  • Patent number: 10400970
    Abstract: A vehicle front lamp that emits light forward includes a first light emitter that emits first emission light having a correlated color temperature of at least 3000 K and at most 7000 K, and a second light emitter that emits second emission light having a correlated color temperature of at least 3000 K and at most 7000 K. The chroma value of the first emission light is lower than the chroma value of the second emission light. The chroma value of each of the first emission light and the second emission light is derived by using the calculation method stipulated in The CIE 1997 Interim Color Appearance Model (Simple Version). The second emission light is emitted far ahead and the first emission light is emitted onto a road surface ahead, when the vehicle front lamp is mounted on a vehicle.

  • Patent number: 9057495
    Abstract: An illuminating lamp and a vehicle head lamp, using a light emitting diode, respectively, are capable of not only keeping the same brightness as obtained at the time of lighting after many hours from the lighting, but also being usable for many hours without deterioration in efficiency besides advantages of providing a high output in low power consumption, a long service life, and a simple structure. The illuminating lamp comprises a light source support made up of an upper structure and a lower structure, the upper structure being linked with the lower structure via the heat conduction bar, wherein the light source support is inserted into an aluminum heat-release mount, thereby causing heat generated from the light emitting diode to be released into the aluminum heat-release mount through cooling of the heat conduction bar.

  • Patent number: 8939623
    Abstract: Disclosed is a projection lens that is disposed in front of a first semiconductor light emitting device and configured to irradiate light incident from the rear side to the front side. A first reflector reflects a part of the light emitted from the first semiconductor light emitting device to converge on the rear side of the projection lens. A light guide member is disposed across the front side of the projection lens and configured to emit the light incident from the second semiconductor light emitting device to a predetermined direction. A second reflector reflects a part of the light reflected by the first reflector toward the projection lens. The light reflected by the second reflector to be incident on the projection lens is emitted from the projection to avoid the light guide member.
