DALI Constant Current NFC LED drivers are advanced, addressable lighting control units that power LED fixtures (300mA–850mA+) and support DALI-2/DT6/DT8 protocols for smart building automation. NFC (Near Field Communication) technology allows precise, wireless configuration of current, DALI addresses, and dimming curves via a smartphone app, enabling, in some cases, ultra-deep dimming down to 0.01%.

Key Features and Benefits

NFC Programming: Allows for setting output current in 0.1mA or 1mA steps, reducing inventory needs as one driver fits multiple fixtures.

DALI-2 Compatibility: Compatible with IEC62386-101/102/207 standards, supporting DALI DT6 (single color) or DT8 (tunable white).

Performance: Features flicker-free, smooth dimming (100% down to 0.01% or 1%).

Protection & Lifetime: Includes automatic recovery for short-circuit, overload, and over-temperature protection. They often feature long lifespans (up to 100,000 hours).

Functionality: Supports Constant Lumen Output (CLO), corridor functionality (CD), and configurable fade times.

Application and Usage

Industries: Suitable for indoor, office, and commercial lighting, including downlights, spotlights, and panels.

Installation: Often feature compact designs with built-in cable clamps, suitable for Class I, II, or III fixtures.

Setup: Configuration is typically done by scanning the driver with an app (e.g., SR NFC tool) to adjust parameters, even without mains power.

OSRAM Licht AG is a German company that makes electric lights, headquartered in Munich and Premstätten (Austria). OSRAM positions itself as a high-tech photonics company that is increasingly focusing on sensor technology, visualization and treatment by light.[3] The company serves customers in the consumer, automotive, healthcare and industrial technology sectors.[4] The operating company of OSRAM is OSRAM GmbH.

Osram was founded in 1919 by the merger of the lighting businesses of Auergesellschaft, Siemens & Halske and Allgemeine Elektrizitäts-Gesellschaft (AEG). Osram was a wholly owned subsidiary of Siemens AG from 1978 to 2013. On 5 July 2013, Osram was spun off from Siemens, and the listing of its stock began on Frankfurt Stock Exchange on 8 July 2013.[5] Osram’s business with conventional light sources was spun off in 2016 under the name Ledvance and sold to a Chinese consortium.[6]

After a bidding war[7] with Bain Capital, Osram was taken over by Austrian company AMS in July 2020.[8][9][10] Since then, the company has operated under the name AMS Osram.[11]

The name is derived from osmium and Wolfram, German for tungsten. Both elements were commonly used for lighting filaments at the time the company was founded.

In 2020 ams AG acquired the German lighting, LED, and opto-semiconductor manufacturer OSRAM. Since then, the company operates under the name ams OSRAM.

The ams OSRAM portfolio includes light emitters, sensors and CMOS ICs with embedded software solutions as well as lighting systems and specialty lamps for automotive, industrial and entertainment applications. The company mainly address the automotive, industrial and medical markets, as well as selected fields of consumer electronics.
