What is LED light

LED lamps are a common type of lamp nowadays. They are mainly light-emitting diodes. At the same time, they mainly rely on semiconductor heterogeneity. Electrons can produce a luminous state through some energy. They also have a certain energy conversion efficiency and do not generate heat during the luminescence process. The lifespan is also very high. Mainly due to the development of lighting technology, LED lamps are durable and energy-saving as the standards. At the same time, the advantages are also very high and their practicability is relatively strong.

The volume of a single LED lamp is relatively small and can be made into any shape. The main feature of LED is that it can replace the original traditional light source, has a wide range of uses, and has a relatively long service life. It is environmentally friendly, non-toxic, sturdy and durable. Therefore, LED lamps are the most popular type of lamps on the market.

LED fluorescent lamps are characterized by high quality, durability and energy saving. They have a wide range of projection angle adjustments and the brightness of 15W is equivalent to that of ordinary 40W fluorescent lamps. High temperature resistance, moisture and water resistance, and leakage resistance. The operating voltage is available in 110V and 220V. The outer cover can be made of glass or PC. The lamp holder is the same as that of an ordinary fluorescent lamp.

LED fluorescent lamps use the latest LED light source technology and digital appearance design, saving more than 70% of electricity. The light intensity of a 12W LED fluorescent lamp is equivalent to that of a 40W fluorescent tube (for ballast and starter, the actual power consumption of a 36W fluorescent lamp is 42W to 44W). The life of LED fluorescent lamps is more than 10 times that of ordinary lamps. They are almost maintenance-free and there is no need to frequently replace lamps, ballasts, and starters. The green and environmentally friendly semiconductor electric light source has soft light and pure spectrum, which is beneficial to the user's eyesight protection and physical health. The 6000K cold light source gives people a visually cool feeling, and the humanized illumination difference design is more conducive to concentration and improved efficiency.

At present, compared with ordinary fluorescent lamps, the advantages of LED fluorescent lamps are as follows:

1. Energy saving. 2. Long service life. 3. Good applicability, because the size of a single LED is small, it can be made into any shape. 4. The response time is short, which is at the ns (nanosecond) level, while the response time of ordinary lamps is at the ms (millisecond) level. 5. Environmentally friendly, no harmful metals, and waste is easy to recycle. 6. The colors are brilliant, the luminous colors are pure, the spectrum range is narrow, and it can mix the three primary colors of red, green and blue into colorful or white light.

Disadvantages: 1. Expensive. 2. There is still a big gap between the currently generally achievable light efficiency and the theoretical light efficiency. 3. There is still a big gap between the current lifespan and the theoretical lifespan (100,000 hours). 4. There is still a certain amount of heat generated. 5. The light decay can be greatly reduced.

However, these shortcomings can be overcome through process improvements. Therefore, even though LED light sources cannot completely replace existing traditional light sources at present, with the development of technology, LED will definitely dominate the world in the future.

The above is a brief introduction to LED lights and they have certain advantages over traditional lamps. They are energy-saving, have a long lifespan and are good in applicability. This is mainly due to the development of lighting technology. The main standards of LED lights are durability and energy saving. At the same time, their advantages are also very high and their practicality is relatively strong. For LED lights, the humanized illumination difference design is more conducive to concentration and improves work and study efficiency.
