LED lighting module for plant factory and LED lighting device

Abstract

The invention relates to an LED lighting module for a plant factory and an LED lighting device. 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, 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. So light emitted from the LED lighting module and the LED lighting device with the LED lighting module can reach to a primary peak in a wavelength range (450 nm) of blue light, and reach to a secondary peak in a wavelength range (660 nm) of red light, so as to promote plant growth as a whole. According to the LED lighting module for the plant factory and the LED lighting device, a blue chip light source and a phosphor composed of yellow, green, red phosphors coating at the surface of the blue chip light source are integrated in one chip, so production is easy.

Description

technical field [0001] The present invention relates to a technology that eliminates the expensive red chips of light-emitting diodes commonly used in plant factories and replaces them with blue chips of light-emitting diodes, thereby reducing the production unit price of lighting devices for plant factories and reducing the visual acuity caused by red light sources. Fatigue, while improving the working environment, improve the wavelength of light emitted from the lighting device, thereby relatively improving the growth efficiency of plants. [0002] In more detail, it relates to the technology of making the light emitted from the LED lighting module and the LED lighting device equipped with the LED lighting module achieve a primary peak in the blue series wavelength range (450nm), and achieve a primary peak in the red series wavelength range (450nm). The wavelength range (660nm) achieves a secondary peak, thereby promoting the growth of plants in general. Background techniq...

Problems solved by technology

[0006] In the past, there was also a method of using three-wavelength fluorescent lamps, which had the problems of excessive power consumption and short life, but it was not suitable for plant growth.
