Reduced design load and improved application performance with a luminous intensity deviation of 1/4 compared to existing products

RHOM has developed and released the "SML-D15 Series," a single-rank 1608 size high-brightness chip LED suitable for display panels of industrial and consumer devices, as well as automotive devices such as car audio and instrument panels.

In automotive devices such as instrument panels and car navigation systems, as well as industrial equipment that uses multiple LEDs in a row, there is a growing demand for reducing luminous intensity variation to improve application performance.

However, generally, LEDs experience some variation in luminous intensity during the manufacturing process. Previously, to suppress this variation, it was necessary to select a deliverable luminous intensity rank by specifying 2 to 3 luminous intensity ranks from about 4 preset luminous intensity ranks, or to adjust directly using a resistor according to the delivered luminous intensity rank, which resulted in an increase in design effort.

The LED "SML-D15 Series" has succeeded in stabilizing luminous intensity by significantly reducing the luminous deviation, which was a limitation of conventional LED manufacturing, through strict luminous intensity settings at the device manufacturing stage via Roam's consistent production system. By realizing high precision with a luminous intensity deviation of 1/4 compared to conventional ones, it enables single-rank supply, which is rare in the industry, and contributes significantly to resolving luminous intensity deviation and reducing load in each application.

In addition, through the review and optimization of LED light-emitting elements, we have achieved up to three times higher brightness compared to our existing products, boasting the highest level of brightness in the industry for the 1608 size (1.6×0.8mm). In addition, by complying with AEC-Q101, the reliability standard for automotive parts, we meet customer requirements in terms of quality as well.
