Intelligent and energy storage integrated led street light lamp aluminium 5 years warranty

In fact, for street lamps, higher efficiency and longer life are indispensable to reduce costs.
The switching power supply designed for LED lights must also be efficient and durable to ensure that it has the same maintenance-free life as LED lights.
Resonant converters are one of the most popular power topologies here because their performance leads to higher power efficiency and reduced EMI than previous power topologies.
Soft switching is an important feature of resonant converter.
However, the use of parasitic diodes (bodydiode) in resonant converters sometimes leads to system failure.
The charge stored in the parasitic diode must be completely removed to avoid large current and voltage surges, including high dv/dt and high di/dt in the topology.
Therefore, the key parameters of the power MOSFET, such as Qrr and reverse recovery dv/dt, will directly affect the dynamic performance of the resonant converter.

Zhejiang Coursertech Optoelectronics Co.,Ltd.,established in 1987,is a stock enterprise that professionally manufactures
illumination lights.The lights with "COURSER"brand have already enjoyed a certain reputation in both domestic and
international market.Coursertech has passed ISO 9001:2008,SGS,CCC,RoHS certificates etc.,meanwhile got 55 national patents.

Relying on the conception of "be Vigilant in Peace Time,Science and Technology Innovation",our company cooperates
with Beijing Kedian Microwave Electronic Co.,Ltd.,which belongs to the Institute of Electronic of Chinese Academy of
Sciences,we together built Zhejiang Coursertech Optoelectronics Co.,Ltd.Depending on the technical strength of Chinese
Academy of Sciences,with advanced production equipments and high-quality imported electrical components,we
successfully develop and manufacture two series products:
1.Solar Photovoltaic Power Station,Solar LED street lights,Solar Landscape lights,Solar garden lights,Solar Lawn lights etc,
2.Intergrated Intelligent LED Power Supply,LED street lights,LED tunnel lights,LED Floodlights,LED Highbay lights,LED Commerical,
Home lightings rtc.Meanwhile,we optimize the combination of solar energy and LED lighting perfectly.
Over the last few years' practice,it proves that solar street lights manufactured by Coursertech has been able to reach 365days normal
lighting out of climate impact,light decline rate of LED lightings controlled within 8% after using 30000hours,conversion efficiency reach
more than 92%,power factor reach 0.97.LED street light refector designed by Coursertech,could increase efficiency 30% higher,has got national
invention patent!

Coursertech will keep on "Comprting First-Class Technology,Creating First-Class Quality",endeavor in building first brand of Chinese health
environmental protection and energy-saving applying industry.Coursertech is also in luminous environment design,engineering installation,gather
developing,manufacturing,as well as serving as one unity.We focus on products quality all the time,consider technology development as motivity,
trying to make COUSER bigger and stronger!
