The Industry’s Thinnest High-bright RGB LEDs

ROHM Semiconductor GmbH has recently announced the development of two types of high-bright RGB LEDs: SMLV56RGB1W1, featuring a height of only 0.6mm, and the standard-type SMLW56RGB1W1. Both units are capable of 1.8cd (white), making them ideal for gaming devices or spotlighting applications.

RGB LEDs are convenient because they can emit virtually any color, including white, while taking up very little space since the three elements are integrated into a single, compact form factor. This makes them the preferred choice in portable gaming devices and applications requiring high brightness and multiple colors in a small area.

One drawback to high brightness LEDs is the small distance between the LED and target object, often due to the relatively large package height of conventional LEDs (at least 1.4mm). This results in non-uniform light distribution or LED see-through, where the LED is visible through the object itself (see the table to the right).

ROHM solves these problems with the SMLV56RGB1W1. An industry-leading package height of only 0.6mm has been achieved due to a novel flat frame structure. As a result, the distance to the target object is increased, enabling uniform light transmission with excellent blending characteristics.

Both SMLV56RGB1W1 and SMLW56RGB1W1 integrate protection Zener diodes to prevent damage due to ESD, and classification is performed based on white light emission, ensuring little variation in chromaticity for greater uniformity and consistency between products.
