The rapid development and maturity of LED lighting technology, the monopoly of traditional lighting sales and the replacement of LED energy-saving lamps in the "long-distance running" due to the rapid decline in price difference, the price of lighting fixtures represented by LED bulbs and LED fluorescent lamps is rapid "Shrinking" has made the cost of the civilian LED lighting market almost equal to the price of high-end energy-saving lamps under the concern of consumers.
At present, in the general LED lighting market, there are non-isolated designs and isolated driving power sources on the LED driver. Non-isolated designs are limited to dual-insulation products, such as bulb replacements, built-in fluorescent lamps, where the LEDs and drive are sealed in non-conductive plastic, glass or ceramic, so the end user does not have any risk of electric shock. The brand of Delip Optoelectronics Co., Ltd. - see the power supply series of the power supply is 1-30W, using low current and high voltage output design, divided into normal version and certified version, a total of 14 drive products, ready for sample.
Highly insulating housing will play an important role in future LED general lighting
See the designer of my power supply that the future of indoor lighting will be more and more high-insulation housing. The physical structure design determines whether the drive is isolated or non-isolated. As a product that can be safely used by end users, the reliability of insulation and isolation must be considered.
As a complete product, the parts of the product surface that are accessible to the user must be isolated and not subject to electric shock. From the overall design of the product, isolation is inevitable, the only difference is the location of the isolation. Delip has always believed that plastics, ceramics or glass, which are low-cost, easy-to-scale and easy to transport, will be the mainstream of the future application of high-insulation structure for lamp housings.
For example, the early LED fluorescent lamps used a full plastic tube, a non-isolated power supply and a φ5 straw hat tube LED. Light attenuation or short life due to heat dissipation problems. Now LED light source has improved lumens and power density, using fewer light sources, and lowering the brightness requirements of traditional lighting fixtures. At present, Philips, Foshan Benbang, Shenzhen, Nengeng Optoelectronics, etc. have introduced LED fluorescent tubes represented by plastic pipes and glass tubes.
LED driver based on non-isolated design will be the mainstream of bulb and fluorescent lamp applications
The ability to manufacture cost-effective and reliable products has always been the direction of the lamp manufacturer's unremitting efforts. As the heart of the lamp, the LED driver has always occupied a large proportion in the overall cost of the entire lamp product.
A few years ago. Because of the light efficiency and reliability relationship of LED light sources, high-power light sources have always played a leading role in market circulation, which has led to more high-current and low-voltage output isolated LED drivers in LED driver design.
In the future, in the comparison of the comprehensive technology maturity and cost-effectiveness of isolated, non-isolated LED drivers and linear drives, non-isolated LED drivers are most likely to be used in large quantities in the general lighting market in the next two years. Non-isolated LED drivers perform well in terms of internal space size, less device reliability, and high conversion efficiency and low heat generation. Objectively speaking, the non-isolated power supply has a poor ability to suppress the lightning surge voltage. As long as the lightning surge is avoided indoors, the impact can be avoided.
The update speed of the power supply technology is updated in three months, and the speed of the replacement of the six months is seen. The product design positioning of the power supply exceeds the resistance and voltage reduction in the reliability, and exceeds the isolated LED driving power in the overall cost. It is firmly believed that the future of indoor lighting will be increasingly made using a highly insulating outer casing. This kind of constant current switching power supply has achieved the cost of directly resisting the buck circuit. In the application example of the power supply, the typical conversion efficiency of the 3-5W power at full load can be up to 90%, but it should be noted that high insulation housing such as plastic parts, ceramics or glass is needed for structural applications to avoid safety. problem.
Low overall cost will be a big advantage for non-isolated LED drivers
Typically, manufacturers of LED luminaires analyze luminaires in many ways, such as cost and manufacturing processes, efficiency and volume, insulation reliability, and safety specifications. According to the general theory, the less reliable the components in the electronic circuit, the higher the reliability.
Non-isolated circuits have fewer components than isolated circuits. Non-isolated LED drivers are more efficient and cost-effective than isolated LED drivers. At the same time, due to the medium power source (3014, 2835, 4014, 5730, low current high The voltage output of COB, etc.) is improved in light efficiency and technical reliability is mature. Low-cost integrated solutions (including LED light sources, heat sinks and LED drivers) are always an important driver for consumers to decide to purchase and popularize LED general lighting products.
For example, many companies are currently seeking to reduce the cost of LED fluorescent tubes indirectly. The 2835 package series has gradually become one of the main light sources for LED fluorescent tubes. 2835 is a 0.2W series product, so the number of LED fluorescent tubes used under the same power will be reduced by more than half, no matter the manufacturing cost and light source cost reduction is obvious; from 2013, LED fluorescent tubes will form a medium and high power series LED fluorescent lamps. The LED fluorescent tube market is mainly supported by series of light sources such as 3528, 3020 and 3014.
After 4 months of verification and testing, the “See You†cost-effective driver of Delip Optoelectronics has released an ultra-cost-effective driver that can be used on bulbs and fluorescent lamps with a power range of 1-30W. According to the subdivision of the applicable variety of bulbs 1-18W ordinary and certified models, fluorescent lamp 6-20W series, ceiling lamp 12-30W series. In summary, with the adoption and guidance of high-insulation materials, non-isolated general lighting drive solutions are the general trend.
