Company Information:

 Shenzhen Yuanheng Liquid Crystal Display CO., Ltd.

Shenzhen Yuanheng Liquid Crystal Display CO., Ltd. was founded in 1996,has nearly 20 years experience to manufacture and export  LED High Bay Light,LED Street Light,LED Exit Signs,Emergency Lighting,LED Industrial Light.All products reach theEuropean standards.

1. we have 3000square meters factory area.

2.have established  long-term and friendly patnership with CREE and Philips Lumileds

3.focus on developing high power LED light with high effiency,high CRI,non-electrolytic LED driver and phase-change cooling raditor .

4.provide OEM service for u

5.regard science and technology as the guides ,regard good quality of lights and service as the life of an enterprise.

6.Our team combines years of experience with passion of youth

 Factory and Machine:

  strength of Yuanheng Lighting:

 1.about the technolgy of Yuanheng LED high bay light:

  1)using phase-change cooling raditor

 This design can shorten the time to  conducte heat ,then the heat can be sended out from the cooling fin.

  2)cooling fins and heat pipe are designed to be combined.

   Using this design,it can reduce the gap between the pipe and fins, then can reduce the air resistance.

   3)using film capacitors LED driver

   Film capacitors can ensure the long life-span of the led driver,then can make sure the quality of the led light.

2.about the quality of Yuanheng LED high bay light:

  1)with imported philips lumileds LED light source   

Philips lumileds is one of the best quality led light source .

  2)all material reach the ROHS standerd

  We use the Rohs standerd material to protect the environment, and meantime to provide u the best products.

  3)adopt the pure aluminum for all parts

  Pure aluminum is one of the best material to conduct heat ,to ensure the long life-span of the led light

  4)designed to ensure the same  life-span of 50000 hours

  not only the led light source but the power and other parts of the light are designed to have the same long life-span.we promise supplying the best for u.

  5)Upto 100lm/w for energy saving

  high luminous efficiency can reduce the power consumption,less energy consumption is good for the environment.

3.about the feedback from customers

we have good friendship with our customers.

4.about our service 

1)your questions will be answered in 8 hours

2) In HK fair ,u will meet us,

 FAQ:

1.Q:what is  phase- change cooling technology?

   A: Phase-change cooling, also called vapor cooling, is a microprocessor-cooling technology that works according to the same principles as a conventional refrigerator, freezer or air conditioner.

With phase-change cooling, microprocessors can be chilled to temperatures at or below the freezing point of water. For this reason, humidity controls are necessary to prevent condensation of water vapor as dew or frost inside the computer housing. Phase-change cooling, while effective, is expensive. Most phase-change cooling systems also tend to be noisy although this problem can be mitigated by the use of acoustic shielding.The principal components of a phase-change cooling system are the compressor (or condenser), the vaporizer, the radiating element and the pump. In the compressor, a refrigerant gas condenses into a volatile liquid. The pump moves the liquid to the vaporizer, where the pressure is reduced and the liquid returns to the gaseous phase, absorbing thermal energy. When strategically placed in a computer system, the vaporizer can effectively remove thermal energy from the microprocessor and other critical components. The heated gas is then recycled through the radiating element and back to the compressor, where a new cycle begins. In this way, thermal energy is constantly removed from the computer components and transferred to the external environment.

In September 2008, Cray, the supercomputer company, announced a new type of phase-change cooling called ECOphlex (short for PHase-change Liquid EXchange) that is expected to enable multiple petaflop speeds and simultaneously save energy. Cray XT5 systems will ship with the new technology.

 2. Q:What is   film capacitors LED driver?

 A: An electrolytic capacitor is a capacitor that uses an electrolyte (an ionic conducting liquid) as one of its plates to achieve a larger capacitance per unit volume than other types. The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals and storing large amounts of energy. They are widely used in power supplies and in interconnecting stages of amplifiers at audio frequencies. An electrolytic capacitor will generally have higher leakage current than a comparable (dry) capacitor, and may have significant limitations in its operating temperature range, parasitic resistance and inductance, and the stability and accuracy of its capacitance value.

Film capacitor is electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes. The dielectric films, depending on the desired dielectric strength, are drawn in a special process to an extremely thin thickness, and are then provided with electrodes. The electrodes of film capacitors may be metallized aluminum or zinc applied directly to the surface of the plastic film, or a separate metallic foil overlying the film. Two of these conductive layers are wound into a cylinder shaped winding, usually flattened to reduce mounting space requirements on a printed circuit board, or layered as multiple single layers stacked together, to form a capacitor body. Film capacitors is one of  the most common capacitor types for use in electronic equipment, and are used in many AC and DC microelectronics and electronics circuits.

3.Q:what is your main market?

A:Our main market is European countries,we have many customers from Germany, UK, Sweden, Denmark, Spain and other Euro countries.

4.Q: How long is the delivery time?

   A:We usually delivery in 30-40 days after we get the deposit,if the quantity is much more then usually,we may delay the delivery date 3-5 days.

5.Q:How long is your warrenty?

   A:Our warrenty is 5 years,it's on the standard of reducing to the 70%brightness from exporting
