Led tube 1200mm T8 with isolation drive CE ROHS

Instruction :  why we choose isolation drive

   Nonisolation design is limited to double insulation product, such as lamp bulb’s replacement product, LED 

and the whole product are integrated in non conductive plastic that the user can avoid the dangerous of the 

electric shock. All of the secondary products are isolation product. But the price is expensive, but the product where the user can get in touch with the LED and output terminal(usual in LED lighting and streetlight lighting application ) is very common.

   With the isolation transformer or the electrical isolation LED drive power supply means that the LED can direct contact but will not electrical shock. But nonisolation transformer though can make part of the machine isolated with the help of the protective enclosure, the working LED can not direct contact.

  Most of the people always think that the non-isolation circuitry is the buck type, when the buck type circuitry damage that the LED also damage. Actually,widely used non- isolation topology is not only means the buck type, at least have three types, they are buck type, buckboost type and boost type. Each type of the circuitry have their characteristics. The buck type’s characteristicsis suitable for the topology of the highcurrent output, but apply to the LED, if the power source is damaged also leads the damage of the LED; Buckboost type’s charateristics is that the output voltage can up and down, such as MOS FET can not breakover ,LED also intact, widly used isolated flyback circuit is the devolopment of this circuit. Boost type is the pratical 

circuit that can get the higher output power and lower calorific value, also if the power source damage will not affect the LED,suitable for the drive project of the LED tube.

Q: Will wire leakage?

A:All our lamps, including wire through European Union CE and China 3c certification, please rest assured.

Q: Why the lighting so expensive?

A:(1)Process:  paint is the lacquer that bake, better than ordinary paint adhesion;Art (of choose and employ persons hand painted).

(2) the quality of paint: paint with good quality and environmental protection, health, paint for (rust).

(3) each part of the material with better, will better product quality, will also be expensive, like wire, we use is up to the standard of the United States and the European Union, flame retardant wire ignition point as high as 90 ℃, the paint is also meet the requirements of the Europe and the United States environmental protection paint.We do export products have 20 years, we are in accordance with the standards of export Europe and the United States to do these lights, not cut corners in this respect.

(4) the glass in the glass of the lacquer that bake, novel styles, color natural and lasting.

Q :How long is the warranty of the lighting??

A:The lighting's life has a lot to do with use of the environment, if used in damp and acid heavy space, on the surface of the lamp aging is relatively fast, like painting, in ordinary circumstances use 20000-30000 hours is no problem, if the environment is good, use50000 hours is also more normal.

Q: The products would be similar with the other company??

A:We all the lights were designed, and applied for a patent, not like other products.
