摘要： A heat-dissipation car lamp includes a lamp housing and a light source module. The lamp housing is provided with a heat dissipation cavity, an air inlet, and an air outlet. An inside of the heat dissipation cavity is provided with a heat-dissipation fin clinging to a first heat-conducting plate, which is connected to the light source module. The air inlet is provided with a fan fitting the air inlet. The heat-dissipation fin and the first heat-conducting plate seal the interior of the lamp housing. A one-way independent heat-dissipation flow channel is formed through the air inlet, heat dissipation cavity, and air outlet. The air is driven by the fan to flow rapidly through the heat-dissipation fin and exit from the air outlet, and a large amount of heat is carried away, such that the fin is rapidly cooled after absorbing the heat emitted from the light source module.

摘要： A lighting fixture for a vehicle efficiently releases heat from a light source while inhibiting moisture from entering the light source side. The lighting fixture includes: a light source; a heat dissipating member which dissipates heat from the light source, the light source being placed on an installation surface of the heat dissipating member; and a socket to which the heat dissipating member is attached. The heat dissipating member has a heat dissipating fin part protruding from a heat dissipating surface on the side opposite to the installation surface, and a heat dissipating-side positioning part (positioning projection) provided on the heat dissipating surface. The socket has, on an attachment surface, a fin recess into which the heat dissipating fin part fits, and a socket-side positioning part (positioning hole) which determines the positional relationship between the heat dissipating member and the socket in cooperation with the heat dissipating-side positioning part.

摘要： A headlight apparatus includes a high beam headlight and a low beam headlight, which includes: an LED; an LED collimator that is a light source condensing optical system configured to condense a light emitted from the LED; a light guide that is a light distribution controlling light guide, a light from the LED collimator entering the light guide; and a projector lens that a light from the light guide enters, the projector lens being configured to project a light. The light guide includes an incident surface, a plurality of total reflection surfaces, and an emission surface. A first light of an incident light from the incident surface is emitted from the emission surface without reaching the plurality of total reflection surfaces, and a second light of the incident light is emitted from the emission surface via multiple times of total reflection by the plurality of total reflection surfaces.

摘要： An apparatus includes an auxiliary light includes a housing defining a front opening, a light emitting in the housing, and a transparent cover is mounted over the front opening. A plurality of fins are mounted to the housing and extend rearwardly from the front opening. The heights of the plurality of fins in the vertical direction decreases with distance from the front opening along the horizontal direction. This may include downward sloping outer fins and inner fins having bottom edges that include concave arcs extending upwardly. A mount secures to the housing and includes a base with a fastener overlapping a center of gravity of the light and arms that extend up to pivot points on the housing that are offset behind the center of gravity.

摘要： The subject of the invention is a reflector device for a lighting module of a motor vehicle. The device includes a housing made of plastic, wherein the internal faces are metallized so as to reflect the light received. The housing on an external face of one of its walls has reception means able to house a support including at least one light source, the wall having an opening which leads toward the inside of the housing and which allows the light emitted by the light source or sources to propagate toward the inside of the housing. According to the provisions of the invention, the external face of the housing may be connected to ground potential so as to act as a shield against the electromagnetic waves emitted by various electronic components.
