What indicators should be paid attention to in the design and purchase of LED plant lights
What kind of LED plant lights do plants need? Doing one thing is easy, but doing one thing is difficult. It is simple to make an LED plant light, but not easy to make an LED plant light. It is really not an easy task to design and manufacture a LED plant growth lamp that can really help plant growth, repellent and disease resistance, high efficiency and long life. It requires every detail to be done well, and Houyi energy-saving brings you What are the main indicators and performance of a good plant light? (1) Rationality of light distribution. The LED plant light chip (hereinafter referred to as the chip) that plays a direct role in supplementing light for plants. It can be said that all other parts of the LED plant growth light serve the chip. The rationality of light is almost entirely determined by the chip. The light distribution includes the chip spectrum and the chip matching. The chip spectrum is the luminous band after the chip is produced. The most important ones are the red light with the wavelength between 610nm and 720nm, and the blue and red light with the wavelength between 400nm and 520nm. Promote plant photosynthesis, mainly affect plant flowering and fruit; blue light enhances plant chloroplast activity, mainly affects rhizome growth. In addition, a small amount of white light, purple light, and green light are used together. Chip matching refers to the ratio of various waveband chips when the LED plant light is assembled. Strictly speaking, the ratio of the chips used for different growth periods of different plants is different, but considering that it is impossible to change it every few days The workload of batch plant lights is too large and the cost is too high. Therefore, according to whether the plant is planted mainly using its rhizomes or mainly using its flowers and fruits, in general, there are more red light chips than blue light chips. Increase the ratio of red light chips. The light distribution rationality of LED plant lights directly affects the formation of plant light. It is also a very important index that must be considered first in the production of LED plant lights, and it is also the most important parameter for judging the performance of LED plant lights. (2) Uniformity of illumination Every plant should receive light, and it is best that every plant can receive the same light. To put it a step further, at least the light intensity, light quality, and light duration of each plant should be roughly the same. It should be close, otherwise some plants will grow poorly due to insufficient light, and the other part will grow normally, but cannot fully use the LED plant light, which will cause unnecessary waste of resources. The main reason for the difference in plant growth conditions is the uniformity of illumination. The uniformity of illumination can be divided into the uniformity of the distribution of different light wave band chips in the LED plant growth lamp and the distance distribution between the LED plant lamps. The chip distribution is generally based on the LED plant light supplementary light plant characteristics. After the lamp bead ratio is obtained, how to intersect between the chips is calculated, and finally distributed on the plant light according to a certain rule and packaged on the COB panel, making a single unit LED plant lights illuminate the main area with uniform light quality and light intensity distribution. The arrangement of the spacing between each LED plant light is mainly determined by the light intensity of the edge of a single LED plant light. In addition, the installation height of the light must be considered. After comprehensive calculation, the distance distribution between each plant light can be obtained to ensure a large area. Uniformity of light during planting. Therefore, the uniformity of plant lighting is summarized as: uniform light quality and light intensity distribution in the middle and around a single LED plant growth lamp, and uniform light quality and light intensity distribution at the intersection between adjacent lights and other illuminated areas. (3) Luminous efficiency. Scientists are constantly working hard to increase the electro-optical conversion efficiency of each electrical equipment. The same is true for LED plant light researchers. As the world’s leading LED plant light industry service provider, Hou Yi is also Constantly pursuing and exploring methods to improve the conversion efficiency of point light, as well as methods that consume the same energy but can make plants grow better. Starting from human needs, there is a need for more energy-saving LED plant lights. The conversion efficiency of incandescent lamps is only 2-3% to that of LED plant lamps is as high as 20-30%. Working hard for the efficiency of electro-optical conversion, it seems that the LED plant supplement light field and the entire lighting field are stuck in this bottleneck at this time. LED is called the fourth-generation light source, and its energy-saving and environmentally friendly characteristics are really loved by thousands, but humans have never stopped making progress. Starting from the needs of plants, the luminous efficiency of LED plant lights is more important. Plant growth is not suitable for all spectra. They only absorb what they need. This requires us to produce LED plants from Starting from the actual needs of plant growth, it is best to provide the spectrum needed for plant growth at that time for each growth stage of each plant. Therefore, another feature of the high efficiency of LED plant lights is how to make plants grow better, yield and quality can be improved under the premise of the same energy consumption, which also includes the rationality of light distribution and illumination The uniformity. (4) Heat dissipation reliability Low-power LED plant lights do not need to take special heat dissipation measures, and only need to do a basic heat dissipation structure, because LED plant lights have high electro-optical conversion efficiency and relatively generate less heat, but LEDs are large. This is not the case with high-power plant lights. Although compared with traditional plant lights, the heat generated is much reduced, but compared with plant lights and plants, long-term use will not only cause great damage to the lamps, but also close exposure. There is a risk of burning plants, so special heat dissipation measures must be taken. Reliable heat dissipation performance can bring us the following convenience: (1) Relatively prolong the service life of LED plant lights, the service life of LED plant lights is about 50,000 hours. If the heat dissipation is not good, the internal structure will age quickly. The service life of lamps and lanterns will definitely be greatly reduced; (2) Luminous efficiency, any artificial light source has light decay, a very important factor that affects the light decay speed is temperature, high temperature will accelerate the aging of the material, also use a LED Plant lights, also used for 50,000 hours, one in a higher temperature environment, one in the temperature range of the safe lamp, the crops that are irradiated are undoubtedly the total yield and quality of the latter will be higher than the former. (3) The effective heat dissipation configuration of LED plant lights can also help control the ambient temperature. If heat dissipation measures are not taken for plant lights, the local temperature around the lights will be slightly higher for a long time, and the growth state of plants will definitely be different from other places. As a result, it is not conducive to the overall temperature control of the greenhouse or plant factory. When purchasing LED high-power plant lights, the reliability of heat dissipation is a very important technical indicator, which will have a direct and serious impact on the yield and quality of later planted crops. (5) Feeling of comfort An excellent product must have strong performance, and a perfect work must have a very enduring visual effect. How to judge the visual comfort of an LED plant light? Appearance is one of the factors, but the plant lamp is a functional product after all, and it is a little superficial just to judge by the appearance. Let's take a look at how to judge the appearance and comfort of LED plant lights: (1) Appearance, you read it right, it is the appearance of LED plant lights: Generally speaking, there are square and round shapes, which are acceptable to everyone. The rectangular shape needs to have a certain proportion to highlight the visual effect. It cannot be too thin, square or long. Then there is the thickness of the lamp. From the aesthetic point of view of modern people, a little thinner is more in line with popular habits. If the spotlight is made into an old-fashioned flashlight, it is not only inconvenient to use, but also inconvenient in appearance; if the panel type is used The increased thickness of the LED plant light makes it look like a light box, which not only affects the installation and movement, but also greatly affects the visual effect. (2) For light-receiving objects, it mainly refers to plants and people. To make plants comfortable, the first thing to do is to meet the growth needs of plants. Use LED plant lights to provide plants with the spectrum they like. When they grow strong, they naturally become comfortable. . For people, it is mainly visual comfort. According to the needs of plants, LED plant lights are composed of red and blue LED plant light chips. The purple light presented, coupled with the natural emerald green of plants, seems to be very strong. Brilliant breath. Although it looks good, the strong light of the LED plant light will have varying degrees of impact on the optic nerve of the animal. It is recommended not to turn on the light and look directly at it. In general, the comfort of the LED plant light is also a comprehensive consideration for purchasing LED plant growth lights, but the key is to be practical. After all, the existence of plant lights is mainly used to help plants grow healthily, not Come and watch. (6) Environmental applicability As the name suggests, before choosing to purchase LED plant lights, you must consider the field of your own planting, what kind of environment it is used in, and what kind of performance you need to have. The environmental applicability of LED plant lights can be roughly analyzed from the planting area, plant characteristics and plant growth environment. According to the size of the planting area, it is mainly decided to use the shape of the LED plant light. Generally, the LED plant growth light adopts the square and circular design. For a single plant, the round LED plant light can illuminate all the plants in all directions. Locally, it can not only meet the needs of plants for supplementing light, but also plant a single plant relative to the square LED plant light, and it will also reduce the waste of electricity and light energy. However, the opposite is true for large-area planting. Because of the large area and tight plant growth intervals, each plant is required to receive even light in every place. If a round plant light is used, the light at the junction of multiple lights cannot be guaranteed. A certain error range has no uniformity. On the contrary, the square LED plant light can solve the above problems very well. According to the characteristics of plants, positive plants need to provide sufficient light during the flowering/fruiting/rapid growth stages. At this time, LED high-power plant lights are often used to supplement light. If the plant is in the nursery stage and the light demand is not very high, then the LED plant light bar can meet its growth needs. The growth environment of plants varies greatly depending on the types of plants, and there will be huge differences in light, air, nutrition, humidity, etc. From the perspective of using LED plant lights, the main consideration is what kind of light the plant needs and how much light is needed. Already introduced. In addition, we must pay attention to some of the small features, such as: if it is hydroponics, the relative humidity of the environment will be relatively high, which requires the plant light to have a certain waterproof performance to avoid affecting the use effect of the LED plant light. The life of the lamp itself. The existence of a product itself is not good or bad. When placed in the right position, it is good. A plant lamp made of diamonds is used to illuminate a stone. Nothing is absolutely perfect. As a manufacturer of LED plant lights, Hooyi has been doing: discover the needs of users-meet the needs of users-feedback from users-solve problems encountered by users The problem-to provide better products and services-to provide users with better LED plant lights, to provide plants with better light nutrients.
