In order to achieve the abovementioned objective, the present invention proposes a lamp device, which comprises a base, a lamp seat installed in the base, a circuit board, at least one USB interface, and a lamp shade hooding the lamp seat thereinside. The lamp seat is electrically connected with the circuit board. The USB interface includes a cartridge disposed in the base and a USB socket module disposed inside the cartridge. The USB socket module is separated from the circuit board and electrically connected with the circuit board through cables. The USB socket module includes at least one of Type-C USB sockets, Micro USB sockets, and Mini USB sockets. A wall of the cartridge, which is corresponding to the socket of the USB socket module, has at least one opening. The interface of an external USB data line can be passed through the opening and inserted into the socket of the USB socket module.

The present invention respectively disposes the USB socket module and the circuit board at different positions, whereby to reduce the size of the USB interface and decrease the space volume required for installing the USB interface. Therefore, the present invention can increase the flexibility of installing the USB interface (e.g. installing the USB interface in a smaller base) and improve the overall esthetics of the base.

The present invention proposes a lamp device.

Refer to FIGS. 1-4. In one embodiment, the lamp device of the present invention comprises a base 1, a lamp seat (not shown in the drawings) installed in the base 1, a circuit board 3, at least one USB interface 4, and a lamp shade 2 installed on the base 1. The lamp shade 2 hoods the lamp seat thereinside. The lamp seat is electrically connected with the circuit board 3, and a lamp is installed in the lamp seat. The circuit board 3 is electrically connected with a power source (not shown in the drawings) through a power cord. The power source may be commercial power or batteries. The USB interface 4 includes a cartridge 41 installed in the base 1 and a USB socket module 42 installed inside the cartridge 41. The USB socket module 42 is separated from the circuit board 3 and electrically connected with the circuit board 3 through cables 43. The USB socket module 42 includes at least one of Type-C USB sockets 421, Micro USB sockets 422, and Mini USB sockets (not shown in the drawings). As shown in FIG. 4, the USB socket module 42 includes a Type-C USB socket 421 and a Micro USB socket 422. Thereby, the USB interface 4 is reduced to a smaller size and requires less space for installation. Therefore, the position of installing the USB interface 4 has higher selectivity. For example, the USB interface 4 can be installed in a smaller base 1. Further, the overall esthetics of the base 1 is improved. A wall of the cartridge 41, which is corresponding to the socket of the USB socket module 42, has at least one opening 40. The interface of an external USB data line, such as a Type-C USB data line, a Micro USB data line, or a Mini USB data line, can be passed through the opening 40 and inserted into the socket of the USB socket module 42.

As shown in FIG. 1, in this embodiment, the base 1 includes a baseplate 11, a plurality of studs 12 installed on the baseplate 11, and a support platform 13 connected with the tops of the studs 12. The lamp seat is installed on the support platform 13. In one embodiment, four studs 12 are adopted and distributed in a rectangular way. In other embodiments, three, five, or more studs are used.

In the present invention, one or more USB interfaces 4 are used. In the embodiment shown in FIG. 1, there are two USB interfaces 4. The baseplate 11 and/or at least one stud 12 has an installation hole 10 for installing the cartridge 41. In installing the cartridge 41, the opening 40 is faced outward, whereby the interface of the external USB data line can be inserted into the socket of the USB socket module 42.

Refer to FIG. 4. In one embodiment, the cartridge 41 is made of plastic and includes a casing 411 whose one side is open and a cover 412 connected with the casing 411 and covering the casing 411. The casing 411 and the cover 412 are detachably connected with each other. For example, the casing 411 and the cover 412 are detachably connected with and each other via screws or press-fit mechanisms. Besides, the casing 411 and the cover 412 can be detachably connected with each other via pins and pin holes.

Refer to FIG. 3 and FIG. 4. In one embodiment, the cartridge 41 has avoidance recesses on at least one set of opposite sides. An elastic plate 413 is arched upward and connected with the front wall and the rear wall of the avoidance recess. While pressed, the elastic plate 413 is elastically deformed toward the avoidance recess. One surface of the elastic plate 413, which faces outward, has press-fit teeth 414 protruding outward. After the cartridge 41 is press-fitted into the installation hole 10, the press-fit teeth 414 press against the corresponding wall of the installation hole 10, whereby the cartridge 41 is tightly secured inside the installation hole 10.

In one embodiment, the bottom of the baseplate 11 has a recess 111. The circuit board 3 is disposed inside the recess 111. The side wall of the recess 111 has the installation hole 10 for installing the USB interface 4.
