Technical Field

[0001] The utility model provides a lampshade heat dissipation structure, belongs to the technical field of LED lamp equipment, and particularly relates to an LED lampshade heat dissipation structure. Background Art

[0002] LED lamps are lighting devices that use light emitting diodes (LEDs) as light sources. Compared with traditional bulbs, LED lamps have higher energy efficiency and longer service life. They can convert a larger proportion of electrical energy into light energy, but they also generate a certain amount of heat energy. The efficiency and life of LED lamps are closely related to their operating temperature. Excessive temperature will accelerate the light efficiency attenuation of LED chips and may cause early aging and damage of LED materials. Heat dissipation is crucial to the performance of LED lamps. A good heat dissipation system can effectively transfer the heat generated by LED lamps from the chip to the outside of the lamp, thereby maintaining the operating temperature of the LED within a safe range.

[0003] Existing heat sinks for LED lamps are mostly equipped with heat dissipation fans or heat sinks behind the wick, which increases the size of the LED lamp and the production cost. At the same time, for decorative atmosphere LED lamps, it not only reduces the aesthetics, but also the single lampshade structure lacks a certain interest. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an LED lampshade heat dissipation structure, comprising LED lamps distributed in layers, wherein the LED lamps are connected to adjustable heat dissipation plates arranged on both sides of the mounting belt through an annular mounting belt mounted on the outside of the LED lamps, the adjustable heat dissipation plates are provided with cross-distributed inclined surfaces, a driving plate corresponding to the inclined surfaces is provided above the adjustable heat dissipation, an outer shell body mounted on the outside of the adjustable heat dissipation is provided on the outside of the driving plate, and an adjustment rail corresponding to the inclined surfaces on the adjustable heat dissipation plate is provided on the outer shell body.

[0006] Preferably, the adjustable heat sink comprises an external heat sink closely attached to the outer shell, and an internal heat sink closely attached to the external heat sink, and the inclined surfaces on the external heat sink and the internal heat sink are cross-distributed.

[0007] Preferably: a first limiting ring is connected to one end of the external heat dissipation plate close to the mounting belt, a second limiting ring fixedly connected to the internal heat dissipation plate is provided below the first limiting ring, and a third limiting ring is provided on the side of the internal heat dissipation plate facing away from the second limiting ring, and the thickness of the third limiting ring is the same as the sum of the thicknesses of the first limiting ring and the second limiting ring.

[0008] Preferably: the driving plate is connected with staggered distribution and corresponding to the external heat dissipation plate and the inclined surface on the external heat dissipation plate on one side close to the adjustable heat dissipation plate, the other side of the driving plate is connected with the adjustable driving plate through a fixedly connected driving shaft, the adjustable driving plate is connected with a movable shaft fixedly connected to the driving shaft through a symmetrically fixedly connected rotating shaft sleeve, and the other side of the movable shaft is fixedly connected with a driving motor.

[0009] Preferably, the external heat sink and the internal heat sink are both provided with through grooves penetrating through the plates, the through grooves are arc-shaped with a certain angle of inclination, and a glass is installed on one side of the outer shell close to the adjustable heat sink.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] The utility model arranges an adjustable heat sink sleeved on the outside of the LED lamp, and with the help of a driving plate corresponding to the adjustable heat sink, drives the adjustable heat sink to rotate in an interlaced manner under the limit of the adjusting rail. Under the action of the mounting belt, the LEDs and the like will not rotate with the adjustable heat sink, and will continuously make interlaced contact, which is beneficial to the heat dissipation of the adjustable heat sink.

[0028] like Figure 1 and Figure 2As shown, a heat dissipation structure of an LED lamp cover comprises LED lamps 1 arranged in layers, an annular mounting belt 11 sleeved on the outside of the LED lamp 1 is connected to an adjustable heat dissipation plate 2 arranged on both sides of the mounting belt 11, the adjustable heat dissipation plate 2 comprises an external heat dissipation plate 24 close to an outer shell 12, and an internal heat dissipation plate 25 close to the external heat dissipation plate 24, the inclined surfaces 21 on the external heat dissipation plate 24 and the internal heat dissipation plate 25 are cross-distributed, the adjustable heat dissipation plate 2 is provided with the cross-distributed inclined surfaces 21, a driving plate 22 corresponding to the inclined surfaces 21 is provided above the adjustable heat dissipation 2, an outer shell 12 sleeved on the outside of the adjustable heat dissipation 2 is provided on the outside of the driving plate 22, and an adjusting rail 23 corresponding to the inclined surface on the adjustable heat dissipation plate 2 is provided on the outer shell 12

[0029] In the present embodiment, an adjustable heat sink 2 is provided which is sleeved on the outside of the LED lamp 1, and with the help of a driving plate 22 corresponding to the adjustable heat sink 2, the adjustable heat sink 2 is driven to rotate in an interlaced manner under the limitation of the adjustment rail 23. Under the action of the mounting belt 11, the LEDs 1 will not rotate with the adjustable heat sink 2, and will continuously make interlaced contact, which is beneficial to the heat dissipation of the adjustable heat sink 2. At the same time, the adjustable heat sink 2 plays a role similar to a lampshade, that is, it can block light and also play a limiting role for the LED lamp 1. Generally speaking, the utility model not only increases the fun but also avoids the increase in volume due to the heat dissipation device.

[0030] like Figure 3 , 4 5, the end of the external heat sink 24 close to the mounting belt 11 is connected to a first limiting ring 211, and a second limiting ring 212 fixedly connected to the internal heat sink 25 is provided below the first limiting ring 211. A third limiting ring 213 is provided on the side of the internal heat sink 25 away from the second limiting ring 212. The thickness of the third limiting ring 213 is the same as the sum of the thickness of the first limiting ring 211 and the second limiting ring 212. The side of the driving plate 22 close to the regulating heat sink 2 is connected with staggered distributions and the inclined surfaces on the external heat sink 24 and the external heat sink 25 are respectively 21 corresponding to the card plate 221, the other side of the driving plate 22 is connected with the adjusting driving plate 223 through the fixedly connected driving shaft 222, the adjusting driving plate 223 is connected with a movable shaft 225 fixedly connected to the driving shaft 222 through a symmetrically fixedly connected rotating shaft sleeve 224, the other side of the movable shaft 225 is fixedly connected with a driving motor 226, the external heat dissipation plate 24 and the internal heat dissipation plate 25 are respectively provided with through grooves 26 penetrating themselves, the through grooves 26 are arc-shaped with a certain angle of inclination, and glass is installed on the side of the outer shell 12 close to the adjustable heat dissipation plate 2.

[0031] In this embodiment, when the driving motor 226 drives the movable shaft 225 to rotate, the adjusting driving plate 223 can be driven to rotate together with the help of the rotating shaft sleeve 224. At the same time, when the driving adjusting plate 223 moves along the adjusting rail 23, when rising or falling, the movable shaft 225 rotates in the rotating shaft sleeve 224, and the adjusting driving plate 223 drives the driving plate 22 to tilt together with the driving shaft 222, so that the card plate 221 is tilted to match the inclined surface 21. As the tilting direction of the card plate 221 along the adjusting rail 23 is inconsistent, the external heat sink 24 and the internal heat sink 25 are driven to rotate respectively, thereby driving the surrounding air flow with the help of the through groove 26 on itself to assist in heat dissipation; the external heat sink 24 rotates on the second limiting ring 212 on the internal heat sink 25 with the help of the first limiting ring 211, and the second limiting ring 212 is close to the glass wall on the outer shell 12, and the mounting belt 11 is placed on the third limiting ring 213 and the first limiting ring 211.

[0032] When in use, install the LED lamp 1 on the annular mounting belt 11. Ensure that the LED lamp is fixed and in the correct position, install the outer shell 12, and ensure that it is outside the adjustable heat sink 2 to provide protection and structural support for subsequent operations; assemble the external heat sink 24 and the internal heat sink 25 on the adjustable heat sink 2 so that the inclined surfaces 21 of the two are cross-distributed, install the drive plate 22 above the adjustable heat sink 2, and connect it to the inclined surfaces 21 of the external heat sink 24 and the internal heat sink 25 through the clamping plate 221, and fix the drive shaft 222 and the adjustable drive plate 223 to ensure that the rotating shaft sleeve 224, the movable shaft 225 and the drive motor 226 are correctly assembled; start the drive motor 226, which drives the movable shaft 225 and the adjustable drive plate 223 to rotate, The rotation of the adjusting driving plate 223 will drive the external heat sink 24 and the internal heat sink 25 to rotate through the tilting operation of the driving plate 22. The design of the inclined surface 21 enables the heat sink to effectively promote the flow of air during the rotation process, and drives the surrounding airflow through the through groove 26, so as to achieve the heat dissipation effect; observe the reaction of the adjusting rail 23 to ensure that the tilting and rotation operation of the heat sink is uniform and effective, adjust the speed of the driving motor 226 to control the rotation speed of the heat sink, and adjust it according to the actual heat dissipation needs; regularly check all moving parts and circuit connections to ensure that there is no looseness or wear, and ensure that the glass hydrocarbon part of the outer shell 12 is intact to prevent dust and other contaminants from entering the structure. The heat dissipation structure design of this LED lamp not only optimizes the heat dissipation effect, but also increases the overall functionality and interest of the device, and improves the efficiency and adjustability of use.

[0033] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
