Application of LED PCBs in Plant Growth Lights
With the advancement of smart agriculture, plant growth lights have gradually become essential equipment in greenhouses and plant factories. As the key carrier of the light source, the performance of LED PCBs directly determines the lighting efficiency, operational stability, and overall growth performance of plants , thus play ing a vital role in the field of agricultural lighting. 1. Efficient Heat Dissipation and Stable Spectrum Output During operation, LED chips continuously generate a large amount of heat. If the heat is not dissipated in time, thermal accumulation can lead not only to reduced luminous efficiency and shortened lifespan of the LEDs, but also to shifts in spectral wavelength. Plant photosynthesis is highly sensitive to specific wavelengths of light , such as red light (620 – 660 nm) and blue light (450 – 470 nm) , and even slight wavelength deviations can directly affect ph...
