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
The traditional drivers of LED are easy to damage, which becomes the biggest technical defect which decreases the service life of LED. At the same time, the high manufacturing cost is also the main factor which increases the cost of LED.
The no driver design of LED radically reduces the damage rate of LED, greatly improves the reliability of lightings.
Super long service life, constant stability
Our LED adopts AC directly drive power solution ,it 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 that are more than 10,000 hours (more than 8 years), twice as long as that of general street lights. Our company could provide the longest warranty of LED street lights in the market.
Remove the transformer, MOSDET, electrolytic capacitor and other components which restrict the life of the driver. So the service life of AC directly drive circuit can reach semi-permanent state that surpasses the LED luminous source. At the same time, the volume of AC chipset is much smaller than traditional driver.
Have over current, over voltage, reverse connection protections, which ensures the service life and stability of products.
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.

- Q: In the solar street lighting system, who is the LED driver connected to? How to choose the LED driver power?
- This will save up the power supply in the lamp holder trouble, LED lamp cap damage rate is the highest power, previously in the lamp holder, and now generally will be placed below.
- Q: How to judge the light type of LED street lamp?
- It will be tested by a large distributed photometric tester,
- Q: Do 150wled street lights use much?
- The problem of heat dissipation of domestic high-power LED street lamp has not been completely solved, and the cost of follow-up maintenance will inevitably increase.
- Q: The same brand of chips, how to judge the quality of LED lights?
- Pay attention to the LED chips used in LED street lights. LED chip is the core part of LED street lamp, and the quality of LED chip affects the service life, brightness, light color of LED street lamp, etc.. The general import LED chip slightly better quality (such as Puri and CREE) as a municipal engineering, personal recommendations in addition to the two kinds of chips are not other, Liaoyuan century products outdoor Puri CREE, indoor use of wafer,
- Q: Can you install LED street lights in your own yard?
- Yes, of course. The LED street lamp is the same as the street lights you see outside. You can install LED street lights. Or I told you to install solar LED street lights. I was in Jiangsu Simeier solar street lamp factory Wang Feihui. Their own courtyard, such as Anhui solar street lights, Guizhou solar street lights, Guangxi Liuzhou solar street lights, 90% of the country can be in accordance with the solar street lamps. No electricity. You can think about it. Anyway, LED street lights can be installed yard, according to your courtyard where much of the pole to do a few meters, it is.
- Q: What is the heat dissipation principle of a LED street lamp?
- Mainly include: natural convection heat dissipation, fan cooling, heat pipes and loop heat pipes, heat dissipation, etc.. The fan is forced to heat, the system is complex, the reliability is low, and the heat pipe and the loop heat pipe have a high cost of heat dissipation.
- Q: Do ballast ballasts need to be used for starting the LED street lamp?
- The driver for the LED street lamp is isolated constant current power, high power factor and high efficiency, so capacitor compensation is generally not requiredIf there is an insider, cut corners and use aluminum as a power source, that's another story
- Q: LED street lights generally use how many W, how much density is more appropriate?
- Most of the 1W with LED, taking into account the heat and street size, the general LED spacing about 30MM is more appropriate
- Q: How is the minimum illuminance of LED street lights Emin obtained? How to calculate?
- Minimum illumination Emin, if you go to calculate or use lighting software (DIALux) simulation, you can get the minimum illumination Emin, how to simulate this? This is not clear
- Q: LED street lights installed on both sides of the road, horizontal installation and angle installation (0~30 degrees), natural convection heat dissipation, that good heat dissipation.
- There is a good angle to install, hot and cold air quality is heavy, there is an angle easier to form air convection
