Description

Technical Field

[0001] The invention relates to the technical field of lighting work lamps, and in particular to an automatic cooling and dust-proof LED work lamp. Background Art

[0002] As a professional lighting fixture, high-top work lights are widely used. Considering the application site and use environment, the protection requirements for high-top work lights are different. The lampshade of traditional work lights is usually equipped with heat dissipation fins, which can improve the heat dissipation performance of the work light by increasing the effective heat dissipation area. In some high-dust occasions, dust will gradually accumulate on the lampshade of the work light, which makes the lampshade of the work light equivalent to adding a layer of "insulation layer". The heat dissipation performance of the work light will continue to decline with the accumulation of dust, thus affecting normal work.

[0003] Currently, there is a work lamp 10 with a cooling fan on the market, such as Figure 1 As shown. When working, the cooling fan will blow air toward the cooling fins of the lampshade 11, which will promote air flow and improve its cooling performance on the one hand, and blow away the dust that has fallen on the cooling fins on the other hand. However, when the ambient humidity is high, the falling dust will stick to the cooling fins, and the adhesion of the dust will increase, resulting in the inability of the existing cooling fan to blow it away, which will still reduce the cooling performance of the work lamp.

[0004] Therefore, how to design an automatic cooling and dust-proof LED work light so that it can reduce the dust accumulated on the work light during the non-working stage and more effectively remove the dust on the work light during working, thereby achieving cooling and improving the heat dissipation performance, is a technical problem that technicians in this field need to solve.

[0034] The present invention provides an automatic cooling and dust-proof LED work lamp 20, which aims to reduce dust accumulation on the work lamp during non-working stages, and more effectively remove dust on the work lamp during working stages, thereby improving cooling and heat dissipation effects.

[0035] like Figure 2 and Figure 3 As shown, the automatic cooling and dustproof LED work lamp 20 comprises: a lampshade main housing 100, a lamp body part 200, an active heat dissipation part 300 and a dustproof part 400. The lamp body part 200 and the active heat dissipation part 300 are both arranged on the lampshade main housing 100, and the dustproof part 400 is located above the lampshade main housing 100.

[0036] Among them, Figure 3 As shown, a plurality of heat dissipation fins 110 are disposed on the main housing 100 of the lampshade. Preferably, the plurality of heat dissipation fins 110 are distributed in a radial array with the DC fan 310 as the center, and an air duct is formed between two adjacent heat dissipation fins 110.

[0037] like Figure 4 As shown, the active heat dissipation component 300 includes a DC fan 310 and a fan seat 320. The fan seat 320 is arranged on the main housing 100 of the lampshade. The DC fan 310 rotates inside the fan seat 320. When working, the DC fan 310 blows air toward the main housing 100 of the lampshade.

[0038] like Figure 4 As shown, the dustproof component 400 includes: a fixed cover 410, a movable cover 420 and a driving assembly 430. The fixed cover 410 is provided with air holes 411, and the movable cover 420 is connected to the fixed cover 410 through the driving assembly 430, and the driving assembly 430 drives the movable cover 420 to move up and down relative to the fixed cover 410. When rising, the movable cover 420 is away from the main housing 100 of the lampshade; when descending, the movable cover 420 is close to the main housing 100 of the lampshade, and the movable cover 420 cooperates with the fixed cover 410 to form a complete cover body, and an exhaust gap 401 is formed between the movable cover 420 and the main housing 100 of the lampshade.

[0039] In this embodiment, if Figure 5 As shown, the driving assembly 430 includes: a base 431, a tilting rod 432 and a sliding sleeve 433. The base 431 is fixedly installed on the outer side of the fan base 320, and a receiving chamber 4311 and a telescopic push rod 4312 are provided on the base 431. The telescopic push rod 4312 is slidably arranged in the receiving chamber 4311, and a temperature expansion and contraction agent is provided in the receiving chamber 4311. The temperature expansion and contraction agent will expand as the temperature rises and contract as the temperature decreases. The temperature expansion and contraction agent can be a solid or liquid with obvious thermal expansion and contraction properties such as paraffin and alcohol.

[0040] The rotating shaft 4321 of the tilting rod 432 is disposed on the main housing 100 of the lamp shade, and the tilting rod 432 is divided into a short rod end 4322 and a long rod end 4323 with the rotating shaft 4321 as the boundary. The telescopic push rod 4312 is supported on the short rod end 4322 of the tilting rod 432, and the sliding sleeve 433 is disposed on the long rod end 4323 of the tilting rod 432, and the end of the sliding sleeve 433 is hinged to the inner wall of the movable cover 420.

[0041] Preferably, Figure 4 As shown, the fixed cover 410 is a hollow cone structure, and the design of the cone structure can reduce dust accumulation.

[0042] In combination with the above structure, the dustproof working principle of the dustproof component 400 of the present invention is explained below. Please refer to Figure 6 and Figure 7 As shown:

[0043] When not in operation, the lamp body 200 is not turned on, and the temperature of the lampshade main shell 100 is relatively low (normal temperature). In this case, the temperature expansion and contraction agent in the accommodating cavity 4311 is in a contracted state, that is, its volume is relatively small. At this time, the telescopic push rod 4312 is contracted in the accommodating cavity 4311, the tilting rod 432 is tilted, and the movable cover 420 drops to the lowest position under the action of gravity. At this time, the movable cover 420 cooperates with the fixed cover 410 to form a complete cover body, which is covered on the lampshade main shell 100 and completely covers the heat dissipation fin 110 area to prevent dust from falling on the heat dissipation fin 110 area. At the same time, an exhaust gap 401 is formed between the movable cover 420 and the edge of the lampshade main shell 100;

[0044] During operation, when the main part 200 of the lamp is initially turned on, the main part 200 of the lamp begins to heat up and its heat has not yet been transferred to the base 431. At this time, the movable cover 420 is still at the lowest position. The DC fan 310 is started and causes the air around it to flow. The airflow enters the fixed cover 410 through the air hole 411, passes through the air duct between the heat dissipation fins 110, and is finally blown out through the exhaust gap 401. During this period, the dust originally on the main housing 100 of the lampshade will be blown out from the exhaust gap 401 driven by the airflow, thereby powerfully achieving dust cleaning;

[0045] After the main part 200 of the lamp is turned on for a period of time, the heat of the main part 200 of the lamp is transferred to the base 431, and the temperature expansion agent in the accommodating cavity 4311 will absorb heat and expand, thereby pushing out the telescopic push rod 4312. The telescopic push rod 4312 will abut against the short rod end 4322 of the tilting rod 432, and drive the tilting rod 432 to deflect around the rotation axis 4321. At this time, the tilting rod 432 lifts the movable cover 420, so that the movable cover 420 is away from the lampshade main shell 100, which is equivalent to the cover body formed by the movable cover 420 and the fixed cover 410 being opened. At this time, the heat dissipation fin 110 area of ​​the main part 200 of the lamp is completely exposed, and the airflow blowing to the heat dissipation fin 110 can be directly blown out from the four sides of the lampshade main shell 100, so that the heat of the heat dissipation fin 110 can be quickly dissipated into the air, thereby achieving efficient heat dissipation;

[0046] After the lamp body 200 is closed, the heat of the lampshade main housing 100 and the base 431 gradually decreases, the temperature expansion agent slowly shrinks, the telescopic push rod 4312 gradually retracts into the accommodating cavity 4311, and the tilting rod 432 and the movable cover 420 are reset under the action of gravity. The movable cover 420 cooperates with the fixed cover 410 again to form a complete cover body to cover the heat dissipation fin 110 area.

[0047] Compared with the prior art, the automatic cooling and dust-proof LED work light 20 of the present invention can autonomously perform adaptive adjustment through the dust-proof component 400 to achieve the purpose of effective dust removal and rapid heat dissipation. Specifically, when not working, the movable cover 420 and the fixed cover 410 jointly shield the heat dissipation fin 110 area to prevent dust accumulation; in the initial stage of operation, the airflow blows out from the exhaust gap 401, and then can forcefully blow up the dust accumulated on the heat dissipation fin 110 and discharge the dust; in the stable working stage, the movable cover 420 is lifted, and the heat dissipation fin 110 area is no longer shielded, and it can quickly dissipate heat under the blowing of the airflow to achieve efficient heat dissipation. It can be seen that the present invention utilizes the thermal expansion and contraction principle of the temperature expansion and contraction agent to enable the dust-proof component 400 to have the ability to adjust autonomously, so that the LED work light 20 has multiple functions such as dust prevention, dust removal, and rapid heat dissipation, and the multiple functions will not interfere with each other.

[0048] It is worth emphasizing that, when the existing work lamp is not working, the cooling fan is not turned on, and the falling dust will accumulate on the cooling fins; especially when the ambient humidity is high, the adhesion of the dust is enhanced, and it will stick firmly to the cooling fins, resulting in the inability of the existing cooling fan to blow it away. In the present invention, when it is not working, the cooling fin 110 area is shielded, thereby reducing dust accumulation; and at the beginning of work, the airflow can only be blown out through the exhaust gap 401. Since the exhaust gap 401 is small at this time, a high-speed airflow can be formed, so that the sticky dust can be blown away more effectively, achieving a dust cleaning effect.

[0049] Moreover, the tilting rod 432 utilizes the principle of lever, and the telescopic push rod 4312 only needs to move a short distance to cause the movable cover 420 to rise and fall significantly. Moreover, a buffer elastic member 434 is provided between the sliding sleeve 433 and the long rod end 4323 of the tilting rod 432, and the buffer elastic member 434 is a spring structure. The cooperation between the sliding sleeve 433 and the tilting rod 432 provides the necessary telescopic movement space for the sliding sleeve 433 and the movable cover 420 to be hinged in an arc motion. The buffer elastic member 434 can provide a buffer for the telescopic movement of the sliding sleeve 433 to avoid direct collision between the sliding sleeve 433 and the tilting rod 432. At the same time, the buffer elastic member 434 always provides elastic support force for the sliding sleeve 433 and the movable cover 420, which enables the movable cover 420 to rise and fall smoothly, and does not cause excessive deviation to cause the movable cover 420 to get stuck.

[0050] In this embodiment, if Figure 4As shown, the main body part 200 of the lamp includes: an LED light-emitting board 210, a glass lens 220 and a ferrule 230. The LED light-emitting board 210 is arranged in the main housing 100 of the lampshade, and the glass lens 220 is arranged on the main housing 100 of the lampshade through the ferrule 230. A sealing ring (not shown) is arranged between the glass lens 220 and the main housing 100 of the lampshade. When working, the LED light-emitting board 210 emits light and heat, and the light is radiated out through the glass lens 220, and the heat is transferred to the main housing 100 of the lampshade, and dissipated into the air with the help of the heat dissipation fins 110. The arrangement of the ferrule 230 and the sealing ring seals the gap between the glass lens 220 and the main housing 100 of the lampshade, thereby achieving a waterproof and dustproof effect.

[0051] In this embodiment, if Figure 4 As shown, the active heat dissipation component 300 also includes a fan cover 330 and a power supply assembly 340. The fan cover 330 is installed on the fan seat 320. The power supply assembly 340 is accommodated in the fan cover 330, and the power supply assembly 340 is electrically connected to the DC fan 310. Preferably, the fixed cover 420 is installed on the fan cover 330, and the power supply assembly 340 includes a power connection wire 341, which passes through the fan cover 330 and the fixed cover 420. The power supply assembly 340 is connected to an external power source through the power connection wire 341 and supplies power to the DC fan 310.

[0052] Preferably, Figure 4 As shown, a hook 422 is provided on the fixed cover 420. The hook 422 is connected to the fixed cover 420 by threads, so that when needed, the staff can hang the automatic cooling and dust-proof LED work lamp 20 through the hook 422; when not needed, the hook 422 can be disassembled to facilitate the automatic cooling and dust-proof LED work lamp 20 to be connected to other mounting bases.

[0053] In summary, the automatic cooling and dust-proof LED work lamp 20 of the present invention can reduce the dust accumulated on the work lamp during the non-working stage, and more effectively remove the dust on the work lamp during working, thereby achieving the purpose of cooling and improving the heat dissipation performance.

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
