摘要： The disclosed subject matter can include a vehicle lamp having a favorable light distribution and an effective heat dissipation structure. The vehicle lamp can include a light source and a casing in which the light source is sealed. The casing can be configured in a tubular shape and a reflector can be configured in a hollow of the casing. The casing can be sealed between the reflector and a front lens configured to allow light emitted from the light source to pass therethrough. The inner surfaces of the casing and the reflector can be configured to form a predetermined light distribution via the front lens. The outer surfaces of the casing and the reflector can be exposed to the outside and can be configured to radiate heat generated from the light source to the outside using heat conductive material. Thus, the lamp can be miniaturized and provide favorable light distribution.

摘要： A vehicle light can simultaneously form a light distribution pattern for a tail/stop lamp in one direction and another light distribution pattern for a side marker lamp in another direction without use of a dedicated light source(s). The vehicle light can include: a cover lens having a lens portion and a wraparound lens portion extending from the lens portion to the vehicle side face; a first LED light source configured to form first and second light distribution patterns; and a first reflector configured to reflect a first part of light from the first LED light source so as to form the second light distribution pattern. The first LED light source can be disposed so that a second part of the light from the first LED light source passes through the wraparound lens portion to form the first light distribution pattern. The first reflector can be disposed between the first LED light source and the wraparound lens portion so that the first reflector does not block the second part of the light.

摘要： A lamp unit is constructed of light sources, a reflector, a lamp housing that receives the light sources and the reflector therein, and a lamp lens that closes an opening of the lamp housing. The reflector has a through hole that is formed in a portion positioned above a first light source as a heat source, so that air warmed by heat of the first light source can be introduced into a rear side of the reflector via the through hole. The air introduced into the rear side of the reflector via the through hole and ascending therein can be lead by a first guide means to an air stagnating portion positioned in an end periphery of a hermetically-closed space that is defined by the lamp housing and the lamp lens.
