Change module carrier 10b and have in side wall 200a one end relative with clamping part 100 into light opening 250.
By taking rectangular box-like photoelectric conversion module support 10b as an example, side wall 200b along framework be distributed and substantially perpendicular to
Extend where rectangle frame on the direction Z of plane, wherein side wall 200b can be in the rectangular opening that remote one end of clamping part 100 is surrounded by
Enter light opening 250.Light from photoelectric conversion module 10b dorsal parts (or downside) can by enter light opening 250 enter support sector 100 and
Enter the space between light opening 250, and arrive at accommodation space 150.
In the present embodiment, as shown in figs. 7 a and 7b, photoelectric conversion module support 10b further includes bottom 400, from
Side wall 200b extends to be formed in remote one end of clamping part 100 towards inframe direction.Now, bottom 400 is away from side wall 200b directions
Ora terminalis is surrounded by into light opening 250.In a height of 1639mm*983mm*40mm of the wide * of long * rectangle photoelectric conversion module, bottom
400 ora terminalis away from side wall 200b directions is, for example, 32mm with the distance on the outside of side wall 200b.
Photoelectric conversion module support 10b further includes reflecting surface 500, is arranged at side wall 200b medial surface 210, and position
The side in space in holding area 150 and between entering light opening 250；Reflecting surface 500 and can be supported by side wall 200b and bottom 400 and
Positioned at holding area 150 and enter between light opening 250.The material of reflecting surface 500 can be different with support 10b bodies, its light reflectivity
Also can be different with support 10b bodies, and preferably it is more than side wall 200b light reflectivity.
Specifically, reflecting surface 500 is the inner concave for concaving towards side wall 200b, and is reflected from the light for entering the entrance of light opening 250
Line is to holding area 150.Reflecting surface 500 has closest to the retracted position P of side wall 200b mono-, and includes upper cambered surface 550 and lower arc
Face 560, upper cambered surface 550 are connected to retracted position P with lower camber side 560.Upper cambered surface 550 is prolonged from retracted position P towards clamping part 100
Stretch, and may extend to the downside of clamping part 100；Lower camber side 560 extends from retracted position P away from clamping part 100.Lower camber side 560 can
Bottom 400 is further extended to, wherein lower camber side 560 preferably extends towards inframe direction to a greater degree compared to upper cambered surface 550.

Compared to known photoelectric conversion module support 90, photoelectric conversion module support of the invention as shown in Fig. 1 and 2B
10b improves the utilization rate of backlight.The backlight can be considered substantially towards the dorsal part (or downside) of photoelectric conversion module 1b (or 9)
Incident light source.Light from backlight calls back side light in the following text.As seen in figure 7 c, when back side light enters this hair from light opening 250 is entered
In bright photoelectric conversion module support 10b, reflecting surface 500 assists the back side light of projection thereon to be reflected towards holding area 150, is incorporated to
Penetrate smooth surface.For example, upper cambered surface 550 assists the back side light of projection thereon incident towards lower camber side 560, thereby lower camber side
560 again towards the reflection light of holding area 150.On the other hand, reflecting surface 500, which also assists in, catches the light away from smooth surface outgoing.Lift
For example, reflecting surface 500 can be captured from smooth surface outgoing and/or the light from smooth surface reflection, make it incident towards smooth surface again, carry
High-light-energy utilization ratio.
As shown in figure 8, the size of upper cambered surface 550 and lower camber side 560, upper cambered surface 550 and lower camber side 560 are on side wall 200b
The factor such as the height H5 and H6 of drop shadow spread and up or down cambered surface curvature all can further design and make foregoing dorsal part light projection
Back side light compensation and the efficiency of light energy utilization to smooth surface are more preferably changed, and light is uniformly distributed incident smooth surface.Such as lower arc
Face 560 is preferably more than upper cambered surface 550 in the height of drop shadow spread on side wall 200b in the height H6 of drop shadow spread on side wall 200b
H5.In addition, as shown in figure 8, upper cambered surface 550 in drop shadow spread on side wall 200b height H5 and lower camber side 560 in side wall 200b
The height H6 of upper drop shadow spread further has between 1.1：1.9 to 0.9：Proportion between 2.1；Wherein in the present invention one
In embodiment, height H5 and height H6 ratio are 1：2.For example, height H5 and height H6 is 100mm and 200mm respectively.Upper arc
The ratio of the radius of curvature R 5 in face 550 and the radius of curvature R 6 of lower camber side 560 is between 15：20 to 15：Between 25.For more preferably,
The radius of curvature R 5 of upper cambered surface 550 is less than the radius of curvature R 6 of lower camber side 560, wherein in an embodiment of the present invention, upper cambered surface
The ratio of 550 radius of curvature R 5 and the radius of curvature R 6 of lower camber side 560 is 15：23, and for example, 15mm and 23mm.
Furthermore as shown in figure 8, what lower camber side 560 was stretched out in drop shadow spread in vertical sidewall 200b planes from side wall 200b
Length is L1；Upper cambered surface 550 in drop shadow spread in vertical sidewall 200b planes from the side wall 200b length stretched out be L2.Preferable
In embodiment, L1 need to be more than L2, to provide preferable light distributing uniformity.
The photoelectric conversion module support of the present invention further receives optical analog analysis.To the software analyzed for example
For Tracepro softwares.Test result shows that the light of photoelectric conversion module support progress dorsal part of the present invention compensates, and compared to
Traditional photovoltaic modular converter support reaches 4.2% optical gain, that is, in identical enters light opening (i.e. the present invention enters light opening
250 enter light opening 95 with conventional stent) with the conditions of identical frame bottom area etc., the light of photoelectric conversion module of the present invention
Face is obtained 4.2% light quantity compared to Traditional photovoltaic modular converter more by backlight.Those light quantities and it is scattered in smooth surface.
Wherein, the Traditional photovoltaic modular converter support tested is black and silver color.When photoelectric conversion module support of the present invention is such as silver
During color, it has the effect of the light compensation of dorsal part.
The present invention is described by above-mentioned related embodiment, but above-described embodiment is only the example for implementing the present invention.
It must be noted that the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, it is contained in the spirit of claims
And the modification of scope and impartial setting are both contained in the scope of the present invention.
