2. 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

3. cycLED – no information about material content

Take a look into LED-datasheets !!!
chemical composition
„TOP SECRET“
None of the SME‘s get these information!
LED selection by material impact? -> No Chance!

* 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

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

What have we done?

8. cycLED – design for recycling & reuse (D)

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!

9. cycLED – effects and possibilities

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)
