Description

Sunlight control device for solar illumination and energy generation

[ technical field ] A method for producing a semiconductor device

The present invention relates to a light control device, and more particularly to a daylight control device for lighting and energy generation.

[ background of the invention ]

The utility model discloses solar energy belongs to the clean energy and gets inexhaustibly, therefore how effectively to utilize solar energy for the main research and development direction of each world. At present, the main application mode of solar energy is not the application of power generation, heating or illumination and the like. In order to effectively utilize solar energy, a conventional solar cell is often installed in a space where sunlight can be directly emitted, for example, outdoors.

Solar devices are largely divided into two categories. One is a photovoltaic (photovoltaic) system equipped with a solar array of solar panels that absorb sunlight and convert it into electrical energy, a solar inverter (inverter) that converts current from Direct Current (DC) to Alternating Current (AC), and other installations, wiring, and other electrical accessories to create a working system. The solar array of such solar panels receives no concentrated sunlight and the lifetime of the solar panels arranged outdoors may be shortened due to climatic factors. Another type is Concentrated Photovoltaics (CPV), also known as concentrated Photovoltaics, which use lenses and curved mirrors to focus sunlight to small, high-efficiency, multi-junction (MJ) solar cells. Although concentrated photovoltaic is a highly efficient multi-junction solar cell, photovoltaic systems of solar panels are gaining popularity worldwide because of other factors.

However, most conventional solar panels are designed to be large-area sunlight-facing arrangements that facilitate absorption of solar energy. The installation of such solar panels shields too much sunlight to block scattered (or so-called diffuse) solar radiation to the area behind the solar panel. Moving large area solar panels is another way to let sunlight radiate to the area behind the solar panels, but such large devices are not easily moved. Furthermore, in the case where the power consumption for illumination is larger than the solar power generation amount, introduction of sunlight illumination is apparently better for energy utilization. After all, the process of light-to-electricity followed by electrical-to-light energy transfer for artificial lighting should be avoided, since energy conversion would result in energy efficiency loss.

When considering sunlight to provide illumination to a person or plant, direct sunlight is often very intense and causes people to feel dazzling and the plant to quickly wither. Furthermore, when direct sunlight passes through the cover or space between covers to an area under the cover or cover, it often produces a distinct beam of light that is brighter than the area surrounding it and is not suitable for plant growth and people in the area.

In view of the above, how to regulate sunlight to effectively use solar energy is an urgent objective of efforts.

[ detailed description ] embodiments

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. Aside from the specific details disclosed herein, this invention is capable of other and general embodiments and its several details are capable of modifications in various obvious respects, all without departing from the scope of the invention. In the description of the specification, numerous specific details are set forth in order to provide a thorough understanding of the present invention; however, the present invention may be practiced without some or all of these specific details. In other instances, well-known steps or elements have not been described in detail so as not to unnecessarily obscure the present invention. The same or similar elements in the drawings will be denoted by the same or similar symbols. It is to be expressly noted that the drawings are for illustrative purposes only and do not represent actual sizes or quantities of elements. Some of the details may not be fully drawn in order to simplify the drawing.

Referring to fig. 1, the sunlight control apparatus according to the first embodiment of the present invention includes a light focusing module 11 and a light deflecting module 12. Typically, incident sunlight includes both direct radiation and diffuse radiation. The direct radiation is also referred to as direct sunlight SL1 and the diffuse radiation is also referred to as diffuse sunlight SD 1. The light focusing module 11 may focus direct sunlight SL1 onto a focal area 10. Direct sunlight SL1 from sunlight (not shown) may be focused through light focusing module 11 into focal area 10. In the first embodiment, the light focusing module 11 may be a fresnel lens, but is not limited thereto. The function that other lenses have convergent light can also realize the utility model discloses. In addition, the sunlight incident through the light focusing module 11 may be focused at one point or one line within the focusing area 10 through the light focusing module 11. Next, the light-deflecting module 12 is arranged on or adjacent to the focal area 10 of the concentrated direct sunlight SL 1'. The light deflecting module 12 reflects direct sunlight SL1' to form reflected sunlight SL2 to divergently reach a target area 20. Wherein the target area 20 is offset from the optical axis a of the light focusing module 11. In one embodiment, the light deflecting module 12 may be a reflective element or a refractive element. In the embodiment shown in fig. 1, the light deflecting module 12 is a reflective element. It is understood that the light deflecting module 12 may be a single optical element, which may include multiple reflective or refractive surfaces. For example, the light deflecting module 12 may be a prism. In addition, the position of the sun varies with time, and the focal region moves accordingly. Therefore, in one embodiment, the size or the movable path of the light deflecting module 12 covers the moving track of the focusing area.

With continued reference to fig. 1, in one embodiment, a light incident surface of a solar panel or a heating device (not shown) may be disposed in the target area 20 to utilize the divergent reflected sunlight SL2 reflected by the light deflecting module 12. According to the embodiment shown in fig. 1, the sunlight control device of the present invention is used to adjust the light path of the direct sunlight SL1, and the arrangement of the solar panel and/or the heating device is more flexible. For example, the solar panel can be disposed in a shielded environment, so that the service life of the solar panel can be prevented from being shortened due to weather factors such as wind, rain and the like. In addition, the solar panels may be arranged in an upright manner to reduce the space required for mounting the solar panels and/or the heating device. Moreover, the divergent reflected sunlight SL2 may be more divergently diffused than the convergent direct sunlight SL1', so that the solar panels and/or heating devices may have a greater height but occupy a smaller horizontal area in the target area 20. Therefore, most of direct sunlight can be incident into the sunlight control device and utilized through the solar panel or the heating device.

With continued reference to FIG. 1, the diffuse daylight SD1, after passing through the light focusing module 11, is designated as diffuse daylight SD 2. Diffuse daylight SD2 passes further through light bending module 12 to the area under light focusing module 11. The diffuse daylight SD2 may be used to illuminate the area under the light focusing module 11. Thus, the light bending module 12 is configured and separates the diffuse daylight SD1 of the incident daylight and the concentrated direct daylight SL1 'by reflecting the concentrated direct daylight SL 1'.

In a different aspect of the second embodiment of the present invention, as shown in fig. 2a and 2b, the light focusing module comprises a linear fresnel lens 21 for receiving incident direct sunlight SL1 and incident diffuse sunlight SD 1. Incident direct sunlight SL1 is incident on one side of linear Fresnel lens 21 and passes through linear Fresnel lens 21 and forms direct sunlight SL1' on the other side of linear Fresnel lens 21. In the second embodiment, people or plants 31 on the ground 40 are located under the linear Fresnel lens 21 and on the other side of the linear Fresnel lens 21, as is direct sunlight SL1' and diffuse sunlight SD 2. Because of the good light transmission of the linear fresnel lens 21, the diffused sunlight SD2 can reach and be distributed on the other side of the linear fresnel lens 21, i.e. the area where the plants 31 are located or inhabit. Next, a light deflecting module 12 having a plurality of reflecting surfaces with different angles is disposed on or in the focusing area 10, and the light deflecting module 12 is used to reflect the direct sunlight SL1' to form the divergent reflected sunlight SL 2. The divergent reflected sunlight SL2 may reach the target area 20 where one or more solar panels 25 are installed, so that the solar panels 25 may utilize reflected sunlight SL2 that is not focused.

Referring to fig. 2a, with light-deflecting module 12 placed directly at or on the focal point or line of focus of focal region 10 or within focal region 10, the smaller size of light-deflecting module 12 may reflect most of direct sunlight SL1', and most of diffuse sunlight SD2 may not be obscured by light-deflecting module 12 located below linear fresnel lens 21. On the other hand, most of the diffuse daylight SD2 located below the linear Fresnel lens 21 may reach the floor 40 and provide the desired illumination area 30 for people and/or plants 31. Thus, the cooperation of the linear fresnel lens 21 and the light deflecting module 12 may utilize direct sunlight SL1' and diffuse sunlight SD2, respectively, in different applications, such as photovoltaic solar panels 25 to generate electricity and illumination of plants 31 or people. Also, because of the diffuse daylight SD2, the brightness of the illumination area 30 is uniform rather than glare.

On the other hand, referring to fig. 2b, the light deflecting module 12 having a plurality of reflecting surfaces with different angles may be disposed obliquely in different seasons. In the case where direct sunlight SL1 is incident on linear Fresnel lens 21 at different angles of incidence during different seasons, direct sunlight SL1' is incident on light deflection module 12 at different angles of incidence. The light deflecting module 12 of the second embodiment may be arranged at different angles or shapes or sizes to receive the concentrated direct sunlight SL 1'. Direct sunlight SL1' is then reflected to target area 20. On the other hand, diffuse daylight SD2 is still illuminated by light-deflecting module 12 to illumination area 30. Thus, light-deflecting module 12, either sized or having an adjustable orientation, may accommodate direct sunlight SL1' that may converge on focal region 10 during different seasons. The size and/or shape of light deflecting module 12 may also be used to control the amount of diffuse daylight SD2 passing through light deflecting module 12 for illuminating illumination area 30 located below linear fresnel lens 21. The light deflecting module 12 then has multiple reflecting flat or curved faces of different angles, which may be a single piece or connected piece or a component consisting of different separate pieces or having a reflecting function.

Therefore, compare with the typical design that is used for the conversion of solar energy, the utility model discloses a sunlight regulation and control device's setting can not shelter from the area behind the sunlight regulation and control device that the sunlight radiates, and the area behind the sunlight regulation and control device still is passed moreover the utility model discloses sunlight regulation and control device's sunlight is shone. In one aspect, the present invention provides a daylight control device that can provide diffuse daylight for direct illumination without the need for a light-to-electricity and light-to-electricity energy conversion process. On the other hand, the utility model discloses a sunlight regulation and control device can deviate and spread and penetrate direct sunlight and be used for providing sunshine and need not occupy the footprint that extra area set up solar panel or other equipment in addition for solar panel or other equipment.

Fig. 3 and 4 illustrate a third and a fourth embodiment of the daylight control apparatus of the present invention, respectively. Referring to fig. 3 and 4, a driving element 13 is connected to the light deflecting module 12 for driving the light deflecting module 12 to operate in a rotational manner (as shown in fig. 3), a linear movement manner (as shown in fig. 4) or a combination thereof. Deviating from the focus area 10 with the light-deflecting module 12 driven by the driving element 13, the concentrated direct sunlight SL1' is not deflected by the light-deflecting module 12 to the target area 20, but illuminates the illumination area 30 after passing through the focus area 10 from the light-focusing module 11, in addition to which diffused sunlight SD2 illuminates the illumination area 30. It will be appreciated that the degree to which light deflecting module 12 is offset from the focal region 10 may still be such that a portion of the concentrated direct sunlight SL1' is reflected to form divergent reflected sunlight SL2 that is directed to target area 20 for illumination purposes.

Fig. 5 illustrates a fifth embodiment of the daylight control apparatus of the present invention. In a fifth embodiment, the light deflecting module 12 comprises a plurality of optical elements 121, 122. As shown in fig. 5, the optical element 122 includes a curved surface to adjust the divergence of the concentrated direct sunlight SL1' reflected from the optical element 122. Alternatively, the light deflecting module 12 comprising a single optical element having a curved surface can also perform the function of further converging and diverging the reflected sunlight SL 2.

Fig. 6 illustrates a sixth embodiment of the daylight control apparatus of the present invention. Compared to the fifth embodiment shown in fig. 5, the sixth embodiment further comprises a driving element 13 connected to the optical element 121 of the light deflecting module 12. Similar to that shown in fig. 3 and 4, the driving element 13 is configured to drive the optical element 121 in a rotational or linear motion away from the focal area of the light focusing module 11, such that the concentrated direct sunlight SL1' is spread through the focal area for illumination purposes. It is understood that the same objective as described above can be achieved by using the driving element 13 to drive the light deflecting module 12 including the optical elements 121 and 122 to deviate from the focusing area of the light focusing module 11. In one embodiment, the driving element 13 may drive the optical element 121 to rotate to converge and deflect the direct sunlight SL1' through the light focusing module 11 to other directions for illuminating a broader target area 20, rather than to the optical element 122.

Next, as shown in fig. 7a and 7b, a seventh embodiment of the present invention further includes at least one filter element 14 and a scattering element 15. The filter element 14 and the scattering element 15 are selectively movable in a linear motion or in a rotational manner to the focus region or to the vicinity thereof by means of a drive element (not shown in fig. 7a and 7 b). According to the above structure, for example, for illumination purposes, the filter element 14 or the scattering element 15 can be moved to the focus region to filter or scatter the concentrated direct sunlight SL1' for better illumination effect.

Next, as shown in fig. 8, a plurality of light focusing modules and light deflecting modules are used in the eighth embodiment of the present invention. The light focusing module 11a corresponds to the light deflecting module 12a, and the light focusing module 11b corresponds to the light deflecting module 12 b. Further, the plurality of light focusing modules and light deflecting modules may reflect concentrated daylight SL1' to form reflected daylight SL2 on the same target area 20. According to this structure, more sunlight can be obtained per unit area of the target area 20.

Next, as shown in fig. 9, the light focusing module 17 is an asymmetric focusing optical system element. Briefly, the focusing area of the light focusing module 17 is deviated from the physical central axis C of the light focusing module 17. Therefore, the set position of the light deflecting module 12 is deviated from the physical central axis C of the light focusing module 17, which may more flexibly improve the assembly of the light focusing module 12.

Referring to fig. 9, in an embodiment, the light deflecting module 12 may be an a-reflection filter. In other words, first light rays WL1 having a first wavelength range in the concentrated sunlight may be deflected to target area 20 by light-deflecting module 12, and second light rays WL2 having a second wavelength range in the concentrated sunlight pass through light-deflecting module 12. According to this structure, the second light WL2 can be used to illuminate or illuminate plants to promote plant growth or human beings, and the first light WL1 can be used to generate electricity or heat. It is understood that the first light ray WL1 may not be directed to the target area 20 at any destination.

Fig. 10 is a perspective side view schematic of a daylight conditioning apparatus according to the present invention. In one embodiment, one or more linear Fresnel lenses 51 are used as a light focusing module to pass and focus direct sunlight SL1 in one dimension. One or more light deflecting modules 12 are disposed on or adjacent to the focal area and converge direct sunlight SL 1. The illumination area 30 for the plant 31, human or animal is located below the linear fresnel lens 51, and the solar panel 52 of the target area is arranged perpendicular to the linear fresnel lens 51 at a distance equal to the width of the linear fresnel lens 51. The area of the solar panel 52 may be larger than the linear fresnel lens 51 to receive reflected sunlight that is divergently reflected by the light deflecting module 12. In practice, the angle of incidence of the direct sunlight SL1 varies across the linear Fresnel lens 51 not only throughout the day, but also during different seasons. In designs not designed for solar tracking, the back side of the solar panel 52 may be coated with a reflective material to reflect the oblique direct sunlight SL1 while the direct sunlight SL1 is still oblique after being focused by the linear fresnel lens 51 to reflect off of the light deflecting module 12. Thus, when a plurality of solar panels 52 are properly arranged, the reflective back side of the solar panels 52 may be considered as part of the light deflecting module 12. The daylight control apparatus of the present invention shown in fig. 10 may be implemented such that the focal line of direct sunlight SL1 on light deflection module 12 may move along multiple light deflection modules 12 during the day or during different seasons. Therefore, the quality of the focusing line shape due to the variation of different incident directions caused by different seasons and the oblique incidence can be solved. The utility model discloses a sunlight regulation and control device can install the roof of people's building or the greenhouse of plant.

In summary, the sunlight control apparatus of the present invention uses the light focusing module and the light deflecting module to adjust the light path of the incident sunlight and guide the sunlight to the target area, so as to more flexibly and conveniently install the solar panel and/or the heating apparatus, for example, in a shielded environment or vertically. In addition, the light path of the incident sunlight can be changed by controlling the light focusing module or the light deflecting module so that the applied sunlight can be selectively adjusted.

The above-mentioned embodiments are only for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and the scope of the present invention should not be limited by the claims, i.e. all equivalent changes or modifications made according to the spirit disclosed by the present invention should be covered by the scope of the present invention.
