Embodiment
Elaborate below in conjunction with the embodiment of Figure of description to the embodiment of the present invention.
MultiLED(MultiColorLED is selected in the present embodiment) as polychromatic light, software control can be coordinated to send the button light of multiple different colours, by R(Red according to the hobby of user), G(Green), the MultiLED of B (Blue) three kinds of monochromatic LED chips encapsulation combination.Fig. 1 is the cut-away view of three-color LED, wherein A1, A2, and A3 is independently controlled by three I/O ports of MCU, and C1, C2 and C3 can be connected altogether.The annexation of three-color LED light and MCU and surrounding module thereof is shown in Fig. 2, when three I/O ports of MCU export different pulse width signal (PWM), can the luminosity of control RGB tri-monochromatic LED chips, thus be mixed into different colors.The principle of luminosity of foundation optics and LED, follow following rule when RGB tri-look mixes:
Wherein:
Coordinate and the brightness symbol of RGB tri-kinds of monochromes and secondary colour can see table 1 and tables 2
Table 1
Table 2
Table 3
From the characteristic of LED, PWM effective value ratio or analog current size have direct impact to its brightness, obtain the chromaticity coordinate value of color of object with RGB, only need change the brightness of RGBLED
y 1/
y 2/
y 3, prerequisite must ensure that LED is in the current margin allowed.
Ownership goal color is provided with two kinds of different approaches: selecting type and self-defined formula, the corresponding RGB brightness value of different set-up modes
y 1/
y 2/
y 3computational process, pwm signal parameter storage mode are also had any different.
First kind of way: selecting type
In vehicle entertainment system is arranged, add color selecting arrange, and the coordinate figure of these colors input MCU is calculated corresponding RGB brightness value
y 1/
y 2/
y 3(passing through formulae discovery), then obtains corresponding pwm signal parameter by the method for debugging, and by the mapping relations between often kind of color and RGB brightness value and the mapping relations between RGB brightness value and pwm signal parameter stored in E
2in PROM.User only needs to select any one color of object in lists, and MCU can read corresponding pwm signal parameter information, then exports corresponding pwm signal in MultiLED by IO port.Adopt in this way, user can indiscriminately ad. as one wishes change the color arranged in list.
The second way: self-defined formula
If user is arranging in list the color of object that can not find and oneself like, can also obtained by self-defining mode.First the brightness of RGB
y 1/
y 2/
y 3scope carries out quantizing and is evenly distributed in arranging in the litter on hurdle, and see Fig. 4, user only needs manual adjustments to obtain the parameter of needs
y 1/
y 2/
y 3.Then input the coordinate figure that MCU calculates color of object, finally change into pwm signal and output in MultiLED.Log off setting after user sets color, and MCU is the PWM parameter read-in E mixed up
2pROM, directly to call next time.
More than describe and can find out, the mixing of light color mainly relies on change RGB luminosity to obtain.And the brightness of LED equals RGB brightness sum after mixing, namely
y 1+
y 2+
y 3.So also need the brightness value again adjusting the rear LED of mixing after user obtains the color of needs, as shown in Figure 5, otherwise the inharmonious of automotive trim lighting effects can be caused.As can be seen from the formula of chromaticity coordinate, when
y 1/
y 2/
y 3when proportional increase or minimizing, after mixing, LED also can increase pro rata or reduce brightness, and can not affect target color coordinate value.
User carries out the flow chart of press key lamp light color setting as shown in Figure 6, and the existing software-controlled manner to the change of button light LED color is described.Whole process comprise user arrange,
y 1/
y 2/
y 3calculate and the storage of pwm signal parameter.
After MultiLED powers on, the pulse width signal parameter of last memory location in system automatic acquisition memory, export corresponding pulse width signal sends certain color light with control MultiLED, if user is unsatisfied with current light color, then arrange selecting type or self-defined formula pattern by Users panel to carry out light color and choose, if arrange selecting type pattern to choose light, system ejects color selecting list and selects for user, as shown in Figure 3, when after selected a certain color of object wherein, system according to the coordinate figure consults memory of color of object to obtain the input pulse width signal parameter of each monochromatic LED chip, the coordinate figure of color of object is previously stored with in described memory, relation mapping table between the light emission luminance value of each monochromatic LED chip and the input pulse width signal parameter of each monochromatic LED chip, according to corresponding pulse width signal parameter output pulse width signal to the input control end of each monochromatic LED chip, each monochromatic LED chip sends the light of corresponding bright under the control of pulse width signal, the color of object light that whole MultiLED will send can be obtained after the RGB light mixing of each brightness, if user chooses light color of object by self-defined formula pattern, then system ejects and arranges hurdle with each monochromatic LED chip brightness regulation litter, as shown in Figure 4, user regulates the brightness of each single colored chip to obtain required color of object by litter, simultaneous memory preserves the mapping relations between this self-defining color of object and the brightness of RGB single colored chip and the mapping relations between the brightness of RGB single colored chip and rgb signal parameter automatically, directly to call next time.
Polychromatic light light control method provided by the invention both can meet user to light color diversified demand, can reduce again the design cost of producer and the complexity of project management, have good market prospects.
The above embodiment only have expressed preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
