For ordinary users, we are not very clear about the positive light and side light in the LED large screen application. For the difference between the two, Liancheng Fa Xiaobian will take you to understand it together!
Positive Lighting Technology
Positive emitting LED is the standard lamp bead of conventional LED display, which can guarantee a viewing angle of 160 degrees.
Side Lighting Technology
The side-emitting lamp beads are installed on the upper or lower side of the circuit board. Due to the occlusion of the circuit board, only a single-sided viewing angle can be guaranteed.
The atomizing layer and anti-UV lamp shell material can effectively prevent ultraviolet rays from directly damaging the LED chip.
The ultraviolet rays reach the LED chip directly through the transparent layer, the chip will decay rapidly, and the casing will age rapidly.
Both the positive light-emitting LED and the circuit board part are 2mm thick, and the light blocking part is only 2mm thick.
The thickness of the side-emitting LED is at least 1mm, plus the circuit board of 1.2mm, and the light-blocking part is at least 2.2mm.
Positive light-emitting anti-collision ability
Positive light uses 3D patch technology to firmly mount the LED lamp beads on the side edge of the circuit board, and the four pins of the lamp bead form a plane bond with the circuit board, which can withstand 40N destructive impact.
Side-illuminated anti-collision capability
The side-emitting LED pins and the circuit board are only bonded by solder and can only withstand 10N thrust.
