[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A heat conducting plate 82 is fixedly connected to the right side of the box body 81. A heat conducting paste 83 is fixedly connected to the left side of the inner wall of the heat conducting plate 82. The right side of the heat conducting paste 83 is in contact with the left side of the lamp board 6.
[0024] As a technical optimization solution of the utility model, a heat dissipation mechanism 8 is provided, which is fitted with the lamp board 6 through a thermal conductive sticker 83 during use, absorbs the heat of the lamp board 6 through the thermal conductive sticker 83, and then conducts the heat to the heat conductive plate 82, and then conducts the heat to the heat dissipation fins 9 through the heat conductive plate 82.
[0025] refer to Figure 3 A heat dissipation fin 9 is fixedly connected to the left side of the heat conducting plate 82 . A plurality of heat dissipation fins 9 are provided and the plurality of heat dissipation fins 9 are distributed at equal distances. The inner wall of the box body 81 is filled with coolant.
[0026] As a technical optimization solution of the utility model, by setting the heat dissipation fins 9, when the heat conducting plate 82 transfers the heat to the heat dissipation fins 9, the heat is transferred to the coolant through the heat dissipation fins 9, so as to quickly reduce the heat of the lamp board 6, and the lamp board 6 can be quickly cooled when in use.
[0027] refer to Figure 3 A fixing frame 10 is fixedly connected to the top of the left side of the inner wall of the fixing shell 4, and a cooling box 11 is fixedly connected to the inner wall of the fixing frame 10.
[0028] As a technical optimization solution of the utility model, a fixing frame 10 and a cooling box 11 are provided, and the cooling box 11 is fixed by the fixing frame 10 to prevent the cooling box 11 from moving during use. When in use, heat is conducted to the coolant through the heat dissipation fins 9. When the temperature of the coolant in the box body 81 increases, it will enter the bottom of the cooling box 11 and be cooled away from the heat source.
[0029] refer to Figure 3 A connecting pipe 12 is fixedly connected to the right side of the top of the box body 81, and the other end of the connecting pipe 12 is connected to the top of the cooling box 11. A connecting pipe 2 13 is fixedly connected to the bottom of the left side of the box body 81, and the other end of the connecting pipe 2 13 is connected to the top of the left side of the cooling box 11.
[0030] As a technical optimization scheme of the utility model, by setting connecting pipe 12 and connecting pipe 2 13, the coolant in the box body 81 is transported to the bottom of the cooling box 11 through connecting pipe 12, and then after the coolant enters the cooling box 11, it will push the coolant upward, so that the coolant at the top enters connecting pipe 2 13, and the coolant is transported to the bottom of the box body 81 through connecting pipe 2 13, so as to achieve the effect of circulating heat dissipation.

[0032] As a technical optimization solution of the utility model, by setting a partition 14 and a reaming hole 15, the cooling box 11 is separated by the partition 14 to form three spaces. The coolant with a higher temperature enters the bottom of the cooling box 11, and the coolant at the bottom of the cooling box 11 enters the reaming hole 15 and enters the middle space, so that the coolant at the bottom of the cooling box 11 is cooled down, and the partition 14 is used to prevent coolants of different temperatures from mixing together.
[0033] refer to Figure 4 Both sides of the top of the inner wall of the expansion hole 15 are fixedly connected with a check ring 16, and the check ring 16 is set obliquely.
[0034] As a technical optimization solution of the utility model, by setting a check ring 16, the coolant can smoothly enter the expansion hole 15 after entering it from bottom to top. When the coolant enters the expansion hole 15 from top to bottom, it will be resisted by the check ring 16, reducing the speed of the coolant.
[0035] The working principle and use process of the utility model are as follows: when in use, the outer shell 1 is used to protect the internal circuits and batteries, and then the angle of the fixed shell 4 can be adjusted during use through the bracket 2 and the movable shaft 3. When in use, the light is emitted through the lamp panel 6, and then the light is refracted through the reflector 7 to illuminate the power-off area. When in use, the heat-conducting sticker 83 is attached to the lamp panel 6, and the heat of the lamp panel 6 is absorbed by the heat-conducting sticker 83, and then the heat is transferred to the heat-conducting plate 82, and then the heat is transferred to the heat dissipation fins 9 through the heat-conducting plate 82. When the heat-conducting plate 82 transfers the heat to the heat dissipation fins 9, the heat is transferred to the coolant through the heat dissipation fins 9 to quickly reduce the heat of the lamp panel 6. The lamp panel 6 can be quickly cooled during use. The cooling box 11 is fixed by the fixing frame 10 to prevent the cooling box 11 from moving during use. When in use, the heat is transferred to the coolant through the heat dissipation fins 9. When the coolant temperature in the box body 81 is The rising temperature will enter the bottom of the cooling box 11 and cool down away from the heat source. The cooling liquid in the box 81 is transported to the bottom of the cooling box 11 through the connecting pipe 12. Then, after the cooling liquid enters the cooling box 11, it will push the cooling liquid upward, so that the cooling liquid at the top enters the connecting pipe 2 13, and the cooling liquid is transported to the bottom of the box 81 through the connecting pipe 2 13, so as to achieve the effect of circulating heat dissipation. The cooling box 11 is separated by the partition 14 to form three spaces. The cooling liquid with higher temperature enters the bottom of the cooling box 11, so that the cooling liquid at the bottom of the cooling box 11 enters the expansion hole 15 and enters the middle space, so that the cooling liquid at the bottom of the cooling box 11 is cooled. The partition 14 is used to prevent the cooling liquids of different temperatures from mixing together. After the cooling liquid enters the expansion hole 15 from the bottom to the top, it can enter smoothly. When the cooling liquid enters the expansion hole 15 from the top to the bottom, it will be resisted by the check ring 16, thereby reducing the speed of the cooling liquid.
[0036] To sum up: this internal heat dissipation mechanism of an emergency LED lamp, by setting up an outer shell 1, protects the internal circuit and battery through the outer shell 1 when in use, and then through the bracket 2 and the movable shaft 3, the angle of the fixed shell 4 can be adjusted when in use, and the light is emitted through the lamp panel 6 when in use, and then the light is refracted through the reflector 7 to illuminate the power-off area, which solves the problem that the LED emergency light will continue to emit heat after the lamp is lit when the power is off, and when the power outage time is long, the heat of the lamp will continue to rise, and when the temperature is high, the service life of the lamp will be reduced.
