摘要

PURPOSE: A device for measuring and analyzing the photosynthetic photon flux distribution and illumination efficiency of an artificial lighting source for plant growth is provided to easily analyze the photon flux distribution by measuring the photon fluxes per each position within a light irradiation range of the artificial lighting source as a transfer unit is moved by a transfer motor, and a photon sensor mounted in the transfer unit is rotated around a lighting unit and horizontally moved.;CONSTITUTION: A device for measuring and analyzing the photosynthetic photon flux distribution and illumination efficiency of an artificial lighting source (101) for plant growth includes a body (100), a photon sensor (200), a rotating unit (300), a transfer unit (500), a control unit, and a computer. The artificial lighting source emitting light from the top to the bottom is mounted on the body. The photon sensor senses the light emitted from the artificial lighting source. The upper part of the rotating unit is joined to the body, and the lower part of the rotating unit is rotated around the artificial lighting source. The transfer unit is joined to the lower part of the rotating unit to be movable, and the photon sensor is mounted on the transfer unit. The transfer unit transfers the photon sensor in a direction vertical to a rotating direction of the rotating unit. The control unit operates the rotating unit and the transfer unit. The computer receives the property information of the light sensed by the photon sensor, thereby analyzing the photon flux distribution and lighting efficiency of the lightning unit.;COPYRIGHT KIPO 2013
