Plant fill light principle
LED plant fill light is a kind of plant light, which uses light-emitting diode (LED) as the light source and replaces sunlight with light according to the law of plant growth to create a plant growth and development environment. LED grow lights help to shorten the growth cycle of plants. The light source is mainly composed of red and blue light sources, using the most sensitive light bands for plants. The red light wavelengths use 630nm and 640-660nm, and the blue light wavelengths use 450-460nm and 460-470nm. These light sources can allow plants to produce the best photosynthesis, so that plants get the best growth state. Light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation.
Features of grow lights
1. Efficiently convert electrical energy into radiant energy.
2. High radiation intensity, especially low infrared radiation (thermal radiation), in the effective range of photosynthesis
3. The emission spectrum of the bulb meets the physiological requirements of plants, especially in the effective spectral region of photosynthesis.
Arrangement of fill light time
1. As a supplementary light, the light can be enhanced at any time of the day, and the effective lighting time can be prolonged.
2. Whether at dusk or at night, it can effectively extend and scientifically control the light required by plants.
3. In the greenhouse or plant laboratory, it can completely replace natural light and promote plant growth.
4. Completely solve the situation of watching the sky and eating in the seedling stage, and arrange the time reasonably according to the delivery date of the seedlings.
