Description

Technical Field

[0001] The utility model relates to the technical field of LED light source equipment, in particular to an adaptive heat dissipation LED light source. Background Art

[0002] With the continuous advancement of modern lighting technology, LED (Light Emitting Diode) light sources have been widely used in various lighting fields, such as home lighting, commercial lighting, road lighting, and industrial lighting, due to their high efficiency, energy saving, long life, and environmental protection. The popularity of LED light sources has not only greatly improved people's lighting environment but also promoted the transformation and upgrading of the lighting industry. However, with the widespread application of LED light sources, how to effectively manage their operating temperature and ensure their optimal performance under various environmental conditions remains a major challenge.

[0003] Deficiencies of existing technology:

[0004] Currently, traditional LED light source heat dissipation designs mostly use fixed cooling solutions, such as heat sinks and fans. These solutions can effectively reduce the operating temperature of LED light sources to a certain extent, but there is the problem of uncontrollable heat dissipation effect. Especially in low-temperature environments, LED light sources require a certain amount of time to rise to the optimal operating temperature to achieve optimal luminous efficiency and stability. However, traditional heat dissipation solutions often cannot adaptively adjust according to the actual operating temperature of the LED light source. As a result, the heat dissipation efficiency is too high during low-temperature startup, which in turn delays the speed at which the LED light source reaches the optimal operating temperature. This not only affects the immediate lighting effect of the LED light source, but also may accelerate the aging of the LED chip due to prolonged low-temperature operation, shortening its service life.

DETAILED DESCRIPTION

For example, they can refer to fixed connection or disposition, detachable connection or disposition, or integrated connection or disposition.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "several" means two or more, unless otherwise specifically defined. Example

[0031] See also Figure 1-5 As shown, the utility model provides a technical solution for an adaptive heat dissipation LED light source: an adaptive heat dissipation LED light source, comprising an outer shell 1 and an inner shell 2 fixed in the outer shell 1, a heat dissipation seat 3 is provided at the lower ends of the outer shell 1 and the inner shell 2, a light-emitting part 4 is installed at the lower end of the heat dissipation seat 3, a heat dissipation component 5 is installed on the inner side of the outer shell 1 and the upper end of the inner shell 2, an adjustment component 6 for adjusting the heat dissipation efficiency is installed at the lower end of the inner shell 2, a controller 7 is installed on the outer wall of the outer shell 1, and a temperature sensor is built into the light-emitting part 4 to provide real-time temperature data for the controller 7.

[0032] The heat dissipation assembly 5 includes chutes 501, thermal strips 502, and an annular fan 504. The chutes 501 are evenly spaced on the upper end of the inner shell 2. The thermal strips 502 are embedded in the lower end of the inner shell 2 and connected to the heat sink 3. The upper end of the thermal strips 502 is located within the chutes 501 and is rotatably connected to the heat dissipation fins 503. The heat dissipation fins 503 are movably mounted within the corresponding chutes 501. The annular fan 504 is sleeved on the outer wall of the lower end of the inner shell 2 to generate airflow outside the inner shell 2.

[0033] When the light-emitting unit 4 is performing lighting operations, the heat-conducting strips 502 first remove heat from the heat sink 3 and then transfer it to the heat dissipation fins 503 for dissipation. If the operating temperature of the LED light source is low at this time, this state helps to increase the temperature. When the controller 7 detects that the temperature has risen to a certain level through the temperature sensor within the light-emitting unit 4, the annular fan 504 is activated. The annular fan 504 creates an airflow outside the inner shell 2, improving the heat dissipation efficiency of the heat dissipation fins 503 and the surface of the inner shell 2. As the temperature continues to rise, the control adjustment component 6 is activated, and the adjustment component 6 pushes the heat dissipation fins 503 out of the chute 501. At this time, the heat on the heat dissipation fins 503 is removed through the airflow formed by the annular fan 504, further improving the heat dissipation efficiency. Through the heat dissipation component 5, the heat dissipation efficiency of the LED light source is reduced in low-temperature environments and then increased after the temperature rises. This effectively controls the heat dissipation efficiency of the LED light source, allowing it to adapt to operating environments with different temperatures, thereby improving the lighting effect and service life of the LED light source.

[0034] Adjustment assembly 6 includes an electromagnet 601 and a reset cord 604. Electromagnet 601 is fixedly mounted at the lower end of inner housing 2. A push block 602 is movably mounted above electromagnet 601. A permanent magnet 603, matching the electromagnet 601, is mounted at its lower end. The push block 602 moves up and down within inner housing 2 through the interaction of electromagnet 601 and permanent magnet 603. A reset cord 604 is connected between the upper end of push block 602 and the lower end of heat sink fin 503 to retract the heat sink fin 503 into inner housing 2.

[0035] When the controller 7 detects that the temperature has risen to a certain level, the operation of the annular fan 504 alone can no longer meet the heat dissipation requirements of the LED light source. At this point, the electromagnet 601 is energized to generate a certain repulsive force on the permanent magnet 603. This repulsive force causes the pusher 602 to move upward, pushing the heat dissipating fins 503 out of the inner housing 2, overcoming the tension of the reset cord 604. As the temperature of the light-emitting portion 4 increases, the controller 7 controls the current flowing through the electromagnet 601, which in turn increases the repulsive force. This pushes more of the heat dissipating fins 503 out of the chute 501, thereby enhancing the heat conduction effect of the annular fan 504 on the heat dissipating fins 503. When the heat dissipation requirements decrease or the LED light source is turned off, the electromagnet 601 is de-energized, and the heat dissipating fins 503 are reset by the reset cord 604 and retracted into the inner housing 2. Through the adjustment component 6, the heat dissipation performance of the LED light source is dynamically adjusted according to the temperature of the light-emitting portion 4, further optimizing the heat dissipation efficiency of the LED light source and enhancing its adaptability to complex environments.

[0036] Ventilation holes 8 are provided at the ends of the housing 1 on the upper and lower sides of the annular fan 504 . The annular fan 504 drives the air flow to enter from the ventilating holes 8 at the lower end of the housing 1 and to be discharged from the ventilating holes 8 at the upper end.

[0037] A limiting groove 201 is provided on the upper end wall of the inner shell 2, and a positioning column 202 is also centrally installed on the upper end of the inner shell 2. The limiting groove 201 and the positioning column 202 are used to limit the rotation stroke of the heat dissipating fin 503. The positioning column 202 is used to limit the heat dissipating fin 503 when it is retracted, and the limiting groove 201 is used to limit the heat dissipating fin 503 when it is rotated outward.

[0038] The controller 7 is electrically connected to the light emitting part 4 , the annular fan 504 and the electromagnet 601 through wires. The controller 7 controls the current on the annular fan 504 and the electromagnet 601 by receiving the temperature signal from the temperature sensor in the light emitting part 4 .

[0039] The upper end of the push block 602 is rounded, which helps to improve the wear between the heat dissipation fins 503 and the push block 602.

[0040] The working principle of this utility model is as follows:

[0041] In this embodiment of an adaptive heat-dissipating LED light source, when the light-emitting portion 4 is performing lighting operations, the heat-conducting strip 502 first removes heat from the heat sink 3 and then transfers it to the heat-dissipating fins 503 for dissipation. If the operating temperature of the LED light source is relatively low at this time, this state helps to increase the temperature. When the controller 7 detects that the temperature has risen to a certain level through the temperature sensor within the light-emitting portion 4, the annular fan 504 is activated. The annular fan 504 creates an airflow outside the inner shell 2, improving the heat dissipation efficiency of the heat-dissipating fins 503 and the surface of the inner shell 2. As the temperature continues to rise, the controller 7 controls the electromagnet 601 to be energized to generate a certain repulsive force on the permanent magnet 603. Under the action of the repulsive force, the push block 602 moves upward, pushing the heat-dissipating fins 503 out of the inner shell 2, overcoming the tension of the reset pull cord 604. The higher the temperature of the light-emitting portion 4, the greater the current controlled by the controller 7 to flow through the electromagnet 601, the greater the repulsive force, and the greater the portion of the heat-dissipating fin 503 that is pushed out of the chute 501. The annular fan 504 also enhances the heat-dissipating effect on the heat-dissipating fin 503. When the heat dissipation demand decreases or the LED light source is turned off, the electromagnet 601 is also powered off, and the heat dissipation fins 503 are reset under the action of the reset rope 604 and retracted into the inner shell 2.

The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
