Description

Multifunctional colour-variable lamp string

Along with greatly developing of economy, the active atmosphere when each commercial unit, restaurant and decor have more and more adopted lamp decoration to strengthen night, at present, application quantity is maximum remains traditional festival lamp set.This lamp is generally monochromatic illuminator, and the both just middle bulb of carrying various constant color secretly when watching, also can not divide the difference of color slightly at a distance.Now, generally all festival lamp set is become a large-area cluster of lamps, ornamental array side by side, in the hope of reaching the effect of The sky is studded with twinkling stars, still be lampion string no matter use the monochromatic burner string this moment, the effect of macroscopic view remains the same color, lacks the variation of color, has limited its range of application.

Design of the present utility model is just for making this power consumptive province of a cluster of lamps, ornamental, and cost is low, and lamp decoration easy to use has the scope of application widely, better artistic effect.The utility model by the combination by red, green, blue tri coloured lantern bubble, and produces a new illuminator, this illuminator and controller combine and will produce multi-functional color change, select the combination of different function for use, just can change and various variable color styles, produce multicoloured artistic effect.

The basic element of character of illuminator of the present utility model--bulb, still adopt the employed bulb of festival lamp set, shown in accompanying drawing one (a), with a circular wiring board (1) red, green, blue tri coloured lantern bubble is fixed in wiring board and is in the circular hole (3) that isosceles triangle arranges.The lead-out wire of bulb is welded in respectively on the contiguous Copper Foil (4).6 insulated conductors that red, green, blue tri coloured lantern bubble and neighbouring bulb link are passed fixing hole (5) respectively and then are welded on respectively on the corresponding Copper Foil.In the lampshade (6) shown in the wiring board sub-assembly load map one (b) that welding is good.3 of bulb advances 3 and goes out 6 exhausted level leads respectively by outside fairlead (7) boot.And link with neighbouring two sub-assemblies, until being connected into required specification.This single string Assembled lamp string and control unit interface link with it with a plug special (9), and the spheroidal lampshade shown in the figure one (b) is made up of the transparent plastic housing of two semicircles, and the outer surface of housing is evenly distributed with many semicircle shape projection particulate points.Make its well printing opacity, can make the refraction of light again, make mixed light more even through each particulate point.Connect the lamp string finish shown in figure one (c) and the corresponding electrical schematic diagram of figure one (c) see figure six.The shared power line of wherein red, green, blue tri coloured lantern passes through the fairlead of each lampshade successively, joins with the tri coloured lantern bubble in lamp/subassembly of least significant end.

The utility model The controller is in order to adapt to the flexibility of large tracts of land picture group case and use.The pattern that adopts four functions to exist side by side.Its function has: one, speed order variable color; Two, random random variable color; Three, audible spectrum control variable color; Four, rainbow seven looks output.Because this four classes control is assemblied in the controller simultaneously, applicable to large tracts of land and multiple mode of composition, controller can be produced different specification series, to be suitable for different loads.When selecting large-scale bidirectional triode thyristor for use, promote the also corresponding increase of electric current, corresponding increase amplifier before controllable silicon increases the promotion electric current.

Shown in the figure two is sequencing circuit.555 time base circuits wherein, the impulse generator of composition produces square-wave pulse, and the frequency of this pulse is adjusted to reach the control of variable color time by the W among the figure.This pulse is by the output of time base circuit (3) pin, CP input (1) pin of one road to IC2 counter 1.One road to selector switch K selection as the input pulse of next stage counter 2.Counter IC2 selects two tetrad synchronous addition counters for use, in this circuit only with wherein three just much of that.3,4,5 pin of IC2 are outputs of first counting of double counters, and the relation between its input pulse and the output pulse is seen figure three, and by figure three as seen, the transfer interval of every kind of color is by the cycle decision of CP pulse.

As Q1, Q2, when high potential appears in the Q3 pin, deliver to the The Trigger of Bidirectional Triode Thyristor end by emitter-follower, make the bidirectional triode thyristor conducting.Make the 220V alternating current by load and bidirectional triode thyristor and conducting.100(indigo plant like this order is appearred), 010(is red), the 110(purple), 001(is green), 101(green grass or young crops), the 011(Huang), 111(is white), 000(is black) seven kinds of colors, eight kinds of states.

The principle of counter 2 is close with waveform schematic diagram fundamental sum counter 1, and the difference part is to be provided with K switch, changes the purpose in the input pulse cycle of counter 2 by the selection of K.Thereby the variation that makes counter 2 is slower than the variation of counter 1.Suppose that the pulse period that this moment, time base circuit produced was 1 second.The variation of the load that first counter drove is every 1 second a kind of color of conversion so, if this moment, K threw position in 1, and then counter 2 and counter 1 synchronous variable color, the load capacity when being equivalent to identical variable color increases and is twice.As if the position of K being thrown in 2, color of counter 2 variations in per 2 seconds.As if the position of K being thrown in 3, color of counter 2 variations in per 4 seconds.As if the position of K being thrown in 4, color of counter 2 variations in per 8 seconds.Adopt 2 counters in sum like this, thereby reach the purpose of speed order variable color.Brought a lot of convenience when give using, with color lamp group word, or can make position and position during the picture group case, the difference between background and the theme is clearly more demarcated.

It shown in the figure four the random random variable color control circuit of controller, IC3 and IC4 are identical with IC1 function among the figure two, all are impulse generators, the output of IC1, IC3, IC4 all is connected to integrating condenser C, make square wave through after the integration, rising edge and trailing edge are pressed index law and are changed, and square wave is become approximate triangular wave and since signal source by three independently oscillator form.Three prescription wave frequencies all can be not consistent with phase place.Remove to promote three controllable silicons respectively by them, drive three groups of loads of red, green, blue then.So arbitrary moment three silicon controlled conductings degree also is not the same.Just make the glow color of red, green, blue tri coloured lantern bubble group all be in the duty of random random variable color.Thereby many employed intermediate color have been produced.Here, because IC1 is shared with the order discoloration controller, in order to reduce interference.Added the one-level emitter follower.

Shown in the figure five is audible spectrum control metachromatic principle figure.By external audio signal after emitter follower input, be divided into three the tunnel, through three RC frequency-selective networks, the signal of selecting high, medium and low three frequency ranges removes to control bidirectional triode thyristor, thereby play the conducting degree of control red, green, blue tri coloured lantern, and make color emit Protean color and come along with music, in the place that music is arranged, can receive the effect of good sound and the photochromic brightness of mapping of a set onto another mutually.

Figure six is rainbow seven look output principle figure of controller.Seven looks are by seven socket outputs.After this seven look is connected Color lamp string simultaneously, both can constitute the rainbow pattern of red, orange, yellow, green, indigo, azure, purple, also can only use with a few look compositions.W regulates silicon controlled conducting degree among the figure, green is weakened and synthetic orange.

In sum, the utility model adopts and is combined in the transparent sphere cover by the uniform refraction point in surface by red, green, blue three look miniature bulbs, constitute a luminous sub-assembly, with this sub-assembly, be connected into color string lamp lamp string on demand, again the lamp of some ganged up plug and controller joins.By flexible Application controller and four functions of depositing, make the range of application of a color discoloring cluster of lamps, ornamental more extensive.More remarkable effect.
