Description

Technical Field

[0001] The utility model belongs to the technical field of light bulbs and relates to a light bulb. Background Art

[0002] A light bulb is a lighting source that emits light and heat through electrical energy. Light bulbs are made based on the principle of thermal effect of electric current. When the light bulb is connected to the rated voltage, the current passes through the filament and is heated to an incandescent state (above 2000C), thus generating heat and light, thereby converting electrical energy into internal energy and light energy during operation. With the development of society, the use of light bulbs has also undergone different changes. Initially, it may have been to provide convenience for production and life, but with the progress of society, there have also been obvious changes in the use of light bulbs, and functional lamps for different purposes such as "automobiles, beautification of the environment, decoration", etc. have begun to appear.

[0003] An existing decorative light bulb is installed with a light board, and the shape of the light board varies to achieve the purpose of decoration. However, the light board in the light bulb is currently fixed directly on the metal frame by welding. Since the metal frame is light in structure and the light board has a certain weight, the metal frame cannot provide good support for the light board. If the light bulb shakes, it is easy to cause the light board to move. When the light board moves, it will distort the metal frame, causing it to deform, making the image of the light bulb look ugly and lowered. In addition, the shaking light board will also bump against the inner wall of the light bulb, causing wear on the inner wall of the light bulb. Utility Model Content
