So gradually into environmentally friendly, energy-saving LED lighting field, will help ease the energy crisis, environmental pollution situation.

Advantages of LED in many major cities such as Shanghai, due to peak in the summer, and decided to include the majority of the nightscape landscape lighting off, the disappointment to many admiring visitors. In so you want to enjoy the brilliant night of the summer, LED is a very good choice.

Rich, bright colors. The color LED product has covered the whole range of the visible spectrum, and good color, high color purity. Red and blue LED luminous efficiency of up to 20lni/W, red-orange range LED luminous efficiency of up to 100lm/W. and traditional way to color light incandescent bulbs and filters, incandescent light 820ltn/W, Filter light tablets of through rate as red filter light tablets of through rate for 0.06, so eventually of light effect far below color LED. table 1 several LED of main characteristics color material wavelength (nm) Center light strong (CD) light output light effect red red-orange yellow green blue LED of response time is short, General for several MS, can instantaneous reached full light pass output. If you use a combination of RGB LED, you can instantly change the color, is selected for dynamic lighting for fountains. LED dimming can also use RGB LED combination use PWM (PulseWidthModulator) to achieve a color gradient, such as used in building exterior decoration, more dreamy colors.
