- Q: The structural difference between the LED low voltage band and the high voltage band
- In short, the line is the biggest difference! Low pressure is generally three parallel light bead! Yes, three open cuts! High pressure (except for one meter a customized)
- Q: Led how to solve the problem of strobe light?
- If your light belt is directly connected to the 220V power supply, this problem occurs, it must be the high voltage plug, the internal AC to DC converter is broken.
- Q: The brightness of 220V lights with LED power up before optical switch can adjust the lamp with the LED?
- The brightness of the LED light band cannot be adjusted.The high voltage light belt is made through IC or resistance capacitance step-down, and the security is very poor. Easy to cause fire and safety accidents, or use low voltage safety.
- Q: What color does the living room lamp belt use? What brand does the LED lamp bring well?
- NVC, three hung, Simon can not professional but want to buy a good point to pick Simon, really a bit with 3528 lights with NVC or three, the effect can also be, I played the effect. To cheaper online procurement, about 10 meters.
- Q: LED lights with 12 volts a meter, how many W?
- Power calculation method for LED lamp band:Power is the measure of the transmission rate of energy. In a DC circuit, it is the product of the voltage V and the current A; it is much more complicated in the AC system. Whether they are high voltage or low voltage LED light belts, they convert AC to DC to work.
- Q: Led how should I choose the light belt?
- There are many kinds of lights: LED flexible band, LED hard light strip, LED rainbow tube, can be called "light strip" or "light belt", I will talk about flexible lamp belt selection method:Look at this lamp with FPC, is also the circuit board, now a lot of businesses in order to save costs, the single copper has to do such a lamp with a long time, severe fever, LED life, is only a single panel you can see the back line (no LED this surface is smooth, the color is uniform) 2, double sided board have a line, a line of local color is deep, hands feel thick
- Q: LED how is the band embedded in the steps?
- LED (Light, Emitting, Diode) light emitting diode is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin. Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of the LED light shining. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
- Q: Excuse me, what brand is the best LED lamp band in China now? R?
- KingSun, Tongfang opto, Matsushita Panasonic, PHILPS PHILIPS, OSRAM OSRAM, CREE CREE, these are good, are on the list of LED lights on the good-best network brand ten brand ranking brand, you can refer to, the people around me to buy more is NPU crocodile and illumination of the two brands. A good price, you can focus on.
- 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: What is the difference between T4 tube and LED lamp? What are their advantages and disadvantages?
- T4 tubes, and they come in many forms, such as: 2U. Type 3U. Type.5U, 4U type, spiral type. And the fluorescent type. LED light is mainly light and long life
