Equipped with circular hole 32.
Light emitting devices 1 is placed in the blind hole 21 of cooling base 2 in the present embodiment, and the pin 11 of light emitting devices 1
It is pierced by, exposes outside cooling base 2 from the through-hole 22 of 21 bottom of blind hole；Heat dissipation tabletting 3 is matched through the screw across circular hole 32 thereon
It closes the screw hole on cooling base 2 heat dissipation tabletting 3 is fixed on cooling base 2, light emitting devices 1 is fixed on by heat dissipation tabletting 3
On cooling base 2.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, variation, addition or the replacement made should all belong to this reality
With novel protection domain.
