Adhesives & Sealants for LED Lights Applications

LED Bulbs

Adhesives and sealants are essential in LED bulb assembly, enhancing durability, heat management, and protection from environmental factors. They are used to bond structural parts, secure electronics, and seal against dust and moisture.

Adhesive and Sealant Applications in LED Bulbs

Heat Sink Bonding

Used to attach the LED chip to the aluminum heat sink, ensuring efficient thermal transfer and performance.

Lens and Cap Fixation

Applied to bond the plastic or glass diffuser to the bulb body, ensuring structural stability and optical clarity.

PCB Mounting

Adhesives are used to secure the printed circuit board inside the bulb, maintaining internal alignment and mechanical integrity.

Moisture and Dust Sealing

Sealants are applied around housing joints to protect internal components from environmental exposure.

Internal Component Stabilization

Used to hold wires, resistors, and small components in place during operation and transportation.

Adhesive and Sealant Applications in LED Tube Lights

End Cap Bonding

Used to fix end caps securely to the tube body, maintaining electrical contact and structure.

Diffuser Attachment

Adhesives are applied to bond the light diffuser or cover to the tube for consistent light dispersion and protection.

PCB or Strip Fixation

Bonding of LED strips or PCBs to internal aluminum channels ensures heat dissipation and vibration resistance.

Water and Dust Sealing

Sealants are applied for IP-rated protection, especially in moisture-prone environments.

Wire Management and Component Holding

Used to fix wires and internal components, preventing movement and wear over time.

LED Tube Lights

In LED tube lights, adhesives and sealants support structural bonding, thermal management, and environmental protection. Their use helps extend product life and ensures consistent light quality.

LED Drivers

Adhesives and sealants in LED drivers ensure electrical insulation, thermal control, vibration resistance, and protection of sensitive electronic components.

Adhesive and Sealant Applications in LED Drivers

Component Fixation

Used to secure capacitors, coils, and transformers to the PCB, protecting them from vibration and movement.

Potting and Encapsulation

Sealants are used to encapsulate the entire driver or specific components for insulation, thermal management, and environmental protection.

Enclosure Sealing

Applied at casing joints to prevent ingress of dust, moisture, and other contaminants.

Heat Sink Attachment

Adhesives bond power components to heat sinks, optimizing thermal conductivity and improving driver lifespan.

Wire and Terminal Support

Fixation of terminal blocks and cable entries to prevent mechanical stress and enhance durability.
