Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment:
LED is light emitting semiconductor device, and the power supply used is constant-current source, constant-current source and voltage source different, electric current is constant, voltage be but change.
As shown in Figure 1 and Figure 2, a kind of LED tunable optical power module with Radio Control Function, 220V can be realized to exchange turn 5V and two-way can the function of controlled in wireless constant current output.This power module comprises AC front input module, AF panel module, full-wave rectification block, lightning surge absorption module, PFC prime input module, the active PFC constant current driving mould of Dimmable LED and 5V supply module.
Alternating current (85Vac--264Vac) enters AC front input module through illuminating line, first through fuse (FUSE), after piezo-resistance (VR1) process, through AF panel module (1/CX1,1/CX2,1/R9,1/R10,1/L5), carry out rectification (1/DB1) by rectifier bridge, now ac voltage rectifier is become high voltage direct current by four rectifier diodes by AC alternating current, then by lightning surge absorption module (1/D1,1/R1,1/R2,1CE3).
AF panel module is used for EMI filtering, the noise controlling electric network noise and self produce, the wherein voltage of bleeder resistance 1/R9 and 1/R10 after shutdown of releasing on electric capacity 1/CX1 and 1/CX2, electric capacity 1/CX1 and 1/CX2 is for eliminating differential mode interference, and common mode inductance 1/L5 is for eliminating common mode disturbances.Lightning surge absorption module is used for suppressing the residual amount of energy that produces afterwards in thunderbolt of power-supply system.
Busbar voltage (voltage being often referred to the initial linkage section circuit of the power supply output with numerous branch is called busbar voltage) after rectification module and lightning surge absorption module, first through power factor prime module (1/L3,1/C1,1C2 and correlated parts) after EMI filtering, enter the active PFC constant-current driven module of first and second Dimmable LED (2/U1,3/U1 and correlated parts), by high-pressure pulsating DC chopped-wave and convert to load need power drive rear end LED module.
IC (2/U1,3/U1) driving power field effect transistor 2/Q1, makes the half-wave sinusoidal voltage after the peak current envelope following rectification of its conducting realize power factor correction; The average current flowing through inductance 2/L4 during 2/Q1 conducting is the electric current passed through in LED, and the effective value of this average current is constant in certain error, realizes LED constant current.By the duty ratio of regulating power pipe Q, forcing input current to follow the tracks of input voltage is sinusoidal waveform change.Because input voltage is current waveform in full-wave rectifier, containing abundant harmonic wave, therefore current regulator must have enough bandwidth, makes input current follow the tracks of full-wave direct current voltage reference.In order to obtain the good control of electric current and good dynamic characteristic, electric current loop must be higher low-frequency gain, wider frequency band.
The light modulation pin outer (PIN7) of 2/U1,3U1 adds a RC network (2/R12,2/CM, 3/R12,3/CM) and PWM dim signal is shaped to a mean value (0.7V to 3.5V), realizes the light modulation from 10% to 100%; Voltage is larger, and LED current is larger; When voltage drop is to 0.7V, switching tube turns off, and driver output electric current is zero.
Adopt single-stage buck formula APFC in the active PFC constant-current driven module of Dimmable LED, input current is improved, distortion degree reduces, thus the power factor of circuit is improved, and has that circuit is simple, low cost and other advantages.The basic definition of power factor PF refers to the ratio exchanging active-power P and apparent power W, Active Power Factor Correction increases a power conversion circuit between the rectification circuit and output capacitance of load, input current is corrected to input voltage synchronous sine wave, thus PF is improved.Meanwhile, single-level power factor converter has following advantage: 1) derailing switch number of packages reduces, and main circuit volume and cost can reduce; 2) control circuit only has an output loop usually, simplifies control loop; 3) in single-stage converter topology, portion of energy can be directly delivered to outlet side, without Two Stages, so efficiency is higher than 2 stage converter.Due to above feature, advantage is clearly in middle low power LED driver for single-stage power factor correcting circuit.
In brief, illumination alternating current, by rectification, realizes the power supply process that power factor correction realizes constant current simultaneously, achieves the driving of LED module.
Simultaneously, operationally obtained the voltage maintaining IC work from auxiliary winding by self-excitation according to active PFC constant current conversion IC, now this is used, the winding separating 5V pulse and need is assisted winding power (15VDC) from 3/U1, by 3/D6 rectification, after 3/C7,3/C8 filtering, realize 5VDC and go to execution control module in LED tunable optical system and communication module is powered.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
