Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a flat light bulb. Background Technology

[0002] In the field of lighting fixtures, in order to meet functional needs and take into account a certain degree of decoration, bulbs are usually made in the form of spherical bulbs, cylindrical bulbs, spiral bulbs, candle bulbs, tubular bulbs, etc. These bulbs are usually designed to provide basic lighting and are relatively conservative in design. Utility Model Content

[0003] To overcome the aforementioned deficiencies in the prior art, this utility model provides a flat light bulb, comprising: a lampshade including a lampshade body and a lampshade connecting portion located at the bottom of the lampshade body; a light-emitting element; a driving unit electrically connected to the light-emitting element; and a lamp holder connected to the lampshade connecting portion for electrically connecting the flat light bulb to a lamp base. The light-emitting element is disposed within the internal space of the lampshade and / or the lamp holder, and at least a portion of the lampshade body has a flat shape. Accordingly, the flat light bulb of this utility model has a unique design for decorative purposes and can be adapted to various shapes, and the flat light bulb can be adapted to various lamp bases by the user as needed.

[0004] Furthermore, at least a portion of the lampshade body is circular, elliptical, or polygonal; and / or the lampshade is transparent or translucent. Accordingly, the flat bulb of this invention can be designed in various shapes or appearances.

[0005] Furthermore, the light-emitting element is a filament. This allows for cost reduction and full adaptation to the shape or appearance of a flat bulb.

[0006] Furthermore, the lampshade includes a first lampshade portion and a second lampshade portion, which are joined together by adhesive or ultrasonic welding. This makes it easier to manufacture the lampshade.

[0007] Furthermore, the first lampshade portion and / or the second lampshade portion are formed with grooves, and the light-emitting element is disposed within the grooves. This allows the light-emitting element to be securely and stably arranged within the lampshade.

[0008] Furthermore, the light-emitting element is disposed between the first lampshade portion and the second lampshade portion. This allows for more uniform light emission from both sides of the flat bulb.

[0009] Furthermore, the light-emitting element is disposed around the main body of the lampshade. This makes the flat bulb more aesthetically pleasing when illuminated.

[0010] Furthermore, the light-emitting element is disposed within the main body of the lampshade. This makes the flat bulb more aesthetically pleasing when illuminated.

[0011] Furthermore, the lampshade body is composed of a portion of the first lampshade portion and at least a portion of the second lampshade portion, and the lampshade connecting portion is composed of the remaining portion of the first lampshade portion or the remaining portion of the first lampshade portion and the remaining portion of the second lampshade portion. Accordingly, the lampshade can be manufactured more easily.

[0012] Furthermore, the driving unit is disposed within the lamp holder. Further, a conical or cylindrical space is formed inside the lamp holder, and the driving unit is disposed within this conical or cylindrical space. This allows for better concealment of the driving unit, resulting in a more aesthetically pleasing appearance for the flat bulb.

[0013] Furthermore, the driving unit is located at the junction between the lamp holder and the lamp cover. This allows for a balance between the aesthetics of the flat bulb and the ease of connecting the driving unit to the light-emitting element.

[0014] Furthermore, the driving unit is disposed within the lampshade connecting portion. Furthermore, a conical or cylindrical space is formed inside the lampshade connecting portion, and the driving unit is disposed within this conical or cylindrical space.
