A vehicle lamp includes: a lamp body that has an opening in a direction of light radiation; a front cover that covers the opening to define a housing and includes, on an inner surface, an anti-fogging film mainly composed of a synthetic resin; a light source that is disposed in the housing; and a silicone resin part that is disposed in the housing. A content of D3 to D20 cyclic low molecular weight siloxanes in the silicone resin part is 0 ppm to 300 ppm in terms of mass.

An apparatus includes a light chamber defined by a lamp body and a front cover. The apparatus houses a projection-type light source unit which integrates a reflector, a light source disposed in the vicinity of a first focal point of the reflector, a convex lens disposed in front of the reflector, and an extension reflector. The convex lens is disposed such that light external from the lamp chamber enters the lamp chamber and is reflected out through the convex lens.

Vehicular headlamp with lens holder having upper opening portion

A vehicle headlamp including a reflector installed so as to be tiltable by an aiming mechanism installed in the lamp body. The aiming screw of the aiming mechanism has a rearward-extending portion that extends out of the lamp body, and a crown gear is attached to an area near the end of the rearward-extending portion so as to be spaced apart from a screw supporting wall of the lamp body that supports the middle portion of the aiming screw. An expanded-out wall that functions as a screwdriver guide for supporting a screwdriver that is used to rotate the crown gear is provided above the screw supporting wall. The end of the rearward-extending portion of the aiming screw is supported by a bracket that is installed near the screw supporting wall.

Reflector-movable headlamp

Chopped strands having a sizing agent impregnated on glass fiber strands, to be used for a molded product of unsaturated polyester resin BMC, wherein the sizing agent comprises a urethane resin, a vinyl acetate resin and a silane coupling agent, and wherein the mass ratio of the urethane resin to the vinyl acetate resin is from 30:70 to 70:30.

An object of the present invention is to prevent dazzlement from being caused by beams of light directly emitted from a light source, without requiring any bulky component member. A vehicular headlamp comprises a light source , a reflector , a cut-line forming shade for forming a cut line, and a condenser lens . The cut-line forming shade cuts off some beams of light emitted from the light source and reflected by the reflector and forms shaped beams of light. The condenser lens projects the shaped beams of light forwards and radiates them according to a light distribution pattern. An opening is formed between the condenser lens and the reflector. A dazzling-light cutting shade for cutting off beams of light emitted toward a region above the light distribution pattern is disposed between the light source and the opening.

Projection-type vehicular headlamp having reduced dazzling effect

A method for selectively oxidizing the primary hydroxyl group of an organic compound which comprises reacting a resin having an amine oxide adsorbed thereon and an electrolytically oxidized product of a halogen-containing compound with the organic compound having the primary hydroxyl group.
