Problems solved by technology

Car headlights using traditional light sources generally have a low light energy utilization rate due to traditional light sources. I want to increase the light energy utilization rate through reflectors, but the reflectors have a large diameter, while the front of modern cars is low and uses Streamlined design, thus leaving less aperture for car headlights

Embodiment Construction

[0011] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0012] refer to Figure 1-3 , an LED light source headlamp according to the present invention, comprising a lamp body 1, a plurality of first LED lamps 2 are arranged on the edge of the lamp body 1, and the first LED lamps 2 are divided with the center of the lamp body 1 as the center of the circle. Ten arc-shaped LED strips are evenly distributed, the ratio of the radius of curvature of the arc-shaped LED strip to the radius of the inner circle formed by the arc-shaped LED strip is 2:1, and the clip between the arc-shaped LED strip and the inner circle formed The angle A is 20°, and a ring-shaped second LED lamp 3 is arranged on the outside of...

Abstract

The invention discloses an LED light source head lamp which comprises a lamp body. A plurality of first LED lamps are arranged at the edge of the lamp body and divided into ten evenly-distributed arc-shaped LED lamp strips with the center of the lamp body as the circle center, second annular LED lamps are arranged on the outer sides of the first LED lamps, third LED lamps are arranged on the inner sides of the arc-shaped LED lamp strips and are evenly and circularly distributed with the center of the lamp body as the circle center, fourth annular LED lamps are arranged on the outer sides of the third LED lamps, and a light transmitting cover is arranged on the outer sides of the third LED lamps and the fourth LED lamps. The LED light source head lamp further comprises a single-pole three-throw switch. According to the LED light source head lamp, the defects in the prior art can be overcome, the different LED lamps controlled by the single-pole three-throw switch are designed, the installation positions of the LED lamps are reasonably designed, different lighting levels are adjusted, and lighting dead zones are reduced.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED light source headlamp. Background technique [0002] At present, the light sources of automobile headlights mostly use halogen bulbs, such as H4 bulbs. Halogen bulbs have a large luminous volume, a short lifespan, and low utilization of light energy. Light-emitting diodes (Light-Emitting Diode, LED), as a new type of light source, have the characteristics of high luminous efficiency, long service life, and high reliability, and have been widely used in various lighting products at present. With the continuous maturity of LED technology and the reduction of cost, it has become possible to use LED as a car headlight, so LED is also called the fourth-generation car light source. Car headlights using traditional light sources generally have a low light energy utilization rate due to traditional light sources. I want to increase the light energy utilization rate through reflectors, but the reflector...
