First of all, we must know that if each cannabis grow is exposed to the same light, the illumination of the LED grow light must be uniform. The uniformity of LED cannabis grow light illumination can be divided into the uniformity of chip distribution, the installation height and the distance distribution between the LED grow lights.

LED grow light chip distribution

The chip distribution is based on the LED grow light fill light cannabis grow characteristics. After the lamp bead ratio is obtained, how to intersect between the chips is calculated, and finally distributed on the grow light package and COB panel according to a certain rule, so that each LED The light quality and intensity of the cannabis grow are evenly distributed in the main area.

Installation height and distance distribution of LED grow lights

The arrangement of the spacing between each LED grow light is mainly determined according to the light intensity. In addition, the installation height of the LED cannabis grow light must be considered. After a comprehensive calculation, the distance distribution between the LED grow lights can be obtained to ensure large-area cannabis cultivation. Uniformity of illumination.

LED grow light lamp bead distribution

The uniform distribution of LED grow lamp beads is to ensure that the light energy is evenly irradiated on the hemp. 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 state of cannabis in the irradiation area of the LED grow lamp will be different, and the meaning of using the LED grow lamp will be lost.

How to control the distribution of lamp beads in LED grow lights? First determine the number of LED grow lamp beads, and then determine the ratio of red and blue lamp beads according to the demand for cannabis, and then install them on the lamps evenly in a dislocation. 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 cannabis grow lights can be superimposed to achieve the desired effect.

Physical reaction with optical equipment

The LED grow lamp 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.

LED hemp grow light uses light reflection and refraction not only to make the light more uniform, but also to achieve high luminous efficiency. It mainly uses reflectors and metal substrates used in COB. The principle of LED grow light reflectors reflects the light emitted by the light source into a beam, increasing Local light intensity, the reflective effect of the metal substrate is also to maximize the light energy emitted by the LED grow lamp 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, which change the propagation trajectory of light. Generally, single lenses and retest lenses are used, which can control the light distribution very accurately.

Therefore, the uniformity of LED grow lighting is simply: to make the light quality and light intensity distribution around the cannabis grow uniform, as well as the light quality and light intensity distribution at the intersection between adjacent lights and other illuminated areas.
