Why should the LED drive power supply use potting silicone? What is its role?

The LED driver power supply is a device that converts the power supply into a specific voltage and current to drive the LED to emit light. It is usually composed of a switching controller, inductor, switching components (such as MOSfet), feedback resistance, input filter, output filter and other core components.

Electronic potting silicone is a low-viscosity, two-component, condensed silicone sealant that can be quickly cured at room temperature, and its main role is to seal the gap between the circuit board and electronic components to prevent moisture, oxidation, vibration and other environmental factors from invading the circuit board, thereby damaging electronic components. At the same time, it can also improve the insulation performance of the circuit board to prevent circuit short circuit and leakage.

When selecting the right electronic potting silicone, several factors need to be considered: curing time, viscosity, temperature and humidity. Different types of electronic potting silicone have different curing times, viscosity and sensitivity to temperature and humidity. Selecting the right parameters can ensure the sealing effect between the board and the components.

Here to recommend flame retardant thermal conductivity of electronic potting silicone TS8833.

TS8833 is a thermal potting silicone developed by SHENZHEN TENSAN CO., LTD, which can effectively improve the moisture-proof, insulation and vibration resistance of components and printed circuit boards; Its high and low temperature resistance, stress release, material strength, flame retardant characteristics ensure the long-term reliability of the component. Suitable for electronic modules, power supplies, sensors, solar cells, LED drive power/modules, transformers and other occasions

The role of TS8833 electronic potting silicone in the LED driver power supply is mainly reflected in the following aspects:

1. Protection: The LED drive power supply may be affected by the external environment during operation, such as humidity, dust, high temperature, etc. The electronic potting-sealing silicone has good sealing performance, which can isolate the LED driver power from the external environment, thereby protecting the internal components from damage and improving the stability and reliability of the drive power.

2. Heat dissipation performance: LED drive power will produce a certain amount of heat during the working process, and the accumulation of heat may lead to overheating of the internal components, affecting its performance and life. Electronic potting silica gel has good thermal conductivity, can effectively transfer heat to the radiator, reduce the temperature of the drive power supply, and extend the service life of the component.

3. Shock and vibration resistance: The LED drive power supply may be affected by shock and vibration during transportation and installation, resulting in loose or damaged internal components. Electronic potting silicone has good flexibility and adhesion, which can effectively fix components and reduce the impact of shock and vibration on the drive power supply.

4. Insulation performance: electronic potting silicone has good insulation performance, which can prevent short circuit and leakage inside the drive power supply and improve safety performance.

5. Space saving: electronic potting silicone has good fluidity and fillability, which can make the overall volume more compact while filling the gap of the drive power supply, which is conducive to the design and assembly of the product.

6. Environmental protection and no pollution: electronic potting silicone is environmentally friendly and pollution-free, friendly to the human body and the environment, in line with the development trend of green environmental protection.
