The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model embodiment is according to the rgb color space principle, employing RGB sensor is gathered the three kinds of change in color of R, G, B in the outdoor sunlight, drive the driving intensity of chip by controller control, the adjustment that drives chip causes the luminosity of the LED lamp that drives can simulate brightness and colourity through the sunshine of window.
The structural principle based on the simulation window of RGB three-color LED light that Fig. 1 shows that the utility model embodiment provides for convenience of explanation, only shows the part relevant with the utility model embodiment.
The controller 2 that is connected with RGB sensor 1, the chromatic value that controller 2 is gathered according to RGB sensor 1 sends control instruction control and drives chip 4.
At least one that is connected with controller 2 drives chip 4, drive the control instruction that chip 4 receives controller 2, send and drive the signal controlling current's intensity, electric current by control LED lamp 5, thereby the luminous intensity of control LED lamp 5, the luminous intensity of LED lamp 5 changes according to the variation of the intensity of the light that sees through window.In the utility model embodiment, drive chip at least one, when LED lamp 5 more for a long time, can dispose a plurality of driving chips.
Disperse the transmission medium of the light that glass 6 sends as LDE lamp 5, light that LDE lamp 5 sends is through dispersing the more approaching light that sees through in the window inlet chamber behind the glass 6, through dispersing after the glass 6, can guarantee that indoor light is softer, and similar to the luminous intensity of real window with colourity, reach the effect of the daylight of the true window transmission of emulation.
The control signal of controller 2 outputs is input to and drives in the chip 4, drives chip 4 according to different input signals, and the driving of varying strength is provided for LED lamp 5.The effect of LED lamp 5 daylight of the true window transmission of emulation under the drive condition of varying strength.The variation of the LED lamp 5 by R, G, three kinds of colors of B, make light that LDE lamp 5 sends through dispersing the more approaching light that sees through in the window inlet chamber behind the glass 6, through dispersing after the glass 6, can guarantee that indoor light is softer, and similar to the luminous intensity of real window with colourity, reach the effect of the daylight of the true window transmission of emulation.
As an embodiment of the present utility model, keyboard 3 is input to controller 2 with user's customized demand signal, and the brightness of controller 2 control LED modules with different colors lamps 5 arrives user's setting requirement.
The structure based on the simulation window of RGB three-color LED light that Fig. 2 shows that the utility model embodiment provides for convenience of explanation, only shows the part relevant with the utility model embodiment.
All comprised R, G, B three looks in each LED lamp, the light that all LED lamps send sees through to be dispersed glass 6 and shines indoorly, reaches the effect of the daylight of the true window transmission of emulation.The quantity of LED lamp 5 can change according to simulating varying in size of window.
A preferred embodiment as the utility model embodiment, the chromatic value of the R chromaticity transducer collection in the RGB sensor 1 only can change the electric current on the LED lamp 5 that is carried in the R look, the chromatic value of G chromaticity transducer collection only can change the electric current on the LED lamp 5 that is loaded into the G look, and the chromatic value that the B chromaticity transducer collects only can change the electric current on the LED lamp 5 of B look.
As the preferred embodiment of the utility model embodiment, controller 2 adopts the electric current of the method control LED lamp 5 of pulsewidth modulation (PWM).
Can calculate the dutycycle of controlling the pwm signal that drives chip 4 according to certain algorithm after the data of three chromaticity transducers of controller 2 receptions and (be loaded into R, G, the dutycycle of the pwm signal on three kinds of LED modules with different colors lamps 5 of B is subjected to the control of R chromaticity transducer, G chromaticity transducer, B chromaticity transducer respectively).
In the controller 2 chromatic value that collects is divided into several grades, the situation of the many more adaptations of grade is just many more, can divide chrominance levels (because R as the case may be, G, so B three looks ratio difference in sunshine is R, G, the divided rank of three kinds of colourities of B is generally different).
With the example that is divided into of R chromatic value, generally this chrominance levels can be divided into 3 grades, greater than x1, smaller or equal to x1 greater than x2, smaller or equal to x2.The brightness of gathering when chromaticity transducer is during greater than x1, and the dutycycle that controller 2 will be loaded into the PWM on the R colored lights is set in a fixed value, and the brightness of R look LED lamp is not changed with the change of extraneous light.When the brightness of gathering smaller or equal to x1 during greater than x2, controller 2 is loaded into the dutycycle of the pwm signal on the R colored lights according to this chromatic value control of gathering, make the brightness of R look LED lamp follow the variation of outside brightness and change, promptly imitate the brightness of R look in the outside sunshine.When brightness during smaller or equal to x2, the dutycycle that controller 2 will be loaded into the PWM on the R colored lights is set in a fixed value, and the brightness of R look LED lamp 5 is not changed with R chromaticity transducer value.In like manner, with the G chromaticity transducer, the some grades of division of B chromaticity transducer value are controlled the dutycycle that is carried in the pwm signal on G look LED lamp and the B look LED lamp respectively according to the requirement of different brackets.The value that corresponding chromaticity transducer is all being followed in the brightness of the LED lamp of such three kinds of colors changes, and the colourity that can make lamp is more near sunshine.
An embodiment as the utility model embodiment, the adjusting of brightness value can also be undertaken by keyboard 3, make brightness reach the highest or reach certain brightness value, to satisfy various different requirements, keyboard 3 is input to controller 2 with user's customized demand signal, and the brightness of controller 2 control LED modules with different colors lamps 5 arrives user's setting requirement.
