Embodiment
The remote control thereof of LED decorating lighting lamp of the present invention comprises that signal emission process and signal receive two big processes, radiating portion uses microprocessor (MCU) or dedicated IC chip produces coding or random controling signal, and be provided with outer simulation electric quantity signal input interface and default remote control coding signal data storer, adopt multiple control mode to handle and generate infrared remote control signal through function selecting; Receiving unit is used embedded microprocessor (MCU) and is carried out computing and processing, with digital form production burst width control signal, control the break-make and the size of blue (B) three primary colours electrode of red (R) green (G) working current of each light emitting diode respectively with the switch on and off time scale signal, realize lamplit Digital Control.Can bring into play the advantage and the strong point of semiconductor illuminating light source so to greatest extent, build a colorful dynamic lighting atmosphere that is rich in individual character, reach the illuminating effect that the traditional lighting means can't realize.
The principle of signal emission part of the present invention as shown in Figure 1, the critical piece that relates to comprises: keyboard matrix 1, microprocessor 2 (MCU), infrared diode transmitter 3, LCD display 6 and emission power 4.Keyboard matrix 1 is used to import remote signal, and microprocessor 2 produces coding and modulates, again by infrared diode transmitter 3 emission infra-red code signals.Radiating portion is because power consumption is small, and emission power 4 uses dry cell; Keyboard matrix can adopt 4 * 4～8 * 8 specification, and concrete quantity is determined according to the needs of control function; LCD display 6 is used for the content of operation of presentation control function.Microprocessor 2 also is connected with data-carrier store 7, is used for storing predetermined remote control coding signal.
Remote signal is mainly produced by keyboard matrix 1, can also an external signal input interface 5 be set at the infra-red remote control radiating portion, be used to import simulation electric quantity signals such as various external parameters such as language, music, after process microprocessor 2 carries out the A/D conversion, also become remote signal and be launched away.So just can implement external control, and can produce special sound effect light the color and the brightness of LED decorative illumination lamp.
Hobby according to the user, infra-red remote control transmitter also is provided with the random signal selection key, and the remote signal that random number code generates is after the receiving unit processing, with forming the unforeseen bizarre and motley color of people, can give people with huge visual impact.
MCU coding can adopt some binary code serial code of width modulation, and wherein the leading portion of information partly is a user identification code (preamble code), can distinguish different electric equipments, prevents that other remote control mode of variety classes from crosstalking mutually; Interlude partly is an operational code (function code); Back segment partly is typically designed to the radix-minus-one complement of operational code, is used for the correctness of verification operation sign indicating number.The binary code of remote signal generally will carry out secondary modulation through the carrier frequency of 38kHz, to increase antijamming capability and to improve emission efficiency, reaches the purpose that reduces power supply power consumption.After the secondary modulation, produce infrared ray to spatial emission by infrared-emitting diode again.
Fig. 3 is an infra-red remote control receiving system schematic diagram, comprises infrared receiver diode 11, light/electric switching amplifier 12, embedded microprocessor system composition.Microprocessor is formed according to minimum system, comprising microprocessor 10, electronics erasable memory 13 (EEPROM), output expansion module 14 and timing time block 15.Light-emitting procedure is stored in the electronics erasable memory 13 (EEPROM), injects data by the telechirics infrared transmitter.Regularly timing module 15 provides time reference and time reservation for the infra-red remote control system.The present invention relates to the LED light fixture of the conduct decoration or the arbitrary shape of lighting source, various styles, use the quantity of high-power three-color light-emitting diode many, be necessary to be provided with output expansion module 14, its control port is connected to several pulse width generation modules 16, respectively with all light emitting diodes 18/1,18/2 of interior decoration lighting ..., 18/n blue (B) three primary colours electrode of red (R) green (G) connect, AC/DC translation circuit 17 makes civil power be transformed into low-voltage DC 19 and supplies with microprocessor system and all light emitting diodes of interior decoration illuminating lamp.
Light emitting diode is exactly still can keep its luminous efficiency and optical color parameter in bigger drive current range as outstanding feature of lighting source, and the present invention adopts the pulse width control mode that whether luminous the and luminous intensity of LED source controlled.When current lead-through, lumination of light emitting diode, luminous intensity is controlled by pulse width.In a work period, pulse width has determined the time of led current conducting, and the time scale of conducting is big more, and is big more by average led current in the work period, and lumination of light emitting diode intensity is just strong more.For 8-bit microprocessor (MCU) commonly used, range of control is 28, and lamplit Digital Control scope is reached 256 grades of briliancy, and promptly 0-255 is equivalent to binary number 00000000-11111111, and full scale is 256.That is to say that when the scale-of-two control data was 00000000, the time scale of conducting was 0/256 in the work period, the pulse width of generation is 0, and light emitting diode is not luminous; When the scale-of-two control data was 11111111, the time scale of conducting was 255/256, and the pulse width of generation is 255/256 of the cycle, and average current is near maximal value, and light emitting diode almost sends maximum luminous intensity.Like this, can control the break-make and the size of RGB three electrode currents of each high-power three-color light-emitting diode easily by digital form, led light source is luminous, glow color and luminous intensity, is all controlled by the microprocessor (MCU) of infra-red remote control receiving end.Because people's eye storage characteristic, in order to obtain stable illumination, the repetition frequency of microprocessor output control pulse can not be lower than 50 hertz usually.
Technical solution of the present invention is applicable to the LED decorating lighting lamp of arbitrary shape, various styles, and the three-color light-emitting diode of, high brightness high-power more than the 1W for using has popularizing value especially as the occasion of lighting source.
