LED Tube Light Higher Efficiency, More Energy Saving, More Environmental Protection
LED Tube Light is a more mature LED Tube Lights, has now gradually replaced the traditional fluorescent tube, in the traditional fluorescent tubes compared. In the same brightness situation, LED Tube Light to save 80%. Not to be damaged, more durable.
Scope of application: supermarkets, hospitals, factories, cabinets and so on need lighting places.
For LED Tube Light over certification time, most of the organization requirements are single-end power supply, but why do we need to have one-terminal power supply? is the dual-end power supply LED Tube Light in the EU has a restricted export related documents? Does exporting the EU have to be a single end? is the double end feasible? Two-terminal LED Tube Light, the free end of the head may be charged, how to test this point?
is the power supply isolated or not isolated? There is no limit to this. Relatively speaking, the use of isolated power supply lamp, the output of the power supply is safe and low-voltage, the lamp shell and hand contact place can be regarded as a safe area, more easily through the detection of safety regulations; The disadvantage is that the transformer has large volume and the PF value and effect will be affected. The power input and output are not isolated when the non isolated power supply is used. Lamp is regarded as a charged body, so the requirements for creepage distance and insulation will be higher, specifically including the lamp and foot welding point between the solder joint and aluminum substrate between the distance of more than 5mm, lamp bead on both sides and aluminum substrate distance also requires more than 5mm.
Because the performance advantage of the non isolated power supply is very obvious and the cost is lower under the same condition, it is more competitive in the market if it can meet the insulation requirements and test through the pressure resistance. However, the performance of LED fluorescent tubes and safety regulation seems to be an uncoordinated pair of friends, when the fish and bear's paw can not be both, although, the production enterprises will therefore increase the cost, the personal point of view is to optimize the safety regulations.
The market controversy of LED fluorescent lamp Power Drive has the non isolation and isolation of 2 kinds of non-isolation advantages of low cost and high efficiency. On the LED light failure, the temperature effect is small but the requirements of the structure of the tube design insulation reasonable easily over UL, TUV, CE, PSE. Domestic non-isolated power supply over UL has 5. such as the isolation of the high cost of power, market competitiveness is not strong, a large impact on the LED life, at least a short 20% life. Because the component is more than the non isolation, the failure rate is relatively high, and the efficiency is much lower than that of the 78-82%, and the 87-95% efficiency is not isolated. From this point of view, the non-segregation will become the market mainstream in the future occupies an absolute advantage.
LED tube is also commonly known as LED light tube, LED fluorescent tubes, LED fluorescent lamps, its light source using led as a light-emitting body. The traditional fluorescent tube also known as fluorescent lamp, lamp at both ends of a filament, the lamp tube filled with traces of argon and thin mercury vapor, the tube inside the wall coated with fluorescent powder, two of the gas between the filament emitting ultraviolet rays, so that the phosphor emitting visible light. Because of the heavy metal pollution, "Mercury", so that the waste fluorescent tube to the environment pollution is very serious.
LED Tube Light using light-emitting diode as a source of light, more efficient, more energy-saving, longer service life, and more environmentally friendly. Become the most ideal replacement for fluorescent tubes at this stage. LED Tube Light and the traditional fluorescent lamp outside the size caliber are the same, have T5 tube, T8 tube, T10 tube, length has 0.6m, 0.9m, 1.2m, 1.5m, 1.8m, 2.4m.
