WHY CERAMICS
??
7
• 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
• Ceramic based components
on
ceramic circuits ;Lesser ∆ in ThermalExpansion

PLACEMENT EASY ? NOT !
13
• 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

OR….COMBINE REGULAR LED’S &
CSP!

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 !
