Technical Field

[0001] The utility model relates to the technical field of heat dissipation of light-emitting diodes, and particularly to an LED light-emitting diode with a heat dissipation structure. Background Technique

[0002] A light-emitting diode, abbreviated as LED, is a commonly used light-emitting device that emits light by the recombination of electrons and holes, and it is widely used in the field of lighting.

[0003] The light-emitting diode can efficiently convert electrical energy into light energy and has a wide range of uses in modern society, such as lighting, flat panel display, medical devices, etc.

[0004] The traditional LED light-emitting diodes generally have a single heat dissipation and poor heat dissipation effect. When the LED is working, heat will be generated. If the heat dissipation is not good, the heat will accumulate around the LED chip. The increase in temperature will cause the electrons inside the LED chip to move more intensively, which may affect the electrical characteristics and lifespan of the LED. The luminous efficiency and photoelectric conversion efficiency of the LED are greatly affected by temperature. If the temperature is too high, the efficiency of the LED may decrease, resulting in a reduction in the optical power generated per unit of electrical power and affecting its brightness performance in practical applications.

[0005] In view of this, there is an urgent need for an LED light-emitting diode with a heat dissipation structure to improve the deficiencies of the existing technology. Summary of the Utility Model

The other end of the connection component is fixedly connected to a heat dissipation component for dissipating heat from the lamp bead. A fan component is fixedly connected to the surface of the connection component for assisting the heat dissipation of the heat dissipation component.

[0008] As a further improvement of this technical solution, the connection component includes a bracket. One end of the bracket is fixedly connected to the lamp holder, and a through hole is arranged at one end of the bracket. A bolt is threadedly connected at the through hole, and one end of the bracket is fixedly connected to the heat dissipation component through the bolt.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For the LED light-emitting diode with a heat dissipation structure, a heat dissipation component and a fan component are provided. The good heat dissipation design can effectively reduce the working temperature of the LED, thereby improving the photoelectric conversion efficiency and electrical performance stability of the LED.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment

[0023] Please refer to Figures 1-4 As shown, this embodiment provides an LED light-emitting diode with a heat dissipation structure, including an LED component 1. The LED component 1 includes a lamp holder 11. A cavity is provided inside the lamp holder 11 for filling a heat dissipation liquid. One side of the lamp holder 11 is fixedly connected to a lamp bead 10. The other side of the lamp holder 11 away from the lamp bead 10 is fixedly connected to a connection component 2. The other end of the connection component 2 is fixedly connected to a heat dissipation component 3. The heat dissipation component 3 is used for dissipating heat from the lamp bead 10. The surface of the connection component 2 is fixedly connected to a fan assembly 4. The fan assembly 4 is used for assisting the heat dissipation of the heat dissipation component 3.

[0024] The above working principle: When the LED light-emitting diode is operating normally, the lamp bead 10 generates heat, and the heat is transferred to the lamp holder 11 through heat conduction. There is a cavity inside the lamp group, and a coolant is filled inside the cavity. The coolant enters from the lower part of the lamp holder 11 and flows out from the upper part. The flowing-out coolant enters the heat dissipation component 3. The heat dissipation component 3 cools down the coolant, and the fan assembly 4 assists the heat dissipation component 3 to cool down the coolant, so as to continuously cool down the LED light-emitting diode during lighting.

[0025] In order to connect the LED component 1 and the heat dissipation component 3, in this embodiment, the connection component 2 includes a bracket 20. One end of the bracket 20 is fixedly connected to the lamp holder 11. A through hole is provided at one end of the bracket 20, and a bolt 21 is threadedly connected at the through hole. One end of the bracket 20 is fixedly connected to the heat dissipation component 3 through the bolt 21. One end of the bracket 20 is fixedly connected to the LED component 1 by welding, and the other end is connected to the heat dissipation component 3 by screws. Keeping a certain distance between the two components helps with heat dissipation.

[0026] In order to dissipate the heat of the LED component 1, in this embodiment, the heat dissipation component 3 includes an outer frame 30. The outer frame 30 is fixedly connected with heat sinks 31. The heat sinks 31 communicate with the outer frame 30. A water outlet is provided at the lower part of one side of the outer frame 30. A water outlet pipe 32 is fixedly connected at the water outlet. The water outlet pipe 32 is fixedly connected with a water pump 33. The other end of the water pump 33 is fixedly connected with the lamp holder 11. An inlet is provided at the upper part of one side of the outer frame 30. An inlet pipe 34 is fixedly connected at the inlet. By the rotation of the water pump 33, the coolant is driven to flow. The coolant enters the lamp holder 11 from the inlet, takes away the heat therein after flowing through the lamp holder 11, and then flows out from the water outlet. Under the continuous heat dissipation of the heat sinks 31, the coolant is cooled down.

[0027] In order to accelerate the cooling of the coolant, in this embodiment, the fan component 4 includes a fan bracket 40. The fan bracket 40 is fixedly connected with the bracket 20. A through hole is provided in the middle part of the fan bracket 40. A motor 41 is fixedly connected at the through hole. The output shaft of the motor 41 penetrates through the fan bracket 40. A fan blade 42 is fixedly connected to the output shaft of the motor 41. When the output shaft of the motor 41 rotates, the fan blade 42 is driven to rotate, thereby accelerating the air flow and accelerating the cooling of the coolant.

[0028] When a LED light emitting diode with a heat dissipation structure in this embodiment is specifically used, when the LED light emitting diode is operating normally, the lamp beads 10 generate heat, and the heat is transferred to the lamp holder 11 through heat conduction. There is a cavity inside the lamp group, and the cavity is filled with coolant. The coolant enters from the lower part of the lamp holder 11 and flows out from the upper part. One end of the bracket 20 is fixedly connected with the LED component 1 by welding, and the other end is connected with the heat dissipation component 3 by screws. Keeping a certain distance between the two components helps with heat dissipation. The flowing-out coolant enters the heat dissipation component 3, and the heat dissipation component 3 cools down the coolant. By the rotation of the water pump 33, the coolant is driven to flow. The coolant enters the lamp holder 11 from the inlet, takes away the heat therein after flowing through the lamp holder 11, and then flows out from the water outlet. Under the continuous heat dissipation of the heat sinks 31, the coolant is cooled down. The fan component 4 assists the heat dissipation component 3 to cool down the coolant. The output shaft of the motor 41 rotates, driving the fan blade 42 to rotate, thereby accelerating the air flow and accelerating the cooling of the coolant, so as to continuously cool down the LED light emitting diode during lighting.
