Analysis of LED lighting fixtures and sensor technology 1

The biggest difference between LED lighting fixtures and traditional lighting fixtures is that LED lighting fixtures are completely electronic products, while traditional lighting fixtures are only electrical products. Therefore, LED lamps can be easily associated with various types of sensors to achieve various automatic control functions such as light control and infrared control. The automatic switching of LED street lights can be easily achieved with a single photosensitive sensor; Community nighttime walkways and courtyard lighting can use infrared sensors to collect human activity information and automatically turn on and off lighting fixtures diode

Sensors, as devices for signal acquisition and electromechanical conversion, have matured in their electromechanical technology. In recent years, the rise of MEMS technology has propelled sensor technology towards miniaturization, intelligence,diode multifunctionality, and low cost. Various types of sensors such as photosensitive sensors and infrared sensors can be combined with LED lighting fixtures to form an intelligent control system. The sensors convert various physical signals collected intodiode electrical signals, which can be intelligently processed by integrated circuit AD converters, MCUs, and DA converters to control the turning on and off of LED lighting fixtures. Humans can use this to set various control requirements on the MCU, controlling the on/off time, brightness, color rendering, and colorful changes of LED lights, thereby achieving the goal of energy saving. The system diagram composed of sensors and LED lighting fixtures is shown in Figure 1. The current integrated circuit manufacturing technology can integrate AD, DA, MCU into a 5X5mm or smaller package, which is not only space saving but also very convenient to install in lamps diode
