  • Patent number: 7290906
    Abstract: A lamp can include LED lamps as a light source. An optical guide path including a first reflecting surface and a second reflecting surface can be provided between the LED lamp and a lens that radiates an illumination light. The optical guide path can be integrally composed of a high-refractivity material. Thus, the light passing through the optical guide path can more efficiently reach the lens. In addition, the integral optical guide path requires less assembly and thus can improve accuracy of assembly and can possibly result in a large gain in the amount of light emitted from the lamp.

  • Patent number: 6464539
    Abstract: A lamp fitting structure having a small depth dimension can include a socket for fixing a wedge-base lamp. The socket can include an insertion portion for receiving and fitting a fixed portion of the lamp therein, a peripheral portion and a rear end portion on the back face, all integrally formed. An opening can be provided which penetrates through from the insertion portion to the rear end portion. The socket does not require an electrical feed terminal for electrical connection, and only performs fixation of the inserted lamp A connector can be fitted into the opening in the rear end portion, for electrically connecting the feed terminal disposed in the connector to a lead wire of the wedge-base lamp. By inserting and fitting the connector into the socket from the rear end portion thereof the fixation between the wedge-base lamp and the socket can be made more secure.
