Zero power LED protection chip developed successfully

The first zero power LED protection chip by asky quantum science and technology limited company independently developed recently in Anhui, Wuhu high tech Industrial Development Zone, and realize the transformation of achievements. This marks the LED lighting industry has been plagued by modular connection formally resolved.

It is understood that this chip is currently LED small lamp series optimal scheme, to maximize the efficiency and reliability of power supply, and the power supply of LED manufacturing industry to achieve a unified standard possible.

The Wuhu hi tech Zone, this protection chip tapeout sample has been used for 6 months in the area of 400 LED road lamps, through on-site inspection, found that the protection chip 54 streetlights play a role, not a street lamp replacement, save the maintenance cost more than 16 yuan.

As we all know, LED is the most efficient and environmentally friendly lighting source. LED lights from a diameter of about 5 mm, combined LED lamp power of 1 watts and. However, these small beads connected way, become a difficult problem in LED lighting industry at present. The full series circuit is the best choice for power efficiency optimization and manufacturing standardization. But the problem is a series circuit, a string of small beads in a burned the entire light Quanmie, thus the whole series circuit in practical application has no use.

In the lighting industry, in order to solve a string of small beads in a burned the entire light Quanmie problem, more than ever to take a packet in parallel, to some small series LED lamp module, a plurality of modules in parallel into the whole lamp. Although this avoids a small lamp burned all ills the light does not shine, but the influence of the whole lamp lighting is larger. Because the parallel circuit makes the current load of other working modules increase, the lamp life is shortened. In addition, modular connection power supply efficiency is low, resulting in low efficiency of LED lamps.

At the same time, the module of different combination of different needs of driving power, the industry has no uniform standards, resulting in power supply design can not standard, for different customers, the power supplier needs to design a different power, so have developed hundreds of electric source to deal with various possible combinations.

Zero power protection chip asky quantum company makes the whole series can be realized, the small lamp in normal working condition, the protection of the chip does not work without current, no power consumption, once a LED lamp burned, immediately replace the bad light to protect the chip conducting current, so as to ensure full series circuit path, not the whole lamp destroy. At the same time through the constant current constant lamp, ensure the life of the lamp.

According to the detection, achieved by the protection chip LED lamp series lighting mode, compared with the traditional industry with parallel solutions, the power efficiency is increased by 2%; at the same time, the whole series circuit of unified driving power supply for the constant current source is 350 Ma, provides a platform for the formation of LED lighting power production standardization.

The first production of 200 thousand pieces of LED protection chip, most of them have been delivered.
