Abstract: A vehicle lighting unit with a bulb fixation structure is configured such that a metal supporter spring is attached to an opening end face of a holder projected from a peripheral edge of a bulb attachment hole opened in a reflector, engagement claws provided to the bulb pass through respective claw escape holes formed in the supporter spring so that the bulb is incorporated within the holder, and then the bulb is rotated. Thereby, the bulb is fixed to the main body with a type of a bayonet scheme in which the engagement claws of the bulb are interposed in between and held by the engagement spring of the supporter spring and an opening end face of the bulb attachment hole. The supporter spring is attached to the opening end face of the holder by countersunk screws at at least three locations in a circumferential direction of the supporter spring.

Abstract: A vehicle position lamp can include a plurality of circuit boards each mounting an LED. The vehicle position lamp can also include a first inner lens having a plurality of optical plates and at least one connecting plate connecting between the adjacent optical plates and a second inner lens. An inner surface of each of the optical plates can be located adjacent the respective one of the circuit boards so that an optical axis of a diffusing lens of each of the optical plates corresponds to a substantially optical axis of each of the LEDs. The second inner lens can be located adjacent the first inner lens that can be formed in various slender curved shapes. Thus, the disclosed subject matter can provide vehicle position lamps having a high visibility that are formed in various slender curved shapes such that match headlights, which fit both front corners of a vehicle.

Abstract: A vehicle light is provided which can prevent the accumulation of assembly errors during the assembling of separate optical components. The vehicle light can include a first heat sink having a first heat sink body and a first heat radiation fin, and a first optical system configured to form a part of a predetermined light distribution pattern. The first optical system can include a first LED light source, a first reflector configured to reflect light emitted from the first LED light source, and a projection lens configured to allow light reflected from the first reflector to pass therethrough. The first LED light source, the first reflector, and the projection lens can be secured to an upper surface of the first heat sink body.

Abstract: A light can be configured by assembling an additional optical system in a lower optical system in a period of time that can be shorter than that of the conventional case. The vehicle light can include a first optical system configured to form a part of a predetermined light distribution pattern, and a second optical system disposed adjacent to the first optical system and configured to form a part of the predetermined light distribution pattern. The second optical system can include a light source, and a reflector including a first reflecting surface, a second reflecting surface, and a third reflecting surface. The reflector can be integrally formed with the first reflecting surface, the second reflecting surface, and the third reflecting surface.

Abstract: A light can be configured by assembling an additional optical system in a lower optical system in a period of time that can be shorter than that of the conventional case. In addition to this, accumulation of assembly errors can be avoided during the assembling of these optical systems. The vehicle light can include a first optical system configured to form a part of a predetermined light distribution pattern, and a second optical system disposed adjacent to the first optical system and configured to form a part of the predetermined light distribution pattern. The second optical system can include a light source, and a reflector including a first reflecting surface, a second reflecting surface, and a third reflecting surface. The first reflecting surface can be disposed in the light emitting direction of the light source, and the first reflecting surface can reflect light emitted from the light source to a predefined illuminating direction, for forming a part of the predetermined light distribution pattern.
