LED lighting is gradually replacing traditional lighting fixtures, and the cost is also decreasing. In order to increase the added value of products, manufacturers have arranged, Rio Tinto intelligent lighting market.
In view of this, the electronic lighting enthusiasts produced the "EE Design series of white papers intelligent lighting design strategy collection", in order to provide a reference platform for engineers to design more common intelligent lighting, such as drive, communication, MCU and other main chip solutions.

The white paper "Intelligent Lighting Design Raiders Collection" is divided into four parts, including design reference professional materials, original parameter analysis, complete design appreciation, design common sense decomposition, design specifications, industry standards and other rich content. And the latest and hottest design resources, is a perfect design resource document for intelligent lighting design, designed to spread and promote advanced design concepts, help engineers effectively solve various problems encountered in the design.
LED driver
The LED driving Power Supply is a power converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Generally, the input of the LED driving power source includes high-voltage power frequency alternating current (ie, commercial power), low-voltage direct current, high-voltage direct current, low voltage high. Frequency communication (such as the output of an electronic transformer). However, the output of the LED driver power supply is mostly a constant current source that can change the voltage as the LED forward voltage drop value changes. Therefore, in the field of LED lighting, in order to reflect the characteristics of LED lamp energy saving and long life, it is very important to correctly select the LED driver IC. Without the matching of good driver ICs, the advantages of LED lighting cannot be realized.
Communication
The intelligent lighting control system is a control system that integrates multiple control methods, modern digital control technology, network technology and lighting technology. Intelligent lighting control systems can be divided into wired intelligent lighting control systems and wireless intelligent lighting control systems. Wired intelligent lighting usually uses a pair of twisted pairs as the communication medium. All system control units are connected by the pair of twisted pairs to form a control network for intelligent network control. Wireless control makes people's lives more comfortable. The control signals emitted by each system control unit of such a system are propagated by radio waves, thereby implementing intelligent network control.
MCU/controller
With the increasing popularity of light-emitting diodes (LEDs), applications are becoming more diverse, and the business opportunities of intelligent lighting systems are more and more expected by the industry. In order to make the lighting system intelligent, the LED luminaire is introduced into the microcontroller (MCU), which can realize automatic brightness adjustment, automatic color conversion, environment sensing, and group system control, enriching the application of LED, and Improve energy efficiency. Since the beginning of this year, the trend of intelligent dimming has become more popular and expanded. It has also directly promoted the innovation and development of LED driver ICs with intelligent control functions. Various LED driver IC manufacturers have begun to pay attention to the intelligent development of their products.
