Description of drawings
Fig. 1 is the structured flowchart of the led light source of Based Intelligent Control of the present utility model.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As shown in Figure 1, a kind of led light source of Based Intelligent Control comprises microprocessor, light intensity sensor, first led driver, first led array, second led driver and second led array; Light intensity sensor links to each other with microprocessor by the I2C bus; The one PWM output port of microprocessor links to each other with first led array by first led driver; The 2nd PWM output port of microprocessor links to each other with second led array by second led driver;
Described microprocessor adopts MN101EF52A type single-chip microcomputer; Light intensity sensor adopts the TSL2560 chip, and first led driver and second led driver all adopt the AN30888A chip.
Described first led array and second led array all contain 10 parallel branches, are serially connected with 10 LED lamp in each bar parallel branch.
The TSL2560 chip is a kind of light intensity-digital sensor, is used for converting light intensity to digital signal output, has direct I2C interface.
Led array is 10 string 10 and arrays; AN30888A is the high-brightness LED driver for the LED illumination.Have 2 kinds of light-modulating modes for PWM control or normal voltage.Operating voltage is from 3V-20V, and standby current has soft start/overvoltage protection/step-down and detects protective circuit below 10uA, except the LED illumination, also can be used for LED-backlit/general lightings such as LED flash of light/hand lamp.Main control chip (MCU) is microprocessor, adopts the 8bit of Panasonic single-chip microcomputer MN101EF52A, has 32KFlash, 1K RAM, TQFP32 encapsulation, inner 20MHz RC oscillator, when dispatching from the factory precision be calibrated to ± 1%, have four road PWM output.
Course of work explanation: light intensity sensor is gathered environmental light intensity and is referred to send to microprocessor, and microprocessor sends to led driver with the brightness of control led array, until the brightness that reaches expection according to light intensity value output pwm pulse.Open first led array earlier, if brightness does not still reach requirement, open second led array again, good energy-conserving effect.
