[Text / Long Zonghui] LED lighting this year's rapid development has made the industry see a turn. However, the problems of low reliability, poor maintenance and replacement, and poor performance indicators of LED lighting systems are still technical shortcomings that restrict the development of the industry.
The biggest advantage of LED lighting compared to traditional lighting is energy saving, but the general LED lamp bead can not directly connect to high voltage, so the power supply must be AC-DC converted, which greatly causes the power consumption loss, and directly accesses the AC. It is prone to many technical problems such as stroboscopic and EMI.
On November 26th, the 2013 Hi-Tech LEDCTO Conference held in conjunction with the 2013 Gaogong LED Lighting Exhibition will be held at 13:30 pm at Guangzhou Poly World Trade Center. The D meeting room of the museum is held.
At that time, Huashunxiang, the director of Zhongheng Paiwei Sales Department, will release the company's new generation of HVDC-powered LED lighting system. It will directly access the exchange and consume less energy. After thoroughly solving the above technical problems, cost control can also be done. better.
Hua Shunxiang revealed that the rectifier module at the core of the above HVDC power supply system can carry three-phase, 323-475VAC, the output current can be 0-22A, the output voltage range can be 200-400Vdc, the highest efficiency is greater than 95%, and the power factor can be More than 0.99, THDI <5%, maximum output power 6000W. At the same time, the HVDC core component monitoring can be directly operated with the touch screen, supports the Linux operating system, and has powerful event management functions.
HVDC DC busbars are all powered by N+X redundancy. Even if there is a module failure, it will not affect the overall power supply, thus improving the reliability of the system power supply. At the same time, only the DC-DC constant current drive is used on the lamp, and the traditional drive power supply Compared with the first-level AC-DC link, the constant current drive on the luminaire has high reliability and long life.
Compared with traditional power efficiency, HVDC monitoring is used to implement the sleep function of the N+X redundancy module, which ensures high efficiency under various load conditions. In addition, maintenance is also very convenient, HVDC power supply system has been placed on the road, no need to climb the car for repair. The HVDC power supply module has a hot plug hot swap function that can replace the faulty module in case of continuous power.
The biggest feature of this HVDC is its low cost. At present, the power supply can reach a life of more than 20,000 hours. The average price is 2.5-3 yuan/W, and the HVDC power supply can greatly reduce the cost. When the power supply reaches 15KW or above, 1.5-2 yuan/W can be realized. When the number of lamps is relatively large, the use of HVDC power supply can also reduce the cost of the entire system.
Hua Shunxiang said that the new generation of HVDC-powered LED lighting system has been tested for stability and cost performance.
