Q:Why does the LED light change color?: 50 years ago, people had already understood the basic knowledge that semiconductor materials can produce light. The first commercial diode was produced in 1960. LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is an electroluminescentsemiconductor materials, placed on a wire rack, then sealed with epoxy resin around, to protect the internal core function, so the seismic energy LED.The core part of the LED is a wafer consisting of type P semiconductors and type N semiconductors. There is a transition layer between the P type semiconductor and the N type semiconductor, called the p-n junction. In some PN junctions of semiconductor materials, the injected minority carriers combine with the majority carriers to release excess energy in the form of light, thereby converting the electric energy directly into light energy. PN junction plus reverse voltage, the minority carrier is difficult to inject, so it does not emit light. The diode, produced by injection electroluminescent principle, is called light-emitting diode, commonly known as LED. When it in a positive state of the work (which ends with forward voltage), the current flows from the LED anode cathode, semiconductor crystals on the issue from the ultraviolet to infrared light of different colors light and the strength of the current.

Q:How to solve the problem of LED lamp out of light effect?: When the lamp band is too long, the brightness of the tail of the lamp belt is not enough1) use a more powerful constant voltage drive. Unlike 3A appliances, you can drive 3528 soft lights with 6 meters, but in order to prevent the tail of the light belt brightness is not enough, you can use 4A appliances, to ensure that the appliance has sufficient margin. But the power of the appliance doesn't need to be higher, otherwise it will waste.2) change the way the lights are connected. 6 meters of 3528, you can use 5 meters +1 meters in parallel with the lights, you can also 3 meters +3 meters combination of parallel.

Q:Embedded LED lights with notches generally go deep enough: It depends on what kind of band you buy3528505057303014 single row double row light bandThe width is usually 8101216 width

Q:LED can the band be cut at will?: Each of the 3 LED lamp 12VLED lamp with a module, modules can be arbitrarily cut.

Q:How do I choose the light belt?: LED lights with the second line, three lines, four lines, five lines mean?LED lamp belt according to the lamp belt, the internal cable is divided into round, second line, flat three lines, flat four lines, flat five lines four kinds.LED lamp a: tier with internal cable two, one line series lamp, and another is the wire. So there are two lines, line zero points, that is to say in the plug when the two needle is not bright, only the two pin plug inserted can turn 180 degrees again.LED lamp b: flat three lines with three line, two line series lamp, the two wires located on both sides. One of the middle is the power line. So the correct insertion is only to insert the pin into the wire. Unlike the second line and the four line, the plug has pros and cons.LED lamp c: flat four lines with four line, three line series lamp, one of which is in the middle of the wire. Therefore, the center of these two lines have zero, FireWire, that is, in the plug may be not bright, the solution is only four pin plug to 180 degrees, and then plug it.LED lamp d: flat five lines with five line, four line series lamp, the four wires located on both sides. One of the middle is the power line. So the correct insertion is only to insert the pin into the wire. Unlike the second line and the four line, the plug has pros and cons.

Q:How about the power of the LED lamp?: The use of resistance but also according to your current input voltage and depending on LED, because LED rated current is 20MA, but the actual application generally do not use 20MA, usually 15--18MA! To the series resistance, by Ohm's law can be counted by U=IR!So first you decide what kind of LED you use!

Q:Is the LED belt safe?: This line is best not to do any extension treatment, the cut may be thin after the good connection, you can extend the plug in front of the power line well. No-load voltage is not allowed, as long as the lamp can be used normally, do not measure it.

Q:Led and so on, or T5 tube well?: Now the house is decorated, LED. LED light tubes are also commonly known as light tubes and fluorescent tubes. Their light source uses LED as a luminous body. The traditional fluorescent lamp and fluorescent lamp, the lamp at each end of a filament tube filled with argon and rare trace mercury vapor, the inner wall of the tube is coated with fluorescent powder, ultraviolet radiation gas between the two conductive filament, the phosphors emit visible light. LED lights have many advantages, generally used in general lighting, office buildings, shopping malls, restaurants, schools, homes, factories and other indoor lighting.

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:Can the light belt be put on the plasterboard directly?: Yes, just fix the lights and prevent them from falling off.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.
