What lamp is used for indoor flower cultivation lighting?

Suitable light sources for plants are: high-pressure sodium lamp, metal halide lamp, ceramic metal halide lamp, microwave sulfur lamp, plasma lamp, fluorescent lamp, electrodeless lamp and LED.

Use 1400 watt lamp to illuminate at a distance of 2 meters from the plants. For the sake of economy, you can also use 100 ~ 300 watt white fluorescent lamp. When this light source is close to plants, it won't burn them. Incandescent lamps have high heat energy and may burn plants at close range. Shading method: shade with reed curtain, shade yarn, or put it in the shade.

In recent years, LED plants have developed rapidly, mainly red and blue LED beads, represented by enterprises in Shenzhen and other places. However, the pink LED plant fill light with LED red and blue combination has low color rendering, which is not conducive to protecting people's vision, especially not suitable for the plant fill light of ecological garden hotels.

At present, domestic technology companies have developed a full-spectrum lamp, which can simulate the color temperature change of sunlight in different time periods. The light color is warm in the morning, white at noon and warm at night, which can simulate the color temperature change of sunlight in the process of plant light supplement.

It can make plants absorb light with different wavelengths, which is beneficial to plant growth. The full-spectrum lamp has ultraviolet and far-infrared spectra, which is beneficial to improve plant sugar and taste.

Plant led fill light lamp:

According to the above principles, plant lamps are basically made into three forms: red-blue combination, all-blue and all-red, so as to provide red-blue light and cover the wavelength range required by photosynthesis. Visually, the red and blue combination of plant lights is pink.

White LED lamp, the most common is to excite yellow phosphor with blue core, thus producing visual white light effect. In the energy distribution, there are two peaks in the blue region of 445nm and the yellow-green region of 550nm. The red light of 6 10 ~ 720nm needed by plants is very scarce. This explains why plants are not conducive to growth under the irradiation of white LED.

Generally, the chromatographic ratio of red and blue lights of plant lamps is 5: 1 ~ 10: 1, and the ratio of 7 ~ 8: 1 can be selected. Of course, if possible, it is best to adjust the ratio of red to blue light according to the plant growth cycle.

When LED plant fill light lamp is used for plant fill light, the power of LED plant fill light lamp is generally less than 50wLED, and the height of different plants from the main leaf surface of plants is 0.2 ~ 0.8 meters. The plant fill light lamp with power higher than 50wLED should be used at a height of 0.5 ~ 1.5 m from the main leaf surface of the plant according to different plants.
