Compact backlighting chip LEDs boost output

May 11, 2021  Stephen Law

ROHM SEMICONDUCTOR CSL0901/CSL0902 LED series are compact, high-output, surface-mount LEDs designed with molded lenses to optimize intensity. Product series includes 18 devices, featuring standard brightness and the high brightness CSL0902 series. LEDs are optimized for uses in industrial, medical and automotive systems. Products target applications that require high reliability at the component level, such as developing the first high-brightness, silver-free LEDs to prevent sulfuration, which is one of the leading causes of aging. The automotive-grade products ensure high reliability in vehicle instrument clusters which operate under harsh environments. The light source position is improved from 0.18mm in standard products to 0.49mm, reducing light leakage. Size has also been reduced by approximately 18x compared to conventional reflector-type LEDs.
