In the field of plant cultivation, LED lamp has the following characteristics: abundant type of wavelength, which coincides with the spectral scale of photosynthesis and light morphology formation of plants; the width of spectral wave is half-width and narrow, pure monochrome light and composite spectrum can be obtained according to need, and the LED lamp can concentrate the light of specific wavelength to illuminate the crops equally. LED lamp manufacturers are environmentally friendly and do not have harmful substances of mercury.
The assembly parts of the LED bulb can be easily disassembled and assembled, and can be recovered by others without the need for manufacturer's recycling. No strobe. Pure DC operation eliminates the visual fatigue caused by stroboscopic light source. Reduce line loss, no pollution to power grid. Power factor (> 0.9), harmonic distortion (< 20%) and EMI meet the global target, which reduces the power loss of power supply lines and avoids high frequency interference pollution to power grid. The semiconductor wafer of solar LED lamp consists of two parts, one is P-type semiconductor, in which holes dominate, the other is N-type semiconductor, in which electrons are the main part. But when the two semiconductors are connected, a P-N junction is formed between them. When the current acts on the chip through the wire, the electrons are pushed to the P region, where the electrons recombine with the holes and then emit energy in the form of photons, which is the principle of LED lamp luminescence. The wavelength of light, the color of light, is determined by the material that forms the P-N junction.
LED lamp has remarkable energy saving. With ultra-high brightness and high power LED light source and high efficiency power supply, it can save more than 80% electricity than traditional incandescent lamp, and its brightness is 10 times of that of incandescent lamp at the same power. Its super-long life is more than 50,000 hours, more than 50 times that of traditional tungsten filament lamp. Led adopts high reliable advanced packaging technology eutectic welding to fully guarantee the long life of LED. The luminous visual efficiency can reach 80 lm/w. The color temperature of various LED lamps is optional. The color rendering index is high and the color rendering performance is good.
Plant lamp can not only regulate the flowering and Fruiting of crops, but also control plant height and nutrient composition. The system has the advantages of small heat and small space. It can be used in multi-layer cultivation system to realize low heat load and miniaturization of production space. In addition, the strong durability of LED lamps also reduces operating costs. Because of these obvious characteristics, LED lamp is suitable for planting in plant tissue and other controllable equipment environment.
