First Book 20 Control Devices Earn Certification

Zhaga Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication module or control device. Book 20 brings together complementary specifications from the Zhaga Consortium and the D4i specifications from the DALI Alliance. Certified control devices can carry the dual logos of Zhaga and D4i which together indicate interoperability. Osram is the first company which has earned the Zhaga-D4i certification for a number of their control devices.

In the LED luminaire the module or control device connects to the LED driver, and typically provides sensory inputs or enables communication between network components.

The Osram product families QBM D4i Z, QBM D4i LS/PD Z and QBM D4i LS/PD HB Z have been Zhaga-D4i certified and can now carry the Zhaga-D4i certification logo.

This family of devices is equipped with a Qualified Bluetooth Mesh wireless interface, ensuring connectivity to D4i drivers, together with light and presence detection
enabling light harvesting functionalities.

Zhaga Book 20 provides a simple way to add control devices to luminaires by providing a standardized interface between them. The combination of complementary specification for mechanical fit, digital communication, and connection interface ensures interoperability for components from multiple suppliers. This combination helps enable smart luminaires that are easily upgradable to take advantage of the rapid developments in digital networking technology.
