The choice of plant fill light, there are two categories of application scenarios, household or professional agricultural planting fill light (such as plant factory, greenhouse), the latter involves much more optical design.There are fluorescent lamps, HID lamps and LED lamps available on the market. For any purpose, it is recommended to choose LED lamps.This is largely because, compared with the traditional plant lamp, LED lamp plant has the following advantages: high photosynthetic efficiency (energy saving), wide spectral range (easy to obtain monochromatic light or full spectrum), the spectral intensity is adjustable, long service life, less heat, can close lighting, saving space), lamps and lanterns form diversification, can meet the demand of different application scenarios), the use of security is higher.For example, in our experiments, vegetables that take 45 days to ripen in a natural environment were grown in 30 days with LED lighting.Take another chestnut: at present, the greenhouse is used more HID lamp, but HID lamp effect is not high LED, although THE price of HID lamp is much lower, but electricity consumption is the largest consumption in the cost of plant light.According to 600WLED compared with 1000WHPS (HPS is a HID lamp), the light quantum number of the two kinds of lamps is almost the same, but the annual electricity cost can save about 2300RMB, and the service life of a qualified LED lamp is 50000h, and the service life of high-pressure sodium lamp is only 3000h.In addition, before the purchase of plant light filling lamp, it is also necessary to understand some lamp parameters, including lamp power (related to the light filling effect, energy consumption cost), spectrum (affect the light filling effect), style, size, light body material, weight and light source type (related to the life of the lamp).If you are a household lighting demand, the purchase of the following suggestions: try to choose high light efficiency products.The higher the luminous efficiency of the lamps and lanterns, the better the luminous efficiency, not only save electricity, save air conditioning, save light, the irradiation effect is better;Light efficiency: refers to the efficiency of converting electric energy into light energy, expressed in μmol/J.For example, two 100W lamps with light efficiency of 1.75μmol/J and 2.5μmol/J respectively can produce quantum numbers of light that can be absorbed by plants of 100W *1.75μmol/J=175μmol/s and 100W *2.5μmol/J=250μmol/s.The effect of plant supplementary light lamp on plants is mainly reflected in the number of light quantum number that can be absorbed by plants.2. Pay attention to the uniformity of lamps and lanterns;3. Spectral ratio, such as the spectrum with a large red-blue ratio, has obvious effect on crop color and compaction, which will be illustrated in pictures later;4. Home fill light also need to consider chroma and eye protection, these factors are related to daily appreciation.If you are a professional agricultural grower, it is important to know your planting needs before buying a plant light bulb.What plants are to be filled with light?Because different plants have different requirements for light intensity and spectrum, it affects the power selection and spectrum customization of light supplement lamp.Spectrum customization: the spectrum of artificial light source is carefully designed according to the needs of plant growth. The professional plant filling lamp will customize the spectrum according to the needs of different crops at different growth stages, and the spectrum can obviously affect the effect of filling light.2. The area and layout of lighting filling area, which not only affects the choice of lamp power, but also involves the selection of lamp size and style;3. The space environment, such as the lighting conditions, shading conditions in the area, the height of the lamp can be suspended, etc., to provide reference for the selection of the lamp body material (such as UV resistance), light source type (hot light source or cold light source) and suspension bearing;4. Estimation of lighting cost, etc.The plant lighting market combines the physiological characteristics of plants with lighting lamps, and the products are different but the quality is also uneven. While considering the effect of light supplement, it is also necessary to consider the safety certification of lamps, the warranty period of lamps and after-sales service, etc. Professional problems should be given to professional people, so that professional people can speak with data.
