Constant current LED drivers with leading and trailing edge compatibility are specialised power supplies that regulate current to LEDs while allowing you to control brightness using standard domestic dimmers. They ensure stable, flicker-free dimming across different dimmer switch technologies.

Here is the breakdown of how these technologies work and why they are paired together:

1. Constant Current (CC) vs. Dimming

Constant Current: LEDs are current-driven devices. A CC driver provides a fixed electrical current (e.g.350mA or 700mA) regardless of how the voltage changes in the circuit. Because LEDs have varying voltage drops as they heat up, a constant current ensures the light output remains stable and the LEDs don’t overheat or degrade prematurely.

Wiring Setup: CC drivers require LEDs to be wired in a series so that the exact same amount of current passes through every light in the chain.

2. Leading Edge vs. Trailing Edge

Traditional wall dimmers control light by “chopping” the AC power sine wave, effectively reducing the total power sent to the light. The difference lies in where they chop the wave:

Leading Edge (Triac): These are older, traditional dimmers designed for incandescent bulbs. They cut the power wave at the beginning (leading edge) of every AC cycle. Because they can cause sharp electrical spikes, they often result in flickering or buzzing when used with delicate LED drivers.

Trailing Edge: These are modern, electronic dimmers. They cut the power wave at the end (trailing edge) of the AC cycle. This creates a much smoother power flow, making them quieter, more precise, and highly recommended for modern LED drivers.

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.
