Supplementary lighting device

Abstract

The invention discloses a supplementary lighting device. The device is characterized by comprising a rectangular bracket, the bracket comprises two beams and a plurality of longitudinal beams, and illuminant units are arranged on illuminant unit installation sites of the longitudinal beams; four corners of the bracket are provided with fixing pieces used for fixing the bracket to the inside of anillumination incubator. The device can be conveniently fixed to the inside of the illumination incubator, own power sources of the illumination incubator can be utilized to supply power, according tolight requirements of plants, the number of the illuminant units and layout modes can be arranged, the distance between the bracket and the plants can be adjusted, suitable illumination is ensured, and the use is flexible and convenient; the supplementary lighting device is added in the illumination incubator so that the existing illumination incubator can satisfy different experiment requirements, new equipment purchasing is reduced, and the fund is saved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation equipment, in particular to a light supplementing device. Background technique [0002] Plant growth has strict special requirements on light length and light intensity. The length of light refers to the length of light time in a day. The main influence on the growth of vegetables is the differentiation of flower buds, bolting and flowering, and fruiting. It also affects the formation of tubers, roots, and bulbs. Both the current light incubator and the artificial climate box can be set with different light time to meet the needs of different plants for the length of sunshine. However, another key factor closely related to the healthy growth of plants—light intensity—is often difficult to meet the needs of plant growth. According to the relationship between plants and light intensity, plants are divided into three ecological types: positive plants, negative plants and shade-tolerant pl...

AI Technical Summary

Problems solved by technology

The maximum light intensity of ordinary light incubators often still cannot meet the needs of plant growth. The distance from the saturated light intensity of plants (saturated light intensity: within a certain light intensity range, the photosynthetic rate of plants increases with the increase of light intensity. When the light intensity rises to After a certain value, the illuminance value when the photosynthetic rate does not continue to increase) has a large difference

The experimental plant materials grown in the incubator are often weak in growth and prone to excessive growth and disease

Affected the results of the test and the progress of the test

For the old-fashioned fluorescent tube or LED light incubator, it is difficult to achieve flexible supplementary light that exceeds the set light intensity of the incubator
