Abstract
The utility model discloses an indoor light shield for an LED display screen. The light shield has a base plate; light penetration holes that are matched with an LED light emitting cavity on the LED display screen in size and position are formed on the base plate; and a light proof cap is arranged on the upper edge of each row of light penetration holes. The installation of the light proof cap results in a decrease in environmental light traveling inside the LED light emitting cavity, so that light reflected by the LED light emitting cavity is softer while light emitted by the LED light emitting cavity is stronger, and information displayed on the display screen becomes clearer. The simple technical proposal adopted by the utility model solves the problem that images displayed by the LED display screen are blurred as a result of relatively strong environmental light. Furthermore, the utility model has the characteristics of simple structure and reasonable design.
Description
Technical field
The utility model relates to the parts that a kind of LED display is used, and specifically relates to a kind of indoor LED display light shield.
Background technology
Referring to Fig. 5, LED display 4 is that the luminous chamber of several LED 5 horizontal vertical array are become array, by external control Driver Circuit, makes that wherein the luminous chamber of some LED is luminous in the specific time sequence section, shows required literal, pattern etc.In the prior art, indoor LED display all adopts the modular structure form of moulding shell can LED, the surface of display screen is not provided with light shield, in the strong places of light such as environment for use daylighting abundance or semi-outdoors, the light that enters luminous chamber is just more, and its reflected light also can be correspondingly stronger, and the light that LED sends will be submerged in these reflected light, cause the shown literal of LED display, pattern etc. to be desalinated, so that differentiate unclear.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical matters, and a kind of indoor LED display light shield is provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of indoor LED display light shield, comprise substrate, be provided with on the described substrate with LED display on the light hole that is complementary of LED luminous chamber size and position, at the upper limb of every row's light hole sun-shading cap is set all.After the assembling, surround lighting will less enter the luminous chamber of LED, so its reflected light also just a little less than, it is strong that the light that LED sends just shows relatively, the displaying contents of display screen is just comparatively clear.
As preferably, described sun-shading cap laterally whole piece links to each other, and also can be segmented into the shared sun-shading cap in the luminous chamber of one or more LED.
As preferably, described substrate surface indentation, diffuse environment light better helps improving the consistance of LED display, reduces because of the inhomogeneous formed mosaic phenomenon of LED light shield outside surface reflected light.
The utility model can use black plastic or elastomeric material to make, and the height of sun-shading cap can be done suitable adjustment according to the environment for use of LED display, brushes glue at the light shield back side during use and sticks on the led module just passable.The utility model adopts simple technical scheme to solve LED display fuzzy problem of demonstration under the strong situation of surround lighting, has characteristics such as simple in structure, reasonable in design.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: referring to Fig. 1, Fig. 2 and Fig. 5, the utility model be provided with on the substrate 1 with LED display module 4 on the light hole 2 that is complementary of LED luminous chamber 5 sizes and position, at the upper limb of every row's light hole the continuous sun-shading cap 3 of horizontal whole piece is set all.After the assembling, surround lighting will less enter the luminous chamber of LED, so its reflected light also just a little less than, it is strong that the light that LED sends shows relatively, the displaying contents of display screen is comparatively clear.
Embodiment 2: referring to Fig. 3, Fig. 4 and Fig. 5, the utility model be provided with on the substrate 1 with LED display module 4 on the light hole 2 that is complementary of LED luminous chamber 5 sizes and position, upper limb at every row's light hole all is provided with sun-shading cap 3, the sun-shading cap segmentation is provided with, and substrate 1 surperficial indentation, diffuse environment light so better helps improving the consistance of LED display, reduces because of the inhomogeneous formed mosaic phenomenon of LED light shield outside surface reflected light.All the other reference examples 1.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. an indoor LED display light shield comprises substrate, it is characterized in that be provided with on the described substrate with LED display on the light hole that is complementary of LED luminous chamber size and position, at the upper limb of every row's light hole sun-shading cap is set all.
2. indoor LED display light shield according to claim 1, laterally whole piece is continuous to it is characterized in that described sun-shading cap, also can be segmented into the shared sun-shading cap in the luminous chamber of one or more LED.
3. indoor LED display light shield according to claim 1 is characterized in that at described substrate surface indentation.
