In order to realize the improvement of the assembling reliability of an LED lamp in a tiny device such as an endoscope and the automatic production, the embodiment of the invention provides an endoscope. For example, referring to fig. 4-12, the endoscope comprises: lens assembly 1, conductive base and lighting assembly 2. It will be appreciated that the endoscope has a housing, although not shown. The lens assembly 1, the conductive base, the lighting assembly and the like are typically disposed at least partially within the housing defined by the housing. The housing may take any suitable shape and configuration. In one embodiment, the housing is split from two half shells. The conductive base may be fixedly attached to the housing in any suitable manner. It should be noted that, the embodiment in which the lens end surface 11 of the lens assembly 1 and/or the light emitting surface 23 of the illumination assembly are directly exposed outside the housing is also within the scope of the present invention.

It should be noted that an "assembly" is a combination of parts, and the number of parts in the combination may be one, two or more.

The conductive base is fixedly mounted to a housing of the endoscope and has an external lead. The conductive base may take any suitable form and may for example be a PCB board 5 and may also be a conductive base frame 6. The PCB 5 and the conductive base frame 6 are provided with external leads which can supply power to the lens assembly 1 and the lighting assembly 2 and transmit image signals and/or control signals and the like. The conductive base is used for electrically connecting the lens assembly 1 and the lighting assembly 2, and can also provide structural support and fixation for the lighting assembly and/or the lens assembly as a fixed base or a mounting base according to requirements. The specific material, circuit, shape, size and the like of the conductive base can be set as required.

The lens assembly 1 is used to collect an in vivo image. The lens assembly 1 is fixedly connected to the conductive base and is electrically connected to the conductive base. The connection may be direct or indirect via an intermediate frame or the like. The specific shape, size, specification, etc. of the lens assembly 1 can be selected or set as desired. In the illustrated embodiment, only one lens is illustrated, and 2 or more lenses may be employed. The lens assembly 1 includes, for example, an optical lens and a CMOS imaging chip.

A lighting assembly 2 is used for lighting, the lighting assembly 2 being fixedly connected to the electrically conductive base and being electrically connected to the electrically conductive base. More specifically, the acquisition of in vivo images is illuminated. The particular shape, size, format, etc. of the lighting assembly 2 may be selected or arranged as desired. For example, the lighting assembly may employ LED lamps as the light source, and the number, specification, arrangement, and the like of the LED lamps may be set as desired. For example, one, two, three, four, or more LED lamps may be selected as the illumination assembly.

Referring to fig. 2, the first LED lighting assembly 21 and the second LED lighting assembly 22 are horizontally fixed at two sides of the lens module 1 and between the upper and lower end surfaces of the lens module 1.

The lighting assembly 2 extends parallel to the optical axis direction of the lens assembly 1, and the light-emitting surface 23 of the lighting assembly 2 does not exceed the lens end surface 11 of the lens assembly 1. Thereby, it is advantageous to avoid that the light of the illumination module 2 is directly incident into the lens module. The optical axis direction of the lens assembly 1 is, for example, the up-down direction in fig. 4. The illumination assembly 2 extends parallel to the optical axis direction of the lens assembly 1, which means that the light-emitting central axis of the illumination assembly 2 is substantially parallel to the optical axis direction of the lens assembly 1, for example, the included angle between the two is less than or equal to 15 degrees, or even less than or equal to 30 degrees.

As mentioned before, the conductive base can be a PCB board 5 with PCB board leads 33 on one side of the PCB board 5. In case the electrically conductive base can be a PCB board 5, an electrically conductive intermediate shelf 4 is provided to fixedly, electrically conductively connect the lighting assembly 2 to the PCB board 5. In particular, the conductive intermediate shelf 4 comprises a conductive connector. The conductive connector extends in parallel to the optical axis direction of the lens assembly 1, supports the lighting assembly 2 on the PCB board 5, and electrically connects the lighting assembly 2 to the PCB board 5.

The first LED lighting assembly 21 and the second LED lighting assembly 21 are respectively fixed on the top of the first conductive connector 41 and the second conductive connector 42 through conductive materials, and the connection surfaces are respectively B1 and B2.

In this embodiment, the thin wire is replaced with a conductive intermediate frame 4. The conductive intermediate frame 4 simultaneously realizes the conductive connection of the first LED light-emitting component 21 and the second LED light-emitting component 22, and the assembly of the first LED light-emitting component 21, the second LED light-emitting component 22 and the PCB 6, so that the relative positioning of the LED light-emitting components and the lens module 1 is realized.

Referring to fig. 3, the pad 51 on the upper end surface of the PCB 5 is electrically connected to the inside of the pad on the lower end surface of the PCB 5. The PCB lead 33 (external connection) is soldered on a pad on the lower end face of the PCB, and the soldering point is C, so that the power supply input of the LED light-emitting component and the output of the image information of the lens module 1 are realized.
