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-pressur...

Embodiment 1

[0019] Embodiment 1: According to chemical formula Li x AlO 2 : Fe 3+ y , where 0.5≤x≤1.1, 0.001≤y≤0.01, according to the following metering ratios A (x=0.5, y=0.003), B (x=0.5, y=0.007), C (x=1, y=0.005) D (x=1, y=0.008), weigh raw material A (18.5gLi 2 CO 3 , 51gAl 2 o 3 , 1.212gFe(NO 3 ) 3 9H 2 O), B (18.5gLi 2 CO 3 , 51gAl 2 o 3 , 2.828gFe(NO 3 ) 3 9H 2 O), C (37gLi 2 CO 3 , 51gAl 2 o 3 , 2.02gFe(NO 3 ) 3 9H 2 O), D (37gLi 2 CO 3 , 51gAl 2 o 3 , 3.232gFe(NO 3 ) 3 9H 2 O), respectively add A (210g agate ball, 110g deionized water), B (220g agate ball, 110g deionized water), C (270g agate ball, 140g deionized water), D (280g agate ball, 140g deionized water) for ball milling, and the ball milling time is uniformly 5 hours, then take out the wet material and put it in an oven for drying. According to the difference in water content of each sample, the drying time varies from 20 to 30 hours. After taking out the dried materials, add boric acid A ...

Embodiment 2

[0020] Embodiment 2: select 10g of phosphor powder A prepared in Example 1, add 3ml of butyl acetate and 1ml of nitrocellulose and mix evenly, then evenly apply it to the inner wall of the glass tube, and after drying, make the filament , the lamp holder (starter, rectifier), and the lamp tube are assembled together, so that the plant growth lamp with the spectrum in the deep red region of 640nm-750nm is obtained.

Embodiment 3

[0021] Embodiment 3: select B part phosphor powder 6g prepared in embodiment 1, add 4g BaMg again 2 al 16 o 27 :Eu 2+ Add 3ml of butyl acetate and 1ml of nitrocellulose, mix evenly and apply it on the inner wall of the lamp tube. After drying the lamp tube, the filament, lamp holder (starter, rectifier), and straight tube lamp Assembled together, the plant growth lights with spectra in the 400-500nm and 640nm-750nm blue-violet and deep red regions are obtained.

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...
