Detailed description of the invention
With specific embodiment, the utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, in the present embodiment, wireless communication module uses bluetooth communication module, the present embodiment also includes: central processing module, PWM light-adjusting module, clock module, the first supply module and the second supply module being connected with central processing module respectively, constant voltage source is i.e. dimmed driving module and powers to PWM light-adjusting module by the first supply module, is powered to central processing module by the i.e. central processing unit supply module of the second supply module.Clock module is connected with central processing module to obtain timing function；Bluetooth communication module is connected for receiving dimming commands with central processing module；Dim the input voltage driving supply module to be connected to adjust PWM light-adjusting module with constant voltage source；Central processing unit supply module with light modulation drive supply module be connected with adjustment central processing module input voltage；PWM light-adjusting module is connected with central processing module to obtain dimming function；Signal conversion module is connected with central processing module for pwm signal being converted into direct current signal to play the purpose preventing LED from flashing dutycycle is relatively low when.
As shown in Figure 2, the light modulation principle of LED blue-tooth intelligence controller is: light modulation drives the 12/24V voltage that export by constant voltage source of supply module through the LDO(low pressure difference linear voltage regulator of LED blue-tooth intelligence controller) be converted to 12V voltage and be powered to central processing unit supply module, it is that central processing module is powered that 12V voltage is converted to 3.3V voltage by LDO by central processing unit supply module, bluetooth communication module on central processing module receives the control signal of the handheld device input supporting bluetooth 4.0 function and is sent to central processing module, 43 pins of central processing module connect PWM light-adjusting module, 32 pins of central processing module connect signal conversion module.
Pwm signal is exported to PWM light-adjusting module by 43 pins of central processing module, during 43 pin output high level (+3.3V), electric current is by after current-limiting resistance R10, make NPN type triode Q6 base potential higher than emitter stage current potential, triode Q6 turns on, colelctor electrode one resistance R9 of pull-up of triode Q6, therefore the voltage VCE=0V between triode Q6 collector and emitter, triode Q7 is PNP type triode, VBE < 0V due to the voltage between triode Q7 base stage and emitter stage, therefore triode Q7 conducting, now metal-oxide-semiconductor (field-effect transistor) Q1, Q2, Q3, the gate source voltage of Q4 is 0V, 4 metal-oxide-semiconductor switches cut out, LED load is closed；During 43 pin output low level, triode Q6 is not turned on, now triode Q5 conducting, Q7 is not turned on, and+12V voltage makes NPN type triode Q5 turn on, and electric current flows to resistance R11, simultaneously driving 4 metal-oxide-semiconductors in parallel again, 4 metal-oxide-semiconductors open switch simultaneously, and LED load is opened.The effect of 4 metal-oxide-semiconductor parallel connections is to increase output electric current, and resistance R5 and diode D2 in parallel and resistance R6 in parallel and diode D3, resistance R7 in parallel and diode D4, resistance R8 in parallel are acceleration electric discharges with the effect of diode D5, balanced discharge.The regulation that PWM light-adjusting module realizes LED average current by wave chopping technology controls, persistence characteristic according to human eye, can be the regulating frequency that human eye cannot be perceived the frequency setting of PWM light modulation, by changing PWM duty cycle, realize the light modulation output of LED load, thus realize LED load brightness control function.Central processing module can read the time of external clock module and contrast with the current setting time, thus reaches the function of timing dimming output.
