Problems solved by technology

[0003] At present, the light in agricultural production cannot be well artificially controlled like fertilization and irrigation, and can only rely on natural light for lighting. However, the change of sunlight in different seasons, weather and regions is different, and the law of change is more complicated. Therefore, the situation that agricultural production depends on the weather is difficult to change
At present, the light sources in biological lighting are mainly incandescent lamps and high-intensity gas discharge lamps as simulated light sources, whose spectrum is difficult to adjust, and can only be used for some basic applications.
At present, there are still researches on the use of light-emitting diodes (LEDs) for biological lighting. At present, due to the reasons of LED technology itself, there are still great limitations in the selection of power and spectral line wavelengths.
Another big limitation is that the dynamic adjustment of the spectral output of the lighting source has great limitations.

Abstract

A lighting system for the biologic space is composed of the electromagnetic induction lamps, a lamp system for gathering the light of lamps in biologic space, a radiation sensor for obtaining the current information about optical spectrum and illuminance, a controller for dynamically controlling the illuminance and optical spectrum distribution, and a light source controlling circuit.

Description

technical field [0001] The invention relates to the field of automatic instruments and meters, and more specifically relates to an electromagnetic induction lamp bio-illumination system with spectrum adjustment function. Background technique [0002] Studies have shown that light plays an important role in living things. Since the middle of the last century, researchers began to study the influence of light on the growth of living things. After long-term research, many achievements have been made. In terms of plant research, the catalyst mechanism of photosynthesis affected by light (such as Making light work of enzyme catalysis: protochlorophyllide oxidoreductase, TRENDS INBIOCHEMICAL SCIENCES 30 (11): 642-649 NOV.2005), light can also change the growth cycle of plants (such as Conserved Expression Profiles of CircadianClock-Related Genes in Two Lemna Species Showing Long-Day- and Short-Day Photoperiodic Flowering Responses, Plant Cell Physiol.
