technical field

The utility model relates to the technical field of lighting fixtures, in particular to an intelligent LED plant growth lamp. the

Background technique

Light is an indispensable energy source for green plants to carry out photosynthesis. Only under the condition of light can plants grow normally, bloom and bear fruit. Photosynthesis of plants means that plants absorb sunlight energy with the help of chlorophyll, synthesize organic matter from carbon dioxide and water, and It is further converted into chemical energy and stored, and oxygen is released at the same time. The carbohydrates produced by photosynthesis are further converted into starch, fat, etc., which are needed for life activities. In a word, the growth of plants is inseparable from light. Or place lamps indoors, because the light utilization rate of the lamps used is low, which cannot meet the needs of plant growth, making the plants and flowers worse as they grow; when irradiating plants, using light that is suitable for the spectrum required by plants can not only promote their growth , but also can prolong the flowering period and improve the quality of flowers. Generally, the application environments such as home potted plants, indoor plant cultivation, and greenhouses are all indoors, and the relative light is insufficient, so that it is not conducive to the growth of plants. The growth of indoor plants must also increase the light source at night. The application of the light source system to greenhouses, greenhouses and other facility agricultural production can, on the one hand, solve the disadvantages of the lack of sunlight that causes the taste of greenhouse vegetables such as tomatoes and cucumbers to decline, and on the other hand, it can make winter greenhouse solanaceous vegetables go on the market before and after the Spring Festival. So as to achieve the efficiency of off-season cultivation. the

The photosynthetic pigments, water, biochemical components and structures contained in plants affect the special spectral response of plants. Chlorophyll a, chlorophyll b and carotenoids in chlorophyll can absorb the visible part of sunlight. Chlorophyll a and chlorophyll b mainly absorb red light, blue light and far infrared, while carotenoids mainly absorb blue light. Healthy plants have lower reflectance in red and blue light regions, and higher reflectance in near-infrared light regions. The photosynthesis of plants begins with the chlorophyll in the chlorophyll cake absorbing red and blue light in visible light red, orange, yellow, green, blue, and purple. Not all light is effective for photosynthesis of plants, and the effective part is concentrated in the visible light region , and the most effective ones are red light, blue light and far-infrared light. Chlorophyll has a relatively large absorption value in these two places, so red light can promote the rapid growth of plants, blue light is conducive to the formation of plant morphology, and far-infrared light can promote the growth of plants. Can affect plant flowering. Through red light, blue light and far-infrared rays, a series of subsequent chemical reactions are promoted to generate energy. Light quality mainly affects the shape and function of leaves, so most of them use lights that are close to natural light to simulate sunlight and promote photosynthesis. Different lights have different color temperatures. Plants need light to grow more lush. The effect of light on plant growth is the absorption of light by plant chlorophyll, the accumulation, absorption and utilization of carbon dioxide nutrients and synthetic carbohydrates. After research, it is found that the energy values of blue light, red light and far infrared are very close to the efficiency curve of plant photosynthesis, and the efficiency for green plants is even more significant. It is the best light source for plant growth and is conducive to the growth and development of plants; Generally, plants need blue light, red light and far infrared light, these kinds of light waves help plants to carry out photosynthesis. The advantages of red light are fast, convenient, simple, accurate, energy-saving, pollution-free, long life, etc. and can detect multiple parameters at the same time. Red light is not only beneficial to the synthesis of plant carbohydrates, but also accelerates the development of long-day plants. Blue light It accelerates the development of short-day plants and promotes the synthesis of proteins and organic acids, while short-wave blue light and ultraviolet rays can inhibit the elongation of stem nodes and promote the growth of multiple side branches and buds, and far-infrared rays have penetrating power and are effective on plants. It is quite helpful, but in the existing technology, the traditional bulbs and sodium gas lamps used have high electricity costs, and there is still a gap between the color temperature and natural light. The wavelength produced by the mercury lamp is 313-4BOnm, so the mercury lamp will not produce Red light, and the wavelength produced by the sodium gas lamp is 565nm, so the sodium gas lamp will not produce blue light. While using traditional light bulbs and sodium gas lamps to illuminate plants, because the traditional irradiation light does not contain a lot of red light and blue light, The growth efficiency of plants is not high. In addition, sunlight cannot be simulated around the clock, that is, plants cannot be provided with reasonable spectral irradiation all the time. At the same time, the time for irradiating plants will be increased, and the increase in power consumption will lead to waste of costs; In the current energy crisis, how to save energy is the most important condition before alternative energy is clearly and widely used. the
