Zhaga Book 10 “Circular LED Modules for Spot Lighting” Edition 1.0 March 2017

Book 10 overview Book 10 defines a family of circular LED modules that have a small circular light-emitting surface (LES). Book 10 LED modules can be used with luminaire optics such as lenses and reflectors, and are typically used in spot lighting applications. Optics contact area as mechanical reference Screw mounting holes Book 10 LED module (category D35) Defined LES position and size

Book 10 replaces Book 3 and Book 11 Book 10 contains simplified and harmonized specifications for the LED modules in Book 3 (50mm diameter) and Book 11 (35mm diameter). D35 category (35mm diameter, formerly Book 11) Book 10 LED modules Book 10 LED modules can also consist of LED arrays according to Book 12, in combination with suitable array holders. D50 category (50mm diameter, formerly Book 3)

Book 10 overview The modules require a separate LED driver (electronic control gear), and usually will be mounted on a heat sink. Book 10 LED modules can also consist of LED arrays according to Book 12, in combination with suitable array holders. The LED modules are intended to be installed and replaced by luminaire makers only.

Book 10 module categories 2 LED module categories, defined by maximum diameter Mounting by 2 screw holes Common light-emitting surface (LES) dimension where appropriate Enables small (D35) or large (D50) LES dimensions Same Optics Contact Area (OCA) height Enables compact (D35) or versatile (D50) outer shape Category Maximum module diameter Optics Contact Area Module height D35 35mm 4mm D50 50mm Up to 7.2mm

Further specification details MECHANICAL: The Book defines Maximum outline Mounting hole positions Position, shape and size of light-emitting surface (LES) Optics Contact Area (OCA) ELECTRICAL: Electrical interface compliant with MD-SIG specification PHOTOMETRIC: Specification of LES, luminous intensity distribution, uniformity Refer to Book 1 for requirements for: Flux, CRI, CCT THERMAL: Simple thermal interface based on total thermal power.

Improvements compared to Books 3 and 10 MECHANICAL: Introduction of common demarcation model to describe LED module shape and luminaire keep-outs Inclusion of LED array holders for Book 12 LED arrays Simplification of requirements (outer shape, OCA, inner features) ELECTRICAL: Electrical interface compliant with MD-SIG specification PHOTOMETRIC: Simplification of LES description and testing THERMAL: Common use of simplified thermal model
