Book 15:
Rectangular LED modules for use with lens arrays

Book 15 defines a family of rectangular LED modules that are intended to be used with lenses or arrays of lenses (also known as lens plates).


The modules require a separate LED driver (electronic control gear), and usually will be mounted on a heat sink.


The specification defines several attributes of the LED modules, to enable accurate alignment with the lenses, but the lenses themselves are NOT defined in this specification.


Book 15 modules with lenses are typically used for outdoor lighting applications, including roadway, pathway and outdoor-area lighting.
