Japanese Patent JP5227674

B2

A lighting device with a stable high light intensity can effectively dissipate heat generated by an LED so that the light emission efficiency does not deteriorate while the inside temperature distribution can be maintained in an even state. The lighting device can also be configured to prevent snow from adhering onto an outer lens by allowing an outer surface temperature of the lighting device to rise during actuation of the device. The lighting device can also be configured to improve light utilization efficiency. The lighting device can include a semiconductor light emitting device as a light source and can include structure(s) that guides the emission light to a projection lens. The semiconductor light emitting device can be configured to emit light in a reverse or opposed direction with respect to an illumination direction for the lighting device. A projection lens can be disposed in front of the semiconductor light emitting device. An elliptic reflector can be configured to reflect light from the semiconductor light emitting device and to direct the light to the projection lens. A lens holder can be made of metal and the semiconductor light emitting device and the projection lens can be disposed on the lens holder.
