Document Type and Number:
WIPO Patent Application WO/2011/121845
Kind Code:
A1
Abstract:
Disclosed is an illumination apparatus (12) for irradiating light onto plants. The illumination apparatus (12) is provided with light-emitting diodes (23) as light sources; an LED substrate (22) that has the light-emitting diodes (23) arranged thereon, side by side; lenses (25) (optical member) that are formed between the LED substrate (22) and the plant to be subjected to irradiation, and that change the paths of light irradiated from the light-emitting diodes (23); and a lens holding plate (24) (optical member) for holding the lenses (25) in place. The lenses (25) are mounted onto the apparatus in an attachable/detachable state. Thus, an illumination apparatus for plant cultivation, wherein improvements were made from a perspective of heat-generation control and light distribution adjustment of the LEDs, is provided.
