Difference between LED light to Sodium lamp
POSTED ON APRIL 1, 2013 BY ADMIN IN LED KNOWLEDGE, LED LIGHTING WITH THERE ARE NO COMMENTS
The ordinary fluorescent lamp provides more green, about 50%, most of the rest are red and blue, which take about 25% of the total spectrum, infrared spectral ratio is very low. Fluorescent lamp with luminous efficiency 80lm/W, long life (about 12000h), and CRI>85, but less power (currently used both 28W and 36W). Because it contains a lot of green light, which likely to cause crop growth, commonly used in plant tissue culture.
The metal halide lamp is a gas light source, that mixed vapor of mercury and the rare metal halide, then generated arc, thereby discharge light. It can emit different spectral by changing the metal halide composition. Its luminous efficiency is high as 65-140lm/W, also high power, and long life (5000h to 20000h). But metal halide lamp contains mercury; it will pollute the environment when the lamp is breakdown or abandon. Its spectrum contains a lot infrared light, produces more heating, and also can’t shoot the crop in closed distance.
LED (Light Emitting Diode) is a solid-state semiconductor devices that can convert electrical energy into visible light; it can convert electrical to light directly. The heart of LED is a semiconductor wafer. And LED light is the lamps that used LED as light source. Compare to the up lamps, it’s have the following features:
1) High energy efficient: it can achieve 100-150lm/W.
2) Long life as 50000h.
3) LED light in theoretically, its spectral characteristics include the entire visible spectral range. Color Rendition Index is 70-90.
4) Environmental protection: it doesn’t contain mercury or xenon and other harmful elements, also does not produce radiation, it is recyclable.
Obviously, Countries all over the world take more and more attention to the problem of energy-saving and environmental protection, some countries are already promoting the use of LED lamps. As long as the of LED lamps cost reduce, and LED technology continues to improve, it will replace the fluorescent lamp, Sodium lamp, the metal halide light inevitablely.
