Vehicle lamp

Abstract

The invention provides a vehicle lamp, comprising a light-emitting array which comprises a first light-emitting sub-array and a second light-emitting sub-array which can be switched on and off independently; a projection lens, arranged on an emergent light path of the light-emitting array, the distance between the light-emitting array and the projection lens being larger than the focal length of the projection lens, and the second light-emitting sub-array at least comprising a light-emitting element arranged on the optical axis of the projection lens; a shading device, comprising a shading surface, the shading surface being obliquely arranged between the first light-emitting sub-array and the second light-emitting sub-array relative to the plane where the light-emitting array is located, and the shading surface inclining towards the second light-emitting sub-array. The shading surface comprises a first area far away from the light-emitting array. The first area is located on the frontfocal plane and the optical axis of the projection lens, and the first area comprises a low beam cut-off line contour. According to the vehicle lamp, high beam and low beam integrated automobile lampillumination which is free of bright and dark lines, clear in low beam cut-off line and high in center brightness is achieved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a vehicle lamp. Background technique [0002] Since the advent of LED car headlights in 2007, car headlights have gradually transitioned from halogen lamps and xenon lamps to LED lights. Especially in recent years, with the majestic development of new energy vehicles, LED lights have entered a stage of blowout development. LED car lights have the advantages of long life, low energy consumption and low cost compared with xenon lamps, and gradually cover from high-end cars to low-end cars. [0003] Existing LED car lights generally adopt the design idea of ​​the original halogen lamp, especially the far and near integrated headlight. This technical solution usually uses a high-brightness LED as the luminous center to replace the original halogen filament, and then collects the emitted light of the LED through a reflector, so that the emitted light of the LED converges at the hot...
