EFFECTS OF THE USE OF LED LIGHTING IN GREENHOUSES

People are increasingly concerned about the quality of the food, showing interest in the consumption of fresh food, at affordable prices, throughout the year. [...]a new era is envisaged for urban agriculture, where food is grown locally in limited spaces, without natural light.

[...]a new era is envisaged for urban agriculture, where food is grown locally in limited spaces, without natural light. [...]chlorophyll that has dropped an electron can accept an electron from another molecule (Willstätte R. 1912) This is the end of a process that results in the removal of an electron from the water. [...]in figure 2 is shown chlorophyll being - in the center of the oxidation reaction, a reduction, called photosynthesis between carbon dioxide and water, resulting in oxygen. Figure 3 shows an application that uses such a lighting system for intensive plant growth in a short time. Because the available LEDs emit light in different wavelengths depending on the manufacturing technology, the spectral complexity of the efficiency of photosynthesis must be understood and then an application developed. According to the recent developments in LED (light emitting diode) grow light technology, specific light wavelengths can now be isolated in order to control the different physical
