Q:What is patch SMD-LED?
Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
Q:SMD LED lamp working voltage?
18 volts driven high 3030LED lamp (six core series, and 2 core, 3 core series and Design), driving power of up to 1W,1W high voltage 3030 LED (3 volts, 6 volts, 9 volts, 18 volts optional)
Q:What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?
At present, it is basically made of silica gel, and the epoxy resin is very few. Only those with lower price may use some. Why is it rare to use epoxy? Because of the use of LED epoxy patch cited some discomfort because the cable used in the above: reflow welding, high temperature resistant epoxy epoxy and silicone not lead to separation, produce decay dead lights etc..
Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Mold release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and is not soluble in contact with the chemical constituents of different resins (especially styrene and amines). Release agent also has heat and stress properties, not easy to decompose or wear; release agent bonded to the mold, and not transferred to the processed parts, without prejudice to painting or other two processing operations. Because of the rapid development of injection molding, extrusion, calendering, molding and laminating, the dosage of mould release agent is greatly improved.
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V
Q:The quality of the LED patch module
Quality of circuit board. In the same quality of LED, the quality of PCB will have an important impact on the life of LED. The circuit board is divided into aluminum plate, glass fiber board, semi glass fiber board and paperboard. The quality of aluminum is the best, the best cooling effect, but the cost is too high, the domestic manufacturers generally only in high-power LED products use, LED module manufacturers generally use cardboard, semi glass fiber and glass fiber board. Module, piranha, straw hat module monochrome is generally used in cardboard or semi glass, commonly used glass fiber or semi SMD glass fiber board. Colorful and full color module series generally at least half of glass fiber, so as to match.
Q:What is the difference between patch LED beads and LED beads: General
A pin of the lamp, and outside a resin cap, because the reason LED beads can spotlight cap;There is no pin on the patch and there is no resin cap outside. Because of the lack of cap, the LED patch can not be concentrated.LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
Q:Patch LED manual welding, how can welding not burn lights?
The welding speed and welding time because certainly give light foot heat, so the speed must be fast, tin wire and tip with better, while heating to tin iron head, avoid heating time is too long.
Q:What does "1210" mean in patch LED?
1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!
Q:Welding method and notice of SMT LED
It is best to use a hot-air gun heat transfer high air volume adjustable low moment welding, the specific heat jump to the appropriate place to see what you use what kind of welding wire, welding wire of different because of the different melting point impurities also some differences. The air volume is too high, easy to blow the original
