Abstract
The invention relates to an intelligent brightness regulation system for an automotive headlamp. The intelligent brightness regulation system is characterized by comprising a photoreceptor, a dimming circuit, a control circuit, a vehicular power supply and a headlamp, wherein the photoreceptor is mainly composed of photosensitive resistors; the dimming circuit is mainly composed of capacitors, controlled silicon and peripheral circuits thereof; when ambient light is weakened, the resistance of the photosensitive resistors is increased, and the component voltage applied on the capacitors is increased, so that the conduction angle of the controlled silicon is increased, the voltages at two ends of the headlamp are increased, and the brightness of the headlamp is increased; otherwise, if the ambient light is brightened, the resistance of the photosensitive resistors is decreased, the conduction angle of the controlled silicon is decreased, the voltages at two ends of the headlamp are decreased synchronously, and the brightness of the headlamp is decreased. According to the intelligent brightness regulation system for the automotive headlamp, the brightness of the headlamp is automatically regulated according to the ambient light through the coordination of the photoreceptor, the dimming circuit and the control circuit, so that the scientific sense of an automobile can be improved, the driving safety is improved, and the effect of energy saving is also achieved.

Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of headlight brightness intelligent regulating system.
Described a kind of headlight brightness intelligent regulating system, it is characterized in that being made up of photoreceptor, light adjusting circuit, control circuit, vehicle power and head light, photoreceptor is arranged on head light, and photoreceptor, light adjusting circuit, control circuit, vehicle power and head light connect into loop by wire; Photoreceptor is formed primarily of photoconductive cell, and light adjusting circuit, primarily of electric capacity, silicon control and peripheral circuit thereof composition, causes the resistance of photoconductive cell to increase when ambient light dies down, the dividing potential drop be added on electric capacity is made to increase, and then silicon controlled conduction angle is increased, increase front car light both end voltage, head light brightness increases, otherwise, if the light of environment brightens, then the resistance of photoconductive cell declines, and causes silicon controlled conduction angle to diminish, the both end voltage of front car light synchronously declines, and head light brightness is dimmed; The smooth dc voltage of vehicle power can be changed into low-voltage direct pulsating voltage and power to head light by control circuit.
The light-dimming method of described headlight brightness intelligent regulating system, it is characterized in that light-dimming method is as follows: open automobile front, this head light brightness intelligent regulating system starts, photoconductive cell is experienced ambient brightness in real time and changes resistance size, cause the resistance of photoconductive cell to increase when ambient light dies down, the dividing potential drop be added on light adjusting circuit electric capacity is made to increase, and then the thyristor operating angle of light adjusting circuit is increased, increase front car light both end voltage, head light brightness increases, otherwise, if the light of environment brightens, then the resistance of photoconductive cell declines, the silicon controlled conduction angle of light adjusting circuit is caused to diminish, the both end voltage of front car light synchronously declines, head light brightness is dimmed, closing automobile head light, then head light brightness intelligent regulating system is closed.The present invention, by the cooperation of photoreceptor, light adjusting circuit and control circuit, achieves head light environmentally light automatic regulating lightness, can promote the science and technology sense of automobile, namely improve travel safety, achieve again energy-conservation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
A kind of headlight brightness intelligent regulating system, be made up of photoreceptor, light adjusting circuit, control circuit, vehicle power and head light, photoreceptor is arranged on head light, and photoreceptor, light adjusting circuit, control circuit, vehicle power and head light connect into loop by wire; Photoreceptor is formed primarily of photoconductive cell, and light adjusting circuit, primarily of electric capacity, silicon control and peripheral circuit thereof composition, causes the resistance of photoconductive cell to increase when ambient light dies down, the dividing potential drop be added on electric capacity is made to increase, and then silicon controlled conduction angle is increased, increase front car light both end voltage, head light brightness increases, otherwise, if the light of environment brightens, then the resistance of photoconductive cell declines, and causes silicon controlled conduction angle to diminish, the both end voltage of front car light synchronously declines, and head light brightness is dimmed; The smooth dc voltage of vehicle power can be changed into low-voltage direct pulsating voltage and power to head light by control circuit.
The light-dimming method of this headlight brightness intelligent regulating system is as follows: open automobile front, this head light brightness intelligent regulating system starts, photoconductive cell is experienced ambient brightness in real time and changes resistance size, cause the resistance of photoconductive cell to increase when ambient light dies down, the dividing potential drop be added on light adjusting circuit electric capacity is made to increase, and then the thyristor operating angle of light adjusting circuit is increased, increase front car light both end voltage, head light brightness increases, otherwise, if the light of environment brightens, then the resistance of photoconductive cell declines, the silicon controlled conduction angle of light adjusting circuit is caused to diminish, the both end voltage of front car light synchronously declines, head light brightness is dimmed, closing automobile head light, then head light brightness intelligent regulating system is closed.
Vehicle power in said method has to pass through control circuit and vehicle power is changed into low-voltage direct pulsating voltage, can not directly use capacitor filtering to become smooth dc voltage, otherwise circuit cannot realize.Reason: low-voltage direct pulsating voltage can provide the pacing factor of zero-crossing switching to silicon control, the electric capacity cycle can be made again to charge, accurately complete silicon controlled synchronous plase-shifting trigger.
The present invention regulates head light brightness to have rapid, the highly sensitive feature of feedback, when environment is too dark, the brightness of automatic raising head light, improve traffic safety, when environment is too bright, decay head light brightness automatically, save electricity, this design science and technology sense is pure simultaneously, increases the bright spot of vehicle, lifting vehicle quality.
