Europe traditionally does not use external controls for individual lamps (lighting fixtures). Of course, there are also projects that will require

the installation of an ANSI standard NEMA base for future use of smart controls. More and more smart street lighting projects in Europe now

specify Zhaga sockets on top of the lamps. The Zhaga-based controller derives from the low-voltage power supply of the LED driver, which

reduces cost, reduces size, and provides reliability because there are fewer electronic components in the controller. Additionally, sensors can

be deployed by adding a second Zhaga socket to the bottom of the luminaire. However, in some cases these sensors must consume very little

power because the auxiliary power used to drive the controller’s LED driver is limited.

In addition to the above functions, we believe that the biggest advantage of Zhaga is that it standardizes the relevant standards. The Zhaga specification defines

the interface requirements between the LED light engine and the LED luminaire. A good interface specification will only define the interaction part between the

luminaire and the light engine, while it should not unnecessarily limit the design of the light engine or luminaire. A good interface specification should allow

innovation in the internal design of the light engine, and at same time it will ensure the stability of the part connected to the luminaire. Meanwhile, Zhaga also

provides standards for the unification of light engines, LED driver design and sensor design. Its important purpose is to facilitate the interchange and compatibility

of products from different manufacturers within the alliance. This can promote innovation and competition in LED lighting applications, and the ultimate

beneficiary will be consumers.

Finally, Zhaga has defined a certification process to accompany its standards in order to build trust in interoperability. Implemented by an independent testing agency,

the certification status of products can be verified against publicly accessible databases and trademarks to prevent abuse.

Advantage:

In some cases, the cost of ownership is lower because the controller is powered by the LED driver in the luminaire.
Provide signals and power for low-power sensors.
The small size controllers may improve the appearance.

There are four pins for low-voltage signaling.
