A heat dissipation light ring that includes a light source board, a heat transferred layer and an insulating layer. The insulating layer is set outside of the heat transferred layer. The heat transferred layer includes heat conductive part and heat transferred part. The heat conductive part is related to the light source board with heat and set tilted compared with the heat conductive part. The heat dissipation light ring includes heat transferred wall. One end of the heat transferred wall is related to heat conductive part with heat, and the other end of the transferred wall is related to heat transferred part. The insulating layer is set outside of the heat transferred layer and heat transferred wall. The heat dissipation light ring owns the advantage of the high thermal efficiency.

A light-emitting assembly that has a light-radiating element for radiating light, an optical element for influencing the light, and a transparent insulating element, which is arranged in the path of the light, wherein the insulating element is made of a material that is more thermally stable than the material of the optical element. A lamp, in particular in the form of a spotlight, having such a light-emitting assembly is also disclosed.
