What is an LED light and what is an LED light?

LED is the abbreviation of English Light Emitting Diode (Light Emitting Diode), its basic structure is a piece of electroluminescent semiconductor material, placed on a shelf with leads, and then sealed with epoxy resin around to protect the internal core, so the LED has good seismic performance.

As upstairs is complaining, this is the basic concept of LED.

As for the LED lamp, it is now more popular to use LED lamps.

You can look up on the Internet that LED lights have a lot of advantages.

LED lights have been a hot-selling product in the lighting market in recent years, and they are the best choice for many owners to light their homesWhat is LED light？How about LED lights? Below we will answer them one by one, hoping to be able to help you.

The so-called LED lamp is a kind of light-emitting diode as the main material to make lamps and lanterns for outdoor use, which can emit light, mainly because we use weak electrical energy to make the p-n junction of the semiconductor achieve the effect of luminescence, which means that we inject electrons into the p-region and n-region in the diffuse and widen the light source through radiation recombination when we have a certain forward bias voltage and current. Compared with traditional bulbs, LED lamps have the advantages of high luminous purity, low power consumption and ultra-long life.

LED is the abbreviation of English lightemittingdiode (light-emitting diode), its basic structure is an electroluminescent semiconductor material chip, cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, and then sealed with epoxy resin around to protect the internal core, and finally install the shell, so the seismic performance of the LED lamp is good.

How about LED lights?

Advantages of LED lights:

1. High efficiency and energy saving. Under the same brightness, LED lamps consume only 1 kWh of electricity for 1000 hours, ordinary incandescent lamps consume 1 kWh of electricity for 17 hours, and ordinary energy-saving lamps consume 1 kWh of electricity for 100 hours.

2. Ultra-long life. The theoretical service life of LED lamps can reach more than 10,000 hours, and the service life of ordinary incandescent lamps is more than 1,000 hours.

3. Healthy light. The light does not contain ultraviolet and infrared rays, no radiation, no pollution; Ordinary energy-saving lamps and incandescent lamps contain ultraviolet and infrared rays.

4. Green environmental protection. It does not contain harmful elements such as mercury and lead, which is beneficial to the use of mercury and lead, and will not produce electromagnetic interference.

5. Protect eyesight. LED lights are driven by DC power supply, no flicker, ordinary lights are AC driven, which will inevitably produce strobe is not good for long-term eyes.

6. High light efficiency. The heat generation is small, 90% of the electrical energy is converted into visible light, and only 20% of the electrical energy of ordinary incandescent lamps is converted into visible light, and the other 80% of the electrical energy is converted into heat energy, which is a great waste of limited resources.

7. High safety factor. LED lamps require less voltage and current, less heat, and no potential safety hazards, and can be used in dangerous places such as mines.

Disadvantages of LED lights:

1. Although the light attenuation of LED lamps is low, this is basically for high-power LED lights, while the light attenuation of low-power LED lamps is still relatively large.

2. The light color of the LED lamp is white light, due to the individual defects in the manufacturing process and the matching error of the lens, it is easy to form a yellow circle when used, which will affect the effect of the lamp.

That's all for you, what is LED light? How about LED lights? All of it.

1. The LED lamp is an electroluminescent semiconductor material chip, which is cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, sealed with epoxy resin around it, which plays the role of protecting the internal core wire, and finally installs the shell, so the LED lamp has good seismic performance.

2. LED can directly emit red, yellow, blue, green, cyan, orange, purple and white light.

3. At first, LED was used as an indicator light source for instrumentation, and later LED of various light colors was widely used in traffic lights and large-area display screens, which produced good economic and social benefits. In the United States, for example, a 140-watt incandescent lamp with a long-life, low-light performance was used as the light source, which produced 2,000 lumens of white light. After passing through the red filter, 90% of the light is lost, leaving only 200 lumens of red light.

In the newly designed lamp, Lumileds uses 18 red LED light sources, which consume a total of 14 watts of power, including circuit losses, to produce the same light effect. Automotive signal lights are also an important area for LED light source applications.

1. The LED lamp is a piece of electroluminescent semiconductor material chip, which is solidified to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, and sealed with epoxy resin spike bucket around it to protect the internal core wire, and finally the shell is installed, so the LED lamp has good seismic performance.

2. LED lamp function: used as household lamp. Many LED lamps can replace spiral incandescent lamps or energy-saving bulbs from 5-40 watts for Leeson and 60 watts for low-power incandescent lamps.

Some lamps can even replace higher power bulbs, such as a 13-watt bulb that is about as bright as a 100-watt incandescent lamp. LED bulbs are also available in different colours, but with lower power and maintenance costs.

3. White LED bulbs have high efficiency and have a leading position in the low-power market, such as flashlights, solar garden lights, pedestrian street lights, bicycle lights, etc. Monochrome LED lights are often used to make traffic lights and holiday lighting.

In our daily life, more and more common LED lights, such as households, cars, mobile phones, etc., it has become the protagonist in the field of lighting, with energy saving and environmental protection, high quality and low price, strong shock resistance, leakage prevention and other advantages, but what kind of light is it?

1. LED (lightemittingdiode), light-emitting diode, is a solid-state semiconductor device, which can directly convert electricity into light.

2. The heart of LED is a semiconductor wafer, one end of the wafer is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the whole wafer is encapsulated by epoxy resin.

3. The semiconductor wafer is composed of two parts, one part is a p-type semiconductor, in which holes dominate, and the other end is an n-type semiconductor, which is mainly electrons here. But when these two semiconductors are connected, a p-n junction is formed between them.

4. When the current acts on the wafer through the wire, the electrons will be pushed to the P-region, where the electrons will recombine with the holes, and then the energy will be emitted in the form of photons, which is the principle of LED luminescence. The wavelength of light, which is the color of light, is determined by the material that forms the p-n junction.

The above is the introduction of what kind of LED light is, do netizens understand it after reading it?
