LED light source device for plant factory {Light Emitting Diode light source device for plant factory}

The present invention relates to an LED light source device for a plant factory, and more particularly, red, blue and white LEDs for inducing photosynthetic action of plants are arranged according to each ratio, LED for plant plants to provide light at a constant light source ratio It relates to a light source device.

In general, a plant factory requires a lighting device for inducing photosynthesis, a hydroponic cultivation device for supplying nutrients and water, an air conditioning device for constructing a plant growth environment, and a control device for automatically controlling each device.

Conventional lighting apparatuses for inducing photosynthesis of the plant include fluorescent lighting, incandescent lighting, and high pressure sodium lighting, and recently, lighting apparatuses using LEDs have been used.

Such a plant factory is actually a plant factory as shown in FIG.

Here, the conventional lighting device for plant plants using the LED is arranged to provide a light source suitable for photosynthesis by arranging red LED, blue LED and white LED at any ratio without providing a light source to the plant using a single color LED.

As shown in FIG. 1B, a lighting device for a plant factory using a conventional multi-color LED in which red LEDs 21, blue LEDs 22, and white LEDs 23 are arranged at arbitrary ratios has a 2-watt (W) red LED. (21), blue LED (22) and white LED (23) were arranged in a line on the PCB 10 of the size of 6 x 60 cm.
