See also Fig. 1, be the circuit theory diagrams of forming the indicator light circuit of color tunable by the RGB three primary colors of the present utility model.The indicator light circuit of forming color tunable by the RGB three primary colors of the present utility model comprises integrated circuit controller chip U1, light-emitting diode D2, LED lamp current-limiting resistance R1, R4, R5, R6, I2C bus build-out resistor R2, R3, triode Q1, Q1 driving resistor R7, current-limiting resistance R8, LED0 pull-up resistor R9 and isolating diode D1.Light-emitting diode D2 is made up of three separate diode of RGB.Output LED1, the LED2 of circuit controller chip U1, LED3 are connected to light-emitting diode D2 indigo plant, green, red diode by LED lamp current-limiting resistance R6, R5, R4 respectively, output LED0 connects pull-up resistor R9 and Q1 driving resistor R7, the Q1 driving resistor R7 other end connects triode Q1 base stage, triode Q1 collector electrode connects current-limiting resistance R8, emitter connects isolating diode D1, and the isolating diode D1 other end connects LED lamp current-limiting resistance R1.Circuit controller chip U1SCL, SDA pin connect I2C bus build-out resistor R2, R3 respectively, and by I2C bus and television set master MCU communication.Circuit controller chip U1 also links to each other with shunt capacitance C1, C2, to play filter action.In the utility model execution mode, circuit controller chip U1 adopts PCA9632.
To be example, introduce the implementation procedure of forming the indicator light circuit of color tunable by the RGB three primary colors of the present utility model below at television set.In the utility model execution mode, television set master MCU writes register to circuit controller chip U1 and realizes that the level of its output LED0, LED1, LED2, LED3 changes or the PWM wave form varies of LED negative electrode, thereby the colour brightness that realizes the LED lamp changes.Because three kinds of colors of RGB of light-emitting diode D2 integrate, so when three kinds of colour brightnesses of R, G, the B of LED lamp changed, the integral color effect that it demonstrates will be followed variation.
Each signal is as follows in the level value and the waveform situation of different conditions:
Wherein, OFF: be expressed as closed condition, this signal pins is in off-state; Low: be expressed as low level signal, be defaulted as 0V; High: be expressed as high level signal, be defaulted as 3.3V; PWM: be expressed as pwm signal, a kind of square-wave signal of frequency adjustable, the acquiescence high level is 3.3V, low level is 0V.
The indicator light circuit of being made of color tunable the RGB three primary colors of the present utility model in the luminous implementation procedure of holding state light-emitting diode D2 is: television set was in holding state after alternating current powered on, at this moment+3.3V normally exports, + 5V is output not, circuit controller chip U1 can operate as normal, this moment circuit controller chip U1 SDA, SCL is subjected to the I2C Communication Control of main MCU, can read and write control to circuit controller chip U1 register, realize 1 of circuit controller chip U1,2,3,4 pin signals (are respectively LED0, LED1, LED2, LED3) level configuration.When LED0 is set to high level, drive triode Q1 conducting, like this+3.3V has been connected to the anode of light-emitting diode D2 by current-limiting resistance R8, isolating diode D1 plays buffer action, in order to avoid+3.3V seals in+the 5V circuit network; Simultaneously, the LED3 of circuit controller chip U1 is set to low level, so red LED diode R conducting of light-emitting diode D2, the red LED diode can be normally luminous, LED1, LED2 because of circuit controller chip U1 is high level simultaneously, so green and blue led diode ends, thereby red light is bright during the realization holding state.Based on this principle, because three light-emitting diodes of RGB of light-emitting diode D2 are independently, as long as so configure the level value of LED1, LED2, LED3, the state that needs bright lamp in the time of just can independently realizing standby, LED lamp such as redness, green, blueness, yellow, cyan, purple, white is luminous, and the big I of the resistance value of adjusting LED lamp current-limiting resistance R4, R5, R6 and current-limiting resistance R8 realizes the luminous of different bright-dark degrees.
Indicator light circuit luminous implementation procedure of light-emitting diode D2 in start process of forming color tunable by the RGB three primary colors of the present utility model is: main MCU receives start of start-up command relief main power source and output+5V voltage at the Standby state, main simultaneously MCU sends the I2C instruction after finishing various initialization action, register to circuit controller chip U1 carries out reasonable configuration, makes the output signal of LED0, LED1, LED2, LED3 independently adjustable: such as allowing it close output, output high level, output low level, output pwm signal.Can wherein one the tunnel be adjusted to some output separately to LED0, LED1, LED2, LED3, also can do configuration, depend on setting fully circuit controller chip U1 related register to several roads.
The indicator light circuit of forming color tunable by the RGB three primary colors of the present utility model realizes that start process LED lamp flicker principle is: after the start, it is low level that LED0 is set, Q1 ends, + 3.3V does not power to light-emitting diode D2, have only+5V powers to light-emitting diode D2, by current-limiting resistance R1 and isolating diode D1 light-emitting diode D2 is powered, behind the corresponding bit position that register is set, make LED1, LED2, LED3 be output as the OFF state, this moment, light-emitting diode D2 can't conducting, and LED is not luminous; When the corresponding positions that register is set make LED1, LED2, when LED3 is output as low level state, light-emitting diode D2 conducting this moment, LED is luminous, luminous color can be done relative set fully as required, such as needs white, then LED1, LED2, LED3 are simultaneously luminous, need red, green, blue monochromatic luminous LED1, LED2 can be set then, LED3 is independent output low level.The resistance that can regulate simultaneously LED lamp current-limiting resistance R1, R4, R5, R6 allows the monochromatic colour brightness of LED RGB produce difference, makes the color of combination change.In order to allow the bright dark variation of the luminous generation discontinuity of LED, time can arbitrarily be set, such as bright again 0.5 second in dark 0.5 second, can do time control by main MCU timer, 0.5 second timing guarantees that once to circuit controller chip U1 is done setting LED1, LED2, LED3 are output as above-described setting.Certainly, in order to realize above bright dark variation, also LED1 can be set, LED2, LED3 is the output of PWM waveform, when output PWM ripple is in high level, because light-emitting diode D2 has certain conducting voltage, this moment, light-emitting diode D2 can't conducting, just LED can't be luminous, and when output PWM ripple was in low level, the anode voltage of light-emitting diode D2 was enough to make its conducting, LED can be normally luminous, realized bright dark variation equally, wherein one tunnel output can be set, also can do configuration several roads, its bright inner room interval can be done setting to corresponding registers equally, can realize the 0.09Hz-24Hz frequency change.
The indicator light circuit of forming color tunable by the RGB three primary colors of the present utility model realizes that start process LED lamp gradual change principle is: based on above bright dark change procedure principle, LED1, LED2 are set, LED3 is output as the PWM waveform, to the PWM output frequency of circuit controller chip U1 scope can be set is 24Hz-6.25KHz, frequency surpasses after the 50Hz in theory, and human eye has glittered with regard to the bright back light of imperceptible LED lamp.But, under the situation of fixed-frequency, the bright dark degree that can regulate the LED lamp by the duty ratio (being the time of PWM wave height level and the ratio in whole cycle) of change PWM output waveform, thus realize the progressive formation that television set LED lamp shows.In this circuit, what drive because of PWM is the LED negative electrode, so when duty ratio was big, the LED lamp was dark more, duty ratio is more little, and LED is bright more, and duty ratio is asymptotic 0, and the LED lamp is the brightest, and duty ratio is asymptotic 1, and the LED lamp does not almost work.By the U1 registers group is done configuration, the PWM ripple that LED1, LED2, any one road output duty cycle of LED3 were changed, also can be to the PWM ripple of any several roads output duty cycle variation, and maximum can realize the brilliance control of 8 bit resolutions (256 grades of linearities are adjustable), it is adjustable to be that duty ratio can be set to 0-99.6%, like this, the LED lamp looks just an evenly linear brightness fade effect.Owing to can realize independent adjustable to each road output separately, so, when the PWM on each road duty ratio was transferred differently, its three paths of LEDs was just different because of the inconsistent illumination effect that combines of brightness, thereby had realized the diversity of the illumination effect of start process gradual change.
The LED display effect implementation procedure of indicator light circuit after start is stable of being made of color tunable the RGB three primary colors of the present utility model is: after start is finished, television set has just entered stable duty cycle, see in the process of TV the user this moment, leeway in order to select for the multiple LED lamp of user display effect provides following displaying scheme.In the custom menu of television set, be provided with LED_R, LED_G, three options of LED_B, LED_R, LED_G, LED_B all can be adjustable at 0-100, when the user is adjusted to 0, LED is not luminous in expression, when the user is transferred to 100, LED is the brightest in expression, and actual from the adjustment process of 0-100 in the custom menu is backstage master MCU at the duty ratio of the corresponding PWM output of the control U1 change procedure from 1-0.The user is whenever when adjusting LED_R, LED_G, LED_B colour brightness, just can see that integral color effect that LED shows is in continuous variation, till being transferred to the color of oneself liking, can preserve such color effects automatically at this moment, guarantee that still be that this color shows next time when starting shooting.In this way, the user can change the led color display effect of oneself liking at any time, and is ever-changing, very convenient.Such as, user even can turn off the indication of LED lamp, the luminous influence of LED when avoiding see TV night to human eye vision.
