Interpretation of the four key technologies grim LED fluorescent tubes

2014-09-17 40

1 power supply is the primary requirement of high power, high power products, heat is low, the stability will certainly high. Usually isolated from the power supply, some useful and non-isolated two programs, isolated volume is too large, lower power, in use, the equipment will attack a lot of questions, as a non-isolated large market prospects of products, in which we talk about non-isolated primary drive solutions.

2.LED light source selection plan patented LED light source, the chip is placed in contact feet, heat over a silver foot node directly to the onset of tropical chips out of line with the traditional products, and traditional product placement in the heat there are not the same quality, the chip junction temperature will not attack cumulative, and then to ensure that the excellent use of light source lamp beads, lamp beads to ensure the number of longevity, low-light failure. Traditional patch product, although the chip through a gold wire connecting the positive and negative, with the onset of the thermal energy is excessive so that the chip is coupled to the gold silver feet, both thermal and electrical conductivity of money by conduction, the heat accumulation of a long time will directly affect the number of life LED fluorescent tube.

3 thermal infrared radiation heat introduced and used in fluorescent tubes, is an important way forward lamp use life numbers. In thermal considerations, we will heat the LED light source lamp beads distinguish heat and power, and do not bother, then ensure rationality heat. There are three ways to heat conduction, convection, conduction and radiation. In a closed environment, convection and conduction of the end may be small, and by radiation heat declared out fluorescent tube is a key consideration.

4 Security Security, where the primary PC retardant plastic tube says, because infrared heat can penetrate the PC pipe, we describe the use of LED lights when considering can more consideration their safety, physical insulated with plastic way, even if in the use of the non-isolated power supply must also ensure the safety of the use.
