Abstract
A lamp device is provided. The lamp device may include a substrate, a light emitting device provided on a first side of the substrate, a light guide having one end thereof optically connected to the light emitting device and a coupler binding the other end of the light guide, and a heat sink that is thermally connected to a second side of the substrate to radiate heat generated by the light emitting device.
Claims20
A lamp device, comprising:
- heat sink;
- a light source coupled to the heat sink, the light source including at least one light emitting diode (LED);
- a light guide having a first end thereof optically coupled to the light source and a second end thereof coupled to a plate having at least one opening formed therein so as to receive the second end of the light guide;
- and
- a first swivel frame received in a second swivel frame, the second swivel frame being received in a receiving body, wherein the heat sink, the light source, the light guide and the plate are all coupled to the receiving body such that the first and second swivel frames guide a direction of light emitted by the light source, and the heat sink dissipates heat generated by the light source.
