Q:Ceiling LED lamp with controller output how many volts?

Yes！ Have high pressure, also have mortgage. Usually 12V.

Q:LED which bands are suitable for use?

The main uses of LED soft light belts are: parks, gardens, buildings, roads, overpasses, cars, pools, advertisements, signs, interior decorations, neon lights, or beauty.

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

Let's put it this way. Neon and LED lights are two different sources of light. LED light is a light source applied by PN junction of crystal diode. The neon tube is attached to the tube by a high pressure gas plus fluorescent powder.

Q:LED lights with 80V induction, string, how many ohm resistance?

Understanding of the LED street lamp with a constant current per meter, you can accurately grasp the power output current problems, to avoid the output current is too large to cause LED breakdown phenomenon. Special note: LED lights with power use, we must pay attention to voltage, current, power these three factors, are indispensable

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:What type of LED lamp comes with the brightest light?

In two different manufacturers, using the same patch made of light, brightness may not be the same, LED is the current device, current is, the higher the brightness, some manufacturers in the pursuit of brightness and low cost, will increase the current to improve the brightness, life will be a lot worse, especially white. You can solve the problem that: 5050 led domestic manufacturers with some formal, ask the clerk to provide product specification, comparison of various manufacturers specifications on luminous flux values, a large number of lumens brightness generally high, of course, do not forget to consider the half angle.

Q:LED light is still a weak light after the switch is closed. What's the matter?

Check whether the switch is connected to the FireWire, if it is zero line, the LED light will be slightly bright, and the discomfort is to check whether the LED lights have any wires arranged and arranged on other wires. If the fire is left behind, it still turns on, and that may be caused by the induced electricity.

Q:Does the LED light band save energy?

LED lights must be more energy efficient than traditional ones, and the brightness is high

Q:Home decoration, lights band 5050 and 3528 what is the difference?

The first is the process of LED welding in copper wire above, then put the PVC pipe or equipment used in direct forming, round and flat two, named according to the number and the shape of the lamp wire belt to distinguish between two lines called, round in front with a round, round or flat line; in front with flat characters, namely flat line. Later developed into a flexible circuit board is used FPC as carrier, because of its simpler processing technology, quality is easier to control, longer life, higher brightness and color, and gradually replaced the earlier process, become the trend.Because the lamp belt is generally welded LED, so there are many LED lights, but because the noun is too long and simplified into a band.

Q:How to install the car LED lamp belt?

The four line LED lamp belt has four leads, three row lights (note not four row lights), each row 1 meters, 24 lights, 24 * 3=72. For each lamp power is 0.05W, power LED lights with 72 beads are: 72 * 0.05=3.6W.
