LED plant lights can efficiently produce the light needed for plant growth, which is very important for space planting. Space planting requires reasonable use of energy, forming an independent circulation system, and using the least energy to keep the system running. The LED plant light technology is the technology that optimizes the growth of plants, and the high efficiency of LED lighting. Because when resources are scarce, you can get many photons with less energy. LED lights can also be used to produce special wavelengths necessary for plant growth.
Conditions required for long-term space missions
If we want to achieve manned missions to Mars and beyond, we must overcome many important technical obstacles. Building a spacecraft that can send astronauts to a star system outside the solar system is one of the problems we need to face. Ensuring enough food for astronauts during the journey is almost a daunting challenge.
Energy-saving and high-efficiency advantages of LED plant lights
The gardens on the earth may be unruly and messy, but in space, we always need vegetable fields to operate like machines in good condition. Many researchers can also produce unpalatable crops by scientifically using the mixed light of LED plant lights. Space planting research humans have made impressive results, but there is still a gap between practical applications.
Most of the organic matter on the earth is produced by photosynthesis between plants and sunlight. If you want to replicate the light conditions on the earth in space and use limited energy to generate light sources for plant growth and development, LED plant lights are the best choice. Light-emitting diodes want to produce less heat in the process of emitting light for other lighting equipment, so the luminous efficiency of light-emitting diodes is much higher than that of other light-emitting devices, producing the same measurement of light, LED The electricity used is much lower than other traditional lamps. Studies have found that when lettuce is grown indoors, red and blue LED plant lights are placed on the top of the greenhouse. The ratio of red to blue is 95:5. Under this special mixed light, lettuce matures consumes less energy, which is relatively traditional. The full-spectrum LED growth lamp saves 50% of energy, compared with other traditional growth lamps, it saves 90% of energy.
Traditional plant light are not suitable for space cultivation
If humans are to be sent to space, we must take every environment in this process seriously, because a little negligence may cause catastrophic consequences, so the research on space cultivation must be perfect, and the simulated environment must be real. If we want to propose a self-sustaining human settlement on the moon or Mars, or send astronauts to more distant space for missions, we not only need space vegetable plantations to provide basic food for life, but also have reasons for recycling Independent and sustainable closed-loop ecosystems such as carbon dioxide, oxygen and water. NASA has already acknowledged this need and is preparing to make this direction a key research and development direction.
Life in space is very different from life on earth. In space, the necessary environment for our lives will become very rare and precious, including air, water and sunlight. Growers in space will face many huge challenges. For example, traditional methods require traditional plant light of 600-1000 watts to simulate sunlight and stimulate plant growth in a closed environment. Traditional lighting also generates a lot of heat, which is not easy to diffuse in space, and the accumulation of heat is not conducive to the growth of plants and the maintenance of the environment. Lighting accounts for about 90% of energy demand. If calculated based on such energy demand, a nuclear reactor is needed to feed 4 people.
Many cannabis growers and laboratory researchers have discovered that LED plant lights are the best choice. Plants can only absorb certain energy from sunlight, and most of the energy is wasted. Among the different colors of light, plants prefer red and blue the most. After the laboratory transformation, the researchers found that under the irradiation of a small amount of blue light and a large amount of red light, the yield of lettuce was the largest, and the energy consumed was one-tenth of that of ordinary plant light.
LED plant lights are the best choice
The long-term space mission is a difficult challenge. There are many difficulties that must be solved in this process. Among them, the source of food in space is the basic condition, and it is also a problem that does not need to be solved. Scientists have built a growth room, dimming the LED system, controlling variables and other environments, and want to use this experiment to find the best conditions that can be installed on the International Space Station. Through the control of light to regulate the growth cycle of plants, some specific wavelengths of light can accelerate the growth of plants, make the metabolism of plants faster, shorten the life cycle of plants, we can get harvest in a shorter time, get more food in a shorter time. Adjusting the wavelength and intensity of light can not only optimize the yield of plants and the growth time of plants, but also adjust the content of vitamins, chlorophyll and other nutrients in plants, and can improve the taste. This experiment provides a possibility for our space cultivation.
Looking to the future
Although we have made great progress in indoor planting, we still have a long way to go before we are growing in space. At present, we only cultivate plants that have a simple growth environment and are easy to grow. For some plants that are rich in nutrients and relatively complex, The accumulation of plant cultivation experience is not enough. At present, for astronauts, vacuum-packaged food is the best choice, but the goal of mankind will never be satisfied with the existing exploration of the universe. The vast universe, stars and sea are what mankind wants to conquer. It just so happens that our company MOKOLight is a professional LED manufacturer. We are willing to contribute our strength to the progress of human civilization, and we hope that the LED plant light we produce will be available in space cultivation in the future.
