Abstract
A heat dissipating apparatus for lighting utility includes a casing, a light-focusing unit, a light-reflecting unit, a heat-dissipating unit, a light generator, a wind generator, a cover and a circuit board. The heat-dissipating unit absorbs a heat generated from the light generator, the wind generator circulates air outside the casing and inside the casing, whereby the heat absorbed by the heat-dissipating unit is dissipated outside the casing.
