Intelligent headlamp based on projection principle

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...

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 oncoming vehicle will be discounted. In this case, the interference of the human eye with the high beam light on will accelerate the decline of this judgment. When you turn on the high beam light, the The car has always misjudged your speed and distance, and the car should have slowed down, but he safely avoided the bicycle or started to overtake another car. At this time, the high beam may be counterproductive; 3. The super large halo produced by the high beam It will occupy a large part of the area of ​​human vision, so that the driver's judgment on the width of the oncoming car and the situation behind it will be reduced, so that wrong operations will be taken; There will be a large area of ​​halo in the rearview mirror. If the car that catches up with you has a light interior, the interior of the car will undoubtedly be as bright as if the lights are on.
