Abstract

The present invention provides a lighting equipment for microalgae cultivation and a manufacturing method of the lighting equipment. The lighting equipment includes: a lighting equipment assembly and at least one LED lamp bead installed on the lighting equipment assembly. The lighting equipment has at least the following luminous characteristics : a) part or all of the spectrum with a wavelength between 500nm and 660nm is converted by excitation of fluorescent materials; b) the peak wavelength of the spectrum is between 400nm and 500nm, and its half-wave width of the spectrum is less than 50nm; c) the spectrum is between 500nm and There is a second peak between 660nm, and the absolute difference between the peak and valley of the relative spectrum is less than 0.25; d) In the spectrum of lighting equipment, the ratio of radiant energy between red light and blue light and the ratio of radiant energy between red light and green light between 0.5 and 1. The spectrum curve of the lighting equipment of the invention coincides with the absorption spectrum curve of the microalgae, has high light energy utilization efficiency, and can satisfy the absorption of different microalgae.

Description

technical field [0001] The invention belongs to the technical field of lighting devices, and in particular relates to a lighting device for cultivating microalgae and a manufacturing method of the lighting device. Background technique [0002] Microalgae are a kind of ancient lower single-celled plants, widely distributed in oceans, freshwater lakes and other waters. Microalgae have small cells, diverse shapes, strong adaptability and wide distribution. A wide variety of algae play an important role in the aquatic ecosystem. They are important natural bait for shellfish, shrimp and sea cucumber farming, and are the basis of the fish food chain. The natural bait for marine fish generally comes directly or indirectly from planktonic algae. Because unicellular algae are rich in nutrients, and have the characteristics of fast reproduction and high yield, the polysaccharides, proteins, pigments, etc. produced by cell metabolism are widely used in the pharmaceutical industry, foo...
