Single-rank 1608-size HBLEDs reduce brightness variations by 75 percent
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 four to two-three, which still required sorting and the use of different resistors to match each rank, increasing the number of man-hours required 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% which makes it possible to provide a single rank of brightness which lightens design load.
In addition, by optimizing the LED element ROHM was able to improve brightness by up to 3x over conventional products, delivering class-leading brightness in the 1608 size (1.6 mm x 0.8 mm). The LEDs are also AEC-Q101 qualified, making them suitable for applications demanding increased reliability such as automotive systems.
