Fig. 2 show PWM according to embodiments of the present invention and exports schematic diagram.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be described.
First embodiment based on invention, a kind of shading process in intelligent illuminating system, comprise the following steps: A, by remote equipment obtain user color of object data, according to the PWM output valve that the output of color of object data is corresponding, wherein color of object data include red colored lamp brightness value R, green light brightness value G, blue lamp brightness value B；B, compare PWM output valve and current PWM output valve to obtain residual quantity, calculate PWM variable according to progressive mode；C, based on PWM variable change lamp brightness with realizes mix colours.
By the equipment such as smart mobile phone or computer, arrange one and take color image, the color that user is liked by click carrys out setpoint color, smart mobile phone accepts the color of object data of client, i.e. after the rgb value of color, first determine whether the color region belonging to this color, because R in the color of 16, G, the region of B is 0 to 255, 65536 kinds of colors are had after combination, the most in these combinations, the combination that color attribute is similar to or human eye is difficult to differentiate is a lot, design the PWM of correspondence and be loaded down with trivial details in order to adapt to these combinations and do not conform to interests, therefore similar color is classified as same class, distinguish tens of kinds of color types, by setting a regional value, the color meeting this region is attributed to a kind of output color (every kind of output color correspondence one PWM output valve).By comparing this PWM output valve and current PWM output valve, the residual quantity of PWM output valve between the two can be obtained, take progressive manner, the most do not use the mode of disposable directly change, but use the mode gradually evolved, the RGB component (44 of the most former PWM output valve, 66, 88), the RGB component (56 of rear PWM output valve, 116, 232), change frequency can be set as 4 times, so asking for as PWM output valve variable quantity each time is R=(56-44)/4, G=(106-66)/4, B=(232-88)/4, i.e. PWM variable, the PWM being applied on light fixture is changed according to this variable, light fixture is made to complete toning；Can also such as set the PWM variable that changes each time for (12,12,12) by setting fixed increment, be varied multiple times to mix colours.
Step A also includes: set up the memory cell being used for storing the information of pre-set color, and pre-set color is the unified embodiment of rgb value color in certain area；Calculate the RGB difference of color of object data and RGB and value, by judging RGB and value, RGB difference, rgb value affiliated area, the PWM value of the pre-set color of output correspondence.
By setting in advance, the combination of whole colors is divided into tens of kinds of combinations, and using these combinations as pre-set color, judge RGB and value, RGB difference, the rgb value affiliated area of color of object data, then using pre-set color the most corresponding for the representative color in this region as the color exported, then export correspondence PWM value, wherein RGB and value for R, G, B and value, i.e. R+B+G；RGB difference is the difference two-by-two between each colour；Rgb value is the combined value of R, G, B, such as RGB=(1,2,3)=(R, G, B).
According to embodiments of the invention, PWM as shown in Figure 2 exports schematic diagram, rgb value R, G, B of the color data that remote equipment obtains is added, obtains sum, as they and value.The biggest, explanation color is the most bright-coloured to a certain extent, also illustrates that the brightness of color of object is the biggest.For the color of 16, when with the numerical value bigger more than or equal to certain, as 648 time (16 0 ~ 255, group and maximum number be 256 × 3=768), illustrate that the color on each road is the brightest, also illustrate that they mutual gaps are the most little, then this situation is carried out white light judgement, namely final actual output is set to white light, mark white light brightness value is W, and RGB tri-street lamp pearl represents colour lamplight, going out so be disposed as lamp herein, white lamps is then the brightest.The PWM output valve on final each road is (0,0,0,255) (brightness value of R, G, B, W)；When R, G, B value sum of color of object is less than certain smaller value, during such as 43, illustrating that the value of RGB is the least, level off to black, indication lamp goes out, and the PWM output valve on each road all takes a little value, if PWM output valve is (0,0,0,0).
When R, G, B value of color of object differs the least, and e.g., less than 15(can judge by the method mutually seeking difference), illustrate that this color is for white, grey or black.Now can use the mean value PWM output valve as white lamp bead of R, G, B, and due to color of object achromaticity, so the PWM waveform of R, G, B lamp bead is less, then output valve is (0,0,0, (R+G+B)/3).
First carry out the checking of black, white, grey special area, determine the step (i.e. carrying out region judgement according to the RGB in the color of object data of the former input of user) extracting pre-set color after being not belonging to these several situations the most normally, because under these special areas, need not the light fixture to red, green, blue and carry out energy supply, as conservation measures, it should preferentially carry out the process of special area.
One can be classified as about the scope in region, the such as color of (0,64,64) and (32,64,64), so take the PWM output valve that (16,64,64,0) are this kind of color, all (0 ~ 32,64,64) the corresponding PWM output valve of the color combination of scope is (16,64,64,0).
Step B also includes defining progressive variable, obtains PWM variable by Step wise approximation value.
Progressive variable is defined when realizing progressive, as by number of times or by fixed value progressive, or utilize approximation theory, the i.e. function of definition one approximation replaces complicated conversion curve, function beginning and end corresponding current PWM output valve, target PWM output valve, progressively extract the value on this function as output valve (because lamp brightness is non-linear with energy supply relation, need a suitable function to state transformation relation, a suitable function can be obtained after multiple authentication).Operation step number when the PWM output valve corresponding according to current lamp bead and the difference (positive and negative) of target PWM output valve determine progressive and mode of operation (progressive number of times, number of times is the biggest, is taken time the most, and progressive effect is the best, but time delay increases, need to determine according to the needs of illuminator).
Step C also includes the PWM output valve after having recorded toning, marks it for current PWM output valve.
Record the PWM output valve after toning, using the basis as variable color next time, i.e. current PWM output valve.
The second embodiment based on invention, a kind of tinting system in intelligent illuminating system, including with lower module: far module, for being obtained the color of object data of user by remote equipment, according to the PWM output valve that the output of color of object data is corresponding, wherein color of object data include red colored lamp brightness value R, green light brightness value G, blue lamp brightness value B；Control module, is used for comparing PWM output valve and current PWM output valve to obtain residual quantity, calculates PWM variable according to progressive mode；Light emitting module, for changing lamp brightness to realize toning based on PWM variable.
The above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as it reaches the technique effect of the present invention with identical means, all should belong to the protection zone of the present invention.In the protection zone of the present invention, its technical scheme and/or embodiment can have various different modifications and variations.
