The present invention relates to a plant cultivation lighting unit, and more particularly to a plant cultivation lighting unit for cultivating plants using LED lighting and an illumination device having the same.

In recent years, as society develops and population increases, consumption has increased greatly. However, in accordance with changes in various environments, the cultivation of open land such as vegetables and fruits is becoming more and more difficult, and in spite of such environmental changes, plant factories and the like have recently attracted attention for stable supply.

However, in the case of plant factories, they are not widely applied because of the high cost of equipment and operation. In particular, one of the important factors in terms of equipment costs, operating costs, such as lighting, the domestic plant factory is using a fluorescent lamp without using expensive LED.

For example, it can be set to three or more modes, it can be configured to include a plurality of switch lever to select any one of the supply current 300mA, 500mA, 700mA. By providing the dip switch 144 as described above, it is possible to independently control each lighting unit 100 to output light of the wavelength material that is optimal to grow in response to various kinds of plants. In other words, there is an advantage that can provide the best growth environment customized by plant type.

The controller 150 controls the on / off operation of the power LED 120 based on the switching operation signals of the first to second switches 141 and 142, and controls the switching operation signal of the third switch 143. On / off operation of the UV LED 130 is controlled based on.

In addition, the controller 150 controls the output value of the power LED 120, that is, the current value supplied to the power LED 120 so that the wavelength band of the illumination light is adjusted according to the switching operation of the dip switch 144. Therefore, for each lighting unit 100, it is possible to independently control the voltage, current, and flicker.

According to the lighting unit 100 having the above configuration, the power LED 120 and the UV LED 130 can be controlled on and off for each lighting unit 100, and the output value of the power LED 120 can be controlled independently. By controlling the flicker, the electricity can be efficiently used.

The connector 200 connects the lighting units 100 in series, and each of the lighting units 100, that is, the first and second connectors 210 and 220 are connected to both ends of the lighting bar 110, respectively. Has a configuration connected by As described above, since the first and second connection parts 210 and 220 are provided at both ends of each lighting unit 100 in a structure capable of mutually coupling and separating each other in a female and water channel shape, the plurality of lighting units 100 are arranged in series. It becomes possible.

The power conditioner 300 is installed to supply power to the plurality of lighting units 100 connected in series. The power conditioner 300 is not provided for each lighting unit 100, but can be used by connecting a plurality of lighting units 100 connected in series, for example up to eight, there is an advantage that can reduce the installation cost have.

Plant cultivation lighting apparatus according to an embodiment of the present invention having the above configuration, by installing the lighting unit 100 installed in series by pairing the power LED 120 and UV LED 130, plant cultivation bed Corresponding to (10) it is possible to arrange and install the lighting unit 100, respectively. By outputting the red light and the blue light from each of the power LEDs 120 and the UV LEDs 130, the installation area can be reduced, and each lighting unit 100 can independently control the on / off of the LEDs. By installing the third to third switches (141, 142, 143) and the dip switch 144, the lighting unit 100 of the position not to cultivate the light is turned off, the plant is located in the upper part of the plant cultivation bed (10) By only driving the lighting unit 100, it is possible to reduce unnecessary power consumption, there is an advantage that can extend the life of the installation.

In addition, since the illumination light wavelength can be controlled differently according to the type of the plant using the dip switch 144, it is possible to effectively grow the plant by providing the optimal illumination light in consideration of the plant characteristics.

In particular, in the case of the present invention by using the UV LED 130, there is an advantage that can increase the plant's immunity compared to the general LED lighting, as well as to promote the growth of the plant to maximize the plant cultivation effect.
