Description

A light bar connecting clip

technical field

The utility model relates to the technical field of display screens, in particular to a light bar type LED display screen.

Background technique

Strip-type LED display is widely used because of its strip-shaped, hollowed-out product form and light transmission, which does not affect ventilation and lighting. Therefore, how to further simplify the installation structure of strip-type LED display and reduce installation and maintenance lamps The complexity of the strip-type LED display is a problem that developers are constantly thinking about. With the simplification of the structure of the strip-type LED display, the LED light strip has appeared in the form of a single PCB board and is directly installed on the display structure.

For example, the Chinese patent number is 201420302092.4, and the patent of the utility model titled side-emitting glass display screen discloses a glass display screen, which includes a fixed frame and a plurality of PCB boards, and the plurality of PCB boards are fixed on the fixed frame in parallel intervals. Each PCB board includes multiple LED lamp beads and constant current driver chips. The anodes of the multiple LED lamp beads are connected to the power input terminal, and the cathodes are connected to the output pin of the constant current driver chip. The multiple LED lamp beads are side-emitting LED lamps. Beads, whose light-emitting surface faces the outside of the glass display screen, the utility model PCB board structure is more compact, increases the transparency of the glass display screen, makes it more beautiful, and has better decorative effects. The side-emitting glass display screen belongs to the light bar Type LED display screen, LED strips are installed on its structure to realize luminous display.

The most basic feature of the LED display is that it can be spliced infinitely and arbitrarily. However, due to the length limitation of the transmission of the signal and power on the LED light strip, the power and signal of the LED light strip are input from one end, and one or several strips are spliced by welding connectors. The LED light strip will reach the limit length of the transmission, and the connection of the display screen may continue. The continuation of the light strip will re-connect the power supply and signal. Therefore, there will inevitably be two LED light strips separated by large LED splicing screens. Empty connection, that is, there is no electrical connection, and there is no soldering of connectors. We know that PCB boards are prone to slight deformation during production and installation, which has no effect on use. However, when two LED light strips PCB boards are straight Arranged, and there is no fixed joint at the junction, there will be a certain position deviation between the ports of the two LED light strips. This small deviation will seriously affect the overall effect of the splicing screen composed of a large number of light strips.
