It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
如图1所示，本发明包括电源、电光转换装置、光电转换装置，电源与电光转换装置电连接、电光转换装置与光电转换装置光连接。电光转换装置，将电源输入的电能转换成光能输出，产生能量光源。通过光密闭的传输路径将电光转换装置产生的光能全部传送给光电转换装置，光电转换装置将输入的光能转换成电能输出给负载，实现电-光-电的能量转换。其中，电光转换装置可采用发光二极管或激光器实现，光电转换装置可采用太阳能电池等硅板实现。As shown in FIG. 1 , the present invention includes a power supply, an electro-optical conversion device, and a photoelectric conversion device. The power supply is electrically connected to the electro-optic conversion device, and the electro-optic conversion device is optically connected to the photoelectric conversion device. The electro-optic conversion device converts the electric energy input by the power supply into light energy output to generate an energy light source. All the light energy generated by the electro-optical conversion device is transmitted to the photoelectric conversion device through the light-tight transmission path, and the photoelectric conversion device converts the input light energy into electrical energy and outputs it to the load, realizing the energy conversion of electricity-optical-electricity. Wherein, the electro-optic conversion device can be realized by light emitting diode or laser, and the photoelectric conversion device can be realized by silicon plate such as solar cell.
本发明中电光转换装置包括多个贴片高亮度发光二极管组成的LED面光源装置，光电转换装置包括太阳能电池板，LED面光源装置与太阳能电池板通过结构件平行安装；当LED面光源装置加电源发光时，太阳能电池板吸收LED面光源装置的光能，产生电压和电流，实现电-光-电的能量转换。In the present invention, the electro-optical conversion device includes an LED surface light source device composed of a plurality of patch high-brightness light-emitting diodes, the photoelectric conversion device includes a solar panel, and the LED surface light source device and the solar panel are installed in parallel through structural members; When the power supply emits light, the solar panel absorbs the light energy of the LED surface light source device, generates voltage and current, and realizes the energy conversion of electricity-light-electricity.
设计中，根据负载对电源功率的要求，选择满足能量输出要求的太阳能电池板，同时，根据所选择的太阳能电池板对光能的需要，若采用LED面阵光源作为电光转换装置，则设计LED面阵光源和LED面阵光源所需的电源；若采用激光器作为电光转换装置，则选择相应匹配于激光器的电源。In the design, according to the requirements of the load on the power supply, select a solar panel that meets the energy output requirements. At the same time, according to the needs of the selected solar panel for light energy, if the LED area array light source is used as the electro-optical conversion device, then design the LED The power required for the area array light source and LED area array light source; if a laser is used as the electro-optic conversion device, select a power supply that matches the laser.
LED面阵光源的设计如图2，定义相邻两个LED间距为d，LED面阵光源与太阳能电池板间距为h，LED的光照角度为θ，理想状况下，这三个参数关系满足公式d＝2×h×tg(θ/2)。通过选定的LED特性可确定θ值，并根据LED光强与距离的关系确定合适的h值。根据计算出的d值和太阳能电池板的形状可计算出所需LED的个数，使面阵光源的光照射范围覆盖整个太阳能电池板的有效电池面积。根据计算LED的个数，将发光二极管按照合适的串并联方式连接，若计算后每行有n个LED，每列有m个LED，每个LED放光所需要的电压为xV，所需要的电流为ymA，可将每行的LED选择n1个为一组进行串联，再将每行串联后的n个LED并联，共并联(n/n1)*m路，得到给每路串联的n1个LED提供电压(x*n1)V，电流ymA，则并联(n/n1)*m路所需的LED电源功率为电压(x*n1)V，电流(y*m*n/n1)mA。假设太阳能电池板为方形，长为L，宽为W，则LED面阵光源也设计成方形阵列，每行(W/d)个LED，每列(L/d)个LED，根据适合的串-并连接，设计LED电源。例如，经过计算后每行10个LED，每列6个LED，每个LED发光需要2V/10mA，可将每行的5个LED串联，再将每行串联后的5个LED进行并联，共并联12路；则需要给每路串联的5个LED提供10V/10mA电源，并联12路所需的LED电源功率为10V/120mA。The design of the LED area light source is shown in Figure 2. The distance between two adjacent LEDs is defined as d, the distance between the LED area light source and the solar panel is h, and the illumination angle of the LED is θ. Ideally, the relationship between these three parameters satisfies the formula d=2×h×tg(θ/2). The θ value can be determined through the selected LED characteristics, and the appropriate h value can be determined according to the relationship between LED light intensity and distance. According to the calculated d value and the shape of the solar panel, the required number of LEDs can be calculated, so that the light irradiation range of the area array light source covers the effective battery area of the entire solar panel. According to the calculated number of LEDs, connect the light-emitting diodes in an appropriate series-parallel manner. If there are n LEDs in each row and m LEDs in each column after calculation, the voltage required for each LED to emit light is xV, and the required The current is ymA, you can select n1 LEDs in each row as a group for series connection, and then connect n LEDs in parallel in each row, and connect (n/n1)*m circuits in parallel to obtain n1 LEDs in series for each circuit. The LED provides voltage (x*n1)V and current ymA, then the LED power required for parallel (n/n1)*m circuits is voltage (x*n1)V and current (y*m*n/n1)mA. Assuming that the solar panel is square, the length is L, and the width is W, the LED area array light source is also designed as a square array, with LEDs in each row (W/d) and LEDs in each column (L/d). - and connected, design the LED power supply. For example, after calculation, there are 10 LEDs in each row and 6 LEDs in each column. Each LED requires 2V/10mA to emit light. You can connect 5 LEDs in each row in series, and then connect the 5 LEDs in parallel in each row. 12 channels connected in parallel; it is necessary to provide 10V/10mA power supply to each of the 5 LEDs connected in series, and the required LED power supply for 12 channels connected in parallel is 10V/120mA.
