LED grow lights are lights used to illuminate growing grows. grow growers hope that their grows can grow better. The purpose is to give grows growth to achieve the ideal state of light, and efficiently and evenly condense the light on each grow. on. How to realize the LED grow light to efficiently and uniformly illuminate the grows?
1. Distribution of LED grow lights
The uniform distribution of LED grow light beads is to ensure that the light energy is evenly irradiated on the grows. The lamp beads are mainly composed of red and blue lamp beads. If the positions of the lamp beads of different spectrums are not reasonably and evenly distributed, the growth status of the grows in the irradiation area of the LED grow light will be different, and the meaning of using the LED grow light will be lost.
How to control the distribution of lamp beads in the LED grow light? First determine the number of LED grow light beads, and then determine the ratio of red and blue lamp beads according to the needs of growing grows, and then install them on the lamps evenly. If it is a small area of light supplementation, it can ensure uniform light in the middle, if it is a large area of light supplementation, ensure that the surrounding light is even, so that the adjacent LED grow light illumination can be superimposed, just to achieve the desired effect.
2. The physical reaction of optical equipment
The LED grow light can also realize the efficient use of light under the condition of uniform illumination. The main physical principles used are light reflection and light refraction.
The LED grow light uses the reflection and refraction of light to not only make the light more uniform, but also achieve high luminous efficiency. It mainly uses the reflector and the metal substrate used by the COB. The principle of the LED grow light reflector reflects the light emitted by the light source into a beam of light. Increase the local light intensity, the reflective effect of the metal substrate is also to maximize the light energy emitted by the LED grow light beads to be used by grows, the reflected part is auxiliary light, it also has the role of fixing the lamp beads and heat dissipation.
The principle of light refraction of LED grow lights is mainly to use optical lenses. The principle changes the propagation trajectory of light. Generally, single lens and retest lens are used, which can control the light distribution very accurately.
The advantages of LED grow lights over traditional grow lights are more efficient and even in terms of light, and they also have advantages in terms of volume, dimming, and less heat.
How long is the appropriate lighting time for LED grow lights?
How long is the lighting time of LED grow lights? In other words, how long does it take to add light to grows? Can you fill in the light 24 hours a day without interruption? Sometimes customers and manufacturers are more confused. In fact, these questions can be answered like this:
How long is the lighting time for LED grow lights?
1. Determined according to the degree of lightloving of the grow
Not to mention that LED grow lights do not rest, almost all living things need to rest, so it is impossible to use LED grow lights to fill the grows with light, which will have a bad effect on the grows. Studies and experiments have proved that the best time for grows to add light is controlled at about 12 hours, and it is necessary to leave enough time for grows to rest for 4-6 hours.
For light-loving grows, it is necessary to use LED grow lights to supplement light for grows at 6:00-10:00 and 17:00-00:00, because 10:00--17:00 is the sunlight that meets their growth needs Time period, so it takes about 11 hours for grows to fill in light.
For grows that do not like light, their growth needs can be met when there is sunlight. The time for supplementing light with LED grow lights only needs to be set according to the local sunrise and sunset time, and the supplementary light time should avoid grow rest time as much as possible.
2. Set according to the growing environment
The growing environment mentioned here includes the difference between the north and the south, the difference between spring, summer, autumn and winter, and the difference between indoor and outdoor sunlight. Regional and seasonal differences can be set according to the light law, the closer to the equator, the stronger it is to set the lighting time with LED grow lights. Strong in summer and weak in winter, set the lighting time with LED grow lights according to local conditions. There is a big difference in the light that can be received for indoor and outdoor growing. It takes 16-18 hours to fill up the light with LED grow lights for the whole time. Outdoor grows use LED grow lights to fill up the light according to the difference in the illuminance of sunlight.
No matter what grow you grow, you must first understand the light required for growing, and then use LED grow lights to supplement and dim light according to the growing environment to give grows better light and growth status.
