Technical Field

[0001] This utility model relates to the field of LED flashlight technology, specifically to an LED flashlight with a light source adjustment mechanism. Background Technology

[0002] LED flashlights are a new type of flashlight that uses LEDs (light-emitting diodes) as their light source. Because LEDs have the characteristics of high brightness, low power consumption, long lifespan, and small size, they are an ideal choice for portable lighting.

[0003] According to announcement number CN111156436B, a flashlight aperture adjustment device includes a fixed plate, an adjustment mechanism, a color-changing mechanism, and a fixing mechanism. The fixing mechanism is fixedly connected to the fixed plate and the color-changing mechanism.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, the device mainly adjusts the color of the flashlight's light according to the needs of different occasions. However, this adjustment does not involve changing the light intensity. Therefore, in indoor environments, outdoor workplaces, and even wilderness explorations where a stronger light source is needed to illuminate the surrounding environment, the current flashlight adjustment function is inadequate and cannot meet the actual needs. Utility Model Content

[0006] The purpose of this invention is to provide an LED flashlight with a light source adjustment mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LED flashlight with a light source adjustment mechanism, comprising an LED flashlight and a fixing ring, wherein an LED bead is electrically connected to the left side of the LED flashlight, a connecting ring is fixedly connected to the left surface of the LED flashlight, a connecting mechanism is provided on the fixing ring and the connecting ring, and an adjustment mechanism is provided on the fixing ring;

[0008] The adjustment mechanism includes a T-shaped annular groove, which is located on the left side of the connecting ring. A T-shaped annular slider is fixedly connected to the right side of the fixing ring. A mounting ring is fixedly connected to the left side of the fixing ring. An internal thread is provided on the inner side of the mounting ring. A lens ring is provided on the left side of the fixing ring. An external thread is provided on the surface of the lens ring.

[0015] Compared with the prior art, the present invention provides an LED flashlight with a light source adjustment mechanism, which has the following beneficial effects:

[0016] 1. This LED flashlight with a light source adjustment mechanism uses the adjustment mechanism to rotate the fixing ring, causing the T-shaped annular slider to slide within the T-shaped annular groove. This allows a convex or concave mirror to be positioned on the left side of the LED bead. When the convex mirror is positioned on the left side of the LED bead, the light intensity will be further enhanced. When the concave mirror is positioned on the left side of the LED bead, the light intensity will be weakened. By moving the lens ring, the external and internal threads are connected, allowing the convex or concave mirror on the lens ring to be replaced periodically.

[0017] 2. This LED flashlight with a light source adjustment mechanism uses a hinge plate and a plug plate inserted into a rectangular slot. The hinge plate drives the plug block to be inserted into the slot. By rotating the locking plate on one side of the hinge plate, the locking plate drives the locking block to be engaged in the slot, thus limiting and fixing the position of the fixing ring. This allows the convex or concave mirror to be fixed on the left side of the LED bead, facilitating long-term use of the LED flashlight. Attached Figure Description

[0028] Example 1

[0029] Combination Figures 1 to 3 An LED flashlight with a light source adjustment mechanism includes an LED flashlight 1 and a fixing ring 4. An LED bead 6 is connected to the left side of the LED flashlight 1. A connecting ring 2 is fixedly connected to the left side surface of the LED flashlight 1. A connecting mechanism 5 is provided on the fixing ring 4 and the connecting ring 2. An adjustment mechanism 3 is provided on the fixing ring 4.

[0030] The adjustment mechanism 3 includes a T-shaped annular slide groove 31, which is located on the left side of the connecting ring 2. A T-shaped annular slider 34 is fixedly connected to the right side of the fixing ring 4. An installation ring 38 is fixedly connected to the left side of the fixing ring 4. An internal thread 35 is provided on the inner side of the installation ring 38. A lens ring 37 is provided on the left side of the fixing ring 4. An external thread 36 is provided on the surface of the lens ring 37. A convex mirror 32 is densely fixedly connected to the right side of the lens ring 37. A concave mirror 33 is densely fixedly connected to the right side of the lens ring 37.

[0031] There are four T-shaped annular sliders 34. The surfaces of the four T-shaped annular sliders 34 are slidably connected to the inside of the T-shaped annular groove 31. The outer diameters of the concave mirror 33 and the convex mirror 32 are larger than the outer diameter of the lamp bead 6. The concave mirror 33 is located on one side of the convex mirror 32.

[0032] Furthermore, rotating the fixing ring 4 causes the T-shaped annular slider 34 to slide within the T-shaped annular groove 31, so that the convex mirror 32 or the concave mirror 33 is positioned on the left side of the lamp bead 6. When the convex mirror 32 is positioned on the left side of the lamp bead 6, the light intensity will be further enhanced. When the concave mirror 33 is positioned on the left side of the lamp bead 6, the light intensity will be weakened. Moving the lens ring 37 causes the external thread 36 and the internal thread 35 to be threaded together, so that the convex mirror 32 or the concave mirror 33 on the lens ring 37 can be replaced periodically.

[0033] Example 2

[0034] See Figure 1-5 Furthermore, based on Embodiment 1, the connecting mechanism 5 includes a fixed base 52, which is fixedly connected to the periphery of the surface of the connecting ring 2. Insert plates 59 are fixedly connected to the periphery of the surface of the fixed ring 4 respectively. A rectangular groove 51 is provided on the left side of the fixed base 52. A slot 53 is provided inside the insert plate 59. The side of the slot 53 away from the fixed ring 4 is set as an opening. An insert block 54 is inserted into the slot 53. A hinge plate 55 is fixedly connected to the left side of the insert block 54. A locking plate 56 is hinged to the left side of the hinge plate 55. A locking block 57 is fixedly connected to the right side of the locking plate 56. A slot 58 is provided on the left side of the insert plate 59.

[0035] The rectangular slot 51 is open on the left and both sides. The surface of the insert plate 59 is inserted into the inside of the rectangular slot 51. The slot 58 is open on the left side. The surface of the card block 57 is inserted into the inside of the card slot 58. The fixing seat 52 has a through slot on the side away from the connecting ring 2. The surface of the insert block 54 is inserted into the through slot on the side of the fixing seat 52 away from the connecting ring 2.

[0036] Furthermore, the insert plate 59 is inserted into the rectangular slot 51, and the hinge plate 55 drives the insert block 54 to be inserted into the slot 53. The locking plate 56 is rotated on one side of the hinge plate 55, so that the locking plate 56 drives the locking block 57 to be locked into the slot 58, thereby limiting and fixing the position of the fixing ring 4, so that the convex mirror 32 or the concave mirror 33 is fixed on the left side of the LED bead 6, which facilitates the long-term use of the LED flashlight 1.

[0037] In actual operation, when this device is in use, when the LED flashlight 1 is working normally, it is necessary to adjust the intensity of the light as needed. At this time, the T-shaped annular slider 34 can be moved by rotating the fixed ring 4 to slide in the T-shaped annular groove 31, so that the convex mirror 32 or the concave mirror 33 is placed on the left side of the LED bead 6. When the convex mirror 32 is placed on the left side of the LED bead 6, the light intensity will be further enhanced, and when the concave mirror 33 is placed on the left side of the LED bead 6, the light intensity will be weakened.

[0038] By rotating the lens ring 37, the external thread 36 and the internal thread 35 are connected, allowing the convex mirror 32 or concave mirror 33 on the lens ring 37 to be replaced periodically.

[0039] When the insert plate 59 is inserted into the rectangular slot 51, the hinge plate 55 drives the insert block 54 to be inserted into the slot 53. The locking plate 56 is rotated on one side of the hinge plate 55, so that the locking plate 56 drives the locking block 57 to be locked into the slot 58. This limits and fixes the position of the fixing ring 4, so that the convex mirror 32 or the concave mirror 33 is fixed on the left side of the LED bead 6, which is convenient for long-term use of the LED flashlight 1.
