Main features and benefits of silicone led strip light or neon flex strips

1.Soft and curlable: silicone led strip can be curled like wires to meet the needs of various shapes. Compared with PVC led strip and aluminum groove led strip, they are soft to the touch and easy to bend. Because of their flexibility, led strip can be installed on curved surfaces.

2.Insulation and waterproof: With good insulation and waterproof performance up to IP68.

3.Strong weather resistance: Excellent weather resistance (maintaining a normal soft state for a long time under -50℃-150℃ environment), and good anti-UV effect.

4.Easy to make shapes: Various graphics, texts and other shapes can be made, and they are widely used in buildings, bridges, roads, gardens, courtyards, floors, ceilings, furniture, cars, ponds, underwater, advertisements, signs and logos, etc. Decoration and illumination.

Life of LED silicone led strips

LED is a constant current component. The constant current effect of LED led strip from different manufacturers is different, so the life span will also be different. In addition, if the toughness of copper wire or flexible circuit board is not good, it will also affect the life of LED silicone led strip.

Types of Silicone SMD strip light

SMD led strip light Silicone are all extended on the basis of bare SMD led strip light, with a service life of 30,000 hours. Currently, there are silicone sleeve led strip, silicone sleeve glue-filled led strip, and silicone extrusion led strip. Among them, silicone extrusion led strip have many types, including hollow silicone extrusion, solid silicone extrusion, and two-color silicone extrusion.

Silicone sleeve led strip VS Silicone sleeve glue-filled led strip

1.Silicone sleeve led strip(LED strip light with silicone sleeve) are made by putting silicone sleeves on the outside of bare board SMD led strip. The light transmittance is almost the same as that of bare boards, but with the protection of silicone sleeves, it can achieve a waterproof and dustproof level of IP65 or above. However, the thickness of the sleeve is generally thin, and it is easy to be affected by external force and affect the circuit board. Moreover, when bending and curling the light strip, the PCB circuit board will move or be uneven.

2.Silicone sleeve glue-filled led strip are fully infused with silicone materials on the basis of silicone sleeve led strip. It has higher weather resistance and waterproof performance, and can maintain stable operation even in humid or underwater environments. However, due to the poor adhesion of silicone, the light strip is easy to crack and fold in half. Moreover, the glue filling process costs more labor, has a higher loss rate, and the unit price is higher than that of silicone extrusion led strip. The general length is limited to 5 meters.

3.The silicone extrusion light strip is extrusion by a machine, and the silicone sleeve glue filling process has been upgraded. It not only saves labor, but also can be made into high-voltage led strip, with a longer length of more than 50 meters, and a more advantageous price, but it has high requirements on the factory's process level. If the process does not meet the standards, the defective rate of the finished product will be high, and there will be more wasted materials, which is a great test of the factory's technical strength. Silicone extrusion led strip are divided into silicone hollow extrusion and silicone solid extrusion.

The silicone hollow extrusion light strip has a high light transmittance, the same as the silicone sleeve light strip, but the edge is more resilient, which can better protect the PCB circuit board, and it can be made longer. It has been welcomed by the market as soon as it was launched. As shown in the figure below, the effect after pressing by hand.

The advantages of silicone solid extrusion led strip compared to silicone hollow led strip and silicone sleeve glue filling led strip are obvious. They are more impact-resistant and weather-resistant, not easy to fold and crack, and the length can be more than 50 meters. At present, high-end led strip on the market all use this process, such as silicone neon led strip. High-end silicone solid extrusion neon led strip have low light transmittance, uniform light output on the surface without shadows, no graininess, and beautiful appearance without flaws. Silicone hollow neon led strip(LED flex strip with silicone tube) have high light transmittance, and the light output is almost the same as the bare light board. The graininess will be more obvious, which has a certain relationship with the density of the LED. The high-density LED make the light output more uniform and weaken the graininess.

Disadvantages of led light strip silicone and silicone led neon flex

1. High cost: Compared with ordinary led strip light, silicone led strip and neon flex have higher requirements for materials and processes, so the cost will also increase accordingly.

2. Poor heat dissipation: Each LED generates heat when it emits light, and silicone led strip lights have difficulty in heat dissipation due to packaging problems, so long-term use is likely to cause LED to fail. The light transmittance of silicone can reach about 90%. Luminescence and heat generation are inseparable. The thermal conductivity of silicone is 0.27W/MK, the thermal conductivity of aluminum alloy is 237W/MK, and the thermal conductivity of PVC is 0.14W/MK. Although the heat generated by LED is relatively small, the temperature will affect the service life, so the heat dissipation design is the key to led silicone light strip.

3. Not easy to repair: The design of silicone led strip is constantly improving. Due to the special characteristics of silicone materials and internal wiring of led strip, if there is a problem and it needs to be repaired, it will be relatively troublesome.

Precautions for repairing LED strip silicone

1.Anti-static: LED is an electrostatic sensitive component. Anti-static measures must be taken during maintenance. Anti-static soldering irons must be used. Maintenance personnel must also wear anti-static rings and anti-static gloves.

2.Continuous high temperature: LED and FPC, two important components of LED led strip, cannot withstand high temperatures continuously. FPC will bubble under continuous high temperatures, causing the LED light strip to be scrapped. LED cannot withstand high temperatures continuously, and long-term high temperatures will burn out the chip. Therefore, the soldering iron used for maintenance must be temperature-controlled, the temperature must be within a safe range, and the soldering iron should not stay on the LED pin for more than 10 seconds.

Through the above content, I believe you have a more comprehensive understanding of silicone led light strip. When choosing, you need to make a trade-off based on your needs, and comprehensively consider factors such as cost, usage scenarios, and quality. I hope this information can help you better choose and use silicone strip lights and silicone led neon flex.
