Sapphire LED substrate

Sapphire LED substrate (substrate material for LED chips)

LED chips are the core components of LED lights, and their performance directly affects the luminous efficiency and lifespan of LED lights. Sapphire high-strength glass has become an ideal substrate material for manufacturing LED chips due to its high transparency, high thermal stability, and chemical stability. By growing LED epitaxial layers on it, high-performance LED chips can be produced, which are widely used in fields such as lighting and display.
