Problems solved by technology

[0002] The car headlight system is mainly composed of low beam and high beam. The high beam illuminates the road ahead and road sign information as far as possible within a certain brightness range. Although the high beam can improve sight, Expand the observation field of view, but there are still many hidden dangers in the high beam: 1. When meeting cars at night, the high beam can visually blind the opposing driver instantly, and the blinding time depends on the driver's own vision and the surrounding environment. The time will also be different, but it will last for about 2 seconds at the fastest. During these two seconds, the driver is driving with his eyes closed, and his ability to observe the surrounding pedestrians and the vehicles coming in front and behind is greatly reduced; 2. Night vision Not good, so the human eye's judgment of the speed of the

Embodiment 1

[0022] Example one, refer to Figure 1-Figure 5 , The left and right headlamps have the same structure, the left headlamp / right headlamp is composed of the first lighting unit A, and the LED lamps 10 constituting the first lighting unit A are evenly spaced. The light-emitting surface of the LED lamp 10 and the focal distance of the lens 30 It is proportional to the distance between adjacent LED lights 10. Since the LED lights 10 here are arranged evenly spaced, if the light emitting surface of the LED lights 10 is set at the focal point of the lens 30, then the light distribution screen will appear one by one lighting areas arranged at intervals; the light emitting surface of the LED lights 10 A certain distance is provided between the focal point of the lens 30 and the gap formed by the LED lamp 10 on the light distribution screen can be compensated, so that the entire high-beam type is uniformly distributed. Such as Figure 4 As shown, in this embodiment, preferably, the firs...

Embodiment 2

[0024] Example two, see Figure 6-Figure 10 , The left and right headlamps have the same structure. The left headlamp / right headlamp is composed of the second and third lighting units B and C. The second and third lighting units B and C both include the LED lamps 10 arranged at intervals and all The LED lamp 10 is located in the same light-emitting surface, the light-emitting surface of the LED lamp 10 is located at the focal point of the lens 30, and the projection of the LED lamp 10 of the third lighting unit C on the light distribution screen is located in the second lighting unit B. Between projections on the light screen. The basic principle of this structure is that the interval between the second lighting unit B on the light distribution screen is compensated by the third lighting unit C, so that the entire light pattern is continuous.

[0025] As a preferred solution of the present invention: the second lighting unit B is composed of five LED lamps 10, the middle one LED...

Abstract

The invention relates to the technical field of automobile lamp illumination, in particular to an intelligent headlamp based on the projection principle. A light source constituting the headlamp is formed by arranging multiple LED lamps horizontally, light rays emitted by all the LED lamps are emitted by a reflector and a lens and then reach a light distribution screen and form continuous illumination areas, the LED lamps are turned on and turned off independently, and after any LED lamp is turned off, a dark region appears in the illumination area corresponding to the LED lamp to be used for being kept away from other vehicles or pedestrians. The headlamp is formed by multiple LED lamps, the LED lamps can be turned on and turned off according to different road conditions, influences on other vehicles or pedestrians can be avoided, the view of the driver of a current vehicle cannot be influenced, and traffic safety is further improved.

Description

Technical field [0001] The present invention relates to the technical field of automobile lamp lighting, in particular to an intelligent headlamp based on the principle of projection. Background technique [0002] The car headlight system is mainly composed of low beam and high beam. The high beam illuminates the road and street sign information as far as possible within a certain brightness range. Although the high beam can improve the line of sight, Expand the field of view, but there are still many hidden dangers in the high beams: 1. When meeting cars at night, the high beams can make the opposing driver visually blind. The blinding time depends on the driver’s own vision and the surrounding environment. The time will be different, but it will last for about 2 seconds at the earliest. In these two seconds, the driver is driving with closed eyes, and the ability to observe the surrounding pedestrians and the incoming vehicles before and after is greatly reduced; 2. Night sight...
