Dynamic color effects for colorful interior lighting: OSIRE® 3731 from Osram – now at Rutronik

12/18/2023 Product News

Rutronik is now stocking the intelligent RGB LEDs of the OSIRE® 3731i series from ams OSRAM. The light source has an integrated driver, improved color accuracy, and increased brightness. The open system protocol (OSP) allows serial data communication between hundreds of LEDs to execute almost any color algorithm. Thanks to the combination of intelligent LED and OSP, car manufacturers can implement dynamic interior lighting more cost-efficiently with a simpler architecture, fewer components, and less cabling. The LEDs come in an SMD housing and are available at www.rutronik24.com.

The intelligent RGB components have an embedded IC that contains optical measurement data with set values of 10 mA and 50 mA. An external microcontroller can control each device in a daisy-chain architecture via an open system protocol that allows the controller to read data. This enables the execution of any color algorithm with improved accuracy and homogeneity. The devices are predestined for applications in vehicle interiors that require highly dynamic RGB lighting scenarios and deliver a broad color spectrum and increased brightness for dynamic color effects.

The LEDs require a supply voltage of 5 VDC. The optimum operating temperature is between -40 °C and +110 °C.
