Table lamps are a must-have in our daily lives. Almost all families have one. Placing a table lamp at the bedside can facilitate nighttime activities. In addition, the desk is also a place where you can often see it. With the continuous advancement of technology and the continuous improvement of people's living standards, the functions and styles of table lamps have become diversified. Table lamps have developed from their original single reading function to the present, and have become a decorative artifact for ordinary families. As for the light source of table lamps, it is no longer the original single incandescent lamp. Halogen tungsten lamps, fluorescent lamps and LED light source table lamps are also commonly available on the market. Each of the four light sources has its own advantages and disadvantages. Next, let's introduce the characteristics of LED high-power table lamps.
1. High efficiency
The luminous efficiency of high-power LEDs has exceeded 45 lm/W. Moreover, since the spectrum of LEDs is almost entirely concentrated in the visible light band, the luminous efficiency is much greater than that of incandescent lamps and is catching up with energy-saving lamps and fluorescent lamps.
2. High light quality
Since there is no ultraviolet and infrared light in the spectrum, there is no heat, no radiation, and no burden on the human eyes. There will be no pain or swelling in the eyes when reading or working for a long time.
3. Good color rendering
Compared with fluorescent lamps, high-power LED desk lamps have a higher color rendering index, usually around 80. This helps reduce eye fatigue and is very helpful in protecting eyesight.
4. Low maintenance cost
LED has a long lifespan, with a half-life of more than 50,000 hours, and generally more than 30 years of normal use. It has strong impact and seismic resistance, and has no easily damaged parts such as tungsten filaments and glass shells, so the possibility of abnormal "scrap" is very small.
5. Small size
It can make the lamps small and exquisite, and more suitable for different places of use.
6. Green and environmentally friendly
The waste is recyclable and there is no pollution, unlike fluorescent lamps which contain mercury.
Excellent LED lamps must not only have high-quality electrical components, high-efficiency reflectors and reasonable structures, but also high-quality high-power LEDs. Only a good high-power LED can create a high-grade, high-end LED desk lamp, and reflect the high-end and modern feel of the product.
