LED street lamp development driving power will no longer be short board

LED lamp with "the direction of energy saving and emission reduction, become the governments attention highlights. The Ministry of science and technology to carry out the "ten city lights" LED lighting demonstration project, Guangdong province puts forward "with thousands of lights" etc.. Electronic components technology network has learned that the local government to support the LED street lamp program, while the quality of high-power LED drive power has become a barrier to hinder the development of high-power LED lighting short board.

Indoor lighting and outdoor lighting conditions are not the same, the technical difficulty is not the same. Power requirements for outdoor lighting:

1 large power, high efficiency, and the amount of lumens per watt light effect, the lamp light effect for more than 68lm/W

2 and the light efficiency is directly related to the efficiency of the power supply, high efficiency, light effect requirements can be attained

3 for LED street lights, tunnel lights LED drive power, 100W power in general, 150W, 200W, 300W, costs accounted for the entire cost of 8% - 10% lamps

4.LED driving power is greater, the greater the difficulty of design and manufacture

LED lights, tunnel lights and high-power LED lighting to promote early, LED driving power supply has many problems, which is not in accordance with the LED street lamp, tunnel lamp environment design, working temperature range is narrow, only -40 degrees Celsius to 70 degrees Celsius; water level is low; the lightning protection level is low; low efficiency that life is not long, only 20 thousand hours, or even 10 thousand hours.

"LED drive power instability is the industry consensus, it gives the LED lighting industry dragged 1--2 back," Moso chairman Gu Yongde said. Poor reliability led to the installation of street lights today, a few days after the power is broken. Street lights, tunnel lights and other outdoor height devices, installation is difficult, more difficult to repair. For street lighting manufacturers, unstable power supply makes maintenance costs more than the purchase price of the product itself.

Saw LED power supply problems, power supply manufacturers seize the opportunity to launch more reliable performance products can win the market. Mao Shuo 06 years in Hangzhou to set up R & D center, hire a rich experience in international power design experts to lead the development of LED street lamp, tunnel lamp power supply. Lasted 2 years, invested in March 2008, the official launch of LED street lights, tunnel lights series power supply, power covers 30W, 50W, 75W, 100W, 150W, 200W, 300W. In solving the reliability and life expectancy, the experience is worth learning.

How to ensure the reliability and life?

The reliability of "mosopower power, through the development of design technology to ensure raw materials accounted for 60%, accounting for 30%, accounting for 10% of the production process. Mao Shuo power from the beginning of the use of U.S. military power technology to ensure the reliability of the design, Mao Shuo power chairman Gu Yongde said. Mao power source of raw materials from the vast majority of imports, IC comes from Infineon Germany original, the capacitor is all military grade Japanese capacitors, raw materials, only the shell, lead, PCB three is from local enterprises.

Mosopower power negative rate of less than about 5, the efficiency reached 95%, small temperature rise, life more than 50 thousand hours, with 5 years, waterproof level Ip68 standard, lightning protection level reached more than 4KV.

How to delivery?

Because most of the raw materials imported, so the preparation of raw materials in the very great degree about the length of delivery. The original order cycle is 8 weeks, and now in order to solve the problem of long delivery, Mao Shuo prepared a set of materials in advance, nearly 25 million yuan in advance, with the second half of the booming demand for LED street lamps.
