具有球面透镜的太阳能系统 Solar System with Spherical Lens

技术领域 technical field

本发明涉及一种太阳能系统，更明确地说，涉及一种具有球面透镜的太阳能系统。The present invention relates to a solar energy system, and more particularly to a solar energy system having a spherical lens.

背景技术 Background technique

参看图1，其展示第一常规太阳能系统10。所述第一常规太阳能系统10包含：一透镜11和一太阳能板12。所述透镜11用于从太阳18接收太阳光16并透射集束光17。所述太阳能板12用于接收所述集束光17。通过利用透镜11，可减小太阳能板12的面积以节省空间。然而，太阳18并不总是在透镜11的正上方位置。如果太阳18移动到太阳能板12的左侧或右侧，那么太阳能板12无法从透镜11接收到集束光17。所述第一常规太阳能系统10的利用率不佳。Referring to FIG. 1 , a first conventional solar energy system 10 is shown. The first conventional solar system 10 includes: a lens 11 and a solar panel 12 . The lens 11 is used to receive sunlight 16 from the sun 18 and transmit concentrated light 17 . The solar panel 12 is used to receive the concentrated light 17 . By using the lens 11, the area of the solar panel 12 can be reduced to save space. However, the sun 18 is not always in a position directly above the lens 11 . If the sun 18 moves to the left or right of the solar panel 12 , the solar panel 12 cannot receive the concentrated light 17 from the lens 11 . The utilization rate of the first conventional solar energy system 10 is poor.

参看图2，其展示第二常规太阳能系统20。所述第二常规太阳能系统20包含：一透镜21、一太阳能板22和一马达23。所述透镜21用于从太阳28接收太阳光26并透射集束光27。所述太阳能板22用于接收集束光27。由于第一常规太阳能系统10的上述缺点，因而第二常规太阳能系统20利用马达23来驱动透镜21和太阳能板22使其跟随太阳28的移动而移动。因此，太阳28总是在透镜21的正上方位置，且太阳能板22可接收集束光27。然而，所述马达23将消耗电能，并减小第二常规太阳能系统20的总效率。Referring to FIG. 2 , a second conventional solar energy system 20 is shown. The second conventional solar system 20 includes: a lens 21 , a solar panel 22 and a motor 23 . The lens 21 is used to receive sunlight 26 from the sun 28 and transmit concentrated light 27 . The solar panel 22 is used to receive the concentrated light 27 . Due to the above-mentioned disadvantages of the first conventional solar system 10 , the second conventional solar system 20 utilizes a motor 23 to drive the lens 21 and the solar panel 22 to follow the movement of the sun 28 . Therefore, the sun 28 is always directly above the lens 21 , and the solar panel 22 can receive the concentrated light 27 . However, the motor 23 will consume electrical energy and reduce the overall efficiency of the second conventional solar system 20 .

因此，有必要提供一种太阳能系统以便解决上述问题。Therefore, it is necessary to provide a solar energy system to solve the above problems.

具体实施方式 Detailed ways

参看图3A到3D，其展示根据本发明第一实施例的具有球面透镜的太阳能系统。所述太阳能系统30包含：一球面透镜31和一太阳能板32。所述球面透镜31具有一第一表面311和一第二表面312。所述第一表面311用于在任何位置处从一光源接收入射光。所述第二表面312用于将由入射光引起的集束光透射到一预定区域。在第一实施例中，光源是太阳38。Referring to Figures 3A to 3D, there is shown a solar energy system with a spherical lens according to a first embodiment of the present invention. The solar system 30 includes: a spherical lens 31 and a solar panel 32 . The spherical lens 31 has a first surface 311 and a second surface 312 . The first surface 311 is used to receive incident light from a light source at any position. The second surface 312 is used to transmit the bundled light caused by the incident light to a predetermined area. In a first embodiment, the light source is the sun 38 .

参看图3A，太阳38移动到太阳能系统30的右侧。球面透镜31的第一表面311在第一位置处(右侧)从太阳38接收入射光361。球面透镜31的第二表面312将由入射光361引起的集束光371透射到太阳能板32。太阳能板32安装在所述预定区域上，且用于接收集束光371并产生电能。Referring to FIG. 3A , the sun 38 has moved to the right of the solar system 30 . The first surface 311 of the spherical lens 31 receives incident light 361 from the sun 38 at a first position (right side). The second surface 312 of the spherical lens 31 transmits the concentrated light 371 caused by the incident light 361 to the solar panel 32 . The solar panel 32 is installed on the predetermined area, and is used to receive the concentrated light 371 and generate electricity.

参看图3B，太阳38移动到太阳能系统30的正上方位置。球面透镜31的第一表面311在第二位置处(正上方位置)从太阳38接收入射光362。球面透镜31的第二表面312将由入射光362引起的集束光372透射到太阳能板32。太阳能板32仍在所述预定区域上，且可接收集束光372。Referring to FIG. 3B , the sun 38 is moved to a position directly above the solar system 30 . The first surface 311 of the spherical lens 31 receives the incident light 362 from the sun 38 at the second position (directly above position). The second surface 312 of the spherical lens 31 transmits the concentrated light 372 caused by the incident light 362 to the solar panel 32 . The solar panel 32 is still on the predetermined area and can receive the concentrated light 372 .

参看图3C，太阳38移动到太阳能系统30的左侧。球面透镜31的第一表面311在第三位置处(左侧)从太阳38接收入射光363。球面透镜31的第二表面312将由入射光363引起的集束光373透射到太阳能板32。太阳能板32仍在预定区域上，且可接收集束光373。Referring to FIG. 3C , the sun 38 has moved to the left of the solar system 30 . The first surface 311 of the spherical lens 31 receives incident light 363 from the sun 38 at a third position (left side). The second surface 312 of the spherical lens 31 transmits the concentrated light 373 caused by the incident light 363 to the solar panel 32 . The solar panel 32 is still on the predetermined area and can receive the concentrated light 373 .

因为球面透镜31形成为一球形，所以球面透镜可接收来自任何位置的入射光，并将集束光透射到相同预定区域。本发明的太阳能系统30不需要被驱动以跟随太阳38来移动，且不需要任何其它电消耗。预定区域上的太阳能板32可一直从球面透镜31接收到集束光。因此，本发明的太阳能系统30的效率较高。Since the spherical lens 31 is formed in a spherical shape, the spherical lens can receive incident light from any position and transmit the concentrated light to the same predetermined area. The solar system 30 of the present invention does not need to be driven to follow the sun 38 to move, and does not require any other consumption of electricity. The solar panel 32 on a predetermined area may always receive the concentrated light from the spherical lens 31 . Therefore, the efficiency of the solar system 30 of the present invention is relatively high.

参看图3A到3D，太阳能板32包含一第一接收表面321和一第二接收表面322。所述第一接收表面321和所述第二接收表面322可从球面透镜31接收集束光。第二接收表面322对应于第一接收表面321。对应于一预定水平面34，第一接收表面321面朝上，且第二接收表面322面朝下。Referring to FIGS. 3A to 3D , the solar panel 32 includes a first receiving surface 321 and a second receiving surface 322 . The first receiving surface 321 and the second receiving surface 322 may receive condensed light from the spherical lens 31 . The second receiving surface 322 corresponds to the first receiving surface 321 . Corresponding to a predetermined horizontal plane 34 , the first receiving surface 321 faces upward, and the second receiving surface 322 faces downward.

球面透镜31进一步包含一半球部分313和一延伸部分314。所述半球部分313安置在所述预定水平面34上方，且所述延伸部分314安置在预定水平面34下方。太阳能板32的第一接收表面321从球面透镜31的半球部分313接收集束光，如图3A到3C所示。太阳能板32的第二接收表面322从延伸部分314接收集束光，如图3D所示。根据本发明，球面透镜不限于具有半球部分和延伸部分两者，且球面透镜可仅具有半球部分而没有延伸部分。The spherical lens 31 further includes a hemispherical portion 313 and an extension portion 314 . The hemispherical portion 313 is disposed above the predetermined horizontal plane 34 , and the extension portion 314 is disposed below the predetermined horizontal plane 34 . The first receiving surface 321 of the solar panel 32 receives the concentrated light from the hemispherical portion 313 of the spherical lens 31, as shown in FIGS. 3A to 3C. The second receiving surface 322 of the solar panel 32 receives the concentrated light from the extension 314, as shown in FIG. 3D. According to the present invention, the spherical lens is not limited to having both the hemispherical portion and the extension portion, and the spherical lens may have only the hemispherical portion without the extension portion.

参看图3D，太阳38移动到预定水平面34下方。球面透镜31的第一表面311在第四位置处(预定水平面34下方)从太阳38接收入射光364。球面透镜31的第二表面312将由入射光364引起的集束光374透射到太阳能板32的第二接收表面322。由于两个接收表面321和322，因而太阳能板32可接收到更多集束光。因此，可进一步改良本发明的太阳能系统30的效率。Referring to FIG. 3D , the sun 38 moves below the predetermined horizontal plane 34 . The first surface 311 of the spherical lens 31 receives incident light 364 from the sun 38 at a fourth position (below the predetermined horizontal plane 34 ). The second surface 312 of the spherical lens 31 transmits the concentrated light 374 caused by the incident light 364 to the second receiving surface 322 of the solar panel 32 . Due to the two receiving surfaces 321 and 322, the solar panel 32 can receive more concentrated light. Therefore, the efficiency of the solar system 30 of the present invention can be further improved.

参看图4，其展示根据本发明第二实施例的具有球面透镜的太阳能系统。所述太阳能系统40包含：一球面透镜41、一太阳能板42、一能量存储装置43、一控制装置44和一发光装置45。第二实施例的所述球面透镜41和所述太阳能板42与第一实施例的球面透镜31和太阳能板32相同。所述能量存储装置43用于存储来自太阳能板42的电能。所述发光装置45用于在夜间或阴天从太阳能板42或能量存储装置43接收电能并产生光。所述控制装置44用于控制电能是否输出到发光装置45。因此，太阳能系统40可用作路灯以便节省电力且具有美学立体效果。Referring to FIG. 4 , it shows a solar system with a spherical lens according to a second embodiment of the present invention. The solar system 40 includes: a spherical lens 41 , a solar panel 42 , an energy storage device 43 , a control device 44 and a light emitting device 45 .
