Abstract
The invention discloses a method for setting the brightness of an LED lamp by using on-off coding of a power switch. The method comprises the following steps of: embedding an intelligent controller 200 in a control circuit of the LED lamp, wherein the intelligent controller 200 uses an energy storage circuit 203 at a power supply part, so that the intelligent controller 200 can normally work within several seconds after an external power supply is powered off; meanwhile, arranging an external power supply power-off detection circuit 202; and after a power switch is switched on, rapidly powering on and off the switch once within 0.3-3 seconds to realize that the LED lamp is slowly brightened from darkness and is darkened front brightness after reaching the maximum brightness; and when the brightness of the lamp is suitable, rapidly powering on and off the switch once, powering off the lamp when the brightness of the LED lamp stops changing, wherein when the lamp is powered on next time, the brightness of the lamp is the brightness set last time. If not satisfy the brightness, a user can reset the brightness according to the operation steps. The method disclosed by the invention can realize LED lamp dimming conveniently and simply at a low cost.
Description
Technical field
The invention belongs to electronic technology field, relate in particular to and a kind ofly can realize the LED lamp
BrightnessThe method of adjusting.
Background technology
At present, generally can only carry out light modulation to incandescent lamp, need use a dimmer during light modulation, this dimmer typically uses the method that changes the silicon controlled angle of flow and realizes light modulation, the method light modulation is not suitable for fluorescent lamp and novel LED lamp, and memoryless and the variation function is set, can only lean on the stop of potentiometer mechanical location and mobilely realize memory and the variation function is set, can't adapt to advanced light-operated requirement.
Existing LED lamp light regulating technology mainly contains following two kinds of forms: one, realize with changing the method that flows through the LED lamp current value; Two, use change power supply PWM(pulse-width modulation) duty is recently realized.But these methods all need special equipment and circuit to realize; And the setting of LED lamp light modulation value, the simplest also the needs carries out with simulation potentiometer, digital regulation resistance, numeric keypad, remote controller, and this is so that common LED lamp light modulation complicated, cost is high and inconvenient.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide a kind of can realize convenient, simply, cheaply the light modulation of LED lamp encode to arrange the method for LED lamp brightness with the mains switch break-make.
Purpose of the present invention and solve its technical problem underlying and realize by the following technical solutions:
Of the present inventionly a kind ofly encode to arrange the method for LED lamp brightness with the mains switch break-make, may further comprise the steps:
(1) embed an intelligent controller in the control loop of LED lamp, this intelligent controller has partly used accumulator at power supply, so that dispatch from foreign news agency outage interior intelligent controller in rear some seconds still can work; Be provided with simultaneously the dispatch from foreign news agency power failure detection circuit;
(2) mains switch is opened, intelligent controller powers on, get the duty ratio of the brightness value control PWM of memory last time, lightening LED lamp, if power on first, putting brightness value is maximum and lightening LED lamp, and then intelligent controller arranges a timing in 0.3～3 second immediately, the open close phenomenon of power supply whether appearred in monitoring dispatch from foreign news agency power-off signal within 0.3～3 second timing phase, mains switch encoding setting state occurred then thinking to enter;
(3) this moment, intelligent controller began to adjust the duty ratio of PWM, so that the LED lamp is slowly entirely bright by secretly fading to, in its process, intelligent controller is monitored simultaneously dispatch from foreign news agency outage pin and the open close phenomenon of power supply whether occurred, if have, stop to change brightness, the duty ratio of memory PWM this moment is kept current brightness until outage; If occur to the open close phenomenon of complete bright still non-transformer, then control the LED lamp and slowly the open close phenomenon of power supply whether occurs by bright dimmed and monitoring dispatch from foreign news agency outage pin, by secretly brightening and monitoring the dispatch from foreign news agency outage, so circulation is until cut off the power supply to the darkest control LED lamp that transfers to again;
(4) if regularly the open close phenomenon of power supply do not occur in the phase at just powered on 0.3～3 second, then think normal behaviour in service, by the current brightness value LED lamp that maintainings lights.
Above-mentioned encode to arrange the method for LED lamp brightness with the mains switch break-make, wherein: intelligent controller is the MCU(single-chip microcomputer).
Above-mentioned encode to arrange the method for LED lamp brightness with the mains switch break-make, wherein: accumulator adopts large electrochemical capacitor or super capacitor.
The present invention compared with prior art, has obvious beneficial effect, by above technical scheme as can be known: in the control loop of LED lamp, embed the intelligent controller take MCU (single-chip microcomputer) as core, this controller partly used energy storage device (for example large electrochemical capacitor or super capacitor) at power supply so that after the dispatch from foreign news agency outage in some seconds MCU (single-chip microcomputer) still can work; In also being provided with simultaneously the dispatch from foreign news agency power failure detection circuit is arranged.After turning on the power switch, 0.3 quick on-off switch once in～3 seconds, the LED lamp is slowly by secretly brightening, again from bright dimmed iterative cycles, when lamp brightness was fit to, on-off switch was once fast again after the brightest, the brightness of LED lamp stops to change, turn off lamp, next time, the brightness of lamp was exactly to set last time when turning on light again.If dissatisfied this brightness can once reset by aforesaid operations again.Because each lamp all has brightness memory, can realize the brightness setting of a plurality of LED lamps with a mains switch, and this set is for lamp interior, thereby can realizes that light fixture is organized into groups with multiple light fixture splitter and light control.Only can make things convenient for, realize simply, cheaply light modulation with existing mains switch, because the present invention has realized the independent light modulation of each LED light fixture.Thereby so that get both when grouping control and light modulation.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
