The development of drive power LED lights will no longer be short board

LED lights meet the "energy saving" principle, become the concern of governments around the highlights. Ministry of Science and TDA7269A datasheet and carry out the "city of ten thousand ten" LED lighting demonstration project in Guangdong Province that "ten thousand miles" scheme and TDA7269A price and so on. Electronic Components Technology Network has learned that the Governments strong support for the LED lights around the scheme, the quality of high-power LED drive power, but off high-power LED lighting that hinders the development of the short board.

Indoor lighting and TDA7269A suppliers and outdoor lighting conditions of use very different technical difficulty is not the same. Outdoor lighting power requirements:

1. Power, high efficiency requirements, and have the entire amount of lumens per watt efficiency requirements for lighting, street lighting efficiency requirements to reach the entire 68lm / W or more

2. And the lamp light efficiency is directly related to power efficiency, power efficiency, the entire lighting efficiency requirements be possible to achieve

3. For LED street lamps, tunnel lamps LED drive power, the power is usually in 100W, 150W, 200W, 300W, lamp cost of the total cost of 8% - 10%

4.LED drive power power the greater the difficulty of designing and manufacturing the greater

LED lights, tunnel lights, LED lighting to promote the early high-power, LED drive power, there are many problems, mainly not in accordance with LED lights, tunnel lights harsh environment in which to design, narrow operating temperature range, only -40 ℃ - -70 ℃; water level is low; mine low-grade; efficiency is low, life is not long enough, only 2 million hours, or even 1 million hours.

"LED drive power instability is the industry consensus, and drag it to LED lighting industry by 1 - 2 years of hind legs," chairman Gu Yongde Moso Power said. Poor reliability led to todays installation of street lights, no power on the bad days. Lights, tunnel lights and other outdoor equipment height, installation is difficult and maintenance more difficult. For manufacturers in terms of street lights, unstable power supply makes the maintenance costs exceed the purchase price of the product itself. High Power LED drive power

see the problem, power supply manufacturers to seize the opportunity to launch the product more reliable can win the market. MoSo set up 06 R & D center in Hangzhou, the power to hire experienced design specialists to take the lead in international R & D LED lights, tunnel lights drive power. Lasted 2 years, invested more than 2,500 million, in March 2008 launched LED lights, tunnel lights power supply, power covers 30W, 50W, 75W, 100W, 150W, 200W, 300W. Terms of reliability and life in the settlement, the experience is worth learning MoSo reference.

How to ensure the reliability and life?

"MoSo reliability of power supply, through the development of design techniques to ensure that 60%, 30% of raw materials, production processes accounted for 10%. MoSo power from the outset by the United States military power technology to ensure the reliability of the design" , chairman Gu Yongde Moso Power said. MoSo most from imported raw materials supply, IC from Infineon German original, capacitors are all Japanese military grade capacitors, only the shell of raw materials, lead, PCB from three local companies.

MoSo extreme power of non-performing rate of less than 5, the efficiency is 95%, temperature rise is small, life over 50,000 hours, 5-year warranty, water level reaches Ip68 standard 4KV rating achieved more than mine.

How to ensure the delivery? Most of the raw materials imported from

, so the preparation of raw materials around a large extent, the length of delivery. The original ordering cycle is 8 weeks, and now to solve the problem of long delivery times, MoSo 20 million pre-prepared material, advance nearly 25 million yuan, with the second half of the booming demand for LED lights.
