LED two-sided overturning advertisement board structure

Abstract

The invention relates to an LED two-sided overturning advertisement board structure which comprises a triangular prism two-sided aluminum profile and a PCB (Printed Circuit Board) arranged on one side face of the two-sided aluminum profile from bottom to top, wherein a plurality of LED lamps are uniformly arranged on the PCB, and a plurality of independent lamp holders for covering respective LED lamps are mutually independently arranged on the PCB; and extension edges are extended from another two intersecting side faces of the two-sided aluminum profile along the opening direction of an included angle, and a sealing layer is filled in a space surrounded by the extension edges, the PCB and the independent lamp holders. In the invention, the independent lamp holders are adopted and the sealing layer is filled in the whole surface, so that uneven illumination is prevented, the problem that the LED advertisement board is soaked by rainwater in outdoor use is effectively eliminated, the quality reliability and the service life of the advertisement board are increased, and the maintenance frequency is reduced. Meanwhile, the filling amount can be accurately controlled, efficient and automatic production is realized, the processing cost is greatly lowered, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a billboard structure, in particular to an outdoor double-sided LED billboard structure. Background technique [0002] Currently commonly used outdoor double-sided billboards, in order to prevent rainwater leakage and PCB leakage from causing damage to the circuit, generally fill the sealing material between the integral lamp holder and the PCB board intermittently. The integral lamp holder is often due to its large area. , during injection molding, it is prone to shrinkage and deformation, resulting in uneven light concentration of the lamp head and affecting the lighting effect.

[0002] Currently commonly used outdoor double-sided billboards, in order to prevent rainwater leakage and PCB leakage from causing damage to the circuit, generally fill the sealing material between the integral lamp holder and the PCB board intermittently. The integral lamp holder is often due to its large area. , during injection molding, it is prone to shrinkage and deformation, resulting in uneven light concentration of the lamp head and affecting the lighting effect. At the same time, a non-reusable disposable insulating spacer is set between the PCB board and the aluminum profile. In the middle, it is easy to wander in the gap between the PCB board and the lamp holder, which affects the quality. Because there are multiple intermittent sealing parts, when leakage occurs, the investigation of the leakage point is very troublesome and inefficient. Production During the process, the filling method is often adopted side by side and sealing point by point. After filling the sealing points on one side one by one, it is necessary to wait for the sealing material to solidify before turning over and continuing to fill the sealing points on the other side. It is impossible to realize automatic production, which is not only inefficient , and the quality is difficult to control
