DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be explained below in conjunction with the accompanying drawings1to8.

The present disclosure provides a lamp panel plugged type LED lamp bulb, including a lamp holder1and a lamp bulb shell2fixedly connected to the lamp holder1, and further including an insulation fixed seat3and a lamp panel type light source assembly4for vertical mounting; the insulation fixed seat3is arranged at an opening portion of the lamp bulb shell2; the insulation fixed seat3at least includes an assembling portion31that is closely fitted and assembled with the opening portion of the lamp bulb shell2and a plugging portion32configured to mount the lamp panel type light source assembly4; the plugging portion32is provided with a plugging slot321; at least two conductive contacts a322are provided on an inner side of the plugging slot321; one conductive contact a322is electrically connected to a positive electrode of the lamp holder1; the other conductive contact a322is electrically connected to a negative electrode of the lamp holder1; the lamp panel type light source assembly4at least includes a base plate41and LEDs42which are arranged along at least two opposite surfaces of the base plate41and are electrically connected; a circuit is deployed on the base plate41; the LEDs42are electrically connected to the circuit, and outer surfaces of the LEDs42are coated with a fluorescent glue layer43; the base plate41is provided with two conductive contacts b411; one end of the base plate41is plugged into the plugging slot321to make the conductive contacts b411communicate with the conductive contacts a322; and the other end of the base plate41extends into the lamp bulb shell2.

The present disclosure improves the wick structure of the existing lamp bulb from the existing welded type wick structure into a lamp panel plugged type wick structure. The insulation fixed seat3is electrically connected to a lamp panel through the conductive contacts a322and the conductive contacts b411, so that two ends of a light bar can be electrically connected to a metal wire without a welding process. This significantly simplifies the forming process of the lamp bulb, shortens the overall forming time of the lamp bulb, and greatly reduces the forming cost of the lamp bulb. Secondly, after a lamp panel is integrated, the lamp panel is directly inserted into the plugging slot321to complete an entire assembling process of a wick, and the wick assembling efficiency is greatly improved.

In this technical solution, one conductive contact a322is electrically connected to the positive electrode of the lamp holder1through a first conductive wire5, and the other conductive contact a322is electrically connected to the negative electrode of the lamp holder1through a second conductive wire6; the insulation fixed seat3is provided with at least two wire holes33; one end of the first conductive wire5and one end of the second conductive wire6respectively extend at least into the plugging slot321through the wire holes33.

Based on the above solution, as an embodiment, as shown inFIG.3, the first conductive wire5and the second conductive wire6both extend out of the plugging slot321and form a bent portion51; the bent portion51reversely hooks a side wall of the plugging slot321to position and mount the conductive wires; and at this time, the conductive contacts a322are a portion of the first conductive wire5and a portion of the second conductive wire6. Arc-shaped bends formed by the bending of the conductive wires simultaneously endow the conductive contacts a322with elasticity, so that the conductive contacts a322and the conductive contacts b411can maintain a tight fit all the times and have good conductive contact.

To further conceal and better fix the conductive wires an accommodating slot327configured to accommodate the bent portion51is provided on a side wall of the plugging slot321. The accommodating slot327is further conductive to making the structure more compact and avoiding end portions of the conductive wires from extending out.

As another embodiment, as shown inFIG.4, the conductive contacts a322are conductive elastic sheets323embedded in the plugging slot321; and the first conductive wire5and the second conductive wire6are respectively electrically connected to the conductive elastic sheets323. The conductive elastic sheets323are elastic, so that a good electrical contact can also be made between the conductive contacts a322and the conductive contacts b411.

As a preference, a partition plate324is further arranged in the plugging slot321. The partition plate separates the two conductive contacts a322, the first conductive wire5, and the second conductive wire6to avoid a short circuit in the lamp bulb caused by mistouch of two electrodes. Similarly, the base plate41is provided with a socket412that cooperates with the partition plate324. Two conductive contacts b411are respectively located on two sides of a gap, which can prevent a short circuit in the lamp bulb too. Secondly, the lamp panel is plugged into the partition plate324, which can form a fixed support for the base plate41and achieve stable mounting of the lamp panel.

As a preference, the assembling portion31is formed by a flexible glue material, so that the assembling portion31can be in tight fit with the opening portion of the lamp bulb shell2to seal the opening portion of the lamp bulb shell2, and the lamp bulb has good waterproof performance. The plugging portion32is formed by a hard colloid material. The plugging portion32formed by the hard material can ensure that the conductive contacts do not shift and ensure stable contact between the conductive contacts a322and the conductive contacts b411. The insulation fixed seat3formed by the two materials can provide good waterproof performance for the lamp bulb, and ensure good electrical contact of the lamp bulb.

As an embodiment, as shown inFIG.5, the plugging slot321is provided with a bottom plate10for blocking, and the wire holes33are provided on the bottom plate10for blocking. When the base plate41is mounted in the plugging slot321, the bottom plate10for blocking can limit the base plate to avoid excessive plugging. An assembling slot311configured to plug and assemble the plugging portion32is provided at a top end of the assembling portion31. At this time, the assembling portion31wraps around the plugging portion32.

As another embodiment, as shown inFIG.6, a top end of the assembling portion31upwards extends to form a protruding portion312; and a mounting slot325configured to accommodate the protruding portion312is provided at a bottom end of the plugging portion32. At this time, the plugging portion32wraps around the assembling portion31. In this embodiment, the plugging slot321is also provided with a bottom plate10for blocking, and the wire holes33are provided on the bottom plate10for blocking. When the base plate41is mounted in the plugging slot321, the bottom plate10for blocking can limit the base plate to avoid excessive plugging.

As a preference, the protruding portion312is at least provided with two positioning holes313; two positioning columns326are at least arranged in the mounting slot325; and the positioning columns326are plugged into the positioning holes313. The assembling portion31and the plugging portion32are positioned and mounted through the positioning columns326and the positioning holes313. This structure is added to assist in improving the production and assembling efficiency of the insulation fixed seat3.

In this technical solution, the assembling portion31and the plugging portion32can be separately formed and then assembled into a whole, or they can be integrally injection-molded in two stages.

In this technical solution, the base plate41is formed by a polyvinyl chloride (PVC) material. Compared with a ceramic base plate41, the PVC base plate41has better toughness, is less prone to bending and breakage, and has a longer service life. The base plate41is a T-shaped thin plate, including an insertion portion413and a light source portion414. A width of the insertion portion413is greater than that of the light source portion414, so that the base plate41can form a stable support for the light source portion414after being plugged. The conductive contacts b411are long-strip blocks and are arranged on a surface of the insertion portion413. Contact areas of the long-strip block-shaped conductive contacts b411are larger, and the conductive contacts a322and the conductive contacts b411can be better conducted.

The present disclosure further includes at least one resistor7. The resistor7is arranged on a conductive wire or is integrated on the base plate41. When integrated on the base plate41, the resistor has a better cost advantage and a better assembling efficiency advantage.

A person of ordinary skill in the art can make changes to specific implementations and the application scope according to the idea of the present disclosure. The content of this specification should not be understood as a limitation on the present disclosure.
