[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0058] like Figure 1-5As shown, the present application relates to an angle-adjustable structure and an LED wall lamp. The angle-adjustable structure includes: a lamp body shell 10; the lamp body shell 10 refers to the surface shell of the lamp body, which can achieve a good protection effect and also has an aesthetic effect; in the present application, the lamp body shell 10 is in a triangular shape, which can achieve a good coordination effect with other components, thereby ensuring a good brightness presentation effect. Of course, in order to adapt to a variety of usage environments, the shape of the lamp body shell 10 can be formulated according to actual usage requirements, which is not limited in the present application. Preferably, the material of the lamp body shell 10 includes but is not limited to: plastic, aluminum alloy or glass.
[0059] The heat dissipation component 20 is disposed in the lamp body shell 10, and is an important component that can achieve a good heat conduction effect, thereby ensuring the normal operation of light sources such as LEDs and extending their service life. In the present application, the heat dissipation component 20 is an independent radiator, and the heat dissipation performance can be improved by adopting the form of an independent radiator. Preferably, a plurality of heat dissipation fins are arranged at intervals on the heat dissipation component 20, which can ensure a good heat dissipation effect.
[0060] The first connecting member 30 is at least partially connected to one end of the heat dissipation component 20 along the first direction; the first connecting member 30 is a shaft screw, through which the lamp body shell 10 is connected to one end of the heat dissipation component 20, and the two are in a rotatable state. A limited locking seat is provided at one end of the heat dissipation component 20, which can achieve a good matching effect with the first connecting member 30, and at the same time, it can also achieve the effect of facilitating the adjustment of the length. At the same time, in order to prevent the end of the first connecting member 30 from overtravel, a limit block is also provided on the heat dissipation component 20, which can achieve the effect of abutting against the end of the first connecting member 30. Among them, the first direction refers to the horizontal direction, which is also the X-axis direction in the two coordinate systems.
[0061] The limiting rotating member 40 is arranged cocentrically with the first connecting member 30 along the first direction and is connected to one end of the heat dissipation component 20 away from the connecting member; the limiting rotating member 40 refers to a turntable member, which can achieve good limiting and angle rotation effects; by assembling the limiting rotating member 40 at one end of the heat dissipation component 20, a precise angle adjustment effect can be achieved; at the same time, the limiting rotating member 40 and the first connecting member 30 are arranged cocentrically, which can ensure a good transmission effect, thereby ensuring that the lamp is in a good state.
[0062] Preferably, the outer surface of the limit rotating member 40 is provided with an inner hexagonal groove, so as to achieve a good matching effect with external components, thereby ensuring a good force application effect.
[0063] The gear member 50 is sleeved on the limit rotating member 40, and one side thereof is meshed and connected with the limit rotating member 40; it can achieve a good assembly effect with the limit rotating member 40, thereby achieving a precise angle limiting effect; at the same time, due to the use of meshing matching, it can achieve a plurality of angle adjustable effects.
[0064] The elastic component 60 is sleeved on the position-limiting rotating member 40 and is disposed against the gear member 50 on the side away from the position-limiting rotating member 40; by providing the elastic component 60, a good position-limiting and fixing effect on the gear member 50 can be achieved, thereby ensuring that the gear member 50 is in a stable state, and further ensuring that the heat dissipation component 20 does not move abnormally. In the present application, the elastic component 60 is a spring, which can provide a good elastic effect.
[0065] The second connecting member 70 is embedded in the limiting rotating member 40 and is at least partially connected to one end of the heat dissipation member 20; the second connecting member 70 is a turntable fixing screw. By providing the turntable fixing screw, it is possible to achieve the effect of fixing and assembling multiple components, thereby ensuring a stable connection between the components.
[0066] Among them, one end of the heat dissipation component 20 cooperates with the lamp body shell 10 through the first connecting member 30 to form a non-interlocking fixed structure, and the other end of the heat dissipation component 20 cooperates with the lamp body shell 10 through the limiting rotating member 40, the gear member 50, the elastic member 60 and the second connecting member 70 to form an interlocking fixed structure.
[0067] Specifically, the shaft screw is fixed to one end of the independent heat sink, and the shaft fixing plate and the shaft fixing plate fixing screw are fixed to the inside of the lamp body shell 10 in a non-embedded manner. This ensures that one end of the heat dissipation component 20 is well connected to the lamp body shell 10, and at the same time, it ensures that the heat dissipation component 20 is movable and can rotate with it.
[0068] The turntable fixing screw passes through the turntable fixing screw waterproof ring, the turntable, the turntable waterproof ring, the gear part 50, the compression spring, and passes through the lamp body shell 10 to form an interlocking fixation with the independent heat sink. A good assembly effect of the heat dissipation component 20 and the lamp body shell 10 can be achieved, thereby providing a basis for precise angle adjustment.
[0069] From the above description, it can be seen that the present application achieves the following technical effects:
[0070] In the embodiment of the present application, an angle-adjustable manner is adopted, whereby one end of the heat dissipation component 20 cooperates with the lamp body shell 10 through the first connecting member 30 to form a non-embedded fixed structure, and the other end of the heat dissipation component 20 cooperates with the lamp body shell 10 through the limiting rotating member 40, the gear member 50, the elastic member 60 and the second connecting member 70 to form an embedded fixed structure, thereby achieving the purpose of adjusting the angle of the heat dissipation component 20, thereby achieving the technical effect of accurately adjusting the angle structure of the internal structure of the connecting shaft and improving the service life of the lamp, thereby solving the problem that the traditional wall lamp is installed on the wall in a conventional fixed angle manner, and the lighting distance and range are single. Although some existing lamps on the market have an angle-adjustable function, they use changes in the external structure to achieve the angle adjustment requirement, and have poor adjustment accuracy, cannot meet the lighting requirements in different situations, and affect the appearance of the lamp.
[0071] like Figure 10-12 As shown, the inner wall of the position-limiting rotating member 40 is evenly provided with a plurality of first gears 401 along the circumferential direction thereof, and the plurality of first gears 401 are respectively meshed and connected with a plurality of second gears 501 evenly provided on the gear member 50 along the circumferential direction;
[0072] Among them, by adjusting the limit rotating member 40 to a preset position, the limit rotating member 40 drives the heat dissipation component 20 to rotate to a corresponding specified position, and the adjusted angle of the heat dissipation component 20 is fixed by the engagement of the second gear 501 with the first gear 401, and the second gear 501 is limited and fixed by the elastic component 60. It can be understood that, by respectively providing a plurality of first gears 401 on the limit rotating member 40 and a plurality of second gears 501 on the gear member 50, and meshing the first gears 401 and the second gears 501 to be connected, when adjusting the angle of the limit rotating member 40, the first gear 401 on the limit rotating member 40 rotates together, so that the positions of the first gear 401 and the second gear 501 change, thereby driving the heat dissipation component 20 to rotate at an angle, and finally obtaining the required illumination angle; at the same time, because the second gear 501 meshes with the first gear 401, when the first gear 401 is at a preset angle, the second gear 501 limits and fixes the first gear 401 to keep it in the current state and angle, so as to avoid the situation of returning or resetting, thereby affecting the accuracy of adjusting the angle. And, to ensure that the second gear 501 is in a stable state, the elastic component 60 is respectively set against one end of the second gear 501 and the inner wall of the lamp body shell 10, so as to ensure that the second gear 501 is in a stable state, so as to prevent it from being in a state of being able to move at will.
[0073] Of course, in order to ensure good gear meshing effect, relevant data such as the gear module and number of teeth can be formulated according to actual usage requirements to obtain the required rotation angle.
[0074] Furthermore, a semi-open position-limiting recess 101 matching with the first connector 30 is provided on one side of the lamp body shell 10, and the position-limiting recess 101 includes: a first position-limiting recess 1011 and a second position-limiting recess 1012, and the first position-limiting recess 1011 and the second position-limiting recess 1012 respectively match with different parts of the first connector 30. It can be understood that by providing the position-limiting recess 101, a good position-limiting matching effect can be achieved, thereby ensuring a good matching effect with the first connector 30. Among them, the first position-limiting recess 1011 matches with the nut, and the second position-limiting recess 1012 matches with the stud.
[0075] Furthermore, the depth of the first limiting recess 1011 is greater than the depth of the second limiting recess 1012. It can be understood that a good matching effect can be ensured, so that interference is not avoided, thereby ensuring the limiting and rotatable effects of the first connecting member 30 in the limiting groove 1023.
[0076] Furthermore, the limiting concave portion 101 is provided with a limiting baffle 80 for limiting and fixing the first connecting member 30. It is understandable that by assembling the limiting baffle 80 on the limiting concave portion 101, the effect of limiting the degree of freedom of the first connecting member 30 can be achieved, so that the desired motion state can be obtained.
[0077] Of course, the limiting baffle 80 can be connected by fixing screws of the limiting baffle 80, so as to achieve the effect of easy disassembly and assembly. The limiting baffle 80 can be in the shape of a straight plate.
[0078] Preferably, the number of fixing screws of the limiting baffle 80 is two, which can ensure a stable assembly effect.
[0079] like Figure 6-7 As shown, a limiting hole 102 matching with the limiting rotating member 40 is provided on the side of the lamp body shell 10 away from the first connecting member 30. It can be understood that by providing the limiting hole 102 on the lamp body shell 10, a good assembly effect with the limiting rotating member 40 can be achieved.
[0080] Of course, another limiting hole 102 opposite to the limiting hole 102 can be added on the lamp body shell 10, and related components such as the limiting rotating part 40 can be added accordingly. At this time, the limiting hole 102 on the other side also has the function of adjustable angle, which will not be elaborated here.
[0081] Furthermore, a plurality of stepped steps 1021 are provided in the limiting hole 102. It is understandable that by setting the limiting hole 102 into the stepped steps 1021, a good assembly effect with the limiting rotating member 40 can be achieved, thereby ensuring the stability of the assembly. Among them, the diameter of the stepped steps 1021 increases from the inside to the outside, thereby ensuring a good fitting effect.
[0082] Further, an annular convex portion 1022 extending from the inside to the outside is provided at the bottom of the limiting hole 102, and the annular convex portion 1022 cooperates with one of the steps 1021 to form a limiting groove 1023. It can be understood that by providing the annular convex portion 1022 at the bottom of the limiting hole 102, and the annular convex portion 1022 cooperates with the step 1021 to enclose the limiting groove 1023 with one end open, a good limiting and fixing effect of the elastic component 60 can be achieved, thereby ensuring that it stably acts on one side of the gear member 50.
[0083] like Figure 13-14 As shown, the inner wall of the step 1021 is respectively provided with two first limiting clamping columns 1024 for limiting and fixing the limiting rotating member 40 and two second limiting clamping columns 1025 for limiting and fixing the gear member 50. It can be understood that by respectively providing the two first limiting clamping columns 1024 for limiting and fixing the limiting rotating member 40 and the two second limiting clamping columns 1025 for limiting and fixing the gear member 50 on the inner wall of one of the steps 1021 located in the middle, the limiting rotating member 40 and the gear member 50 can be limited and fixed respectively, so as to ensure that the limiting rotating member 40 rotates to the required angle, so as to avoid the situation of over-angle, thereby affecting the illumination or other situations.
[0084] The fan-shaped area formed between the two first limit clamping columns 1024 is the movable limit of the limit rotating member 40 , which is also the interval marked 0-45 in the figure; the two second limit clamping columns 1025 are the clamping point limits of the gear member 50 .
[0085] like Figure 8-9As shown, the heat dissipation component 20 is provided with a cross-shaped limiting protrusion 201 at least near one end of the limiting rotating member 40, and the limiting protrusion 201 is plugged into the bottom of the limiting rotating member 40. At least one positioning protrusion 2011 is also provided on the limiting protrusion 201, and the positioning protrusion 2011 is clamped with the positioning recess 402 opened at the bottom of the limiting rotating member 40. It can be understood that by providing a limiting protrusion 201 at one end of the heat dissipation component 20 close to the limiting rotating member 40, and at the same time, providing a hollow column matching the shape of the limiting protrusion 201 at the bottom of the limiting rotating member 40, a good plug-in effect between the hollow column and the limiting protrusion 201 can be achieved, thereby achieving a good fixing effect; and a positioning protrusion 2011 is provided on the limiting protrusion 201, which can achieve a good coordination effect with other components and a good positioning effect; the positioning protrusion 2011 is clamped with the positioning recess 402 provided on the limiting rotating member 40, so as to ensure a good positioning effect of the limiting component.
[0086] Furthermore, the outer surface of the limit rotating member 40 is provided with a marking arrow 403 corresponding to the positioning recess 402. It can be understood that by providing the marking arrow 403 on the outer surface of the limit assembly, the state of the limit rotating member 40 can be intuitively known, thereby achieving the effect of facilitating clear knowledge of the reset.
[0087] Preferably, the outer surface of the position-limiting rotating member 40 is also provided with a plurality of angle scales, wherein the angle scales include but are not limited to: 0°, 15°, 30° and 45°. By providing a marking arrow 403 on the rotating disk, and corresponding to the scale on the lamp body shell 10, the angle between the independent radiator and the horizontal plane can be displayed at this time.
[0088] For example, the following states: 1. When the scale pointer is horizontal, the luminous surface is vertically downward, and the scale mark is 0°;
[0089] 2. When the scale pointer is at a horizontal angle of 15°, the angle between the luminous surface and the vertical direction is 75°, and the scale mark is 15°;
[0090] 3. When the scale pointer is at a horizontal angle of 30°, the angle between the luminous surface and the vertical direction is 60°, and the scale mark is 30°;
[0091] 4. When the scale pointer is at a horizontal angle of 45°, the angle between the luminous surface and the vertical direction is 45°, and the scale mark is 45°.
[0092] Furthermore, the first waterproof ring 90 and the second waterproof ring 100 are respectively provided between the limit rotating member 40 and the second connecting member 70 and the lamp body shell 10. It can be understood that by respectively providing the first waterproof ring 90 and the second waterproof ring 100, the waterproof effect of multiple points can be achieved, thereby ensuring a good sealing effect, and then the service life of the lamp can be improved. Among them, the first waterproof ring 90 refers to the waterproof ring of the fixing screw of the turntable, and the second waterproof ring 100 refers to the waterproof ring of the turntable. The effect of waterproofing the corresponding position can be achieved.
[0093] The angle adjustment working principle of the utility model is as follows:
[0094] By meshing the limiting rotating member 40 and the gear member 50, the gear member 50 can be prevented from rotating or moving in the horizontal direction, and at the same time, the gear member 50 compresses the spring to form an assembly; when the turntable member rotates under the action of a certain external force, the first gear 401 of the turntable member and the second gear 501 of the gear member 50 are subjected to force, forcibly compressing the spring, so that the gear member 50 moves in the vertical direction and makes a giving way action, and when the gear returns to the meshing position, the spring releases the elastic force to mesh and fix the gear member 50 with the turntable member.
[0095] like Figure 1-5 As shown, the present application also relates to an LED wall lamp, comprising the angle-adjustable structure as described above;
[0096] It also includes: a lamp body base 110 connected to the back side end surface of the lamp body shell 10, and a light-emitting mask 120 connected to the front side end surface of the lamp body shell 10;
[0097] Among them, the lamp body shell 10 is connected to the light-emitting mask 120 through a plurality of third connecting parts 130, the lamp body base 110 is connected to the lamp body shell 10 by hinge along one side of its short side, and the other short side of the lamp body base 110 is connected to the lamp body shell 10 through a fourth connecting part 140.
[0098] Specifically, the lamp body base 110 refers to the bottom seat of the lamp body, which can achieve good bottom fixing and supporting effects. The light mask 120 is an important component of the lamp, mainly used to protect the light source and adjust the distribution of light, improve the lighting effect and the aesthetics of the lamp.
[0099] The lamp body shell 10 and the light-emitting mask 120 are detachably connected by the third connecting member 130, which can achieve the effect of easy disassembly and assembly.
