ABSTRACT:
A thermal dispersing structure for LED or SMD LED lights is to mount a lamp base on a light head. The lamp base is funnel-shaped and has an interior annular cutout near its top edge. A substrate engages the annular cutout to carry one or multiple LED or SMD LED units at a center or other proper locations. Moreover, a rim is formed on the substrate around the LED or SMD LED units. The substrate has multiple holes defined corresponding to thermal conducting bases under the LED or SMD LED units and defined slightly larger or smaller than the LED thermal conducting base. Additionally, a thermal dispersing body is secured under the substrate and has multiple posts corresponding to the holes of the thermal conducting bases. Each post penetrates the substrate to snugly engage the thermal conducting base so that thermal dispersing efficiency is improved.
