Embodiment one

Referring to Figure 18, is the schematic perspective view of the embodiment one that in photo-translating system 100 shown in Fig. 1, optical-electrical converter group 31 and guide-lighting module 13 cooperatively interact.In the present embodiment, described guide-lighting module 13 is reflecting plate.Described guide-lighting module 13 and described optical-electrical converter group 31 respectively entirety are roughly platy structure, and arrange in an angle therebetween.Described reflecting plate receives the light beam from described light source, and reflects described light beam towards described optical-electrical converter group 31 surface delivery.

Wherein, described optical-electrical converter group 31 can receive the light beam directly provided from described light source, also can receive the light beam reflected through described guide-lighting module 13.Incorporated by reference to consulting Figure 19 a-19d, be the group of optical-electrical converter shown in Figure 18 31 and the side schematic view of guide-lighting module 13 under different illumination conditions.Therefore, according to the beam distribution on described optical-electrical converter group 31 surface, following several situation can be divided into.

Refer to Figure 19 a, described optical-electrical converter group 31 surface integral only receives the light beam directly provided from described light source.The light beam provided due to described light source covers optical-electrical converter group 31 surface comprehensively, and therefore, optical-electrical converter group 31 surface forms the illumination that all directions optical power density is evenly distributed.Under the illumination condition that described all directions optical power density is evenly distributed, the transform light energy of irradiating in its surface is electric energy by multiple photoelectric conversion unit band groups 37 of described optical-electrical converter group 31, and exports the electric energy of corresponding described photoelectric conversion unit band group 37 generation independently by described output 33.

Refer to Figure 19 b, described optical-electrical converter group 31 not only receives the light beam directly provided from described light source, also receive the light beam reflected through described guide-lighting module 13, and above-mentioned two kinds of light beams partly overlaps in described optical-electrical converter group 31.According to the overlapping cases of described optical-electrical converter group 31 receiving beam, described optical-electrical converter group 31 can be formed two and tie up parallel region, direction along described first:

Region one, only receive the light beam directly provided from described light source, the optical power density therefore in described region one is evenly distributed;

Region two, the light beam receiving the light beam directly provided from described light source simultaneously and reflect through described guide-lighting module 13, therefore described region two is overlapping regions of above-mentioned two kinds of light beams, and the optical power density in described region two is evenly distributed.

It can thus be appreciated that the optical power density in described region two must be greater than the optical power density in described region one.That is, along being parallel to described first dimension direction, the optical power density in described region one and the optical power density in described region two are uniformly distributed respectively; Along being parallel to described two-dimensional directional, the optical power density in described region two is greater than the optical power density stating region one.Namely being formed on described optical-electrical converter group 31 surface along described first dimension direction optical power detection, is the illumination of non-uniform Distribution along two-dimensional directional.

And described region one and described region two are parallel to described first dimension direction respectively, and therefore described region one and described region two comprise multiple photoelectric conversion unit band group 37 respectively.

And, photoelectric conversion unit band group 37 surface in described region one and described region two has optical power density respectively and to distribute identical illumination, then the transform light energy of irradiating in its surface is electric energy by described photoelectric conversion unit band group 37, and exports the electric energy of corresponding described photoelectric conversion unit band group 37 generation independently by described output 33.Photoelectric conversion unit band group 37 in described region one and described region two is all carry out opto-electronic conversion independently, and exports electric energy independently, does not disturb each other.

Refer to Figure 19 c, described optical-electrical converter group 31 not only receives the light beam directly provided from described light source, also receives the light beam reflected through described guide-lighting module 13, and above-mentioned two kinds of light beams are comprehensively overlapping and cover described optical-electrical converter group 31.So, in the illumination that described optical-electrical converter group 31 all directions formation optical power density is evenly distributed.Under the illumination condition that described all directions optical power density is evenly distributed, the transform light energy of irradiating in its surface is electric energy by multiple photoelectric conversion unit band groups 37 of described optical-electrical converter group 31, and exports the electric energy of corresponding described photoelectric conversion unit band group 37 generation independently by described output 33.

Refer to Figure 19 d, described guide-lighting module 13 is also likely not surperficial to described optical-electrical converter group 31 by any beam reflection, and described guide-lighting module 13 has blocked the light beam that the described light source of part sends on the contrary.Between the light beam sent due to described light source and described guide-lighting module 13, angle makes described guide-lighting module 13 not receive light beam from described light source, has blocked the described light beam of part on the contrary and has caused described optical-electrical converter group 31 to only have subregion to receive described light beam.Thus, the subregion receiving described light beam forms Fu Guang district in described optical-electrical converter group 31; All the other regions of described optical-electrical converter group 31 are not then covered by described light beam, form shading region thus in described optical-electrical converter group 31.

Described Fu Guang district adjacent with described shading region and along described first dimension direction be parallel to each other.So, along described first dimension direction, the Fu Guang district of described optical-electrical converter group 31 and shading region comprise multiple photoelectric conversion unit band group 37 respectively.

In described Fu Guang district, the optical power detection of described illumination.Therefore, photoelectric conversion unit band group 37 surface in described Fu Guang district has the illumination that optical power density is evenly distributed respectively, then the transform light energy of irradiating in its surface is electric energy by described photoelectric conversion unit band group 37, and exports the electric energy of corresponding described photoelectric conversion unit band group 37 generation independently by described output 33.

In described shading region, the light intensity of described sunlight direct light photograph is zero substantially.Therefore, photoelectric conversion unit band group 37 surface in described shading region does not have sunlight direct light photograph, then described photoelectric conversion unit band group 37 only produces a small amount of electric energy by scattered light, or can not produce electric energy.

It should be noted that, the photoelectric conversion unit band group 37 in described Fu Guang district and described shading region is all carry out opto-electronic conversion independently, and independently must export electric energy, does not disturb each other.Therefore, as long as the surface of described optical-electrical converter group 31 exists the illumination with enough optical power density, described optical-electrical converter group 31 just can produce electric energy.
