Description
One, technical field
The invention belongs to a kind of automobile front means of illumination and control setup.
Two, background technology
At present, the standard of full-sized car head light all adopts four lamp systems, its lighting form is, when implementing far lighting, four country beams are all worked, when implementing lower beam illumination, two dip filament work in the outside of big lamp assembly about having only, the lighting system of this light is science neither, wastes energy again and bulb, its major defect is, when (1) headlight was in far lighting, the country beam of four headlights was to throw light at a distance in the place ahead, and all passing lights are not all worked, exist in-plant road surface like this and do not see Chu and form the vision blind area, directly affect night traffic safety and reliability.When (2) headlight is in lower beam illumination, have only two the dipped beam work in the outside, when if wherein a dip filament damages, then cause a side passing light job, opposite side does not work, it is obviously not enough to occur road surface brightness like this, and cause vehicle show that width is unclear, when crossing, bring potential safety hazard for automobile.(3) the relatively long lower beam illumination of automobile far lighting period of service when night running is a vehicle when crossing, and just can use, and period of service is relatively short.So the damage rate of headlight high beam filament is more much higher than the damage rate of dip filament.Automotive bulb generally all adopts two filamentray structures, if when in a single day headlight high beam filament damages, this bulb is had to discard, at this moment be a kind of waste to bulb, moreover, the passing light of two interior Side lights in design at all by idle not usefulness, more outstanding to the waste of bulb like this.
Three, summary of the invention
Of the present invention month be to overcome the above-mentioned shortcoming that existing automotive lighting exists and compound luminous intensity distribution means of illumination of a kind of automobile front and control setup are provided.
For achieving the above object, the solution that the present invention takes is that the compound luminous intensity distribution means of illumination of a kind of automobile front is characterized in that:
(1) headlamp beam switch is in distance light mode of operation elbow, and the light of four headlights can be carried out distance light, the compound luminous intensity distribution illumination of dipped beam, i.e. each distance light of left and right sides headlight, dipped beam work automatically;
When (2) headlamp beam switch is in low-beam operational state, under the normal working, each the dip filament work in two left lamps and two the right lamps, when the dipped beam of a certain headlight damaged, this headlight can be transformed into the dipped beam work of homonymy another headlight automatically;
When (3) headlamp beam switch is in the distance light mode of operation, when the headlight high beam filament of one headlight or dip filament damage, can exchange automatically between the head light and reconfigure the compound luminous intensity distribution illumination of distance light, dipped beam, up to the filament of head light till all exchange work finishes.
The advantage of the compound luminous intensity distribution means of illumination of this kind automobile front is:
When (1) headlamp beam switch is in the distance light mode of operation, the light of four headlights can be carried out distance light, the compound luminous intensity distribution illumination of dipped beam automatically, be each distance light of left and right sides headlight, dipped beam work, the remote illumination of existing like this distance light has dipped beam closely to throw light on again, make the lighting distribution of light of automobile more rationally even, make the visbility of road bright more clear, thereby thoroughly solved the drawback of existing car bulb illumination, improved the safety and the reliability of night travel widely, made the driver free and relaxed.
When (2) headlamp beam switch is in low-beam operational state, when the dipped beam of a certain headlight damages, this headlight can be transformed into the dipped beam work of another headlight automatically, thereby the road surface luminance shortage occurs when thoroughly having solved the work of single dipped beam and vehicle shows the phenomenon that width is unclear, greatly reduce the accident rate of traffic.
When (3) headlamp beam switch is in the distance light mode of operation, when the headlight high beam filament of a certain headlight or dip filament damage, can exchange automatically between the head light and reconfigure distance light, the compound luminous intensity distribution illumination of dipped beam, up to the filament of head light till all exchange work finishes, improved the Occupation coefficient of bulb so greatly, the wastage rate of bulb can be reduced to about 40%.
