Multispectral implementation method and device

Abstract

The invention provides a multispectral implementation method and device. The multispectral implementation method comprises the steps that S1, at least one mother lamp and at least one child lamp are arranged and all are provided with light sources, and mutually independent control lamps are arranged between the mother lamps and the child lamps; S2, the position parameters between the mother lampsand the child lamps are set according to the preset the width W target of an illuminating target area on the light receiving surface, and the width W overlap of the overlapped illuminating area of themother lamps and the child lamps on the light receiving surface is greater than or equal to the width W target of the illuminating target area; and S3, the on-off and / or light intensity of the motherlamps and the child lamps are / is independently controlled, more than two spectrums are achieved, and some special requirements for photo-biological regulation are met. Meanwhile, the mutually independent control lamps are arranged between the mother lamps and the child lamps and are controlled by different power sources, so that a control circuit is simple and low in cost, the main demand spectrums provided by the mother lamps are not affected, and the multispectral implementation method and device are high in utilization rate and very high in use flexibility.

Description

technical field [0001] The invention relates to a method for realizing multi-spectrum. [0002] The present invention also relates to a multi-spectrum realization device for realizing the above-mentioned multi-spectrum realization method. Background technique [0003] Plant growth lighting equipment, as the name suggests, is the lighting equipment (or lamps) used by plants. It simulates the principle that plants need sunlight for photosynthesis, supplements light for plants or completely replaces sunlight. At present, with the development of photobiological regulation technology, the method of lighting for plant growth is no longer single. Different plants, or the same plant at different growth stages, can adopt different control measures and use different spectral irradiation. For example, in the later stage of plant growth, for plants that harvest flowers or fruits, photobiology research usually requires the application of infrared or ultraviolet light for short-term indu...

Problems solved by technology

However, for some special bands, the total illuminance of the radiation is low and the use time is short. If such spectral requirements are integrated with the main demand spectrum in the entire growth cycle in the same plant growth lighting equipment, the performance requirements of the plant growth lighting equipment Very high, the control circuit is complex, the overall cost of the equipment is high, and the usage rate of special bands is low, especially for users with research needs.
