Analysis of LED lighting fixtures and sensor technology 2

Wind and solar LED street lights are highly intelligent and unmanned road lighting fixtures that generate electricity from wind and sunlight, and store energy in batteries. Therefore, automatic energy management is crucial. A photosensitive sensor is an ideal electronic sensor that can control the circuit to automatically switch on and off due to changes in illumination during dawn and dusk (sunrise, sunset). Figure 2 shows the appearance of a photosensitive sensor. Figure 3 shows the photoresistor plate of the photosensitive sensor, which is highly sensitive to the brightness of light. Figure 4 is the basic principle diagram of photoelectric conversion. The working principle of the light controlled LED lighting system is shown in Figure 1.diode

A photosensitive sensor that can automatically control the opening and closing of LED lighting fixtures in shopping malls based on weather, time period, and region. By reducing its output power during bright daylight hours, a convenience store with a store area of 200m2 can reduce power consumption by up to 53% compared to using fluorescent lamps. The lifespan is also about 50000 to 100000 hours. In general, the lifespan of LED lighting fixtures is around 40000 hours; The glowing colors can also be transformed into RGB colors to make the mall lighting more colorful and the atmosphere more lively; Compared with the original blue LED that uses a phosphor, the purple LED that uses red, green, and blue phosphors has higher color rendering performance.diode
