Lamp body fixture 10 is formed in one structure, including fixed plate 10-1 and parallel two that stagger with fixed plate 10-1 Journal stirrup 10-2, one of them journal stirrup 10-2 are with the left hand edge of fixed plate 10-1 by one piece of vertical curved support plate 10-6 even Connecing, another journal stirrup 10-2 is connected by the curved support plate 10-6 that another block is vertical with the right hand edge of fixed plate 10-1, fixing The center of plate 10-1 offers the via 10-3 that the rear portion for connecting rod 4-2 passes and coordinates with the middle part of connecting rod 4-2, via 10-3 is the round rectangle hole of the middle part mating shapes with connecting rod 4-2, and the edge of fixed plate 10-1 has outlet breach 10-5, two journal stirrup 10-2 offer the connecting hole 10-4 that be connected fixing with base of headlight 11.

When assembling, the rear portion of connecting rod 4-2 sequentially passes through the centre bore of base of headlight 11, the via of lamp body fixture 10 10-3, the middle part of connecting rod 4-2 is through the centre bore of base of headlight 11, and is positioned at via 10-3, the end face of limited step with Lamp body fixture 10 against, connecting rod 4-2 by the spacing of limited step and external screw thread and coordinating of locking nut 6 and and lamp Body fixture 10 is fixing to be connected, and lamp body fixture 10 is by two attachment screws 5 and coordinating of two connecting hole 10-4 and car Lamp base 11 is fixing to be connected, and the rear end of connecting rod 4-2 and thermal component 9 are fixed be connected by bolt 7 and the cooperation of nut 8.

As it is shown in figure 5, the luminous intensity distribution of distance light reflector 3 uses total-reflection type, the reflection of the reflecting mirror 3-1 of distance light reflector 3 Face is put together by 30 pieces of free form surfaces, and its basal plane is the paraboloid of revolution, according to light distribution, the mesh of high-beam light source master chip 1 The pattern on filament shield at the size of the curved surface lens of front LED headlamp and distance light source 25m determines that distance light is anti- The relevant parameter of emitter, the determination method of the relevant parameter of distance light reflector relates to luminous reflectance law, Light energy transfer principle, material The multi-subject knowledges such as and calculus, belong to prior art.

The type of car headlamp can be divided into reflection-type and the big class of porjection type two at present.Physical dimension is as follows:

Reflection-type headlamp: most reflection-type headlamp lens light-emitting window footpath >=70mm, lamp housing depth dimensions≤ 120mm；

Porjection type headlamp: most porjection type headlamp lens light-emitting window footpath >=60mm, lamp housing depth dimensions≤ 150mm；

In order to allow LED long-distance light light source module be popularized and to promote, improve universal performance, LED long-distance light The overall dimensions of light source module must meet the essential condition that two above is harsh simultaneously: i.e. LED long-distance light light source module goes out Outer caliber size≤the 60mm of light direction, the distance size≤120mm of the rear end of lampshade 13 to connecting rod 4-2.

As shown in Figure 6, basal plane (i.e. the paraboloid of revolution) equation of the reflecting mirror 3-1 of distance light reflector 3 is X²+Y²=4FZ,

For improving the utilization ratio of light, high-beam light source master chip 1 is positioned at the focus 20mm model of distance light reflector 3

In enclosing；Wherein, D, H and θ are respectively the bore of the paraboloid of revolution, the degree of depth and cornerite

X²+Y²=4FZ (1)

$TAN\mathrm{\θ}=\frac{D}{2(H-F)}---\left(2\right)$

$X^2+Y^2={\left(\frac{D}{2}\right)}^2---\left(3\right)$

General white light LEDs lambert's body light source intensity distribution is with reference to Fig. 7, and selecting light distribution is lambertian distribution light source, luminous Face normal direction largest light intensity is i₀, light with normal isTime light intensity be i_ε=i₀Cos ε, then its total light flux is:

${\mathrm{\Φ}}_0={\∫}_0^{\frac{\mathrm{\π}}{2}}{\∫}_0^{2\mathrm{\π}}{i}_0\sin \mathrm{\β}COS\mathrm{\β}d\mathrm{\α}d\mathrm{\β}={\mathrm{\πi}}_0$

Assume that distance light reflector 3 is ideal reflector, then its efficiency of light energy utilization η is represented by:

$\begin{array}{c}\mathrm{\η}=\frac{(\mathrm{\θ}-\sin \mathrm{\θ}\cos \mathrm{\θ})}{\mathrm{\π}}\\ =\frac{1}{2\mathrm{\π}}-\{2\arctan \left(\frac{4\mathrm{DF}}{4F^2-D^2}\right)-\sin 2\arctan \left(\frac{4\mathrm{DF}}{4F^2-D^2}\right)\}\end{array}$

In theory, cornerite is the biggest, and optical energy utilization efficiency is the highest, and the reflecting mirror processing and manufacturing of distance light reflector simultaneously can more come The most difficult.It practice, when wrap angle ＞ 110 °, the efficiency of light energy utilization would not clearly improve along with the increase of cornerite；Cause This, be defined as 110 ° by cornerite, both can be effectively improved optical energy utilization efficiency, and the reflecting mirror of distance light reflector can be made again to process Manufacture will not be excessively difficult.

In conjunction with above equation, D=2.8F can be obtained.

Due to LED long-distance light light source module light direction outer caliber size≤60mm, depth dimensions≤120mm, take The light direction of LED long-distance light light source module outer caliber size=50mm, then focal length F=50/2.8=17.85mm, take F =18mm.

The light energy that high-beam light source master chip 1 sends all passes lampshade after the reflecting mirror of distance light reflector 3 reflects 13 injections, can meet the distance light light distribution requirements of GB 25991-2010 vapour Vehicular LED headlamp.
