From the above plant and spectral data, the influence of each wavelength of light on plant photosynthesis is different, among the light required by plants for photosynthesis, 400 ~ 520nm (blue) light, and 610 ~ 720nm (red) contribute the most to photosynthesis, while 520 ~ 610nm (green) light, the efficacy rate of plants to exercise growth is very low. Led Light Grow Bar, Led Grow Light 600W , Induction Grow Light , Led Chip For Grow Light ,Full Spectrum Grow Light . In terms of illumination, LED lighting can guide the space, create a pleasing lighting environment, convey the value information of the space, and render the space with light. In terms of color temperature, the cooling and warm feeling of the lighting effect formed by the light source of different color temperature of the LED complements the difference in climatic conditions, and the designer makes the indoor space full and enjoyable through the grasp of the color temperature of the light. In terms of light efficiency, LED lighting can reduce energy consumption (high light efficiency). In addition, LED lighting also does not produce infrared radiation and ultraviolet rays, low temperature, long life, energy saving and other advantages, since this is the case, then why LED lighting is not the darling of indoor lighting? What are its disadvantages? The product will supply to all over the world, such as Europe, America, Australia,Seattle, Lithuania,Armenia, California.However, Taiwan is narrow and densely populated, with limited development space, but the Chinese mainland market with vast land and resources is the target of various businesses. The Chinese government recently issued the Twelfth Five-Year Plan 863 Plan, although the total funding is only about 46.11 million yuan (about 217 million yuan in new Taiwan), but the plan for the first time intelligent plant factory production technology research into the research project, the 7 projects discussed, including the application of LED energy-saving light sources in plant factories, showing that China's LED lighting application in plant factories is preparing to rise.
