Angbao Electronics Libo: Simplified, BOM destocking will become the driver IC next
With the changes in the competition and demand situation in the downstream terminal market of the LED industry, the driving IC industry is also facing challenges and opportunities that are different from the past. The maturity and extension of technology has spawned a more active industry ecosystem. In this round of competition, the innovation of enterprises in products and markets is even more important. At this year's Guangzhou International Lighting Exhibition, Angbao Electronics exhibited a new generation of dimming/non-dimming products, and made many innovations in the improvement of product technology and solutions. Compared with the industry, its attempts in intelligent lighting and IoT applications are also worthy of attention. Recently, Aladdin News Center reporter interviewed Lebo, Vice President of Electronic Marketing Department of Angbao, to explore the optimization of driver ICs Process, develop more innovative and cost-effective products on the Angbao mode layout. De-strobe thyristor dimming perfect presentation When using a mobile phone to take a close-up view of the LED lighting, we will find that the LED light will continue to flash at a high frequency, rather than flickering, if not conscious It may not be easy to find out. Angbao Electronics made a lot of efforts on the strobe and achieved more breakthroughs. This year's Guangya Exhibition, Angbao Electronics also introduced a number of solutions to power frequency strobe, such as OB3670/OB3672 high power high PF no stroboscopic scheme, OB562x alternative RC buffer strobeless scheme. Even the most difficult to avoid stroboscopic thyristor dimming solution, Angbao Electronics also introduced OB3663+OB3671 and OB3665+OB3671 thyristor dimming stroboscopic scheme. On the strobo-free scheme, Angbao Electronics should have the most A complete launch program. During the exhibition, it was pointed out that some of the products of Angbao Electronics (the 60-inch lanterns on display) had stroboscopic problems. Li Bo clarified by the Aladdin News Center that this was a misunderstanding. Li Bo said that the real source of strobe should be the metal halide lamp for general lighting purposes at the Anbao booth. The photo of a registration form taken under the metal halide light line of the on-site booth lighting also clearly reflects the power frequency strobe generated by the metal halide lamp. Therefore, the root cause of the video strobe is not the Angbao's The lighting scheme is just a misunderstanding of the eyes in the natural situation. Actively deploying intelligent lighting Because of the future development of smart lighting, LED power supply and driver IC companies have already begun to get involved. Domestic IC companies, including Angbo Electronics, Mingwei Electronics, and Dialog, have placed the market in order to gain a place in future technological innovations, making their products more compatible with intelligent lighting control systems. Li Bo told the Aladdin News Center that the current Anbao electronic product line covers chargers, adapters, TVs, Netcom power supplies, LED lighting, etc., and has been incorporated into the Internet of Things and smart home concepts in future plans. It will provide a one-stop solution from the underlying power drive solution, wireless communication hardware solution to firmware software and system applications. Customers can choose the power solution, wireless communication solution and software of Angbao Electronics according to their own needs. A series of dimmable drive solutions OB3333/OB3333B and OB3600/OB3602/OB3603 from Ong Electronics directly support MCU PWM dimming, simplify system design, and provide standby power supply to reduce system BOM and volume. Based on independent research and development, Angbao introduced On-Bright LinkTM wireless interconnect technology, which not only supports intelligent lighting network systems, but also can be easily extended to smart home and IoT applications. This low system cost and complete hardware and software solution can better support customer smart lighting and smart home applications, and more quickly turn the vision of smart lighting into actual products, Li Bo said. The difference is that Angbao Electronics seems to have spared no effort in the construction of software. Li Bo believes that software is an integrated creative idea based on hardware, which is more personalized and more flexible. The overall solution from hardware to software makes it easier to solve the problem of insufficient customer R&D resources and tight product launch time, and provide more support for customers' products to move from the low-cost competitive Red Sea market to the Blue Ocean market. With the birth of intelligent lighting, it also promoted the arrival of the Internet of Things era. In the future, smart lighting will accelerate to expand into the network field, software field, and mobile phone field (tablet system). At the same time, with the deepening of the concept of intelligent lighting, the speed of lighting popularization is accelerated and the cost is further reduced. In the future, intelligent lighting will be the mainstream of lighting, and also the trend and direction of LED lighting driving technology challenges. Simplification will become the new direction of driving ICs Currently in the field of LED lighting, especially general lighting, many LED products are still driven by switch mode power supply. With the continuous improvement of the driving power supply scheme, the driving volume is continuously reduced and compatible with TRIAC dimming, which can prolong the life of the bulb and reduce the cost, and is expected to become a new direction of LED driving in the future. LED lighting drives have evolved from the original bulky and bulky isolation type to the current non-isolated type, with smaller size and higher efficiency. Li Bo said that with the smaller and smaller size of the bulbs on the market, the driver IC will gradually develop from the current mainstream non-isolated type to the future integration, and the driver IC will be more streamlined and the BOM will reduce inventory. The direction of development. The OB562x series driver IC solution introduced by Angbao can form a driving power supply with a minimum of 6 parts. The volume is very small, and it is almost the same as the index finger of an index finger. It can even be placed in the lamp holder of the E14 filament lamp. In the past, the LED filament lamp resistance and capacitance scheme has a narrow voltage input range. Li Bo said that such driver IC solutions have the advantages of low cost, convenient installation, and simple intelligent dimming. Therefore, dimming and streamlining the BOM direction of the system will definitely become an important route for the LED industry to develop in the driving field. Green Driver IC Design Innovation Undoubtedly, thanks to the green concept layout, Angbao Electronics is stepping faster on the road to becoming a leading IC design company in China. Reducing product energy consumption has always been the goal pursued by both manufacturers and consumers. With the advent of the era of cost-effectiveness, low energy consumption provides a greater advantage for improving product competitiveness, and innovation and breakthrough in driving IC design is the way out. Angbao Electronics is the industry leader in reducing power consumption based on the Green EngineTM technology platform. For example, its OB3333 high PF value dimming solution not only provides dimming full-range constant current drive but also provides power to the dimming control mode. The group does not require a separate power supply, and the standby power consumption can be as low as 0.3W or less, which is much smaller than the 0.5W standby power consumption requirement of the EU. Li Bo said that maximizing the customer system power solution can achieve mutual benefit and win-win for both parties. Angbao Electronics will adhere to the most stringent energy-saving standards, and all current chips can meet all energy-saving standards. The next stage of competition in the LED industry is the price-performance war, and the continuous improvement of cost-effectiveness has become the goal of the entire LED industry chain. As the price of LED terminal products continues to decline, the proportion of LED driver ICs in the overall cost of lighting fixtures has become more and more prominent, driving chip manufacturers to compete to optimize the driving scheme to meet the low-cost requirements of related manufacturers. Streamlined, green, and efficient products will certainly be more popular, and the overall system of LED driver ICs in the future should be developed in this direction. Li Bo believes.
