cycLED main issue

1

Reduce REM &

TM footprint of LED-product

and recover REM &

TM

Take a look into LED-datasheets !!!

Electrical parameters

Optical parameters

Dimensions & footprint

Processing & handling parameters

Order information

REM rear earth metals TM target metals

cycLED no information about material content

chemical composition

TOP SECRET

None of the SMEs get these information!

LED selection by material impact? -> No Chance!

cycLED change focus

expand lifetime

reduce energy

consump-tion

reduce material impact

design for

recycling and

reuse

What can SMEs do?

(A) (B) (C) (D)

cycLED expand lifetime/reduce energy consumption (A & B)

4

Junction temperature

Life time Efficiency Energy consumption

Junction temperature LED current LED efficiency LED driver (efficiency)* ()

* Current LED-drivers should reach 100k+x hours lifetime (datasheet information), but these are often the reason for broken LED-products!

Implemented features Active temperature control with current regulation Smart light control adopt light-output to the needs Reduced standby power consumption Optimized electronic schematic and parts

Benefits & effects Customer (longer lifetime) Customer (costs, feeling, environment) Customer (costs, environment) Customer (costs, lifetime)

both with approx. the same power consumption ->

Comparison of aluminium (heat sink) Benchmark cycLED Demonstrator Raw material 2260g 320g (for 11 pcs)

Finished module 1621g 292g ( for 6 pcs)

Losses (per luminaire) 639g (28.3%) 28g (4.8%)

Assembly time (LED to heatsink) 30 min 1 min (each module)

Disassembly time (LED from heatsink) Nonexecutable 30s (each module)

Reuse / refurbishing parts Only 2 heat sinks LED Block - waste Approx. all

cycLED design for recycling & reuse (D)

What have we done?

cycLED design for recycling & reuse (D)

7

Main facts:

1. No one knows products better than the manufacturer!

2. Knowledge of assembling is knowledge for disassembling!

3. Knowledge of disassembling gives possibility to improve

Pre-Selection and Pre-Sorting.

4. Pre-Selection and Pre-Sorting improves quality and quantity of

REM- and TM-output in the recycling process!

cycLED effects and possibilities

8

Effects and possibilities:

Cost reduction for resources (raw material)

Possibility for less expensive products

Reduce energy consumption

Reduce resource consumption (exploration, mining)

Protect environment (global warming and pollution)
