Thermal foldback Application Example Back side: LED driver Connecting back side of LED driver to fixture heatsink will protect LED fixture against overheating thus extending LED life time and provide safe fixture operation even for inappropriate installations. Thermal foldback is temperature of the module is set to ~80°C Front side: LED module thermal connection can be done by appropriate thermo conductive both side tape or glue. Line regulation LED count = 12x Ta=24°C, Rh=61% thermal connection heatsink Futuro Lighting

Analog Dimming example (local) Appropriate for local dimming (Potentiomter close to Driver) Dimming level (%) * soft start capacitor Potentiometer selection: LIN - linear for linear dimming change LOG - logarithmic change, more appropriate for human eye response Literature: http://www.ti.com/lit/ds/symlink/lm385b-2.5.pdf Futuro Lighting

Analog Dimming example (remote) Appropriate for remote dimming (1-10V dimmer) Dimming level (%) M1 soft start capacitor Signal selection: LIN - linear for linear dimming change LOG - logarithmic change, more appropriate for human eye response Futuro Lighting
