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:What is the material of LED lamp belt?

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. The light belt is the abbreviation of the LED light belt. Most people are not accustomed to the noun when they say it is too long, so the LED in front is omitted. It is called the light belt directly. In this way, the band with the name also includes a lot of big, second line, big three lines, round, second line and so on, the direct use of wire to connect LED, instead of FPC or PCB old band, of course, also includes flexible light band and hard light belt.

Q:What are the differences and connections between LED lights, light strips, hard lights, flexible lights, neon tubes, etc.?

And the workmanship is different. There are many differences in the effect of decoration

Q:LED is the light belt good? What lamp does the home outfit take well with?

Ordinary LED lamp with light source is a bit weak, suitable for use in the rest space, such as bedroom, advanced LED lamp with light source can, the price is very expensive, and some 100 per meter, you can use T5 lamp tube place, there is T5 tube. The most important point is that the light source to choose warm white Oh! Neutral light

Q:Is the LED belt with a constant voltage transformer or a constant current transformer?

Constant current transformers are generally current transformers. The principle of current transformer is based on the principle of electromagnetic induction. The current transformer consists of a closed core and windings. The number of the primary winding turns its little string in the current need to measure the line, so it is often all two line current flows through the primary winding turns are more connected in series of measuring and protection circuit, current transformer in operation, the two side loop it from the beginning to the end is closed, so the measurement instruments and protection circuit impedance in series with the coil current transformer is very small, close to the working state of short circuit. The current transformer is to change the primary side large current into two side small current to measure, the two side can not open circuit.

Q:LED lamp and lamp with high and low points?

I don't understand what you say,The normal white light source is the basic 3V to light, if you give a 2.7/2.8V or to light up, but if you give a 1.5V is absolutely not bright,It depends on his volt ampere characteristics,We should look at how much light with a lamp, and on a few a few,

Q:Does the LED low voltage lamp belt belong to the luminaire?

Does not belong to decorative lighting products. Lamps and lanterns, in fact, refers to the lighting products that have changed the light distribution. LED bulbs are not light fixtures according to laws and regulations. They are listed as light sources.

Q:What's the LED band?

LED lamp belt price is generally in meters as a unit, cheap 10 yuan or so: quality is more general, can do home decoration, or other use time comparison case use. The quality is better, the quality is about 30~50, and its service life is longer

Q:Does the LED light come with a drive?

LED soft light belt AC driver, according to different applications, are divided into buck, step-up, converter type of three circuit types. The difference between AC drives and DC drives is that there is an isolated and isolated problem from the security point of view, in addition to the need for rectifying and filtering the AC input.LED soft light belt DC driver can be divided into three kinds according to their different functions and uses.

Q:Which of the 12 volt LED light band and 220 volt LED lamp is brighter? What's the difference in electricity costs? Want to use it in the mall counter, 12 volts

12V is commonly known as low voltage line, and 220V is high voltage line.A few years ago, high voltage line technology is not mature, low voltage line can be broken, a chip at worst, in series near the other 2 (3 string). And then the high voltage line is bad, one will be bad on the whole meter.Later, the high voltage line technology mature, and now also three chips in series, pay attention to the procurement, ask the relevant personnel, do not buy the oldest high-voltage wire products on it. When I was 12, the hotel project was still using 12V, and now I've switched to 220V altogetherBrightness of the big difference, cheap 5-6 meters per meter (I have seen the cheapest, 2 meters a meter, no warranty), relatively bright manufacturers, ex factory price is 13. 5050 patch specifications, if you use high brightness chip wafer. (it's hard to find on the market.)
