Which prawns will introduce what LED lights are

LED lamp refers to light-emitting diode, which is mainly composed of five materials: bracket, silver glue, wafer, gold wire and epoxy resin.

LED technology can be used in the fields of financial institutions, education, transportation, electricity, industry and commerce, taxation, commerce, sports and other fields.

Hunan New Yasheng.

The application of LED production is now very wide, it is a small diode, and then it can be made into light sources and other products, which can be used in luminous words, display screens, flashing signs, energy-saving lamps and other products.

LED white light is the most useful. But it doesn't work to use it directly. It must be used in the field of application. That is, it is to be developed into a finished lamp.

The introduction on the first floor is too clear, I can only say that if you need LED, look for me Ainia Technology ****.

There's still a lot of use for it.

Home improvement, engineering, outdoor. Both. Engineering lamps are the most profitable. Hey.

Home decoration, we Chinese still like to buy energy-saving lamps, although he is not cheap, but everyone thinks that he is energy-saving.

Engineering lights, outdoor large-scale lighting, decorative LED power saving, no need to repair for several years, no need to change bulbs or something. Although the lamps and lanterns are expensive, for enterprises, buildings, and street lamps that are lit up all night, energy saving is the most important thing.

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.

LED is English Light

emitting

The abbreviation of diode (light-emitting diode) is a semiconductor that can convert electrical energy into visible light, which changes the principle of tungsten luminescence of incandescent lamps and the luminescence of tri-primary toners of energy-saving lamps, and uses electric field to emit light. 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. Fifty years ago, the basics of how semiconductor materials can produce light were understood, and the first commercial diode was created in 1960.

The core part of the light-emitting diode is a wafer composed of p-type semiconductors and n-type semiconductors, and there is a transition layer between the p-type semiconductor and the n-type semiconductor, called the p-n junction. In the PN junction of some semiconductor materials, when the injected minority carriers are recombined with the majority carriers, the excess energy is released in the form of light, thus directly converting electrical energy into light energy. The PN junction is added with a reverse voltage, and a few carriers are difficult to inject, so they do not emit light.

This kind of diode made by using the principle of injection electroluminescence is called light-emitting diode, commonly known as LED.

When it is in the forward working state (that is, the two ends add the forward voltage), when the current flows from the LED anode to the cathode, the semiconductor crystal emits light of different colors from ultraviolet to infrared, and the intensity of the light is related to the current.

Second, the characteristics of LED light source.

The characteristics of LED light source are very obvious, long life, high light efficiency, no radiation and low power consumption. The spectrum of LEDs is almost entirely concentrated in the visible light band, and its luminous efficiency can reach 80 to 90%. The LED was compared with ordinary incandescent lamps, spiral energy-saving lamps and T5 trichromatic fluorescent lamps, and the results showed that:

The luminous efficiency of ordinary incandescent lamps is 12lm w and the life is less than 2000 hours, the light efficiency of spiral energy-saving lamps is 60lm w and the life is less than 8000 hours, the T5 fluorescent lamp is 96lm w and the life is about 10000 hours, while the white LED with a diameter of 5 mm is 20 28lm w and the life can be greater than 100000 hours. Some people also ** that the upper limit of the future LED life will be infinite. Specifically, it is manifested in the following aspects:

1. Voltage: LED uses a low-voltage power supply, and the power supply voltage is between 6-24V, which varies according to different products, so it is a safer power supply than using a high-voltage power supply, especially suitable for public places.

LED = Light Emitting Diode, light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light.

It changes the principle of tungsten luminescence of incandescent lamps and the luminescence of three primary color powders of energy-saving lamps, and uses electric field to emit light. According to the analysis, the characteristics of LED are very obvious, long life, high light efficiency, no radiation and low power consumption. The spectrum of LEDs is almost entirely concentrated in the visible frequency band, and its luminous efficiency can exceed 150 lm W (2010).

The results show that the luminous efficiency of ordinary incandescent lamps is 12LM W and the life span is less than 2000 hours, the luminous efficiency of spiral energy-saving lamps is 60LM W and the life span is less than 8000 hours, the light efficiency of T5 fluorescent lamps is 96LM W and the life span is about 10000 hours, and the white LED with a diameter of 5 mm can theoretically exceed 150LM W and the life span can be greater than 100000 hours. Some people also ** that the upper limit of the future LED life will be infinite.

However, the working principle of LED lamps makes the problem of heat dissipation in the high-power LED lighting industry very prominent, and many LED lighting solutions do not pay enough attention to heat dissipation, or the technical level is limited, so the actual service life of high-power LED lamps in mass production is generally far less than the theoretical value, and the cost performance is lower than the embarrassing situation of traditional lamps. In order to improve the service life of LED lamps and lanterns and truly achieve commercial mass production, the LED lighting industry is stepping up the development of new thermal conductive materials, such as thermally conductive plastics, independently or in cooperation with professional thermal conductive material manufacturers.

It's the lights anyway. You can use any land. We have this in our house. It's very convenient. Compared to the lamps produced by the United States, they light up as soon as they are turned on.

LED is very popular now, I only know that the brand of SCOE is good.

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

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.
