Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a high-brightness LED lamp for underwater operations. Background Art

[0002] With the continuous increase of marine activities, especially in the fields of marine research, fisheries, and leisure and entertainment, the demand for LED lamps for underwater lighting has increased significantly. Divers generally need to equip themselves with underwater LED lighting fixtures on the bottom of the boat or on their bodies for night diving operations, seabed exploration and research, and deep-water expeditions. These lamps can effectively illuminate the underwater environment, help divers observe underwater conditions, and ensure deep diving safety.

[0003] Deficiencies of existing technology:

[0004] At present, most common underwater operation lamps use LED as light source, and their basic structure consists of waterproof sealed shell, control unit and lighting unit. Due to the need for heat dissipation, they are generally equipped with heat conduction structure for heat dissipation. In particular, high-brightness LED diving lamps have large heat dissipation needs. In order to ensure the heat dissipation effect, liquid cooling heat dissipation structure is mostly used. Although liquid cooling structure is used to solve the heat dissipation problem, high-brightness LED diving lamps have high power, and the coolant in the lamp body is generally closed and static due to the working environment. It is difficult to effectively transfer heat to the surrounding environment. If it continues to work for a long time, the temperature inside the lamp will still be too high, which will eventually reduce the life of the lamp or even burn it out directly. Therefore, in actual applications, the heat dissipation needs of high-brightness LED lamps for underwater operations are still difficult to meet. Utility Model Content

[0030] See also Figure 1-3 As shown, the utility model provides a technical solution for a high-brightness LED lamp for underwater operations: a high-brightness LED lamp for underwater operations, comprising a fixed bracket 1, a liquid cooling component 2 is installed at the lower end of the fixed bracket 1, a driving mechanism 3 is installed at the lower end of the liquid cooling component 2, a control unit 4 is installed on the inner side of the liquid cooling component 2, and an illumination unit 5 is connected to one end of the liquid cooling component 2 and the control unit 4; the driving mechanism 3 comprises a guide cover 301, an isolation cover 302 and a transmission shaft 303, the guide cover 301 is installed below the liquid cooling component 2, the isolation cover 302 is installed below the liquid cooling component 2 and located on the inner side of the guide cover 301, the isolation cover 302 is used to separate the coolant and the external water, the transmission shaft 303 is horizontally sealed and installed on the isolation cover 302, the end of the transmission shaft 303 located outside the isolation cover 302 is installed with a first impeller 304, and the end of the transmission shaft 303 located inside the isolation cover 302 is installed with a second impeller 305. When the diver is moving, the external water flow enters from the front end of the deflector 301, and then flows along the lower end surface of the isolation cover 302 at an accelerated speed. The water flow contacts the isolation cover 302 while flowing, and performs heat exchange and cooling on the coolant in the isolation cover 302. Then the water flow continues to flow backward to drive the first impeller 304 to rotate. The first impeller 304 drives the second impeller 305 inside the isolation cover 302 to rotate through the transmission shaft 303. Under the rotation of the second impeller 305, the coolant in the isolation cover 302 is driven to start flowing and circulate with the coolant in the liquid cooling component 2, and the high-temperature coolant in the liquid cooling component 2 is introduced into the isolation cover 302 for heat exchange. Through the driving mechanism 3, the coolant in the entire lamp is circulated and heat exchanged with the isolation cover 302, so as to avoid the heat accumulation of the coolant inside the lamp and cause the temperature to be too high, further improve the cooling efficiency of the liquid cooling component 2, and also improve the service life of the lamp. In addition, the flowing water flow is used to synchronously drive the second impeller 305 during the movement of the diver, so as to improve the utilization rate of energy and reduce energy loss.

[0031] The liquid cooling assembly 2 includes a liquid cooling box 201, a flow hole 203 and a drain port 204. The liquid cooling box 201 is installed at the lower end of the fixed bracket 1. The interior of the liquid cooling box 201 is filled with coolant. A plurality of partitions 202 are installed on the inner side of the liquid cooling box 201. The control unit 4 is installed in the mounting hole opened on the partition 202. The open end of the liquid cooling box 201 is connected to the lighting unit 5. The flow holes 203 are staggered up and down on the partition 202. The drain port 204 is opened on the side of the lower end of the liquid cooling box 201 adjacent to the lighting unit 5. A return port 205 is opened on the side of the lower end of the liquid cooling box 201 away from the drain port 204. When the liquid cooling assembly 2 is working, the coolant in the isolation cover 302 is discharged from the drain port 204 driven by the second impeller 305, enters the liquid cooling box 201, and then alternately passes through the flow holes 203 on the partition 202 up and down according to the preset path, and finally enters the isolation cover 302 through the return port 205 for heat exchange. During the flow of the coolant, the coolant dissipates heat to one end of the lighting unit 5 and the outside of the control unit 4. Through the liquid cooling assembly 2, the circulation path of the coolant in the liquid cooling box 201 is optimized, and the overall heat dissipation effect is more balanced, which better meets the heat dissipation requirements of current high-power LED lighting lamps.

[0032] The interior of the isolation cover 302 and the liquid cooling box 201 are both filled with cooling liquid. Completely filling the box with cooling liquid is conducive to better circulation of the cooling liquid inside the lamp.

[0033] A plurality of fins 6 are installed on the outside of the control part 4 between the partitions 202 . The fins 6 can better conduct the heat inside the control part 4 and improve the heat exchange efficiency.

[0034] Filter screens 7 are installed at both ends of the flow guide cover 301 , and the filter screens 7 can prevent impurities in the water from entering the flow guide cover 301 and damaging the first impeller 304 .

[0035] The opening size of the liquid inlet end of the guide cover 301 is larger than the opening size of the liquid discharge end. The size of the liquid inlet end is larger than the liquid discharge end, which can ensure that the water flow has an acceleration effect when being discharged, and further improve the circulation effect of the coolant.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
