Abstract
A light emitting device includes a first light source unit and a second light source unit that emit three or more types of laser light beams having wavelengths different from each other, a light guide portion in which the laser light beams emitted from both the first light source unit and the second light source unit are guided, and a first heat sink and a second heat sink that respectively hold the first light source unit and the second light source unit at predetermined positions, and dissipate heat generated from the first light source unit and the second light source unit.
Claims14
A light emitting device comprising:
- at least one light source unit that emits three or more types of laser light beams having wavelengths different from each other;
- a light guide portion in which the laser light beams are guided;
- and
- a heat dissipating member that holds the light source unit and the light guide portion at predetermined positions, and dissipates heat generated from the light source unit.
A liquid crystal display device comprising:
- a light emitting device as a backlight, the light emitting device including
- at least one light source unit that emits three or more types of laser light beams having wavelengths different from each other,
- a light guide portion in which the laser light beams are guided, and
- a heat dissipating member that holds the light source unit and the light guide portion at predetermined positions, and dissipates heat generated from the light source unit.
