Sanna158 AC IoT

Sanna158 is an AC LED module developed for professional luminaires where long-term stability, predictable behaviour and system compatibility are essential. The module is intended for applications in which light output, power consumption and colour performance must remain explainable and verifiable over time. Electrical and thermal characteristics are evaluated under defined operating conditions, with emphasis on repeatable behaviour across mains voltage and temperature.

Mechanical design and integration

Sanna158 is a round LED light engine designed for luminaire integration in pendant and downlight applications. The module features a central opening for cable routing and defined connection points to support structured assembly. Depending on configuration, the module can be combined with control interfaces such as DALI, Casambi or equivalent systems. Variants for IoT-based applications include an electrically isolated thermal interface, supporting use in Class II luminaires.

Light quality and colour stability

The optical performance of Sanna158 is developed with emphasis on colour stability and maintained luminous flux over time. Binning, thermal behaviour and ageing characteristics are controlled to support predictable chromaticity under defined operating conditions. Measured colour stability data is provided for system-level evaluation.

Dimming and control behaviour

Sanna158 supports controlled dimming using phase-cut dimmers and digital control interfaces, depending on configuration. When operated with a DimIn module, dimming is achieved through highfrequency analog current regulation based on amplitude modulation, avoiding PWM and enabling low visible modulation and predictable electrical behaviour across the dimming range.

System compatibility and smart lighting

Sanna158 is designed for integration into professional lighting systems where interaction with building automation, energy management and documented control architectures is required. For system-level considerations related to dimming behaviour, energy performance and daylightoptimized control strategies, refer to the document “Analog Dimming in Daylight-Optimized Buildings” and the DimIn system documentation. Smart lighting compatibility Sanna158 is designed to be used in professional lighting systems where integration with control and automation infrastructure is required. Depending on configuration, the module can be combined with DimIn interface modules supporting control standards such as DALI, Casambi or analog dimming.

DimIn modules are connected directly to the LED module and enable system-level control without the need for external drivers. Control interfaces are selected by module configuration and are intended to support documented and traceable lighting system architectures.

For detailed information on DimIn functionality, control behaviour and system integration, refer to the DimIn datasheet and related documentation.
