Q:What happens if the 12vled lights are connected to the 24V transformer?

The 12vled lamp with the 24V transformer will cause the led to burn out because the output voltage of the transformer is well above its rated voltage. Solution: the LED lamp is connected in series with a small sliding rheostat, regulator resistor, the voltage divider also can reach 12V.

Q:How do you calculate the current of the LED light belt?

The current band can be cut at any length, so most of them are 12V power supply in parallel.

Q:Why does the LED band suddenly go dark?

First of all, the power is battery, then please look at the battery, there is no electricity

Q:What are the specifications of the LED lamp band and which ones are more commonly used?

LED lamp belt refers to the LED assembly in FPC band (FPC) or PCB hard, because of the shape of the product as a band name. Because of long service life (normal life expectancy of 8~10 hours), green and gradually emerging in all kinds of decoration industry.

Q:How about the short circuit when the LED lamp belt is installed?

LED is the abbreviation of diode emitting light English, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core function, finally install shell so, the seismic performance of LED lamp is good. It can work in a high-speed state. If the energy saving lamp starts or closes frequently, the filament will blacken and soon break down, so it will be safer. It uses ultra bright high-power LED light source, with high efficiency power supply, more than 80% of the traditional incandescent Lantern Festival, the same power, brightness is 10 times that of incandescent lamp. Reduce line loss, no pollution to the power grid. LED use cold light source, glare is small, no radiation, no harmful substances in use. The working voltage of LED is low, and the DC drive mode is adopted. The ultra low power consumption, the electro-optical power conversion is close to 100%, and the energy saving is over 80% compared with the traditional light source under the same lighting effect. The environmental benefits of LED are better. There is no ultraviolet and infrared in the spectrum, and the waste can be recycled without pollution or mercury. It can be touched safely. It belongs to a typical green lighting source.

Q:Want to use LED light belt, put a layer of alternative eye protection lamp under the shelf, the effect is good?

The direct use of light with the words may have a little dazzling aluminum laminates can choose lamps with PC uniform lighting effect is good oh.

Q:What should I pay attention to when installing LED soft light belt?

Power connection method: LED lamp belt voltage is 12V DC, so it needs to use switch power supply, the power supply size according to the power of LED lamp belt and connection length to decide. If you do not want to take each LED lamp with a power to control, switching power supply can buy a relatively large power for the total power supply, then put all LED light with all input power in parallel (wire size is not enough, can also extend) unified by the total power switch. This advantage can be centralized control, inconvenient place is unable to achieve a single LED lamp band lighting effect and switch control, which specific way to be measured by their own.

Q:LED lamp with a whole such as bad if not how to detect the lamp with a lamp quality

Very simple, 2 battery 3V, each lamp does not light the ends of test, bad, LED is also a diode, try again when the reverse voltage is equal to the open circuit test for other beads, beads are measured

Q:Does the LED light come with a drive?

LED soft light with.LED soft light belt to drive power requirements almost harsh, LED unlike ordinary incandescent bulb, can directly connect 220V AC city electricity. The LED is a 2~3 volt low voltage drive. It is necessary to design complex conversion circuits for different uses of LED lights, equipped with different power adapters.

Q:Excuse me, what's the power consumption of the LED light belt?

Different light belt power consumption is different, the length of the lamp belt is different, and the power consumption is different. The common power consumption per meter is 1--5W. Suppose you're using 5W, and with 10 meters, the total power consumption is 50W. If you use 2W, 10 meters is 20W.
