Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a lamp. Background Art

[0002] In occasions such as building exterior lighting decoration, stadiums, green belt lighting landscapes, residential areas, courtyard areas and billboards, different locations in the same occasion will have different lighting requirements. Taking a basketball court as an example, the ball rack requires higher light brightness than other locations.

[0003] To meet these requirements, existing technologies adjust the light angle of lamps at corresponding locations. There are two common approaches: one is to disassemble the lamp and replace lenses with different light-transmitting structures. The other is to install lenses with two light-transmitting structures. When light adjustment is needed, the glass panel of the lamp is disassembled, the position of the lens is adjusted, and different light-transmitting structures are replaced to correspond to the lamp beads. After completion, the glass panel is reinstalled. Both of these traditional methods require the removal and replacement of the glass panel, which is technically inefficient. Furthermore, the lamp needs to have reliable sealing, and the removal and replacement of the glass panel can easily result in the glass panel not being properly installed, causing the lamp to leak and fail.

[0004] With technological advancements, new existing technologies have also introduced movable and adjustable lenses within lamps. These lenses have at least two light-transmitting structures. By moving the lens to change the light-transmitting structure and align it with the light source, the light output of the lamp can be adjusted. Because these lenses are removably mounted within the lamp housing, they cannot be fixed with screws to prevent the central portion of the lens from buckling and deformation, as is done in conventional technologies. Therefore, preventing this type of lens from buckling and deformation due to heat presents a new technical challenge that needs to be addressed. Utility Model Content

[0005] The utility model provides a lamp, which is used to solve the technical problem that a movable lens in the lamp is easily heated, arched and deformed in the middle during use.

[0006] The utility model provides a lamp.

[0007] A lamp, comprising:

[0008] lamp housing;

[0009] A light source module is installed in the lamp housing and includes a substrate and light-emitting components distributed on the substrate;

[0010] a lens mounted in the lamp housing and located on the light emitting direction side of the light source module, the lens comprising a lens body and a raised support structure, the lens body having at least two different light-transmitting structures, the different light-transmitting structures having different light-emitting effects, the lens being movably mounted in the lamp housing so as to be able to replace different light-transmitting structures for alignment with the light-emitting element, the raised support structure being located on the side of the lens body on the light emitting direction side;

[0011] A light-transmitting panel is mounted at the light outlet of the lamp housing, and the raised support structure is used to cooperate with the top support of the light-transmitting panel to limit the deformation of the middle portion of the mirror body toward the light-transmitting panel.

[0012] In one technical solution, the raised support structure is a support column.

[0013] In one technical solution, the end of the support column that cooperates with the light-transmitting panel has a guiding slope surface, which is used to prevent the support column and the light-transmitting panel from getting stuck when the lens moves.

[0014] In a technical solution, a chamfered structure is formed between the end surface of the end portion of the support column that cooperates with the light-transmitting panel and the outer peripheral surface of the support column, and the chamfered structure constitutes the guide slope.

[0015] In one technical solution, the support column is a round rod-shaped structure with a diameter gradually decreasing along the light emitting direction.

[0016] In a technical solution, the light-transmitting structure forms a bulge on one side of the light-emitting direction of the mirror body and a depression on the other side, and the bulging direction of the bulge is consistent with the bulging direction of the bulge supporting structure.

[0017] In one technical solution, the lamp includes a plurality of the protruding support structures, and the plurality of the protruding support structures are arranged in a rectangular array on the mirror body.

[0018] In one technical solution, the mirror body is in the shape of a cuboid, and the row and column directions of the array of raised support structures are consistent with the length and width directions of the mirror body.

[0019] In one technical solution, the lens has a receiving groove on a surface facing the light source module, the receiving groove receives the light-emitting element, and the wall of the receiving groove opposite to the light source module has various light-transmitting structures.

[0020] In a technical solution, the lamp further includes a driving mechanism for driving the lens to move relative to the light source module so that different light-transmitting structures are aligned with the light-emitting element.

[0021] The beneficial effects of the utility model are:

[0022] According to the above-mentioned lamp, since the lens of the lamp in the utility model has at least two light-transmitting structures and can move in the lamp housing, the light-emitting effect of the lamp can be changed by moving the lens. For such a lens, the provided raised support structure cooperates with the top support of the light-transmitting panel. Without affecting the movement of the lens, the light-transmitting panel can be used to reversely limit the arching deformation of the middle part of the mirror body.

[0080] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0081] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0082] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0083] The lens of the lamp in the present invention has at least two light-transmitting structures and can move in the lamp housing, so that the light-emitting effect of the lamp can be changed by moving the lens. For such a movable lens in the lamp housing, a raised supporting structure is provided to cooperate with the top support of the light-transmitting panel. No matter how the lens changes its position, the raised supporting structure always cooperates with the top support of the light-transmitting panel. Without affecting the movement of the lens, the light-transmitting panel can be used to reversely limit the arching deformation of the middle part of the mirror body.

[0084] Embodiment 1 of the lamp in the present utility model:

[0085] Please refer to Figure 1 and Figure 2 The lamp includes a lamp housing 101, a light source module 102, a lens 103, and a translucent panel 104. Translucent panel 104 provides protection and transmits light. It can be glass or other transparent materials, such as acrylic. Lens 103 is located on the side of the light source module 102 that emits light. Translucent panel 104 is sealed against the light outlet of lamp housing 101. Lamp housing 101 serves as the lamp's heat sink, with cooling fins on its back.

[0086] Please refer to Figure 3 The light source module 102 includes a substrate 1021 and a light-emitting element. The substrate 1021 is a PCBA (printed circuit board). The light-emitting element is a lamp bead arranged on the substrate 1021. Every two lamp beads form a lamp bead unit. The two lamp beads that make up a lamp bead unit are a first lamp bead 1022 and a second lamp bead 1023. The two lamp beads have different color temperatures, one of which is 3000K and the other is 4000K. The lamp bead with one color temperature can be controlled to operate. Of course, those skilled in the art know that by arranging two lamp beads with different color temperatures in a lamp bead unit, the color temperature of the two lamp beads can be adaptively changed according to the application requirements of the lamp. Multiple lamp bead units are arranged in a rectangular array on the PCBA.

[0087] A plurality of light source mounting holes 1024 are arranged at intervals around the circumference of the substrate 1021. Figure 4 The bottom surface of the lamp housing 101 has a corresponding light source fixing hole 1011, which is a threaded blind hole, and the light source mounting hole 1024 is a countersunk hole. The light source module 102 can be fixed in the inner cavity of the lamp housing 101 by inserting a screw into the light source mounting hole 1024 and tightening the screw in the light source fixing hole 1011.

[0088] Please refer to Figure 4The bottom surface of the lamp housing 101 has a lens mounting structure for translatably mounting the lens 103. The lens mounting structure includes two rows of lens guide rails 1012, each having a supporting bottom wall 10121 and limiting side walls 10122. The lens 103 is supported on the supporting bottom walls 10121 of the two rows of lens guide rails 1012, sliding along the supporting bottom walls 10121. The left and right sides of the lens 103 are limited by the limiting side walls 10122. The lens guide rails 1012 are segmented, with the spaces between the segments providing space for the lugs extending from the base plate 1021. The light source mounting holes 1024 are located on the lugs.

[0089] The movement direction of the lens 103 is defined as the adjustment direction, and the adjustment direction is the front-to-back direction. The bottom surface of the lamp housing 101 is also provided with front limit blocks 1013 and rear limit blocks 1014 at intervals along the adjustment direction to prevent the lens 103 from moving too much in the adjustment direction. In order to prevent the lens 103 from being dislodged from the installation position along the light emitting direction, the bottom surface of the lamp housing 101 is also provided with a fixing column 1015. The center of the fixing column 1015 has a threaded hole. The fixing column 1015 is fixed to the upper end surface of the fixing column 1015 by screwing a screw into the threaded hole. Figure 8 The lens block 1016 in the middle blocks and limits the lens 103 along the light emitting direction.

[0090] For the structure of lens 103, please refer to Figure 5 and Figure 6 The lens 103 includes a lens body 1031 and a support column 1032. The lens body 1031 has two light-transmitting structures, namely a first light-transmitting structure 10311 and a second light-transmitting structure 10312. Both light-transmitting structures form a convexity on one side of the lens body 1031 in the light-emitting direction and a concaveity on the other side. However, the two light-transmitting structures are of different sizes, resulting in two different light-transmitting effects. Light emitted from the same light source has different optical angles after passing through these two light-transmitting structures, which can form different lighting effects.

[0091] Multiple first light-transmitting structures 10311 are arranged in a rectangular array, and multiple second light-transmitting structures 10312 are also arranged in a rectangular array. The first light-transmitting structures 10311 and the second light-transmitting structures 10312 are alternately arranged along the adjustment direction. Adjacent first light-transmitting structures 10311 and second light-transmitting structures 10312 form a group. The surface of the lens 103 facing the light source module 102 has multiple receiving grooves 10313 arranged in a rectangular array. A group of first light-transmitting structures 10311 and second light-transmitting structures 10312 is formed on the wall of the receiving groove 10313 opposite the light source module 102.

[0092] After assembly, each lamp unit is housed one-to-one within its corresponding receiving groove 10313. The two lamp units are arranged side by side in a direction perpendicular to the direction in which the first light-transmitting structure 10311 and the second light-transmitting structure 10312 are arranged side by side. The circumferential walls of the receiving groove 10313 can block and focus light.

[0093] The support column 1032 is located on the side of the mirror body 1031 on the light-emitting side. The connection between the two can be integrally formed, heat-fused, or screwed. The direction in which the support column 1032 protrudes relative to the mirror body 1031 aligns with the direction in which the protrusions of the light-transmitting structures protrude. After the lamp is assembled, the end of the support column abuts against the light-transmitting panel 104, which restrains the mirror body 1031 with the help of the light-transmitting panel 104, preventing the middle portion of the mirror body 1031 from arching toward the light-transmitting panel 104.

[0094] In one embodiment, please refer to Figure 7 The support column 1032 is a cylindrical structure with a diameter that gradually decreases along the light-emitting direction, and the end that mates with the light-transmitting panel 104 has a smaller diameter. This prevents stress concentration at the base of the support column, which could lead to breakage, when the lens 103 moves. In other embodiments, the support column could also be a cylinder with a constant diameter, or a support column with a cross-shaped cross-section, or a multi-sided pyramid structure.

[0095] In order to prevent the support column 1032 from getting stuck with the light-transmitting panel 104 when the lens 103 moves, a guiding slope is provided between the end face and the peripheral surface of the support column 1032. Figure 7 The guiding slope is a rounded corner structure 10321 between the end face and the peripheral surface of the support column 1032, specifically a fully rounded corner design. This design can also reduce the friction between the support column and the light-transmitting panel. In other embodiments, the guiding slope can also be an inclined plane that transitions between the end face and the peripheral surface of the support column.

[0096] To provide uniform support, the lens 103 has four support columns 1032 arranged in a rectangular array. The lens body 1031 is a rectangular plate structure of a certain thickness. The rows and columns of the rectangular array are aligned with the length and width of the lens body 1031. In other embodiments, the number of support columns can be adaptively increased or decreased. As those skilled in the art will appreciate, the arrangement of the support columns on the lens body can also be adaptively changed as long as the requirements for preventing arching and deformation are met.

[0097] The support column 1032 serves as a raised support structure, which, with the aid of the light-transmitting panel 104, prevents the mirror body 1031 from arching and deforming in the middle. In other embodiments, the raised support structure can also be in the form of a hollowed-out arch bridge, or a mushroom-shaped structure with a rod-shaped center and a ball-shaped end. For details on the distribution of the support column 1032, please refer to the distribution of the support column 1032.

[0098] Please refer to Figure 8 In order to drive the lens 103 to move and adjust the position, the lamp is also provided with a driving mechanism 105. The structure of the driving mechanism 105 is shown in FIG. Figure 9 and Figure 10 The driving mechanism 105 includes a slide 1051 and a slider 1052 installed in the slide 1051. The slide 1051 extends along the adjustment direction as a slide rail, and the slider 1052 moves along the adjustment direction under the constraint and guidance of the slide 1051. Figure 11 , including a bottom wall 10511, two side walls 10512, and a rear stop wall 10513 located at one end away from the lens 103. The rear stop wall 10513 serves as a stop structure to determine the limit position of the backward movement of the slider 1052. In other embodiments, the slide rail can also be a round rod, the slider is installed on the round rod, and the stop structure can be part of the lamp housing.

[0099] The end of each side wall 10512 close to the rear retaining wall 10513 has a first lug 10514, and a mounting hole is provided on the first lug 10514. The rear side surface of the first lug 10514 is flush with the rear side surface of the rear retaining wall 10513. The slide groove 1051 can be fixed in the lamp housing 101 by inserting screws into the mounting holes and tightening them with the threaded holes on the lamp housing 101.

[0100] The middle position of each of the two side walls 10512 is provided with a second lug 10515, and the second lug 10515 is provided with a fixing hole, which is a threaded hole for fixing Figure 12 The cover plate 1053 shown in the figure has two third lugs 10531 on both sides of the cover plate 1053. The third lugs 10531 are provided with mounting holes that match the fixing holes. By inserting screws into the mounting holes and tightening them in the fixing holes, the cover plate 1053 can be fixed on the slide groove 1051, and the notch on the upper side of the slide groove 1051 can be sealed.

[0101] Please refer to the structure of slider 1052 Figure 13The cover 1053 has a rectangular block structure with an upper side perpendicular to the light-emitting direction. An operating rod 10521 is connected to the end face away from the lens 103. The rear retaining wall 10513 of the slide 1051 has a first avoidance groove 105131 for avoiding the operating rod 10521. Correspondingly, an opening 1017 is provided in the lamp housing 101 for the operating rod 10521 to extend out. A first protrusion 10532 is provided on the inner sidewall of the corresponding end of the cover 1053. The end face of the first protrusion 10532 has an arcuate groove. After assembly, the first protrusion 10532 is inserted into the first avoidance groove 105131. The arcuate groove cooperates with the bottom portion of the first avoidance groove 105131 to constrain and guide the operating rod 10521. The operating rod 10521 serves as a manual operating unit for manual operation.

[0102] The driving mechanism also includes an elastic reset member that applies force to the slider 1052 to reset the slider 1052. In one embodiment, the elastic reset member is a reset spring 1054 that presses the slider 1052 against the rear retaining wall 10513. In order to install the reset spring 1054, the front notch of the slide groove 1051 is covered with a Figure 14 End cap 1055 shown, please refer to Figure 11 The outer sides of the two side walls 10512 of the chute 1051, facing away from the rear retaining wall 10513, each have a fourth lug 10516. These lugs 10516 have threaded fixing holes. Correspondingly, the end cap 1055 has mounting holes that mate with these holes. Screws are inserted through the mounting holes and tightened into the holes to secure the end cap 1055 to the end of the chute 1051. The side of the end cap 1055 facing the inside of the chute 1051 has two bosses 10551. During assembly, one end of the two return springs 1054 is fitted over the bosses 10551. Correspondingly, the end surface of the slider 1052 facing the end cap 1055 has an insertion hole 10522 for the other end of the return spring 1054. After the operating force is removed, the slider 1052 remains pressed against the rear retaining wall 10513, pushed by the return spring 1054. In other embodiments, the elastic return member may also be a tension spring connected between the slider and the sliding groove.

[0103] Please refer to Figure 15 The upper side of the slider 1052 has an annular groove. The annular groove includes a first V-shaped groove section 10523 close to the lens 103 and a second V-shaped groove section 10524 further away from the lens 103. The V-shaped openings of the first V-shaped groove section 10523 and the second V-shaped groove section 10524 both face away from the lens 103. The groove sections between the first V-shaped groove section 10523 and the second V-shaped groove section 10524 are an inlet groove section 10525 and a outlet groove section 10526, respectively. The bend of the first V-shaped groove section 10523 serves as a first locking position 10527, and the bend of the second V-shaped groove section 10524 serves as a second locking position 10528.

[0104] The driving mechanism 105 further comprises a connecting structure connecting the slider 1052 and the lens 103, please refer to Figure 8 、 Figure 16 and Figure 17 The connecting structure comprises a pull hook 106 and a connecting rod 107, the connecting rod 107 is T-shaped, the horizontal rod segment 1071 is connected with the lens 103, and the end of the vertical rod segment 1072 has a connecting hole 1073 extending in the light emitting direction. The pull hook 106 is a U-shaped structure with a folding arm, one end of the folding arm is a connecting arm 1061 which is inserted into the connecting hole 1073 and can rotate in the connecting hole 1073, and the other end of the folding arm is a hook portion 1062 which is hooked in the annular groove and can slide in the annular groove. In order to avoid the connecting rod 107, a second avoiding groove 10556 is formed on the end cover 1055, and the connecting rod 107 extends to the sliding groove through the second avoiding groove 10556. The cover plate 1053 further has a second protrusion 10533, and the end surface of the second protrusion 10533 has an arc-shaped groove. After assembly, the second protrusion 10533 is inserted into the second avoiding groove 10552, and the arc-shaped groove is partially matched with the groove bottom of the second avoiding groove 10552 to constrain and guide the connecting rod 107.

[0105] In other embodiments, the pull hook 106 can also be fixedly connected with the connecting rod 107, and the pull hook 106 is made of a material with a certain elasticity. By deforming the pull hook 106, it is ensured that the hook portion can slide in the sliding groove. Of course, the pull hook can also be directly connected with the lens.

[0106] The slider 1052 and the cover plate 1053 are arranged in a spaced manner, and the pull hook 106 enters the annular groove through the space between the slider 1052 and the cover plate 1053. In this way, the pull hook 106 can be prevented from coming out of the annular groove by the constraint of the cover plate 1053. The slider 1052 has two protrusions 105220 arranged on the upper side and located on both sides of the annular groove, and the protrusions 105220 are in sliding cooperation with the cover plate 1053.

[0107] When the hook portion 1062 is hooked in the first locking position 10527, the lens 103 is located in the first working position, and the first light transmission structure 10311 is aligned with the lamp bead unit. When the hook portion 1062 is hooked in the second locking position 10528, the lens 103 is located in the second working position, and the second light transmission structure 10312 is aligned with the lamp bead unit.

[0108] The slider 1052 and the operating rod 10521 form a pressing member. When operating, the operating rod 10521 is pressed by hand. In order to enable the hook portion 1062 to be cyclically positioned between the first locking position 10527 and the second locking position 10528 when the pressing member is repeatedly pressed, so that the lens 103 is cyclically positioned between the first working position and the second working position, the first inner groove wall inflection point 10529 of the first V-shaped groove segment 10523 is closer to the return groove segment 10526 than the first outer groove wall inflection point 105210, and the groove entry segment 10525 is offset from the second V-groove. The second outer groove wall inflection point 105211 at the transition point between section 10524 is offset closer to the return groove section 10526 than the second inner groove wall inflection point 105212, the third outer groove wall inflection point 105213 of the second V-shaped groove section 10524 is offset closer to the entry groove section 10525 than the third inner groove wall inflection point 105214, and the fourth inner groove wall inflection point 105215 at the transition point between the return groove section 10526 and the second V-shaped groove section 10524 is offset closer to the entry groove section 10525 than the fourth outer groove wall inflection point 105216.

[0109] To achieve the above-mentioned inflection point offset, in one embodiment, a first locking position guide edge 105217 is formed at the inflection point of the inner groove wall of the first V-shaped groove segment 10523, and the first locking position guide edge 105217 forms an effect of cutting off part of the groove wall at the inflection point, so that the first inner groove wall inflection point 10529 of the first V-shaped groove segment 10523 is closer to the return groove segment 10526 than the first outer groove wall inflection point 105210. In this way, when the pressing member is pressed, the hook portion 1062 initially located in the first locking position 10527 (at this time the lens 103 is in the first working position) can contact the first locking position guide edge 105237, and enter the groove entry section 10525 under the guidance of the first locking position guide edge 105237, and along the groove entry section 10525 reach the connection transition position between the groove entry section 10525 and the second V-shaped groove section 10524.

[0110] An outer guide edge 105218 is formed on the outer groove wall at the transition position between the groove entry section 10525 and the second V-shaped groove section 10524. The outer guide edge 105218 is connected to the outer groove wall 105219 of the second V-shaped groove section 10524 to form an inflection point. The inflection point constitutes the second outer groove wall inflection point 105211 at the transition position between the groove entry section 10525 and the second V-shaped groove section 10524, which is offset closer to the return groove section 10526 than the second inner groove wall inflection point 105212. After pressing the push piece to the extreme position, the hook 1062 reaches the inflection point 105211 of the second outer groove wall. After releasing the push piece, the slider 1052 is reset under the push of the reset spring 1054, and the hook 1062 contacts the inner groove wall of the second V-shaped groove section 10524 and finally enters the second locking position 10528. As the slider 1052 continues to reset under the push of the reset spring 1054, the slider 1052 pulls the lens 103 to the second working position through the pull hook 106.

[0111] When the push member is pressed again, the hook portion 1062 first slides from the second locking position 10528 to the fourth outer groove wall inflection point 105216. As the push member continues to move, it pushes the lens 103 toward the first working position via the hook 106. When the slider 1052 is reset, because the fourth inner groove wall inflection point 105215 is offset closer to the groove entry section 10525 than the fourth outer groove wall inflection point 105216, the hook portion 1062 can enter the groove return section 10526 and finally reach the first locking position 10527.

[0112] In other embodiments, the lens 103 may be fixed in the lamp housing 101 , and the light source module 102 may be movable in the lamp housing 101 as a movable part. The driving mechanism is connected to the light source module 102 to drive the light source module 102 to change its position.

[0113] To ensure a waterproof seal, the lamp also includes a waterproof cap 108 that seals over opening 1017. Specifically, waterproof cap 108 is screwed to lamp housing 101, with a sealing ring pressed between it and the lamp housing 101. Waterproof cap 108 covers the manual operating portion of the drive mechanism. In other embodiments, a sliding seal may be provided between operating lever 10521 and opening 1017 to ensure a waterproof seal. Of course, if the lamp is used indoors and does not require waterproofing, a waterproof seal may not be required for opening 1017.

[0114] As for the driving mechanism, in other embodiments, it can also be a press-driven driving mechanism with other structural forms, such as a driving mechanism for driving the refill of an automatic ballpoint pen to extend and retract, or a driving mechanism with a cabinet door rebounder structure.

[0115] Embodiment 2 of the lamp in the present utility model:

[0116] The main difference between this embodiment and embodiment 1 and the other embodiments described above is the structure of the lens and the structure of the driving mechanism. The other structures are similar to those of embodiment 1 and the other embodiments described above.

[0117] Please refer to Figure 18 The surface of the lens 203 in the light emitting direction is defined as the light emitting surface 2031, and the circumferential surface adjacent to the light emitting surface 2031 is defined as the side surface 2032. The left and right side surfaces of the lens 203 each have three groups of positioning grooves, and each group of positioning grooves includes two V-shaped positioning grooves 2033 arranged in parallel along the adjustment direction.

[0118] The structure of the lamp housing 201 is as follows Figure 19 and Figure 20 As shown, each set of positioning grooves is fixed in the lamp housing 201 as shown. Figure 21 The elastic positioning member 204 shown includes a mounting portion 2041 having a first mounting hole 20411 defined therein. Correspondingly, a fixing hole 2011 corresponding to the first mounting hole is defined on the bottom wall of the lamp housing 201. The fixing hole 2011 is a threaded hole. By inserting a screw into the first mounting hole 20411 and tightening it within the fixing hole 2011, the elastic positioning member 204 can be fixedly mounted on the bottom wall of the lamp housing 201. The elastic positioning member 204 also has a locking portion 2042, which is a V-shaped spring structure. The locking portion 2042 is embedded in the V-shaped positioning groove 2033 to constrain the position of the lens 203. When the lens 203 is moved, the inclined surface of the V-shaped structure acts as a guide surface, allowing the lens 203 to overcome the elastic force of the locking portion 2042, allowing the locking portion 2042 to be ejected from the V-shaped positioning groove 2033, ensuring that the lens 203 can be driven to move and adjust its position. In other embodiments, the positioning groove can also be a hemispherical groove, and correspondingly, the locking portion is a spring with a circular protrusion. In this case, the guide surface is a hemispherical structure. The lens guide rail 1012 is a segmented structure to avoid the light source module and the elastic positioning member 204.

[0119] In order to prevent the lens 203 from being disengaged from the installation position along the light emitting direction, the elastic positioning member 204 further has an elastic pressing piece 2043 that cooperates with the light emitting surface 2031 of the lens 203 .

[0120] In one embodiment, please refer to Figure 18 , each group of positioning grooves includes two positioning grooves. In other embodiments, the lens can have three different light-transmitting structures. Correspondingly, each group of positioning grooves includes three positioning grooves, so that the lens has three working positions. Of course, as a person skilled in the art, it can be understood that based on the basic concept of the present invention, there can be more types of light-transmitting structures on the lens, and the number of positioning grooves in each group of positioning grooves corresponds to it, so as to realize the adjustment of the lens in different working positions.

[0121] The driving mechanism includes Figure 22 The push-pull rod 202 shown is a T-shaped structure. The horizontal rod section 2021 of the T-shaped push-pull rod 202 is connected to the lens 203. One end of the vertical rod section 2022 extends out of the lamp housing 201 through the opening 2012 to form a manual operation part for manual operation. In order to ensure the waterproof effect of the lamp, please refer to Figure 23 The lamp also has a waterproof cap 205 with a sealing cover installed at the opening 2012. The opening 2012 has an internal thread. The waterproof cap 205 is screwed onto the opening 2012 through a threaded structure, and a sealing ring is pressed between the waterproof cap 205 and the wall of the opening 2012.

[0122] The lamp also has a positioning guide structure for positioning and guiding the push-pull rod 202. The positioning guide structure includes Figure 24 and 25 The support base 206 and pressure cover 207 shown in the figure, the support base 206 is in the shape of a "几", and the lower ends of the two legs have folded edges, and each folded edge is provided with a mounting hole. Correspondingly, there are fixing holes corresponding to the mounting holes on the bottom of the lamp housing 201, and the fixing holes are threaded holes. By inserting screws into the mounting holes and tightening them into the fixing holes, the support base 206 can be fixedly installed in the lamp housing 201. The top surface of the support base 201 has a first positioning groove 2061 extending along the adjustment direction, and the pressure cover 207 is fixed to the support base 206 by screws. The surface of the pressure cover 207 facing the support base 206 has a second positioning groove 2071 extending along the adjustment direction. After the pressure cover 207 is installed on the support base 206, the first positioning groove 2061 and the second positioning groove 2071 form a guide groove, and the vertical rod section 2022 of the push-pull rod 202 is inserted into the guide groove.

[0123] The lens 203 is used as a movable part. When the lamp is used, the position of the lens 203 can be adjusted by operating the push-pull rod 202. In other embodiments, the light source module can also be used as a movable part, and the push-pull rod is connected to the light source module.

[0124] Embodiment 3 of the lamp in the present utility model:

[0125] The main difference between this embodiment and embodiment 1 and the other embodiments described above is the structure of the lens and the structure of the driving mechanism. The other structures are similar to those of embodiment 1 and the other embodiments described above.

[0126] In this embodiment, please refer to Figure 26 The bottom wall of the lamp housing 301 has a through hole structure 3011 that passes through the bottom wall. The driving mechanism includes Figure 27 The driving shaft 302 shown in the figure is arranged in the through hole structure 3011. The end of the driving shaft 302 located inside the lamp housing 301 has a cam 303. The end of the driving shaft 302 located outside the lamp housing 301 is connected to the cam 303. Figure 28 The operating handle 304 in the shape of the middle is fixed and connected. The operating handle 304 is used as a manual operating part for the operator to operate. By operating the operating handle 304, the cam 303 can be driven to rotate. Please refer to Figure 29 The cam 303 is in contact with the rear end surface of the lens 305 , and when the cam 303 rotates, the lens 305 can be driven to move forward.

[0127] Please refer to Figure 30 The through-hole structure 3011 has a positioning protrusion 3012 on the edge of the outer opening. Correspondingly, the operating handle 304 has two positioning and mating protrusions 3041. When one of the positioning and mating protrusions 3041 contacts and stops one side of the positioning protrusion 3012, the lens 305 is in one working position, and one structure of the light-transmitting structure on the lens 305 is aligned with the lamp unit. When the operating handle 304 is rotated until the other positioning and mating protrusion 3041 contacts and stops the other side of the positioning protrusion 3012, the lens 305 moves to the other working position, at which point the other structure of the light-transmitting structure on the lens 305 is aligned with the lamp unit. The operating handle 304 is marked with text indicating the corresponding state.

[0128] In order to make the lens 305 return to its original position, the driving mechanism also includes Figure 31 The elastic pushing mechanism shown in FIG3 comprises a mounting base 3061, a push rod 3062, a compression spring 3063 and a baffle 3064. The mounting base 3061 has a notch structure 30611 at the bottom so that the mounting base 3061 can be fixed in the lamp housing 301 by inserting screws in the notch structure 30611. The mounting base 3061 also has a telescopic hole 30612 extending along the adjustment direction. The hole wall of the telescopic hole 30612 has a guide groove 30613. The guide groove 30613 radially penetrates the hole wall of the telescopic hole 30612 and penetrates the hole wall of the telescopic hole 30612 forward. The push rod 3062 is arranged in the telescopic hole 30612, and the outer peripheral surface of the push rod 3072 has a guide block 30621 that cooperates with the guide groove 30613. The push rod 3062 comprises a large-diameter section at the front and a small-diameter section at the rear. The small-diameter section connects to the large-diameter section at a position slightly below the rear end face of the large-diameter section. The small-diameter section is designed to abut against the front end face of the lens 305. A guide block 30621 is located on the large-diameter section. A blind hole is defined at the center of the large-diameter section. One end of a compression spring 3063 is inserted into the blind hole. A baffle 3064 is fixed to the front end face of the mounting base 3061. The baffle 3064 has a spring mounting post 30641. The other end of the compression spring 3063 is sleeved on the spring mounting post 30641 and abuts against the baffle 3064. When the lens 305 is in the first working position, the compression spring 3063 is compressed. When the cam rotates in the opposite direction, the compression spring 3063, via the push rod 3062, pushes the lens 305 to the second working position.

[0129] In other embodiments, mounting posts with cantilevered front and rear ends can be formed within the lamp housing, with a compression spring mounted on the posts. Specifically, the front end of the compression spring fits over the posts and abuts against the inner wall of the lamp housing, while the rear end pushes against the lens. Lens 305 acts as a movable part, and the light output effect of the lamp can be adjusted by changing the position of the lens. In other embodiments, the light source module can also serve as a movable part.

[0130] The lamps also include Figure 32 The elastic positioning member 307 shown in the figure includes a mounting portion 3071, a second mounting hole 30711 is provided on the mounting portion 3071, and correspondingly, a fixing hole 3013 corresponding to the second mounting hole is provided on the bottom wall of the lamp housing 301. The fixing hole 3013 is a threaded hole. By inserting a screw into the second mounting hole and tightening it in the fixing hole 3013, the elastic positioning member 307 can be fixed to the bottom wall of the lamp housing 301. The elastic positioning member 307 also has a locking portion 3072. The locking portion 3072 is a spring structure with a downwardly protruding circular protrusion 30721. Correspondingly, please refer to Figure 33 There is a locking groove group on the side of the lens 305 in the light-emitting direction, which includes two circular grooves 3051 arranged at intervals along the adjustment direction. When the lens 305 is in different working positions, the circular protrusion 30721 corresponds to the circular groove 3051 to position the lens 305.

[0131] When the lens 305 is moved, the hemispherical surfaces of the circular protrusion 30721 and the circular groove 3051 serve as guiding surfaces, so that the lens 305 can overcome the elastic force of the locking portion 3072, so that the circular protrusion 30721 can be pushed out of the circular groove 3051, ensuring that the lens 305 can be driven to move and adjust the position.

[0132] In other embodiments, the locking groove group on the side of the lens 307 in the light-emitting direction can be composed of V-shaped locking grooves, and the corresponding locking portion on the elastic positioning member is a V-shaped locking portion, which is embedded in the corresponding V-shaped locking groove to position the lens 305. In this structure, the guiding surface is a V-shaped inclined surface.

[0133] To ensure the waterproof sealing performance of the lamp, please refer to Figure 34 The lamp also has a waterproof cap 308, which is threadedly mounted on the lamp housing and has a sealing ring pressed between the waterproof cap 308 and the lamp housing. The waterproof cap 308 covers the operating handle 304 therein.

[0134] In the above embodiments, only the lens or the light source module is a movable piece, and in other embodiments, the lens and the light source module can be movably installed in the lamp housing, and both the lens and the light source module are movable pieces, so that the adjustment movement of the movable pieces is halved. The movement of the movable piece can also be rotation. Taking the lens as an example, the light transmission structures of different structures are arranged side by side in the circumferential direction of the lens. By rotating the lens, the light transmission structures of different structures on the lens can be aligned with the light emitting piece.

[0135] The above application of specific examples is used to illustrate the present application, which is only used to help understand the present application and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, transformations or substitutions can be made.
