Light-emitting heat-dissipating device
A light-emitting heat-dissipating device includes a base, a light-emitting annular set, a fan and a cover. The base has an annular frame and a pivotal connection portion. The light-emitting annular set is annularly disposed at the annular frame of the base. The fan is pivotally disposed at a pivotal connection portion of the base. The cover is disposed on the annular frame of the base. The light-emitting annular set is annularly disposed between the cover and the base such that the light-emitting annular ring is not subjected to any external force or weight and thereby not predisposed to damage. The light-emitting annular set enables a halo with uniformly-distributed brightness to be formed above the light-emitting heat-dissipating device.
1. A light-emitting heat-dissipating device, comprising:
a base having an annular frame and a pivotal connection portion;
a light-emitting annular set annularly disposed at the annular frame of the base;
a fan pivotally disposed at the pivotal connection portion of the base; and
a cover disposed on the annular frame of the base, wherein the light-emitting annular set is disposed between the cover and the base;
wherein the light-emitting annular set comprises a light guiding portion which is slender, annular and annularly disposed on the annular frame, and at least a light-emitting unit disposed on the light guiding portion.
2. The light-emitting heat-dissipating device of claim 1 , wherein the light-emitting units are light-emitting diodes.
3. The light-emitting heat-dissipating device of claim 1 , wherein the light guiding portion comprises at least a light-emitting unit receiving chamber.
4. The light-emitting heat-dissipating device of claim 3 , wherein the light-emitting units are light-emitting diodes.
5. The light-emitting heat-dissipating device of claim 1 , further comprising aside-opening hole disposed between the cover and the annular frame of the base.
6. The light-emitting heat-dissipating device of claim 1 , further comprising aside-opening hole disposed between the cover and the annular frame of the base.
7. The light-emitting heat-dissipating device of claim 2 , further comprising aside-opening hole disposed between the cover and the annular frame of the base.
8. The light-emitting heat-dissipating device of claim 3 , further comprising aside-opening hole disposed between the cover and the annular frame of the base.
9. The light-emitting heat-dissipating device of claim 4 , further comprising aside-opening hole disposed between the cover and the annular frame of the base.
