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:Why solar energy centralized power supply street lamp must be supplied by AC LED lamp?
1: DC transmission distance is limited, the pressure drop is very high2: DC voltage - protection switch, controller parts and other technologies immature or cost slightly higher3: DC wiring voltage is not very high, but the street lamp power is not small, the current will be very high, the cable cost
Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program
If there are 20 or so parallel units. Each unit of parallel =0.18x30=5.4KW, 6mm - 10mm - copper or aluminum wire. Light controlled single-phase AC contactor 50A.
Q:What is the display index of the LED lamp?
The degree to which an object's color is rendered is called color rendering.Usually called the color rendering index (Ra)A light source with a Ra value of 100 indicates that the color displayed in the light of the object is consistent with that under the standard light source.
Q:What is the distance between the usual street lights?
There is no standard, and some are required to achieve the value of illumination, there is no hard and fast requirements, generally speaking, the distance between the street lamp and the lamp height and the number of watts.
Q:What should I pay attention to when buying street lamps?
Attention should be paid to the service life of LED street lamps. LED lamp life is relatively long, but affected by environmental factors such as light, LED lamp, life is affected, in the purchase of LED Street must understand clearly marked by the light LED lamp manufacturers and service life, good quality, light small, relatively long, the price will be high.
Q:The power supply of LED street lamp has no influence on the grounding power. The possibility that the power supply will burn out is not big enough
Ungrounded electricity generates static electricity and shortens the life of the lamp.
Q:How much is the LED street lamp with six meter pole?
The light pole is about 1000. Look what kind of lamp holder you want. There are 200 to eight hundred or nine hundred
Q:How to maintain the LED street lamp?
Cleaning: do not use liquid chemical cleaning of LED is unknown, because it may damage the surface of LED resin, and even cause the colloid cracks, if necessary, please put led into alcohol or fluorine in cleaning ang at room temperature, time in a minute.
Q:For the LED street light distribution, is it better to use a lens or a reflector?
According to personal needs, the last time I went to a lighting shop called Zhongshan Ming lighting shop to buy lights, but also asked the question, but do not remember what the salesman said
Q:Does LED street lights save electricity?
The white LED: in 1998, light white LED is only 5 LM / W, in 1999 has reached 15 LM / W, this index is similar to general household incandescent lamps, and in 2000, light efficiency of white LED has reached 25 LM / W, the index and the tungsten halogen lamp is similar. In 2005, the light efficiency of LED was up to 50 lumens / watt. In 2010, the light efficiency of LED reached more than 100 lumens / watt. The working current of white light LED can reach ampere level. Thus, the development of white LED writers using lighting sources, will become possible reality.
