Abstract
A street lamp system includes a hollow lamp post, an illumination device, a wind turbine, a connecting shaft and a number of fan leaves. The lamp post has an air flowing channel defined therein. The illumination device includes a solid-state light source and a heat dissipation device thermally coupled to the solid-state light source, and is coupled on the lamp post with the heat dissipation device disposed in the air flowing channel. The wind turbine is mechanically coupled to the lamp post to be driven by wind energy to rotate, thereby directing flowing of the air in the channel from the air inlet to the air outlet.
