| Abstract: | Based on the photosynthesis and photomorphogenesis of greenhouse plant, two kinds of light emitting diode (LED) arrays for plant illumination were designed. The irradiance superposition formula of the LED array was derived, and then the LED arrays were simulated according to the formula. The red and blue LEDs were uniformly arranged, the proportion of red LEDs to blue LEDs is 1∶1 in the first array, and the proportion of red LEDs to blue LEDs is 4∶1 in the second array. Experimental results analyzed by TracePro software show that the second LED array has an advantage over the first one on irradiance uniformity, and the second LED array perform better at cooling because the spacing between LEDs become larger. The LED arrays distributions applied to plant illumination were achieved and reliable reference for the design of LED array is provided. |
