It is 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 design serve the chip, so the rationality of the light distribution of the LED plant light is almost completely Determined by the wafer.
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 designing and assembling LED plant lights. Strictly speaking, the ratio of chips used for different growth periods of different plants is different, but considering that it is impossible to change it every few days A batch of plant lights requires too much work and high cost. Therefore, according to whether the plant is grown mainly by using its rhizomes or by using its flowers and fruits, in general, red light chips are more than blue light chips. Plants with flowers and fruits are harvested. The ratio of red light chips can be increased appropriately.
The light distribution rationality of LED grow lights directly affects the growth status of plants. It is also a very important index that must be considered first in the design of LED grow lights, and it is also the most important parameter for judging the performance of LED grow lights.
