Book 7:

Linear and square LED modules

Zhaga Book 7 defines a family of linear and square LED modules that typically could be used for indoor lighting applications.

The LED modules require a separate LED driver (electronic control gear), and are typically mounted in a luminaire, for example by means of screws. Book 7 LED modules are intended to be mounted and replaced by professionals only.

There are ten LED module categories in Book 7, which are defined by the overall maximum dimensions of the LED modules. The maximum dimensions of the LED modules also indicate the size of the keep-out area in the luminaire.

Rectangular Square
L28W2 - length 280 mm x width 20 mm L6W6
L28W4 L28W28
L28W6 L38W38
L56W2 L56W56
L56W4  
L14W2 - NEW: added in Edition 1.4  

The only restriction on the light-emitting surface (LES) of the LED modules is that all light should be emitted above the upper surface of the module. This provides maximum design freedom with respect to the placement of LEDs on the module.
