Embodiment
Below by drawings and examples, technical scheme is described in further detail.
The invention provides a kind of dynamic lighting method of variable color temperature, in dynamic lighting device, being shone by dynamic
Bright device provides the illumination light of colour temperature dynamic change to user in normal lighting.
In order to be better understood from dynamic lighting method proposed by the invention, the original changed first to human eyes structure with light
Reason illustrates：
When the parameters such as the illumination of injection human eye light, colour temperature, luminous intensity, luminous flux, angle change, the rainbow of human eye
Film will change the size of active accommodation pupil with light, so as to control luminous flux.The athletic meeting of iris drives ciliary muscle movement, eyelash
The motion of shape flesh will also drive lenticular motion, so-called " eyes link depending on photosystem three " in visual field so as to produce.
Above-mentioned iris, ciliary muscle and lenticular ganged movement change the physiological structure for making eyes, i.e., iris, ciliary muscle and
Changed in lenticular shape and/or size.
The dynamic lighting method of the present invention is to be proposed based on above-mentioned principle.
Fig. 1 is the flow chart for the dynamic lighting method that the present embodiment provides, as shown in figure 1, dynamic lighting method is included such as
Lower step：
Step 10, the power supply output module of dynamic lighting device exports the first power supply signal according to illumination control signal；
Specifically, the power supply output module of dynamic lighting device is the mould for providing driving power signal to Lighting Division
Block.Regulation driving power signal is the first power supply signal, and the electrical parameter of the first power supply signal changes including one or more groups of dynamics
Electric parameter.In the case of for multigroup electric parameter, multigroup electric parameter is divided into multiple-channel output.
Electric parameter can specifically refer to electric current and voltage, including the electric current of the magnitude of voltage of voltage, rate of change, electric current is big
Small, rate of change etc.；Or can also be both voltage and currents it is therein any one；It can also refer to output module output of powering
Switching state.
Output module of powering exports the first power supply signal, can be exported according to the input instruction of user, can also
It is to be exported according to presetting.
In the first scheme, power supply output module can receive the Lighting control instruction of user's input, generation illumination control
Signal processed, and the first power supply signal is exported according to illumination control signal.
Receiving user's input Lighting control instruction can realize especially by wired or wireless way.
Such as the light illumination mode selection key by being set in sensing user touch dynamic lighting equipment, or pass through nothing
Line transmission receives the remote input that user operates the Lighting control instruction that remote control equipment is carried out.
In scheme in second, the power supply output module of dynamic lighting device is according to default illumination control signal output the
One power supply signal.
Default illumination control signal can be stored in the memory of dynamic lighting device, by power supply output module to depositing
Reservoir is read out acquisition.Memory can be rom chip or the solid state non-volatile semiconductor memory of any other type.
The mode that default illumination control signal is write in memory can be realized by wired input mode, can also be passed through
The interface of memory, such as infrared interface, blue tooth interface, USB interface etc. are connected to realize.
Step 20, one or more Lighting Divisions of dynamic lighting device produce colour temperature under first power supply signal driving
The optical signal that dynamic changes, so as to the illumination light of dynamic lighting device output colour temperature dynamic change；
Specifically, it can also be multiple that Lighting Division, which can be one, in dynamic lighting device, it is connected with power supply output module
Connect.When for it is multiple when, can be multiple Lighting Divisions according to same group of electric parameter control driving or multiple lighting part
Driving is not controlled by multigroup electric parameter of multiple-channel output.Therefore, multiple Lighting Divisions can be same under the driving of the first power supply signal
When produce colour temperature dynamic change optical signal, can also timesharing produce colour temperature dynamic change optical signal.
Further, illuminator included in Lighting Division, can be same or not of the same race, each illumination
The illuminator that portion includes is one or more, and these illuminators are lighted or closed or change under the driving of the first power supply signal
Become its light emission color temperature, so as to which the change that the overall optical signal to each Lighting Division exports acts.
The power supply signal to each Lighting Division in multiple Lighting Divisions is exported, can be to all being lighted in the Lighting Division
Body exports same group of electric parameter or exports one group of electric parameter to a part of illuminator, to another part illuminator
Export another group of electric parameter, that is to say, that, can be only for Lighting Division, illuminator in the method that the present embodiment provides
Vertical control.
In a specific example, output can be changed by dynamic and be sent out to all illuminators in Lighting Division or part
The electric current and voltage of body of light, or the two it is therein any one, to change the light emission color temperature of these illuminators, so as to realize illumination
Portion exports the colour temperature dynamic change of optical signal.
So that illuminator is power type white light LED as an example, colour temperature can be changed by changing electric current.
With the driving current increase of device, the colour temperature of power type white light LED can gradually increase.Because electric current adds
After big, the blue light that chip is sent increases, and the thickness of phosphor powder layer is certain, then blue light composition increase in the white light of outgoing,
So that the colour temperature increase of device.
In another specific example, can by dynamic-on or disconnect electricity output module into Lighting Division it is not of the same race
The power supply of illuminator is exported to realize.In a preferred embodiment, there are 100 individual luminaires, specifically in Lighting Division
Some yellow light LED and some white light LED can be included, the power input of each illuminator is that independent control turns on and off
's.Which part is first turned on by power supply signal control, for example whole yellow light LEDs is opened in control first, then every 0.1 second
A White LED is opened in increase, and until whole illuminators are all lighted, a White LED is closed in control in every 0.1 second afterwards, until
Whole White LEDs are all closed, and repeat the process that White LED opens and closes one by one, while yellow led is persistently remain on,
It is possible thereby to realize the colour temperature dynamic change of Lighting Division output optical signal.
No matter use and independence carried out to Lighting Division or is uniformly controlled, or illuminator using independence or is uniformly controlled,
In order to not influence normal use demand of the user for lighting device, the first power supply signal driving Lighting Division produces dynamic and changed
Optical signal, caused by its entirety dynamic lighting device output illumination light colour temperature within any one 0.1 second period change

The sensation of this light elephant maintains a limited time, and this physiological phenomenon is called the persistence of vision.It is bright for varying environment difference
Degree, the length of retentivity time of eye difference, brightness is stronger, and the retentivity time of eye is shorter.And for making for lighting device
With environment, in the environment of intermediate light, the retentivity time of eye is about 0.1 to 0.4 second.Thus in 0.1 second time range, lead to
The change for crossing setting colour temperature is not more than 10K, to ensure that change of the light within each retentivity time of eye is small, makes
The user of lighting device can not perceive the colour temperature of illuminating ray and change, so as to which the normal use to user will not
Produce any influence.
The change of colour temperature is needed within the specific limits, to meet the needs of being illuminated.The change model of colour temperature in this example
2500K is trapped among between 6500K, to meet the lighting demand under indoor environment.
