Abstract

Provided is a chip-type LED display face mask that realizes polygonal reflection of light and can enhance the display effect of an LED display.

Can be used for outdoor LED display face masks. [Selection] Figure 2

Description

  The present invention relates to a structure of a festival mask improved to enhance the display effect of an LED display.

  The LED display is a display system in which development is performed by controlling the semiconductor light emitting diodes by assembling the light emitting diodes. The drive system is a low voltage type, and the existing LED display configurations are: light emitting diode, PCB, control board, power supply, bottom cover, face mask, cabinet, cable and so on. In general, there are two types of LED lamps, generally a shell type that packages three primary colors separately, and an SMD type that packages all colors in the same lamp. The face mask has a role of fixing and protecting the light emitting diode. The current technology is to protect the LED chip by installing a lens on the face mask at the same position of the LED chip and surrounding the diode. However, as shown in Fig. 1 below, lenses are not used, and all the lenses of the current technology have a flat structure. When used outdoors, sunlight is reflected in a single direction in the specified direction. The viewing effect is bad. In addition, since the lens has a protruding shape, the overall viewing angle of the display is also affected by the light reflection at the end portion.

  In order to solve the above problems, an object of the present invention is to improve the broadcasting effect of the LED display by improving the structure of the lens and by reflecting the light projected on the surface of the LED display in a polygonal manner.

  In this proposal, the technical proposals adopted to solve the technical problem are as follows.

  A kind of chip type LED display face mask is composed of the following parts: substrate, lens integrated with substrate. The described lens has a dot matrix arrangement, and the characteristic structure is that the LED lamp and LED chip positions are equal, and the lens is a protruding case surrounding the LED chip. The upper part of the face mask is circular or oval.

  As a technical improvement of the solution, the features of the chip-type LED display face mask described above are: The top sectional view of the face mask is that three eccentric arcs are smooth curves.

  As a technical improvement of the above proposal, the lens material mentioned is a light brown translucent PC.

  As a technical improvement of the above proposal, the described lenses are arranged in an equidistant dot matrix.

  In this new model, the original flat lens has been changed by improving the shape of the lens, the reflection angle of sunlight has been reduced, and the viewing side has improved the appreciation of the display. The cross section of the lens has a smooth arc shape, and multi-directional light reflection is realized, improving the appreciation of the display and widening the viewing angle of the display.

  This utility model can be applied to outdoor chip type LED display face mask.

An image is attached in order to explain in detail the implementation technical plan of this utility model. However, the attached image is a part of the utility model, and is not representative of the example. Engineers in this area can acquire other design proposals and attached images with the following attached images on the premise that there is no creative labor.
Fig. 1 is a sketch of the existing lens. Fig. 2 is an overall sketch of this utility model. Fig. 3 is a partially enlarged sketch of this utility model.

  From now on, the concept of this utility model, concrete structure and its technical effect will be explained clearly and thoroughly with examples and accompanying sketches, and a sufficient understanding of the purpose, features and effects of this utility model will be sought. . However, the attached image is a partial example of this utility model, and is not representative of all the examples. Other than the examples of this utility model, engineers in this area acquired on the premise that there is no creative labor These examples all belong to the protection scope of this utility model. In addition, all the relations / linkage relationships described in the text are not limited to direct connection of components, but depending on the specific implementation situation, a more excellent connection structure can be achieved by increasing or decreasing the number of connected components. It is possible to change the assembly order on the premise that there is no difference in the technical features of this utility model.

  According to Fig. 2 and Fig. 3, the kind of chip-type LED display face mask is composed of a single substrate 1 and a lens 2 integrally molded with multiple substrates 1 on the substrate 1. Reference numeral 2 denotes a dot matrix type array in which the position of the lens 2 is equivalent to the position of the LED chip on the external chip LED display. Further, the lens 2 described above protrudes to form a case surrounding the LED chip, and the upper portion of the face mask is circular or oval. By changing the lens cross-sectional shape, the original flat shape becomes an arc shape, thereby reducing the reflection angle of sunlight and improving the appreciation of the audience.

  The above LED display face mask structure features: The top cross-sectional view of the face mask is a smooth curved shape by three eccentric arc assemblies. Since the lens 2 has a structure that surrounds the LED, there is a certain demand for the lateral dimension. In addition, in order to realize the projection effect, the height of the lens 2 has a certain dimensional limit. In order to meet the dimensional requirements at the same time, the cross-sectional view of the upper part of the lens of this utility model has a smooth curved shape by three eccentric arc assemblies. In addition, the cross-sectional structure of the LED chip satisfies a certain condition and is semicircular, and is still a long arc.

  As a technical improvement of the above proposal, the lens material mentioned is a light brown translucent PC.

  As a technical improvement of the above proposal, the described lenses are arranged in an equidistant dot matrix.

  The above description is only a preferred implementation mode of the present invention. Any technical solution that achieves the object of the present invention by basically the same means is within the protection scope of the present invention.
