Embodiment

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 6 In this embodiment, an internally-mounted lamp head is provided, which includes a heat dissipation plate 1, a spotlight bead 3, a floodlight bead 2, a spotlight cup 3, a spotlight cover 5, a floodlight cover 6, a housing 10, and a switching component. On both sides of the heat dissipation plate 1, a spotlight bead 3 and a floodlight bead 2 are respectively installed. The heat dissipation plate 1 is also provided with screw 7 holes. The spotlight cup 3 is conical, with openings at both the top and bottom and a hollow interior. Outside the spotlight cup 3, there is a screw hole column 8. The small opening of the spotlight cup 3 is sleeved outside the spotlight bead 3. The screw 7 passes through the screw 7 hole of the heat dissipation plate 1 and the screw hole column 8 of the spotlight cup 3 to fix the two together. The floodlight cover 6 is hemispherical, and on the outside, there is a snap ring 22. The spotlight cover 5 is circular, and on the outside, there is a snap ring 22. The housing 10 is sleeved outside the housing 9. The switching component includes a housing 9, a rotating shaft 11, and a transmission gear 13. The housing 9 is spherical, with a hollow interior and openings at both the top and bottom. On the inner sides of both openings, there are snap grooves 12. The rotating shaft 11 and the transmission gear 13 are fixed on both sides of the outer surface of the housing 9. The rotating shaft 11 and the transmission gear 13 are arranged opposite to each other at 180°. In this embodiment, it is preferably that the rotating shaft 11 and the transmission gear 13 are integrally formed with the housing 9. On the outer surface of the housing 9 between the rotating shaft 11 and the transmission gear 13, a limiting block 15 is fixed. The housing 10 is cylindrical, and on one end of the inner wall, there is a ring of transmission racks 14. The heat dissipation plate 1, the spotlight bead 3, the floodlight bead 2, and the spotlight cup 3 are arranged inside the housing 9. The spotlight cover 5 and the floodlight cover 6 are respectively arranged outside the floodlight bead 2 and the spotlight cup 3, and are fixed on the housing 9 through the cooperation of the snap ring 22 and the snap groove 12. On the lamp housing, there are grooves 24 corresponding to the rotating shaft 11 and the transmission gear 13. The rotating shaft 11 and the transmission gear 13 are snapped into the grooves 24 and can rotate within the grooves 24.

[0023] An in-built lamp holder provided in this embodiment, when in use, the outer housing 10 is sleeved outside the housing 9, the transmission rack 14 meshes with the transmission gear 13, and rotating the outer housing 10 can cause the transmission rack 14 to drive the transmission gear 13 to rotate in the groove 24. Since the transmission gear 13 is fixed on the housing 9 and will not rotate relatively, the housing 9 is driven to flip around the rotation axis 11 to realize the switching between the spotlight bead 3 and the floodlight bead 2, so that the in-built lamp holder has the functions of both floodlight and spotlight at the same time. The user can rotate the housing 9 to realize the switching of the light, and the limiting block 15 on the housing 9 ensures that the maximum rotation range of the housing 9 is half a circle. The lamp holder structure is compact and reasonable. This kind of lamp holder can be installed in various portable lighting lamps, making the whole portable lighting lamp structure more compact, reducing the production and transportation costs, and enhancing the market competitiveness of the product. Embodiment

[0024] Please refer to Figure 3 , an in-built lamp holder provided in this embodiment, compared with the technical solution of Embodiment 1, can be improved as follows: The switching component is composed of the housing 9, the screw rod 17, the rotation axis 11 and the bevel gear 16. The rotation axis 11 and the bevel gear 16 are fixed on both sides of the outer surface of the housing 9, and the rotation axis 11 and the bevel gear 16 are arranged relatively at 180°. In this embodiment, it is preferably that the rotation axis 11 and the bevel gear 16 are integrally formed with the housing 9. The rotation axis 11 and the bevel gear 16 are clamped in the groove 24 on the lamp housing and can rotate in the groove 24. There is a small hole (not shown in the figure) on the outer housing 10 for the screw rod 17 to pass through. One end of the screw rod 17 is provided with a bevel gear 16. After the end of the screw rod 17 provided with the bevel gear 16 passes through the small hole on the outer housing 10, it meshes with the bevel gear 16 on the housing 9. The other end of the screw rod 17 is exposed outside the outer housing. Rotating the screw rod 17 can drive the bevel gear 16 on the housing 9 to rotate in the groove 24 on the lamp housing through the meshing of the bevel gears 16. Since the bevel gear 16 is fixed on the housing 9 and will not rotate relatively, the housing 9 is driven to flip around the rotation axis 11 to realize the switching between the spotlight bead 3 and the floodlight bead 2. Embodiment

[0025] Please refer to Figure 4, an in-built lamp holder provided in this embodiment can be improved as follows compared with the technical solution of Embodiment 1: The switching component is composed of a housing 9, a pull ring 19, a rotating shaft 11 and a pull ring shaft 18. The rotating shaft 11 and the pull ring shaft 18 are fixed on both sides of the outer surface of the housing 9, and the rotating shaft 11 and the pull ring shaft 18 are arranged relatively at 180°. In this embodiment, it is preferably that the rotating shaft 11 and the pull ring shaft 18 are integrally formed with the housing 9. The rotating shaft 11 and the pull ring shaft 18 are clamped in the groove 24 on the lamp housing and can rotate in the groove 24. There is a small hole (not shown in the figure) on the outer housing 10 for the pull ring shaft 18 to pass through. One end of the pull ring shaft 18 that is not fixed to the housing 9 passes through the small hole on the outer housing 10 and exposes outside the outer housing. The pull ring 19 is fixed to the end of the pull ring shaft 18 that exposes outside the outer housing. Rotating the pull ring 19 can drive the pull ring shaft 18 to rotate in the groove 24 on the lamp housing. Since the pull ring shaft 18 is fixed to the housing 9 and will not rotate relatively, the housing 9 is driven to flip around the rotating shaft 11 to realize the switching between the spotlight bead 3 and the floodlight bead 2. Embodiment

[0026] Please refer to Figure 5 , an in-built lamp holder provided in this embodiment can be improved as follows compared with the technical solution of Embodiment 1: The switching component is composed of a housing 9, a knob 21, a rotating shaft 11 and a knob seat 23. The rotating shaft 11 and the knob seat 23 are fixed on both sides of the outer surface of the housing 9, and the rotating shaft 11 and the knob seat 23 are arranged relatively at 180°. In this embodiment, it is preferably that the rotating shaft 11, the knob seat 23 and the housing 9 are integrally formed. The rotating shaft 11 and the knob seat 23 are clamped in the groove 24 on the lamp housing and can rotate in the groove 24. There is a knob hole on the knob seat 23, and there is a small hole (not shown in the figure) on the outer housing 10 for the knob 21 to pass through. One end of the knob 21 passes through the small hole on the outer housing 10 and is inserted into the knob hole 20 to be connected with the knob seat 23, and the other end of the knob 21 exposes outside the outer housing. Rotating the knob 21 can drive the knob seat 23 to rotate in the groove 24 on the lamp housing. Since the knob seat 23 is fixed to the housing 9 and will not rotate relatively, the housing 9 is driven to flip around the rotating shaft 11 to realize the switching between the spotlight bead 3 and the floodlight bead 2.

[0027] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and variations can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
