WHY CERAMICS

??

• Working temperature from below 0°C up to >400°C

• Excellent thermal

conductivity

• High dielectric strength

• Printable resistors

• Also trimmable

• Lifetime• High power LED’s / resistors

• CSP LED’s are quite fragile

• CSP LED’s are difficult to place on pick &

place

• CSP LED’s are very difficult to rework

SUMMARY, WHY CSP YOU

ASK?

15

• Due to the small dimensions good options for:

• ”Tunable white” / “Dim 2 warm”

• Light distribution and also thermal distribution

• Space

• More possibilities for driver integration

• Spotlights

• “Under driven” → low current (more led’s) but more

lumen/watt

• More equal distributed, less glare

• Combinations with other type of led’s (5630(3030/2830) / 3535 /

etc.)

• COB replacements (lower costs)

• COB customization

SOLUTION WITH LM101A(150⁰)More LED’s, better Lm/W and a more uniformlight surface!

OR….COMBINE REGULAR LED’S &

CSP!

24

Why not add colors ?

So far, we’ve been only talking about white LED’s.

Horticulture business is demanding a small footprint , variable wavelenghtsand high performance.

White LED’s are then not the answer!

Heat is mostly an issue !
