Q: What, in what way do I shunt the LED?: The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.

Q: Is the forward voltage drop of the patch LED too large or too small?: Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you

Q: Patch LED beads can be bought in what place?: If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.

Q: LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?: L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.

Q: What is patch LED?: Patch element. Very small, no pins, soldered directly to the circuit board. For example, the keyboard lights in a mobile phone are used in this way.

Q: The quality of the LED patch module: Life。 LED's life is considered 100000H. In fact, LED products in 10 or 20 years to reach 100000 hours, and now the best LED life expectancy is only 50000 hours. Incandescent lamp for 1000 hours, fluorescent lamp for 2000 hours, neon for 10000 hours. The so-called "100 thousand hours" was only measured by scientists at room temperature at room temperature. After the formation of LED and chip packaging products, even the top of the chip, due to differences in the production of advanced packaging using the equipment, technical differences, the different forms of packaging, management, as well as the difference between the way users, resulting in life are not the same. Patch LED, life can reach 40000-50000 hours; piranha LED, life expectancy of 30000 hours, inline LED, life expectancy is 10000 hours. Of course, with the advances in chip and packaging technology, these data will gradually increase. The premise is that you understand an important concept, LED life means when the brightness of LED is 70% of the original brightness, we decide the LED life to this end.

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: What does "1210" mean in patch LED?: At present, most manufacturers of SMD light strip used by 3528 and 5050, and 3535 and 5630 in the majority, there are many of the 3528 and 5050 and 3535, such as patch LED used in automotive lighting.

Q: How do led patches measure good or bad?: LED patch how to measure methods: use two meter meter test, red pen is positive, black pen negative, if there is "bee" sound is bad, if the light is good

Q: SMD LED lamp working voltage?: Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage
