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.
Stainless steel screws used in advertising profiles are there?
Stainless steel screws advertising in our daily lives mortal mainly used to install some outdoor billboards, and many other factors profiles, structure, size, location of billboards is an important factor in the decision to use what kind of profiles installed stainless steel screws advertising, which Why stainless steel screws profiles have what type? Here let us take a look at it. Its stainless steel screws advertising there are three main sections: First, the austenitic stainless The most b
Stainless steel screws rusty
Stainless steel screws combinations in our daily lives is mainly used in electrical, electronics, machinery and equipment, electronics, shipbuilding, chemicals, water, and so many other industries, and its aim is to make it to the fastening device between product parts and components, but when put into use, through a long period of observation we will find a combination of stainless steel screws rusting phenomenon will occur, which it why would rust? Here let us take a look at it. Many people m
China is expected to diversify operations carried hardware
Contest these jobs are in the onset of furniture hardware changes, followed by improvements in the external environment, the company launched add experience, the quality of its all going. Low-grade furniture hardware company began focusing on quality and corporate culture, collaboration and communication between the companies has become even more frequently, the company about the brand also began to broaden and deepen the depth of excavation into segments consisting of representation fro
LED lights strengths
1, LED streetlights own characteristics - unidirectional light, no light diffusion, ensuring illumination power. 2, LED lights have a common secondary optical plan, the LED street light shines on the desired area lighting to further enhance the power of light to reach the energy-saving intentions. 3, LED light source power has reached 110-130lm / W, and there is still much room for development, the theoretical value of 360lm / W. The high pressure sodium light power is only being added wit
