Embodiment 2
Present embodiment relates to field, garden is divided into several regions and carries out the cultivation method of night illumination and the lighting device for this under by the different illuminate condition in each region.Chrysanthemum is short-day plant, just not blooms if the duration of day does not shorten.Utilize this character to carry out according to the electron irradiation cultivation of controlling the date of blooming the listing date of chrysanthemum.In present embodiment, the night illumination of this electron irradiation cultivation is undertaken by yellow led and the illumination of controlling and these two kinds of effects of the vermins-proof effect of moth are had both of blooming is provided, and is conceived to the LED control of easily glimmering.
Below, the example of electron irradiation cultivation is described.After chrysanthemum field planting, during regulation, carry out night illumination, highly grow to 50～60cm and Si Bule chrysanthemum (spraymum) lighting-off while highly growing to 20～25cm Wheels chrysanthemum.In addition, about 50 days, the condition (short-day condition) of non-processor is lower continues cultivation, when it highly grows to 90cm left and right, bloom, gather in the crops.Therefore, in actual cultivation, first determine and bloom day, carry out inverse operation with this and determine field planting day.
Figure 10 is the figure that represents the cultivation method of the chrysanthemum of present embodiment.In 3 row fields of field, garden 70, field planting has chrysanthemum, by each field called after region A, B, C respectively.In mode of from top irradiating chrysanthemum corresponding to each region, illuminating part 210A, 210B, the 210C of lighting device 200A, 200B, 200C is set.Because the directive property of the ejaculation light of LED is stronger than fluorescent lamp, thereby can make each lighting device 200A, 200B, 200C irradiate separately respectively each region A, B, C.
Figure 11 is the figure that represents the cultivation step of chrysanthemum.Conventionally, after field planting, implement night illumination, before approximately 50 days of the pre-settled date of blooming, be made as non-processor.Suppress to be not applied to owing to blooming the non-processor in the situation that, thereby after 50 days, bloom greatly.
In the present embodiment, after field planting, after the illumination cultivation carrying out the control model of blooming described later during the first illumination cultivation, during the second illumination cultivation, switch to the non-suppression mode (aftermentioned) of the blooming results of blooming thus.Now, make respectively the degree suppressing of blooming during the first illumination cultivation be changed by the change of duty factor for region A, B, C, the results that can make to bloom stagger period.
At this, to blooming, control model and the non-suppression mode of blooming are illustrated (control model of blooming of broad sense also comprises the non-suppression mode of blooming).As shown in Figure 9, chrysanthemum reach florescence number of days because duty factor is different, there is the duty factor higher trend of inhibition of blooming more greatly.Be conceived to this characteristic, set different duty factors by each region, a day dispersion thus can make to bloom.
In the lighting device 200 of Figure 10, the formation that employing can make the duty factor of night illumination switch.For example, the illumination of each lighting device 200 is made as to 10 luxs, the dark phase width of the control model of blooming during the first illumination cultivation is set as respectively: lighting device 200A is that 0 (bright light continuously), lighting device 200B are that 20ms (duty factor 50%), lighting device 200C are 100ms (duty factor 17%).In addition, the bright phase width of all lighting devices is all made as to 20ms.Like this, as shown in Figure 9, due to the dark short side of phase width, to be that a side that duty factor is large reaches florescence number of days elongated, thereby can bloom day to each area change.
In addition, day postpone by make period that night illumination pattern is switched postpone successively also can make to bloom in each region.As shown in Figure 12 (a), implement night illumination by lighting device 400 described later, before approximately 50 days of the pre-settled date of blooming, be switched to the non-suppression mode of blooming (dark phase width 200ms (duty factor 9%)) from the control model of blooming (bright light continuously).Now, stagger in turn period by region A, B, C the period of switching by pattern and carry out, can make the day of blooming in each region postpone.
In addition, by making simply field planting day postpone and also can make to bloom a day dispersion by each region.As shown in Figure 12 (b), by the condition of bloom control model and the non-suppression mode of blooming in each region (during bright phase width, dark phase width, illumination) is made as identical and field planting day is postponed respectively to a few days, the day that can make to bloom postpones respectively a few days.
Day can control by each region if bloom, day disperse owing to blooming, thereby convenience when results is high.Having solved blooms as now concentrates problem very busy while results day.
In addition, now in technology, owing to being non-processor thereby can not avoiding the sudden of nocturnal moth class adult to duration of flowering from finishing during night illumination, but, according to this present embodiment, even during this period, also can obtain anti-moth effect by the illumination of the non-suppression mode of blooming.In addition, in prior art, for the control of blooming, be attended by each interregionally by loaded down with trivial details operations such as window-blind separate, still, according to present embodiment, the setting by lighting device is switched and is just completed, thereby convenience is high.
Figure 13 is the circuit structure diagram of lighting device 400.Lighting device 400 possesses illuminating part 410A, 410B, 410C, and it is connected with drive division 120 via switch 401A, 401B, 401C respectively.Drive division 120 possesses the drive division 120B that the control model of blooming the drive division 120A using and the non-suppression mode of blooming are used, drive division 120A is that continuous bright light drives, and the bright phase width of drive division 120B is that 20ms and dark phase width are 200ms (duty factor 9%).According to this formation, can carry out the switching of pattern by the switching of switch.In addition, even drive division also just completes by two in the situation that setting up illuminating part, it is favourable that the manufacturing cost of illumination apparatus reduces.
In addition, although the control model of blooming is made as continuous bright light,, in order to regulate its illumination, also can be as described in embodiment 3, also make the worm of insect protected object in carrying out during continuous bright light and pulse width modulation that the plant cultivated can be felt continuous bright light.
Embodiment 3
In present embodiment, the waveform of LED pulse is further carried out in bright phase width to pulse width modulation.
With regard to the waveform of the LED pulse of present embodiment, as shown in figure 14, bright phase width in a light and shade cycle is 20ms, during turning off the light during bright light and in the bright phase width of 1ms in the bright phase width of for example 1ms of its chien shih, alternately repeat 10 times and form, in width of bright phase, duty factor is made as 50%.In addition, duty factor is to indicate in phase width during bright light/(in bright phase width during bright light+during turning off the light in bright phase width) in so-called bright phase width.
Accordingly, nocturnal moth class adult is difficult to identify as flicker during bright phase width is turned off the light during bright light and in bright phase width in bright phase width, can be estimated as being considered as continuous light.
According to present embodiment, effective bright phase width on continuing for a long time at the light adaptation state that makes nocturnal moth class adult can be kept with its lower limit 20ms, reduce the lighting time amounting to.Therefore, anti-moth effect is not greater loss, can realize the minimizing of power consumption, and the inhibition of blooming of chrysanthemum is reduced.
Embodiment 4
Present embodiment possesses the formation that illumination intensity is changed according to the height of chrysanthemum.

Table 3 represents that the A1GaInP that yellow fluorescence LED and embodiment 1 use is the characteristic comparison of yellow led.
Table 3
In addition, relatively the A1GaInP of use is that yellow led is the device that does not contain fluorophor and chip self ejaculation sodium yellow.The luminous efficiency of comparison sheet 3 learns, the luminous efficiency of yellow fluorescence LED is yellow led excellence than A1GaInP.
Figure 19 be the yellow fluorescence LED of present embodiment and relatively the A1GaInP of use be the spectral distribution graph of yellow led.In addition, yellow fluorescence LED and relatively the yellow led of use drive by same current value.
In Figure 19, if the discernible wavelength of nocturnal moth class 450～600nm region to yellow fluorescence LED115 and relatively the A1GaInP of use be that the luminous efficiency of yellow led compares, the luminous efficiency of yellow fluorescence LED115 is high.Therefore,, by making lighting device 100 possess yellow fluorescence LED115, can further improve energy-saving effect.
In addition, the approximately blue light composition below 500nm in the spatial distribution of Figure 19 is sometimes along with the kind of nocturnal moth class produces attractant effect.For eliminating this impact, preferably for example make the colour filter of the following cut-off of 500nm be arranged between lighting device 100 and autumn chrysanthemum 60 filter of the transmission that suppresses this blue light composition.
In addition, as fluorophor 118, except BOSE, can also be applicable to using SOSE (Sr, Ba, Si, O, Eu), YAG (Ce activates yttrium-aluminium-garnet), α Sialon ((Ca), Si, Al, O, N, Eu) etc.In addition, also can, by LED chip 116 is adopted to ultraviolet (near ultraviolet) LED that for example peak luminous wavelength is 390nm～420nm from the device of blue-light-emitting, realize the further raising of luminous efficiency.
Figure 20 (a) is the figure that represents the response characteristic of the ejaculation light of yellow fluorescence LED, and transverse axis is time (1ms/div), and the longitudinal axis is luminous intensity.As shown in Figure 20 (a), bright phase width 20ms, dark phase width 20ms (duty factor 50%) much less situation, be exactly the situation of bright phase width 1ms, dark phase width 1ms, penetrate light and also follow pulsed drive current and occur.Fluorophor possesses and sends twilight sunset during of short duration after exciting light extinguishes and the character of decay gradually along with the elapsed time, but, if dark phase width is longer than 1ms, with respect to the waveform of driving pulse electric current and the persistence of fluorophor extremely short, thereby can think that penetrating light can follow driving pulse electric current and occur.
Like this, use yellow fluorescence LED, can accurately obtain the flicker of regulation with the flicker cycle shown in embodiment 1 (bright phase width 20ms, more than dark phase width 20ms (duty factor 50%)).
Figure 20 (b) represents that relatively the A1GaInP of use is the figure of the response characteristic of the ejaculation light of yellow led.Be that yellow led also can obtain the response wave shape of equal (in theory higher than this high-speed response) with yellow fluorescence LED for A1GaInP, certainly also can accurately obtain the flicker of regulation.
