cryscor on 06 Aug 20LED remains the dominant sapphire application. Sapphire substrates are ideal for use in LED applications due to high-temperature resistance, high strength, good electrical insulation, and low dielectric loss. Sapphire substrate in LED lighting helps prevent stray currents caused by radiation from spreading to nearby circuit elements. Its crystal structure also allows LED lights to have a wider beam angle
