The present invention embodies a technology which adjusts, at low cost, a quantity of light, according to a wavelength range of light irradiated from a lighting device, to be suitable for a growth condition of a plant. To this end, the present invention lowers the production cost of a lighting device for a plant factory by adopting a low-priced LED blue chip instead of a costly LED red chip which has been conventionally adopted in a plant factory； and allows a quantity of light, corresponding to a target condition in a wavelength range that is suitable for the target condition of plant growth, to be irradiated from a lighting device, produced by means of combining red series, green series and yellow series phosphors with the LED blue chip. Further, the present invention suggests a technology which reduces eyestrain from a red light source, thereby improving working conditions, and at the same time, enhances the wavelength of light emitted from the lighting device, thereby being capable of relatively further increasing the growth efficiency of a plant.本發明涉及植物工廠用發光二極體照明模組和搭載該照明模組的植物工廠用發光二極體照明裝置，這是排除通常所採用的高價的發光二極體紅色晶片，採用發光二極體藍色晶片來降低植物工廠用照明裝置的製作成本，同時改善由照明裝置發出的光的波長，由此能夠更加相對地提高植物的繁育效率，使得從發光二極體照明模組和搭載上述發光二極體照明模組的發光二極體照明裝置發出的光在藍色系列波長範圍（450nm）中體現峰值，在紅色系列波長範圍（660nm）中也體現峰值，從而使植物的繁育全面促進的技術。根據本發明，以一個晶片體現藍色晶片光源和塗敷於該藍色晶片光源的外表面的紅綠黃螢光粉，因此具有製作方便的優點。
