Embodiment 1

[0035] Embodiment 1: A kind of active light-emitting film, see figure 1 , the thin film is a layered structure, from left to right are substrate 1, LED light-emitting chip 2, phosphor glue 3, scattering layer 4, and retroreflective layer 5. The substrate 1 is a flexible PCB, which can be made of glass fiber, aluminum base, copper base, ceramic base, polyester fiber, polyimide or indium tin oxide, and polyimide is used in this embodiment. Weld LED light-emitting chips 2 on the upper surface of the substrate 1, see figure 2 , LED light-emitting chips 2 are soldered at equal intervals of 2mm×2mm, and the LED light-emitting chips 2 are one of COB LED, SMD LED, CSP LED, Mini LED, Micro LED, QLED, OLED, and Mini LED is used in this embodiment. When white light needs to be emitted, white LEDs or RGB LED chips can be used directly, or phosphor layers or quantum dot film layers can be coated on blue LED chips. Above the LED light-emitting chip 2 is a scattering layer 4, the material...

Embodiment 2

[0044] Embodiment 2: A kind of active luminous signboard, see image 3 and Figure 4 , including a rectangular bracket, the bracket is provided with a slideway 101 around it, the signboard panel 100 slides into the bracket from the bottom of the slideway 101, and then fixed by the rivet 103 on the back of the bracket. A bottom film 102 is pasted on the front of the signboard panel 100, and an active luminescent film is pasted on the bottom film to form a light emitting part. The power supply and control device are fixed with screws on the back side of the signboard panel 100 . A concealed wire hole is opened on the signboard panel 100, and the active luminescent film is connected to the above-mentioned power supply and control device through the wire hole.

[0045] The manufacturing steps of the above-mentioned active luminescent sign are as follows:

[0046] S1: Use aluminum to make the bracket and sign board panel, and there is a slideway on the bracket, install the alumi...

Abstract

The invention discloses an active light-emitting film, an active light-emitting signboard and a preparation method thereof, and aims to solve the technical problems that an existing active light-emitting signboard is complex in structure and difficult to manufacture, and resources cannot be reasonably utilized. The active light-emitting film comprises a substrate, an LED array, a scattering layer,fluorescent powder glue and a retro-reflection layer, the LED array is arranged on the substrate, the scattering layer is fixed above the LED array, the space between the substrate and the scatteringlayer is filled with the fluorescent powder glue, and the retro-reflection layer is arranged on the side face, back on to the LED array, of the scattering layer; and the active light-emitting sign comprises a support, a signboard panel, a bottom film and an active light-emitting film, the signboard panel is fixedly connected with the support, the bottom film is adhered to the front surface of thesignboard panel, and the active light-emitting film is adhered to the bottom film. The active light-emitting film is directly pasted on an existing signboard, the size is reduced, manufacturing is convenient, and brightness is uniform.

Description

technical field [0001] The invention relates to the technical field of luminescent signs, in particular to an active luminescent film, an active luminescent sign and a preparation method thereof. Background technique [0002] Most of the current luminous signs are box-type structures, using patch-type LED light sources inside, and projecting light onto the back of the retroreflective film by direct rear projection or side light guide to light up luminous characters or patterns. The patent document with the publication number CN110306457A and titled "A Light Source Splicing and Combination Active Luminous Traffic Sign" discloses an active luminous sign, which aims to solve the problem of difficult maintenance and replacement of the light source board. [0003] However, the above-mentioned box-type luminous signs are relatively large in size, complex in assembly process, and increased in weight, so there are still great difficulties in production; When the network number chan...
