LED lighting market is the key to the power take-off drive

As the LED lighting system is more complicated; across optical, electrical and thermal fields, therefore, conducting large-scale applications, there often does not match the power and reliability of life issues such as inadequate, resulting in LED advantages can not play. In short, LED lighting (LED lights especially) large-scale application of the real bottleneck lies in the drive power.
LED lights is mainly used for outdoor environment, to long withstand wind and rain, thunder and lightning of the harsh environment; in southern China, some time may be as high as the outside temperature 40 ℃ ~ 50 ℃; while in the cold north, part-time outside temperature may be as low as -20 ℃ ~ -30 ℃. Therefore, the power LED street light design and manufacturing technology is even more to pay attention to quality issues.
"Most of the street failures are attributed to a power failure, the design of street facing special challenges, most challenging applications in the traditional power does not exist. The harsh conditions of high ambient temperature (leading to the circuit board temperature exceeds 100 ℃) , coupled with the power and load (LED) of the close proximity, making the standard adapter technology simply can not adds. In addition, Telecom converters used in high ambient temperatures used to deal with high-efficiency method, only part of the application in the street and effective. "Andrew Smith said:" Long life, high temperature power supply require special design and topology, in order to make the power to work in harsh environments. lamp manufacturers often can not accurately determine the applicability of power, the wrong technology selection will eventually lead to premature system failure. "
He pointed out that many of the power supply for outdoor lighting are dependent on large aluminum electrolytic capacitors, but for the harsh environments in the power of the power conversion circuit, the effect of these capacitors is not good. PI cost-effective technology without electrolytic capacitor or other short-lived components (such as optocoupler), thus greatly enhancing the reliability of the external lighting scheme.
Andrew Smith stressed: "PI power control IC designers to help complete the modular design to drive the LED light strings in parallel, to 90% efficiency to work without electrolytic capacitors. In addition, PI also provides a highly integrated, high frequency resonant converter program, through the power in light load efficiency to 92% or more to reduce stress on the power. "
Energy efficient, according to the U.S. Department of Energy (DOE) on December 3, 2009 for the integrated LED light project publication 'Energy Star' final version of the specification, the provisions of the LED driver to be better than 0.7 power factor, and industrial applications are better than 0.9. In addition, LED products currently no comprehensive standard case, LED must meet the mandatory standards, in particular, EMC's GB17743 corresponding IEC6100, current harmonics THD of GB17625.1-2003 corresponds to the IEC61000-3-2: 2001, which requires power to good EMC, PFC / THD.
Drive power LED street light design high threshold
TI Semiconductor Division, Business Development Manager Liu Chao for LED street lamp drive power requirement point out, LED lights from the optical, thermal and electronics components of complex systems, although the LED itself, live longer, but if the LED driver circuit designed properly, such as the selection the low quality of active or passive components, and the overall life of the drive circuit can not be matched with the LED, LED lights will affect the quality and life. Furthermore, LED thermal management and heat dissipation is also very important, once the operating temperature above 100 ℃, LED itself, the reliability will be affected. Of course, LED early failures, defects in the assembly of local and transient phenomenon and other factors, also led to the LED may occasionally fail, if not take appropriate protection measures for diversion, a single LED failure will lead to a whole string of LED is not lit, the overall impact of street lighting the effect.
Furthermore, in the overall LED lighting market, LED lights is the highest power applications requiring multiple power levels and complex topology to meet the power factor correction (PFC), total harmonic distortion (THD), 85 PLUS the efficiency standards and regulations, and multi-string LED current constant demand. Liu Chao believes that to solve the LED street lamp circuit reliability problems, we must drive topology to improve, improve efficiency, reduce component count, while also further reducing costs.
Andrew Smith is recommended that the LED lights drive power with gold / silver / copper grading system. For example, gold-level power in a harsh environment with a long service life, can provide high efficiency (> 90%), and has a high power factor. To meet the Gold standard rating requirements, power supply manufacturers must follow good engineering experience (for example, eliminate the power conversion circuit electrolytic capacitor). Silver and bronze respectively in industrial applications and consumer applications, they meet the unique attributes of these segments.
He said: "The LED power with gold / silver / copper grading standards, the production of street system integrators can easily and safely choose the right technology, without the need to become experts in power as an IC supplier, PI support the LED to a common classification standards and we are working with various LED manufacturers and government agencies, with a view on the need for and content of this initiative to reach a consensus. "
Shenzhen Moso chairman Gu Yongde said that as a large-scale popularization of LED lighting has not yet been applied to the LED driver power demand is relatively small, and there is no uniform national standards, many power supply manufacturers in the design of poor quality, resulting in Power shorter product life, even if in good condition in the application environment, the general life of the power supply manufacturers have less than 10,000 hours; if the ambient temperature of 40 degrees in the summer, there are many manufacturers of power over life, but 4000 hours.
Life and temperature range of key
Gu Yongde that, when put in the design of Moso Power on the temperature specification -40 ℃ -70 ℃, the unique structure of PFC circuit and the internal shield is fully resolved and ensure that in any harsh environment, the power supply can boot normally. Furthermore, through the long period of time gluing techniques, and then deploy the best sealing, cooling of the best potting ratio, so the product can be a complete tight waterproof protection. Moso life of the LED drive power up to 50,000 hours.
Situation for the industry at this stage, Gu Yongde that many lighting manufacturers are mostly complete LED substrate and structural design before going to consider the issue of power, ignoring the supply shock effect on the LED chip, for the lighting of the light attenuation stay hidden. For many small and medium sized power supply manufacturers, they can not have the strength of each batch of small number of different power lamps specially developed, which resulted in LED lighting manufacturers can not find the technical specifications and size are a common phenomenon in the appropriate power supply. Moso Power Supply is the long-term commitment to customer interactions and the general lighting, the different requirements for clients to provide practical applications, and thus to guarantee the quality of lamps, lighting win the trust of customers.
The seven stage Moso Power Supply products are widely used in nearly 1,000 domestic and international customers, including on the ground, really bright, Foxconn, BYD, Jiuzhou Optoelectronics, the history of Ford, Tektronix Tuopu, Bombel, Mason, Green, optoelectronics, photovoltaic Wei Chi, Germany Runda and Foshan country star, and other famous makers.
Moso and Kingsun cooperation and formulate long-term development and the vital interests of both sides of the details of the project development, technology research, technology consulting and services, information exchange, personnel training, etc. to carry out extensive and in-depth comprehensive cooperation, and in the next three to five years, Kingsun LED lighting in existing projects, will be more than 90% Moso custom LED drive power, while new projects will be together for joint development, joint development projects in the above 100% Moso will use high-reliability drive power.
