Solid state display light
First Claim
1. A LED lamp comprising a gear column, a lamp cap which is connected to an end of the gear column and a substrate which is connected to the other end of the gear column, wherein the substrate includes at least one LED and the gear column comprises heat-dissipating means interconnecting the substrate and the lamp cap, the lamp further comprising cooling means in the gear column, which are used to generate an air flow in the lamp.

Abstract
An LED lamp has a gear column which is connected between a cap and a substrate. The substrate is provided with a regular polyhedron of at least four planes, the planes having at least one LED which has a luminous flux of at least 5 lm. The gear column also has a heat-dissipater which interconnect the substrate and the lamp cap.
