[0020] like Figure 1 and Figure 2 As shown, the present invention discloses an adjustable temperature-reducing and dust-proof LED work lamp 10 , which includes a lamp body 20 and a power supply assembly 30 mounted on the lamp body 20 .

[0021] like Figure 4 As shown, the power supply assembly 30 includes a power supply housing 100 and an active heat dissipation matrix system 200 housed in the power supply housing 100; the power supply housing 100 is an annular cavity structure with one end closed and the other end open, and the power supply housing 100 has an air inlet 110 and an air outlet 120, the air inlet 110 is opened at the annular cavity wall of the power supply housing 100, and the air outlet 120 is opened toward the lamp body 20.

[0022] like Figure 3 As shown, the active heat dissipation matrix system 200 is used to draw air from the air inlet 110 and blow it out from the air outlet 120 .

[0023] The specific structure of the active heat dissipation matrix system 200 is described below: like Figure 5 As shown, the active cooling matrix system 200 includes two stacked layers: a top cooling matrix module 300 and a bottom cooling matrix module 400. The top cooling matrix module 300 has a plurality of top fan units 310 arranged in a matrix, and the bottom cooling matrix module 400 has a plurality of bottom fan units 410 arranged in a matrix. The top fan units 310 and the bottom fan units 410 are arranged in a one-to-one correspondence. A signal receiver is installed on the active cooling matrix system 200, allowing the fan units of the cooling matrix system 200 to be controlled from a remote control on the ground. like Figure 6 As shown, the top fan unit 310 includes a top fan frame 320 and a top fan 330. The top fan 330 is arranged in the top fan frame 320 so as to be rotatable around the axis and reciprocatingly movable along the axis. The bottom fan unit 410 includes a bottom fan frame 420 and a bottom fan 430. The bottom fan 430 is arranged in the bottom fan frame 420 so as to be rotatable around the axis and reciprocatingly movable along the axis. Figure 6 As shown, in this embodiment, the top fan 330 is arranged in the top fan frame 320 and can be reciprocated along the axis through the top return spring 331, and the bottom fan 430 is arranged in the bottom fan frame 420 and can be reciprocated along the axis through the bottom return spring 431.

[0024] The end surface of the top fan 330 and the corresponding end surface of the bottom fan 430 are in contact with each other and meshed with each other through the teeth and grooves. Figure 6As shown, in this embodiment, a protruding tooth 332 is provided on the end surface of the top fan 330 , and a groove 432 is provided on the end surface of the bottom fan 430 , and the protruding tooth 332 and the groove 432 are engaged with each other.

[0025] The working principle of the above-mentioned adjustable cooling and dustproof LED work light 10 is described below: The lamp body 20 generates heat during normal operation and needs to be cooled. like Figure 6 As shown, before the lamp body 20 is officially blown and cooled, the top fan 330 and the bottom fan 430 are controlled to rotate in opposite directions respectively. For example, in the same observation direction, the top fan 330 is controlled to rotate clockwise, and the bottom fan 430 is controlled to rotate counterclockwise. As a result, the end faces of the top fan 330 and the bottom fan 430 that abut each other will collide under the action of the meshing teeth and grooves. The top fan 330 and the bottom fan 430 reciprocate along the axis to generate vibration, thereby shaking off stubborn dust, mosquito corpses and other dirt accumulated on the fan blades in the form of vibration, thereby achieving cleaning of the fan blades; in addition, when the top fan 330 and the bottom fan 430 reciprocate along the axis to generate vibration, the entire work lamp will also vibrate, thereby driving away birds that may nest on the lamp, effectively protecting the use safety of the lamp and increasing the service life of the lamp; controlling the rotation speed of the fan can achieve the effect of adjusting the vibration frequency; After a period of vibration, the top fan 330 and the bottom fan 430 are controlled to rotate in the same direction and at the same speed. For example, in the same viewing direction, the top fan 330 and the bottom fan 430 are controlled to rotate clockwise at the same speed. Thus, the top fan 330 and the bottom fan 430 no longer move relative to each other, and no reciprocating axis movement and vibration are generated. The top fan 330 and the bottom fan 430 rotate in the same direction and at the same speed, sucking air from the air inlet 110 and blowing it out from the air outlet 120, thereby achieving cooling of the lamp body 20; As can be seen from the above, the present invention only requires structural improvements to the fan itself. On the basis of being able to achieve its own heat dissipation function, it is only necessary to control the rotation direction of the top and bottom fans to switch back and forth between the vibration function and the heat dissipation function. In the present invention, one top fan unit 310 and the corresponding bottom fan unit 410 are referred to as a group. Then, a plurality of top fan units 310 and a plurality of bottom fan units 410 distributed in a matrix form a plurality of groups of fan units. Each group of fan units can be controlled in combination as needed. For example, one group of fan units is turned on, two groups of fan units are turned on one side, two groups of fan units are turned on diagonally, three groups of fan units are turned on, and four groups of fan units are turned on. In this way, an asymmetric airflow is generated, which can better blow away dust and the like on the lamp body 20. In addition, several groups of fan units can be controlled independently to prevent heat dissipation failure due to the cessation of work of a single group of fan units; It should also be noted that, in the present invention, the air inlet 110 is opened at the annular cavity wall of the power supply housing 100, and the air outlet 120 is opened toward the lamp body 20. The air inlet 110 is a very narrow annular opening. Such a structural design can effectively prevent large particles of foreign matter from being drawn into the cavity. The air outlet 120 is a wide opening. Such a structural design can blow the maximum wind force toward the lamp body 20 for heat dissipation. In this embodiment, a handle 40 is provided on the lamp body 20 , and the handle 40 can be used to install the lamp body 20 on a supporting hanging object, and the angle of the lamp body 20 can also be adjusted.

[0026] In this embodiment, the lamp body 20 includes a lamp housing 21 and a light-emitting component 22 provided on the lamp housing 21. Preferably, the light-emitting component 22 is an LED lamp, and the lamp housing 21 has heat dissipation fins 23.

[0027] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
