Ecodesign regulation information:

Intended for use with LED modules.
The forward voltage of the LED light source shall be within the defined operating window of the control gear in all operating conditions including dimming if applicable.

Separate control gear and light sources must be disposed of at certified disposal companies in accordance with Directive 2012/19/EU (WEEE) in the EU and with Waste Electrical and Electronic Equipment (WEEE) Regulations 2013 in the UK.

For this purpose, collection points for recycling centres and take-back systems (CRSO) are available from retailers or private disposal companies, which accept separate control gear and light sources free of charge. In this way, raw materials are conserved and materials are recycled.

Outdoor constant current DALI NFC LED drivers are advanced, weatherproof (typically IP65-IP67) lighting controllers designed for harsh environments. They allow precise, contactless setting of output current, DALI addresses, and dimming curves via NFC, often providing deep dimming (down to 0.01%) and robust protection against overcurrent and short circuits.

Key features and benefits of these drivers include:

NFC Programming: Allows quick configuration of operating current and DALI parameters (address, groups, scenes) using a smartphone or NFC tool, simplifying on-site setup and reducing inventory.

DALI-2 Compatibility: Enables seamless integration into intelligent lighting systems, offering fine control, monitoring, and addressability.

Constant Current (CC) Output: Ensures consistent light levels by regulating output current, essential for high-power exterior LED fixtures.

Outdoor Rated: Designed with high IP ratings to withstand moisture and temperatures common in exterior applications.

Deep & Smooth Dimming: Supports modern dimming protocols like amplitude/CCR dimming, achieving flicker-free light output down to very low levels.

Protection Features: Built-in protection against overheating, short circuits, and overloading to increase lifespan.

Constant Lumen Output (CLO): Many models offer CLO functionality to maintain stable brightness throughout the life of the LED.

These drivers are frequently used in outdoor applications such as street lighting, architectural lighting, and area lighting, where remote management and high reliability are required.

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.
