Abstract

The invention provides a control method for changing color of an LED neon lamp; a power supply is firstly input to an electronic control device so as to generate three sets of different output control power supplies; the output control power supplies are connected to an LED three-primary-color unit formed by three colors of red, green and blue; the LED three-primary-color unit is controlled by the output control power supplies of the device respectively based on red, green and blue colors; and by utilizing the color mixture principle of red, green and blue colors, and the tone of the LED three-primary-color unit is changed into various colors formed by red, green and blue colors. The LED neon lamp is formed as a basic structure light source by combining a plurality of LED three-primary-color units. Each LED three-primary-color unit is controlled by an independent electronic control device, so the LED neon lamp can combine the color changes generated by the LED three-primary-color units in the color changing modes of synchronization, synchronization, intersection, mixing, scanning, chasing, jumping and gradual change, so as to realize the effect of color change.

Description

The control method of LED neon light change color

One, technical field

The present invention relates to be used for the control method of LED neon light change color.

Two, background technology

LED is used for the rainbow lamp as light source in present market, though of common occurrence,, its change color aspect still seems, and color is comparatively dull, and its kind is few, and the purposes and the scope that cause LED to be used for neon light are restricted.

Three, summary of the invention

The objective of the invention is to propose a kind of control method of LED neon light change color,, cause it the ornamental and imperfect drawback of effect aesthetic property to occur to overcome existing LED neon light color change dullness.

The object of the present invention is achieved like this: the control method of LED neon light change color of the present invention is characterised in that: be input in the electronic-controlled installation by power supply in advance, produce three groups of different output control power supplys through this, be connected with the LED three primary colors unit of forming by three kinds of colors of red, green, blue again, the control power supply of being exported by this device by the red, green, blue look is controlled LED three primary colors unit respectively, utilize red, green, blue colour mixture principle, make the tone of LED three primary colors unit, become the multiple color that constitutes by red, green, blue look `; On this basis, make up with a plurality of LED three primary colors unit again, constitute the LED neon light as the basic structure light source, and each LED three primary colors unit is all under electronic-controlled installation effect independently, make the LED neon light by synchronous, asynchronous, intersect, mix, scan, chase, the color transformed pattern of jump, gradual change, the color change that is produced by a plurality of LED three primary colors unit makes up, thereby realizes the effect of colors changing hue.

Utilize the present invention can make the LED neon light produce the more change effect of horn of plenty of color, compare with common monochromatic LED neon light, have very strong ornamental and ornamental, can be widely used in advertisement screen curtain wall, performance stage and beautify the city streets, places such as building view, scenic spot.

Four, description of drawings

Fig. 1, be the principle schematic that proposes electronic-controlled installation according to the present invention;

Fig. 2, be to propose circuit diagram by the synthetic LED three primary colors unit of three kinds of color-set of red, green, blue according to the present invention;

Fig. 3, be the circuit diagram that proposes the LED neon light according to the present invention.

Five, embodiment

Below in conjunction with drawings and Examples principle of the present invention and embodiment are further described:

Mark among the figure: R,---red control end; G,---green control end; B,---blue control end; V1, V2, V3---represent a LED three primary colors unit respectively; Q,---common port.

In the drawings, the control method of LED neon light change color of the present invention is characterised in that:

1. be input in the electronic-controlled installation by power supply in advance, output through electronic-controlled installation, produce three groups of different output control power supplys, described electronic-controlled installation has four outputs, and one of them output is common port Q, three outputs in addition are independently control end, and these outputs connect the red control end R of LED three primary colors unit, green control end G and blue control end B respectively.

2. described LED three primary colors unit is made up of three kinds of colors of red, green, blue, and an end of identical polar in the LED three primary colors unit is connected together as common port Q, and its excess-three end is as control end R, G, the B of three kinds of colors of red, green, blue.

3. common port Q and redness, green, blue control end R, G, the B with described LED three primary colors unit is connected respectively on the corresponding terminals of electronic-controlled installation, variation by electronic-controlled installation output control power supply, can realize the consistency that integral color control changes, make the glow color of LED three primary colors unit can send the red, green, blue monochrome, can send again by these three kinds of multicolour that color combination forms.

4. by two LED three primary colors unit combination V1, V2 or abovely constitute the LED neon light as the basic structure light source, each LED three primary colors unit is all under electronic-controlled installation effect independently, make the LED neon light by synchronous, asynchronous, intersect, mix, scan, chase, the color transformed pattern of jump, gradual change, the color change that is produced by a plurality of LED three primary colors unit makes up, thereby realizes more abundant colors change effect.

Really, according to the present invention, the LED neon light that is made of as the basic structure light source two LED three primary colors unit combination is carried out the control of color change, and the effect of the colors changing hue that produces is but less than by three LED three primary colors unit combination V1, V2, V3 or the above LED neon light that constitutes as the basic structure light source.Certainly, in order to save production cost, can satisfy the practical application needs preferably again, the preferred plan of taking is: the LED neon light that is made of as the basic structure light source three LED three primary colors unit V1, V2, V3 combination is carried out the control of colors changing hue.

According to principle of the present invention, this control method can be applied to any LED neon light tube or LED neon lamp belt.

Described above only is preferential execution mode of the present invention.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from the principle of the invention, can also make some improvement and application, this also should be considered as belonging to protection scope of the present invention.
