Abstract
Solid−state lighting technology based on LEDs offers ample opportunities in plant lighting. This article presents a prototype of a solid−state lamp based on InGaN LEDs with radiation peaks of 440, 460, 530 and AlInGaP with radiation peaks at 590, 630 and 660 nm, equipped with a source of stabilized current and an optimized radiator. The emission spectrum of the LED illuminator is the result of numerical simulation using an experimentally obtained absorption spectrum of a leaf of a plant. The effect of using LEDs was compared to the effect of a sodium tubular lamp. Evaluation of the results of biometric measurements that were made throughout the experiment showed the possibility of the effect of the spectrum of the proposed LED illuminator on plant growth.
