Description
Technical field
The present invention relates to a kind of plant growth lamp.
Background technology
The growth needs sun of plant, has grasped after the inner principle that plant needs the sun from people, and modern science can allow plant not have the place of the sun better to grow.Chlorophyll in blade is realized photosynthesis by main blue light (380nm-480nm) and the ruddiness (600nm-700nm) absorbing in the sun, people can by light filling technology or completely artificial light technology can allow equally plant complete photosynthesis.
At present, artificial light source for plant culture mainly contains fluorescence lamp & lantern and LED lamp two classes, fluorescence lamp & lantern plant growth light source is generally that the fluorescent material that can launch the required specific band light source of plant growth (blue light and ruddiness) is coated on lamp wall, then sends corresponding light wave by ultraviolet ray excited fluorescent material; LED lamp & lantern plant growth light source is generally directly to send by blue light and red LED chip the corresponding light wave that plant growth needs.Above product has a common ground, after being product export, its optical property of the product of same model is fixed, after that is to say that product is produced, the blue light that it sends and the amount of ruddiness and ratio are constant, and plant is not identical to the demand of light in each production phase, therefore for adapting to the demand of the different growth phases of plant, peasant household just need to buy the growth light source of different model, and its cost is high; And, growth light source is needed to integral replacing, change inconvenience, workload is large, and this is also uneconomical.In addition, its fluorescent material of fluorescence lamp & lantern plant growth light source (especially red fluorescence powder) in conventional art from excitaton source excessively close to, must select the good fluorescent material of stability to prevent hot quenching effect, make the selection of red fluorescence powder narrow, and hot-quenching its optical property of high fluorescent material of going out is not necessarily optimum, therefore also limited the optical property of plant growth light source product.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of plant growth lamp, it has well met user's adjusting to plant growth lamp optical property according to the different growth phases of plant, and has solved the impact that fluorescent material hot-quenching is gone out, and has widened the alternative of fluorescent material.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of plant growth lamp, comprise lamp socket, the lampshade of bowl type is installed on described lamp socket, bowl position, the end at lampshade is provided with the light source that can send 380nm ~ 480nm blue light, in the rim of a bowl position of described lampshade, be provided with the Transparent lamp shade sheet of capping the rim of a bowl, described Transparent lamp shade sheet and described light source have interval apart, be provided with and can be subject to the blue-light excited red fluorescence powder that sends 600 ~ 700nm ruddiness of 380nm ~ 480nm on this Transparent lamp shade sheet, and described Transparent lamp shade sheet removably connects and is arranged on described lampshade.
As the improvement of technique scheme, described Transparent lamp shade sheet is glass, lucite, transparent plastic or film.
Further improvement as technique scheme, described light source is ultraviolet lamp, on described lampshade, between described light source and Transparent lamp shade sheet, be provided with the second Transparent lamp shade sheet, described the second Transparent lamp shade sheet is provided with and can be subject to the ultraviolet ray excited blue light fluorescent powder that sends 380 ~ 480nm blue light, and the second Transparent lamp shade sheet is detachably connected on described lampshade.
Further, described light source is Non-polarized lamp, is coated with the blue colour fluorescent powder that can send 380 ~ 480nm blue light described in this on Non-polarized lamp inwall.
Further, described light source is LED blue chip.
Further, described red fluorescence powder is (Sr, Ca) AlSiN
