LED is an abbreviation of English Light Emitting Diode. Its basic structure is a electrode -luminous semiconductor material chip. It is solidified by silver or white gum to the bracket, and then connected to the chip and circuit board with a silver line or gold wire.Then use epoxy resin to seal it to protect the internal core wire. Finally, the shell is installed, so the shock resistance performance of the LED light is good.
1. Expansion, use the expansion machine to evenly expand the entire LED chip film provided by the manufacturer, so that the LED grains that are attached to the surface of the film are opened tightly, which is convenient for thorns.2. Back glue, put the sculpted crystal ring on the crystal on the back glue camera with the silver paste, and the silver pulp on the back.Click silver.Suitable for bulk LED chips.Use the point -to -dote machine to put the appropriate amount of silver slurry on the PCB printing line board.
I. Introduction to the LED light belt refers to assembled LED on the belt -shaped FPC (flexible line board) or PCB hard board, named after its product shape like a band.Because of long service life (generally normal life span of 80,000 to 100,000 hours), green environmental protection, it has gradually emerged in various decorative industries.The lamp belt is the abbreviation of the LED light belt. Most people are not used to the noun when they say that they are too long, so they omit the LED in front, and it is called the light belt directly.The name of this lamp belt also contains the old -fashioned lamps that are directly connected to LEDs without FPC or PCB without FPC or PCB.
LED lights and energy -saving lamps
There is a lamp on the two ends of the ordinary fluorescent lamp, and the lamp tube is filled with a small amount of crickets and thin mercury steams. The inner wall of the lamp tube is painted with fluorescent powder. The ultraviolet rays are emitted when the two filaments are produced.Sofne visible light.The LED fluorescent lamp LED fluorescent lamp adopts the latest LED light source technology, digital design, with a power saving of more than 70%. The 12W LED fluorescent light is equivalent to 40W solar lamps (for town flows and Qihui.The power consumption is 42W to 44W).The LED sunlight life is more than 10 times that of ordinary lamps. It is almost exempted without maintenance. There is no need to change the lamp, ballast, and enlightenment.Green and environmentally -friendly semiconductor electrophoresis source, soft light and pure spectral spectrum, is conducive to user vision protection and physical health.
Advantages of LED lights
The internal characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses.1. The small LED is basically a small piece of chip was packaged in epoxy resin, so it is very small and very light.2. Low power consumption is very low. Generally speaking, the working voltage of LED is 2-3.6V.The working current is 0.02-0.03A.This means: it consumes no more than 0.1W.3. Under the appropriate current and voltage, the service life of the LED can reach 100,000 hours
What is LED light
LED (LightemittingDiode), light -emitting diode is a semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light.The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative electrode, and the other end connects the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.Semiconductor chips are composed of two parts, one is a P -type semiconductor. In it, the acupoints are dominant. The other end is N -type semiconductor. Here are mainly electronics.But when these two semiconductors are connected, a P-N knot is formed between them.When the current passs through the wire to act on this chip, the electrons will be pushed to the P area. In the P area, the electron and the acupoints will be compounded, and then the energy will be emitted in the form of a photon. This is the principle of LED light light.The wavelength of light is the color of light, which is determined by the material that forms the P-N knot.
