INSTRUMENT FOR PUTTING ILLUMINATING LIGHT WAVELENGTH UNDER CONTROL

摘要

PROBLEM TO BE SOLVED: To provide an instrument for putting illuminating light wavelengths under control, to be used in an aquarium to inhibit algae (moss) to be deposited on the wall surface of the aquarium, through utilizing photosynthetic activity.;SOLUTION: The instrument for putting illuminating light wavelengths under control is provided, which is to be used in an aquarium, in an L-shapedly fixed manner; the instrument being made by molding processing of such a low-expanded green polyethylene plate or green acrylic plate that illuminating light transmitted through a colored plate installed on the aquarium constitutes a hindrance to growing algae on the wall surface of the aquarium with the colored plate, using the illuminating light emitted from the fluorescent lamp of an illuminator for the aquarium. In the instrument, the L-shaped fixing is made in such a way that one side of the plastic plate is on the front surface of the aquarium, the other side being furnished with a plate for putting illuminating light wavelengths under control. By illuminating the plate for putting illuminating light wavelengths under control with light from the fluorescent lamp to be transmitted through the plate, algae growth on the surface of the aquarium is inhibited thanks to the illuminating light reaching both of the front surface and the bottom of the aquarium.;COPYRIGHT: (C)2012,JPO&INPIT
