scope:

This document defines the following roadway and area lighting equipment, which may be physically and electrically interchanged to operate within established values:

a. A locking type 4-pin Luminaire Extension Module (LEX-M),

b. A locking type mating 4-pin Luminaire Extension Receptacle (LEX-R),

c. A Luminaire Extension Cap (LEX-C),

Notes:

Figures 1.1A, 1.1B, and 1.1C show informative 3D-model renderings of these components.

Figure 1.6 gives an overview of a Luminaire with a LEX-R, LEX-M, or LEX-C.

The equipment in 1.1 is primarily intended for outdoor application, although it may also be used indoors.

The equipment in 1.1 provides mechanical and electrical specifications for the interfaces between a LEX-M (sensor/communication module) and LEX-R (electrical part of LED luminaire) using a voltage up to 60 V dc max.

The LEX-C is used to cover LEX-R in situations where no LEX-M is being used. In this case, the mechanical specification for the interfaces between a LEX-R and LEX-C is provided.

The equipment in 1.1 is a plug-and-play interface used with outdoor or indoor luminaires to add connectivity and/or sensing functions. The plug-and-play interface supports future system and service upgrades. Protocol for plug and play interfacing shall be compliant with DALI and Digital I/O between 7 and 30V dc (2A maximum).

Outside of Scope:

a. Modules directly connected to the mains

b. The functionality of the actual sensor/communication module

c. The mounting method of the receptacle to the luminaire, including anti-rotation means
