The lamp holder body 1 is used as a supporting structure of the whole light source, the lamp panel 2 is fixedly arranged on the bottom surface of the lamp holder body, and the main LED light source 3 serving as a main light emitting source is fixedly arranged on the lamp panel 2. In order to further improve the lighting effect, the lamp panel 2 is further provided with a plurality of rotating grooves 4, and the rotating grooves 4 are distributed in a circumferential equidistant array manner, so that a foundation is provided for flexible rotation of the rotatable lamp holder 5.

Each rotating groove 4 is rotatably provided with a rotatable lamp holder 5, and a plurality of auxiliary LED light sources 6 are fixedly arranged on the lamp holders. When the illumination angle needs to be adjusted, the rotatable lamp bracket 5 can rotate in the rotary groove 4, so that the auxiliary LED light source 6 is driven to change the illumination direction, and multi-angle illumination is realized. This design not only increases the flexibility of the light source, but also provides a more uniform lighting effect in different scenes.

Considering that the LED light source can generate certain heat in the working process, the invention is provided with the threaded heat dissipation groove 7 on the side wall of the lamp holder main body 1. The radiating grooves can not only increase radiating area, but also accelerate heat dissipation in an air convection mode, so that the stability and the service life of the light source are effectively ensured.

In order to realize accurate adjustment of the illumination angle, the invention particularly designs a set of adjusting mechanism. The mechanism mainly comprises a nut ring 10 rotatably arranged on the threaded heat dissipation groove 7, an annular groove 11 arranged on the side wall of the nut ring 10, a rotating ring 12 rotatably arranged in the annular groove 11 and a plurality of rotating seats 13 fixedly arranged on the side wall of the rotating ring 12. Each rotating seat 13 is rotatably connected with a connecting rod 14, and the other ends of the connecting rods 14 are rotatably connected with the rotatable lamp holders 5.

When it is desired to adjust the illumination angle, the user only rotates the nut ring 10. As the nut ring 10 rotates, it will drive the rotating ring 12 to move up and down along the axial direction of the socket body 1. Because the rotating ring 12 is in rotating connection with the connecting rod 14, the rotating ring 12 can further drive all the rotatable lamp holders 5 to synchronously rotate in the rotating groove 4 through the connecting rod 14. In this way, the user can realize accurate adjustment of the illumination angle, and different illumination requirements are met.

In order to ensure portability and cruising ability of the light source, the invention is provided with a battery compartment 8 in the lamp holder main body 1 for installing batteries or other power modules. At the same time, an end cap 9 is screwed to the top of the socket body 1 to close the battery compartment 8 and protect the internal components from external interference.

Examples

In order to facilitate the user to more precisely adjust the illumination angle, an adjusting ring 16 is fixedly provided on the nut ring 10 in this embodiment. The adjusting ring 16 is provided with a plurality of arc grooves 17, and a user can insert the adjusting ring into the arc grooves 17 through fingers or tools to easily rotate the nut ring 10, so as to drive the rotatable lamp holder 5 to rotate. The design not only improves the convenience of adjustment, but also increases the comfort of user operation.

In order to improve the portability of the light source, the present embodiment fixedly provides a connection ring 18 on the top of the end cap 9, and rotatably provides a buckle 19 on the connection ring 18. When a user needs to hang the light source on the rope or the long rod, the hanging can be easily realized by only fixing the buckle 19 on the top of the end cover 9. In addition, the end cap 9 is of hollow design, and the top is provided with a cover plate 20 in a threaded connection manner. When the light source is required to be adsorbed on the metalware, the user can reversely position the cover plate 20 (at the moment, the buckle 19 is hidden in the end cover 9) to expose the magnet 21 fixed on the cover plate 20, and the adsorption force of the magnet 21 is utilized to fix the light source at the required position. The design enables the light source to be flexibly used in different scenes, and the practicability of the light source is greatly improved.

In order to further improve the heat dissipation efficiency of the light source, the main heat dissipation fins 22 are fixedly arranged on the two sides of the rotatable lamp holder 5 along the auxiliary LED light source 6. These main fins 22 can effectively increase the heat radiation area and accelerate the heat radiation. In addition, in order to further enhance the heat dissipation effect, the back surface of the main fin 22 is fixedly provided with a sub fin 23. The auxiliary radiating fins 23 are matched with the main radiating fins 22 to form a more efficient radiating system, so that the light source can be ensured to maintain a stable working state in the long-time use process.

Working principle when the utility model is used, when a user needs to adjust the scattering irradiation area and angle of a light source, an adjusting mechanism is started by rotating the nut ring 10, the rotation of the nut ring 10 drives the rotating ring 12 in the annular groove 11 on the side wall of the nut ring to move up and down along the axis direction of the lamp holder main body 1, a plurality of rotating seats 13 are fixed on the side wall of the rotating ring 12, and a connecting rod 14 is connected on each rotating seat 13 in a rotating way. The other ends of these connecting rods 14 are rotatably connected to the rotatable lamp holders 5. Due to the rotational connection between the rotating ring 12 and the connecting rod 14, the up-and-down movement of the rotating ring is converted into a rotational movement of the rotatable lamp holder 5 in the rotating groove 4 by the connecting rod 14. Therefore, the user can synchronously adjust the rotation angles of all the rotatable lamp holders 5 by rotating the nut ring 10, so that the accurate adjustment of the illumination angle is realized, and meanwhile, the angle adjustment of a plurality of the rotatable lamp holders 5 can be realized by only rotating the nut ring 10, so that the adjustment efficiency is greatly improved.

When a user needs to hang the light source on the rope or the long rod, the hanging can be easily realized by only fixing the buckle 19 on the top of the end cover 9. In addition, the end cap 9 is of hollow design, and the top is provided with a cover plate 20 in a threaded connection manner. When the light source is required to be adsorbed on the metalware, the user can reversely position the cover plate 20 (at the moment, the buckle 19 is hidden in the end cover 9) to expose the magnet 21 fixed on the cover plate 20, and the adsorption force of the magnet 21 is utilized to fix the light source at the required position.
