Description

Programmed control multifunction stepless colour changing lamp

The utility model belongs to daily technical field of lighting fixtures, particularly a kind of novel color lamp and combination thereof.

Color lamp is widely used in noon platform, open entertainment place, and among restaurant even the family, motley light has increased living color, gives beautiful enjoyment.The at present general color lamp that uses is made up of versicolor lamp, by control different colours lamp bright, go out, reach the purpose of color change, so the color of light is limited, its change color is dullness also.

The purpose of this utility model is to design a kind of novel color lamp for overcoming the weak point of above-mentioned lamp group colour, and its light coloring is changed continuously, and the combination of many color lamps produces diversified color change style, to satisfy the pursuit of people to U.S..

The utility model is designed a kind of Programmable Multifunction stepless colour-changing lamp; it is characterized in that adopting red, green, blue three primary colors monochromatic bulb with placing among the lampshade; said every kind of monochromatic bulb and one drives, and protective circuit connects, and links to each other with the different mouthfuls of lines of CPU respectively.Control the brightness of each monochromatic bulb, then can form the different colours ratio, thereby objectively produce shades of colour.Operation principle of the present utility model is summarized as follows: the PWM pulse width modulation mode is adopted in the control to each bulb brightness; be that CPU exports three row same frequencys from three mouthfuls of lines; but the modulation wave signal of change width; driving, protective circuit that control is connected with every kind of bulb; make to be added in three kinds of average voltage level on the monochromatic bulb and to change, thereby the brightness of every kind of color of lamp is changed.Reach the effect of stepless colour-changing.

The utility model can be combined above-mentioned many stepless colour-changing lamps, and links to each other with the different mouthfuls of lines of CPU, by the control program of prior establishment, control the color of every lamp, the variation of brightness can produce numerous color styles, as the gradual change of color, saltus step, flowing water, acoustic control saltus step etc.

The utility model not only can be used for home decoration, and can be widely used in public, amusement, performs various occasions, and the variation of its light coloring can be set style and change flexibly in advance according to different occasion requirements, and control is convenient, is with a wide range of applications.

The utility model provides a kind of embodiment of Programmable Multifunction stepless colour-changing lamp, be described in detail as follows in conjunction with Fig. 1～Figure 10: Fig. 1 is lamp interior structural representation of present embodiment, visible stepless colour-changing lamp is the garden disk shape among the figure, go up 6 bulbs that evenly distribute in one garden week of lamp chassis, its color is by the green sequence arrangement of red orchid, and the outside is covered a lampshade again.Every kind of color bulb of this lamp all drives with one; protective circuit connects, and driving, protective circuit add one-level before the single channel power promotion output employing VMOS pipe and follow driving as shown in Figure 2; preposition employing optocoupler and CPU board are isolated, and the VSS ground wire is following to be current foldback circuit.The 0.2 Ω resistance of connecting with the VMOS pipe is sample resistance, and lamp group power supply obtains after rectification with civil power.The overcurrent protection course of work is: when the VMOS tube current raises; the sample resistance pressure drop increases; when reaching limit value; triode BG1 conducting, thus make also conducting of triode BG2, and the BG2 conducting can make the further conducting of BG1 again conversely; be that both have formed positive feedback; the both is in conducting state once triggering then, thereby BG2 drives optocoupler and is conducting state, makes the VMOS pipe be in the state of blocking to reach the protection purpose.

The drive circuit of three kinds of color bulbs is respectively the P1.0 that is connected to CPU, P1.1, P1,2 three Tiaokou lines, CPU exports three row same frequencys to three Tiaokou lines, but the modulating wave of change width, this three train wave adopts timer 0 and timer 1 time-delay counting, to P1.0, and P1.1, P1.2 regularly exports 0 or 1, forms three train waves.CPU board basic configuration and operation principle are as shown in Figure 3.CPU board adopts 8031AH, 74LS373 address latch, 27128 memory under programs, the 3P toggle switch connects Senior Three bit address line, can be used to select different blocks, this CPU board INTO, INT1, P3.5, P3.1, P3.4 is as the key function selecting, CPU is provided with 4 function keys, and key 1 is a working mode selection, and key 2 is a work stoppage, key 3 is the pace of change that slows down, and key 4 is for accelerating pace of change.The acoustic control input is received in the sound control circuit output.Sound control circuit is divided into level Four as shown in Figure 4, and first order triode is a follower, and filtering and amplification are played in the second level, only get the drumbeat signal, and the 3rd, level Four is an amplifier, 100 μ electric capacity are the usefulness of filtering.

The utility model provides with above-mentioned nine Color-changing lamps combination, produces the color change of multiple sample with the CPU program control, and nine mouth lines of nine lamps and CPU are connected, and are divided into three the tunnel, and as shown in Figure 5, three tunnel independences mutually can have different variations separately, also can cooperatively interact.Fig. 6～Figure 10 is the program flow diagram of present embodiment, wherein Fig. 6 is a basic flow sheet, the first initialization T1 in back the steps include: to power on, the T0 timer, by timer T0 generation-250Hz square wave: open 1NTO, INT1 interrupt (enter first kind of mode wash rice automatically and become mode) to be waited for and interrupting: T0, T1,1NTO, INT1).

Fig. 7 is an INTO interrupt service routine flow chart, the steps include: to judge that P3.5=0 not, is, then suspend, and or not that then the mode of carrying out is switched.

Fig. 8 is an INT1 interrupt service routine flow chart, the steps include: to judge whether P3.1 is 0, is 0 and adds 5DH, pace of change slows down, returning then, is 1 o'clock, judges then whether P3.4 is 0, be then to subtract 5DH at 0 o'clock, accelerate pace of change, return then, judge that 7BH is not 1 not if P3.4 is 1, if 1 is jumped to the 4th kind of state, if 7BH is 0 and returns.

Fig. 9 is a TO interrupt service routine flow chart, the steps include: to judge whether 5FH-1 is 0, if then with P1 mouth and P3.0, return after clear 0,, then 30H～38H is subtracted 1 respectively if be not 0, and judge whether to be 0, and be 0 and respectively corresponding with it each mouthful line put 1 operation, return then.

Figure 10 is a T1 interrupt service routine flow chart, the steps include: that 5EH-1 is not 0 not, is not then to return, be to judge that then 7FH is not 1 not, if 0, then judge 7EH, 7EH is the free position saltus step mode that entered in 1 o'clock, 7EH is 0 o'clock, enter gradual manner, 7FH is 1 o'clock, and then 7EH entered the acoustic control state at 0 o'clock, 7EH is 1 o'clock, enters seven look transitional states.
