Greenhouse fill light when to use, will have a good effect?

In the current field of plant cultivation and cultivation, fill lights have become an indispensable tool, especially in greenhouses, they provide an important light source for plant growth. Among these supplementary lights, LED lights and high-pressure sodium lamps occupy a mainstream position with their unique advantages.

First, let's talk about incandescent lamps. Incandescent lamp as a traditional lighting tool, its light-emitting principle is to heat the filament through the current, so that the filament heat and emit visible light. In the field of plant supplementary light, although incandescent lamps can provide a certain amount of light, they are gradually replaced by other more professional supplementary lights because of their low luminous efficiency, large calorific value, and unsatisfactory spectral distribution.

Next is fluorescent lighting. Fluorescent lamps use ultraviolet rays generated by low-pressure mercury vapor discharge to excite phosphors coated on the tube wall to emit visible light. Compared with incandescent lamps, fluorescent lamps have higher luminous efficiency and longer service life. In the aspect of plant light supplement, fluorescent lamp can provide more uniform light, but its spectral distribution is still not ideal, it is difficult to meet the specific needs of plant growth.

Then there's the high-pressure sodium lamp. High-pressure sodium lamp is a high-brightness, high-penetration gas discharge lamp. Its luminous principle is through high-voltage electricity so that sodium vapor discharge produces strong yellow light. In plant light supplement, high-pressure sodium lamp is favored for its high brightness, high penetration and long life. It can provide strong light and help to promote the photosynthesis of plants, but it also has the problem that the spectral distribution is not ideal.

Finally, we focus on LED grow lights. LED plant growth lamp uses LED as the light source, which has the advantages of high luminous efficiency, small calorific value and adjustable spectral distribution. In the field of plant light, LED plant growth lights can provide different wavelengths and different intensities of light according to the specific needs of plant growth, so as to better promote the growth and development of plants. In addition, LED plant growth lights also have the characteristics of energy saving, environmental protection and long service life, so they are widely used in greenhouse and other plant farms.

In general, incandescent lamps, fluorescent lamps, high-pressure sodium lamps and LED plant growth lamps have their own characteristics and have their application value in the field of plant light supplement. However, with the progress of science and technology and the continuous improvement of people's demand for plant growth, LED plant growth lights, with their unique advantages, are gradually becoming the mainstream choice of plant light.
