Bifocal lens headlamp

Abstract

The invention provides a bifocal lens headlamp. The bifocal lens headlamp comprises a lens frame, a heat radiation frame, a back cover and a lamp head which are arranged in a linear mode, wherein a camera lens is put inside the lens frame; a lens is put in the camera lens; the two sides of the front end of the lens are of arc-shaped structures; the two sides use a 1-shaped center line as a symmetry axis, and are of a symmetrical structure; the lens frame passes through a lamp cover; one end of the lens frame is connected with the lamp cover through screw threads; the lamp cover is connected with the heat radiation frame through screw threads; an LED luminous lamp board is inserted and arranged in the heat radiation frame; a heat radiation fan is put in the heat radiation frame; the heat radiation frame is inserted and arranged at the inner side of the back cover; a circuit board is put in the back cover; the back cover is connected with the lamp head through a screw bolt; the LED luminous lamp board and the heat radiation fan are electrically connected with the circuit board; and an insertion rod for being connected with a power supply in a plug way is arranged on the lamp head. Anoriginal vehicle lamp is directly replaced without refitting circuits; the light form is in a 1 shape; the light spreading effect on streets is good; the brightness is uniform; the penetrability of the light rays under the conditions of rainy and foggy weather is high; and the visibility exceeds that of a conventional halogen lamp, a conventional xenon lamp and a conventional LED lamp.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a bifocal lens headlight. Background technique [0002] LED light source is a green light source with high efficiency, long life, fast response and strong shock resistance. LED lights are gradually used in car headlights, car tail lights, daytime running lights, indicator lights, etc. However, vehicles driving at night use low beams in most cases, and the frequency of use of low beams is far more than that of high beams. In the prior art, the circuit board of the LED automobile headlight is arranged vertically, and the lamp beads are installed on the left and right sides of the circuit board, which has the disadvantages of a long range of the low beam and a narrow width of the low beam and a small pavement area. At the same time, LED lights are generally white light. The low beam brightness of the existing LED car headlights is not high, and the penetrating power of ...

AI Technical Summary

Problems solved by technology

In the prior art, the circuit board of the LED car headlight is vertically arranged, and the lamp beads are installed on the left and right sides of the circuit board, which has the disadvantages of a relatively long low beam range and a narrow low beam width and a small paving area.

At the same time, LED lights are generally white light. The low beam brightness of the existing LED car headlights is not high, and the penetrating power of white light is not strong, which makes the low beam effect not good in rainy or smoggy days. When driving, you can hardly see the front clearly, and it is not easy to be spotted by the driver of the opposite vehicle when meeting, which poses a certain safety hazard
