DALI linear constant current LED drivers are advanced, addressable lighting controllers designed for professional, commercial, and, smart home applications. They provide flicker-free, 0–100% (or deep 0.01%) dimming using DALI-2 (DT6/DT8) protocols, allowing for individual control or grouping of lights, often featuring NFC programmability for precise current adjustment (e.g., 100-1050mA) and long, slim, IP20-rated designs for linear fixtures.

Key Features & Advantages

DALI-2 Compatibility: Certified for reliability within modern Digital Addressable Lighting Interface (DALI) systems, allowing for bidirectional communication for control and monitoring.

Constant Current (CC) Output: Ensures consistent brightness for LEDs by supplying a steady current, typically adjustable via DIP switches or NFC, ranging from 250mA to 1000mA+.

NFC Programmability: Many modern drivers, such as those from Sunricher and KGP, allow for setting output current, DALI addresses, dimming curves (linear/logarithmic), and fade rates via an NFC smartphone app.

Linear Form Factor: Designed to fit into slim, linear luminaires or profile lighting.

High-Quality Dimming: Capable of deep, smooth, flicker-free dimming down to 0.01%, often supporting PWM (Pulse Width Modulation).

Safety & Reliability: Typically includes built-in protection against short circuits, overloads, and overheating, often with a 5-year warranty.

Common Applications

Commercial Lighting: Office, retail, and architectural spaces requiring flexible,, addressable lighting control.

Linear Fixtures: Perfect for LED strip, channel, or Batten light fixtures.

Tunable White (DT8): Some models, such as from LTECH, support DALI DT8 to control CCT (1000K-10000K).

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
