Xenon light source lens automobile lamp manufactured through BMC (bulk molding compound)

Abstract

The invention relates to a xenon light source lens automobile lamp manufactured through BMC (bulk molding compound). The xenon light source lens automobile lamp comprises a lampholder, a light source and a lens, wherein the lampholder is manufactured through a BMC material; a hyperbolic reflecting surface is arranged in the lampholder; the light source is arranged in the center of the reflecting surface; the lens is arranged in front of the light source; a reflective layer is arranged on the surface of the reflecting surface; the lampholder is an integrated structure formed through injection molding; the automobile lamp is provided with a light adjusting plate; and the light source of the automobile lamp is a xenon light source. Compared with the prior art, the xenon light source lens automobile lamp has the advantages that the BMC formula is optimized, and when the BMC material is utilized in the automobile lamp, the heat resistant temperature of the automobile lamp can be increased by 100 degrees compared with the heat resistant temperature of conventional automobile lamps; the utilization requirement of an HID (high density discharge) lampholder can be met; a traditional BMC injection machine and a traditional mold can be utilized, so that the cost is reduced, and the transformation progress from a halogen lamp to an HID lamp is improved; and the heat resistant temperature of the automobile lamp lampholder is increased from 220 degrees to 320 degrees, and the requirement of the lampholder on long-term normal operation at a relatively high environment temperature can be met.

Description

technical field [0001] The invention relates to the technical field of vehicle lights, in particular to a xenon light source lens vehicle light made of BMC material. Background technique [0002] BMC (Bulk Molding Compound), also known as bulk molding compound, is a mass combination obtained by fully kneading and kneading unsaturated polyester resin, reinforcing material, curing agent, mold release agent, low shrinkage agent and other filling materials. things. BMC is a thermosetting plastic. BMC has good dimensional accuracy, good heat resistance and excellent insulation performance, so it is widely used in motor plastic packaging, automotive parts, circuit breakers and precision parts molding. Since the 1980s abroad, the headlight reflectors of automobiles have begun to use BMC materials. [0003] At present, the lighting system of automobile headlights generally includes a lamp holder and a light source. The light source mainly includes a halogen light source and a xeno...
