When construction needs to be carried out at night on the construction site, engineering lights can provide light sources to facilitate the construction. In addition, in order to provide sufficient light, high-power lighting is generally required.

[0003] When using high-power lighting lamps, since the power of the lighting lamps themselves is relatively large and high-power lighting lamps need to be turned on and running for a long time in the engineering field, the long-term operation of the lighting lamps will cause the temperature of the lamp body to rise. The existing engineering lamps are not equipped with heat dissipation mechanisms, and the lamp body remains in a high temperature state for a long time, which can easily cause damage to the engineering lamps.

[0004] Therefore, it is urgent to improve high-power engineering lamps to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figure 1-Figure 4 As shown, the high-power engineering lamp with a self-heating mechanism provided in this embodiment includes a lamp housing 1, and both sides of the upper end surface of the lamp housing 1 are provided with hanging rings 13, and the setting of the hanging rings 13 realizes the installation of the lamp board;

[0024] A plurality of cooling fans 2 are rotatably connected to the upper surface of the interior of the lamp housing 1, and a lamp board 3 fixed to the interior of the lamp housing 1 is arranged below the cooling fan 2, and the lamp housing 1 is engaged through a transparent cover plate 8; a card slot for engaging the transparent cover plate 8 is arranged on the lower end surface of the lamp housing 1, and the card slot and the transparent cover plate 8 are provided with interconnected magnetic suction sockets, and a magnetic suction rod is inserted into the magnetic suction socket. When the lamp board 3 needs to be inspected, the magnetic suction rod is pulled out, and the transparent cover plate 8 can be quickly removed. After the inspection is completed, the transparent cover plate 8 is directly inserted into the card slot, and the two magnetic suction sockets are connected, and then the magnetic suction rod can be inserted;

[0025] A plurality of heat dissipation mechanisms 4 are arranged above the lamp housing 1, and a ventilation duct 5 connected to the heat dissipation mechanism 4 is arranged on the front face of the lamp housing 1. The ventilation duct 5 penetrates the lamp housing 1 and is connected to a blowing duct 6 for driving the heat dissipation fan 2 to rotate;

[0026] The heat dissipation mechanism 4 includes a driving motor 17, a sealed cavity 14, and a heat dissipation blade 9 connected to the output end of the driving motor 17. The heat dissipation blade 9 is in the sealed cavity 14. The sealed cavity 14 is connected to the ventilation duct 5 through a connecting pipe 15. The sealed cavity 14 is supported and fixed by a support block 16. When it is necessary to dissipate heat inside the lighting lamp, the heat dissipation blade 9 is driven by the driving motor 17 to rotate in the sealed cavity 14, thereby generating air volume. The air volume enters the ventilation duct 5 through the connecting pipe 15, and then enters the lighting lamp. Part of the wind source will directly blow into the lamp housing 1 to blow away the internal heat and discharge it through the exhaust channel 7. Another part of the wind source will blow to the heat dissipation fan 2 through the blowing duct 6, so that the heat dissipation fan 2 rotates to achieve further heat dissipation inside the lamp housing 1.

[0027] Furthermore, the air outlet of the air blowing duct 6 faces the cooling fan 2, ensuring that the wind blown out through the air blowing duct 6 can blow the cooling fan 2, and cooperate with the internal circulating wind to effectively improve the heat dissipation effect inside the lamp housing 1;

[0028] A plurality of exhaust passages 7 are arranged on the side of the lamp housing 1 away from the ventilation duct 5; the exhaust passage 7 includes a first pipe 701 connected to the lamp housing 1 and a second pipe 702 connected to the outer side of the lower end surface of the first pipe 701, and a rainproof structure is arranged inside the second pipe 702; the rainproof structure includes a first baffle 10 and a second baffle 11 which are arranged on both sides of the second pipe 702 and are upturned, and the first baffle 10 and the second baffle 11 are not in contact with the inner wall of the second pipe 702 on the side away from the connection end, and the two staggered and upturned first baffles 10 and the second baffle 11 can effectively prevent rainwater from entering the interior of the lamp housing 1 through the exhaust passage 7, thereby preventing damage to the internal lamp board 3.

[0029] like Figure 1-Figure 4 As shown, the principle of the high-power engineering lamp with a self-heating mechanism provided in this embodiment is as follows: when the lighting lamp reaches a high temperature after a long period of operation, the heat dissipation blades 9 are driven by the driving motor 17 to rotate in the sealed cavity 14, thereby generating air volume. The air volume enters the ventilation duct 5 through the connecting pipe 15 and then enters the interior of the lighting lamp. Part of the wind source will directly blow into the interior of the lamp housing 1 to blow away the internal heat and discharge it through the exhaust channel 7. Another part of the wind source will blow to the heat dissipation fan 2 through the blowing duct 6 to rotate the heat dissipation fan 2 to achieve further heat dissipation inside the lamp housing 1, and cooperate with the internal circulating wind to effectively improve the heat dissipation effect inside the lamp housing 1.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0032] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
