Multi-auxiliary-function intelligent fog lamp and alarm method

Abstract

The invention discloses a multi-auxiliary-function intelligent fog lamp and an alarm method. The multi-auxiliary-function intelligent fog lamp comprises a circuit control module, a mixed light source module, a shaping optical module, a temperature control module, a relative vehicle speed measuring module and a mixed light source module angle adjustor. The mixed light source module comprises LED fog lamps and a laser fog lamp, wherein the LED fog lamps and the laser fog lamp are mutually coordinated and matched to emit light. The circuit control module is connected with the mixed light source module, and the shaping optical module is arranged at front of the laser fog lamp of the mixed light source module. The mixed light source module is connected with the temperature control module. The circuit control module is further connected with the relative vehicle speed measuring module, the output end of the relative vehicle speed measuring module is connected with the mixed light source module angle adjustor, and the output end of the mixed light source module angle adjustor is connected with the mixed light source module. A red light semiconductor laser device and LEDs are applied to an automobile fog lamp and mutually coordinated and matched to emit the light, so that the situation that safe driving on a road is guaranteed under the conditions of rainy days and foggy days at different lelvels, and the guarantee capability of road transportation is improved.

Description

technical field [0001] The invention relates to the technical field of warning lamps, in particular to a multi-auxiliary intelligent fog lamp capable of generating a bright red triangular light area behind a car in a foggy environment, and a warning method using the multi-auxiliary intelligent fog lamp. Background technique [0002] Fog lights are used in rainy, foggy or other low-visibility conditions for observation and warning of driving vehicles. Traditional fog lamps are designed and used with halogen lamps, etc., but due to the short service life of this type of bulbs, and high power consumption. With the continuous development of LED technology, traditional fog lamps are now being gradually replaced by LED fog lamps. LED is small in size, easy to use; long service life, durable, strong shock resistance, can exceed 20,000 hours, while the life of traditional halogen lamps is generally about 300 hours; high efficiency, less additional loss; fast response, different fro...

AI Technical Summary

Problems solved by technology

However, in the prior art, LED fog lamps have many disadvantages: first, the directionality of the LED light source is poor, and the irradiation area and shape are relatively fixed; second, the penetrating ability is poor. The distance is very limited; third, the function is single, and there are no auxiliary warning functions, etc.

However, the red triangle light area produced by the above-mentioned laser fog lights at the rear of the car is based on the foggy weather. When the fog concentration is high (foggy day), the laser is projected on the dense fog to produce a bright red triangle light area. , and when the fog concentration is not serious (little foggy day), the laser projection on the thin fog can only produce a weak red triangle light area, which makes it difficult for the driver behind to see the warning of the car, posing a major safety hazard
