Although the scheme can realize control of various color changes, the usage amount of the LED display screen module is increased, the cost performance is low, and the market popularization is difficult.

The invention content is as follows:

the to-be-solved technical problem of the utility model is to provide an advertising light boxes discolours, and this lamp house uses a small amount of LED display screen module can realize the many colours of big word of luminous and change.

In order to solve the technical problem, the color-changing advertising lamp box comprises a frame, at least one LED display screen module, a hanging frame and a front face mask; the LED display screen module is fixed on the inner side of the frame; a plurality of hanging racks are distributed at the rear edge of the frame; the front cover is fixedly covered on the front of the frame, and the front surface of the front cover is sprayed with the advertisement information part.

The frame can be circular or oval.

The frame can also adopt an N-edge shape, and the N LED display screen modules are respectively fixed on the inner sides of the N edges of the frame.

N≥3。

Furthermore, the utility model also comprises N reinforcing rods; n stiffeners are arranged in the frame, and two ends of each stiffener are respectively connected with two adjacent edges of the frame.

And a hanging rack is fixed at the N top angles of the frame.

The front cover adopts a PMMA transparent face mask or canvas.

The part of the canvas avoiding the advertisement information part is a non-light-transmitting part; the inner side surface of the light-tight part is sprayed with light-tight material or pasted with light-tight paster.

The advertisement information is character information, and a plurality of light-transmitting points are reserved in each stroke part of the character information.

Furthermore, the utility model also comprises a rear face mask; the rear cover adopts a waterproof canvas with reflection performance.

The utility model abandons the defect of single color light source, gives full play to the advantage of changing the color of the LED display screen module, and does not generate the defect of cost rise caused by excessive use of the LED display screen module; the metal frame mode can reduce the whole weight of the advertising lamp box, reduce the cost and avoid causing excessive load on the installation wall.

Description of the drawings:

the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic view of a frame structure of a color-changing advertising light box.

Fig. 2 is a perspective view of the color-changing advertising lamp box.

FIG. 3 is a diagram of a canvas with a text portion of "Wide" words.

FIG. 4 is a diagram of a canvas with a text portion of "tell" words.

In the figure: 1. a frame; 2, LED display screen module; 3. a reinforcing bar; 4. a hanger; 5. a front face mask; 51. text information; 511. a light transmission point; 52. a light opaque portion; 6. a rear face mask.

The specific implementation mode is as follows:

the following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in figure 1, the utility model discloses a color-changing advertising lamp box includes frame 1, LED display screen module 2, stiffener 3, stores pylon 4, front face guard 5, back face guard 6. The frame 1 is hexagonal, and the 6 LED display screen modules 2 are respectively fixed on the inner sides of six sides of the frame 1 to form a side light-emitting mode; the six reinforcing rods 3 are arranged in the frame, and two ends of each reinforcing rod 3 are respectively connected with two adjacent edges of the frame 1; six top corners of the frame 1 are fixed with hangers 4 for mounting and fixing the whole advertising lamp box on the surface of a wall body; the front face cover 5 and the rear face cover 6 are respectively fixed and covered on the front and the rear of the frame 1; the front surface of the front cover 5 is color-sprayed with a portion 51.

The frame 1 may also be circular, oval, polygonal or other shapes. The number of sides of the polygon is not strictly limited.

The number of the LED display screen modules 2 is not limited to 6, and the number of the LED display screen modules 2 can be flexibly set according to the shape and brightness of the frame 1.

The utility model discloses in can not set up stiffener 3 or set up the quantity of stiffener 3 in a flexible way according to intensity needs.

The front cover 5 adopts a PMMA transparent face mask or canvas. The front cover comprises an advertisement information part 51 and a light-proof part 52 of the front surface color spray; taking the canvas in fig. 3 and 4 as an example, the advertisement information is character information, a light-transmitting point 511 with any shape is reserved on each stroke part of the character information, and the inner side surface of the light-proof part 52 of the front cover 5, which avoids the advertisement information part 51, is sprayed with a light-proof material or pasted with a light-proof sticker.

The rear cover 6 is preferably a waterproof canvas with reflection performance, and the light emitting effect can be enhanced. The back of the advertising lamp box is provided with the back cover 6 in the form of waterproof canvas, and the metal bottom plate is abandoned, so that the weight of the advertising lamp box can be further reduced.

When the advertising lamp box is installed on the surface of an outdoor building, the LED display screen module in the daytime can see the color-sprayed character information on the surface of the front cover of the lamp box without being electrified, so that the energy is saved and the consumption is reduced; and the LED display screen module at night is electrified and displays various colors, and light with different colors can be transmitted out through the light-transmitting points reserved in the stroke part of the front cover of the lamp box. Because the number of the light transmission points is large and uniform, and the light transmission points are orderly arranged according to the stroke parts, the luminous large character effect with different colors can be presented.
