Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a variable focus lamp. Background Technology

[0002] A light source is focused by refraction through a lens, and the aperture size produced varies depending on the distance the light source and lens move. Moving either the lens or the light source to change the distance between them is called zooming, and this process allows for the dispersion and focusing of light as needed.

[0003] Modern zoom flashlights, zoom handheld lights, zoom portable lights, and zoom headlamps all have a fixed light source; zooming is achieved by pushing and pulling the lens and outer sleeve at the front. For example... Figure 1 and Figure 2 As shown, a lens with a sleeve is added to the front end of the lamp to form an outer sleeve, and the front end of the lamp becomes a sleeved design. In order to prevent slippage, some inner and outer sleeves are fitted with steel wire rings, some with rubber strips, etc., to make the inner and outer sleeves fit tightly and prevent them from sliding freely and failing to function properly. This is called achieving light zoom by moving the lens externally, or simply external zoom.

[0004] The above zoom method has the following drawbacks:

[0005] (1) Inconvenient to use, because the inner and outer covers are tightly interlocked, requiring both hands to exert force simultaneously to complete the simple process of zooming, such as Figure 1 and Figure 2 As shown, the aperture is either at its maximum or minimum, making it difficult to control the desired aperture size.

[0006] (2) Zoom flashlights, hand lamps and other lighting fixtures are practical tools. After the addition of a connecting structure at the front end, the overall integrity and sturdiness are compromised and the strength of the fixtures decreases.

[0007] (3) Short service life. Wear between the inner and outer sleeves is unavoidable. When new, they are very tight and can effectively prevent slipping. However, with repeated use, the frictional resistance will inevitably decrease rapidly. When the coefficient of friction between the inner and outer sleeves is zero, the size of the aperture cannot be controlled, which directly affects normal use. In other words, this moving zoom mode greatly shortens the service life of this type of lamp, which is a reality that manufacturers and users cannot avoid.

[0008] (4) As an electrical product, its protection level is greatly reduced after the addition of the socket structure;

[0009] (5) production cost increases. For example, the required distance for zooming is 20mm, the length of the sleeve reaches 50mm, the extra 30mm needs to be stacked with the inner sleeve to ensure the stability of the pulled front end, the inner sleeve also has the extra 30mm, the lens fixing ring and the outer sleeve pipe supporting its movement must open several molds, the production cost increases, the raw materials increase, and the labor cost also increases a lot.

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0048] Based on the defects described in the existing technology, such as Figures 3-10 The diagram shown is a structural schematic of the variable-focus lamp of this utility model. The variable-focus lamp includes a lamp body, a lens 120, and a light source assembly 1. The lens 120 is located at the end of the lamp body, and the light source assembly 1 is located inside the lamp body. It also includes a zoom assembly 2, which is located on the side of the light source assembly 1 opposite to the lens 120. The zoom assembly 2 is driven to connect with the light source assembly 1. The zoom assembly 2 drives the light source assembly 1 to move closer to or further away from the lens 120, and the zoom assembly 2 drives the light source assembly 1 to slide along the axial direction of the lamp body inside the lamp body.

[0049] The zoom component 2 of this invention can be operated with one hand, allowing for precise control of the aperture size while completely freeing the user's other hand. Furthermore, because it lacks a front-end connecting structure, the overall strength is significantly enhanced, and the protection level is greatly improved. This also expands the application range of zoom lights. Compared to existing external zoom lights, this invention significantly reduces manufacturing costs and effectively extends service life.

[0050] The following is a specific example. Figures 3-10 The variable focus lamp of this utility model will be described in detail in Examples 1-4.

[0051] Example 1

[0052] See Figure 3 As shown in Figure 4, the light source assembly 1 is cylindrical and includes an outer ring seat 11, an LED chip 12, a chip pressing component 13, and an aluminum substrate 14. The chip pressing component 13 and the aluminum substrate 14 are disposed on both sides of the LED chip 12, and the LED chip 12, the chip pressing component 13, and the aluminum substrate 14 are fixedly disposed on the axis of the outer ring seat 11.

[0053] The light source assembly 1 is very lightweight, generally not exceeding 20 grams, and its thickness is typically around 20 mm. External zoom flashlights also have a light source assembly 1, which is fixed to the inner wall of the lamp body via an outer ring seat 11 and cannot move. Unlike external zoom flashlights, the light source assembly 1 of this invention is separable from the inner wall of the lamp body. The outer diameter of the outer ring seat 11 is close to the inner diameter of the lamp body, and one or two grooves are cut on the side of the outer ring seat 11 for ventilation. This allows the light source assembly 1 to act like a piston, moving back and forth along the inner wall of the lamp body without deviation when driven. Simultaneously, the smoothness of this moving distance along the inner wall of the lamp body and the smoothness around the light source assembly 1 are ensured, and paraffin wax is sprayed for lubrication.

[0054] In this embodiment, the lamp body is preferably the body 100 of a flashlight, such as... Figure 4a , Figure 4b and Figure 4c As shown, the zoom component 2 includes a first metal part 21 and a moving key 22. One end of the first metal part 21 is fixedly connected to the aluminum substrate 14, and the other end of the first metal part 21 is fixedly connected to the moving key 22. The moving key 22 is located on the side wall of the flashlight body 100.

[0055] Specifically, the first metal part 21 includes a vertical surface and a rod body. The vertical surface and the rod body are integrally formed. The vertical surface is fixed on the aluminum substrate 14 and is attached to the back of the aluminum substrate 14 (by plugging or screw fixing). The movable key 22 is located at the end of the rod body.

[0056] The vertical plane in this embodiment ensures that the back of the light source assembly 1 is subjected to uniform force.

[0057] The other end of the slide key 22 is fixedly connected to the middle of the keycap 23. The keycap 23 is positioned above the first slide groove 110 and covers the first slide groove 110.

[0058] A first movable groove 110 is formed on the surface of the flashlight body 100, allowing the base of the movable key 22 to enter the flashlight body 100 and connect and fix it to the first metal part 21. The length of the first movable groove 110 is equal to the base of the movable key 22 plus the distance required for zooming, and it also limits the back-and-forth movement of the movable key 22. In this embodiment, the surface of the movable key 22 is slightly higher than the surface of the flashlight body 100, and the inner arc surface of the movable key 22 is consistent with the arc surface of the flashlight body 100. The movable key 22 can perfectly cover the surface of the flashlight body 100 and cover the first movable groove 110. Gently pushing the movable key 22 causes the first metal part 21 connected to it to transmit force to the back of the light source assembly 1, pushing the piston of the light source assembly 1 to move back and forth along the inner wall of the flashlight body 100. At the same time, the heat generated by the light source assembly 1 is conducted to the flashlight body 100. The first metal part 21 connected to the aluminum substrate 14 can also directly play a role in heat dissipation.

[0059] In addition, soft silicone strips 24 are provided on both sides below the movement key 22 to wrap around the base of the movement key 22.

[0060] like Figure 3 As shown, soft silicone strips 24 are added to both sides below the first moving groove 110, wrapping around the base of the moving key 22. This prevents moisture and dust from entering and also provides a non-slip function for the moving key 22. When using the moving key 22 to zoom, the thumb can be pressed and moved back and forth to easily adjust the aperture size. When the thumb is released, the moving key 22 will stop moving and remain in the position it was in when released. The flashlight switch can be located in front of or behind the moving key 22, based on the principle of not affecting the internal structure, easy grip, and comfortable operation of the moving key 22.

[0061] Example 2

[0062] See Figure 5 and Figure 6 As shown, the light source assembly 1 is cylindrical and includes an outer ring seat 11, an LED chip 12, a chip pressing component 13, and an aluminum substrate 14. The chip pressing component 13 and the aluminum substrate 14 are disposed on both sides of the LED chip 12, and the LED chip 12, the chip pressing component 13, and the aluminum substrate 14 are fixedly disposed on the axis of the outer ring seat 11.

[0063] The light source assembly 1 is very lightweight, generally not exceeding 20 grams, and its thickness is typically around 20 mm. External zoom flashlights also have a light source assembly 1, which is fixed to the inner wall of the lamp body via an outer ring seat 11 and cannot move. Unlike external zoom flashlights, the light source assembly 1 of this invention is separable from the inner wall of the lamp body. The outer diameter of the outer ring seat 11 is close to the inner diameter of the lamp body, and one or two grooves are cut on the side of the outer ring seat 11 for ventilation. This allows the light source assembly 1 to act like a piston, moving back and forth along the inner wall of the lamp body without deviation when driven. Simultaneously, the smoothness of this moving distance along the inner wall of the lamp body and the smoothness around the light source assembly 1 are ensured, and paraffin wax is sprayed for lubrication.

[0064] Unlike Embodiment 1, since the portable lamp has a larger power, the light source assembly 1 in this embodiment also includes a heat sink 27, which is disposed on the aluminum substrate 14.

[0065] In this embodiment, the lamp body is set as the body 200 of a portable lamp. A handle 210 is provided on the top of the body 200 of the portable lamp. The zoom component 2 includes a second metal part 25 and a push handle 26. One end of the second metal part 25 is connected to the heat sink 27 by bolts, and the other end of the second metal part 25 is fixedly connected to the push handle 26. The second metal part 25 extends from the inner cavity of the body 200 of the portable lamp to the handle 210, and the push handle 26 is located on the handle 210.

[0066] The portable lamp housing is provided with a handle 210, and a second moving groove 220 is opened on the handle 210. A second metal part 25 is disposed in the handle 210 and passes through the second moving groove 220. The inner cavity spacing of the handle 210 is used to limit the horizontal movement of the second metal part 25. The heat sink 27 is used for heat dissipation between the aluminum substrate 14 and the second metal part 25 (due to the large power of the portable lamp). The connection and fixation between the vertical surface of the second metal part and the heat sink 27 does not affect the movement and zoom of the light source assembly 1. When the push handle 26 is pushed, the light source assembly 1 can be moved horizontally in the portable lamp through the second metal part 25, thereby realizing the adjustment of the aperture size and aperture change.

[0067] Example 3

[0068] See Figure 7 and Figure 8 As shown, the light source assembly 1 is cylindrical and includes an outer ring seat 11, an LED chip 12, a chip pressing component 13, and an aluminum substrate 14. The chip pressing component 13 and the aluminum substrate 14 are disposed on both sides of the LED chip 12, and the LED chip 12, the chip pressing component 13, and the aluminum substrate 14 are fixedly disposed on the axis of the outer ring seat 11.

[0069] The light source assembly 1 is very lightweight, generally not exceeding 20 grams, and its thickness is typically around 20 mm. External zoom flashlights also have a light source assembly 1, which is fixed to the inner wall of the lamp body via an outer ring seat 11 and cannot move. Unlike external zoom flashlights, the light source assembly 1 of this invention is separable from the inner wall of the lamp body. The outer diameter of the outer ring seat 11 is close to the inner diameter of the lamp body, and one or two grooves are cut on the side of the outer ring seat 11 for ventilation. This allows the light source assembly 1 to act like a piston, moving back and forth along the inner wall of the lamp body without deviation when driven. Simultaneously, the smoothness of this moving distance along the inner wall of the lamp body and the smoothness around the light source assembly 1 are ensured, and paraffin wax is sprayed for lubrication.

[0070] Unlike Embodiment 1, since the handheld lamp has a higher power, the light source assembly 1 in this embodiment also includes a heat sink 27, which is disposed on the aluminum substrate 14.

[0071] In this embodiment, the lamp body is set as the body 300 of a handheld lamp. A handle 32 is provided below the body 300 of the handheld lamp. A buckle 33 is also provided between the handle 32 and the body 300 of the handheld lamp. The zoom assembly 2 includes a third metal part 28, a transition connecting block 29 and a buckle 31. The third metal part 28 is L-shaped and its side is detachably connected to the heat sink 27 through the transition connecting block 29. A buckle 31 is provided on its bottom side and is located inside the buckle 33.

[0072] The transition connection block 29 in this embodiment can improve the stability between the third metal part 28 and the heat sink 27.

[0073] In addition, an elastic element is provided between the handle 31 and the grip 32, and the elastic element in this embodiment is preferably a spring 34.

[0074] The third metal part 28 is also provided with a reinforcing rib 3. The two ends of the reinforcing rib 3 are fixed on the third metal part 28. The reinforcing rib 3 can ensure that the third metal part 28 will not deform.

[0075] When the third metal part 28, transition connecting block 29, reinforcing rib 3, buckle 31, handle 32, buckle ring 33 and spring 34 are installed on the handheld lamp, the handle 32 and buckle ring 33 are fixedly installed on the handheld lamp, the handheld lamp has a third moving groove 310, the buckle 31 slides in the third moving groove 310, when the buckle 31 is pulled, the buckle 31 moves horizontally in the third moving groove 310, compressing the spring 34, the buckle 31 causes the light source assembly 1 to move horizontally in the handheld lamp through the third metal part 28, transition connecting block 29 and heat sink 27, when the buckle 31 is stopped, the spring 34 extends and resets, the light source assembly 1 resets to the initial position, thereby realizing the adjustment of aperture size and aperture change.

[0076] Example 4

[0077] See Figure 9 and Figure 10 As shown, the light source assembly 1 is cylindrical and includes an outer ring seat 11, an LED chip 12, a chip pressing component 13, and an aluminum substrate 14. The chip pressing component 13 and the aluminum substrate 14 are disposed on both sides of the LED chip 12, and the LED chip 12, the chip pressing component 13, and the aluminum substrate 14 are fixedly disposed on the axis of the outer ring seat 11.

[0078] The light source assembly 1 is very lightweight, generally not exceeding 20 grams, and its thickness is typically around 20 mm. External zoom flashlights also have a light source assembly 1, which is fixed to the inner wall of the lamp body via an outer ring seat 11 and cannot move. Unlike external zoom flashlights, the light source assembly 1 of this invention is separable from the inner wall of the lamp body. The outer diameter of the outer ring seat 11 is close to the inner diameter of the lamp body, and one or two grooves are cut on the side of the outer ring seat 11 for ventilation. This allows the light source assembly 1 to act like a piston, moving back and forth along the inner wall of the lamp body without deviation when driven. Simultaneously, the smoothness of this moving distance along the inner wall of the lamp body and the smoothness around the light source assembly 1 are ensured, and paraffin wax is sprayed for lubrication.

[0079] like Figure 9a , Figure 9b and Figure 10 As shown, the lamp body is a headlamp body 400. The headlamp body 400 is equipped with a knob 37. The zoom assembly 2 includes a fourth metal part 35 and a gear 36. The fourth metal part 35 is L-shaped, and its vertical outer side is detachably connected to the heat sink 27. Its inner bottom is equipped with a rack. The gear 36 is meshed with the rack for transmission. The knob 37 is fixedly installed on one side of the gear 36. When the knob 37 is rotated, the fourth metal part 35 is moved through the gear 36.

[0080] When the fourth metal part 35, gear 36 and knob 37 are installed on the headlamp, the knob 37 can be manually rotated to make the gear 36 rotate. The gear 36 can drive the fourth metal part 35 to move horizontally inside the headlamp. The fourth metal part 35 can make the light source assembly 1 move horizontally synchronously inside the headlamp body 400, thereby realizing the adjustment of the aperture size and aperture change.

[0081] Examples 1-4 all involve internal zoom, meaning that the zoom is achieved by adjusting the distance between the light source assembly 1 inside the moving lamp housing and the fixed lens 120. The methods (means) described above, such as pushing with the movable key 22, pulling with a trigger, turning with the knob 37, and the internal light source of the moving lamp in electric mode, are all within the protection scope of this utility model.

[0082] The metal component connecting the light source assembly 1 and the movable key 22 described in Examples 1-4 is not the only material or style. The use of metal here is based on considerations of robustness, stability in force transmission, and heat dissipation. Other materials can also be used, and their styles are arbitrary. The connection methods between the metal component and the movable key 22 are diverse, ensuring ease of assembly and use.

[0083] The movable key 22 described in Examples 1-4 is not the only design. Alternatively, a groove can be made on the surface of the lamp housing so that the movable key 22 can move within the groove without protruding above the housing surface.

[0084] The piston-type light source assembly 1 described in Examples 1-4 can also have a track added to the inner wall of the lamp, or steel balls, needle rollers, etc., embedded on the outside of the light source assembly 1 to reduce the coefficient of friction and improve the sliding ability of the light source assembly 1. These changes, as well as other effective methods or means for moving the light source within the lamp, do not affect the protection of this utility model.

[0085] The internal zoom methods for several types of variable-focus lamps described in Examples 1-4 are not limited to other types of movable lamps and fixed lamps that use the above methods for internal zoom, and these are also within the protection scope of this utility model.

[0086] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0087] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.
