Description
Technical field
The present invention relates to a kind of mobile unit, especially a kind of mobile unit that front-panel led lamp color can be set by the user.
Background technology
Along with mobile unit being widely used of automotive field, people are more and more stronger to personalization, the foolization demand of mobile unit.As everyone knows; The front-panel led lamp color of tradition mobile unit shows dull; Can not satisfy the collocation demand of different automobile types, same vehicle different colours; Because of light need a kind of easy to operate and can according to the hobby of individuality the mobile unit of front-panel led lamp color be set by the user, to satisfy the aesthetic requirement of different user.
The LED light fixture has advantages such as brightness is high, the life-span is long, is the first-selection of mobile unit backlight.But general LED lamp all is to form with the electroluminescent lamp of solid color; The color of the light that it sends is constant forever; And the color of shell of the automobile of use mobile unit is rich and varied, receives the restriction of mobile unit panel backlight, the inharmonic problem of colour match with automobile appearance can occur; Perhaps can only select several kinds of colors, be difficult to satisfy the demand of dissimilar consumers personalized color.
Summary of the invention
The technical problem that the present invention will solve is to overcome the deficiency of prior art; A kind of mobile unit that front-panel led lamp color can be set by the user is provided; The user can be according to the appearance color of own automobile; The front-panel led lamp color of arranging in pairs or groups different also can arbitrarily be provided with the color of oneself wanting according to hobby or the mood of oneself simultaneously.
For solving the problems of the technologies described above; The basic design of the technical scheme that the present invention adopts is: a kind of mobile unit that front-panel led lamp color can be set by the user; Comprise: color touch-control interface, color control module, LED driver module and front-panel led lamp; Said color touch-control interface: be provided with color commonly used and/or red-green-blue color configuration bar more than three kinds, be used for color settings; Said color control module: be used for regulating respectively the duty ratio and the preservation of the pwm signal of red-green-blue, give the LED driver module with the pwm signal duty cycle transmissions of these three kinds of colors respectively simultaneously according to the color of color touch-control layout setting; LED driver module: be used for duty ratio, drive three-color LED light to obtain the color of color touch-control layout setting according to the pwm signal of red-green-blue; Said front-panel led is the three-color LED light that includes red-green-blue, is used for the color of Show Color touch-control layout setting.
Further; The described mobile unit that front-panel led lamp color can be set by the user; It is characterized in that: the layout setting of described color touch-control has red-green-blue color configuration bar; Wherein red configuration bar comprises 256 kinds of optional settings of subjective brightness, and blue configuration bar comprises 256 kinds of optional settings of brightness, and green configuration bar comprises 256 kinds of optional settings of brightness.
Further; Described color touch-control interface is characterized in that: said more than three kinds color commonly used from arbitrary color of red-green-blue or appoint second colors to make up resulting color or three kinds of colors of RGB and make up the resulting color in any brightness ratio and select in any brightness ratio.
As user during from the color of selecting the color commonly used more than three kinds to like of color touch-control interface display; Choose color through the color touch; The color control module is regulated the duty ratio and the preservation of the pwm signal of red-green-blue respectively according to the color of touch-control layout setting; Give the LED driver module with the pwm signal duty cycle transmissions of these three kinds of colors respectively simultaneously, the LED driver module drives the color of three-color LED light with the layout setting of Show Color touch-control according to the pwm signal duty ratio of these three kinds of colors.
When the red-green-blue color configuration bar of user through color touch-control interface is provided with the color of liking; Touch arbitrary color that moves in the red-green-blue or the color configuration bar of appointing second colors or three kinds of colors of RGB; The color of oneself liking is set; The color control module is regulated the duty ratio and the preservation of the pwm signal of red-green-blue respectively according to the color of touch-control layout setting; Give the LED driver module with the pwm signal duty cycle transmissions of these three kinds of colors respectively simultaneously, the LED driver module drives the color of three-color LED light with the layout setting of Show Color touch-control according to the pwm signal duty ratio of these three kinds of colors.
Wherein, said PWM is Pulse Width Modulation abbreviation, and the Chinese meaning is exactly pulse width modulation, is called for short pulse-width modulation.It is to utilize the numeral of microprocessor to export a kind of very effective technology that analog circuit is controlled, and is widely used in measuring communication, many fields such as power control and conversion.
In the present invention; The color control module is through the drive current duty ratio of the pwm signal of control red, green, blue three primary colors; And then the brightness in various degree of control red, green, blue three colors changes; And, realize the multiple Show Color of front panel three-color LED through these three kinds of color collocation under different brightness.The redness configuration bar at said color touch-control interface has 256 kinds of colour brightnesses in various degree available, and green configuration bar also has 256 kinds of colour brightnesses in various degree available, and blue configuration bar also has 256 kinds of colour brightnesses in various degree available.When these three kinds of colors were configured, when being set to zero like the brightness of redness configuration bar, the drive current duty ratio of corresponding red pwm signal also was zero; When the brightness of green configuration bar was set to zero, the drive current duty ratio of respective green pwm signal also was zero; When the brightness of blue configuration bar was set to zero, the drive current duty ratio of corresponding blue pwm signal also was zero, and the color of front panel three-color LED light at this moment is shown as black.The brightness of and for example red configuration bar is set to 255; The brightness of green configuration bar is set to 255; The brightness of blue configuration bar is set at 255 o'clock, and the duty ratio of corresponding red pwm signal is 255, and the duty ratio of green pwm signal is 255; The duty ratio of blue pwm signal is 255, and the color of front panel three-color LED light at this moment is shown as white; The rest may be inferred, and the configuration of the colour brightness in various degree through these three primary colors can realize 16777216 kinds of colors.
Of the present invention one big advantage is the operation foolization, and the user only needs light one to touch the color settings function, gets into color touch-control interface; Follow one's inclinations and arbitrarily click color commonly used; But the color that the panel backlight is liked with regard to explicit user at once thinks that like the user oneself mixes colours, the arbitrarily pulling red-green-blue color configuration bar of also only need following one's inclinations; Just having 16777216 kinds of colors to be provided with voluntarily with the user selects; And display effect just is presented on the front panel backlight at once, like this, has greatly satisfied the user to the diversified demand of mobile unit front panel lamp Show Color.
