Overview of Zhaga Books

The Zhaga interface specifications, known as Books, each cover different types of LED light engines (LLEs).

The main features of each Zhaga Book are summarized in the following presentation:

Introduction to Zhaga Books

As well as browsing the Book library, you can select Books according to the shape of light-emitting surface (LES), whether the driver is integrated or separate, or whether the light source is socketable or not.

Books

Book 1 - Common information and definitions

Book 1 defines features that are common in multiple Zhaga interface specifications, such as common definitions; the mechanical interface of separated LED drivers (electronic control gear); and the generic aspects of thermal interfaces.

Book 2 - Socketable, circular LED light engine with integrated driver

Book 2 defines the interfaces of a socketable, circular LED light engine (LLE) with an integrated LED driver (electronic control gear).

The LLE has a round drum shape with maximum dimensions of 70.2 mm diameter and 45 mm height. It has a circular light-emitting surface with a typical diameter of 59 mm, and a PHJ65d type base.

Book 3 - Circular LED module with separate driver

Book 3 defines the interfaces of LED light engines (LLEs) comprising a circular, non-socketable LED module with a separate LED driver (electronic control gear).

The circular LED modules in Book 3 have a typical diameter of 50 mm and a maximum height of 7.2 mm. There are four LLE categories in Book 3, which are defined by the diameter of the circular light-emitting surface (LES).

Book 4 - Rectangular LED module with separate driver

Book 4 defines the interfaces of high-intensity LED light engines (LLEs) comprising a rectangular, non-socketable LED module with a separate LED driver (electronic control gear).

For applications that need a high-intensity light source, such as outdoor and industrial lighting.

Book 8 - Socketable, circular LED light engine with integrated driver

Book 8 defines the interfaces of a socketable, circular LED light engine (LLE) with an integrated LED driver (electronic control gear).

The LLE has a round drum shape with maximum dimensions of 95 mm diameter and 45 mm height. It has a circular light-emitting surface (LES) with a diameter in the range of 59 mm to 71 mm, and a PHJ85d base.

Book 9 - LED module with ring-shaped light-emitting surface and separate driver

Book 9 defines the interfaces of LED light engines (LLEs) comprising a non-socketable LED module with a ring-shaped light-emitting surface (LES) and a separate LED driver (electronic control gear).

The specification describes small, mid-power LED modules that have diameters of 12 mm or 25 mm for the ring-shaped LES.
