Second embodiment
Figure 10 to Figure 15 is please referred to, the utility model second embodiment provides a kind of light projection device P comprising: one Load bearing unit 1, a first light source 2, a second light source 3, a lightproof unit 4 and a lens 5.First light source 2 and second light source 3 are all It is set on load bearing unit 1, wherein first light source 2 includes that at least one first luminescence unit 21 and one is right with the first luminescence unit 21 The first reflector element 22 that should be arranged, second light source 3 include at least one second luminescence unit 31 and one and the second luminescence unit 31 The second reflector element 32 being correspondingly arranged.Lightproof unit 4 is set to the front of load bearing unit 1, and lens 5 are set to lightproof unit 4 Front.It is worth noting that, the first luminescence unit 21 has one first light-emitting surface 211, the second luminescence unit 31 has one the The light direction of two light-emitting surfaces 311, the light direction of the first light-emitting surface 211 and the second light-emitting surface 311 is on the contrary, and the first light-emitting surface 211 and second light-emitting surface 311 it is coplanar or rough near same plane, more precisely, the first light-emitting surface 211 goes out with second Spacing between smooth surface 311 is 0 to 5 millimeter, preferably between 0 to 3.2 millimeter.In this way, the light of the present embodiment is thrown Injection device P can improve light utilization efficiency under the premise of meeting small form factor requirements.
The main difference of the present embodiment and first embodiment is: lightproof unit 4 is a transparent occulter, and along partition 11 thickness direction extends.About load bearing unit 1, first light source 2, second light source 3 and lens 5 technical detail, can refer to Described in one embodiment, therefore no longer it is described in detail in this.It should be noted that the notch shape of the shape of lightproof unit 4 and partition 11 Shape matches, and the width of lightproof unit 4 is about roughly equal to the gap width of partition 11, and the extended distance of lightproof unit 4 does not have Special limitation.Wherein there is lightproof unit 4 one and the second loading end 11b of partition 11 to be located at ipsilateral bottom surface 42, use Meet horizontal "cut-off"line required by dipped headlight to be formed, that is to say, that the dipped headlight as caused by light projection device P Light type has clearly "cut-off"line.Bottom surface 42 includes one first plane 421, an inclined-plane 422 and one second plane 423, the first plane 421 is higher than the second plane 423, and inclined-plane 422 is connected between the first plane 421 and the second plane 423.It needs It is noted that according to different needs, the bottom surface 42 of lightproof unit 4 can be a flat surface, that is to say, that projected by light Dipped headlight light type caused by device P is symmetrical light type.
In the present embodiment, the material of lightproof unit 4 can be glass, silicon-oxygen polymer (silicone) or polycarbonate (PC), but it is not only restricted to this.As shown in figure 12, there is a preset distance D3, and preset distance between lightproof unit 4 and partition 11 D3 between 0.01 millimeter to 1 millimeter, in this way, can to avoid first light source 2 light between lightproof unit 4 and partition 11 Direct out injection.It should be noted that once the light of first light source 2 directs out between lightproof unit 4 and partition 11 It projects, it will cause have veiling glare generation above the "cut-off"line of dipped headlight light type.
Figure 14 and Figure 15 is please referred to, it, can be with when the light L1a of the first luminescence unit 21 is projected to the first reflector element 22 It generates primary event light L11a and is projected to bottom surface 42, and primary event light L11a can pass through the anti-of bottom surface 42 again It penetrates, is projected to lens 5 to generate secondary reflection light L12a from the top of lens axis 51, and project outward by lens 5, from And form a part of dipped headlight light type.In addition, the light L1b when the first luminescence unit 21 is projected to the first reflector element 22 When, it can produce primary event light L11b directly through the gap of lightproof unit 4 and lens 5, and under lens axis 51 Side is projected to lens 5, and is projected outward by lens 5, to form another part of dipped headlight light type.Complete dipped beam Type is to be made of this two parts.Significantly, since the distance between lightproof unit 4 and partition 11 are limited (very Closely), primary event light L11 and injection can not be directed out between lightproof unit 4 and partition 11.
When the light L2a of the second luminescence unit 31 is projected to the second reflector element 32, primary reflecting light also can produce Line L21a is projected to bottom surface 42, and primary event light L21a only has a portion can be again by the anti-of bottom surface 42 Penetrate, be projected to lens 5 to generate secondary reflection light L22a from the lower section of lens axis 51, and by the lower half of lens 5 to Outer projection, to form a part of high beam light type, the another part of primary event light L21a can then enter shading Unit 4 (i.e. transparent occulter) and generate Fresnel reflection losses (Fresnel loss).In addition, when the light of the second luminescence unit 31 When L2b is projected to the first reflector element 22, primary event light L21b can produce directly through lightproof unit 4 and lens 5 Gap, and lens 5 are projected to from the top of lens axis 51, and project outward by lens 5, to form high beam light type Another part.Complete high beam light type is to be made of this two parts.It is worth noting that, in the bottom of lightproof unit 4 Surface 42 does not plate under the framework of any highly reflective material, if the second of bottom surface 42 and the second luminescence unit 31 goes out light Face 311 it is coplanar or it is rough in the same plane, then when the primary event light L21a of second light source 3 is projected to bottom surface 42 Generated Fresnel reflection losses can achieve minimum.
Preferably, as shown in Figure 16 to Figure 20, a reflection layer can be formed in the bottom surface 42 of lightproof unit 4 43, reflection layer 43 can be formed by highly reflective material (such as aluminium, silver).In this way, the light L2a when the second luminescence unit 31 is thrown When being incident upon the second reflector element 32, it can produce primary event light L21a and be projected to reflection layer 43, and primary event light L21a all can generate the lower half that secondary reflection light L22a is projected to lens 5 by the reflection of reflection layer 43.Separately Outside, when the light L1a of the first luminescence unit 21 is projected to the first reflector element 22, it can produce primary event light L11a throwing It is incident upon reflection layer 43, and primary event light L11a all can generate secondary reflection light by the reflection of reflection layer 43 Line L12a is projected to the upper half of lens 5.It should be noted that under the framework that lightproof unit 4 does not have reflection layer 43, it is right The generation in the light of second light source 3 has total reflection the phenomenon that.And under the framework that lightproof unit 4 has reflection layer 43, it is right In second light source 3 light according to reflection layer 43 reflectivity difference, have different degrees of detraction.
It is worth noting that when barn door of the lightproof unit 4 using opaque material, high beam light type and dipped beam There can be apparent dark space between type.When lightproof unit 4 is using transparent occulter, between high beam light type and dipped headlight light type Dark space it is less obvious.When lightproof unit 4 has reflection layer 43 using transparent occulter and its bottom surface 42, can incite somebody to action It eliminates dark space between high beam light type and dipped headlight light type.
