Q:How do you control the two LED lights with a remote control?
Don't know what you mean, just buy a double control of the remote control switch can.
Q:How to connect the LED lamp with constant current drive?
Both ends of the line is relatively early and also a common method, because of its convenient wiring, aging, simple and so on. So far, there are many LED lamp manufacturers. The two pins of the lamp cap are shorted together, then connected to the constant current power on the inside. Such a wiring method only needs to be removed from the traditional starter, so that it can work properly.
Q:Why is the LED patch band always flashing?
If the AC transformer is switched on, it will flash.LED patch lamp, also known as SMDLED, Chinese SMD LED or SMD LED, the purpose of packaging is to produce automatic placement machine can be used,The main models are 0402.0603.0805.1206.3528.3020.5050.3014.5730, etc.
Q:Which led light belt is less power saving? Is it easy to break?
I can say with certainty that the LED band is very economical. In general, we usually use LED lights with power 1.5W, 4.8W and 7.2W per meter.
Q:What's the brightness of the LED light band? Can I use it for lighting?
No, the light belt is auxiliary lighting. Mainly to create a spatial atmosphere.
Q:How does the PS make the band?
PVC lamp with the odor material, not because of the new lights will have, but the longer the taste is bigger, because the LED is sealed in the lamp belt, LED generated heat conduction in the plastic material, resulting in the issue of plastic taste. Maybe the quality of the products used by the landlord is a little bit worse. Generally, a good flexible band does not produce a big smell!
Q:LED how to connect the lamp band, 12 volt battery is not damaged
Direct contact will burn. The three should be connected in series, with 150 ohm resistors in front (power not less than 0.06 watts). Note the positive and negative poles, and the gap is negative.
Q:Where is the difference between the LED lamp belt and the ordinary lamp?
Electrical characteristics LED soft light belt power supply and incandescent lamp, fluorescent lamp is very different. The incandescent lamp can be directly connected to the alternating current of the 220V. Although there are ballasts and switches for fluorescent lamps, they also use 220V alternating current. The LED power supply requires a constant DC current, so the AC 220V is converted to dc. The efficiency of the power supply is not high, will directly affect the efficiency of the entire lighting, so improving the efficiency of the power supply is very important for improving the efficiency of the LED soft light band lighting.
Q:How do you calculate the current of the LED light belt?
Non lighting each group current is about 10~20mA., each 3 lamps are a group. Lighting type about 50mA a group (different manufacturers, the current is also different), then you see how many lights, divided by 3 to get the number of groups, the number of groups of single current can get the total current
Q:Ceiling LED lamp with controller output how many volts?
Yes! Have high pressure, also have mortgage. Usually 12V.
