led colored lights are very colorful, colorful light in the middle of the night is extremely beautiful, plus it is very small, decorate the physical objects are more convenient, plus led colored lights are very durable, so many people like it very much.

led color lights price

The price of ordinary led color lights is generally 210 ~ 490 yuan. led color lights are also called LED color wall washer lights, using the fourth generation light source LED as the luminous body, long life, luminous color soft, bright colors, because of its shape for the long strip, also some people will be called LED color line lights, mainly also used for architectural decoration landscape lighting.

led color light principle

The basic structure of LED lights is a chip of electroluminescent semiconductor material, it is not through the atomic internal electron leap to light, but through the voltage applied to the ends of the PN junction of the LED, so that the PN junction itself to form an energy level, and then the electrons in this energy level leap and produce photons to light.The heart of the LED is a semiconductor wafer, one end of which is attached to a holder, one end is negative, and the other end is connected to the positive terminal of the power supply, so that the whole wafer is encapsulated by epoxy resin.The semiconductor wafer consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, on this side is mainly electrons.But when these two semiconductors are connected, a P-N junction is formed between them.When the current acts on this wafer through the wire, the electrons will be pushed to the P region, in the P region the electrons compound with the holes, and then it will emit energy in the form of photons, and this is the principle of LED lights emitting light.And the wavelength of light, which is the color of light, is determined by the material that forms the P-N junction.

led color light production

I.Material preparation. led colored light kit, can be purchased online, are very cheap, less than 10 yuan, as for the soldering iron and so on, students can go to the electronics laboratory or buy their own, online / electronic market is sold, the cost is but two.Thirty dollars, and once invested, lifelong use, and later can make other electronic products.II.Production process.1. Device inventory and measurement.Will buy all the materials on the table or test bench, according to the production instructions to count the devices one by one.Measure the resistance value of each resistor, with a multimeter, without a resistor can be marked by the resistance ring on the resistor, the corresponding calculation of resistance value.(1) five color ring resistors: the first ring indicates the first digit of resistance; the second ring indicates the second digit of resistance; the third ring indicates the third digit of resistance; the fourth ring indicates the power of the subdivision; the fifth ring indicates the error.(2) Four color ring resistors: the first ring indicates the first digit of resistance; the second ring indicates the second digit of resistance; the third ring indicates the power of the power; and the fourth ring indicates the error.
