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 can I install the patch LED lamp belt on the wood chip casting board? With double-sided glue will be hot, and can not use the clip on the screw, what should I do?

With double-sided adhesive, the temperature will not be very high. So it won't fall either. That's how I got it. It took me more than half a year, and I didn't have any problems

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.Patch is based on small power, the shape is relatively small (usually 0.5 and 0.5W products)It's called patch because some small ones need Mounter to machine.The ordinary LED lamp, solder joints than SMD beads, now is the largest artificial welding. Regular watts count from 1-300W

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:Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?

The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim

Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?

Table 1, contact electrostatic protection LED product should be covered with protective electric tape, and its reliable grounding; 2, personnel shall wear groundstrap in contact with LED (best for cable, protective gloves, anti-static ring) allows better wear anti-static clothing, anti-static shoes and static electricity cap; 3, the application in the process of exposure to LED equipment must be reliable grounding, such as iron, shearing machine, bending machine and welding equipment. Conditional still can install plasma fan to eliminate electrostatic; 4, in use or when designing electronic circuit, must consider the harm that excessive current has to LED

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:How to detect LED SMD beads

Now the LED lamp, drop it in general about 3V, so the general multimeter is not measuring it.

Q:Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?

Patches do some high-end things, large luminous area, from afar to see more clearly, 5-10 meters with patches better!

Q:What are the storage requirements of SMT patch LED (LED)?

Clean? use no designated chemical liquids to clean SMD LED. These chemicals may damage SMD LED.. When necessary, wipe LED at room temperature with alcohol and dry at room temperature for 15 minutes before use? the effect of ultrasonic cleaning on SMD LED is related to the ultrasonic power and the SMD LED assembly method, and shall be checked in advance to ensure that the ultrasonic cleaning process does not impair the SMD LED
