Below various functions are described in further detail

1, opening/closing function

The remote control receiving terminal will be received " ON/OFF " (being encoded to " the 1000 ") signal from remote controller when by the button of " ON/OFF " of movement controller, and microprocessor will judge in advance that existing state is " ON " or " OFF ".Then it is changed into when current state is " ON " " OFF ", the trigger impulse of microprocessor output after this prolongs after will be progressively, even the silicon controlled angle of flow progressively reduces, until being zero.Its actual effect is that the brightness of controlled illumination lamp progressively reduces, until extinguishing.Meanwhile, indicator light also extinguishes.Otherwise, if current state then changes it into " ON " when being " OFF ", simultaneously, indicator light is lighted, the trigger impulse of microprocessor output will progressively before push away, the silicon controlled trigger angle progressively increases thereupon, and the brightness of controlled illumination lamp is started from scratch progressively to be increased, till current brightness settings.

Click hand push button (0.05＜turn-on time＜0.35 second), its effect is identical with the button effect of " ON/OFF " that press remote controller.

2, circulation dimming function

Current state at the controlled illumination lamp is under the state of " ON ", presses hand push button greater than 0.35 second, and microprocessor will detect this signal and be judged as " circulation light modulation " through function requirement analysis module.After this, microprocessor military order triggering and conducting angle by progressively become big-maximum-progressively diminish-minimum-progressively become big rule to change, so move in circles.During this period, indicator light is with ceaselessly fast blink.After entering " circulation light modulation " state, as long as button does not unclamp, this circulation light modulation just continues always.After button unclamps, the brightness of this moment will keep and preserve as current brightness settings.At this moment, indicator light recovers Chang Liang.

Can make light modulation more convenient and quick because use a teleswitch, so when remote control mode, there is not to be provided with corresponding with it function.

3, brightness increase/brightness reduces function

Have " INC " (being encoded to " 1100 ") (brightness increase) and " DEC " (being encoded to " 1010 ") (brightness minimizing) function at remote control mode, when the remote control receiving terminal is received " INC " signal from remote controller, a microprocessor military order trigger impulse reach unit (the increase angle of flow) also upgrades current brightness settings simultaneously again.If the angle of flow has reached maximum, then the angle of flow will remain unchanged, and export a prompting sound simultaneously.In like manner, when the remote control receiving terminal is received " DEC " signal from remote controller, move a unit (reducing the angle of flow) behind the microprocessor military order trigger impulse, also current brightness settings is upgraded again simultaneously.If the angle of flow has reached minimum value, then the angle of flow will remain unchanged, and export a prompting sound simultaneously.

Manual operation does not support brightness increase/brightness to reduce function.

4, the brightest/the darkest (light modulation fast) function

Current state at the controlled illumination lamp is under the state of " ON ", when the remote control receiving terminal is received " MAX/MIN/BELL " (being encoded to " 1011 ") signal from remote controller, microprocessor will judge in advance whether existing brightness is " the brightest ", be then it to be changed into " the darkest ", move after progressively with seasonal trigger impulse, upgrade simultaneously to the minimum set point brightness of controlled illumination lamp (this moment for the darkest) and with existing brightness value until the angle of flow; As not being, then change existing brightness into " the brightest ", progressively move forward to the maximum brightness of controlled illumination lamp (this moment for the brightest) and existing brightness value is upgraded simultaneously with seasonal trigger impulse.In sum, whenever receive " MAX/MIN/BELL " signal, the operating state of this IC will replace change between " the brightest " and " the darkest ".

Manual operation only can realize the brightest function.Current state at the controlled illumination lamp is under the state of " OFF ", press hand push button and keep (greater than 0.35 second), microprocessor will be turned on controlled illumination lamp (changing current state into " ON " by " OFF ") this moment, progressively increase until maximum (corresponding brightness is for the brightest) from minimum with seasonal triggering and conducting angle, and this is preserved as existing brightness value, indicator light also will become Chang Liang from extinguishing.

5, delay time～slowly close (SLEEP_OFF, i.e. sleep is turned off the light) function

This function and the people requirement when entering sleep matches.When receiving terminal is received " SLEEP " (being encoded to " 1101 ") signal from remote controller, when current state be " ON " simultaneously, (SLEEP_OFF) function delay time～was slowly closed in execution.At this moment, microprocessor is with first line delay a period of time, and during this period, indicator light will glimmer at a slow speed.After time-delay finished, microprocessor will be lentamente moves trigger impulse after successively, until being zero.Meanwhile, the indicator light flash speed is accelerated, and the brightness of controlled illumination lamp is slowly deepening synchronously also, until extinguishing.And the current state of illuminating lamp also will be changed into " OFF " by existing " ON ", and indicator light also will extinguish simultaneously.

Manual operation also can realize this function.When current state is " ON ", double-click hand push button at the controlled illumination lamp, enter immediately to carry out and delay time～slowly close (SLEEP_OFF) function.

6, slowly open (SLEEP_ON, i.e. sleep is turned on light) function

When people awake from sleep, often think that the light that throws open is dazzling extraordinarily, design in order to address this problem and slowly open (SLEEP_ON) function.Receive " SLEEP " signal when receiving terminal, when current state is " OFF " simultaneously, will enters slowly and open (SLEEP_ON) function from remote controller.During this period, indicator light will be with the flicker of speed extremely slowly, simultaneously microprocessor make the triggering and conducting angle from zero degree begin with the utmost point lentamente speed increase successively, the brightness of corresponding illuminating lamp also with the utmost point lentamente speed progressively increase, reduced stimulation to human eye.The brightness that this process continues up to light arrives till the set point.This moment, indicator light reverts to normal bright state.

Hand push button does not support slowly to open (SLEEP_ON) function.

7, sound-light prompting function

For each effective operation, this IC all can provide corresponding sound (if auditory tone cues is allowed to), light index signal, makes the operator know what's what.More than each part when carrying out functional description, also light index signal (LED light) has been carried out corresponding explanation, just repeat no more herein.Here main permission/prohibiting function with regard to operation indicating sound is described: power up first, voice prompt function will be set to " permission " automatically.After this, whenever receiving terminal is received various useful signals from remote controller (exception when its brightness does not reach " the brightest " or " the darkest " when receiving " INC " or " DEC " signal) or detected the valid function of hand push button, microprocessor all will be exported a string short pulse by the terminal (2) of IC, and the buzzer that receive on this terminal this moment will send an of short duration prompting sound.When the operating state of IC is under the situation of " OFF ", if receiving terminal is received " MAX/MIN/BFLL " signal from remote controller, microprocessor will think that this is a valid function to the permission/prohibiting function of auditory tone cues, and operation sequence will enter the prompting sound control module.If auditory tone cues is allowed to this moment, then will forbid it; Otherwise, then be allowed to, so move in circles.Before the next one arrives to the valid function of the permission/prohibiting function of auditory tone cues, microprocessor will keep present state constant.

Hand push button is not supported the operating function of the permission/forbid to auditory tone cues.
