1, high purity, bright rich colors. LED products currently cover nearly the entire visible spectral range, and high color purity. The traditional way to obtain colored light is incandescent plus filter, greatly reducing the light efficiency.
2, long life. LED's actual life of over 5 million hours of light for the general several times or even several times.
3, no mercury lamp, UV-free beam. LED is a solid light source, green, especially for perfume shops, jewelry stores, museums, galleries and other professional establishments, the display of goods to meet their special requirements of lighting.
4, solid light, seismic performance, solid and reliable.
5, energy, economy, maintenance-free.
6, the dynamic color control, brightness adjustable, combination of the three primary colors of the LED PWM can be used to achieve the color change.
7, LED has a strong directional light, luminous efficiency is high, and the volume is small, easy-to-LED lighting design and control of light intensity distribution.
8, LED can be DC low voltage power supply, safe and reliable.
9, LED not start temperature limits, transient start, usually a few ms, and can reach full transient flux output.
