Why We Use LED Lamps for Outdoor Lighting From:www.lgiled.com   Reporter:summer   Date:2014/1/26 8:53:26   Tags:lcd-video-wall-solutions

The current domestic and international LED color standard is the basic reference the ANSI C78.377 standard, the color temperature is divided into 2 700K, 3 000K, 3500K, 4000K, 4500K, 5000K, 5700K, 6500K this several grades, and the provisions of the color tolerance range of Wen Yunxu. led downlight is usually according to the classification of color temperature, but the LED lamp is mainly used for outdoor lighting, color mainly in 2700K, 3000K, 4000K and 5700K these. Outdoor lighting are very gorgeous and polychrome and multi-colorful, this is all because of the LED lamp. LED lamp as the outdoor lighting appliances is quite energy saving and environmentally protectable, and it is very the popular. Among which, polychrome and multi-colorful led downlight is often used for short distance projection light, and ongoing dazzling characters of led ceiling light, is often used for long distance projection light.

Speaking of the polychrome and multi-colorful led downlight, it produces monochromatic light of great half width. As the semiconductor energy gap decreases when temperature rises, the peak emission wavelength of polychrome and multi-colorful led downlight rise and growth with temperature, for example, the spectral red shifts, the temperature coefficient will be +2~3 ℃. The polychrome and multi-colorful led downlight is of forward current with both luminance L and approximately proportion. The current increases, the brightness will also increase. In addition, the brightness is also related to the ambient temperature, when the ambient temperature rises, the composite efficiency will decrease, then luminous intensity decreases. With little current, the polychrome and multi-colorful led downlight won't rise temperature obviously. If the ambient temperature is high, the main wavelength will shift LED, the brightness will drop, so are the light uniformity and consistency of variation. Particularly speaking, the big screen lattice temperature rise on polychrome and multi-colorful led downlight reliability, stability is more obvious, so the thermal design is the key part of a polychrome and multi-colorful led downlight.

Ongoing dazzling characters of led ceiling light is quite controllable. When adjusting the current through the ongoing dazzling characters of led ceiling light, they can produce different colors. Such as a low current red led ceiling light, as the current increases, it will turn into orange, yellow, and green, quite a ongoing dazzling characters of led ceiling light. If coupled with digital control, can realize the dynamic effects blew. What's more, ongoing dazzling characters of led ceiling light is stable, no 50 Hz flicker, no ultraviolet B radiation. When lighting at the same time, ongoing dazzling characters of led ceiling light can also effectively protect the eyesight from hurt.

What's more, both polychrome and multi-colorful led downlight and ongoing dazzling characters of led ceiling light are quite environmentally friendly. LED lamp does not contain harmful elements such as mercury and lead (most of the ordinary lamp contains mercury and lead and other harmful elements), and does not generate electromagnetic interference (common electronic ballasts in energy-saving lamps will produce electromagnetic interference). Even if the recovery of waste products of polychrome and multi-colorful led downlight and ongoing dazzling characters of led ceiling light, they will not cause environmental pollution. With floodlights do facade lighting in many buildings, the biggest drawback floodlight is possible for pedestrians and building tenants cause light pollution, while the polychrome and multi-colorful led downlight and ongoing dazzling characters of led ceiling light are mounted directly on the exterior wall of the building height, irradiated to the outside of the building, will not caused light pollution to pedestrians and tenants do not.
