How to increase the brightness of solar street lights?

Solar street lights use solar light as energy to convert into electrical energy to supply energy. In order to increase the lighting brightness of solar street lights, most of them use LED lamp heads as light sources. Some people call such solar street lights LED street lights or solar LED street lights, LED street lights. The light-emitting principle is to convert power into light. Currently, one of the biggest obstacles to designing bright and high-efficiency LED street lights is increasing the output power of LED street lights and rejecting their efficiency. The results of this study, however, greatly reduced the applied voltage. According to calculations, when the voltage is reduced by half, the input power is reduced by a factor of four, however, the optical power and voltage remain the same as one half. In other words, when the output power drops, the brightness of the LED increases. The researchers only input 30pw LED power to achieve 69pw LED output light efficiency as high as 230%. Any LED that functions with the same physical mechanism of intensity has a certain probability of generating photons under the action of applied voltage, electrons and holes. The researchers did not increase the probability like other studies, but with a small amount of waste heat atomic lattice vibrations occur in mobile devices to generate more electricity. The waste heat of this light-emitting process can be utilized by a small cooling LED, which operates similarly to a thermoelectric cooler. Although at room temperature, cooling is not enough to provide a practical temperature, it can be used to design some LED street lights that do not generate heat. As a heat pump solid state cooling application power generation device, this device can help.
