Description

An outdoor strip-shaped high-resolution LED fully waterproof module

technical field

The utility model relates to an LED display screen module, in particular to an outdoor strip-shaped high-resolution LED full waterproof module with high resolution and extremely light weight.

Background technique

In modern society, LED displays can be seen all the time, ranging from large LED curtain walls in shopping malls to small shop signs, all of which use LED displays. The LED displays are spliced into a complete box by multiple LED display modules. body display unit, and then the box display units are spliced one by one and fixed on the steel frame structure outside the building. The installation of conventional display screens requires drilling holes on the outer wall of the building, driving in steel nails, installing keels, and turning the LED display The screen module is fixed on the keel in sequence, and the power line and signal line of the LED display module are connected at the same time, that is, the installation of one LED display is completed.

The outdoor display must have IP66 or above waterproof capability. Conventional display modules are all "solid board" methods. Due to their structural reasons, they must be matched with sheet metal cabinets or die-cast cabinets to achieve waterproof effects, and only the first half of the cabinet can reach outdoors. Requirement level, the second half still relies on the construction of steel structure to seal its lack of waterproofing, so often the display screen of a display screen project should be about 65KG/square, and in order to meet the load and wind and earthquake resistance of this display screen, etc. For the influence of other external factors on the display screen, the steel structure that needs to be made must have a relatively high strength, so the steel structure must also be about 60KG/square. Such a display project will reach about 125KG/square, which will add a lot of additional load to the building. High requirements are placed on the application environment,

In this environment, a high-resolution LED strip-shaped outdoor fully waterproof module came into being. This design got rid of the original box model and directly integrated and waterproofed the display module. It can be directly spliced into Outdoor LED display, which saves the weight of the sheet metal box, and the weight of the screen itself has been greatly reduced, and the components of the module are all made by opening molds, with high precision. , high standardization, and simple installation, so the strength requirements for steel structures will be greatly reduced.
