摘要:
A sealing structure using a liquid gasket, having a liquid gasket interposed in the form of a thin film between mating surfaces of a first member and a second member, thereby preventing the movement of oil via the mating surfaces, the sealing structure, includes at oil-side end portions of the mating surfaces, a gasket lump portion that is formed of an excess of the thin-film liquid gasket squeezed out from the mating surfaces, and an oil-shielding portion that covers a boundary portion where the gasket lump portion and the first member come into contact, thereby preventing a flow of the oil from directly striking the boundary portion, and is provided on an oil-flow upstream side from the boundary portion.

There is provided a vehicle lamp. The vehicle lamp includes a lamp body including a hole portion therein; an outer lens, attached to the lamp body to form a lamp chamber; a lamp unit provided in the lamp chamber and including a light emitting element serving as a light source; a heat sink; and a fan. The heat sink includes a base portion fitted into the hole portion of the lamp body; outer fins disposed on a surface of the base portion and extending outside of the lamp body; and inner fins disposed on another surface of the base portion and extending into the lamp chamber. The fan moves air in the lamp chamber toward the inner fins, which are configured such that the air passing between the respective inner fins is guided toward the outer lens.

An automotive lamp includes a semiconductor light emitting device used as a light source and bracket used as a support member supporting the semiconductor light emitting device. The bracket includes a first heat-transfer member having an isotropic thermal conductivity in at least part of region in contact with the semiconductor light emitting device, and a second heat-transfer member having an anisotropic thermal conductivity in a region in contact with the first heat-transfer member.

A vehicle lamp is provided with a plurality of lamp units respectively including light sources, and optical units for emitting light from the light sources ahead of the lamp unit, and a driving unit configured to swivel the plurality of optical units in different strokes.
摘要:
In a vehicular lamp in which a light source unit that includes an LED as a light source and an optical element is attached to a heat sink, and an LED module in which the LED is mounted to a power supply substrate is pressed against and fixed to a substrate mounting surface of the heat sink via an attachment, a plurality of positioning protrusions that abut an outside edge of the power supply substrate are provided around the substrate mounting surface, and a groove that extends along an outer peripheral surface of each protrusion is provided on at least a side of a base of the protrusion, the side of the base facing the substrate mounting surface.
