LED bulb

Abstract

The invention discloses an LED bulb, particularly the LED bulb with a stable structure and a favorable heat-dissipation property. The bulb comprises a bottom casing, a base, a bulb casing, a lighting unit and a bulb shade, wherein the bottom casing is connected with the base through threads, the bulb casing is in a circular truncated cone structure, and the bulb casing is in an integrated structure. A whole piece of metallic materials is adopted to process the bulb casing, the structure of the bulb casing is arranged in a integration manner, the structure ensures the intensity and the stability of the bulb casing, and the materials are more uniform and unified, so that the heat conduction and the heat dissipation are more uniform and quicker, the situation that the local temperature is too high is avoided, the service life of the whole bulb can be effectively prolonged, the reliability of the whole bulb can be effectively improved, the steps of the production technology are simplified, waste and leftover materials are reduced, the utilization rate of materials is improved, and the bulb is more environmental-friendly.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED bulb with stable structure and good heat dissipation performance. Background technique [0002] LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. Heat dissipation is a major factor affecting the lighting intensity of LED lamps. LED lamps are 80% more energy efficient than traditional incandescent lamps. However, its LED components and driver circuit have a large amount of heat dissipation. If the heat is not properly discharged, the luminosity and life of the LED lamp will drop sharply; the light-emitting unit and lamp housing of the LED bulb in the prior art are generally divided into several The components are then assembled, which leads to poor heat conduction speed at the joints of various components, uneven material, uneven heat dissipation, insufficient strength and structure of the lamp housing, etc. The contact surface ...

[0002] LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. Heat dissipation is a major factor affecting the lighting intensity of LED lamps. LED lamps are 80% more energy efficient than traditional incandescent lamps. However, its LED components and driver circuit have a large amount of heat dissipation. If the heat is not properly discharged, the luminosity and life of the LED lamp will drop sharply; the light-emitting unit and lamp housing of the LED bulb in the prior art are generally divided into several The components are then assembled, which leads to poor heat conduction speed at the joints of various components, uneven material, uneven heat dissipation, insufficient strength and structure of the lamp housing, etc. The contact surface space between the light-emitting unit and the lamp housing is too small. It is good for heat dissipation; moreover, a large amount of corner waste will be generated during the production process, which is not conducive to the utilization of materials
