Detailed Description

The utility model is further elucidated with reference to the drawings and the embodiments.

As shown in fig. 3, the present invention provides a side-lighting digital display module, which comprises a PCB 5 and a plurality of light-emitting wicks 4 disposed on the PCB 5, wherein the PCB 5 is disposed on a connecting frame 8, a panel 1 is disposed on the top end of the connecting frame 8, the bottom end of the connecting frame is mounted on a translucent light-guiding base 7, a connecting surface of the panel 1 and the connecting frame 8 is respectively provided with a fixture block 11 and a clamping groove 81 which are matched with each other, the panel 1 is fixed on the connecting frame 8 by the fixture block 11 in the clamping groove 81, the periphery of the translucent light-guiding base 7 extends upwards to form a light-guiding portion 71, the light-guiding portion 71 surrounds the PCB 5, the light-guiding portion 71 is connected to the panel 1 by a bracket 3, in this embodiment, the upper and lower surfaces of the bracket 3 are respectively bonded and fixed to the panel 1 and the light-guiding portion 71 by 3M back glue 2, the inner side of the bracket 3 abuts against the connecting frame 8, the light-emitting wicks 4 are side-emitting and are disposed near the light-guiding portion 71, in this embodiment, the light emitting lamp core 4 is an LED lamp bead with side light emitting, the LED lamp emits light towards the light guiding portion 71, the high-brightness electroplating base 6 with an arc-shaped structure is arranged at the light guiding portion 71, and a light emitting opening 10 is formed between the high-brightness electroplating base 6 and the panel 1.
