People have a lot of doubts that the LED spotlights can be used when water enters.
With the development of economy, people have improved the quality of life and prefer a relaxing light. Users like the variety of effects of LED linear lights, which will decorate the night city brightly and colorfully. It is very important for urban lighting projects.
The dark night blooms with colorful effects, and the extensive use of led line lights can be seen everywhere in the decoration and use of overpasses, guardrails, building outlines, and entertainment squares. Not only the beautification of the night view of the city, but also the contribution to the development of environmental protection and energy conservation.
Spotlight manufacturers' LED linear lights are mainly composed of led lamp beads, circuit boards, electronic components, wires, shells, waterproof silicone, lenses, glass, etc. Use anti-ultraviolet and anti-aging silica gel for pouring circuit boards. This adhesive has good adhesion, is not easy to crack, and is not easy to age. It protects the lamp beads and electronic components from short-circuit burnout in rainwater, and the protection level is above IP65.
The water intake process is divided into: temperature change, air pressure generation, squeeze the outer tube, seal failure, and negative air pressure to absorb water. In addition to temperature changes, the temperature influences include solar radiation heating, greenhouse effect heating, and heating of the circuit in the tube. When the guardrail tube is sealed and waterproof enough, the tube does not leak, and the cracked tube will increase.
After the LED linear lamp is installed, it will be affected by temperature changes. The air pressure in the tube will continuously change with the temperature. The tube shell will expand at high temperature, and the tube shell will be squeezed at low temperature. The sealant of the wire inlet and end cap will be physically affected. Deformation, small cracks will appear after a long time. When the temperature rises, the air will leak. When the temperature is lowered, the air will be inhaled. Then the water attached to the outside of the tube will slowly enter the tube.
