  • Publication number: 20150009694
    Abstract: To provide a technique capable of achieving AFS control without using mechanical means. A vehicle headlamp for forming a low beam that illuminates a relatively lower region of a space in front of a vehicle, including a first light source apparatus for forming a first irradiating light, a second light source apparatus for forming a second irradiating light with a width in the up-down direction that is smaller than that of the first irradiating light on an upper end side of the first irradiating light, and a lens that projects the light emitted from the first light source apparatus and the second light source apparatus, respectively, wherein the second light source apparatus includes a first light-emitting device array that extends in a first direction, and the first light-emitting device array includes a plurality of light-emitting devices capable of being individually turned on and off, arranged along the first direction.

  • Publication number: 20150009693
    Abstract: A light source apparatus having a plurality of light-emitting device arrays, each extending in a first direction and adjacently disposed in a second direction that crosses the first direction is disclosed. Each of the plurality of light-emitting device arrays comprises a plurality of light-emitting devices arranged along the first direction and is the same in length. Among the plurality of light-emitting device arrays, the number of the respective light-emitting devices of a first light-emitting device array at one end in a second direction is smaller than the number of the respective light-emitting devices of a second light-emitting device array adjacent to the first light-emitting device array. The surface area of the light-emitting units of the respective light-emitting devices of the first light-emitting device array is larger than that of the light-emitting units of the respective light-emitting devices of the second light-emitting device array adjacent to the first light-emitting device array.

  • Patent number: 8870423
    Abstract: A vehicle decorative lighting device and a vehicle lamp including a lighting device can include a light guide lens formed in a substantially U-shape and a pair of LED light sources that can emit various color lights. Each of the light sources can be located at both end surfaces of the light guide lens having a U-shaped light-emitting surface. The vehicle lamp can include a lamp room between an outer lens and a housing, and can incorporate various vehicle lamps such as a headlight along with the lighting device in the lamp room. The lighting device can be located in the lamp room so as to emit various U-shaped color lights along a periphery of the outer lens. Thus, the disclosed subject matter can include providing vehicle lamps including the decorative lighting device having a harmonious favorable light distribution, for example, such that combine a headlight with a position lamp.

  • Patent number: 8393769
    Abstract: A projector headlight for a low beam can include a light source, an ellipsoidal reflector, a projector lens and a shade. Light emitted from the light source can form a fundamental light distribution pattern from the projector lens via the ellipsoidal reflector by shielding an upward portion of the light with the shade. The shade can form a blurred part on a horizontal cut-off line using a radiused R surface between a top and front edge lines of the shade. Therefore, a contrasting difference between the upper and lower sides of the horizontal cut-off line can be reduced so as to be able to conform to a light distribution standard for a headlight. The R surface can be configured with a reflex surface or a non-reflex surface to match the light source. Thus, the projector headlight can perform a favorable light distribution pattern utilizing a simple structure.

  • Patent number: 5291661
    Abstract: A peephole for a built-in lighting fixture type aiming device. A frame portion projected on an edge portion of an opening portion is formed on the side thereof with an engaging groove, a frame type hook plate is placed in contact with the peripheral edge of a window glass by a spring member and engaged by a hook with the engaging groove provided in the frame portion, and a seal gasket is held by the frame portion and the window glass with the aid of elasticity of the frame type hook plate to provide an airtight construction. The window glass is mounted by the frame type hook plate avoiding the need for a threaded mounting.
