Description
Technical field
The present invention relates to a kind of plant lamps for turning photoreactivation translucent cover and its application.
Background technique
In recent years, plant factor due to be able to achieve crop high-efficiency and continuous growth, without rest plantation the characteristics of and attract attention.
Wherein, the illumination system for belonging to one of key technology is more taken seriously.Initially, plant lamp is generally fluorescent lamp or high-pressure sodium
Lamp, light quality is fixed to hinder plant factor's development with the shortcomings that energy consumption high photosynthetic efficiency bottom within a very long time.With luminous
The invention of diode (LED) and be applied to plant lamp in, the illumination system of plant factor has obtained biggish promotion.Due to plant
The light that needs of photosynthesis focus primarily upon blue light and feux rouges, LED plant lamp can be adjusted according to the needs it is blue feux rouges ratio,
The spectrum of the two is set more to coincide, to play the effect for promoting plant growth.LED plant lamp can be divided into following two class
Type: 1) blue-ray LED and red-light LED are combined；2) UV/blue LED and phosphor combination type.Compared to the former, Hou Zheyou
Preparation is simple, and advantage at low cost is popularized in plant factor.However, in UV/blue LED and phosphor combination
In type plant light source, the ingredient for regulating and controlling light needs to change the ratio between different fluorescent powders, for actual use bring it is many not
Just.
On the whole, it reduces to improve the efficiency of illumination system with cost, from LED plant light source and can mainly build
Mode two parts optimize.Firstly, light source part focuses primarily upon the research and development to the multicolor luminous fluorescent powder of single-matrix, reduce
Influence between a variety of fluorescent powders, but being used in the fluorescent powder encapsulated on chip all is that disposably, not can be recycled；Its
It is secondary, people also proposed it is various build mode to study the effect that do not share the same light to plant, but be easy to make in heuristic process
At the waste for building cost.
LED lamp currently on the market requires outfit translucent cover and plays the role of protecting lamp source and make to shine uniform.
Meanwhile YAG yellow fluorescent powder is mixed in translucent cover and is also had been reported as secondary light conversion.It can be seen that by light transmission
Cover, which carries out corresponding modification, can make LED realize new function, for example LED plant lamp.
