The specific embodiment
Fig. 1 is the fitting structure block diagram, among the figure: 1 is power module, 2 is red, green, blue three primary colours large-power light-emitting diodes, and R-LED is red, and G-LED is green, B-LED is blue, 3 is the control model selected cell, and 4 is user input unit, and 5 is analog quantity/digital quantity (A/D) conversion unit, 6 is microprocessing unit, and 7 is the diode driver element.
Fig. 2 is the lamp circuit principle schematic, and the two ends of toggle switch are connected respectively to low level and high level, and when the I/O mouth of single-chip microcomputer 6 was arrived in toggle switch input 1 (or 0), the mode of operation of light fixture was manual color adaptation pattern; During input 0 (or 1), the mode of operation of lamp is a stochastic model.The two ends of potentiometer are connected respectively to low level and high level, the middle-end of potentiometer is connected to the pin that mould/number transforms chip 5, INO for example, whether control this pin input by address input control end effective, for present embodiment, ADDA, ADDB and ADDC are three address input control ends, and when it all was low level, the INO input effectively.The conversion enabling signal pin START of mould/number conversion chip 5 is connected to an I/O pin of single-chip microcomputer 6, and by driven by program, concrete control flow is referring to Fig. 3 by single-chip microcomputer.EOC is that A/D transforms the end mark position, is input to an I/O mouth of single-chip microcomputer 6, after single-chip microcomputer detects A/D conversion end, conversion results is input to eight I/O mouths of single-chip microcomputer by digital quantity output D0-D7.The data output that mould/number transforms chip 5 allows control pin OE (or controlling the chip selection signal pin CS whether A/D works) to be connected to an I/O pin of single-chip microcomputer 6, is transformed the data output of chip by Single-chip Controlling mould/number.Three I/O pins of single-chip microcomputer 6 are connected respectively to three input pins of 74LS04 not gate integrated chip 7.Three output pins of not gate integrated chip connect the negative electrode pin of red, green, blue three primary colours large-power light-emitting diodes R, G, B respectively, because the electric current of large-power light-emitting diodes is very big, the present invention is total to lighting of sun control light emitting diode by not gate.Light emitting diode R, G, the B of three kinds of colors of said red, green, blue accept the pulse that 74LS04 not gate integrated chip is sent here, light with the time in sequence, thereby make light fixture send different colors.
The connected mode of above-mentioned module and other pin of chip is connected according to the known connected mode of this device, for example, the CLK of analog quantity/digital quantity conversion unit is the working pulse that A/D transforms, and can be obtained through frequency division by a control pin CTNLO of single-chip microcomputer or independent CLK source input.
Fig. 3 is the control program schematic diagram of light fixture, carries out initialization after the start: dummy order, and give symbol in the source program to indicate, STAR EQU P3.0 for example, EOC EQU P3.1 etc.; Carry out pattern then and judge, the value of sending here according to toggle switch is that 0 or 1 decision enters manual color adaptation pattern or stochastic model.As enter manual color adaptation pattern subprogram, at first carrying out A/D transforms, the analog quantity of potentiometer output is converted into digital quantity, by the digital quantity that is converted table look-up can obtain the three primary colours large-power light-emitting diodes light the time that (table is obtained by the gradual change algorithm, algorithm is to get according to several color model, this process can be according to the prior art programmed, handle by single-chip microcomputer), light red, green, blue three primary colours large-power light-emitting diodes successively according to the time of lighting, the pattern that enters is once more judged state after lighting end, so circulation.As enter color stochastic model subprogram, produce two eight pseudo random numbers, (one of them was tabled look-up and obtained lighting the time of three primary colours large-power light-emitting diodes the time of lighting of corresponding respectively three primary colours large-power light-emitting diodes and the duration of this color, the duration of the corresponding this color of another one), light the three primary colours large-power light-emitting diodes successively according to the time of lighting, show a kind of random color; Whether the duration of judging color arrives, and is less than then to continue to show this color, to then entering pattern judgement state once more, so circulates.
Under manual color adaptation pattern, by the different analog quantity of rotational potentiometer knob input, after process ADC0809 chip is converted into different digital quantities, give the P1 mouth of single-chip microcomputer, single-chip microcomputer calculates the red of correspondence, green, the blue three-color large-power light-emitting diodes light the time after, from P0.0, P0.1, the P0.2 mouth is sent corresponding pulsewidth, light the diode of three kinds of colors successively, the time of lighting of light emitting diode is all in the microsecond level, much smaller than 0.05 second to the 0.2 second retentivity time of eye of human eye, be red because the visual persistence observer of human eye sees, green, a kind of color that blue three-color mixes out.A kind of duration of color, in the decision of the time of staying of a certain position, when potentiometer maintained static, color remained unchanged by potentiometer, and when manual rotational potentiometer, color produces respective change.Potentiometer rotates a circle, and the color of lamp gradually changes, and the purple and optional intermediate color wherein of the yellowish green ultramarine of experience blood orange has almost contained the discernible all colours of human eye.For example: when the voltage of potentiometer input is 0V, be 0 after transforming through A/D, look into R, G, B lights timetable and obtains 255,0,0, and is shown in red.
Under stochastic model, constantly produce a pair of by a pseudo random number program to random number, lighting the time of first corresponding three primary colours large-power light-emitting diodes wherein, the duration of a kind of color that three kinds of blend of colors of second corresponding red, green, blue are come out.Lamp is the automated randomized change of color meeting under the control of single-chip microcomputer, a kind of time of lighting of color can be the random number between 0.5 second to 2 seconds, be that the observer had not both known that next carves lantern festival was for what color, do not know also how long this color can continue, give the sensation of a kind of magic romance of people.
A kind of duration of color (promptly simulating the time that potentiometer stops in each position) can be set at the random number (random) between 0.5 second to 2 seconds, for example, 0.5, (the random number random that obtains was 0-255 in 0.6,0.8,0.9,1.0,1.2,1.4,1.6,1.8,2.0 second, add 1 back and be 1-256,0.5+1.5*random/256 can obtain the time of lighting).
The toggle switch middle-end connects single-chip microcomputer P3.5 mouth, and both sides connect low level and high level respectively, single-chip microcomputer inquire about the P3.5 mouth in the work period of each microsecond level state once, thereby the switching between the realization two states.
The invention has the beneficial effects as follows: gradually change once, color that only potentiometer knob can the manual adjustments lamp, and color contained the discernible all colours of human eye, used large-power light-emitting diodes low in energy consumption, good reliability, life-span are long; Two, realize the color of lamp and light time arbitrariness at random, given its dreamlike color.
In the above-mentioned light fixture, the light emitting diode of three kinds of colors of red, green, blue should be lighted successively, the diode of three kinds of colors is lighted the time sum and is not more than human eye vision and persists 0.05 second to 0.2 second time in each ignition period, can produce color changeable effect preferably, as a kind of specific embodiments, the present invention sets it and is not more than 0.02 second, and for example, 0.02 second, 0.015 second, 0.01 second, 0.005 second etc. all is the scheme that can select.The color that presents be the light emitting diode of three kinds of colors of the red, green, blue ratio of lighting the time (prerequisite is that the three lights the time sum and is not more than 0.02 second in the one-period), for example, the ratio R that lights when the diode of three kinds of colors: G: B=1: in the time of 0: 0 for red, as R: G: B=0: be green in the time of 1: 0, as R: G: B=0: be blue look in the time of 0: 1, as R: G: B=1: be white in the time of 1: 1, as R: G: B=1: be yellow in the time of 1: 0, as R: G: B=1: be purple in the time of 0: 1, as R: G: B=0: be cyan in the time of 1: 1.The diode of two kinds of colors is lighted simultaneously and is not worked, its blend color does not have any difference, key issue is that the interior three of one-period (the three primary colours large-power light-emitting diodes is lighted the time sum successively) lights the ratio of time, if both or three are simultaneously bright sometimes, good in theory, but in fact bring new problem: the power of system changes, and the brightness of lamp changes, and brightness influences color in a way, and display effect can degenerate; Some surpasses 1W constantly power, and the power of power module 1 should strengthen, and for example is increased to 2.5W (if having only at most two lamps simultaneously bright) or 5W (if having three lamps simultaneously bright) from 1.5W, and cost increases and effect is not improved.
The present invention can have 256 kinds of colors, lights time scale to 256 groups of R, G, B should be arranged, and they utilize color model to make a table.Under stochastic model, produce two random numbers earlier, the sequence number of first corresponding array (just R, G, B light the time, corresponding a kind of color), second random number correspondence continues to present the time of this color.The scheme that the light emitting diode of certain color correspondence is lighted the time gradual change can design according to Mathematical Modeling of the prior art, and for example the scheme that can adopt has:
1. cube color model
As shown in Figure 4, with RGB is in the unit cube of reference axis, lighting the time of corresponding three fluorescent tubes of the coordinate of each point, generate a kind of color, the corresponding successively redness of 1--7 point, yellow, green, cyan, blue look, magenta, white, digital quantity after 8 A/D transform is incremented to 255 from 0, and corresponding color coordinates is from 1 continuous transition to 7.
2. three phase sine alternating current model
As shown in Figure 5, use the model of three-phase current in the three phase sine alternating current or voltage, in the three phase sine alternating current, A, B, C three-phase voltage are as follows:
u
A＝U
m?sinωt
u
B＝U
m?sin(ωt-120°)
u
C＝U
m?sin(ωt-240°)＝U
m?sin(ωt+120°)
A key property of three-phase alternating current be any time the three-phase sum be 0, if each all adds mutually Um, then sum is 3Um any time.
3. positive pyrometric cone model
As shown in Figure 6, two models in association schemes one and the scheme two, it is constant to keep the three to light the time sum, and travels through all possibilities.On the gore that is made of R1, G1, B1 in Fig. 6, three's sum remains unchanged, and every bit is all represented a kind of color, therefore triangle repeatedly need only not covered once to get final product.The course of work is: 8 bit data after A/D transforms----〉tabled look-up, and (being obtained by color model) obtains R, G, B lights the time----〉light the three primary colours great power LED successively and just can show desired color.
