1608Sized High Brightness Single Rank Chip LEDs
ROHM has recently announced the availability of high accuracy single-rank 1608-size high-brightness chip LEDs optimized for a wide variety of applications, from industrial equipment and consumer devices to automotive systems.
The need to reduce brightness variations is increasing as a greater number of applications and devices, particularly in the automotive and industrial sectors, are demanding improved consistency when configuring multiple LEDs side-by-side. However, up to now it has been difficult to minimize brightness variations during the manufacturing process. Conventionally, users were able to only narrow down the number of ranks from around 4 to 2-3, which still required sorting and the use of different resistors to match each rank, increasing the number of man-hours re-quired along with inventory management. In response, the SML-D15 series was developed using a comprehensive, highly integrated manufacturing system (from device fabrication), allowing ROHM to surpass the limits of conventional LED production. As a result, high-accuracy brightness is achieved and brightness variations reduced by 75%. This makes it possible to provide a single rank of bright-ness (a rarity in the industry), significantly lightening design load.
