Abstract

The invention discloses an UV-resistant plant light supplementing source which comprises a light guide plate, a supporting grid plate, lens structures and artificial light sources, wherein the artificial light sources are mounted on the two sides of the light guide plate; the supporting grid plate is mounted below the light guide plate; a lens structure is mounted at the lower inner end of any one grid of the supporting grid plate; the light guide plate, the supporting grid plate and the lens structures are integrally made of a substrate material; a light conversion material is uniformly distributed in the substrate material. The light guide plate, the supporting grid plate and the lens structures integrally made of the substrate material can convert the artificial light sources and sunshine into light with the wave length beneficial to plant growth, and the light is uniformly irradiated on the plant so as to promote plant growth.

Description

technical field [0001] The invention belongs to the field of semiconductor lighting, and in particular relates to an anti-ultraviolet plant supplementary light source. Background technique [0002] At present, people use agricultural greenhouses and greenhouses to control the growth conditions to obtain products with high quality and high yield. With the continuous promotion of semiconductor plant lighting, according to the light requirements of different growth stages of plants, semiconductor devices used for plant lighting can significantly shorten the plant growth cycle and increase the corresponding crop yield. However, most semiconductor plant lighting devices cannot achieve the uniformity of light distribution, so that the plants in some areas do not receive sufficient light and grow thin and tall. Contents of the invention [0003] In view of the deficiencies of the prior art, the object of the present invention is to provide an anti-ultraviolet plant supplementary...
