Colour mixing reduces variations with RGB chip LED

Rohm has developed an RGB chip LED for automotive interiors, such as function and status indicators in instrument clusters, CID (Centre Information Displays) and accent lighting for footwells and door handles.

The SMLVN6RGBFU uses its in-house technology to improve the colour mixing for more accurate colours by precisely controlling the luminous characteristics of the RGB elements in the LED.

RGB chip LEDs that emit light at a specified colour require precise control of the wavelength and brightness of the mounted red, green, and blue (RGB) elements individually as well as methods to enhance color-mixing capability. Rohm has minimized element colour variation over general products by using a vertically integrated production system from the element fabrication stage.

At the same time, original element colour mixing control technology reduces the variations caused by colour mixing that tends to occur in RGB chip LEDs, resulting in more accurate colours for automotive interiors. The company also supports detailed colour matching tailored to user specifications with the chromaticity simulation system.

The SMLVN6RGBFU sets adjustment coefficients for each chromaticity rank while providing calibration support to bring the colour closer to the desired target. This new RGB chip LED and high-accuracy chromaticity simulation allows precise colour matching.
