Abstract
Lighting devices are provided. A lighting device includes a first substrate, a second substrate, a light source and a thermoelectric cooling chip set disposed between the first and second substrates. The first substrate includes a core, a first circuit layer, and a second circuit layer, wherein the first and second circuit layers are disposed on opposite sides of the core. The second substrate comprises a third circuit layer. The light source is disposed on the first substrate and electrically connected to the first circuit layer. The thermoelectric cooling chip set is electrically connected to the second and third circuit layers, to dissipate heat from the light source.
