Abstract: A low-cost integrated reflector and heat spreader for high-density high power solid-state (e.g., LED) lighting arrays includes a base structure onto which is applied a sacrificial material. A relatively thick thermal spray coating is applied over the base structure and sacrificial material. The sacrificial material is removed. A channel(s) is thereby provided within the thermal spray coating layer and in physical contact with the base structure. The channel may be filled with a cooling fluid. A pulsating heat pipe heat spreader may thereby be provided. A reflective material may be provided either over another surface of the base structure or alternatively over the thermal spray coating layer to provide a surface for reflecting and directing light emitted from a solid state light source that may be secured to the integrated reflector and heat spreader.
