What is a Light Engine?

An LED light engine is the combination of an LED module and the associated control gear.

We treat LED light engines as a black box, with defined interfaces that do not depend on the type of LED technology used inside the light engine.

The Zhaga specifications only define the outside of LED light engines.

Electronic Control Gear included

A light engine can have an integrated control gear. That means that the control gear is integrated in the same housing that contains the LEDs. 

An LED Light Engine may also have LEDs and Control Gear in separate housings. These housings will then be connected with a cable. For the purpose of Zhaga, this cable is considered inside the Light Engine. It is part of the black box inside of Zhaga Light Engine.
