Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to an LED light source with a new structure. Background Art

[0002] With the advancement of technology, the luminous efficiency of LED light sources has been continuously improved, and has gradually approached or even exceeded traditional light sources such as fluorescent lamps and incandescent lamps. This makes the application of LED light sources in the field of lighting more extensive and feasible. LED light sources have the advantages of small size, long life, and high efficiency. Its luminous efficiency is much higher than that of traditional light sources, and its spectral range is narrow, monochromaticity is good, and it can directly emit colored visible light without filtering.

The LED lamp of the utility model can adjust the lighting range and lighting brightness, has strong decorative performance, is dynamic and interesting, has a beautiful structure, and is easy to assemble and disassemble.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] In the prior art, if each rotatable lamp stand needs to be adjusted individually, then the user needs to adjust the lighting angles of multiple lamp stands one by one, which is not only time-consuming and laborious, but also prone to inconsistent angles, affecting the overall lighting effect. Individually adjusting each rotatable lamp stand requires the user to perform multiple operations and requires precise control of the angle of each adjustment, which may be difficult for non-professional users and increases the complexity and inconvenience of use. Since each lamp stand is adjusted independently, it is difficult to ensure that the angles of all lamp stands are completely consistent after adjustment, which will cause uneven brightness in the lighting area and affect the lighting quality.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-8 , the utility model provides a technical solution: Example

[0030] A new type of LED light source is mainly composed of a lamp holder body 1, a lamp panel 2, a main LED light source 3, a rotatable lamp holder 5, a secondary LED light source 6, a threaded heat dissipation groove 7, an adjustment mechanism, a battery compartment 8 and an end cover 9. The lamp holder body 1 is used as a supporting structure for the entire light source, and a lamp panel 2 is fixedly installed on its bottom surface, and a main LED light source 3 as a main light source is fixedly arranged on the lamp panel 2. In order to further improve the lighting effect, a number of rotation grooves 4 are also designed on the lamp panel 2, and these rotation grooves 4 are distributed in a circumferentially equidistant array, which provides a basis for the flexible rotation of the rotatable lamp holder 5.

[0031] A rotatable lamp holder 5 is rotatably disposed in each rotating slot 4, and a plurality of auxiliary LED light sources 6 are fixedly mounted on the lamp holders. When the lighting angle needs to be adjusted, the rotatable lamp holder 5 can rotate in the rotating slot 4, thereby driving the auxiliary LED light source 6 to change the irradiation direction, thereby realizing multi-angle lighting. This design not only increases the flexibility of the light source, but also can provide a more uniform lighting effect in different scenes.

[0032] Considering that the LED light source will generate a certain amount of heat during operation, the present invention provides threaded heat dissipation grooves 7 on the side wall of the lamp holder body 1. These heat dissipation grooves can not only increase the heat dissipation area, but also accelerate the heat dissipation by air convection, effectively ensuring the stability and service life of the light source.

[0033] In order to achieve accurate adjustment of the lighting angle, the present invention is specially designed with a set of adjustment mechanisms. The mechanism mainly includes 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 installed on the side wall of the rotating ring 12. Each rotating seat 13 is rotatably connected to a connecting rod 14, and the other end of these connecting rods 14 is rotatably connected to the rotatable lamp holder 5.

[0034] When the lighting angle needs to be adjusted, the user only needs to rotate the nut ring 10. As the nut ring 10 rotates, it will drive the rotating ring 12 to move up and down along the axis of the lamp holder body 1. Since the rotating ring 12 and the connecting rod 14 are rotatably connected, the movement of the rotating ring 12 will further drive all the rotatable lamp frames 5 to rotate synchronously in the rotating groove 4 through the connecting rod 14. In this way, the user can achieve precise adjustment of the lighting angle to meet different lighting needs.

[0035] In order to ensure the portability and endurance of the light source, the present invention has a battery compartment 8 inside the lamp holder body 1 for installing batteries or other power modules. At the same time, an end cap 9 is threadedly connected to the top of the lamp holder body 1 to close the battery compartment 8 and protect the internal components from external interference. Example

[0036] Based on the first embodiment, this embodiment further optimizes and expands the structure and function of the LED light source, aiming to improve the light weight, adjustment convenience, carrying flexibility and heat dissipation efficiency of the light source. The following is a detailed description of the specific optimization content:

[0037] In order to reduce the overall weight and reduce the material cost, the present embodiment opens a plurality of weight-reducing holes 15 on the connecting rod 14. These weight-reducing holes 15 are evenly distributed on the connecting rod 14 in a linear array, which not only ensures the strength and stability of the connecting rod 14, but also effectively reduces its mass, making the entire light source device lighter, easier to carry and operate.

[0038] In order to facilitate the user to adjust the lighting angle more accurately, in this embodiment, an adjustment ring 16 is fixedly provided on the nut ring 10. A plurality of arc-shaped grooves 17 are provided on the adjustment ring 16. The user can insert fingers or tools into the arc-shaped grooves 17 to easily rotate the nut ring 10, thereby driving the rotatable lamp holder 5 to rotate. This design not only improves the convenience of adjustment, but also increases the comfort of user operation.

[0039] In order to improve the carrying flexibility of the light source, in this embodiment, a connecting ring 18 is fixedly provided on the top of the end cover 9, and a buckle 19 is rotatably provided on the connecting ring 18. When the user needs to hang the light source on a rope or a long pole, the buckle 19 can be easily hung by fixing it on the top of the end cover 9. In addition, the end cover 9 adopts a hollow design, and a cover plate 20 is provided on the top by a threaded connection. When the light source needs to be adsorbed on a metal object, the user can reverse the cover plate 20 (at this time, the buckle 19 is hidden inside the end cover 9) to expose the magnet 21 fixed on the cover plate 20, and use the adsorption force of the magnet 21 to fix the light source in the desired position. This design allows the light source to be used flexibly in different scenarios, greatly improving its practicality.

[0040] In order to further improve the heat dissipation efficiency of the light source, in this embodiment, main heat sinks 22 are fixedly arranged on both sides of the rotatable lamp frame 5 along the auxiliary LED light source 6. These main heat sinks 22 can effectively increase the heat dissipation area and accelerate the heat dissipation. In addition, in order to further improve the heat dissipation effect, auxiliary heat sinks 23 are also fixedly arranged on the back of the main heat sink 22. The auxiliary heat sink 23 cooperates with the main heat sink 22 to form a more efficient heat dissipation system, ensuring that the light source can maintain a stable working state during long-term use.

[0041] Working principle: During the use of the utility model, when the user needs to adjust the scattered illumination area and angle of the light source, the adjustment mechanism is activated 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 thereof to move up and down along the axis direction of the lamp holder 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 rotatably connected to each rotating seat 13. The other ends of these connecting rods 14 are rotatably connected to the rotatable lamp holder 5. Due to the rotatable connection between the rotating ring 12 and the connecting rod 14, the up and down movement of the rotating ring is converted into the rotational movement of the rotatable lamp holder 5 in the rotating groove 4 through the connecting rod 14. Therefore, the user can synchronously adjust the rotation angle of all the rotatable lamp holders 5 by rotating the nut ring 10, so as to achieve precise adjustment of the lighting angle. At the same time, the angle adjustment of multiple rotatable lamp holders 5 can be achieved by only rotating the nut ring 10, which greatly improves the adjustment efficiency.

[0042] When the user needs to hang the light source on a rope or a long pole, the user only needs to fix the buckle 19 on the top of the end cover 9 to easily achieve the hanging. In addition, the end cover 9 adopts a hollow design, and a cover plate 20 is provided on the top by a threaded connection. When the light source needs to be adsorbed on a metal object, the user can reverse the cover plate 20 (at this time, the buckle 19 is hidden inside the end cover 9) to expose the magnet 21 fixed on the cover plate 20, and use the adsorption force of the magnet 21 to fix the light source at the desired position.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
