Description

Light collecting module

The invention relates to a concentrating module, in particular to a concentrating module capable of improving a concentrating ratio. Background technique

In recent years, with the rise of human environmental awareness, the research and development of renewable energy has received attention. Among them, because the sun light is easier to obtain than other renewable energy sources, the operators have invested a lot of money in the development of solar power.

At present, the method of solar power generation can be divided into two types. The first method of solar power generation is to convert the heat energy of sunlight into electric energy by means of photothermal conversion, and the second method of solar power generation is to use the photoelectric conversion method to convert the sun. The emitted light energy is converted into electrical energy.

In a solar cell system composed of a plurality of solar cell modules, it is most common to receive sunlight at a fixed angle. However, since the angle at which solar light is incident on the solar cell system varies with time and latitude and longitude of the set point, the amount of sunlight absorbed by the solar cell system is lowered, and the amount of power generation is lowered. Therefore, how to improve the photoelectric conversion efficiency of a solar cell system that receives sunlight at a fixed angle has become one of the research and development directions of related companies.

In addition, in order to increase the amount of sunlight absorbed by the solar cell system, a related company has proposed a solar cell system using a tracking module in combination with a solar cell module. The tracking module mainly includes a photo sensor and an electromechanical servo mechanism. The sensor is used to sense the change of the position of the sun, and the electromechanical servo mechanism is used to adjust the solar cell system to face the sun, thereby increasing the radiation amount of the solar module receiving sunlight. It should be noted that the erection angle of the sensor needs to be exactly parallel to the vertical angle of the solar cell system. Furthermore, the sensor is directly exposed to the external environment and is susceptible to interference and damage, making it impossible for the sensor to sense the correct position of the sun. Invention disclosure

An object of the present invention is to provide a concentrating module, which can solve the problem that the prior art can only absorb light in a single incident direction, has a complicated structural design, and is susceptible to interference and damage of the sensor, and causes a sensing error. The use area of the photoelectric conversion battery module can also be reduced, thereby effectively reducing the manufacturing cost of the light collection module. According to an embodiment of the concentrating module disclosed in the present invention, the concentrating module comprises a main concentrating plate, a concentrating assembly and an electric energy generating module. The main concentrator panel includes a main collection surface and a illuminating surface. The light collecting assembly includes a first surface and a second surface. The area of the first surface is greater than the area of the second surface. The main collection surface is for receiving a light, and the light exit surface emits light received by the main collection surface. The first surface receives light from the light exiting surface and the second surface emits light received by the first surface to the electrical energy generating module. The power generation module converts the energy of the light into an electrical energy. BRIEF DESCRIPTION OF THE DRAWINGS

The structural principle and working principle of the invention will be specifically described below with reference to the accompanying drawings:

Referring to FIG. 1, a schematic perspective view of a first embodiment of a light collecting module according to the present invention is shown. In this embodiment, the light collecting module 100 includes a main light collecting plate 102, a light collecting assembly 104, and an electric energy generating module 106.

The main concentrator 102 includes a main concentrating surface 50 and a illuminating surface 52. The light collecting assembly 104 includes a first surface 62 and a second surface 64. The area of the first surface 62 is greater than the area of the second surface 64. The main collection surface 50 is for receiving the light 30, and the light 30 is transmitted through the main collection plate 102. The light exit surface 52 emits the light 30 received by the main collection surface 50, as shown in Fig. 2A. The first surface 62 receives the light 30 from the light exiting surface 52, causing the light 30 to pass through the light collecting assembly 104. The second surface 64 projects the light 30 received by the first surface 62 to the electrical energy generation module 106. The power generation module 106 converts the energy of the incident light 30, such as light energy or thermal energy, into electrical energy. In order to avoid the complexity of the drawing, the light 30 is not drawn in Figure 1.

Referring to FIG. 2A, the main collection surface 50 can include a plurality of first microprism structures 90. The plurality of first microprism structures 90 are arranged along the first direction P. The first direction P is the direction from the light exit surface 52 to the first surface 62. Each of the first microprism structures 90 includes a first light-incident surface 92 and a first backlight surface 94. The first direction P is perpendicular to a normal 32 that is perpendicular to the main collection surface 50. Each first microprism structure 90 satisfies the following conditional formula:

0° ≤ α ≤ 40°;

45°≤β<90° _ο

Where α is the first angle between the first brightness-on surface 92 and the normal 32, and β is the second angle between the first backlight surface 94 and the normal 32.

The light ray 30 received by the main concentrator 102 has a third angle 与 with the normal 32, and the third angle Θ can be greater than or equal to 45 degrees and less than 90 degrees (i.e., 45° θ < 90°).

The following is a light collecting experiment using the main light collecting plate 102 of the above embodiment. Please refer to Table 1, for the first microprism structure to have a different percentage of the first angle α and the second angle β. The percentage of light output is the percentage between the intensity of the light emitted from the light exiting surface 52 and the intensity of the light incident on the main light collecting surface 50.

Table 1

It can be seen from Table 1 that when 0 ° ^ α ^ 40 ° and 45 ° ^ β < 90 °, the percentage of light output is greater than zero. In other words, when the first angle α and the second angle β satisfy the above conditions, the main concentrator 102 has a collecting mechanism.

In addition, the light ray 30 received by the main collection surface 50 has a third angle Θ between the normal line 32, and the third angle Θ can be greater than or equal to 45 degrees and less than 90 degrees (ie, 45° ^ θ<90°). .

Referring to FIG. 1, since the area of the first surface 62 is larger than the area of the second surface 64, the light collection ratio of the light collection module 100 is increased, thereby improving the power conversion efficiency of the power generation module 106. The above collection ratio satisfies the following formula (:1)

_T A cos (9

L =— x

^C " (1) Where L is the concentrating ratio, A is the area of the main concentrating surface 50, C is the area of the second surface 64 (ie, the illuminating area of the electric energy generating module 106), and η is the optical transmission efficiency of the concentrating module 100 (ie, The percentage of light 30 incident between the primary collection surface 50 and the intensity of light transmitted to the electrical energy generation module 106).

In the present embodiment, the light collecting assembly 104 can include a single light collecting unit 70. The light collecting unit 70 has a first surface 62 and a second surface 64, but this embodiment is not intended to limit the present invention. For example, the light collecting component 104 can also include two light collecting units. It should be noted that when the number of light collecting units increases, the light 30 may lose part of the light intensity due to the process of multiple passes, thereby affecting the light transmission efficiency η of the light collecting module 100.

In the present embodiment, the first surface 62 may also include a plurality of second microprism structures 63. The plurality of second microprism structures 63 are arranged along a second direction S, as shown in FIG. 2A, which is an enlarged schematic view of a side view structure of an embodiment of the light collecting assembly and the electric energy generating module according to FIG. Each of the second microprism structures 63 includes a second mating surface 631 and a second backlight surface 632. The second direction S is perpendicular to a vertical line 71 perpendicular to the first surface 62. Each of the second microprism structures 63 satisfies the following conditional formula:

0 ^ο ≤α'≤40 ^ο _; and

45° ≤ β' <90° ο

Where α' is the fourth angle between the second face-up face 631 and the vertical line 71, and β' is the fifth angle between the second backlight face 632 and the vertical line 71.

The light ray 30 received by the light collecting unit 70 has a sixth angle γ with the vertical line 71, and the sixth angle γ can be greater than or equal to 45 degrees and less than 90 degrees (i.e., 45° γ < 90°). Since the design of the second microprism structure 63 is the same as the design of the first microprism structure 90, and the angle range of the light received by the light collecting unit 70 is the same as the angle range of the light 30 received by the main light collecting plate 102, the light collecting is performed. Unit 70 also has a light collecting function.

Referring to FIG. 3, a perspective view of a second embodiment of a light collecting module according to the present invention is shown. In this embodiment, the light collecting module 200 includes a main light collecting plate 202, four light collecting assemblies 204, and four electric energy generating modules 206.

The sub-glossy surfaces 21, 22, 23, 24 intersect at a center point Q, but this embodiment is not intended to limit the invention. In another embodiment, the number of the light-emitting surface, the second light-collecting surface, the light-collecting component, and the electric energy generating module may be five, and the main light collecting plate is a pentagonal light collecting plate, which can be adjusted according to actual needs.

It should be noted that the number of the light-emitting surface, the second light-collecting surface, the light collecting component and the power generating module need to be the same, and the number of the second light collecting surface, the light collecting component and the power generating module is related to the number of the light emitting surface. In other words, the sub-collective surfaces 21, 22, 23, 24 correspond to the light-emitting surfaces 11, 12, 13, 14, respectively, and the light-emitting surfaces 11, 12, 13, 14 correspond to the four light-collecting components 204, respectively, and the four light-collecting components. 204 corresponds to the four power generation modules 206, respectively.

In this embodiment, the secondary concentrating surfaces 21, 22, 23, 24 can receive the light rays 34 from the incident direction A, the incident direction 8, the incident direction C, and the incident direction D, respectively, but this embodiment is not intended to limit the present invention. . Each of the first surfaces 66 receives light rays 34 from the corresponding light exiting surfaces 11, 12, 13, 14. Each of the second surfaces 68 emits light rays 34 corresponding to the first surface 66 to the corresponding power generation module 206. Each of the electrical energy generating modules 206 converts energy from the light 34 corresponding to the second surface 68 into electrical energy. In order to avoid the complexity of the drawing, the light 34 is not drawn in FIG.

In the present embodiment, the light rays 34 received by the secondary light collecting surfaces 21, 22, 23, 24 are perpendicular to a normal 58 of the main collecting surface 54 (or the secondary collecting surfaces 21, 22, 23, 24). There is a seventh angle γ', and the seventh angle γ' can be greater than or equal to 45 degrees and less than 90 degrees (ie 45° ^ γ' <90°).

The second light collecting unit 96 is disposed beside the first light collecting unit 95. In detail, the fourth surface 69 of the second light collecting unit 96 is disposed opposite to the third surface 67 of the first light collecting unit 95. The light 34 received by the light collecting component 204 is received by the first surface 66 of the first light collecting unit 95, and is then received by the first light collecting unit 95. The unit 95 is delivered and the first light collecting unit 95 is emitted by the third surface 67. Thereafter, the light 34 is received by the fourth surface 69 of the second light collecting unit 96 and transmitted in the second light collecting unit 96 and is emitted by the second surface 68.

In this way, the concentrating module 200 can utilize the design of the serial connection of the first concentrating unit 95 and the second concentrating unit 96 (ie, the path of the ray 34 travels first through the first concentrating unit 95 and then through the second The light collecting unit 96) enhances the light collecting ratio of the secondary collecting surfaces 21, 22, 23, and 24 in the light collecting module 200, thereby effectively improving the power conversion efficiency of each of the electric energy generating modules 206.
