Zhaga's Progress

Approved Zhaga Specifications

In February 2011, the Zhaga Consortium approved the first light engine specification.

1. Socketable LED light engine with integrated control gear

This specification describes the interfaces of a downlight engine. These specifications are currenly available for review by members only. The specification will be made available for public download later this year.

2. Spotlight engine with separate control gear

In June 2011, the Zhaga Consortium approved the second light engine specification. This is the specification for the interfaces of a spotlight engine:

Here you can see some of the prototypes that were developed to test the specifications:

The control gear of this spotlight engine is located in a separate housing.

3. Socketable LED Light Engine with Separate Electronic Control Gear

In September 2011, the Zhaga Consortium approved the third light engine specification. This specification describes the interface of a socketable light engine. The control gear of this spotlight engine is located in a separate housing.

4. Compact a compact socketable LED Light Engine with integrated electronic control gear

In December 2011, the Zhaga Consortium approved the fourth light engine specification. This specification describes the interface of a socketable light engine.

5. Common interface definitions

In December 2011, the Zhaga Consortium approved a specification that defines aspects that are common in multiple Zhaga interface specifications, such as:

  • common definitions
  • the mechanical interface of separated electronic control gear
  • the generic aspects of the thermal interface

Zhaga specifications ready for approval

In January 2012, Zhaga did not have any specifications in the approval phase.

Specifications under development

In November 2011, the Zhaga consortium was discussing the interface specifications of several light engines.

Light engines in phase 2:

At this moment Zhaga has one specification in the merger phase:

  • A light engine with linear module (non-socketable with separate control gear) for indoor application.

Light engines in phase 3

Several light engines have reached the specification development phase:

  • A streetlight engine (non-socketable with separate control gear)
  • A circular, 85mm, downlight engine for high lumen output (socketable with integrated control gear)
  • A light engine with rectangular LED module for indoor use, with separate control gear. One indoor luminaire may contain several of these rectangular modules and one control gear.

Task Force Dimming

Zhaga established a task force to study how the dimming behavior of LED Light Engines can be specifies such that the light engines become interchangeable in their dimming behavior. The task force's first priority is phase cut dimming.

Zhaga does not plan to create a Zhaga specfication for dimming, but prefers to reference an existing specification. We cooperate with NEMA to establish a dimming interface standard that is suitable for LED Light Engines.
