Successful development of ultra-low-power protection chip will reduce the cost of LED lamps

The reporter learned from the Wuhu High-tech Zone Management Committee on August 22 that a led protection chip with a power consumption of only 0.1 microwatt has recently been successfully developed in Wuhu, and has obtained national utility model patents. The ultra-low-power protection chip was independently developed by Anhui Quantian Quantum Co., Ltd. and enjoys the reputation of the world's first zero-power LED protection chip. It solves the modular connection method that has been plaguing the LED lighting industry and greatly reduces the cost of LED lighting. LED lighting pave the way into ordinary families.

As an efficient, environmentally friendly lighting source, LED lamps are generally composed of LED lamps with a diameter of about 5 mm and a power of 1 watt. However, the connection of small lamps has always hindered the popularity of LED lamps. LED lamps on the current market, either full series or grouped parallel lamp beads, both have drawbacks: a small lamp beads burned in series after the entire lamp is completely destroyed; grouped in parallel although avoiding a lamp beads burned the whole lamp is not lit The situation occurs, but it greatly increases the current load of the luminaire-related modules and shortens the lifetime of the LED lamps. What is even more daunting is that the different combinations of parallel connections require different drive power supplies. The combination of complex drive power makes the price of LED lamps high. The protection chip that Tian Quanquan designed was “very clever”. Once a lamp is burned, the protection chip immediately replaces the bad lamp to turn on the current, allowing the full series circuit to access the circuit.

The LED protection chip not only protects the entire lamp but also keeps the current through the lamp bulb constant, extending the lamp life. Asked the person in charge of Tianquan Company, for example, the service life of traditional LED lamps and low-end lamp beads ranges from six months to one year, and that of high-end lamps only lasts two years. After using ultra-low-power protection chips, even if the installation is low End-beads LED lamp life is also up to five years. According to inspection, the LED lamp bead full-series lighting method implemented by the protection chip, compared with the current industry in the traditional module parallel solution, the power efficiency increased by 2%; at the same time, the unified series of circuit power supply requirements for the unified 350 mA The constant current source provides a platform for the standardization of LED lighting power supply production and manufacturing. At present, the first batch of 200,000 pieces of protection chips that Quanqin Co. Ltd. has produced have been delivered to relevant units.
