Abstract
The utility model discloses a multifunctional stepless color-changing color lamp of which the entire control circuit comprises a power supply, a zero-cross sampling part, an impulse-width modulation part, an oscillation part, a modulated voltage, an inverted-phase modulated voltage, a metronome, a time sequence logical part and a combinational logic circuit, etc. A combined lamp or a string of lamp chains with various colors of light, same speed rate and twelve kinds of continuous, circular and stepless gradual changes can be realized by controlling the brightness of lamps with three fundamental colors of red, green and blue and two groups of outputs with mutual inverted-phases. The speed rate of the color-changing of the color lamp is no need to be modulated and the color can dance circularly or can be selected with a fixed color. The color lamp can be used in families, public places of entertainment, color-changing fountains, borderlines of large buildings and other color decorative lamps, etc.
Description
The utility model relates to the combination lamp that a kind of tool is ornamental and effect is changeable, particularly a kind of multifunctional stepless color-changing festoon lamp by analog-and digital-circuit control.
So far, existing broken colour light fixture can only send certain fixing coloured light.The variable color though machinery CD variable color lamp can circulate, volume is big, and noise is also big, and the speed that changes is not easy to regulate, and more is not easy to constitute changeable look Assembled lamp; Electronically controlled Color-changing lamp device, as the special-purpose thick film circuit of the RS63 of U.S.'s product, and Chinese patent " electronics automatic color-changing, select arbitrarily look illusion the color lamp " (patent No.: 89201567.5) etc., though can circulate gradual change coloured light, the fixation that have, but generally do not possess the function of step-less adjustment variable color speed, and all only be one group of output.
The purpose of this utility model just provides a kind of color-changing festoon lamp that coloured light is changeable, function is a lot of by analog-and digital-circuit control.It can not only circulate automatically stepless gradual change or various colour of saltus step, speed that can step-less adjustment variable color speed; And can select certain photochromicly it to be fixed up no longer change; And the control output of two groups of reciprocal phases can be arranged, many circulation variable colors, variation is different, rate of change is identical combination lamp or the lamp string of becoming capable of being combined.
The purpose of this utility model is achieved in that
Red, green, blue three the primary colours bulbs of the control circuit control that constitutes by analog-and digital-circuit, make its in twos between the different proportion of brightness be projeced on milky white or the frosted lampshade, also or project on white or the light plane.By the spacing color mixed principle of three primary colours, can synthesize various coloured light.If red green blue three bulbs are made up three control of control circuit output line respectively, can obtain 6 kinds of combinations; Add 6 kinds of combinations of one group of anti-phase output, it is different then can to obtain 12 kinds of variations, and the identical combination lamp of rate of change.If make the stepless gradual change of red green blue three color lamp, then can obtain stepless gradual change photochromic effect; If make its brightness jump variation in twos, then can obtain color saltus step effect; If make certain color at a time stop to change, then can make this color fix and keep the coloured light of this moment.But its variable color speed step-less adjustment.

3Nei Lanse start from scratch rise to the brightest, this moment be purple, by that analogy.From T
1To T
6Be one-period, synthetic respectively green, yellow, red, purple, blue, green grass or young crops and Neutral colour thereof are the cycle with six beats promptly later on, the circulation variable color.R ', g ', b ' brightness curve are just in time anti-phase with r, g, b curve, if also corresponding red, green respectively, blue three kinds of looks bubble, then from T
1To T
6Synthetic respectively purple, blue, blue or green, green, yellow, red and Neutral colour.If from r, g, b and r ', g ', b ', get three combinations arbitrarily, can obtain 20 kinds; Every kind of combination can get corresponding red, green, blue three primary colours bulb transposing again, thereby obtains six kinds of arrangements, changes different combining form so always have 120 kinds.Now get wherein and be combined as basic combination for two kinds, can keep uninterrupted continuously stepless gradual change look of circulation of light or saltus step look with r, g, b and r ', g ', b '.
The operation implementation procedure is described below.
As shown in accompanying drawing 1, with red, green, blue tri coloured lantern by red green orchid, green, the green red orchid of red orchid, green orchid is red, Lan Hong is green, blue green red six kinds of arrangements connect r, g, b and r ', g ', b ' line respectively, it is covered in milky white or the frosted lampshade, so just constituted 12 kinds of Assembled lamps.Connect with the mains, each lamp is with six kinds of Essential colour: blue purple of reddish yellow malachite and Neutral colour thereof begin the variable color that circulates.As shown in accompanying drawing 2, if r, g, b line connect respectively red, green, blue three looks bubble, then lampshade is with blue green grass or young crops of greenish-yellow purple and Neutral colour thereof the stepless gradual change look that circulates; If connecing red, blue, green three looks, r, g, the three-way correspondence respectively of b steep, then with purplish red yellowish green green grass or young crops of orchid and Neutral colour thereof the stepless gradual change look that circulates; Connect red, green, blue three looks bubble respectively if r ', g ', b ' are three-way again, then with the purple blue dark green yellow red and Neutral colour stepless gradual change look that circulates.So analogize, promptly become the Assembled lamp of the different and rate of change same loop variable color of 12 kinds of variable colors.Also can to ask for wherein some small cups and be combined into 1～12 combination according to actual.When with K switch
1When opening, the color when each lamp stays open, i.e. fixation; To continue the circulation variable color when closing.Regulator potentiometer W can step-less adjustment variable color speed speed.K switch
2Beat when the A point each lamp stepless gradual change look that circulates; K
2Beat when the B point, then become circulation jump variable color.
The utility model has the advantage of, can stepless gradual change and jump circulation variable color, therefore speed that again can step-less adjustment variable color speed goes for the needs of various occasions. In the ardent occasion of festive air, the joint that can accelerate rightly gradient color speed or jump variable color gathers; In quiet and tastefully laid out quiet place, can slow down variable color speed, the variable color process is finished unconsciously. Can also be combined into 12 kinds of circulation gradual changes or jump to change, variable color is different and speed is identical combination lamp, and can select arbitrarily look. Can be used for family, public place of entertainment, can also be as variable color fountain and large-scale building constructions outline line lamp, and do not have Radio frequency interference. Be to integrate ornamental, practicality, color is pure, and speed is adjustable, makes up changeable a kind of multifunction electronic control variable color lamp.
