash LED device in a first region of an upper surface of the substrate, and including first to fourth LED light sources that emit white light, blue light, green light, and red light, respectively;
- an optical sensor in a second region of the upper surface of the substrate, and having a light receiving region that detects a correlated color temperature of incident light;
- a lens cover on the substrate to cover the flash LED device and the optical sensor, and having a lens unit in a region overlapping the first to fourth LED light sources;
- and
- a control unit that applies a driving power value corresponding to a value of the correlated color temperature detected by the optical sensor to the first to fourth LED light sources with reference to a previously-stored look-up table to control the correlated color temperature of light emitted from the flash LED device,
- wherein the first to fourth LED light sources have three or more different areas, and
- wherein the first LED light source emits white light having a color temperature of 2000K to 5500K and a color rendering index of 80 or higher.
