Specification of 95% Alumina Substrate Aluminum Oxide Al2O3 Ceramic Plate for LED Applications

This ceramic plate is made from 95% alumina. Alumina is aluminum oxide. It’s written as Al2O3. This material is very important for LED lights. It acts as a base or substrate. The plate helps manage heat effectively. LEDs create heat during operation. Too much heat damages LEDs. This plate draws heat away efficiently. It keeps the LEDs cooler. Cooler LEDs last longer. They perform better too. This is crucial for high-power LED systems.

The plate is very strong mechanically. It resists breaking under pressure. This strength protects the LED components. It ensures reliability over time. The material is also very hard. It resists scratches and wear well. This durability is important for long life.

Electrically, alumina is an excellent insulator. It does not conduct electricity. This prevents short circuits. It keeps the electrical parts safe. You can use it safely in circuits. The plate isolates heat electrically too. This combination is ideal for electronics.

Thermal conductivity is a key feature. For 95% alumina, it’s quite high. It moves heat quickly from the LED chip. This prevents overheating spots. Good heat dissipation improves LED efficiency. It also stabilizes light output. The plate handles high temperatures well. It won’t degrade easily under heat.

The surface is usually very smooth. It might be polished or lapped. This flatness is necessary. It allows for precise mounting. LEDs and circuits attach cleanly. Good surface quality ensures strong bonds. It helps thermal interface materials work best.

This alumina substrate suits demanding LED applications. Examples include high-power lighting. Automotive headlamps use it. Street lights benefit from it. Industrial lighting systems need it. It supports stable, long-lasting LED performance. It manages the critical heat issue effectively. The plate is a reliable foundation for modern LED technology.

Applications of 95% Alumina Substrate Aluminum Oxide Al2O3 Ceramic Plate for LED Applications

LEDs need good heat management. High-power LEDs create heat. Too much heat lowers performance and shortens life. Alumina ceramic plates solve this. They transfer heat away from the LED chip. This keeps the LED cooler. Cooler LEDs work better and last longer.

Alumina is electrically insulating. It stops electricity from going where it shouldn’t. This is vital for safety. It prevents short circuits. The circuit traces sit directly on the plate. This allows for compact designs.

The plate is physically strong. It holds the LED chip firmly. It protects the chip from vibrations and shocks. Alumina handles high temperatures well. It doesn’t warp or crack easily. This makes it reliable for tough conditions.

Manufacturers print circuits onto the plate. They use special thick-film materials. These circuits connect the LED chip to power. The alumina base supports this circuit layer. It provides a stable, flat surface. This ensures good electrical connections.

Alumina plates work in many LED products. They are common in street lights. They are used in car headlights. You find them in stadium lighting. High-power industrial lights use them too. Any bright LED needing heat control benefits.

The plates offer a stable base. They manage heat effectively. They provide electrical safety. They support the circuit layout. This combination makes them essential. They are a key part of modern, powerful LED systems.

5 FAQs of 95% Alumina Substrate Aluminum Oxide Al2O3 Ceramic Plate for LED Applications

People often ask about alumina ceramic plates for LEDs. What exactly are they? These plates are flat sheets made mostly from aluminum oxide. They serve as bases for mounting LED chips and circuits. The material handles high temperatures well. It also conducts heat efficiently.

Why pick alumina plates for LED projects? LEDs create heat when lit. Too much heat damages LEDs over time. Alumina plates pull heat away from the LED chips. This keeps the LEDs cooler. Cooler LEDs last longer and work better. The plates also stop electricity from leaking where it shouldn’t. This protects the circuit.

What does “95%” mean? It tells us the purity. The plate is 95% pure aluminum oxide. The rest is other materials added during making. Higher purity means better heat transfer. But it also costs more. 95% is a good balance. It gives strong performance for the price.

What are the main benefits? These plates manage heat superbly. They stop electricity from flowing through them. They are very hard and resist wear. They don’t change shape much under heat. They handle high voltages safely. They last a long time under tough conditions.

How thick should the plate be? Thickness matters. It depends on your needs. Thicker plates manage more heat. They are also stronger. But they add weight. They might cost more. Thinner plates are lighter and cheaper. They might not handle as much heat. Talk to us about your project. We help find the best thickness for you.
