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.
