It is in example shown in figure, entire shading surface 210 is partly formed to light transmission, wherein by this it is meant that, institute Stating shading surface 210 has a transmission less than 1, and the transmission adjusts from the optical conductor 100 or from the guide section The light quantity left in 120.
In addition, the shading surface 210 have shading section 211, the shading section be associated with the optical conductor 100 and Substantially cover or cover the optical conductor, wherein the shading section 211 equally partly light transmission.
As can be seen in Fig. 2, the light emission of the shading surface towards the mating plate 300 enters 310 direction of position and prolongs It stretches and there is a wall thickness process, the wall thickness examples of processes towards the direction that the light emission of the mating plate 300 enters position 310 It is shown in FIG. 5.
Generally, the light emission that the shading surface 210 covers the optical conductor 100 enters position 110 and towards the mating plate 300 light emission enters the direction extension at position 310, wherein the shading surface 210 need not fully extend up to the mating plate 300 Light emission enter position 310.
Because making every effort to the common uniform luminous impression of entire mating plate 300, the light emission enter position 110,310 and its that This arrangement is rendered as particularly critical region.In the case where not other light formation, that is to say, that passing through the screening In the case that photo structure component 200 does not weaken at least one region or position in the region or position targetedly, The luminous impression of the mating plate 300 has region or position bright or shine.
By means of it is described at least partially, the shading surface 210 of at least partly light transmission and its light towards the mating plate 300 The increased wall thickness process in direction (as shown in fig. 5) for injecting position 310, generates the wearing for optical conductor 100 and penetrates By the light of the mating plate and entered via the light emission by the mating plate 300 that position 310 is left and in the mating plate The light being distributed in 300, the smooth transition of brightness step that shows on the mating plate 300, so that the mating plate 300 Luminous impression equably shows.
The viewgraph of cross-section for the light-shielding structure component 200 being shown in FIG. 5 shows the difference of the shading surface 210 Wall thickness, the wall thickness is with d0、d1And d2To indicate, wherein the light emission towards the mating plate 300 from Fig. 5 enters position 310 The illustrative wall thickness process in direction can be with d0≤d1<d2To express.
For the improved homogenization of the luminous impression of the mating plate 300, the shading section 211 can equally have one Wall thickness process.
Entered in position 110 and the region of the guide section 120 in the light emission about expectation according to the optical conductor 100 Light leave direction and be configured with what kind of, the wall thickness of the shading section 211 can increase towards 140 direction of optical conductor end Or it reduces.
If the light for being originated from curved guide section 120 leaves the injection that direction is arranged essentially parallel to the optical conductor 100 The desired light of section 130 leaves direction extension (as shown in Figure 2), then recommendable can be, it is described The wall thickness process design of shading section 211 is gradually decreased at towards 140 direction of optical conductor end.
The light emission enter position 110, be substantially normal to the optical conductor 100 injection section 130 it is desired In the case that the light that light leaves direction extension leaves direction, then the direction towards optical conductor end 140 of the shading section 211 The wall thickness process gradually increased can be desirable.
In principle, the wall thickness of the shading surface 210 or wall thickness process are according to optical conductor 100 used in corresponding and described The light intensity of mating plate 300 and corresponding light source 101,301 is coordinated.
In order to targetedly project light from the guide section 120, described lead can be arranged in by projecting element 121 Into section 120, as shown by figs. 6 and 7.
Because generally the guide section of optical conductor is responsible for mixing the light of institute's feed-in, the injection element 121 Implement as follows in the guide section 120 of the optical conductor 100, so that although light is directed in the guide section 120 Property project, but the mixing of the light is not significantly affected so that for the injection section 130 mixing meaning The light that justice is lower and prepares substantially is not subjected to significant loss or changes.
For this purpose, the injection element 121 of the guide section 120 is constructed with columnar form of grooves, because of such shape Have less compared with the prism projected in section 130 for being for example arranged in the optical conductor 100 commonly used in the injection of light The radioactive nature being directed toward by force, as illustrated in Figure 7.
When the injection element 121 in the guide section 120 only in the short section along the guide section 120 When upper arrangement, the radius of spacing and its size or the columnar groove between each injection element 121 can be in the same manner Extension.
The spacing between each injection element 121 of the guiding area can select as follows in this case, So that the spacing corresponds to the spacing between each injection element 131 for projecting section 130, such as prism.
It is described columnar in the case where the light is projected via the longer section of the guide section 120 or region The size and/or radius of groove 121 and the depth of the groove 121 gradually can stretch ground in the guide section 120 Implement, wherein size such as size, the spacing between each groove, the radius of the columnar groove and/or depth are along institute It states optical conductor 100 and implements with gradually increasing or reduce towards 140 direction of optical conductor end.
In addition, described device can include comprising the optical conductor 100, the mating plate 300, the light source 101,301 and The shell 10 with shell covering part 20 of the light-shielding structure component, the shell covering part is for example as shown in figs. 1 and 2.
At the side of illustrative embodiment shown in figure for leaving the device 1 with optical conductor 100, also can There are two optical conductors 100 for enough settings, wherein the shading surface 210 can have other shading section 211 thus.
In addition, the optical conductor 100 can manipulate in which be independent of each other.
