Power to become a weakness in LED engineering lighting

A focus of global attention and significant investment: LED industry.

LED driver development power through the whole industry chain of LED can be compared to maintain the development of the LED industry blood, lack of LED power supply, the development of the middle and lower reaches of the short circuit, slow, unable to realize high speed leap, therefore, in the China LED industry chain gradually mature today, mastered the advanced and reliable LED drive, will quickly seize the market, to quickly realize the industrialization of LED.

Fang Fang, general manager of the big powers, said Fang Fang, due to the problem of power to eat a lot of losses, but also spent a lot of time and cost, the power problem has become a weakness in LED engineering lighting.

At the same time, in the process of visiting the Shenzhen quantum photoelectric Liu Zhen, we are also deeply aware of the importance of power problems. Liu told us, "we have no problem of chip LED lamp power supply, but early damage, although the LED lamp itself is good, but the show in front of customers is not your lamp, the lamp is broken, can not be used. Therefore, the power is still a confusing problem. "

Dr. Hongkong micro Bo visited our division, but also give us more thinking:

Power problems, also appeared in the United States and the United States, Jiuzhou, LIAN, national star, Heshan silver rain and many other large enterprises. Many companies set up a special power supply R & D team, not only caused huge investment, but also greatly extended the application of LED industry cycle, and brought a variety of subsequent problems caused because the power is not reliable.

Problems to be solved:

LED lamp ESD protection 1 package in the link and open circuit protection problem;

Developed with electrostatic protection device, so that the LED can prevent static electricity, also avoid one damage (open circuit) caused by the whole lamp string does not light the situation.

2 high voltage AC input provides constant current source;

Provides constant current source driver for the best LED, keep it in the best working condition; provide a reliable basis for the popularization and application of LED.

The power supply scheme 3 engineering application;

Due to differences in weather difference, around the voltage of the LED work environment, design and application in practical engineering of various special specifications and requirements.

The backlight power supply scheme of LED 4.LCD display;

The driver chip high efficiency and small volume, to replace CCFL LED as backlight quickly provide the perfect display space.

5 car can go up or down a constant current source driver;

One of the key LED stationed in the automotive sector is the voltage parts used are inconsistent, replaced by the market to the single or single drop type constant current source will be to rise and drop the chip of self regulation, is a new type of constant current source.

The constant current source 6 special industrial applications LED.

In some high targets, such as ships and military fields very harsh on the product requirements, some voltage up to 500V, the LED in a huge difficulty and challenge to the power supply, constant current source, we can have a go.

At the same time, application should be extended LED: such as shipbuilding industry, military field, automotive field, LCD liquid crystal display.
