How much do you know about LED lighting?


Do you know what LED lights are? I believe many friends are not very clear about this concept, but they should have touched the LED light. At present, LED lighting is everywhere in our lives. Especially at night, all kinds of LED lights fill every corner of each city, bringing a very beautiful light show to the city. So do we know the characteristics of LED lights? Let’s take a look Look:

LED lamp beads are a kind of light-emitting diodes, semiconductors that can convert electrical energy into light energy. It changes the principle of incandescent lamp tungsten filament lighting and energy-saving lamp three-color toner lighting, and uses electric field lighting. The LED lamps can use DC220V voltage, no need for starter and ballast. The start-up time is short, without flashing. The main characteristics of LED lamps are:

1. New green environmental protection light source: LED uses cold light source, small glare, no radiation, no harmful substances in use. The working voltage of LED is low, DC driving mode is adopted, ultra-low power consumption (single tube 0.03~0.06W), electro-optic power conversion is close to 100%, and it is more than 80% more energy-efficient than traditional light sources under the same lighting effect. The environmental protection benefit of LED is better, there is no ultraviolet and infrared in the spectrum, and the waste can be recycled, no pollution, no mercury element, can be safely touched, it is a typical green lighting source.

2. Long life: LED is a solid cold light source, epoxy resin package, anti-vibration, there is no loose part in the lamp body, there are no shortcomings such as filament glowing, easy to burn, thermal deposition, light decay, etc. The service life can reach 30,000~10 Ten thousand hours is more than 10 times the service life of traditional light sources. LED performance is stable, can work normally in the environment of -30 ℃ ~ +50 ℃.

3. Multi-transformation: The LED light source can use the principle of three primary colors of red, green and blue. Under the control of computer technology, the three colors have 256 levels of gray and are randomly mixed to produce 256X256X256 (ie 16777216) colors to form different light. Color combination. The light color of the LED combination changes a lot, which can realize a variety of dynamic changes and various images.

4. High and new technology: Compared with the luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products, successfully integrating computer technology, network communication technology, image processing technology and embedded control technology. The chip size used in the traditional LED lamp is 0.25mmX0.25nm, while the size of the LED for lighting is generally above 1.0mmX1.0mm. The working table structure, inverted pyramid structure and flip chip design of LED die formation can improve its luminous efficiency, thereby emitting more light.

Innovations in LED package design include high-conductivity metal block substrates, flip-chip designs, and bare-die cast lead frames. These methods can be used to design high-power, low-thermal-resistance devices, and these devices have higher illuminance than traditional LEDs. The illumination of the product is greater.
