Plant growth lamp

Abstract

The invention provides a plant-growing lamp which can effectively help plant to grow, blossom and bear fruits. The lamp consists of a filament (3), a lamp cap (1) and a lighting tube (4), and is characterized in that a fluorescent powder (2) is sprayed on the inner wall of the lighting tube; the fluorescent powder is a fluorescent powder which can emit a red light with long-wave band (640nm-750nm); or the fluorescent powder is a mixture of the fluorescent with a fluorescent powder which can emit a bluish violet light. The emission band spectrum is mainly positioned in the bluish violet region of 400-470nm and in the red orange region of 640-750nm. The repeatability of the emission band spectrum and a plant absorption spectrum is very good, thereby effectively helping the plants to grow, blossom and bear fruits.

Description

technical field [0001] The invention belongs to the fields of illumination and botany, and relates to a plant growth lamp, which can emit long-wave red light (640-750nm) or mixed light of red light and blue-violet light (400-470nm). The plant growth lamp can effectively promote plant growth and later flowering and fruiting. Background technique [0002] In recent years, under the strong advocacy and support of the state, my country's green and efficient agriculture has developed rapidly. Various greenhouses have sprung up, but due to seasons (such as winter and spring) and weather (such as cloudy and rainy days), the light in the greenhouses cannot fully meet the growth needs of plants, which seriously affects the growth and development of various crops. And blossom and bear fruit. Therefore, using artificial light sources to directly supplement light to crops in the greenhouse is an effective way to promote plant growth, and the theoretical basis for supplementing light t...

AI Technical Summary

Problems solved by technology

However, there is very little research in this field in China

The vast majority of greenhouses have low lighting efficiency or even no supplementary light measures. Among the supplementary light measures that have been taken, most of them use incandescent lamps, fluorescent lamps, high-pressure sodium lamps, high-pressure mercury lamps, etc. as light sources, and these light sources have large The disadvantages are firstly high energy consumption and low energy conversion rate; secondly, the blue-violet light and red light content required by plants in these light sources are very low, so they are not suitable for plant growth light sources.
