  • Vehicle lighting device using led light source
    Patent number: 6530683
    Abstract: A vehicle lighting device has a housing, a plurality of light guides extending in radial fashion from the substantially center part of the housing, a reflector within the housing, and a plurality of LED light sources. The surface of each light guide has a reflective region with a reflecting means along the longitudinal direction thereof and an transmissive region in which the reflecting means is not provided. The transmissive region faces forward, and the reflective region faces rearward. The reflector is disposed further to the rear than the light guides, and in opposition to the reflective regions. Each LED light source is in proximity to one end of a light guide.

  • Small light-source module and light-source unit
    Patent number: 6474852
    Abstract: A small light-source module has a module body having a small single-point light source with a limited light-emitting angle mounted thereto, and a reflective surface provided on the module body. The light axis of the light source tilted with respect to the reflective surface, so as to create a substantially fan-shape projected light region on the reflective surface. The outer contour of the reflective surface is also substantially fan-shaped, and the reflective surface has a reflective pattern for reflecting light emitted form the small single-point light source as parallel light.

  • Light emitting diode mounting structure
    Patent number: 6386733
    Abstract: A light emitting diode mounting structure for a light emitting diode having four leads has two metal plates fixed to wire on a housing. The leads engage the metal plates in electrical contact therewith and are supported by the metal plates, a surface part of which reflects light from the light emitting diode.
