The invention relates to a lighting device (300) including a light emitting unit (303), a driving unit (304) for driving the light emitting unit and a heat dissipating structure. The heat dissipating structure includes an inner housing (302) for accommodating the driving unit therein; and an outer housing (301) configured to encircle the inner housing, thereby forming a space (309) between the inner housing and the outer housing. A plurality of openings (30111) are arranged in the side wall (3011) of the outer housing so as to allow air to flow into the space and moves over the surfaces of the inner housing and the outer housing. One of the main advantages of this invention is that the heat dissipating structure is concise in structure and can be manufactured at low cost while the thermal performance can remain almost the same or is even better. |
