  • Publication number: 20060098450
    Abstract: A reflector is constructed by arranging two first reflecting surfaces. The two first reflecting surfaces are arranged by making first focal points F1 of the first reflecting surfaces be alienated from each other, centering on the optical axis Z within an area of an effective diameter R of a convex lens, and making second focal points F2 thereof gradually come close to each other so as to be located inside the two first focal points F1. An LED is formed of two LEDs respectively arranged near the first focal positions, with light emitting points F1 thereof facing one of the two first reflecting surfaces. The obtained light distribution pattern has double quantity of light, and does not have a non-emission part inside thereof, and the combined light of the two LEDs can solve a problem of color irregularity.

  • Publication number: 20050259431
    Abstract: A headlamp unit for a vehicle comprises two LEDs, two sub-reflectors, a main reflector and a convex lens. The sub-reflector reflects light emitted by the LED and has a reflective surface and an opening. The reflective surface is a part of an ellipsoid of revolution having a first focus position located to the LED and a second focus position located on an upper side of an optical axis. The opening is formed on an upper portion of the sub-reflector so as to substantially coincide with a horizontal plane including the optical axis. The main reflector is disposed so as to be opposed to the sub-reflectors and reflects light reflected by the sub-reflectors. The convex lens forward outputs light reflected by the main reflector to present a desired light distribution pattern.

  • Patent number: 6134692
    Abstract: A control unit transmits address area designation information designating an arbitrary bit position in ID data. At least a response unit transmits a response signal with an error detection code attached to predetermined information in the unique information held in itself by means of a time slot determined by the address area designation information and the ID data of the particular response unit. The control unit checks for the presence or absence of an error of the information in each time that has arrived, fetches only the response signal free of error, and transmits the error presence-absence information indicating the inspection result. Further, in the case where there exists a time slot having an error, the control unit transmits new address area designation information.
