[0003] Existing modular LED heat dissipation lamps are usually equipped with effective heat dissipation structures. The existing heat dissipation structures usually require corresponding systems for control, which increases costs. The heat generated by the lamps will also affect the normal operation of the heat dissipation structure. In addition, the existing lamp heat dissipation structures all dissipate heat through heat transfer, which has low efficiency and is not directly connected to the outside world.

A movable cavity is provided in the first connecting rod, and a connecting cavity and a temperature sensing cavity are provided in the temperature sensing column. A second sealing slide is also slidably provided in the temperature sensing column. The temperature sensing cavity is provided at the upper wall of the second sealing slide, and the connecting cavity is provided at the lower wall of the second sealing slide. A connecting plate is fixedly provided between the temperature sensing column and the first connecting rod, and the connecting cavity and the movable cavity are connected to each other through the connecting plate. A first sealing slide is slidably provided in the movable cavity, and the lower ends of the first sealing slide and the second connecting rod are fixed to each other.

[0009] Preferably: a plurality of protective shell plates are evenly fixed on the side wall of the lamp body, the plurality of protective shell plates are fixed to each other with the upper connecting ring, and a guide air plate is fixed to the lower ends of the plurality of protective shell plates, the guide air plate is inclined, and the inclination direction of the guide air plate is set toward the light bulb.

[0010] Preferably, a spring is fixedly provided between the lower wall of the upper connecting ring and the inner bottom wall of the groove, and the spring is provided at the outer sides of the first connecting rod and the second connecting rod.

[0011] Preferably, sealing rubber rings are arranged around the side walls of the first sealing slide plate and the second sealing slide plate, and the sealing rubber rings are bonded to the first sealing slide plate and the second sealing slide plate respectively.

[0013] Preferably, the temperature sensing cavity contains expansion liquid, and the expansion liquid is mercury.

[0014] The present invention provides a modular LED heat dissipation lamp. Compared with the prior art, it has the following beneficial effects:

[0015] (1) In the modular LED heat dissipation lamp, as the LED lamp is running for a longer time, the temperature inside the lamp gradually increases. As the temperature of the lamp body steadily increases, the mercury in the temperature sensing chamber gradually expands through the temperature transmission and sensing of the temperature sensing plate. When the mercury in the temperature sensing chamber expands, it pushes the second sealing slide plate to move downward, and through the connection of the connecting chamber, it drives the first sealing slide plate to move upward in the moving chamber, thereby causing the second connecting rod to move upward, thereby pushing the lamp body and the bulb to separate, so that a gap is generated between the lamp body and the bulb, and the temperature generated in the lamp body is discharged.

[0016] (2) In the modular LED heat dissipation lamp, when the lamp body and the bulb are separated, the temperature of the lamp body increases before the lamp body and the bulb are separated, and the gas in the lamp body expands, causing the air pressure in the lamp body to increase. Therefore, when the lamp body and the bulb are separated, the internal air pressure is released from the gap between the lamp body and the bulb. The guide air plate is provided, so that when the air pressure in the lamp body is discharged, the dust and debris on the surface of the bulb can be removed through the guiding effect of the guide air plate, effectively solving the problem of long-term accumulation of dust on the surface of the bulb affecting the brightness of the bulb. At the same time, the removal of dust effectively solves the problem of reduced heat dissipation efficiency of the bulb caused by dust accumulation, further protecting the safe use of the bulb.

[0017] (3) When the temperature inside the lamp body of the modular LED heat dissipation lamp reaches a certain threshold, the lamp body and the bulb automatically separate to dissipate heat and clean the surface of the bulb. When the temperature is lower than the threshold, the lamp body and the bulb are reassembled together by the action of a spring to prevent external pollution from entering the lamp body and causing adverse effects on the lamp body. This makes the LED lamp achieve a cooling effect similar to breathing, greatly increasing the operating safety of the LED lamp. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0026] See also Figure 1-6 A modular LED heat dissipation lamp comprises a lamp body 1, a connector 2 and a bulb 3. The upper end of the lamp body 1 is fixedly provided with the connector 2, the lower side of the connector 2 is provided with the bulb 3, the lower end of the lamp body 1 is fixedly provided with an upper connecting ring 5, the upper end of the bulb 3 is fixedly provided with a corresponding lower connecting ring 7, the upper wall of the lower connecting ring 7 is fixedly provided with a fixing ring 8, a connecting mechanism is provided between the fixing ring 8 and the upper connecting ring 5, and the connecting mechanism comprises an elastic connecting component and a temperature control component;

[0027] The elastic connection assembly includes a plurality of grooves 9 uniformly arranged on the upper wall of the fixing ring 8, a first connecting rod 10 is fixedly arranged in the lower wall of the groove 9, a second connecting rod 11 is arranged at the upper end of the first connecting rod 10, and the upper end of the second connecting rod 11 and the lower wall of the upper connecting ring 5 are fixed to each other;

[0028] The temperature control component includes a plurality of temperature-sensing columns 14 arranged on the inner wall of the fixed ring 8, and the plurality of temperature-sensing columns 14 correspond to the plurality of first connecting rods 10 one by one. A movable cavity 19 is arranged in the first connecting rod 10, and a connecting cavity 18 and a temperature-sensing cavity 20 are arranged in the temperature-sensing column 14. A second sealing slide plate 17 is also slidably arranged in the temperature-sensing column 14. The temperature-sensing cavity 20 is arranged at the upper wall of the second sealing slide plate 17, and the connecting cavity 18 is arranged at the lower wall of the second sealing slide plate 17. A connecting plate 13 is fixedly arranged between the temperature-sensing column 14 and the first connecting rod 10, and the connecting cavity 18 and the movable cavity 19 are connected to each other through the connecting plate 13. A first sealing slide plate 16 is slidably arranged in the movable cavity 19, and the lower ends of the first sealing slide plate 16 and the second connecting rod 11 are fixed to each other.

[0029] When the temperature inside the lamp body 1 reaches a certain threshold, the lamp body 1 and the bulb 3 are automatically separated to dissipate heat, and the surface of the bulb 3 is cleaned. When the temperature is lower than the threshold, the lamp body 1 and the bulb 3 are recombined together through the action of the spring 12 to prevent external pollution from entering the lamp body 1 and causing adverse effects on the lamp body 1, so that the LED lamp achieves an effect similar to breathing heat dissipation, greatly increasing the operating safety of the LED lamp.

[0030] In an optional embodiment: a plurality of protective shell plates 4 are evenly fixed on the side wall of the lamp body 1, the plurality of protective shell plates 4 are fixed to each other together with the upper connecting ring 5, and a guide air plate 6 is fixed to the lower ends of the plurality of protective shell plates 4, the guide air plate 6 is inclined, and the inclination direction of the guide air plate 6 is set toward the bulb 3.

[0031] It should be noted that after the lamp body 1 and the bulb 3 are separated, the temperature inside the lamp body 1 increases before the lamp body 1 and the bulb 3 are separated, and the gas inside the lamp body 1 expands, causing the air pressure inside the lamp body 1 to increase. As a result, when the lamp body 1 and the bulb 3 are separated, the internal air pressure is released and discharged from the gap between the lamp body 1 and the bulb 3. By setting the guide air plate 6, when the air pressure in the lamp body 1 is discharged, the dust and debris on the surface of the bulb 3 can be cleared through the guiding effect of the guide air plate 6, effectively solving the problem that the brightness of the bulb 3 is affected by the long-term accumulation of dust on the surface of the bulb 3. At the same time, the removal of dust effectively solves the problem that the heat dissipation efficiency of the bulb 3 is reduced due to the accumulation of dust, further protecting the safe use of the bulb 3.

[0032] In an optional embodiment, a spring 12 is fixedly provided between the lower wall of the upper connecting ring 5 and the inner bottom wall of the groove 9 , and the spring 12 is provided at the outer sides of the first connecting rod 10 and the second connecting rod 11 .

[0033] It should be noted that the degree of mercury expansion when the temperature inside the lamp body 1 reaches a certain degree can be controlled by adjusting the stiffness coefficient of the spring 12, that is, the force pushing the first sealing slide 16 to move. When it exceeds the elastic force of the spring 12, the lamp body 1 and the bulb 3 can overcome the elastic force of the spring 12 and separate to dissipate heat. This process can be carried out through a limited number of experiments to adjust the stiffness coefficient of the spring 12 according to needs, thereby adjusting the temperature threshold for heat dissipation in the lamp body 1.

[0034] In an optional embodiment: sealing rubber rings are arranged around the side walls of the first sealing slide plate 16 and the second sealing slide plate 17 , and the sealing rubber rings are bonded to the first sealing slide plate 16 and the second sealing slide plate 17 , respectively.

[0035] It should be noted that when the first sealing slide plate 16 and the second sealing slide plate 17 move, a gap between the side wall and the inside of the cavity is effectively prevented, resulting in mercury leakage or gas leakage, thereby ensuring the safety of the device.

[0036] In an optional embodiment: a temperature sensing plate 15 is provided at the upper side wall of the temperature sensing column 14 , the temperature sensing plate 15 is at the side wall of the temperature sensing cavity 20 , and the temperature sensing plate 15 is arranged toward the inside of the lamp body 1 .

[0037] It should be noted that as the temperature in the lamp body 1 rises steadily, the mercury in the temperature sensing cavity 20 gradually expands through the temperature transfer and sensing of the temperature sensing plate 15 . When the mercury in the temperature sensing cavity 20 expands, it pushes the second sealing slide plate 17 to move downward.

[0038] In an optional embodiment, the temperature sensing chamber 20 contains an expansion liquid, which is mercury.

[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] During the operation of the LED lamp, as the operation time of the LED lamp increases, the temperature inside the LED lamp gradually increases. As the temperature in the lamp body 1 steadily increases, the mercury in the temperature sensing cavity 20 gradually expands through the temperature transmission and sensing of the temperature sensing plate 15. When the mercury in the temperature sensing cavity 20 expands, the second sealing slide plate 17 is pushed to move downward, and the first sealing slide plate 16 is driven to move upward in the moving cavity 19 through the connection of the connecting cavity 18, so that the second connecting rod 11 moves upward, thereby pushing the lamp body 1 and the bulb 3 to separate, so that a gap is generated between the lamp body 1 and the bulb 3, and the temperature generated in the lamp body 1 is discharged;

[0041] In the above process, the degree of mercury expansion can be controlled by adjusting the stiffness coefficient of the spring 12 when the temperature in the lamp body 1 reaches a certain degree, that is, the force of pushing the first sealing slide plate 16 to move exceeds the elastic force of the spring 12, and the lamp body 1 and the bulb 3 can overcome the elastic force of the spring 12 to separate, thereby dissipating heat. This process can be carried out through a limited number of experiments to adjust the stiffness coefficient of the spring 12 according to needs, thereby adjusting the temperature threshold for heat dissipation in the lamp body 1;

[0042] At the same time, in the above process, after the lamp body 1 and the bulb 3 are separated, the temperature inside the lamp body 1 increases before the lamp body 1 and the bulb 3 are separated, and the gas inside the lamp body 1 expands, so that the air pressure inside the lamp body 1 increases. Therefore, when the lamp body 1 and the bulb 3 are separated, the internal air pressure is released and discharged from the gap between the lamp body 1 and the bulb 3. The guide air plate 6 is provided, so that when the air pressure in the lamp body 1 is discharged, the dust and sundries on the surface of the bulb 3 are removed through the guiding effect of the guide air plate 6, which effectively solves the problem of long-term accumulation of dust on the surface of the bulb 3 affecting the brightness of the bulb 3. At the same time, the removal of dust effectively solves the problem of reduced heat dissipation efficiency of the bulb 3 caused by dust accumulation, and further protects the safe use of the bulb 3.

[0043] Through the above process, when the temperature in the lamp body 1 reaches a certain threshold, the lamp body 1 and the bulb 3 are automatically separated to dissipate heat, and the surface of the bulb 3 is cleaned. When the temperature is lower than the threshold, the lamp body 1 and the bulb 3 are recombined together through the action of the spring 12 to prevent external pollution from entering the lamp body 1 and having an adverse effect on the lamp body 1, so that the LED lamp achieves an effect similar to breathing heat dissipation, which greatly increases the operating safety of the LED lamp.
