Description
Technical field
The utility model relates to a kind of LED multiple light courcess car headlamp light adjusting mechanism.
Technical background
The adjusting mechanism of car headlamp is one of necessary structure function of head lamp; Existing head light setting mechanism is tending towards normalisation basically; But mostly existing adjusting mechanism is to adjust to independent light source; Be applicable to single light source, simple reflector system, its main purpose be for make car light dispatch from the factory debug can reach up and down catadioptre in extremely user's use about the adjustment.Along with the LED The Application of Technology is promoted, led light source is replacing the existing conventional light source of car headlamp.Because led module is the multiple light courcess system mostly, therefore adopt traditional adjusting mechanism, can't realize multiple light courcess adjustment function.Its reason owing to receive the light fixture space constraint, adopts independent catadioptre to realize optical function like the mirror diameter of single light source system 1; Generally can not surpass 120mm, so height is little before and after the adjustment amount, and the head lamp of led light source; Come common the realization by a plurality of light sources, and the light source that constitutes usually is very long and narrow, if use traditional adjustment mode; Amplitude is very big, all is unacceptable to moulding and outward appearance; 2, the multiple light courcess system is when the design passing light; Mostly be that the overlapping method of light type realizes optical design; That is to say that each light source all has its oneself luminous intensity distribution light type, combining forms the optical effect consistent with rules; And use traditional adjusting mechanism, can't realize the optical effect that many light type is synthetic.
The utility model content
The purpose of the utility model provides a kind of LED multiple light courcess car headlamp light adjusting mechanism, and this adjusting mechanism can be realized the unified light modulation to many light sources of LED, and the light modulation precision is high, and space throw amount is little.
The technical scheme of the utility model is: a kind of LED multiple light courcess car headlamp light adjusting mechanism is characterized in that: have two groups of identical trimming screw assemblies, vertical adjustment support, horizontal adjustment support, adjust support with lamp body bonded assembly fixed support and several unit; Every group of trimming screw assembly respectively by trimming screw, the nut that is threaded with trimming screw, be fixed on the bulb of nut one end, the adjustment ball cap that flexibly connects with bulb forms, adjust ball caps for two and be connected respectively through fastening trimming screw with the horizontal adjustment support with the vertical adjustment support; Be equipped with respectively in the framework of each unit adjustment support that light group unit, frame facet are equipped with the vertical adjustment box, be equipped with the framework bottom surface and lamp body bonded assembly fixed support and horizontal adjustment box; In each vertical adjustment box and each horizontal adjustment box, big gear wheel, miniature gears, the tooth bar that is connected with a joggle successively is housed respectively; Each tooth bar end be contained in the transmission ball cap and be connected each vertical adjustment support and the clamping of cooresponding with it the respectively transmission ball cap of each horizontal adjustment support with bulb that the transmission ball cap flexibly connects; Its axostylus axostyle of the Large Gear Shaft During that in the vertical adjustment box, is connected with big gear wheel is connected with the base key of each light group unit, and the axle head of this Large Gear Shaft During and unit adjustment rack shaft hole flexibly connect; Its axostylus axostyle of the Large Gear Shaft During that in the horizontal adjustment box, is connected with big gear wheel and fixed support axis hole flexibly connect, and the axle head of this Large Gear Shaft During and unit adjustment support are connected.
During use, fixed support and lamp body are connected, and trimming screw is contained on the lamp body, and the projection of nut 9 profiles is contained in the slideway of lamp body, rotate trimming screw nut is moved along slideway.
The advantage of present technique is:
1, the Adjustment System owing to each light group unit is connected on vertical adjustment support and each the horizontal adjustment support; Unify light modulation by the trimming screw assembly, each light source can independently be rotated, so no matter how long combination of light sources is; It all is the same rotating shared space; The angle of rotation also is the same, each dimming light source oscillating quantity very little with adorn to enclose between the gap also can design-calculated very little, satisfy the light fixture space requirement.
2, because vertical adjustment support, horizontal adjustment support are connected with the fore-and-aft adjustment parts through bulb, ball cap structure, it is very high to make multiple light courcess in adjustment, move smooth and easy, inspiration, precision.
3, this mechanism structure is simple, highly versatile.Big for adjustable positions property, even the multiple light courcess mechanism that can intersect, the single light source mechanism for adopting traditional trimming screw and accessory thereof still can adopt this mechanism, realizes the adjustment function, and this is that traditional dimming mechanism is irrealizable.
