AC directly drive LED Street light  high  Luminous Efficiency no driver

AC directly drive LED Street light  high  Luminous Efficiency no driver


AC directly drive LED Street light  high  Luminous Efficiency no driver

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, Yushan 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 Yushan LED radically reduces the damage rate of LED, greatly improves the reliability of lightings.

 

Super long service life, constant stability

Yushan 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 AC160380V 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%.

      

The lowest color temperature in this field. Exclusive Street light with warm white light

Yushan Photoelectric is the first manufacturer in China who supplies the LED street lights under 3000K color temperature. The color temperature of street lights covers 2800-6500K, but the light efficacy is more than 140LM/W, it is a world leading level.

 

The low color temperature light could excellently penetrate the rain and fog, so the LED light could perfectly replace the the high pressure sodium lamps.

 

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.

 

Superior heat sinking, core advantage

 

Patented fin type heat sinking technology which follows hydromechanics theory: the temperature rises less than 20 Celsius. Adopt the heat sink structure with air flue which is wider at the top and narrower at the bottom, this structure forms the space for air flow that pulls hot-air out of the bottom. It accelerates the flow velocity and cools the lights more rapidly that keeps the LED luminous source in the most comfortable situation.   

 

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.  

Energy saving pioneers, environment friendly

Save much more 70% electric energy than traditional high pressure sodium lamps, save much more 50% electric energy than general LED lights.

  

The LED without driver reduces the reactive power loss (the driver consumption near 12% of total).So the power is more sufficient and the luminous efficiency is higher.

 

Use a power of 120W Yushan AC LED Street light to replace the high pressure sodium lamps which uses 400W or general LED street light which uses 185W.

Compare with high pressure sodium lamps, Yushan LED street light could save 1312 kilowatt hours per year.

Compare with general LED Street lights, Yushan LED street light could save 260 kilowatt hours per year.

Q:What's the reason that the LED street lights flash out?
In addition, there may be LED damage. Among them, LED short-circuit, resulting in the number of LED series to reduce, LED voltage at both ends of low, low beyond the power output voltage range, at this time the power will protect, there will be flash phenomenon.
Q:What role does the light controller and driver play in the LED street light component?
At present, the pulse drive chip is powered by a high frequency pulse generator output interface to the LED lamp. Because the pulse signal frequency is very high, so the human eye can not feel the LED strobe, so this method meets the visual needs, and on the one hand, effectively save the power output. Also, the frequency of this type of chip can generally be controlled by an external interface. However, the current frequency of this type of chip is generally in the range of 100KHz~500KHz. So the current drive capability is only suitable for low power applications. However, I believe that in the near future will be elevated to high-power LED driver occasions.
Q:LED Street pressure is not enough, what will happen?
Potential safety problems, resulting in shortened service life, serious damage to the product directly.
Q:How many watts is the LED street light 30W-900M?
The power is 30W, and the 900M is the current.
Q:How much is the price of the LED street lamp?
It depends on the customer's specifications
Q:Can you tell me how to solve the problem of LED street lamp heat dissipation? Ask for an introduction
The biggest problem that hinders the popularity of LED lighting applications is the high price and high price of LED lights, which is due to the heat problem. And because of the heat problem, the current LED street lamp is developing on the edge of death. Shenzhen City Xin too light technology company to solve the problem of LED street lamp temperature rise from the source. This technique is based on current control completed. Main components: AC-DC power supply, LED intelligent driving module, feedback current driving part of the wick wick controlled module in intelligent LED, therefore, will not affect the AC-DC power supply. AC-DC power does not produce too much heat, as long as the design and production can provide stable current can be 24V/2A or 36V/3A. The construction is convenient: power supply and LED intelligent module can be installed in the lamp at the bottom of the wick is made can be directly installed on the common street. No loss, guarantee a year. Because the power and illumination invariant intelligent module installation at the bottom end of the lamp post, the lamp does not need waterproof. Can also use LED LED street lamp intelligent driving module: do not need to have the radiator shell power supply AC-DC:100 yuan, LED intelligent drive module: 300 Wick yuan (source module): 120 1W LED chip, every 1 yuan, or 120 yuan, coupled with the substrate, the processing fee is 200 yuan in profits, while the total 320 yuan.
Q:Why do street lights use bat wings to match the light curve?
Make full use of light. LED light is diffuse type, not only will be the problem of uneven illumination glare.
Q:What is the maximum power of a LED street lamp at present?
If it is integrated, this power can be achieved.
Q:Does the LED street lamp 80W or 100W need to be compensated by a single light capacitor?
Capacitor compensation is reactive power compensation or power factor compensation. The power system of electric equipment in use will produce reactive power, and is usually inductive, it will make use of the capacity of power efficiency, and by increasing the capacitance of the way properly in the system can be improved.
Q:Is there a place where trees can hold LED solar street lamps?
Yes, solar street lights are not covered by trees
