WHAT YOU SHOULD KNOW ABOUT LED GROW LIGHTS?
Energy-efficient LED grow lights are the lighting of the future of agriculture. They are not only economic in their use but they produce better plants as well, in comparison to all traditional lighting options. In the texts below you can read how the LED grow lights work, how they affect plant growth and what advantages the LED lights have over the thus far most widely used artifical lighting in agriculture – HPS lamps.
WHAT ARE LEDS AND HOW DO THEY WORK?
LEDs (Light Emitting Diode) are small electronic components made of two different types of semiconductor material, one having a negative charge, called electrons, and the other having a positive charge, called holes. When voltage is properly applied over an LED, electric current starts to flow through it making electrons and holes start to collide releasing energy in the form of photons, light quanta, in a process called recombination. The first LEDs had relatively low light output and limited selections of colors while modern LEDs have high brightness and come in varieties of colors in visible, infrared and ultraviolet spectral ranges.
