Embodiment
The embodiment of the present invention provides a kind of lighting device and control method thereof and control system.
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
The difference obtaining the color of irradiated object by projection detected light in prior art adjust lighting device issue permit and penetrate in the process of light, the reverberation that may exist due to other objects makes object color identification deviation large, and then causes the problem being difficult to select the irradiation light coordinated with irradiated object true colors.The embodiment of the present invention provides a kind of control method solving the lighting device of foregoing problems, describes this method in detail below in conjunction with accompanying drawing.
Fig. 1 is the flow chart of the control method of lighting device in the embodiment of the present invention, the executive agent of this control method can be mounted in the control circuit board in lighting device, comprise Micro-processor MCV, sensor Various Components in this control circuit board, in these elements and lighting device, multiple element such as such as light emitting source, power source drive unit and the power supply that may exist realizes being electrically connected by wired or wireless mode.
Wherein, in the process that the light emitting source of lighting device illuminates routinely to irradiated object, this control circuit board periodically starts aforementioned control method, during to guarantee that irradiated object occurs to change, and can the irradiation light that sends of the light emitting source of rapid adjustment lighting device.
Aforementioned control method comprises the steps.
S10, startup lighting device are to irradiated object projection initial scout light.
In the embodiment of the present invention, initial scout light can be projected by the light emitting source of lighting device.When starting this control method, in advance original for the light emitting source of lighting device sent out irradiation light is closed down, then open projection detected light.
Certainly, can also in lighting device another independently auxiliary light emission source built-in, after original for the light emitting source of lighting device sent out irradiation light is closed down, detected light is projected by this auxiliary light emission source, only need the driver element of this auxiliary light emission source and lighting device and power supply to be electrically connected, do not repeat at this.
In the embodiment of the present invention, initial scout light is chosen as white light, and the colour temperature of white light can be selected among 2000K to 30000K scope, also can be selected among less 2500 to 25000K scope.Optical width due to white light is wider and currently disturb without other color of light, can obtain the reverberation of irradiated object more accurately.
Certainly, initial scout light also can adopt other color of light except white light, does not repeat at this.
No matter by the light emitting source of lighting device or another independently auxiliary light emission source, LED all can be adopted as light source, and utilize RGB, RGBW light mixing way, make the light source passage that shades of colour LED light source forms, to form mixed light permutation, and carry out build-up of luminance and brilliance control by the light source passage of driver element to each color, realize light modulation toning function.
The light emitting source of certain lighting device or another independently also can adopt the other types such as TL lamp, Halogen lamp LED in auxiliary light emission source, does not repeat at this.
The initial reflection light of S20, acquisition irradiated object.
In the embodiment of the present invention, can by arranging towards the transducer of irradiated object on lighting device, the initial reflection light based on initial scout light is obtained by this transducer, and the RGB signal of telecommunication be converted into for embodying color, this is technology well known to those of ordinary skill in the art, does not repeat at this
S30, obtain the priming color of irradiated object according to initial reflection light.

S40, close down lighting device to irradiated object projection initial scout light.
In the embodiment of the present invention, when performing this control method, started by the pulse width modulation (PWM) signal preset and closed down light emitting source in lighting device and project detected light to irradiated object, lighting device is opened and closed down to property performance period to irradiated object projection initial scout light.Be convenient to the later stage when gathering the environmental colors at lighting device place, can not be subject to can not issuing permit and penetrate light and affected by illuminated device.
By heightening the frequency of pwm signal, observer is difficult to discover the opening and closing of light emitting source in lighting device, thus ensures Consumer's Experience.
The environmental colors of S50, acquisition lighting device place environment.
In the embodiment of the present invention, the environmental colors of lighting device place environment can be gathered by the transducer for gathering reverberation, this environmental colors embodies the color impurities among except many reverberation that can be entrained in irradiated object such as the reverberation of other external objects of shone thing or the utilizing emitted lights of other lighting devices, because lighting device is closed down to irradiated object projection initial scout light, collected environmental colors then can be made can not to issue permit and penetrate light and affected by illuminated device, ensure its accuracy.
S60, environmentally color revise priming color, obtain revising rear color.
In the embodiment of the present invention, the initial reflection light being revised irradiated object by environmental colors is adjusted back reflection light, and then obtain revising rear color according to the reverberation after adjustment, reduce surround lighting for the interference of irradiated object reverberation, with obtain more accurate, with irradiated object true colors closer to correction after color.
Shown in composition graphs 2, in the embodiment of the present invention, step S60 specifically comprises the steps:
S61, judge whether environmental colors meets default environmental colors condition, if so, perform step S62, if not, perform step S63.
Wherein preset environmental colors condition specifically to comprise: environmental colors is lower than default environmental colors value.Default light value can be preset according to lighting device place environment, and such as, among the market that environment light is more, adaptability improves presets environmental colors value, reduces the interference of surround lighting for irradiated object reverberation.
S62, obtain color after the correction identical with priming color.
When environmental colors is positioned at acceptable scope, can be considered that surround lighting can be ignored for the interference of the reverberation of irradiated object, now directly select color after the correction identical with priming color, color and its true colors of the irradiated object of acquisition are basically identical.
The color of S63, adjustment initial scout light, obtains the rear detected light of at least one adjustment.
When environmental colors exceeds acceptable scope, surround lighting is comparatively large for the interference of the reverberation of irradiated object, then need to reduce the interference of surround lighting for irradiated object reverberation.
