High power LED is heading toward higher brightness and lower cost year by year. Ever since the invention of LED, its luminance increased by 30 fold while its cost decreased by 10 fold every 10 years, developing quickly toward becoming a high power, high light efficiency and low cost light source. Currently, the brightness of high power WLED in laboratory research can reach 100Lm/W and those which shines with 60Lm/W has already been put into commercial use in the market. With the advantages of power saving, long lifespan and environmental-friendly, high power LED has gained extensive attention from people and is gradually used in more fields. This passage is going to discuss its application in self-luminous advertisement signs, architectures with glass curtain walls and its application as underwater light sources.
1. High power LED used as underwater light source
The demand for underwater lamps in leisure squares and parks is large as waterscape and fountains are indispensable in these places. Traditional PAR light is commonly adopted as colorized underwater light source. But its light efficiency is low because of the filters installed in the lamps which are used to make the lamps colorful. On the contrary, the light efficiency of LED lamps is very high firstly due to the concentrated light beams thanks to its particular packaging technology and secondly due to its very small size that makes it adaptable to all kinds of optical lenses. Compared to traditional PAR lamps, LED underwater lamps can save power consumption for more than 13 fold. Generally speaking, high power LED used as underwater lamp is advantageous than traditional PAR lamps for its power saving trait, incomparable better light purity and saturation.
2. High Power LED used in self-luminous advertisement signs
Acrylic self-luminous signs that use LED as light sources in recent years have replaced neon lamps to become popular in many large cities of China. The disadvantages of traditional neon lamps are their high power consumption, inconveniency of maintenance and hidden safety problems; LED lamps not only overcome these shortcomings, but the light emitted is also saturated, uniform and tridimensional, predestining them to replace neon lamps and metal character advertisement signs.
3. High Power LED used in modern architectures with glass curtain walls
Architectural lighting method is usually adopted in the illumination of large piece of glass in modern architecture. This method integrates the light sources and building component, making the forms of lamps to become diversified, adding fresh idea to the lighting of architectures. Thanks to its high light efficiency, small size, design variety and conveniency of fixing, high power LED can provide an entirely new illumination solution for modern architectures.
LED illumination is an industry with huge development potential and bright future. With the improvement of packaging technology, heat dissipation technology, optical technology, application technology and control technology, LED lighting industry developed quickly. Along with its extensive application in different areas, high Power LED era will come at hand.
