ROHM Semiconductor Presents 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, featuring a height of 1.1mm. Both units are capable of 1.8cd (white).
RGB 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 often results in non-uniform light distribution or LED see-through, where the LED is visible through the object itself.
ROHM solved these issues with the SMLV56RGB1W1 in the thinnest form factor on the market. An industry-leading package height of only 0.6mm has been achieved due to a novel flat frame structure. This makes it possible to configure the LED a longer distance away from the object, enabling uniform light transmission with excellent colour 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 the products.
Key Features
1. High luminance: 1.8cd (when emitting white light)
2. Industry’s thinnest profile (t=0.6mm) ensures superior colour blending and uniformity (SMLV56RGB1W1)
3. Built-in protection diodes prevent damage due to ESD
4. Color sorting performed to minimize variations
