LED lamp is now a more common lamp products, mainly led. At the same time, mainly rely on semiconductor heterogeneity, electronic energy through some energy to produce a state of light, there are certain things, and the luminous process does not produce heat energy conversion efficiency, is also very high life is very long, mainly due to the development of lighting technology, LED lamp is mainly Durable energy saving as the standard, at the same time the advantages are very high, it is more practical.
The size of a single LED lamp is relatively small and can be made into any shape. The main feature of its LED is that it can replace the original traditional light source, has a wide range of uses, and its service life is relatively environmental friendly, non-toxic, and durable. Therefore, LED lamp is the most popular lamp type on the market at present.
LED fluorescent lamp is characterized by excellent quality, durability and energy saving, and its projection angle adjustment range is large. The brightness of 15W is equivalent to that of ordinary 40W fluorescent lamp. It is resistant to high temperature, moisture and water, and electricity leakage. Use voltage: 110V, 220V optional, cover glass or PC material. The lamp holder is the same as ordinary fluorescent lamp.
LED fluorescent lamp adopts the latest LED light source technology and digital appearance design, which can save electricity by more than 70%. The 12W LED fluorescent light is equivalent to 40W fluorescent tube (for ballast and starter, the real power consumption of 36W fluorescent lamp is 42W to 44w). The life of LED fluorescent lamp is more than 10 times that of ordinary lamp tube, almost maintenance free, and it is unnecessary to replace lamp tube, ballast and starter frequently. Environmental friendly semiconductor electric light source, soft light, pure spectrum, is conducive to the protection of vision and health of users. The 6000K cold light source gives people a cool visual feeling. The humanized illumination difference design is more helpful to concentrate and improve efficiency.
At present, compared with ordinary fluorescent lamps, LED fluorescent lamps have the following advantages:
1. Energy saving.
2. Long 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 ns (nanosecond) level response time, and MS (millisecond) level response time for ordinary lamps.
5. Environmental protection, no harmful metals, easy recycling of waste.
6. The color is gorgeous, the luminous color is pure, the spectral range is narrow, and it can mix red, green and blue into seven colors or white light.
Disadvantages:
1. The price is expensive.
2. At present, there is a big gap between the optical efficiency that can be generally achieved and the theoretical optical efficiency.
3. There is a big gap between the life that can be achieved and the theoretical life (10W hours).
4. There is still a certain amount of heat.
5. The light attenuation can be greatly reduced.
However, these shortcomings can be overcome by process improvement, so even if the current LED light source can not completely replace the existing traditional light source, with the development of technology, it must be led world in the future.
The above is a brief introduction of LED lamps and compared with traditional lamps, they have certain advantages, such as long energy-saving life, good applicability, mainly due to the development of lighting technology. LED lamps are mainly durable and energy-saving as the standard. At the same time, the advantages are also very high. Its practicability is relatively strong. For LED lights, the humanized illumination difference design is more conducive to concentration and improve work and learning efficiency.
