Abstract
Lamp module cooling system 10 contains vehicle solid-state light source 12 coupled to an extruded first heat sink 2 and an extruded second heat sink 20 in thermal communication with one another and with fluid flow directed from fan air outlet 42 of fan 40 over respective heat dissipation first and second ribs 8, 28 to direct warmed air through existing apertures 115 in headlamp bezel 110 aligned with headlamp optics 130 to defog or de-ice headlamp cover 100. Housing cover 30 and cover 32 define air flow path 50, 52, 54 improving warm air guidance and efficient spatial packaging of lightweight lamp module cooling system 10.
