Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

In preferred embodiment of the present utility model, as shown in Figure 2, EL Cold light source 2 comprises coaxial conductor cores 21, luminescent layer 23, transparent insulating layer 24 and protective clear layer 26 from inside to outside successively; Wherein be wound with many leads 22 on the luminescent layer 23, lead 22 connects power cathode, and the conductor cores 21 that is positioned at EL Cold light source 2 centers connects positive source.In addition, be provided with the color emission layer 25 of multiple color between transparent insulating layer 24 and the protective clear layer 26.Luminescent layer 23 in the EL Cold light source 2 is the luminescenjt powder coating on conductor cores 21 surfaces, can select dissimilar luminescent materials as required, with different-thickness conductor cores 21 be carried out coated with forming above-mentioned luminescent layer 23.

As shown in Figure 3, when conductor cores 21 access positive sources, when lead 22 connects power cathode, the alternating electric field excitation that power supply produces is positioned at anodal conductor cores 21 and cathode conductor 22 interbedded luminescent layers 23, makes the atom generation transition of luminescenjt powder in the luminescent layer 23, thereby emits beam.Similarly, when containing different activator, can send the light of different colours.Again because the EL Cold light source does not have the requirement height of cold light film to luminescenjt powder to the requirement of luminescenjt powder material, be applicable to that therefore the kind of luminescenjt powder material of EL Cold light source is more, can prepare the EL Cold light source of more colors.And the color category of cold light film is single relatively, if go for more color, needs the insulating barrier of other color to assist.And can send the light of multiple color according to the EL Cold light source self of the utility model embodiment, therefore the insulating barrier that both can be provided for mixing colours can not be provided with yet.If, when between transparent insulating layer 24 and protective clear layer 26, setting up color emission layer 25,, can select the color emission layer 25 of respective color at the EL Cold light source of required color in order to enrich color category.Color emission layer 25 is not an insulating barrier transparent but that have certain color, so color emission layer 25 can play the insulation protection effect on the one hand; On the other hand, can obtain another color after the color of color emission layer 25 and luminescent layer 23 are in harmonious proportion mutually, in not changing luminescent layer 23, enrich the color of EL Cold light source thus on the basis of luminescenjt powder material.Be positioned at outermost protective clear layer 26 and only play a protective role, selecting transparent is in order not cover the light that is sent.

Because the EL Cold light source is a linear structure, is easy to mould in multiple occasion as required multiple moulding.Comprise coaxial fexible conductor core 21, the luminescent layer 23, flexible and transparent insulating barrier 24 and the flexible and transparent protective layer 26 that apply from inside to outside successively and work as the EL Cold light source; all right crooked EL Cold light source, thus mould a greater variety of shapes according to applicable situation.

From as can be seen above, at first low than special-purpose electric conducting material price because the conductor cores in the EL Cold light source is common plain conductor, be easy to buying; Simultaneously because of different with the production technology of cold light film, the composition difference of luminescent powder, required luminous composition is less, therefore prescription simply, so production cost is low.Secondly, because the EL Cold light source is a linear structure, is easy to moulding, the noctilucence that is used for various patterns, font and building profile etc. is decorated, having remedied former cold light film can't do contour structures circular and to the inconvenience that moulding brings, make the purposes of Cold light source more extensive.In addition, the principle of luminosity of EL Cold light source is that therefore emission is the high efficiency ultraviolet cold light that do not contain by excitation atomic transition emission light.

Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection range of the utility model claims.
