Item specifice

Our LED lights adopt the AC directly drive solution and three-phase power directly drive patented technology which are the pioneers in LED field all over the world.

The LED can adapt to AC160-380V electric supply. The AC solution discards the external LED power driver which seriously affects the service life of LED light, so the service life and stability of LED were greatly improved. (The service life of Yushan AC drive solution is more than 100,000 hours)

Our three-phase power directly drive patented technology is the global unique successful application in LED street light. This technology won the award of the 2014 Geneva International Exhibition of Inventions.   

The world leading AC directly drive technology

We possess the world leading AC directly drive technology and globally unique three-phase power directly drive patented technology which won the award of the 2014 Geneva International Exhibition of Inventions.

As the leader of advanced lighting technology in China, we will guide the new trend of no driver LED in the world.

Independent researched and developmental core chips

TF11 is a chip which is specially designed for the output of voltage change of the AC electric supply in LED lighting. It can adjust the quantity of loaded LED to realize the efficiency and power factor LED driving solution. 

G13 is the Integrated circuit which is special for the control of over current and over voltage. According to the change of voltage, G13 could ensure the stability of LED, improve the reliability and durability of LED.  

The TF11&G13 AC directly drive integrated circuit totally replaces the traditional LED driver, it realizes a reliable and high efficiency LED AC drive system.   

Perfectly solves the biggest disadvantage of LED

Super long service life, constant stability

Globally unique three-phase power AC directly drive technology.

The creative three-phase power AC directly drive technology ensures that the street lights could access the AC160—380V electric supply directly. This could reduce the line reconstruction of the traditional electric transmission line, it will save a large cost in the street light projects.

The highest luminous efficacy, low luminous attenuation 

Choose high quality luminous resources that the light efficacy is more than 170LM/W.

The luminous efficacy of our street lights is more than 50% comparing with general street lights.

We provide the most energy-efficient street lights in the world to our clients.

The LED chips are encapsulated through multicrystal method so that the rate of dead lamp declines to a lower level.

The luminous attenuation of the whole light is less than 3%.The total luminous attenuation in 8 years is less than 20%.

Particular optical system

Utilizing the ZAG lens technology developed by USTC, the gap between the lens of light distribution and luminous source was filled by the colloid that ensure there is no air in the gap. This technology could realize the transmittance without light loss. Comparing with general products, the light efficacy of our LED is increased by 7%, the transmissivity reaches up to 99.8%. 

According to the statistical data of LED errors, the percentage of the faults caused by circuit structure is 20%.

The percent of luminous source fault is 10%,

The percentage of the faults caused by driving power is 70%.

Thus it can be seen that the LED driver is the most important factor to decide the quality of LED lights.

Precision production, modularized design

Modularized design (encapsulated by 30-45W high luminous efficiency module).The design needn’t the maintenance by tools, the replacement is easy like replacing a bulb. There is a stepless dimming interface on the module which is available for the smart lighting service.
