Patch light-emitting diodes, because of its high luminous efficiency, good stability, environmental protection, energy saving, and many other advantages, have been more and more popular. Moreover, the application of SMD LEDs continues to expand as market demand increases. At present, we not only see more SMD LEDs used in general lighting and commercial lighting, but more SMD LEDs are also used in a large number of street lamps, large parking lots, and indoor lighting.
It is because the SMD LED has the brightness, efficiency, service life, color temperature, and white point stability required for general illumination. Therefore, this type of SMD light-emitting diodes are used in most general lighting application designs, such as street lamps, parking areas, and indoor directional lighting applications. At the same time, because in these applications, LED-based lighting lowers the total cost of ownership (TCO) due to the lack of maintenance (because the lifetime of LEDs is much longer than that of traditional bulbs) and lower energy consumption. use.
According to statistics, there are more than 20 billion lamps in the world that use incandescent, halogen or fluorescent lamps. Many of these lamps are used for directional lighting, but all use lamps that emit light in all directions. According to the United States Department of Energy (DOE), in the new residential building, the light emitting diodes (LEDs) and ceiling lamps are the most commonly installed lighting fixtures. In addition, the DOE reported that ceiling lamps with non-reflective lamps are generally only 50% efficient, that is, half of the light produced by such lamps is wasted in the lamps.
In contrast, lighting-grade LED light-emitting diodes have efficient, directional lighting for at least 50,000 hours. Indoor lighting designed with all the advantages of lighting-class LEDs has the following advantages:
1. Efficacy over many existing incandescent and halogen lamps
2. Light Emitting Diodes Compatible with Even the Best CFL (Compact Fluorescent) Ceiling Lamps
3. Compared with ordinary lamps, SMD LED lamps need less maintenance and have a long life.
4. SMD LED lamps reduce the impact of light on the environment: no mercury, power station pollution, waste disposal costs are low, and environmental protection.
