Welcome to the OSRAM LED workshopPresented by Paul Streeter


What is an LED?

A Light Emitting Diode (LED) is a ‘solid state’ electronic component (a diode) which produces light by ‘injection luminescence’ - a different process from other lamps and tubes.‘Injection luminescence’ is a result of the semiconductor properties of the LED die and the electrical voltage applied to it. High temperatures and high voltages are not required.


Typical LED Lifetimes

If an LED is operated at its’ stated data sheet maximum current and an ambient temperature of 25°C, these would be representative lifetime figures:

Orange 250k hours

Red 150k hoursYellow 125k hoursGreen 30k hours (will improve)Blue / White 20k hours (will improve)


LED module - range overview

LED modules without opticsBACKlightLINEARlightLINEARlight flexAvailable in:Blue, Green, Red, White, Yellow


BACKlight – LM03A

Features

The backlight module is another basic unitSupplied as a chain of 8 cable connected PCB’s 30mm x 30mm x 5mm each containing 4 LED’sPCB’s can be separated by cutting the wire linksThe PCB’s can be arranged in 3D shapes if requiredPower consumption 3.2 to 4W per complete moduleDepending on spacing between PCBs module length = 240 to 555mm


BACKlight for illuminated (channel) lettering

Fits easily into shaped lettersPitch and position variable to achieve even illumination / required luminanceRetrofitted with minimal modifications (module mounting)Even illumination will be achieved over a letter width up to twice the letter depth


LINEARlight module – LM01A

FeaturesThe LINEARlight module is a basic moduleSupplied in strips 448mm x 10mm x 5mm containing 32 LED’s = 71 LEDs / metrePCB can be broken down into sub units 56mm x 10mm with 4 LED’sPower consumption: 3.2 to 4 Watts / module = 7.1 to 8.9 Watts / metreLuminous flux typically 20lm / metre (blue) to 155lm / metre (yellow)


LED emulation of cold cathode tubes

LINEARlight and LINEARlight flex modules housed in translucent coloured plastic tubes closely emulate tube lineage

• Low voltage operation• Shock and vibration resistant• Long lifetime


Assembly methods for LINEARlight and BACKlight

Self adhesive tapeFoam backed (2mm) VHB tape from 3M recommended

Nuts, bolts and washers with spacers (M4)Use spacers with BACKlight - do not tighten directly onto a surfaceTake care not to damage the printed circuit board with metal fixings!Use synthetic washers e.g. Nylon or synthetic nuts and bolts

Printed circuit board pillarsSelf adhesive or bolted to panelModule 'snaps on' using mounting holes


Electrical connection to LINEARlight and BACKlight

LINEARlightSolder wires directly to the module contact pads

Suggested minimum cable type 7/0.2mm (0.22mm2 - up to 3 modules) or 16/0.2mm equipment wire (0.5mm2 - up to 8 modules)

Use the purpose made connector system from BJB

BACKlightUse a connector system to connect to the flying leads from the modulesDo not solder directly to the circuit board (unless new protective coating is applied afterwards)Do not desolder connection wires from the circuit board (unless new protective coating is applied afterwards)


LINEARlight flex – LM10A & LM11A

FeaturesFlexible version of LINEARlightVertical or side emitting versionsSupplied on rolls 8.4m (vertical) and 4.2m (side) longSelf adhesive backing (3M VHB)Minimum bend radius 20mmMay be bent at 90º (between components) once only to fit into cornersCan be cut with scissors!


Assembly methods for LINEARlight flex

The module is supplied with a self adhesive backingSuitable for surfaces with a similar expansion rate to the module e.g. the majority of metals and some syntheticsThe self adhesive backing can be changed to suit other materials

Electrical connectionSolder wires directly to the module contact pads

Suggested minimum cable type 7/0.2mm (0.22mm2 - up to 3.9m module length) or 16/0.2mm equipment wire (0.5mm2 - up to 8.4m module length)


Dedicated control gear

OPTOTRONIC Mouse10V 12 Watt and 24V 20 WattSuitable for driving up to 1.3m of LINEARlight

ECG OPTOTRONIC for small applicationsIdeal for driving single modules10 or 24V 6 Watt

ECG OPTOTRONIC for larger applications

50 & 75 Watt 10 Volt and 24 Volt

Short circuit, overload and overheat proof

Remote mounting – up to 10 metres!

Can drive a complete reel of LINEARlight flex (8.4m) or LINEARlight colormix flex (4.2m)


LINEARlight Colormix module

Colour 'premix' system offers following benefits:

No need to diffuse or reflect light from a surface - LED's can be viewed directlyDiffusers and illuminated surfaces can be placed closer


LINEARlight Colormix module – LM01M-RGB

LM01M-RGB module450 x 12 x 3.5mm - contains 30 LED's (67 LEDs / metre)Divisible into 150mm sections17 Watts per metre maximum power consumption 160 lumens per metre luminous output (all LED's at maximum brightness)24 Volt operationOnly four connections (red, green, blue and common)Simple interface to dimmers / controllers using OSRAM control gear'One stop' colour mix solution


LINEARlight Colormix flex – LM10M-RGB

LM10M-RGB colormix flex4200 x 12 x 3.5mm - contains 280 LED's (67 LEDs / metre)

Divisible into 150mm sections

Supplied on rolls with self adhesive backing (3M VHB)

Minimum bend radius 20mm

May be bent at 90º (between components) once only to fit into corners


LINEARlight Colormix


Colormix control

Three channel (red, green, blue) control unit forcolour mixing applications

Can control up to 2.8m of LINEARlight colormix

Three independent dimming circuits each with acontrol inputs
