In view of the large number of light-emitting diode ( LED ) lighting fixture factories, mostly for small and medium-sized enterprises, coupled with the maturity of system design, they face many technical challenges, On Semiconductor, STMicroelectronics (ST) Texas Instruments (TI) competes with National Semiconductor (NS) and other chip vendors to attract customers through cost-effective reference designs that accelerate time-to-market.
Lin Zhiyan, technical marketing manager of ON Semiconductor and Consumer Electronics, said that only by actually understanding the specifications required by customers can we design a reference design that meets customer expectations.
Lin Zhiyan said that most LED lighting manufacturers are more dependent on component suppliers due to insufficient power supply and system integration capabilities. If the chip manufacturer can provide a reference design for the needs of different lamps, it will help customers shorten the product development time and produce cost-effective LED lamps. At this stage, the company has been able to provide reference designs for four to six bulbs, such as MR16 and PAR30, and will introduce reference designs for ten to sixteen bulbs in the future.
Not only Amsene, STMicroelectronics, Texas Instruments, National Semiconductor and other LED lighting power supply and driver chip vendors have also published a variety of LED bulb reference designs, showing the semiconductor industry heroes see the same. Lin Zhiyan stressed that although many chip suppliers have introduced a variety of LED lighting reference designs, whether they can meet customer requirements for high profits, cost-effective, electromagnetic interference (EMI), and the actual goal of accelerating the time to market.
Following the acquisition of SANYO Semiconductor in early 2011, Anson has obtained a non-isolated LED driver chip product line and technology. Lin Zhiyan pointed out that in the future, ON Semiconductor's isolated and non-isolated LED driver chip product line will be more Complete to meet the needs of customers in different application areas.
In view of the development trend of LED lighting isolated and non-isolated driver chips, Lin Zhiyan analyzed that LED lighting systems use metal heat dissipation design, so they must be separated by mechanism or electrical appliances; once the ceramic heat dissipation system architecture is changed, especially 5-7 watts. Low power, limited by size and cost, will be a trend with non-isolated solutions, and in the future, non-isolated boost, buck and hybrid architectures will be available in the market.
Compared with the LED backlight TV market, LED lighting is highly customized. Lin Zhiyan believes that the development of LED TV is more mature than LED lighting, so the industry has gradually developed a unified standard, and LED lighting The proportion of manufacturing is high, and semiconductor companies must have more flexibility in product design and supply to meet market demand.

Electronic Assembly, it also could call electronic product assembly or finished product assembly or box build.
After the Electronic PCB Assembly done, and the PCBA boards tested well, then we can start the electronic assembly to fit the PCBA boards inside the product shells. For the product shell, it could be provided by customers or we can manufacture it with the design files.
If provided by customers, the customers need to provide a finished product or an assembly guide file to lead us.
If we manufacture it, the customers need to provide the design file and a finished product or an assembly guide file.
Service process:
1. Sample/Drawing
Provide your design files, IGS ,STP or DWG files are welcome.
