[0028] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 6 As shown, a searchlight comprises a base 1, and a rotatable bracket 2 is arranged on the base 1, and a rotatable lamp tube 3 is arranged on the bracket 2, and the lamp tube 3 comprises a shell 31 and a pressing ring 32, and the shell 31 and the pressing ring 32 are connected by a buckle assembly 5.

[0030] Therefore, in actual use, the buckle assembly 5 is more convenient for installing the pressure ring 32 than the screw connection.

[0031] At the same time, the shell 31 has an annular mounting plate 33 built in, and a light source 34 and a heat sink 35 are respectively arranged on both sides of the mounting plate 33, and the heat sink 35 is provided with a light source 34 on the side close to the pressing ring 32, and the shell 31 is provided with a plurality of heat dissipation holes 312 behind the mounting plate 33.

[0032] Therefore, in actual use, a better heat dissipation effect is achieved through the cooperation of the heat dissipation holes 312 and the radiator 35.

[0033] Moreover, a sealing ring 4 is arranged between the shell 31 and the pressing ring 32, and the heat sink 35 is connected to the mounting plate 33 on the side close to the pressing ring 32, and a sealing ring 2 6 is arranged between the heat sink 35 and the mounting plate 33. Secondly, a cable lock 7 is used to lock and seal the wires of the light source 34 and the heat sink 35, so that the space between the pressing ring 32 and the heat sink 35 is a closed space.

[0034] Therefore, in actual use, the light source 34 is located between the pressing ring 32 and the heat sink 35 so as to better protect the light source 34 , that is, better heat dissipation is achieved without causing damage to the light source 34 .

[0035] Moreover, the cable lock 7 (also called "clamp") is one of the electrical connection devices widely used in power systems and industrial and mining enterprises, and mainly plays a protective role in the power system. At the same time, its structure is diverse and can be selected according to actual conditions.

[0036] like Figure 4 As shown, the buckle assembly 5 is an existing commonly used structure, and an example is given here: first, the buckle assembly 5 includes a bent hook 51 arranged on the pressure ring 32, and a limiting member 53 and a rotating plate 54 arranged on the shell 31, and the rotating plate 54 has a limiting hole corresponding to the limiting member 53, and the fastener 52 is rotatably arranged on the rotating plate 54.

[0037] Therefore, in actual use, the fastener 52 is connected to the hook 51 by rotating the rotating plate 54, and then the pressure ring 32 is connected to the shell 31. When the fastener 52 is connected to the hook 51, the rotating plate 54 can be rotated so that the limiting member 53 is located in the limiting hole, thereby limiting the separation of the fastener 52 and the hook 51.

[0038] like Figure 4 As shown, the structure of the sealing ring 4 is: first, a transparent part 36 is arranged between the pressing ring 32 and the shell 31, and the pressing ring 32 is provided with a hole for exposing the transparent part 36, and the sealing ring 4 is sleeved on the outside of the transparent part 36, and the part of the pressing ring 32 located around the hole is located in the groove opened by the sealing ring 4.

[0039] Therefore, through the arrangement of the above structure, a single sealing ring 4 can achieve two seals between the pressing ring 32 and the shell 31 and between the pressing ring 32 and the transparent member 36.

[0040] like Figure 4 and Figure 5 As shown, the structure of the sealing ring 2 6 is as follows: first, the mounting plate 33 and the radiator 35 are connected by fasteners, and the radiator 35 is provided with sealing rings 2 6 on both sides of the fasteners on the side close to the pressing ring 32. Therefore, in actual use, better sealing is achieved by providing two sealing rings 2 6.

[0041] The structure between the second sealing ring 6 and the heat sink 35 is as follows: first, the heat sink 35 is provided with a groove 351 , and the second sealing ring 6 is located in the groove 351 .

[0042] like Figure 5 As shown, at least one light source substrate 37 is disposed on the heat sink 35 , and the light source substrate 37 is manufactured through a thermoelectric separation process.

[0043] Among them, thermoelectric separation is a new growth technology that drives the ejection of atoms and molecules of graphene and other materials under high temperature and high pressure by temperature difference. Moreover, copper substrates are important carrier materials in high-end electronic products. Copper substrates prepared by thermoelectric separation technology have good performance advantages in high-frequency transmission and thermal transmission.

[0044] Secondly, the light source substrate 37 is not a single one, but a plurality of them are arranged, so that the hot spots can be dispersed, thereby accelerating the heat conduction and increasing the life of the light source.

[0045] like Figure 6 As shown, the rotation of the bracket 2 and the lamp tube 3 is an existing commonly used structure, and an example is given here: first, a rotating shaft 8 is arranged between the base 1 and the bracket 2, and the rotating shaft 8 is connected to a motor 9 and a bearing 10 is arranged between the base 1, and the rotating shaft 8 is driven to rotate by the motor 9, thereby driving the bracket 2 to rotate.

[0046] At the same time, the bracket 2 and the lamp tube 3 are connected through a worm gear assembly, and the worm gear assembly is connected to a motor 20. The worm gear assembly is driven by the motor 1 9 to drive the lamp tube 3 to rotate.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. At the same time, the utility model is not limited by the above embodiments, so without departing from the principle and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model claimed for protection.
