There are many kinds of table lamps on the market, and table lamps often appear in our lives. LED desk lamps are favored by consumers because they are beautiful and practical, with many advantages and disadvantages. What are the advantages and disadvantages of LED desk lamp? The following Melaleuca decorative network analyzes the advantages and disadvantages of LED table lamps for everyone.

Six advantages of LED desk lamp

The inherent characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it is widely used.

1, the light source has good directivity and can be illuminated on demand, so it is better as an emergency desk lamp.

2, small size, LED is basically a very small chip, encapsulated in epoxy resin,

So it's small and light.

3. The illumination is enough to meet your general lighting needs. 4, low power consumption LED power consumption is quite low, generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A, that is, its power consumption does not exceed 0.1w.

5, environmental protection, high efficiency and energy saving, LED is made of non-toxic materials, unlike fluorescent lamps containing mercury, which will cause pollution.

At the same time, LED can also be recycled. 6, no ultraviolet rays, no infrared rays. LED is durable and completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There is no loose part in the lamp body, which makes the LED not easy to be damaged. LED lamps are highly energy-saving: energy-saving and pollution-free means environmental protection. Dc drive,

Ultra-low power consumption (single tube 0.03-0.06W) electro-optical power conversion is close to 100%, and the equivalent light efficiency is more than 80% less than that of traditional light sources. Longevity: LED light source is called longevity lamp, which means a lamp that never goes out.

Six disadvantages of LED desk lamp: 1, high price, constant current drive, poor heat dissipation and easy light decay.

2, the lighting brightness is small, which is not suitable for large-area lighting.

3, led lights will also heat up and need to dissipate heat.

4. In the initial stage,

LED lighting is mainly used for large-scale landscape lighting, not suitable for high-eye environment. At present, it is mainly based on experiments.

5, led lights will also heat up and need to dissipate heat. LED can not be simply used as a common light source; Its use depends on the combination of driving power supply, optics and heat conduction.

6, LED lamp beads, after a few years of use, will slowly wear out and cannot be replaced, which will easily lead to the scrapping of the whole table lamp. I recommend: Huayi HY Lighting 20 12, the latest five brands of outdoor lamps with solid wood floors.
