1. An illuminating device comprising:
- a light engine;
a housing;
a driver contained in the housing;
a heat dissipation device disposed in the housing, wherein the heat dissipation device comprises;
a substrate for supporting the light engine; and
an insert ring in thermal-conductive contact with the substrate;
a holder having a central aperture configured to receive the light engine, wherein the holder and the housing together hold the heat dissipation device between the holder and the housing;
wherein a plurality of mounting poles are disposed in the housing and distributed in a circumferential direction of the housing and extend along an axial direction of the housing;
wherein the holder comprises a plurality of first mounting holes;
wherein the substrate comprises a plurality of second mounting holes disposed in a circumferential direction of the substrate;
wherein the plurality of mounting poles comprises a plurality of third mounting holes; and
wherein, in an assembled state, the mounting poles pass sequentially through the insert ring and the second mounting holes of the substrate such that at least one fastening structure passes through the first mounting holes and the second mounting holes to mount the holder to the housing.
