Description
本發明涉及一種燈泡，尤其涉及一種燈泡及其燈殼。 The invention relates to a light bulb, in particular to a light bulb and a lamp housing thereof.
通常，燈泡外殼均為金屬所製成，主要包括：銅、鋁或其合金等高導熱係數的材料。其金屬外殼幾乎都是用鑄模成型的方式製作，為了達到良好的散熱效果，往往增加外殼的表面積，製作出許多具有凹凸表面的散熱鰭片。但是使用這樣的設計，空氣只流過散熱鰭片一次之後就不會再加以迴圈而導致散熱效果不佳。 Usually, the bulb outer casing is made of metal, and mainly includes materials with high thermal conductivity such as copper, aluminum or alloys thereof. The metal casing is almost always made by molding. In order to achieve good heat dissipation, the surface area of the casing is often increased, and a plurality of fins having concave and convex surfaces are produced. However, with such a design, air only flows through the fins once and then does not loop again, resulting in poor heat dissipation.
有鑒於此，有必要提供一種散熱效果較好的燈泡及其燈殼。 In view of this, it is necessary to provide a bulb having a better heat dissipation effect and a lamp housing thereof.
一種燈殼包括相對的第一端面和第二端面，其上開有貫通的散熱通道。所述散熱通道為四周封閉的通孔且沿第一端面到第二端面方向延伸，該通孔能夠加速空氣的對流和迴圈。 A lamp housing includes opposing first end faces and second end faces with a heat dissipation passage therethrough. The heat dissipation channel is a through hole closed around and extends along the first end surface to the second end surface, and the through hole can accelerate the convection and loop of the air.

The lamp housing is provided with a through heat dissipation channel. The heat dissipation channel is a through hole closed around and extends along the first end surface to the second end surface, and the through hole can accelerate the convection and loop of the air.
