LED how much do you know about perpetual lamp knowledge?

The five essential pillars of plant growth are temperature, water, nutrition, air and light. As the saying goes, everything grows by the sun. What should we do when we encounter such bad weather as haze and rainy days? Plant growth lights can help us to replace the sun's environment for plant growth and development.
 
 
 
 
However, like people, plants need exercise, work and rest, so when using LED plant lights to make up light for plants, we should also control the time. Generally, it is recommended that the time of plant lighting should be controlled between 12-16 hours, so as to leave enough time for plants to rest, so as to ensure the work efficiency of plants at work every day.
 
 
 
The quality of light also has a very obvious effect on the growth of plants at all stages. For example, flowering and fruit bearing plants need sufficient red light in the flowering and fruit bearing period. If the red light is not enough, the light intensity can not reach the ideal effect no matter how large, which affects the flowering and fruit bearing rate of plants.
 
 
 
 
 
If we can match all kinds of light according to the needs of plants, the effect will be totally different. It can not only shorten the growth cycle of plants, but also improve the yield and quality of plants. This is also the reason for the emergence of plant lights, and the reason why LED plant lamps replace traditional perpetual lamp.
 
 
 
 
When the time and light quality are reasonable, it is necessary to use LED plant lights to control the light intensity. If the light intensity is not enough, the photosynthesis and respiration of the plant can not even reach the same level, and it is impossible to grow the plant.
 
 
 
 
If the light intensity is too strong, and there are too many points beyond the light saturation point, it is a waste of electric energy, and there is no need, so the most ideal state is to control the light intensity around the light saturation point, so that plants can grow healthily at the fastest speed.
 
 
 
 
 
Effects of spectral range on Plant Physiology
 
 
 
 
 
The matching parameters of light source for 14 kinds of common vegetables:
 
 
 
 
(1) lettuce: the red and blue light sources of 5:1 and 7:1 are the most suitable for its growth.
 
 
 
 
(2) the weight ratios of height, stem diameter and leaf width of leek treated with red / Blue 7:1 were significantly higher than those of other treatments.
 
 
 
 
(3) cucumber: 7:2 is the best ratio of red and blue light for the growth of cucumber seedlings, and 7:1 is the best ratio for the growth period.
 
 
 
 
(4) green vegetables and cabbage: 7:1 is the best ratio of red and blue light for the growth of green vegetables and cabbage leaves.
 
 
 
 
(5) white radish: the most suitable light quality for growth: the ratio of red and blue light is 8:1.
 
 
 
 
(6) wheaten vegetable: the ratio of red to blue light is 9:1, which is good for the growth of wheaten vegetable.
 
 
 
 
(7) strawberry and tomato: red and blue light 9:1 is the most favorable for the growth of strawberry and tomato, and the fruit is full and nutritious.
 
 
 
 
(8) Holly: when the red and blue light are distributed in the proportion of 8:1, Holly has the best growth, strong and well-developed root system.
 
 
 
 
(9) sprout: the best ratio of red, green and blue light is 6:2:1.
 
 
 
 
(10) Calla: the ratio of 6:2 of red and blue light is the best.
 
 
 
 
(11) red palm and scorching sun: according to the comprehensive analysis, the treatment of red and blue light 7:3 is better, which is beneficial to the form, root growth and dry matter accumulation.
 
 
 
 
(12) Dendrobium candidum: red blue light 7:3, its proliferation effect is the best; 6:4, it is more conducive to photosynthesis and material accumulation.
 
 
 
 
Taking lettuce as an example, the required planting environment parameters are:
 
 
 
 
Illumination above the plant: 2600-2900lx (pure red and blue spectrum illumination value, non white illumination value), no natural light, complete artificial lighting system, 6 h on and 2 h off in the early period, 3 cycles per day; 14 h on and 10 h off in the later period, 2 cycles per day;
 
 
 
 
Ambient temperature: 28-30 ℃ (air conditioner will be added later and maintained at 28 ℃)
 
 
 
 
Relative humidity: 50% - 70% (the air conditioning will be turned on to about 60% later)
