Existing plastic dam just plays the effect of blocking and separating, and it has also carried out certain blocking to LED element luminous when blocking, wasted resource, thereby increased use cost.

The utility model content

For solving the problems of the technologies described above, the utility model proposes a kind of plastic dam of LED display, can under the identical situation of LED light-emitting component quantity, improve the luminescence efficiency of display screen, saved resource, reduced use cost.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of plastic dam of LED display evenly is provided with the through hole that is used to place the LED light-emitting component on it, described through hole is horn-like through hole, and through-hole wall is a white, and described through-hole wall also is provided with photocatalyst layer.

Preferably, the surface of described plastic dam also is provided with black waterproof layer and photocatalyst layer.

Preferably, the height of described LED light-emitting component and the height of described horn-like through hole equate or are lower than the height of described horn-like through hole.

Pass through technique scheme, the utility model is that the through hole on the plastic dam is set to trumpet-shaped through hole, and its inwall is set to white, can improve the LED emitting component by such being provided with, economize on resources, reduce production costs, simultaneously, on the inwall of horn-like through hole, also be provided with photocatalyst layer, can prevent the adhesion of dust, save the artificial cost that cleans.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the side view of the disclosed a kind of LED display of prior art;

Fig. 2 is the side view of the disclosed a kind of plastic dam of the utility model embodiment.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of plastic dam of LED display, and referring to synoptic diagram shown in Figure 2, the horn-like through hole 21 that it is provided with regular proper alignment is used to place the LED light-emitting component.Each LED light-emitting component comprises one or more LED light emitting diodes, for example, be provided with a red LED light emitting diode in each LED light-emitting component, an one green LED light emitting diode and a blue LED, and the distribution all triangular in shape of each LED light emitting diode, and each LED light emitting diode adopts the black silicon resin-encapsulated.

Because the color of each the LED light emitting diode combined in each LED light-emitting component, the quantity of combination are all identical with the shape of arranging, and the LED light emitting diode that each color is identical is same class, therefore, can make the whole LED display screen, when display graphics, literal, letter or animation etc., show homogeneous, display effect is good.

Horn-like through hole 21 on all corresponding plastic dam of each LED light-emitting component places in the horn-like through hole 21 each LED light-emitting component fully, and its height equates with the height of horn-like through hole 21 or less than the height of horn-like through hole 21.The effect that plastic dam has played protection and isolated each LED light-emitting component; can avoid each LED light-emitting component in transportation, installation and use, to damage because of collision; and; can play and isolate the adjacent LED light-emitting component; prevent the effect of crosstalking each other; simultaneously, also played and block circuit board and reach effect attractive in appearance.Wherein, horn-like through hole 21 on the plastic dam, its horn shape can reach the effect of expanding light, and its inwall be white, can improve the LED emitting component effectively, and then the luminescence efficiency of entire display screen is improved, the display screen of same specification under the situation that can reach same brightness, uses the plastic dam with horn-like through hole can save the usage quantity of LED light-emitting component, using electricity wisely reduces use cost.

Also be provided with photocatalyst layer 22 on the inwall of horn-like through hole 21, photocatalyst layer is the compound word of light and catalyst (catalyzer), photocatalyst be a kind of be the photosemiconductor material general name with photo-catalysis function of representative with the Nano titanium dioxide, be the current ideal material of administering indoor environmental pollution in the world.

Photocatalyst is under the irradiation of light, can produce similar photosynthetic light-catalyzed reaction, free hydroxy that generation place oxidability is extremely strong and acticarbon oxygen, has very strong photooxidation restoring function, various organic compounds of oxidable decomposition and part inorganics, can destroy the cell membrane of bacterium and solidify the protein of virus, but kill bacteria and decomposing organic pollutant, organic contaminant is resolved into the water and the carbon dioxide of inorganic pollution, thus have extremely strong sterilization, deodorizing, mildew-resistant, antifouling, self-cleaning, remove formaldehyde, air purification function.The characteristic of photocatalyst is to utilize airborne oxygen molecule and hydrone that the organism that is contacted is converted to carbon dioxide and water, and self does not change, and but can promote the material of chemical reaction, the term of validity is very permanent in theory, maintenance cost is low, and simultaneously, titania itself is nontoxic.

Also be provided with one or more layers water barrier on the surface of plastic dam, and water barrier is a black waterproof layer 23, because black has good light absorptive, can absorb and be radiated at the lip-deep light of plastic dam, the influence of eliminate the external emission light of the exiting surface of each LED light-emitting component, overflowing emission light and refract light etc. makes the light of exiting surface of each LED light-emitting component more concentrated.

And, being provided with photocatalyst layer 22 equally on the surface of black waterproof layer 23, its effect is identical with the effect of the photocatalyst layer of horn-like inwall.Because the performance characteristics of photocatalyst can reduce the dust adhesion of plastic dam, thereby save the cost of artificial cleaning, and, the effect that photocatalyst layer can also be brought into play high efficiency deodorizing sterilizing, purify air.And photocatalyst layer 23 can also be wholely set with black waterproof layer 23, simplifies production procedure, reduces production costs.

The utility model is that the through hole on the plastic dam is set to trumpet-shaped through hole, and its inwall is set to white, can improve the LED emitting component by such being provided with, economize on resources, reduce production costs, simultaneously, on the inwall of horn-like through hole, also be provided with photocatalyst layer, can prevent the adhesion of dust, save the artificial cost that cleans.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
