1 Introduction
As a new generation of light source, LED has a series of features such as low voltage, low power consumption, small size, fast response, no pollution, high reliability and long life.
Because it produces no spectrum of ultraviolet and infrared light, it has no heat and heat radiation, and can reduce the production of carbon dioxide and other room temperature gases, so it is considered to be a true green lighting source that is environmentally friendly and energy efficient. Since the 1990s, Japan, the United States, the European Union, South Korea, China, Taiwan and other countries and regions have launched semiconductor lighting plans to promote the development of LED lighting technology. At the same time, the world's famous lighting source manufacturers are also actively involved, and alliance with semiconductor material device manufacturers, and vigorously develop the LED lighting market. Driven by numerous forces, LED lighting technology and industry have made rapid progress and gradually entered people's daily lives [1].
Green lighting is a concept put forward by the US Environmental Protection Agency in the early 1990s. The complete green lighting connotation includes four indicators: high efficiency, energy saving, environmental protection, safety and comfort. In recent years, the concept of green LED lighting has attracted people's attention. The market has also produced various types of products with LED as the light source. Intelligent lighting has also gradually received attention from everyone, especially the development of Internet of Things technology, making intelligent lighting more important. Intelligent lighting is more than just intelligent lighting to reduce energy consumption, but also covers a variety of modern technologies such as sensing, communication, and Internet of Things. This paper discusses the application of intelligent green LED lighting technology in general lighting, landscape lighting and LED display, as well as the role of microelectronic chips such as microcontrollers, sensor interface chips, wireless transceiver chips and LED driver chips in intelligent green LED lighting. .
2 Intelligent green LED lighting technology
2.1 Intelligent LED lighting technology
LED has good controllability, which can develop intelligent LED lighting technology. Intelligent LED lighting technology monitors and tracks LEDs in real time through external sensors and control circuits, and automatically and smoothly adjusts the brightness and color of LED lighting to achieve intelligence. Control the purpose of the LED. In the intelligent control software, there are complete control protocols and control methods, perfect human-machine interface, self-diagnosis and prompting of faults; in hardware, means with multiple communication capabilities, such as wireless, power carrier, visible light, infrared light .
Intelligent LED lighting technology has the following advantages: 1. Intelligent control: intelligent lighting control, improved management level and reduced maintenance costs; 2. Energy saving: through reasonable management, according to different dates, different times, different illuminances, according to each The operation of the functional area is pre-configured with illuminance; 3, beautifying the environment: good lighting design can create a warm and comfortable environment, adding to the charm of its art; 4, extending the life of the lamp: significantly reducing the lighting time of the lamp, Therefore, the life of the lamp is greatly extended; 5. Consistency of illumination: using a light-sensitive sensor, the light in the room can be kept constant; 6. Linking with other systems: intelligent lighting can be controlled with other systems, such as BA system, monitoring alarm system, garage Credit card system.
