植物育成用照明装置並びに植物水耕栽培装置および植物水耕栽培方法
Document Type and Number:
Japanese Patent JP6484083
Kind Code:
B2
Abstract:
Disclosed are a plant growth lighting apparatus capable of forming a lighting region having a high degree of illuminance uniformity in the array direction of a light-emitting element array as well as a plant hydroponic cultivation apparatus and a plant hydroponic cultivation method capable of growing a plant with high growth efficiency even in a large cultivation region. A plurality of light-emitting element units, each including a first light-emitting element and a second light-emitting element having an emission peak wavelength different from that of the first light-emitting element, are arranged side by side along one direction to form a light-emitting element array. The light-emitting element unit is constituted by two second light-emitting elements disposed so as to be spaced apart from each other in the one direction and one first light-emitting element disposed between the two second light-emitting elements. A distance between first light-emitting elements in light-emitting element units adjacent to each other and positioned in an end part of the light-emitting element array is shorter than a distance between first light-emitting elements in light-emitting element units adjacent to each other and positioned in a central part of the light-emitting element array. A distance between two second light-emitting elements in a light-emitting element unit positioned in the end part is shorter than a distance between two second light-emitting elements in a light-emitting element unit positioned in the central part.
