Recently, I searched for things related to LED lights and found that many people still don’t know much about LEDs, so this article briefly introduces LEDs and their characteristics.
What does LED LED lights mean?
The full name of LED is Light-Emitting Diode. It is a semiconductor that can efficiently convert electrical energy into visible light. It emits light through the combination of electrons and holes. It is widely used in the field of lighting. led has changed the principle of incandescent lamp tungsten filament luminescence and energy-saving lamp three-primary color powder luminescence, and adopts electroluminescence. The characteristics of LED are very obvious, long life, high luminous efficiency, no radiation and low power consumption.
What are the characteristics of LED lights?
1. The characteristics of LED lamps:
LED lamp beads are a kind of light-emitting diodes, which can convert electrical energy into light energy. LED lamps can use DC DC220V voltage, without the need for starters and ballasts. Short start-up time, no flicker.
The main features of LED lamps are:
①New green environmental protection light source:
LED uses a cold light source, with low glare, no radiation, and no harmful substances are produced during use. The working voltage of LED is low, it adopts DC drive mode, ultra-low power consumption (single tube 0.03~0.06W), electro-optical power conversion is close to 100%, and it can save more than 80% energy than traditional light sources under the same lighting effect. LED has better environmental benefits. There is no ultraviolet and infrared in the spectrum, and the waste is recyclable, has no pollution, does not contain mercury, and can be touched safely. It is a typical green lighting source. How long do LED lights last?
LED is a solid cold light source, epoxy resin encapsulated, anti-vibration, there is no loose part in the lamp body, there are no shortcomings such as easy burning of filament, heat deposition, light decay, etc., and the service life can reach 60,000~100,000 Hours, more than 10 times the service life of traditional light sources. The LED performance is stable and can work normally under the environment of -30~+50oC.
LED light source can use the principle of red, green and blue three primary colors, under the control of computer technology, make the three colors have 256 gray levels and mix them arbitrarily, which can produce 256X256X256 (that is, 16777216) colors to form different light colors The combination. The light color of the LED combination changes many ends, which can realize colorful dynamic change effects and various images.
④High and new technology:
Compared with the luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products, which successfully integrate 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, and the size of the lighting LED is generally above 1.0mmX1.0mm. The working bench structure, inverted pyramid structure and flip-chip design of LED die molding can improve its luminous efficiency, thereby emitting more light. Innovations in LED packaging design include high-conductivity metal block substrates, flip-chip designs, and bare-disk casting lead frames. These methods can be used to design high-power, low-thermal-resistance devices, and these devices have better illuminance than traditional LEDs. The illuminance of the product is greater.
With the popularity of short videos all over the world, it has opened a window for people to see the world. There are some cool lighting videos on Tiktok. Many people want to know: What are the TikTok lights called? Are TikTok LED lights safe? What are the LED lights that TikTokers use?
Lack of knowledge. TikTokers uses a product called LED 7 colorful light strip, which is also a kind of LED light, which is very suitable for creating night scene atmosphere. This kind of light also applies the relevant characteristics of the above-mentioned LED, so it is also safe. If you have any other questions you want to know about LEDs, you can leave a message, and we will answer them.
