Introduction

3 / 59
This Design-in Guide covers the SLE G6 Spotlight system from Tridonic.
The SLE G6 provides energy efficient lighting solutions with high quality light for retail, catering and other spotlight and downlight
applications.
The system consists of chip-on-board module and mount, chip-on-board module with pre-tinned wires or chip-on-board module
without cable in four versions:
The Design-in guide provides all the information needed to build a luminaire with the SLE G6 Spotlight system and adapt it to the
desired needs.
This includes:
Standard version with different lumen packages and different light colours (2,700 K, 3,000 K, 3,500 K, 4,000 K)_
Three special versions that are optimised for specific applications:_
SLE FOOD:
LED modules specifically for FOOD applications display foods in the very best light – white elements remain white,
colours are more true-to-life and are perceived more intensively. Stronger brown tones for example make baked goods
appear more crispy, and the red of meats is emphasised to greater effect.
_
SLE ART:
This new LED module offers the high quality of light that is needed for displaying high value exhibits. Unique Tridonic
full spectrum technology provides excellent colour rendering. The average value for all the products in the SLE ART
series is CRI 98, a truly impressive figure. And you can also rely on outstanding colour consistency (MacAdam 2) for
your applications.
_
SLE FASHION:
The modern FASHION LED light is ideal for the sparkling display of fashion. The technology conceals several years of
intensive research targeted specifically for lighting in the retail sector. SLE FASHION generates brilliant colours with
pleasant warm tones and high saturation, and completely without UV light, as well as intensive and friendly white
tones thanks to the specific blue light component, for the display of goods in perfect, colour-true light.

2.1. Complete system solution
The use of LEDs in general lighting has many advantages: LEDs are versatile in their application, highly energy efficient and virtually
maintenance-free. With the Engine SLE G6 you get a complete system solution for spot and downlights, consisting of perfectly
matched components: LED module and LED Driver.
2.2. Zhaga
Zhaga is a consortium, initiated in 2010, which takes care of the needs of LED lighting and its standardisation. It is active worldwide
and has more than 200 member companies (as of 2012).
The aim of the Zhaga consortium is to ensure interchangeability and compatibility of LED luminaires between different manufacturers.
To this end, Zhaga defines standards for the interfaces of the various lighting fixtures and holders. This includes the physical
dimensions of the lamp base, as well as the photometric, electrical and thermal behaviour of LED luminaires. These standardizing
measures help to make products comparable, a step that both the manufacturing industry and the consumers benefit from.
The Zhaga logo verifies compatibility with Zhaga standards. Only certified devices are allowed to bear this logo.
The SLE G6 modules meet the mechanical requirements of the Zhaga guidelines from book number 3. Products that meet the Zhaga
standards in physical, electrical and thermal points are listed on the website of Zhaga: www.zhagastandard.org

2.5. Compatibility between LED module and LED Driver
There are two stages involved in the check for compatibility between the LED module and the LED Driver.
2.5.1. Comparison of data sheet values with a 5-point guideline
Different values for the two devices need to be considered when comparing the data sheets. The following table shows which values
are involved and which requirements they must meet.

½ CAUTION!
LED modules SLE G6 are basic isolated against ground up to 75 V (for LES10, LES15 and LES17: 50 V) and can be mounted directly
on earthed metal parts of the luminaire.
If the max. output voltage of the LED Driver (also against earth) is above 75 V (for LES10, LES15 and LES17: 50 V), an additional
isolation between LED module and heat sink is required (for example by isolated thermal pads) or by a suitable luminaire
construction.
At voltages > 60 V an additional protection against direct touch (test finger) to the light emitting side of the module has to be
guaranteed. This is typically achieved by means of a non removable light distributor over the module.
The requirements for operating together can be checked by comparing the data sheets_
Subsequent practical tests can ensure that there are no unexpected problems during actual operation_
Determine forward current of LED module_
Check whether LED Driver can be operated with the same output
current
_
Check whether max. DC forward current of LED module is greater than
or equal to output current of LED Driver (including tolerances)
_
½ CAUTION!
The max. DC forward current can be temperature dependent!
Refer to the derating curve of the LED module data sheet.

level
_
In case there is no data available for the LED module at lowest dim
level: take the min. forward voltage minus 20 % as an
approximation

Check whether the forward voltage of the LED module is greater
than or equal to the min. output voltage of the driver

Check whether max. permissible LF current ripple of LED module is
greater than or equal to output LF current ripple of LED Driver
_
Check whether max. permissible peak current of LED module is
greater than max. output current peak of LED Driver
_
Check whether power range of LED module is completely within
output power range of LED Driver

EOS/ESD safety guidelines
The device/module contains components that are sensitive to electrostatic discharge and may only be installed in the factory and
on site if appropriate EOS/ESD protection measures have been taken. No special measures need be taken for devices/modules with
enclosed casings (contact with the pc board not possible), just normal installation practice.
Please note the requirements set out in the document EOS/ESD guidelines (Guideline_EOS_ESD.pdf) at:

3.1.1. Notes on installation
Depending on the installation situation for the LED Driver and the modules, the following requirements must be met:
Protection measures against damage
Mechanical stress
LED modules contain electronic components that are sensitive to mechanical stress. Such stress should be kept to an absolute
minimum. In particular the following mechanical stresses should be avoided as these may cause irreversible damage:
½ CAUTION!
LED module and the associated housings are crimped together by sleeves.
Trying to separate LED module and housing will destroy the LED module!
All warranty and guarantee claims are void if LED module and housing are separated or if the LED module is altered, modified or
disassembled in any form.
Sufficient distance to active conducting materials_
Sufficient strain relief when the LED Driver cover is closed_
Sufficient cooling of the modules (the max. temperature at the tc point must not be exceeded)_
Unrestricted exit of light from the modules_
The module's push-in terminals allow easy wiring. They can be released via the trigger_
Pressure_
Drilling_
Milling_
Breaking_
Sawing_
and similar mechanical processing._

Compressive stresses
The components of the LED modules (circuit boards, glob-top, lenses, electronic components etc.) are sensitive to compressive
stresses. The components must not be exposed to compressive stresses.
Chemical compatibility
LED modules can be damaged by other materials, if these materials have certain chemical properties. The cause for these damages
are different gaseous compounds, which penetrate into the encapsulant of the LED and thereby attack the encapsulant, the colour
conversion phosphor or the LED chips and can affect the electrical contacts or the substrate.
Application areas for chemical substances
The following are known areas in which chemical substances are used:
The following materials must be checked for their safety:
Putting together a "safe list" is not possible due to the complexity of the topic. The following table lists possible contaminants for LED
modules, the classes of compounds and examples of possible sources.
The list shows the most commonly used materials but does not claim to be complete.
If glass or Plexiglas shields are used make sure that pressure is not exerted on the glob-top._
Only touch the LED modules at the edges
correct (left) and incorrect (right)
_
use of protective coating in applications with high relative humidity (outdoor applications),_
encapsulation of LED modules,_
cementing of LED modules,_
sealing of luminaires._
All components and auxiliaries used in the assembly of the luminaire:_
Solvents of adhesives and coatings_
Other so-called VOC ("volatile organic compounds")_
All other additional substances present in the atmosphere:_
Outgassing of adhesives, sealants and coatings_
Cleaning agents and processing aids (e.g. cutting oils and drilling coolants)_
