LED panel lights installed in the form of power
1, LED panel light power can be mounted on ceilings, walls and installing surface;
2, LED panel light power can be suspended below the ceiling or mounted body. When mounted on a white ceiling, the entire ceiling was the same color, very beautiful, clean and coordination;
3, LED panel lights power supply with wide voltage design (AC85-240V / 50-60Hz), can be used by countries in the world; high-power LED with isolated power supply, constant current or constant voltage drive, high power efficiency, power clean, performance stable, safe and reliable;
4, LED panel light source is similar LCD TV backlight technology a new type of surface light source, the light is soft, appearance, has been widely favored by European and American businessmen, a large number of foreign investors are Buying good quality, good service, good price panel lights products and suppliers;
5, LED panel lights power appears to be just a simple lighting models, but because of its high market positioning determines the customer's quality requirements for this product is extremely demanding, plus product itself comes to materials, thermal, optical, structural, fields hardware, electronics and other general corporate development team did not complete and sufficient experience in the development and subsequent supply chain management capabilities, it is difficult to develop a real success, coupled with the understanding of the market requirements are not clear, so a lot of development costs dropped to enchant to only one customer is not recognized product.

Selection Considerations LED power supply
First, the power margin
In order to increase the service life of LED power driver, you can choose 130% of rated output power based on load power models, such as when the LED load up to 30W, the proposed selection of the rated output of 40W LED power driver, it will give the power of long-term work in the more excellent condition, temperature not too high, which can effectively improve the LED power driver's life and reduce lamp temperature rise.

Two, safety and electromagnetic compatibility certification
Different countries around the world through certified LED power driver with better quality assurance, can provide the appropriate certification power than the test reports only provide more worthy of belief. There is a common European certification CE, UL GS and North America, ETL, Fcc and our CQC and so on.

Third, the protection function
With perfect protection function LED power supply drive can protect the environment at the time of mutation load poor contact and other accidents, to reduce accidents.
Common power protection function
OLP: Overload protection
OTP: Over temperature protection
OVP: Overvoltage Protection
OCP: Over Current Protection
SCP: Short Circuit Protection

Fourth, derating curve
Complete LED power driver product specifications will be accompanied by important parameters: derating curve, in strict accordance with the instructions of selecting power specifications
A: The temperature derating curves
According to different ambient temperature specification will give a clear load recommendations.
For example, the rated operating ambient temperature of 60 ℃ LED power driver, in accordance with the temperature derating curves, manufacturers may recommend at this temperature should be 70% load, ie the original rated output power of 100W at that temperature should not exceed the maximum load 70W.

B: Input derating curve
Above, according to the different input voltage, the power may have different maximum load limited. For example, a 100W power supply is rated input voltage range of 90V-240V, but recommend 80% in 90V, that is, the power supply is recommended at this time does not exceed the maximum load 80W.
