High-power LED lamp application is a multi-disciplinary integration, a lot of factors affect the product, including high-power LED lamp performance and parameters, industrial design, optical design, thermal design, circuit design, structural design, Production process and other links. In the design and production process must take full account of the relevant factors, any one part of the deviation will affect the product performance and effectiveness.
High-power LED lamp is a typical green lighting products, as the national green lighting to promote the use of high-power white LED light source is an inevitable choice. Its product features are as follows:
◎ high efficiency:
High-power LED table lamp luminous efficiency has been more than 100lm / W, but also because almost all of the LED spectrum focused on the visible frequency band, light efficiency is far greater than incandescent and is catching up with energy-saving lamps and fluorescent lamps. White LED spectrum see below Figure 1, fluorescent, incandescent, fluorescent light spectrum shown in Figure 2.
◎ high light quality:
As the spectrum is not ultraviolet and infrared, so there is no heat, no radiation, will not give people a burden, long time to read or work will not have the phenomenon of eye irritation.
◎ good color:
Compared with fluorescent lamps, high power LED lamp color rendering index is high, usually around 80. This will help reduce the degree of human eye fatigue, to protect the eyesight is of great help.
◎ low maintenance costs:
LED long life, luminous flux half-life of more than 50,000 hours, the general use of more than 30 years. Impact resistance and seismic capacity, no tungsten wire, glass bulb and other vulnerable parts, abnormal "scrapped" the possibility of very small.
◎ small size:
Can make the lamp small and exquisite, more suitable for different use of places.
◎ with the battery, it is easy to make desk lights emergency lights. When power outages or emergency situations, help people evacuate and illuminate.
◎ green:
Waste can be recycled, no pollution, unlike fluorescent lamps containing mercury.
