Embodiment Construction

[0018] Such as figure 1 As shown: (2) light boards surround both sides of (1) reaction tank, (3) fans are installed on both sides and above of (4) stainless steel light source cabinet, facing the two light boards and the top of the culture tank.

[0019] (5) red light, (6) blue light, (7) green light are arranged on the light board as follows figure 2 As shown, it is arranged in six rows. The light quality of the light source is composed of 80% LED red light + 15% LED blue light + 5% green light. Each light board has 48 red lights, 9 blue lights, and 3 green lights.

[0020] At the initial stage of cultivation when the concentration of algae is low, install the light board at a light intensity of 3mW / cm 2 The 1st gear position can avoid the photoinhibition of microalgae caused by too high light intensity. When the absorbance of the algae liquid is higher than 0.5, install the light board at a light intensity of 4mW / cm 2 The 2nd gear position provides sufficient light. Wh...

Abstract

The invention discloses a space microalgae lighting system, which includes a circuit system, an LED lamp panel assembly, and a light source cabinet. The system aims at the energy saving high efficiency characteristic of microalgae culture in a space environment condition, an airlift tank-type photobioreactor and a space microalgae lighting system are established, and the rule that the lighting intensity, light quality combination and lighting period affect microalgae culture is explored. The light source demand and lighting method of space microalgae culture are established, and a good solution is provided for microalgae culture and improvement of circulation closure of system substances in a controlled ecological life support system in a space environment in our country.

Description

technical field [0001] The invention relates to a lighting system for space microalgae, which is applied to the field of rapid cultivation and research of small-scale microalgae in environments such as manned spaceflight. technical background [0002] Long-term, long-distance, and multi-crew manned space flight, deep space exploration, and planetary settlement must rely on the Controlled Ecological Life Support System (CELSS) that can achieve a closed material cycle to provide long-term food and other life protection materials. Microalgae have the characteristics of high photosynthetic efficiency, rapid growth, high nutritional value, and rich in antioxidants. They can be used as biological components of CELSS to play an important supplementary and emergency role in the regulation of atmospheric balance and stable food supply. Therefore, how to achieve efficient cultivation of microalgae is the basis for the establishment of aerospace microalgae biological components, combin...
