Abstract

The invention relates to a lamp cap, a motor vehicle lighting device and a motor vehicle. The lamp cap comprises a heat conduction mounting plate, a heat conduction connecting plate, a heat conductionpipe sleeve, a control circuit board, a switching circuit board, lamp boards and a heat dissipation module. The heat conduction mounting plate is connected with the heat conduction pipe sleeve through the heat conduction connecting plate. The control circuit board is arranged in the heat conduction pipe sleeve, and is connected with the end portions of the lamp boards through the switching circuit board. The two lamp boards are arranged on the two side surfaces of the heat conduction mounting plate correspondingly. When the heat dissipation module works, because the heat dissipation module isrelatively close to a lamp bead and the lamp boards, heat of the lamp boards can be better diffused to the outside, the lamp cap has a better heat dissipation effect, the light attenuation speed canbe reduced, and the service life can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular to a lamp holder, a motor vehicle lighting device and a motor vehicle. Background technique [0002] LED lamp is a new green lighting high-tech industry, especially LED light source has the characteristics of green environmental protection, high brightness, high efficiency and energy saving, and LED lamp is used as a cold light source, its temperature is lower than that of halogen lamp and xenon lamp, which prolongs the service life. A traditional motor vehicle lighting device includes a lamp cap with an LED lamp, a reflective bowl and a protective shell. The reflective bowl is installed inside the protective shell. Located outside the protective shell, the lamp holder relies on materials with better thermal conductivity to quickly diffuse the heat generated by the LED light source of the lamp holder outward. However, the heat dissipation effect of the car lights is still poo...
