Description

A kind of automotive LED headlamp module with distance-light function

Technical field

It the utility model is related to lighting apparatus technical field, and in particular to before a kind of LED automobile with distance-light function Illuminator module.

Background technology

The vehicle front lighting system of the projection of the existing distance-light one usually same light source of use (xenon lamp bulb, Or the integrated module type COB light source placed upward), with an ellipsoid reflector by the convergence of rays that light source is sent to light barrier On.Described light barrier, it is arranged to certain shape, ellipsoidal reflector is converged to and is in the light according to the requirement of traffic law Hot spot on piece is carried out cutting light, blocks unwanted part, and the hot spot cut after light is demarcated by projecting light and shade after projection objective Line clearly dipped beam hot spot.Described light barrier can be moved up and down to realize far and near light type by solenoid valve control Conversion.When light barrier is in top position, light barrier cuts out the hot spot above horizontal line, and dipped beam is projected by projection objective Light type；When light barrier moves down, the hot spot for converging to light barrier position is not blocked, and projection objective is projected positioned at water Hot spot above horizontal line, form the light type of distance light.

The vehicle front lighting system of the projection of existing distance-light one, the general structure using such as Fig. 1 and Fig. 2.Fig. 1 is A kind of projection HID lamp car headlamp (patent No. that U.S. Visteon Global Technologies, Inc company proposes For：The B1 of US 6,186,651), which employs an ellipsoidal reflector 10, and HID (high-voltage gas discharging light) bulb is sent Convergence of rays is located at the inner side focal position of ellipsoidal reflector 10, light meeting to the position of light barrier 22, the position of HID luminous points Another focus 2 after poly- is then located at the position of light barrier 22.Light after convergence cut at light by described light barrier 22 Reason, the hot spot that "cut-off"line clearly meets traffic law is then projected by the projection objective 24 in front.Described gear Mating plate 22, it is controlled up and down through magnetic valve 40, forms the switching of required distance light and dipped beam.

Visteon Global Technologies, Inc companies also proposed a kind of projection based on LED light source Car headlamp (Patent No.：The B2 of US 7,410,282), as shown in Figure 2.It is anti-by LED light source 12, the ellipsoid placed upwards Mirror 14, the mechanism that is in the light 20 and projection objective 26 is penetrated to form.It also uses an ellipsoidal reflector 14, and LED light source 12 is sent out The convergence of rays gone out is located at inner side Jiao of ellipsoidal reflector 14 to the position for the mechanism 20 that is in the light, the position of the luminous point of LED light source 12 Point position, another focus after convergence of rays is then positioned at the position for the mechanism 20 that is in the light.After the described mechanism 20 that is in the light will assemble Light carry out cut a light processing, "cut-off"line is then projected by the projection objective 26 in front and clearly meets traffic law Hot spot.The described mechanism 20 that is in the light, it is provided with magnetic valve and moved up and down, and forms cutting for required distance light and dipped beam Change.

The luminous intensity distribution principle of the low-beam function of the present embodiment is：Light barrier is located at the front focus position of projection objective, light barrier Single dipped beam LED light source is carried out to cut light, the light that a part of dipped beam LED light source is sent is blocked, is formed in horizontal line position bright Dark clearly demarcated dead line, after projection objective projects, the dipped beam hot spot for meeting traffic law is formed a long way off.

The luminous intensity distribution principle of the road function of the present embodiment is：3 free form surface convex lens vertical directions are to distance light LED light source Collimation luminous intensity distribution is carried out, horizontal direction then extends the luminous intensity distribution of certain angle to distance light LED light source, and the light distribution angle of horizontal direction is θ, θ is 20-30 degree；Preferably, θ is 24 degree；After free form surface convex lens luminous intensity distribution, distance light forms the oblateness of a narrow angle Focused light spot.

Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this The spirit and scope of utility model technical scheme.
