Patent ID: 8057071

Claim:
An end-side heat extraction LED lamp assembly comprising: a lamp housing having an electrical connection adapter at one end thereof and a light projection end at an opposite end thereof and an inner housing space; a cooling module positioned within said inner housing space of said lamp housing, said cooling module having a cooling fan and a cooling base, said cooling fan positioned within said cooling base, said cooling fan having an airflow guidance frame, said cooling base having a pedestal and an LED joint surface and multiple fins, said multiple fins having edges protruding outwardly from edges of said pedestal of said cooling base; an LED lighting set positioned on said LED joint surface; a circular frame extending from said airflow guidance frame of said cooling fan to said light projection end of said lamp housing; and at least one end-side heat extraction airflow guidance passage defined by a through space at the edges of said multiple fins and edges of said pedestal, an inner side of the end-side heat extraction airflow guidance passage corresponding to said cooling fan, an outer side of the end-side heat extraction airflow guidance passage corresponding to an end side of said light projection end of said lamp housing, the end-side heat extraction airflow guidance passage passing air from said cooling fan directly outwardly in a direction toward said light projection end, said LED joint surface having a refraction mirror, said refraction mirror extending so as to form a barrier edge blocking an outer end of said end-side heat extraction airflow guidance passage, said barrier edge having an airflow passing hole thereon aligned with said end-side heat extraction airflow guidance passage.
