AI Technical Summary
Existing multi-color LED flashlights suffer from excessive heat buildup due to the increased light source, which cannot be effectively dissipated, affecting their performance.
A copper plate is installed inside the flashlight to connect to a heat dissipation component. The heat from the light control board is conducted to the heat dissipation component through the copper plate, and the heat dissipation component is used to dissipate heat by contacting the outside environment.
The flashlight's heat dissipation capacity has been improved to meet the needs of multi-light source operation, ensuring the stability of the light source and user comfort.

Abstract
Description
Technical Field
[0001] This utility model relates to a flashlight with high heat dissipation capacity. Background Technology
[0002] LED flashlights are now widely used in daily life, but for most people, their light color is relatively simple and cannot be adjusted according to people's needs. Even though multi-color flashlights have appeared on the market, there are some problems. Because the light source has increased, the internal heat accumulates too much and cannot be effectively dissipated. Utility Model Content
[0003] To address the above problems, this technical solution provides a flashlight with high heat dissipation capability.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A flashlight with high heat dissipation capacity includes a flashlight body, one end of which is provided with a first light source and a second light source. A first button for controlling the first light source and the second light source to turn on and off is provided on the side wall of the flashlight body. A main control PCB board is provided inside the flashlight body. The main control PCB board is electrically connected to a lamp control board for connecting to the first light source and the second light source. The main control PCB board is also electrically connected to a button control board for connecting to the first button.
[0006] The lamp control board is connected to a copper plate for transferring heat from the board, and the copper plate is connected to a heat dissipation component that extends out of the flashlight body.
[0007] In some embodiments, the lamp control panel is also connected to a third light source located on the side wall of the flashlight body, and a second button is provided on one side of the first button for controlling the third light source to turn on or off.
[0008] In some embodiments, the heat dissipation component is a screw, which is also connected to a cover.
[0009] In some embodiments, the first button has an arc-shaped design with a recessed hole in its center.
[0010] In some embodiments, the second button has an arc-shaped design with a protrusion in the middle.
[0011] The beneficial effects of this application are:
[0012] This application incorporates a copper plate to guide the heat generated by the lamp control board out and transfer it to the heat dissipation component. Since the heat dissipation component is in contact with the outside, the heat can be dissipated to the outside, thereby greatly improving the heat dissipation capacity of the flashlight. Attached Figure Description
[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0014] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model;
[0015] Figure 2 This is a cross-sectional schematic diagram of an embodiment of the present utility model;
[0016] Figure 3 This is an omitted schematic diagram of an embodiment of the present invention. Detailed Implementation
[0017] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] Please refer to Figure 1-3 As shown, a flashlight with high heat dissipation capacity includes a flashlight body 1. One end of the flashlight body 1 is provided with a first light source 2 and a second light source 3. The side wall of the flashlight body 1 is provided with a first button 4 for controlling the first light source 2 and the second light source 3 to turn on and off. The flashlight body 1 is provided with a main control PCB board 5. The main control PCB board 5 is electrically connected to a lamp control board 6 for connecting to the first light source 2 and the second light source 3. The main control PCB board 5 is also electrically connected to a button control board 7 for connecting to the first button 4.
[0019] The lamp control board 6 is connected to a copper plate 8 for transferring heat from the board, and the copper plate 8 is connected to a heat dissipation component 9 that extends through the flashlight body 1.
[0020] This application incorporates a copper plate to guide the heat generated by the lamp control board out and transfer it to the heat dissipation component. Since the heat dissipation component is in contact with the outside, the heat can be dissipated to the outside, thereby greatly improving the heat dissipation capacity of the flashlight.
[0021] In this embodiment, the lamp control board 6 is also connected to a third light source 10 located on the side wall of the flashlight body 1. A second button 11 is provided on one side of the first button 4 to control the lighting of the third light source 10. This application has the effect of multiple light sources. By pressing the first button, the first light source and the second light source are lit. Then, by pressing the second button, the third light source is lit. This can meet the needs of users in different scenarios. At the same time, it is equipped with a good heat dissipation system and can support the operation of multiple light sources.
[0022] In this embodiment, the heat dissipation component 9 is a screw, which is also connected to a cover 12. The screw has the function of heat conduction. The screw is locked in the cover, which not only makes installation convenient, but also realizes heat transfer at the same time. Then the cover is used to dissipate the heat to the outside.
[0023] In this embodiment, the first button 4 has an arc-shaped design, with a recessed hole 13 in the middle.
[0024] In this embodiment, the second button 11 has an arc-shaped design with a protrusion 14 in the middle.
[0025] When the user holds the flashlight, since the first and second light sources are commonly used light sources, the first button is designed to be closer to the front of the flashlight. This is to make it easier for the user's thumb to press, and the buttons are more comfortable and easier to press. The second button is located closer to the rear side, and it has a raised design to make it easier for the thumb to bend and press.
[0026] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
