Embodiment Construction

[0015] refer to figure 1 , figure 2 , a kind of active car headlight that can improve the visibility in rain and snow, comprises lampshade 3, is provided with the LED lamp array 1 that is made up of a plurality of LED units 2 in the lampshade, is provided with high frame rate ( 120Hz) camera 4. Each LED unit 2 in the LED lamp array is composed of a parabolic reflective surface 5 and an LED lamp placed at the focal point of the parabolic reflective surface. Each LED bulb emits a narrow beam, and due to the limitation of the parabolic reflector 5 of the highly reflective material, the emitted beam 6 is in a straight line.

[0016] see image 3 , the camera 4 bidirectional signals are connected to a CPU evaluation unit 7 (a general digital signal processor can be used, such as TI company T500 series), the output signal of the CPU evaluation unit is connected to an LED lamp control unit 8, and the output of the LED lamp control unit is connected to the LED lamp Each LED light...

Abstract

The invention discloses an active automobile headlamp capable of improving visibility in rain and snow, which comprises a lampshade. The active automobile headlamp capable of improving the visibility in rain and snow is characterized in that the inside of the lampshade is provided with an LED (light emitting diode) lamp array consisting of a plurality of LEDs; the lampshade above the LED lamp array is provided with a camera; the bidirectional signal of the camera is connected with a CPU (Central Processing Unit) evaluation unit; the output signal of the CPU evaluation unit is connected with an LED lamp control unit; and the output of the LED lamp control unit is connected with each LED lamp in the LED lamp array.

Description

technical field [0001] The invention relates to an automobile headlight. Background technique [0002] When driving at night on a rainy (snowy) day, on the one hand, high illumination is required to improve visibility; on the other hand, high illumination makes the raindrops (snowflakes) close to the car receive strong illumination and strong reflection, which seriously affects visibility. Existing automobile headlights cannot solve the above problems, thereby bringing potential safety hazards to driving at night in rainy and snowy days. Contents of the invention [0003] The invention aims at the problem that the headlights of ordinary automobiles affect the visibility when driving at night in rainy and snowy days, and provides an intelligent active car that not only maintains a certain light intensity, but also does not cause strong reflection of rainy and snowy days, and improves driving safety at night in rainy and snowy days. headlights. [0004] To achieve the abov...
