Abstract

[Use of the article]; This creation is about a new style design of a "LED bulb", especially an LED bulb used to provide lighting. ; [Features of the creation]; As shown in the attached figure, the LED bulb of this creation includes from bottom to top: a lamp holder with external threads, a bulb body connected to the top of the lamp holder, a heat dissipation cover arranged around the middle of the bulb body and extending upward and outward, and a light-transmitting lampshade covering the bulb body and correspondingly combined with the heat dissipation cover; the light-transmitting lampshade is an arc convex surface. The heat dissipation cover is in the shape of an arc, and near the junction with the heat dissipation cover, there are multiple longitudinal elliptical perforations, and the periphery of each perforation is inclined outwards through the guide angle; the heat dissipation cover is in the shape of an arc in the direction away from the light-transmitting lampshade, and there are multiple longitudinal narrow heat dissipation holes on the upper ring, and the periphery of these heat dissipation holes is inclined outwards through the guide angle and is aligned with the perforations of the light-transmitting lampshade. ; In summary, the shape of this creation is simple and fresh, and the arc lines create a smooth visual effect, which can be called an innovative design with both practicality and aesthetics.
