Interchangeable light sources The lighting industry is used to work with standardized light sources E27, G5, G9, 15 April 2012 4
LED light sources are not interchangeable today Most LED light sources are not interchangeable, until now Typical differences are: fit with heat sink (2, 3, or 4 screws) size of the heat sink size of the light emitting surface height of the light emitting surface Problem: Change LED => Change heat sink & reflector in luminaire 15 April 2012 5
Zhaga: interchangeable LED light sources Zhaga makes LED light sources interchangeable The main parameters are: Mechanical and thermal fit with the heat sink Size of the light emitting surface Height of the light emitting surface Photometric properties of the light emitting surface 15 April 2012 6
The six Zhaga interface specifications Book 2: Socketable LLE with integrated ECG Status: finalized February 2011 Book 3: Spot LLE with separated ECG Status: finalized July 2011 Book 4: Street Light Engine Status: finalized in March 2012 Book 5: Socketable LLE with separate ECG Status: finalized September 2011 Book 6: Socketable LLE with integrated ECG Status: finalized December 2011 Book 7: Office LLE with separate ECG Status: finalized in April 2012 15 April 2012 7
What are interface specifications? Zhaga specifies the outside properties of the light source: mechanical fixation thermal behavior electrical properties photometric properties The inside is not specified. Manufacturers can make their own internal engine design. Innovation continues inside this 'Black Box. 15 April 2012 8
Not performance or quality only interchangeability Zhaga specifies the minimum needed to achieve interchangeability Zhaga does not specify quality and performance aspects, such as: life time, color stability, energy efficiency, or safety Zhaga enables product differentiation and application-specific trade-off between cost and performance 15 April 2012 9

Challenges for manufacturers in the LED market: Chaotic market rapid development, proprietary form factors and interconnects Lack of standardization or agreed-upon specifications Uncertain customer base Patent mine field 15 April 2012 15
Challenges for manufacturers in the LED market: Conflicting/confusing information Unproven claims Inability to interchange products makes it difficult to Upgrade products Source replacement parts Interconnect different parts of a system Merge old technology with new technology + + =?? 15 April 2012 16
Benefits of Zhaga Membership: Companies at every functional tier of the industry participate The best Solid State Lighting expertise in the world is gathered in one place Open communication no proprietary systems Equality of influence 1 vote for each participating company One common goal for all - interchangeability! 15 April 2012 17
The fact that products are made to be interchangeable does not mean that everyone will build the same thing. 15 April 2012 18
The endgame. For Manufacturers Leviton can design its components and subsystems to interact effectively with other Zhaga certified products to create highly effective and versatile working systems For Customers Users of Zhaga certified products can be confident that those products will perform properly when used with other Zhaga certified products regardless of manufacturer 15 April 2012 19
Zhaga Book 3: Spot Light Engine Dawson Liu President, Lustrous Technology
Introduction of Zhaga Spot Light Engine
System Overview Book 3 of the System Description Zhaga defines a Spot LED Light Engine with separate Electronic Control Gear and a Luminaire 15 April 2012 22
Mechanical Interface LED Module Geometry The spot light engine parameters define only maximum outlines, meaning that LED Module may also be smaller if technically feasible Only the features relevant to interchangeability like the screw holes and their positions and the OCA are specified with bothsided tolerances 15 April 2012 23
Mechanical Interface LED Module Connection An electrical interconnect should be placed symmetrically at the LED Module X axis This limitation is to ensure the interchangeability of the LED Module y X 15 April 2012 24
Mechanical Interface Optical Contact Area (OCA) The LED Module have a physical surface of the housing denoted as OCA The position and dimensions of this OCA are depends on the Light Emitting Surface (LES) LES OCA 15 April 2012 25
Mechanical Interface Locking Ring System (LRS) The Locking Ring System is an optional accessory that enables toolless mounting of the module 15 April 2012 26
Photometric Interface Lighting Emitting Surface (LES) The LES for spotlight application shall be described by a 2- dimensional circle having the smallest possible diameter In the case of a diffuse cover covering the LEDs, the LES shall be described by the functional area of the diffuse cover 15 April 2012 27
Photometric Interface Luminous Flux The Luminous Flux of an LLE shall be in one of the category listed in Table as below (Total 9 categories) The operating condition shall follow the requirement of the Zhaga specification 15 April 2012 28

Summary
Benefits from Zhaga How can luminaire manufacture beneficial from Zhaga Spot Light Engine? Unify the mechanical specification of LLE which provides quick installation for any LED light source in same luminaire Easy to choose different flux category for different purposes Thermal issue can be solved by the interoperability check Fast installation makes the fabrication easier Clear test procedure make the LLE with Zhaga logo sustain its reliability By giving standardize dimension, luminaire manufacture can have fully focus on their design 15 April 2012 34
