ROHM's New 1608-Sized High Brightness Single Rank Chip LEDs
75% less brightness variation vs. conventional products contribute to improved performance and reduced design load
KYOTO, Japan and SANTA CLARA, Calif., Dec. 15, 2015 /PRNewswire/ -- 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 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%. This makes it possible to provide a single rank of brightness (a rarity in the industry), significantly lightening 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 (1.6mm x 0.8mm). The LEDs are also AEC-Q101 qualified, making them suitable for applications demanding increased reliability such as automotive systems.
Key Features
1．Single rank capability eliminates brightness variations
Conventionally, customers ordering a specific brightness level would receive 4 different brightness ranks due to limitations in production technology. In contrast, leveraging its industry-leading comprehensive, integrated manufacturing process allowed ROHM to achieve breakthrough accuracy that reduces brightness variations by 75%, making it possible to provide single-rank products that provide unmatched consistency in end-applications while significantly reducing design load.
2. Class-leading brightness in the 1608 size
Complete redesign and optimization of the LED element have enabled the brightness to be increased by up to 3 times compared with conventional LEDs, delivering industry-leading brightness in the 1608 size (1.6x0.8mm).
