Description

A kind of method and device thereof of adjustable light sources combination

Technical field

The invention provides a kind of method and device thereof that changes combination of light sources, belong to especially plant growth regulating and electronic technology field.

Background technology

One of important envirment factor in the plant growth only.The advantages such as LED is little because of volume, quality is light, the life-span is long, light intensity is adjustable make one of its important light source that becomes the Plant Light environment conditioning, all have obvious advantage aspect energy-conservation and the Promoting plant growth.At present, LED has obtained certain application in Plant Tissue Breeding research, and has obtained some gratifying progress.Traditional plant is carried the light source that training adopts and mostly is fluorescent lamp, high-pressure mercury lamp or incandescent lamp, but they are all take human eye as application, visual effect with human eye is up to design principle, rather than be up to design criteria with the physiological effect of plant, thereby biopotency is very low, its radiation energy can't be absorbed by plant efficient, can only be converted into heat energy, and cause environment temperature to raise, and need on the contrary air-conditioning temperature-reducing, cause great energy waste.Plant is considered the energy consumption of air-conditioning heat extraction to their capacity usage ratio less than 0.2% still, and its total energy approach rate is below 0.1%, and light efficiency is low, and caloric value is large, and energy consumption cost accounts for the 40-50% of its operating cost.The abosrption spectrogram of the plant chlorophyll that records according to botanists, chlorophyll mainly concentrate on the purple light of the 610nm of the visible light～ruddiness of 700nm scope, the blue light of 425nm～490nm scope and 390nm～410nm scope to sun Optical Absorption.

Because LED has high-photoelectric transformation efficiency, volume is little, the life-span is long, wavelength is fixing and several the advantages such as low heating, the system of comparing the artificial light sources such as present use fluorescent lamp or high-pressure mercury lamp has light quantity capable of regulating, light quality (ratio of red, indigo plant or purple light) capable of regulating, cooling load is low and the advantage such as permission raising unit are cultivation amount.Some LED plant lamps occurred afterwards, but the aluminium base that they are mostly installed is plane mode, because the led light source light-gathering is stronger, so that the different parts of plant does not receive enough energy; Some plant lamps are with louvre, but its louvre all has been put on the encapsulating shell of light fixture, can not make very fast the shedding from aluminium base ground of heat, so that the LED light decay is serious, cause the LED plant lamp seriously to reduce service life; The most important thing is that they all do not consider plant in the illumination demand different characteristics of different growing stages to red, blue, purple three kinds of light sources, combination of light sources is comparatively single, is unfavorable for that plant better grows.

Summary of the invention

Technical problem to be solved by this invention is, according to plant in different growth periods the different characteristics of illumination demand to red, blue, purple three kinds of light sources, a kind of device of regulating the proportioning of three kinds of light sources is provided, thereby plant is better grown.

The device of adjustable light sources combination of the present invention comprises: the light fixture fixed port; Package is uniform-distribution with a certain size louvre of definite shape on the package; The package the inside is equipped with controller and electric wire access interface; There is bucker the package outside; Hollow cavity aluminium base is uniform-distribution with a plurality of lamp set units on the aluminium base, the cavity top has louvre, and the LED cellular installation is on aluminium base, and the aluminium base outside is equipped with reflection shield; The reflection shield outside is diffuser.

Described aluminium base has certain radian, and the band louvre, very fast the shedding from aluminium base of heat that the LED that makes on the one hand produces, and the light that the LED that makes by the camber design on the other hand launches can satisfy the demand of plant different parts.

Described reflection shield is lucite.

Said apparatus of the present invention utilizes the method for led light source coordinate plant growth, it is characterized in that selecting to utilize the mixed light of different LED light source that plant is shone, with Promoting plant growth, the mixed spectrum combination of the selection of led light source and different LED light source is pressed following method: a. according to the plant chlorophyll absorption spectrum, spectral wavelength that select to determine plant growth is had facilitation is 610nm～700nm, 425nm～490nm, three wave bands of 390nm～410nm, determines to utilize red LED, blue led and purple LED to be radiation source from face; B. according to plant different growing stages chlorophyll to three kinds of Optical Absorption energy ratio, determine that the energy ratio that plant is in three kinds of light of the red royal purple of Seedling Stage is 15:3:3; The energy ratio that plant is in three kinds of light of red royal purple of growth stage is 15:7:3; The energy ratio that plant is in three kinds of light of red royal purple in florescence is 15:5:3; C. determine that according to three kinds of energy ratio of step b) the lamp set unit of LED comprises that red-light LED quantity is that 15, blue-ray LED quantity are seven, purple LED quantity is three, red, blue, purple three kinds of photochromic LED of difference are connected in parallel, identical photochromic being connected in series, and by three kinds of luminous numbers of photochromic LED of contactor control, thereby satisfy the plant different growing stages to the energy requirement of three kinds of light.
