Abstract
The utility model relates to a changeable filter light-distribution lamp sheet for a large headlight, which is that the front piece of corrugation-shaped glass and the rear piece of the corrugation-shaped glass are arrayed to form into an air layer space; an upper vent, a lower vent, a left vent and a right vent are communicated with the air layer space; one end of a liquid and gas pipe is sheathed with a liquid and gas opening; the other end is sheathed with a ram pot and a cylinder barrel to form a changeable light filtering screen; therefore, luster angles and photochromic angles are controlled to eliminate glare light to achieve that illumination is soft and occupying area of light is large. The utility model has the advantages that the far and near light of an original large headlight are remained, various illumination selections for night driving with alternate use are added, and the number of accidents caused by glare light is reduced; The utility model is suitable for the selection for front illumination with different shapes; the number of accidents caused by glare light is reduced; the utility model is suitable for the installation of large headlight for front illumination with different shapes.
Description
The utility model relates to a kind of headlight luminous intensity distribution lamp sheet, and especially ram pot is advanced back in the gas-bearing formation space that is formed by luminous intensity distribution line shape glass anter, glass rear panel, advances the back-steam pressure cylinder, and the control that liquid, tracheae combine filters and becomes phototropic, luminous intensity distribution lamp sheet.
Operation at motor vehicle night, headlight produces dazzling incandescence of dazzling the eyes, and causes human pilot, pedestrian's vision is panic and produce and select the circuit confusion, very easily brings out traffic accident, and uses dipped headlights to exist defectives such as illumination is low, the light paving is little.
The purpose of this utility model provides a kind of headlight distance light can the optical filtering and is a kind of gloss, photochromic soft dazzling-light free, the big illumination in light paving, and can be used alternatingly the luminous intensity distribution lamp sheet of incandescence, sheen, coloured light according to the road conditions needs, reaching driving, meeting, pedestrian zone has the selection of multiple illumination mode, reduces because of before shining light-initiated traffic accident.
In order to achieve the above object, the solution that the utility model adopts is various gardens shapes, square and rectangle luminous intensity distribution lamp sheet, it includes the glass anter of line shape, the glass rear panel, front and rear row places lamp sheet peripheral edge along the fused whole lamp sheet that forms a gas-bearing formation space, under lamp sheet edge, a left side, liquid return hole is advanced on the right side, there is into return-air mouth top, lamp sheet edge, advance liquid return hole and liquid Guan Yiduan fit, advance return-air mouth and tracheae one end fit, the liquid pipe is end and the ram pot fit of containing liquid in addition, and steam pipe is end and pressure tank fit in addition, storage optical filtering liquid (liquid crystal in the ram pot, fluorescence liquid, coloured light liquid).The output of the hydraulic fluid of ram pot, vapour pressure tube air-breathing, the output of calming the anger of returning liquid, pressure tank of ram pot is by interlock electricity, air cock control.
Filament light-emitting forms the kicker light bundle by the reflection of reflection shield optically focused, is that infringement is subjected to according to personnel's eyesight and dazzling basic factor of dazzling the eyes, and the interlock electric switch is connected the hydraulic fluid tube and produced pressure fluid output, and pressure tank produces negative-pressure gas and sucks.Storage liquid output in the ram pot, through with the liquid pipe of fit to below, lamp sheet edge, left, right-hand advance liquid return hole and inject by line shape glass anter and put vapour sheaf space (for the acceleration feed liquor) the pressure tank generation negative-pressure sucking that forms with glass rear panel row, tracheae through fit, top, lamp sheet edge is advanced the return-air mouth and is discharged gas-bearing formation space gas, and feed liquor forms the big or small curtain that filters in gas-bearing formation space rapidly.(different liquid form the different curtains that filter).Filament light-emitting reflects to form strong beam by diffuser optically focused, and through the transmission filter of lamp sheet optical filtering curtain, the ray that harms one's eyes weakens, and the strong beam refraction forms dispersed light beam, the disappearance of credit light, and the light paving enlarges, and direct beam illumination is soft.The interlock electric switch is connected the ram pot negative pressure and is returned liquid, the output of calming the anger of pressure tank malleation, ram pot produces suction and returns liquid, through fit liquid pipe, advance liquid return hole with gas-bearing formation space liquid phegma pressure cylinder, pressure tank produces the output of malleation gas, through the fit tracheae, advance the return-air mouth gas is input into the gas-bearing formation space, luminous intensity distribution lamp sheet is returned to former incandescence transmissive operation state.
The utility model reaches change angle solution driving at night meeting, pedestrian zone photochromic, that suppress gloss with the optical filtering mode and dazzles the eyes the problem of bringing out traffic accident because of before shining light, provide distance light soft, a kind of illumination mode that the light paving is big, do not influence the use advantage that former headlight far light and near light changes again, several illumination (incandescent distance light, dipped beam, sheen) can be used alternatingly, need not change other modular construction of headlight on making, be applicable to the assembling of various types of vehicles difformity car light.
Be described further below in conjunction with drawings and Examples edition with parallel text utility model.
Accompanying drawing is the side-looking section schematic perspective view of an embodiment of the present utility model.
Shown in the accompanying drawing, a kind of line shape glass anter of headlight luminous intensity distribution lamp sheet and glass rear panel 2 rows place the 3 fused gas-bearing formation spaces 4 that form, lamp sheet edge, sheet respectively has into liquid return hole 5 along 3 lefts, right-hand, below, sheet advances return-air mouth 6 along 3 tops, all communicate with gas-bearing formation space 4, liquid pipe 7 one ends with advance liquid return hole 5 fits, liquid pipe 7 is end and ram pot 9 fits in addition, tracheae 8 one ends with advance return-air mouth 6 fits, steam pipe 8 is end and vapour pressure tube 10 fits in addition, ram pot 9 vapour pressure tubes 10 can be store various optical filterings by 11 controls of interlock electric switch in the ram pot 9, become light liquid 12.
Claims (2)
1, the variable filter luminous intensity distribution of a kind of headlight lamp sheet, it includes line shape glass anter 1, glass rear panel 2, gas-bearing formation space 4, advance liquid return hole 5, advance return-air mouth 6, liquid pipe 7, steam pipe 8, ram pot 9, vapour pressure tube 10, linked switch 11, it is characterized in that line shape glass anter 1 and glass rear panel 2 rows place the 3 fused gas-bearing formation spaces 4 that form, lamp sheet edge, sheet along 3 below, left, right-hand have an into liquid return hole 5, and return-air mouth 6 is advanced in 3 tops, sheet edge, all communicates with gas-bearing formation space 4, liquid pipe 7 with advance liquid return hole 5 fits, liquid pipe 7 is end and ram pot 9 fits in addition, tracheae 8 with advance return-air mouth 6 fits, tracheae 8 auspicious in addition with pressure tank 10 fits, hydraulic fluid is air-breathing, returns hydraulic pressure gas by linked switch 11 controls.
