Problems solved by technology

[0002] With the continuous improvement of people's performance requirements for flashlights, high-power LEDs are used in the prior art to meet market demand. When meeting strong lighting conditions, flashlights will generate a lot of heat when they work. If the flashlight's LED or Other components generate high temperature, which will cause the flashlight to fail, and seriously cause safety accidents
[0003] In addition, the flashlights in the prior art have poor sealing performance. Usually only the sealing ring is used as the main sealing means for sealing. It is difficult to meet the requirements of waterproof and sealing in complex environments. There are cooling holes on the body, which reduces the sealing and waterproof performance of the flashlight

Embodiment 1

[0048] like Figure 1-Figure 9 As shown, the present invention provides a flashlight, which includes a barrel body 1, a lamp cap 2, a light-emitting assembly 3, a heat dissipation assembly 4, a reflector 5, and a tail cover 6. A switch 11 and a light guide 12 are integrally provided on the barrel body 1. The body 1 has a receiving hole 100, and the power supply 13 is arranged in the receiving hole 100; the lamp cap 2 is connected to one end of the barrel body 1, and the connection between the lamp cap 2 and the barrel body 1 is provided with a first sealing ring 211, and the lamp cap 2 has a containing cavity 200; The assembly 3 is arranged in the accommodation chamber 200 and is electrically connected to the power supply 13; the heat dissipation assembly 4 is arranged in the accommodation chamber 200 and abuts against the light emitting assembly 3; the reflector 5 is arranged in the accommodation chamber 200 and abuts against the light emitting assembly 3, which can Reflect t...

Embodiment 2

[0071] like Figure 10-12 As shown, this embodiment provides a flashlight, which is different from the flashlight of the first embodiment above in that the heat dissipation assembly 4 in the flashlight of this embodiment does not include a heat sink 41, and the first circuit board 32 is in contact with the heat spreader 42 to reflect light. The outer periphery of the cover 5 is directly attached to the cavity wall of the accommodation cavity 200, and the lamp cap 2 assembly does not use the heat sink 41 to conduct heat dissipation. The cavity wall of 200 is in close contact. When the reflector 5 is set as a metal material, the reflector 5 directly contacts the cavity wall of the containing cavity 200 to conduct heat, and the heat dissipation effect is better, and the heat can be quickly transferred to the lamp holder in a large area. 2 and dissipated by the heat sink 212 for heat dissipation.

[0072] In particular, when the flashlight is working, the heat generated inside the ...

Abstract

The invention relates to the technical field of illumination, in particular to a flashlight which comprises a flashlight body, a lamp holder, a light-emitting assembly, a heat dissipation assembly, a reflecting cover and a tail cover, a switch and a light guide part are integrally arranged on the flashlight body, the flashlight body is provided with a containing hole, and a power source is arranged in the containing hole; the lamp holder is connected to one end of the flashlight body, a first sealing ring is arranged at the joint of the lamp holder and the flashlight body, and the lamp holder is provided with a containing cavity. The light-emitting assembly is arranged in the containing cavity and electrically connected with the power source. The heat dissipation assembly is arranged in the containing cavity and abuts against the light-emitting assembly. The reflecting cover is arranged in the containing cavity, abuts against the light-emitting assembly and can reflect light emitted by the light-emitting assembly. The tail cover is connected to the other end of the cylinder body, and a second sealing ring is arranged between the tail cover and the cylinder body. The flashlight provided by the invention has a good rapid heat dissipation effect, and the flashlight body is integrally provided with the switch and the light guide piece, and the first sealing ring and the second sealing ring are respectively arranged at the joint of the lamp cap and the tail cover, so that the waterproof sealing requirement in a complex environment can be met.

technical field [0001] The invention relates to the technical field of lighting, in particular to a flashlight. Background technique [0002] With the continuous improvement of people's performance requirements for flashlights, high-power LEDs are used in the prior art to meet market demand. When meeting strong lighting conditions, flashlights will generate a lot of heat when they work. If the flashlight's LED or Other components generate a higher temperature, which will cause the flashlight to fail, and seriously cause a safety accident. [0003] In addition, the flashlights in the prior art have poor sealing performance. Usually only the sealing ring is used as the main sealing means for sealing. It is difficult to meet the requirements of waterproof and sealing in complex environments. There are cooling holes on the body, which reduces the sealing and waterproof performance of the flashlight. [0004] Therefore, aiming at the high-power flashlights in the prior art, it ...
