Description

Technical Field

[0001] The utility model relates to the field of lighting appliances, in particular to a light bulb. Background Art

[0002] Existing light bulbs are generally composed of a filament, a lampshade, a lamp holder, a conductive aluminum cup and a plastic shell. During the production process, the lamp holder and the plastic shell are generally combined into a structural member, and then the lamp holder and the conductive aluminum cup are connected so that the lamp holder can transmit electrical signals to the conductive aluminum cup, and the plastic shell plays a role in preventing electric shock and connecting the lamp holder and the conductive aluminum cup. The above production method is relatively cumbersome, with low production efficiency, and has high requirements for the tightness of the connection between the lamp holder and the conductive aluminum cup. When the lamp holder and the conductive aluminum cup become loose, it will affect the conduction of the circuit. Utility Model Content

[0006] The conductive cup and the lamp holder are integrally formed, and the outer diameter of the conductive cup is greater than the outer diameter of the lamp holder.

[0007] Furthermore, an inner plastic shell is embedded in the conductive cup.

[0008] Further, the conductive cup includes a main body and a transition connection portion;

[0009] The lamp holder is transitionally connected to the main body via a transition connection portion, and an outer diameter of the transition connection portion gradually increases in a direction away from the lamp holder.

[0010] Furthermore, the outer diameter of the main body is greater than the outer diameter of an end of the transition connection portion close to the lamp holder.

[0011] Furthermore, the main body is cylindrical.

[0012] Furthermore, the conductive cup outer shell is provided with a silicone sleeve.

[0013] Furthermore, it also includes a lamp housing and a light source assembly; one end of the light source assembly is embedded in the conductive cup and electrically connected to the conductive cup, and the lamp housing is covered outside the other end of the light source assembly and connected to the conductive cup.

[0014] Furthermore, the light source assembly includes a light emitting assembly and a driver; the light emitting assembly is electrically connected to the driver, the driver is embedded in the conductive cup, and the lamp housing is covered outside the light emitting assembly.

[0015] Furthermore, the light-emitting component includes a filament and a stem; the filament is spirally arranged around the stem and is electrically connected to the stem, and the stem is electrically connected to the driver.

[0016] Furthermore, the conductive cup is made of aluminum.

[0017] The beneficial effects of the utility model are that the conductive cup and the lamp holder are integrally formed to simplify the production process, and the conductive cup and the lamp holder are always kept in close connection, so that the circuit remains conductive in real time. Compared with existing light bulbs, the conductive cup and the lamp holder can be connected without providing an outer plastic shell, which simplifies the production process and reduces production costs.
