Sunlight room with selective transmission photovoltaic film for plant light supplementing

Abstract

The invention discloses a sunlight room with a selective transmission photovoltaic film for plant light supplementing. The sunlight room comprises a south wall, a north wall, sloped beams, glass, the selective transmission photovoltaic film, plant light supplementing lamps, a storage battery and a control box. The south wall is connected with the north wall through the sloped beams at the top; the glass is the roof of the sunlight room, and is supported and fixed through the sloped beams; the glass is covered with the selective transmission photovoltaic film, and the plant light supplementing lamps are located below the sloped beams and fixed on the sloped beams. By means of the sunlight room, it is achieved that under the condition that additional energy does not exist, solar energy is completely converted into sunlight required by plants, sunlight is supplied to plants in a reasonable mode, the structure is simple and compact, the cost is low, and the popularization potential is large.

Description

technical field [0001] The invention relates to a sun room, in particular to a sun room which utilizes a selective transmission photovoltaic film to supplement light for plants, and belongs to the technical field of solar energy utilization. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. Solar water heaters have been successfully commercialized, and how to use solar energy more effectively has become the content of research by scientists from all over the world. [0003] A greenhouse is a facility that can transmit light and keep warm, and is mostly used to grow plants. In seasons that are not suitable for plant growth, the greenhouse can increase the growth period of plants and increase production. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low ...

AI Technical Summary

Problems solved by technology

[0005] However, the current sun room still cannot meet the needs of plant cultivation in many cases: some plants are planted in the north or other areas with insufficient sunlight, and the normal growth of the plants is affected due to insufficient lighting time and intensity; Due to the limitation of fertilization in organic planting, the growth cycle of plants must be affected, so supplementary light is needed to shorten the production cycle

The above problems can be made up for by adding supplementary lights, but plant supplementary lights need to consume a certain amount of electric energy, which increases the cost of planting

[0006] Using solar energy to provide power for plant fill lights can reduce plant planting costs by using renewable energy. However, photovoltaic cells currently used in agriculture are opaque. If they are installed on the surface of a sunny house, they will block the sunlight and affect the lighting of plants. , if it is set in other positions, it will reduce the effective planting area of ​​the land

Therefore, the use of solar energy for plant light supplementation has not been well promoted and applied.
