Description

{GREEN WALL EQUIPPED WITH LED PACKAGELIGHT FOR GREEN WALL}

The present invention relates to a green wall, and more particularly, to a green wall equipped with a lighting LED package for the green wall.

Recently, because modern people spend 80 to 90% of their time indoors in a limited way, Microbial contamination has a fatal adverse effect on the health of residents.

According to this trend, in the past, the construction industry mainly invested in exterior materials and landscaping of apartments, but now, the emphasis is on eco-friendly composition, comfort, and improvement of indoor air quality. The demand for the improvement of the eco-friendly quality of life for the internal residential environment rather than the residential environment is increasing.

In the current living environment, efforts are being made to create a more nature-friendly living environment by managing indoor air quality and creating an indoor landscaping. Accordingly, indoor gardens are being actively developed.

However, in indoor gardens, sunlight cannot be sufficiently irradiated indoors, so LED lights for plant cultivation are additionally installed to replace sunlight and irradiate light wavelengths of specific bands that affect plants. For example, in the case of blue light with a wavelength of 450 nm, growth is inhibited and flower bud formation is promoted. And in the case of red light with a wavelength of 660 nm, chlorophyll is produced by promoting the growth of leaves and stems and applied to photosynthesis. Therefore, LED lighting for plant growth is an essential element inducing plant growth, fruiting flowering, and the synthesis of functional substances by controlling it to replace sunlight that cannot be sufficiently irradiated to the indoor garden.

As shown in FIG. 2, the indoor plant cultivation apparatus using the LED light 3 for plant cultivation configured as described above is suitable for plant growth because pink color is expressed, but for interior use, it gives fatigue to the human eye and color rendering properties. (演色性; a phenomenon that affects the color of an object depending on the light source) is low, so it is difficult to understand the color and shape of the plant.

In addition, when the red light LED package (2) and the white light LED package (1) are crossed and used in series connection, one red light LED package (2) and one white light LED package (1) must be configured as one set for plant growth. Since it is possible to implement a target spectrum, there is a problem that requires a considerable volume and area.

In addition, the indoor cultivation method as shown in FIG. 2 has a problem in that the efficiency of space use is lowered in such a way that plants are horizontally arranged and cultivated.

In addition, if a horizontally arranged garden is arranged in different layers to grow many plants, it is difficult to maintain and energy use is a problem because LEDs corresponding to the horizontally distributed area must be built on each floor. there was.

It is preferable that the circulation housing unit 11 is arranged side by side on the lower side of the tray housing unit 13 so that the center of gravity faces downward to give a sense of stability.

The lighting module 50 includes a center rod 51 , an LED rod 53 , and an LED package 55 . The center rod 51 extends perpendicularly to the upper end of the body frame 10 in the front direction. The LED rod 53 is coupled to the outer end of the center rod 51 perpendicular to the longitudinal direction of the center rod 51 . The LED package 55 will be described in detail below with reference to FIG. 6 .

As shown in Fig. 4, the center rod 51 has one end coupled to the upper end of the body frame 10 and a plate-shaped rod portion 51a extending vertically in the front direction of the main body prime 10 and the other end is bent downward. and a bent end portion 51b.
