Method for calculating the functional efficiency of solar street light and lawn light

In recent years, solar street lights and LED lawn lights in the Chinese market have been widely used in various fields. Their purpose is to increase the light source efficiency in the commercial lighting field from the current 301m/W to more than 5 times. The highest state of lamps and lanterns, 'shadowless lamp' is also the highest technology embodiment of humanized lighting. There is no trace of common lamps, so people can feel the light but cannot find the light source, which reflects the humanized design of the perfect combination of light and human life. A common warm white package LED is used as the lighting source. The rated index of the LED is 3000K (CCT) 350mA, 3.8V (maximum forward voltage drop). Under the test conditions, the LED junction temperature is 25°C, and the current pulse action time is 25ms. In the actual working process, the junction temperature of the LED will rise to a certain stable value according to the thermal design of the lighting fixture. For any solar street light and LED lawn light, the brightness generated by the rise in air temperature will decrease. Compared with the test value, the brightness of the LED operating at 60°C will be reduced by 10%. This means that the actual brightness generated by the LED is 541m in a stable working state. The two primary colors solar street light and LED lawn light can realize the continuous transformation and selection of brightness and grayscale color, so that the lighting can be expanded from white light in the general sense to light of various colors. to create different indoor and outdoor lighting effects. Among them, the switch driver is the one that achieves the best effect, which is generally between 8026 and 85%. To achieve higher energy efficiency, more complex and stable circuits are required, so the cost of the driver is higher. In order to achieve more energy-saving and brighter LED lights. As a professional solar street light manufacturer, we are constantly innovating and developing in science and technology, hoping to get a wide range of applications and development.
