- Q: LED lights with a meter, about how much W?
- Each manufacturer because the chip is not the same, will cause the LED lamp working voltage and current is not the same. Therefore, the same band of rice LED lights on the market, their power will vary.
- Q: LED how much is the band of light a metre?
- At present, our company produces LED soft lamp with 30 yuan /M hard lamp, with 70 yuan /M
- Q: Which is good for low voltage lamp belts 5050 and 3014?
- Choosing 5050 or 3014 does not have much effect on the bandThe quality of the light belt is judged mainly by the chip, plate, brightness, heat dissipation and service life.
- Q: LED lamp belt, hot tin is not strong, what should I do?
- Find an iron and then welded, but. Some things about LED can focus on the "projective non bogey" public number, which has a relatively wide range of LED knowledge.
- Q: Troubleshooting of LED light belt
- Mainly from the following aspects to identify:1, look at solder joints. Regular LED lamp manufacturers with LED light band produced by SMT patch process, produced by solder paste and reflow soldering. Therefore, the solder joint on the LED light band is smoother and the solder flux is not much, and the solder joint is in an arc shape extending from the FPC pad to the LED electrode.2, look at the quality of FPC. FPC points of copper and rolled copper two kinds, copper plate copper is protruding out, look carefully, from the pad and FPC connection to see. The rolling copper is closely connected with FPC, and can be bent at any time without the phenomenon of pad falling off. If the copper plate is bent too much, the pad will fall off and the temperature will be too high to cause the pad to fall off.3. Look at the cleanliness of the surface of the LED lamp. LED band produced by SMT process, its surface cleanness is very good, can not see what impurities and stains. Hand soldering process to produce a cottage version of the LED lamp band, no matter how the surface cleaning, will remain stains and traces of cleaning.4. Look at the packing. The regular LED lamp belt will be packed with an antistatic coil tray, 5 meters roll or 10 meters roll, and the outer packing will be sealed with anti-static moisture proof packing bag. LED version of the cottage version of the band with recycled reel, there is no anti-static moisture-proof package, a closer look at the reel, you can see the appearance of cleaning labels left traces and scratches.5. Look at the label. Regular LED lights, bags and rolls have printed labels, not printed labels.6, look at the attachment. LED lamp with formal will attach instructions and specifications in the lights inside the boxes, also equipped with LED lights with a connector or card holder; not the accessories and LED lamp with copycat version of the box, because some manufacturers still can be saved.
- Q: LED lamp with 180 beads, how many watts per meter?
- The lamp lights with the general use of 20MA current, which is a is about 0.06W, so it is about 10W, but to consider a problem because there is resistance to limit the current, and therefore power resistance is not inside, if the use of low-voltage power supply (either 12V or 24V), its power 14.4W, which refers to the maximum power.
- Q: How to fit the proper driving power for the LED light?
- General LED lamp series, LED current generally at around 20 mA, the total power consumption of each P light = 220X0.02=4.4 watts. Power is electricity 220V.
- Q: Is the LED belt with a constant voltage transformer or a constant current transformer?
- LED lights with all kinds of varieties, with high and medium pressure, low voltage, AC and DC, lamp with internal general only by the current limiting resistor to protect the LED chip, is not reliable, of course, preferably with constant current drive lights, but seldom have this right drive, generally uses the switching power supply has regulated performance they are very sensitive to the change of the LED drive, the power supply voltage, the voltage variation of the weak will bring great changes in current, exceed the rated current of LED is very easy to damage. So the requirements of power supply better performance (in order to avoid the current instability), a better solution is to lower the power supply output voltage, the LED voltage derating, even if the impact is not accidental, overcurrent, caused damage to the LED, such as the low voltage of 12V can be adjusted to use low 11.5V. This will extend the service life.
- Q: According to the LED lights, how to judge the quality of the products?
- Look at the cleanliness of the surface of the LED lamp band. If the LED belt produced by SMT process, its surface cleanliness is very good, and no impurities or stains can be seen. However, if you use hand welding process produced cottage version of LED lights, regardless of how the surface cleaning, there will be traces of stains and cleaning, and at the same time on the surface of FPC will have soldering flux and tin residue.
- Q: Home decoration, lights band 5050 and 3528 what is the difference?
- The band refers to the LED lamp with a special process welding on copper or ribbon flexible circuit board, and then connected to the power supply light, because of its luminous shape such as a light band named.
