Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in figure 1, the present embodiment provides a kind of illuminating light beam transmitter of motor vehicles, drawn by light source 1, light
Part 2, light-beam forming unit 4 and governor motion 3 is led to form.
Transmitting device of the light guide member 2 as light source, it is the leaded light device of flexible, there is input, output two
Port, input is placed at light source, after light is incident to its input, the principle of total reflection can be utilized, in light guide portion
Roundtrip onwards transmission inside part, until being exported after transmitting to its output end from output end.
Governor motion 3 is for fixing the mechanism of the output end of light guide member 2, is provided simultaneously with certain regulatory function, can
With overall or individually regulation light guide member 2 position.
Light-beam forming unit 4 is one group of thick lens, and light, can be by reflecting institute by the lens surface of particular design
The light of input is redistributed according to required, forms required output light shape.
As shown in figure 1, it is placed in the present embodiment by the use of LED as light source 1 at the port of light guide member 2, by light
The light that source 1 is launched is incided in light guide member 2, and light guide member 2 used can be fibre bundle or equally can be with
Realize the optics that light is totally reflected wherein.In the present embodiment, using fibre bundle as light guide member 2, institute
The fibre bundle of meaning, i.e., it is bundled into a branch of compliant member that can be used for leaded light by processing by a number of optical fiber；Due to working as
It after light coupled into optical fibres beam, can be totally reflected in each inside of optical fibre, be exported after arriving at the end of fibre bundle.
Light guide member exit end 5 is connected with governor motion 3, the light of light guide member 2 is guided to light guide member exit end 5
Incident radiant as light-beam forming unit 4.When light from the light guide member exit end 5 of light guide member 2 be incident to by
After the light-beam forming unit 4 of particular design, required light shape can be formed on road surface.
It is connected by governor motion with fixed mechanism, the light guide member of light guide member 2 can be adjusted according to demand
The relative position of exit end 5 and light-beam forming unit 4.By the relative distance of light guide member exit end 5 and light-beam forming unit 4
Elongate, as shown in figure 3, can produce, the angle of divergence is smaller, more poly- light beam, can illuminate more remote position.Such as light is drawn
The relative distance for leading part exit end 5 and light-beam forming unit 4 shortens, as shown in Fig. 2 the wider light of the angle of divergence can be produced
Beam, illuminate the more broad region of front part of vehicle.Vehicle, can be according to the situation, speed, road of surrounding environment in actual travel
Face lighting condition voluntarily adjusts required output lighting demand.
As shown in Figure 4,5, adjust the exit direction of the light guide member exit end 5 of perpendicular glazing guide member 2 with
The angle of the axis direction of light-beam forming unit 4, then when light guide member exit end 5 irradiates towards ground direction, beam shaping
The outgoing beam of device 4 also can correspondingly ground irradiate, if on the contrary, light guide member exit end 5 towards front upper place irradiate when, light
The outgoing beam of beam apparatus for shaping 4 equally can be towards irradiation above Chinese herbaceous peony.Vehicle in actual travel, can according to go up a slope or
During descent run, required lighting demand is adjusted.
Similarly, the exit direction such as light directing arrangement light guide member exit end 5 on adjustment horizontal plane fills with beam shaping
Put the angle of 4 axis directions, then when light guide member exit end 5 irradiates towards left side, the outgoing beam of light-beam forming unit 4
Can accordingly towards right side irradiate, if on the contrary, light guide member exit end 5 towards right side irradiate when, the emergent light of light-beam forming unit 4
Beam can equally irradiate towards left side.Vehicle can voluntarily be adjusted in actual travel according to when turning left or turning right traveling
Required lighting demand.
In the present embodiment, because the light of light source outgoing is first coupled into by light guide member 2, afterwards again by light guide portion
The exit end of part 2, as the incident light source of light-beam forming unit 4, exit end is light guide member exit end 5 herein.Therefore
There is the high free degree of comparison when laying LED light sources 1.Substantial amounts of LED points can be opened and laid into lighting module, so as to
The accumulation for avoiding LED from generating heat, improve the overall luminous flux output of lighting module.
