The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figure 1-4 As shown, a detachable lamp cap structure of the present embodiment includes a metal hose 1, a lamp assembly structure and a lens barrel 5. The metal hose 1, the lamp assembly structure and the lens barrel 5 of the utility model are arranged in sections, and the three-part structure is easy to disassemble and install by threaded connection. When one of the parts needs to be replaced and fails, it can be replaced separately, avoiding overall replacement, which is more economical. When packaging and transportation are required, the metal hose 1, the lamp assembly structure and the lens barrel 5 can be packaged separately. At this time, the volume and shape of each package are consistent. At the same time, different packaging standards can be set for different parts, which is convenient for packaging and transportation.

[0025] The end of the metal hose 1 close to the lamp group structure is fixedly connected to the hose upper seat 2, and a conductive sliding disc 21 is arranged inside the hose upper seat 2. The end of the metal hose 1 away from the hose upper seat 2 is fixedly connected to the hose lower seat 6, and a locking nut 61 is threadedly connected to the hose lower seat 6. In this embodiment, the conductive sliding disc 21 is arranged to facilitate the power supply connection of the lighting source in the lamp group structure.

[0026] The lamp holder structure includes a radiator 3 and a light source 7. The light source 7 is fixed to the end of the radiator 3. One end of the radiator 3 provided with the light source 7 is threadedly connected to the lens barrel 5. The other end of the radiator 3 is threadedly connected to the upper seat 2 of the hose. A plurality of contact pins 31 are fixedly connected to the end of the radiator 3 away from the light source 7. The contact pins 31 are electrically connected to the light source 7. When the radiator 3 is threadedly connected to the upper seat 2 of the hose, the contact pins 31 can abut against the conductive sliding disk 21. In this embodiment, the interior of the radiator 3 is a hollow structure for wiring. The contact pins 31 are fixedly connected to the PCB board, and the PCB board is fixed together with the contact pins 31, wherein the PCB board and the light source 7 are connected by wires. The radiator 3 is cylindrical, and a plurality of heat dissipation protrusions 301 are formed on the outer surface of the radiator 3.

[0027] An illuminated space is formed between the lens barrel 5 and the radiator 3. The lamp cap structure includes a light guide ring 4, which is sleeved on the end of the radiator 3. A plurality of light guide protrusions 41 are formed on the light guide ring 4. The light guide protrusions 41 extend into the illuminated space, and the light guide protrusions 41 are used to guide the light to the light guide ring 4. A light guide surface 411 is formed on the light guide protrusion 41, which is inclined from the middle of the radiator 3 to the outside. The light generated by the light source 7 reaches the light guide ring 4 through the reflection of the light guide surface 411. The light guide ring 4 is located between the lens barrel 5 and the radiator 3 in appearance, and its function is to indicate the lighting state of the light source 7. The lens barrel 5 will gather the light to the light emitting side of the lens barrel 5. Therefore, after using the light guide ring 4, the light state of the light source 7 can be observed in multiple directions. The light guide protrusions 41 on the light guide ring 4 divide the thread at the end of the radiator 3 into multiple thread segments, which is convenient for achieving the purpose of light guidance and will not affect the connection effect between the radiator 3 and the lens barrel 5.

[0028] The lens barrel 5 is in a conical shape. A lens group 51 is arranged in the lens barrel 5, and the lens group 51 includes one or more lenses 51, and the multiple lenses 51 are arranged along the light emitting direction. Spacers 52 are arranged between the multiple lenses 51 to facilitate the adjustment of the light emitting direction. By arranging different lens groups 51, light rays with different convergence degrees can be obtained.
