Description

Technical Field

[0001] The invention relates to the technical field of LED lamps, and in particular to an LED glass lamp cup with a high-efficiency heat dissipation structure. Background Art

[0002] LED lamps have the characteristics of high luminous efficiency and low power consumption, and are deeply loved by people. However, due to the low power and brightness of a single LED lamp, it is not suitable to be used alone. Instead, multiple LED lamps are assembled together to design a more practical LED lighting fixture. However, the combination of multiple LED lamps will generate a lot of heat. If the heat cannot be transferred and dissipated in time, it will easily lead to light decay and affect the service life of the LED lighting fixture.

[0003] For example, in the prior art, there is a breathable heat dissipation device for an LED bulb and a breathable heat dissipation LED bulb with publication number CN102384451A. The interior of the LED lamp is directly connected to the outside, and the heat generated inside the bulb causes natural convection of the internal and external air. Although it can achieve a certain heat dissipation effect, the air circulation rate is slow by natural convection, and it is difficult to quickly take away the heat in the bulb. In addition, dust and impurities from the outside are easy to enter the interior of the bulb, which greatly affects the brightness and life of the LED bulb.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an LED glass lamp cup with an efficient heat dissipation structure. The structure is to drive the drainage component to run intermittently in forward and reverse directions, and autonomously adjust the blowing direction. The upper air inlet and the lower air inlet are combined to alternately extract external cold air to change the flow direction of the cold air, take away the heat transferred to the heat dissipation fins, and achieve the effect of efficient heat dissipation. The hot air is discharged to back-blow the annular filter, which in turn causes the wind wheel to carry the cleaning brush to rotate, and the annular filter is cleaned for the second time, thereby achieving an efficient self-cleaning effect on the annular filter.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) When the LED glass lamp cup of the present invention is working, first, the temperature of the aluminum substrate is collected through the temperature sensor, and the collected data is transmitted to the control module.

[0017] Secondly, by means of the alternating change of the airflow direction inside the lamp cup, it can effectively avoid the problem that when the cold air flows in one direction for a long time, the heating is completed in the front section of the path, which reduces the heat absorption effect on the rear section of the path, and then the rear section of the one-way flow path cannot be cooled quickly, making it difficult to achieve comprehensive and efficient cooling treatment;

[0018] In addition, when the silent motor in the drainage component is controlled to rotate forward and reverse, the deflection angle of the fan blades can be automatically adjusted, thereby autonomously adjusting the upward or downward blowing, and maintaining the air flow rate during the rotation of the fan blades to the greatest extent, thereby achieving efficient operation of the drainage component;

[0019] (2) The present invention can effectively prevent external dust and impurities from entering the lamp cup with the air when the upper air inlet and the lower air inlet alternately draw in external cold air. It can also back-blow and clean the annular filter by means of the discharge of heated cold air. In combination with the oblique opening of the air inlet, the wind wheel carrying the cleaning brush is driven to rotate to clean the annular filter, thereby achieving an efficient self-cleaning effect of the annular filter, thereby avoiding the problem of clogging of the annular filter mesh after long-term use, which leads to a decrease in the gas flow rate inside the lamp cup and a decrease in the heat dissipation effect.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 1-Figure 9 As shown, in the prior art, the air circulation rate is slow and it is difficult to quickly take away the heat in the bulb, resulting in poor heat dissipation effect. The following solution can be used to solve the problem;

[0039] The LED glass lamp cup with an efficient heat dissipation structure in this embodiment includes an aluminum cup 1, and an aluminum base column 2 fixedly connected to the top of the aluminum cup 1 and connected thereto, an insulating sleeve fixedly connected to the top of the aluminum base column 2, a screw joint electrically connected to a circuit board is installed on the insulating sleeve, the screw joint on the aluminum base column 2 is installed on the lamp holder, the circuit board is powered on, the LED lamp bead 31 emits light and generates heat, and the generated heat is transferred to the aluminum substrate 3, the aluminum cup 1 and the aluminum base column 2;

[0040] The aluminum cup 1 and the aluminum base column 2 are respectively fixedly connected with a heat dissipation fin 11 and a heat dissipation fin 21 on the annular outer wall. By installing a plurality of heat dissipation fins 11 on the outer wall of the aluminum cup 1, the contact area between the cold air flow caused by forced convection and the aluminum cup 1 can be increased, thereby improving the heat transfer efficiency and the heat dissipation effect.

[0041] A plurality of heat dissipation fins 21 are installed on the outer wall of the aluminum base column 2 to increase its contact area with the outside air. Since the aluminum base column 2 absorbs the heat from the aluminum substrate 3 and the aluminum cup 1 at intervals, it contains less heat and can complete the heat dissipation process by naturally contacting the outside air, which can further assist the heat dissipation efficiency of the aluminum substrate 3 and the aluminum cup 1, and achieve a high-efficiency heat dissipation effect.

[0042] A glass shell 12 is provided on the outside of the aluminum cup 1. The glass shell 12 prevents external dust from falling onto the heat dissipation fin 11, thereby affecting the heat transfer efficiency between the cold air and the heat dissipation fin 11, and at the same time increases the aesthetics of the LED glass lamp cup. An aluminum base plate 3 is installed inside the aluminum cup 1 by screws, and a plurality of LED lamp beads 31 are fixedly installed on the bottom of the aluminum base plate 3, and a heat dissipation fin 3 32 is fixedly connected to the top of the aluminum base plate 3.

[0043] The heat dissipation fin three 32 is provided with a concave and convex surface, which is used to further increase the effect of driving the heat on the aluminum substrate 3 during the flow of cold air inside the lamp cup. After the aluminum substrate 3 is connected to the aluminum cup 1 by screws, the top of the heat dissipation fin three 32 and the annular side of the aluminum substrate 3 are in contact with the aluminum cup 1, thereby increasing the heat transfer effect between the aluminum substrate 3 and the aluminum cup 1.

[0044] The interior of the aluminum base column 2 is provided with a drainage component 4 with self-adjustable wind direction. The drainage component 4 includes a mounting frame 41 fixedly connected to the bottom of the aluminum base column 2. A rotating wheel 42 is installed on the top of the mounting frame 41, and a plurality of fan blades 43 are evenly installed on the outer wall of the rotating wheel 42. The rotating wheel 42 drives the plurality of fan blades 43 to rotate inside the aluminum base column 2, and the external cold air is extracted and discharged in combination with the air inlet, causing forced drainage of the gas inside the lamp cup, increasing the air circulation rate, and quickly taking away the heat in the lamp cup to achieve efficient heat dissipation effect. A circuit board is installed on the bottom screw of the mounting frame 41, and a control module is installed on the circuit board;

[0045] A temperature sensor for monitoring the temperature of the aluminum substrate 3 is installed at the bottom of the mounting frame 41. The temperature sensor collects data on the temperature of the aluminum substrate 3 and transmits the collected data to the control module. The control module compares and analyzes the collected data. When the collected data is greater than the preset data, the control module generates a control signal to start the rotation of the fan blades 43 to cool down and dissipate heat from the aluminum substrate 3, the aluminum cup 1 and the aluminum base column 2. Otherwise, the control module does not generate a control signal to start the rotation of the fan blades 43 to avoid unnecessary energy waste.

[0046] An annular groove 22 is provided on the outer wall of the aluminum base column 2, and a semicircular snap ring 23 is symmetrically embedded and installed in the annular groove 22. The semicircular snap ring 23 is fixedly connected to the aluminum base column 2 by screws. The bottom of the aluminum cup 1 is threadedly connected with a glass lampshade 13. The diameter of the aluminum base column 2 is smaller than the opening diameter of the top of the glass shell 12, which is convenient for disassembly and installation of the glass shell 12, and further convenient for cleaning the trace small dust particles on the heat dissipation fin 11 that have been screened by the filter, and the dust on the glass shell 12;

[0047] The outer diameter of the two sets of semicircular snap rings 23 is larger than the opening diameter at the top of the glass shell 12. After the glass shell 12 is sleeved on the outside of the aluminum cup 1, the two sets of semicircular snap rings 23 are embedded in the annular groove 22 and fixed by screws. The bottom of the installed semicircular snap rings 23 restricts the separation of the glass shell 12 from the aluminum cup 1. The glass lampshade 13 is threadedly connected to the aluminum cup 1, and the aluminum base plate 3 is in contact with the side wall of the aluminum cup 1, which can effectively prevent external dust from entering the interior of the aluminum cup 1 below the aluminum base plate 3, thereby avoiding the problem of reducing the lighting effect.

[0048] A connecting port 14 is provided on the inner wall of the aluminum cup 1 between two adjacent heat dissipation fins 11 to facilitate the mutual circulation between the air inside the aluminum cup 1 above the aluminum substrate 3 and the air outside the aluminum cup 1. A wind shield ring 15 that contacts the glass shell 12 is fixedly connected on the outer wall of the aluminum cup 1 and below the heat dissipation fins 11, and a plurality of lower air inlets 16 equidistantly distributed and obliquely arranged are provided on the top of the wind shield ring 15. The arranged wind shield ring 15 and the lower air inlet 16 opened on the wind shield ring 15 prevent the gas between the aluminum cup 1 and the glass shell 12 from being discharged over a large area, and perform guided and designated discharge.

[0049] An annular groove 24 is provided on the annular outer wall of the aluminum base column 2, and a plurality of upper air inlets 25 connected to the annular groove 24 are provided on the annular inner wall of the aluminum base column 2, and the upper air inlets 25 are provided at an angle;

[0050] The heat on the aluminum substrate 3 is transferred to the multiple heat dissipation fins 32, and the heat on the aluminum cup 1 is transferred to the multiple heat dissipation fins 11. When the temperature of the aluminum substrate 3 is higher than the preset temperature, the rotating wheel 42 carries the fan blades 43 to rotate forward, blow air downward, and draws external cold air into the aluminum base column 2 through the upper air inlet 25, and then discharges it into the aluminum cup 1 above the aluminum substrate 3, taking away the heat on the heat dissipation fins 32, and then enters between the aluminum cup 1 and the glass shell 12 through the multiple connecting ports 14 on the aluminum cup 1, taking away the heat on the heat dissipation fins 11, and finally discharges it through the multiple lower air inlets 16 on the wind shield ring 15, performing efficient heat dissipation treatment, until the temperature of the aluminum substrate 3 drops below the preset temperature, and the rotation of the fan blades 43 is stopped;

[0051] After the temperature of the aluminum substrate 3 rises again, the rotating wheel 42 carries the fan blades 43 to rotate in the opposite direction, blows air upward, extracts the air in the aluminum cup 1 to form a negative pressure environment, and extracts the external cold air into the aluminum cup 1 through the connecting port 14 and the lower air inlet 16, and takes away the heat on the heat dissipation fins 11 and 32 in turn, and then discharges it through the multiple upper air inlets 25 on the aluminum base column 2, performing efficient heat dissipation processing until the temperature of the aluminum substrate 3 drops again;

[0052] Each time the drainage component 4 stops and then restarts, the rotating wheel 42 changes its rotation direction, and draws and discharges external cold air alternately through the upper air inlet 25 and the lower air inlet 16 to take away the heat transferred from the heat dissipation fins, so as to achieve the effect of efficient heat dissipation. With the help of the alternating change of the internal airflow flow direction, it can effectively avoid the cold air from heating up in the front section of the path when it flows in one direction for a long time, reducing the heat absorption effect on the rear section of the path, which in turn leads to the problem that the rear section of the unidirectional flow path cannot be cooled quickly, making it difficult to achieve comprehensive and efficient cooling treatment.

[0053] The top bolts in the aluminum base column 2 are installed with a silent motor 45 for driving the rotating wheel 42 to rotate, so as to avoid noise during the cooling process and cause discomfort in use. The fan blade 43 is fixedly connected with a rotating sleeve 47 through a rotating shaft 46, and the rotating wheel 42 is provided with a rotating groove 48 adapted to the corresponding rotating sleeve 47. By setting the rotating sleeve 47 and the rotating groove 48, when the silent motor 45 is controlled to rotate forward and reverse, the deflection angle of the fan blade 43 can be automatically adjusted, and the upward or downward blowing can be independently adjusted, thereby maintaining the air flow rate during the rotation of the fan blade 43 to the greatest extent, and realizing the efficient operation efficiency of the drainage component 4.

[0054] The output shaft of the silent motor 45 movably penetrates the interior of the rotating wheel 42 and is fixedly connected to a bevel gear 1 49, a bevel gear 2 410 meshing with the bevel gear 1 49 is fixedly connected to the rotating shaft 46, a limiting groove 411 is provided on the annular outer wall of the rotating sleeve 47, a limiting block 412 slidably connected to the limiting groove 411 is fixedly installed on the rotating groove 48, and a damping shaft 413 rotatably connected to the rotating wheel 42 is fixedly connected to the top of the mounting frame 41;

[0055] The control module controls the silent motor 45 to rotate forward. Under the rotation damping action of the damping shaft 413, the rotating wheel 42 is first restricted from following the rotation. The output shaft of the silent motor 45 drives the bevel gear 1 49 to rotate. The bevel gear 1 49 drives the multiple rotating shafts 46 to rotate through the meshing bevel gear 2 410. Then, the limiting groove 411 on the rotating sleeve 47 contacts the limiting block 412 to restrict the continued rotation of the rotating shaft 46. At this time, the angle adjustment of the fan blade 43 blowing air downward is completed. Then, with the help of the limiting groove 411 and the limiting block 412, the silent motor 45 drives the rotating wheel 42 to overcome the rotation damping action force of the damping shaft 413, and carries the fan blade 43 to rotate forward.

[0056] When the control module controls the silent motor 45 to start for the second time, the silent motor 45 rotates in the reverse direction, and combined with the damping shaft 413, the meshing bevel gear 1 49 and the bevel gear 2 410 drive the multiple rotating shafts 46 to rotate in the reverse direction, and the other side of the upper limit groove 411 of the rotating sleeve 47 contacts the limit block 412, thereby limiting the further reversal of the rotating shaft 46, completing the angle adjustment of the fan blades 43 blowing air upward, and then prompting the silent motor 45 to drive the rotating wheel 42 to carry the fan blades 43 to rotate in the reverse direction.

[0057] Example 2: Please refer to Figure 2-Figure 5 , Fig.10 and Fig.11 As shown, the following solutions can be used to solve the problem of external dust and impurities entering the LED glass lamp cup by using forced convection, which affects the service life;

[0058] In this embodiment, the bottom of the wind shield ring 15 is fixedly connected with an annular filter 17. When the outside cold air is drawn into the space between the aluminum cup 1 and the glass shell 12 through the lower air inlet 16, the dust and impurities in the air are blocked by the annular filter 17. The bottom of the outer wall of the aluminum cup 1 is rotatably connected with a lower wind wheel 18, and the top of the lower wind wheel 18 is fixedly connected with a plurality of cleaning brushes 19 in contact with the annular filter 17. The annular outer wall of the lower wind wheel 18 is fixedly connected with an air blocking ring that slides with the glass shell 12.

[0059] When the air that absorbs heat is discharged, it is discharged obliquely through the oblique opening of the lower air inlet 16 and pushes the lower wind wheel 18 to rotate. The lower wind wheel 18 carries multiple cleaning brushes 19 to rotate to clean the dust and impurities filtered on the annular filter 17, and back-blows the discharged air to efficiently self-clean the annular filter 17.

[0060] A second annular filter screen 26 is fixedly connected to the annular side wall of the annular groove 24. When the external cold air is drawn into the interior of the aluminum base column 2 through the upper air inlet 25, the dust impurities in the air are blocked by the second annular filter screen 26. An upper wind wheel 27 is rotatably connected in the annular groove 24, and a plurality of cleaning brushes 28 in contact with the second annular filter screen 26 are fixedly connected to the annular inner wall of the upper wind wheel 27.

[0061] When the air that absorbs heat is discharged, it is discharged through the upper air inlet 25 opened obliquely, which pushes the upper wind wheel 27 to rotate. The upper wind wheel 27 carries multiple cleaning brushes 28 to rotate to clean the dust and impurities filtered on the annular filter 26, and back-blows the discharged air to effectively self-clean the annular filter 26, so that while the external cold air is alternately drawn in through the upper air inlet 25 and the lower air inlet 16, the self-cleaning of the annular filter is simultaneously realized to avoid the problem of clogging of the annular filter mesh after long-term use, which leads to a decrease in the gas flow rate inside the lamp cup, resulting in a decrease in the heat dissipation effect.

[0062] Example 3: Please refer to Figure 1-Figure 11 As shown, the present invention also provides a method for using an LED glass lamp cup with an efficient heat dissipation structure, comprising the following steps:

[0063] Step 1: Install the screw joint on the aluminum base column 2 on the lamp holder, power on the circuit board, and the LED lamp bead 31 emits light and generates heat, and the generated heat is transferred to the aluminum substrate 3, the aluminum cup 1 and the aluminum base column 2. The temperature of the aluminum substrate 3 is collected by the temperature sensor installed on the mounting frame 41, and the collected data is transferred to the control module. The control module compares and analyzes the collected data. When the collected data is greater than the preset data, the control module starts the drainage component 4 to cool down the aluminum substrate 3, the aluminum cup 1 and the aluminum base column 2. Otherwise, the control module does not generate a control signal to start the fan blade 43 to rotate;

[0064] Step 2: The heat on the aluminum substrate 3 is transferred to the multiple heat dissipation fins 3 32, the heat on the aluminum cup 1 is transferred to the multiple heat dissipation fins 11, and the heat on the aluminum base column 2 is transferred to the multiple heat dissipation fins 21. The control module controls the silent motor 45 to rotate forward, and the output shaft of the silent motor 45 drives the bevel gear 1 49 to rotate. The bevel gear 1 49 drives the multiple rotating shafts 46 to rotate through the meshing bevel gear 2 410, and then the one side of the limit groove 411 on the rotating sleeve 47 contacts the limit block 412 to limit the continued rotation of the rotating shaft 46. At this time, the angle adjustment of the fan blade 43 blowing air downward is completed, and then the limit groove 411 and the limit block 412 are used to prompt the silent motor 45 to drive the rotating wheel 42 to carry the fan blade 43 to rotate forward;

[0065] Step 3: utilize the positive rotation of the fan blades 43 to draw the external cold air into the interior of the aluminum base column 2 through the upper air inlet 25, and block the dust and impurities in the air through the annular filter screen 26, and then discharge it into the aluminum cup 1 above the aluminum base plate 3, take away the heat on the heat dissipation fins 3 32, and then enter between the aluminum cup 1 and the glass shell 12 through the plurality of connecting ports 14 on the aluminum cup 1, take away the heat on the heat dissipation fins 11, and finally discharge it through the plurality of lower air inlets 16 on the wind shield ring 15, and perform efficient heat dissipation treatment. When the air with heat is discharged, it is obliquely opened through the lower air inlet 16, obliquely discharged and drives the lower wind wheel 18 to rotate. The lower wind wheel 18 carries a plurality of cleaning brushes 19 to rotate to clean the dust and impurities filtered on the annular filter screen 17, and back-blows in combination with the discharged air to perform efficient self-cleaning of the annular filter screen 17;

[0066] Step 4: When the control module controls the silent motor 45 to start for the second time, the silent motor 45 rotates in the reverse direction, and drives the multiple rotating shafts 46 to rotate in the reverse direction through the meshing bevel gear 1 49 and the bevel gear 2 410, and the other side of the upper limit groove 411 of the rotating sleeve 47 contacts the limit block 412, so as to limit the further reversal of the rotating shaft 46, and complete the adjustment of the angle of the fan blades 43 blowing upward, and then the silent motor 45 drives the rotating wheel 42 to carry the fan blades 43 to rotate in the reverse direction;

[0067] Step 5: utilize the reverse rotation of the fan blades 43 to extract the air in the aluminum cup 1 to form a negative pressure environment, and extract the external cold air into the aluminum cup 1 through the connecting port 14 and the lower air inlet 16, and take away the heat on the heat dissipation fins 11 and the heat dissipation fins 32 in turn, and block the dust and impurities in the air through the annular filter 17, and then discharge it through the multiple upper air inlets 25 on the aluminum base column 2 for efficient heat dissipation treatment. Combined with the oblique opening of the upper air inlet 25, the blown wind drives the upper wind wheel 27 to rotate, and the upper wind wheel 27 carries multiple cleaning brushes 28 to rotate to clean the dust and impurities filtered on the annular filter 26, and combines with the discharged air to perform backblowing to perform efficient self-cleaning on the annular filter 26.
