Abstract
An LED illuminating device includes a hollow base including a first end and a second end, an LED substrate, a connector, and a driving circuit module accommodated in the base. A plurality of vents are defined in a circumferential wall of the hollow base; a space is formed between a circumferential wall of the driving circuit module and the inner surface of the circumferential wall of the hollow base. The space can communicate with the plurality of vents and serve as a hot air channel, to promote heat exchange between hot air in the base and cool air outside the base.

An LED illuminating device, comprising:
- a hollow base comprising a first end and a second end opposite to the first end, the hollow base comprising a circumferential wall, and a plurality of rows of vents defined in the circumferential wall of the hollow base, each of the rows of the vents being arranged along a direction from the first end to the second end, each of the rows of the vents including an intake vent adjacent to the first end and an outlet vent adjacent to the second end;
- an LED substrate mounted on the first end of the hollow base and comprising a plurality of LEDs;
- a driving circuit module accommodated in the hollow base and electrically connecting with the LEDs;
- and
- a space formed between a circumferential wall of the driving circuit module and an inner surface of the circumferential wall of the hollow base, the space being communicated with the vents;
- wherein the intake vents are configured for introducing cold air to the space and the outlet vents are configured for allowing hot air in the space to exit therethrough.
