What are the new requirements for emerging applications of LED lighting fiery LED drivers?
According to reports from market institutions, with the emergence of a large number of new applications for smart lighting, automotive headlamps and other LED applications, the 2016 LED lighting market will reach US$29.6 billion. In 2017, the LED lighting market is expected to reach US$33.1 billion. To be the LED driver of the "heart" of LED lamps, and with the rise of emerging applications, more requirements have been given. Today's LED drivers not only need to solve the problems of buck and constant current, but also require high conversion efficiency. , Smaller size, multiple protection and diagnostic functions, long working hours, lower cost and solve the problem of anti-electromagnetic interference.
Multiple needs have led to miniaturization of integrated design
With the development of LED lighting towards smart green, LED-driven miniaturization designs can help LED lamps to save space more effectively, reduce production costs, allow lamps to gain greater design freedom, and miniaturization design development is an inevitable trend; followed by As emerging LED lighting applications now require more dimming and color matching to ensure circuit safety, it is necessary to consider the ability to implement a variety of dimming and color adjustment functions while providing protection and diagnostic capabilities. This ensures that the LED lamps work well.
This means that in the face of these many new requirements and numerous LED driver solutions, the design of LED drivers will tend to be miniaturized and feature-integrated designs. They not only need to integrate different LED lamps, but also design the LED driver even more. Small, more in line with the lighting, but also to consider different situations in different environments, integrate more features.
In order to help lighting companies understand the most cutting-edge and innovative LED drive control technology and help companies find the most cost-effective LED drive solutions, on September 8th, 2017, Big Bit will be in the Georgian banquet on the third floor of the Westin Xiamen Hotel. The hall organized the "24th (Xiamen) LED lighting drive and intelligent lighting technology seminar."
At that time, Shanghai Jingfeng Mingyuan Semiconductor Co., Ltd. will bring their excellent design solutions in the field of LED driving. It is reported that Jingfeng Mingyuan has a general LED lighting product line, smart LED lighting product line and motor drive products. Line, their advantage in LED drive is very obvious.
High conversion efficiency to adapt to complex environments is a technological focus
The main function of the LED driver is to convert the power supply into a specific voltage and current to drive the LED light. The conversion efficiency of the driver is crucial. The external environment is complex and requires the LED driver to adapt to different environments and react at high speed.
At the same time, due to the emergence of emerging applications such as smart lighting, LED luminaires will need to be dimmed and tinted more quickly than ever. These require that the drivers must be able to work stably and efficiently, otherwise all the power not converted into light will be Converted into heat consumption.
High-precision electronic components are the basis for efficient LED drivers
The electrical/optical conversion efficiency of LED lighting systems depends largely on various electronic and optical components such as power management and conversion, drivers, thermal management, sensing and control, LEDs, mixing and scattering, and optical extraction. Therefore, improving the conversion efficiency of the electric/optical power needs to be considered from the most basic electronic components.
Among them, the electrolytic capacitor has a great influence on the LED lamps. It can be used to increase the power factor of the LED driving power supply. It can be applied to the output terminal to eliminate the output ripple of the power supply and release the LED strobe. The VCC used in the driver power supply chip can be used for coupling. The most prominent is the quality of electrolytic capacitors can affect the life of the LED drive power, thus affecting the service life of LED lamps.
