Abstract
The present invention relates to a light device with a heat-dissipating apparatus, including a bulb assembly and a hood positioned outside the bulb assembly to generate cyclone passing by the outer surface of the bulb assembly. The hood of the present invention further includes a plurality of blades and a neck. As the airflow passes through the hood, the blades and the neck divert the airflow into cyclone passing by the outer surface of the bulb assembly to facilitate heat dissipation. The present invention may further include a first heat-isolating board and a second heat-isolating board to isolate heat radiation.
Claims9
A light device, comprising:
- a bulb assembly having an outer surface;
- and
- a hood including a neck portion and a noise elimination portion located adjacent to said neck portion for eliminating noise caused by a flow of air through said neck portion, said hood being positioned outside said bulb assembly for generating cyclone passing by at least part of said outer surface of said bulb assembly,
- wherein the cross sectional area of said noise elimination portion is larger than the cross-sectional area of said neck portion.
A light device, comprising:
- a bulb assembly including an outer surface and a light emitting surface;
- a hood positioned outside said bulb assembly for generating cyclone passing by at least part of said outer surface of said bulb assembly;
- a set of connection frames for connecting said bulb assembly to said hood, said set of connection frames including a front frame positioned outside said light emitting surface of said bulb assembly and at least one holding frame positioned outside said outer surface of said bulb assembly,
- wherein said hood includes at least one accommodation portion connected to said front frame and said at least one holding frame to thereby connect said bulb assembly to said hood.
