Abstract

The utility model relates to a two-color LED decorative lamp, comprising a plurality of LED lamps of two colors forming as a serials lamp, a control device connecting the power supply and the serials lamp. The serials lamp comprises a plurality of groups, and each group consists of two LED lamps of different color with the positive-negative poles back-to-back connected. The control device controls the change of the current direction. Changing the direction of the same serials lamp by the control device, the light-emitting color of the serials lamp can be changed, without adding more serials lamps, having a simpler connecting wire structure. Two LED lamps of different color are equipped in the same lamp group, and the whole LED decorative lamp has a smaller bulk, thereby being convenient to be suspended or enlaced to the adornment or space engaged.

Description

A kind of dual-colored LED ornament lamp

Technical field

The utility model relates to a kind of decorative lamp, more particularly, relates to a kind of dual-colored LED ornament lamp of convertible two kinds of colors.

Background technology

The LED ornament lamp of polychrome conversion as required goes out multiple color, sends motley radiance, and the environment around giving brings decorative effect.As shown in Figure 1, 2, the LED ornament lamp of existing double-colored conversion is generally connected with controller after the lamp connection in series-parallel by two kinds of colors again, conducting sequential by controller control different colours lamp string place branch road, make that the lamp string of different colours is luminous in the different periods, thereby the whole LED ornament lamp produces the effect of colour switching.Owing to be provided with two branch roads, make the line complexity of whole LED ornament lamp.A LED lamp on the different colours lamp string is combined and is formed a lamp group simultaneously, is provided with certain distance as required between the different lamp groups, makes that the overall volume of this LED ornament lamp is bigger than normal, uses inconvenience.

The utility model content

The technical problems to be solved in the utility model is that the deficiency at dual-colored LED ornament lamp connecting line construction complexity in the prior art provides the dual-colored LED that a kind of connecting line construction is simpler, volume is littler ornament lamp.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of dual-colored LED ornament lamp, comprise the lamp string of forming by a plurality of LED lamps of two kinds of colors and be connected power supply and described lamp string between controller, described lamp string comprises a plurality of lamp groups of being made up of two color differences and the cross-coupled LED lamp of both positive and negative polarity, described a plurality of lamp group is connected in series, and each the LED lamp in each described lamp group is connected with LED modules with different colors lamp homopolarity in next lamp group; Described controller is controlled the variation of the sense of current on the described lamp string.

In dual-colored LED ornament lamp described in the utility model, two LED lamps in described lamp group are arranged in the lamp body.

In dual-colored LED ornament lamp described in the utility model, described controller is connected with power supply by plug.

Implement dual-colored LED ornament lamp of the present utility model, has following beneficial effect: be in series by a plurality of lamp groups by described lamp string is set, include cross-coupled two the LED lamps of color difference and both positive and negative polarity in each lamp group, a plurality of lamp groups guarantee when being connected into the lamp string that the LED lamp of color of the same race connects in the same way, as long as change the sense of current on the same lamp string by controller, just can be so that this lamp string send the light of different colours, and a plurality of lamp strings need not be set again, its connecting line construction is simpler.Two different LED lamps of color in the same lamp group are arranged in the same lamp body, make that the volume of whole LED ornament lamp is littler, can hang easily or be wrapped in during use on the article or place that need to decorate.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the circuit theory diagrams of dual-colored LED ornament lamp in the prior art;

Fig. 2 is the structural representation of dual-colored LED ornament lamp in the prior art;

Fig. 3 is the circuit theory diagrams of the utility model dual-colored LED ornament lamp;

Fig. 4 is the structural representation of the utility model dual-colored LED ornament lamp.

The specific embodiment

As shown in Figure 3, in the preferred embodiment of dual-colored LED ornament lamp of the present utility model, comprise lamp string 20 that a plurality of LED lamps 10 form, be connected the controller 30 between power supply and the described lamp string.The LED lamp has two kinds of different colors, as red and green, yellow and blueness etc.The LED lamp 10 of two different colours is formed a lamp group 30.In a lamp group 30, the positive pole of first kind of color LED lamp links to each other with the negative pole of second kind of color LED lamp, and the negative pole of first kind of color LED lamp links to each other with the positive pole of second kind of color LED lamp, and in the promptly same lamp group 30, two LED lamps of different colours form the both positive and negative polarity interconnection.A plurality of described lamp groups 30 are cascaded and form described lamp string 20.In described lamp string 20, the negative pole of first kind of color LED lamp links to each other with the positive pole of first kind of color LED lamp in next lamp group in each lamp group 30, and the positive pole of second kind of color LED lamp links to each other with the negative pole of second kind of color LED in next lamp group, be that being connected in series between each lamp group and next the lamp group a little is arranged in the same lamp group cross-connection point between two kinds of color LED lamps, form in each lamp group in first in the color LED lamp and next lamp group the lamp string 20 that color LED lamp homopolarity is connected in second.This lamp string 20 is connected to external power source by a plug 40, is provided with described controller 50 between plug 40 and lamp string 20, and this controller 50 can be controlled the variation of the sense of current in the lamp string 20.When electric current is first kind of direction, first kind of color LED lamp forward conduction in the described lamp string 20, and the oppositely not conducting of second kind of color LED lamp makes described lamp string 20 send the light of first kind of color; When the controller 50 control senses of current are changed in second direction, oppositely not conducting of first kind of color LED lamp in the described lamp string 20, and second kind of color LED lamp forward conduction, make described lamp string 20 send the light of second kind of color, thereby change the sense of current by controller 50, make same lamp string 20 just can send the light of two kinds of different colours, and do not need a plurality of lamp strings, its connecting line construction is simpler.

As shown in Figure 4, in the preferred embodiment of above-mentioned the utility model dual-colored LED ornament lamp, two LED lamps in the described same lamp group can be arranged in the same lamp body 60, its both positive and negative polarity interconnection each other is arranged on lamp body 60 inside, make this lamp group be arranged in the lamp body 60, and the lead-in wire of this lamp body 60 only has two, makes that the volume of whole ornament lamp is littler, weight is lighter.During use, can hang easily or be wrapped on the article of need decorating or place, and not need special load-bearing or fixed support such as nail to fix this ornament lamp, use more convenient, flexible.
