Description

Technical Field

[0001] The utility model relates to a lamp, in particular to a knob dimming lamp. Background Art

[0002] At present, the common lamps with dial color adjustment on the market mainly use the common dial switches on the market for adjustment. For example, a PCB board is added under the light source lamp bead board, and the dial switch is placed on the PCB board. A rotating sleeve is provided on the surface of the outer shell, and the rotating sleeve is rotated to drive the dial switch to achieve the dial shift. Another solution is to set a dial piece on the surface of the outer shell, and drive the dial switch in the outer shell through the slidable dial piece to achieve the dial shift. The above two methods require the use of relatively expensive dial switches, and because a slidable rotating sleeve or dial piece is provided on the outer shell, the sealing of the lamp is poor, and water vapor and the like can easily enter the interior of the lamp, affecting the life of the lamp.

[0044] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0045] like Figure 1-Figure 4 As shown, the first embodiment of the utility model provides a knob dimming lamp, comprising a housing 100, a light emitting component 200 and a knob dimming component 300, wherein the light emitting component 200 is disposed in the housing 100;

[0046] The knob dimming component 300 includes a dimming knob 1, a substrate 2, a slider 3 and a conductive sheet 4. The dimming knob 1 is disposed on the housing 100 and can rotate relative to the housing 100.

[0047] The slider 3 is disposed on the substrate 2 and can slide relative to the substrate 2 along a predetermined track;

[0048] The substrate 2 is provided with a plurality of contacts 5, and the conductive sheet 4 is provided on the slider 3;

[0049] The contact 5 is electrically connected to the light emitting component 200;

[0050] The dimming knob 1 can drive the slider 3 to move by rotating itself and utilizing the force transmission generated by magnetic force or object contact, so that the conductive sheet 4 is connected to different contacts 5 .

[0051] This solution uses a dimming knob 1 to drive a slider 3 on a substrate 2 to slide along the surface of the substrate 2, so that the conductive sheet 4 provided on the slider 3 connects to different contacts 5, thereby achieving the adjustment of lighting parameters such as different color temperatures and brightness. This solution simplifies the existing dimming control structure and reduces production costs. The dimming knob 1 is used to adjust the lighting parameters, and the control is more sensitive and convenient; the axially rotating dimming knob 1 is designed relative to the sliding button, and its relative position with the shell is fixed during the adjustment process, and the sealing degree is high.

[0052] According to the first embodiment of the utility model, in order to limit the moving track of the slider 3 relative to the substrate 2, a slot 21 is provided on the substrate 2, and the slider 3 includes a sliding body 31 and a buckle 32, and the buckle 32 extends into the slot 21. The buckle 32 is used to prevent the slider 3 from being separated from the substrate 2, and when driven, the slider 3 moves along the slot 21.

[0053] In order to ensure that the conductive sheet 4 is reliably connected to the contact 5 and that the conductive sheet 4 stays at a position corresponding to a predetermined gear position, the slot wall of the slot 21 is provided with a plurality of limit slots 22, and the sliding body 31 is provided with a limit rod 33, one end of which is located in the limit slot 22. It should be noted that the limit rod 33 has a certain elasticity. When the slider 3 moves, the limit rod 33 moves accordingly. During this process, one end of the limit rod 33 is separated from the original limit slot and then enters the adjacent limit slot. The limit rod 33 can be a round rod, and the two side walls 221 of the limit slot 22 can also be set as an arc surface or an inclined surface. When the limit rod 33 begins to enter the limit slot 22, even if the driving force disappears, the slider 3 can reach the central position of the limit slot 22 along the arc surface or inclined surface side wall of the limit slot 22 under the elastic force of the limit rod 33. The position of each limit slot 22 is set so that when the limit rod 33 is located at the center, the slider 3 just moves the conductive sheet 4 to a position where two or more contacts 5 are reliably connected. With the above design, the operator does not need to rotate the knob accurately, but only needs to rotate it to an approximate position, and the dimming knob 1 and the slider 3 can stay at the predetermined gear position, which is convenient to operate and has a high-quality feel.

[0054] Preferably, in order to ensure that the limiting rod 33 has sufficient movable space and to maintain the elastic force required for normal operation of the limiting rod 33 during long-term use, the sliding body 31 is further provided with a limiting rod avoidance groove 311, which passes through the sliding body 31 vertically, and the limiting rod 33 is arranged in the limiting rod avoidance groove 311.

[0055] Combination Figure 8 As shown, preferably, the slot 21 is an arc-shaped slot, and the buckle 32 includes an offset block 321 and a claw 322. The side wall of the offset block 321 abuts against the side wall of the slot 21; the claw 322 is arranged at the bottom end of the offset block 321 and is clamped on the bottom surface of the substrate 2. The offset block 321 provides a position offset for the claw 322 when the buckle 32 is installed in the arc-shaped slot, and the claw 322 is used to hook the substrate 2 to prevent the slider 3 from being separated from the substrate 2. In addition, after the offset block 321 is installed, its side wall abuts against the side wall of the slot 21, providing a horizontal limit for the slider 3, so that when the slider 3 is moved by force, it will move along the slot 21. The movement of the slider 3 is realized by the cooperation of the buckle 32 and the slot 21, which ensures the smooth movement of the slider 3 on the one hand, and simplifies the structure and assembly steps on the other hand, saving costs.

[0056] The buckle 32 includes a first front buckle 32a and a first rear buckle 32b provided in the same slot 21, the offset block of the first front buckle 32a abuts against one side wall of the slot 21, and the offset block of the first rear buckle 32b abuts against the other side wall of the slot 21. The first front buckle 32a and the first rear buckle 32b cooperate to realize reliable positioning of the slider 3 in the single slot 21, which can reduce the volume of the slider 3 and the sliding friction of the slider 3, and the volume of the dimming knob 1 can also be reduced accordingly, which is conducive to promotion in lamps with small volume or compact internal space.

[0057] like Fig. 9 As shown, according to the second embodiment of the utility model, the difference from the first embodiment is that the slots 21 are in two groups, including a first slot 21a and a second slot 21b respectively extending along concentric arcs of different diameters; the buckle 32 includes a second front buckle 32c and a second rear buckle 32d arranged in different slots 21, the second front buckle 32c is arranged in the first slot 21a, and the second rear buckle 32d is arranged in the second slot 21b. In this embodiment, a first card slot 21a and a second card slot 21b are provided, each extending along a concentric arc of different diameters, and the contact 5 is provided between the first card slot 21a and the second card slot 21b, and the second front card buckle 32c cooperates with the first card slot 21a, and the second rear card buckle 32d cooperates with the second card slot 21b. The conductive sheet 4 is provided between the two buckles, and a downward pressure is applied to the conductive sheet 4 through the slider 3. The pulling force of the second front card buckle 32c and the second rear card buckle 32d is located on both sides of the downward pressure. The system is stably stressed and will not be excessively worn due to uneven local stress during long-term use, thereby improving the working reliability of the conductive sheet 4 and the contact 5 and extending the service life.

[0058] Combination Figure 4 and Figure 5As shown, the conductive sheet 4 includes a spring sheet fixing portion 41, a spring sheet deformation portion 42 and a spring sheet contact portion 43. The spring sheet fixing portion 41 has a U-shaped structure. The spring sheet deformation portion 42 connects the spring sheet fixing portion 41 and the spring sheet contact portion 43. The spring sheet contact portion 43 is symmetrically arranged on both sides of the spring sheet fixing portion 41. A spring sheet contact 44 is arranged at the bottom of the spring sheet contact portion 43. A retaining plate 45 is arranged on both sides of the spring sheet fixing portion 41. The retaining plate 45 is located in a retaining plate receiving hole 46. The upper end of the retaining plate 45 is connected to the spring sheet fixing portion 41. The sliding body 31 is provided with a conductive sheet mounting hole 312. The spring sheet fixing portion 41 extends into the conductive sheet mounting hole 312. The conductive sheet mounting hole 312 cooperates with the U-shaped spring sheet fixing portion 41 to fix the conductive sheet 4, leaving heat dissipation space for the top and bottom of the conductive sheet 4, and also reducing the material used for the slider 3. The conductive sheet 4 can be a spring sheet made of an alloy with copper as the main component to provide better conductive performance. The spring sheet deformation portion 42 is formed by gradually extending downward from the end of the spring sheet fixing portion 41 to the outside, providing a constant pressure for the spring sheet contact portion 43 to ensure that the spring sheet contact portion 43 is in reliable contact with the corresponding contact 5.

[0059] Specifically, a spring contact 44 is provided at the bottom of the spring contact portion 43. When the spring moves to a predetermined position, it can contact the two contacts 5, thereby conducting the circuits corresponding to the two contacts 5 and realizing the corresponding control function.

[0060] Preferably, the sliding body 31 is provided with retaining grooves 313 on both sides of the conductive sheet mounting hole 312, and the retaining plate 45 is disposed in the retaining grooves 313. The retaining grooves 313 are grooves that are recessed downward from the upper surface of the sliding body 31. When the conductive sheet 4 is installed in the conductive sheet mounting hole 312, the spring sheet fixing portion 41 extends from bottom to top into the conductive sheet mounting hole 312 until the retaining plate 45 contacts the hole wall of the conductive sheet mounting hole 312. The U-shaped spring sheet fixing portion 41 has a certain elastic deformation capacity, so the retaining plate 45 can be smoothly installed in the conductive sheet mounting hole 312 until it reaches the retaining grooves 313. The retaining plate 45 enters the retaining grooves 313 under the rebound action of the spring sheet fixing portion 41, and the conductive sheet 4 is fixed in the slider 3. With the above structure, the conductive sheet 4 is convenient to install, and after the conductive sheet 4 is fixed, its lower surface is not covered or blocked, so that efficient heat dissipation can be maintained.

[0061] During the use of the knob dimming lamp, the sliding smoothness of the slider 3 is particularly important, because it affects the rotation feel and the normal service life of the lamp. The sliding body 31 is provided with a first abutting surface 314 and a second abutting surface 315, both of which are used to abut against the upper surface of the substrate 2; the first abutting surface 314 is provided on the side of the sliding body 31 close to the contact 5, and the second abutting surface 315 is provided on the side of the sliding body 31 away from the contact 5, and the length of the first abutting surface 314 is greater than the length of the second abutting surface 315. It should be noted that the first abutting surface 314 is provided on the side of the sliding body 31 close to the contact 5, mainly to ensure the stability of the slider 3, prevent the slider 3 from tilting during the sliding process, so that the spring contact 44 can maintain stable contact with the contact 5 on the substrate 2, and the shorter second abutting surface 315 is provided to reduce the friction generated by the contact between the second abutting surface 315 and the substrate 2, so that the sliding of the slider 3 is smoother.

[0062] Combination Figure 7 As shown, preferably, the sliding body 31 is provided with a tooth surface 316, and the dimming knob 1 is provided with a gear 11, and the gear 11 is meshed with the tooth surface 316. The power of the dimming knob 1 is transmitted to the sliding body 31 through the meshing gear 11 and the tooth surface 316, which can ensure that the movement of the slider 3 is synchronized with the rotation of the dimming knob 1, and a corresponding pointer pattern can be set on the surface of the dimming knob 1, so that the operator can know the current gear position.

[0063] Combination Fig.10 As shown, according to the third embodiment of the utility model, the difference from other embodiments is that the tooth surface 316 is no longer provided on the sliding body 31, and the gear 11 is no longer provided on the dimming knob 1. Instead, the sliding body 31 and / or the dimming knob 1 are provided with a flexible friction layer 316, and the sliding body 31 and / or the dimming knob 1 abut against each other through the flexible friction layer 316. The flexible friction layer 316 can be made of materials such as silicone, so that it has a large friction force and a certain elasticity. The sliding body 31 and the dimming knob 1 abut against each other, and rely on the flexible friction layer 316 set at their connection to transmit power, and convert the rotation force of the dimming knob 1 into the power of the slider 3 moving along the slide groove. The flexible friction layer 316 is used to transmit the adjustment power, so that the operator has a soft hand feeling, especially when the limit rod 33 enters different limit grooves 22, the recoil force when the limit rod 33 slides into the center of the limit groove 22 can be buffered, so that the operator has a richer hand feeling when turning the dimming knob 1.

[0064] like Figure 7As shown, the housing 100 is provided with a knob cover 6, and the end of the knob cover 6 is provided with a first limiting ring 61; the side of the dimming knob 1 is provided with a second limiting ring 12 and a knob buckle 13, the second limiting ring 12 is arranged in cooperation with the front end face of the first limiting ring 61, and the knob buckle 13 is arranged in cooperation with the rear end face of the first limiting ring 61. The side of the dimming knob 1 is also provided with a sealing groove 14, and a sealing ring 15 is arranged in the sealing groove 14, and the sealing ring 15 abuts against the inner wall of the knob cover 6. The sealing ring 15 is used to ensure the sealing between the dimming knob 1 and the rotating cover, so that the lamp has a certain waterproof performance.

[0065] Preferably, the front end surface of the first limiting ring 61 is provided with a first conical surface 611, and the second limiting ring 12 is provided with a second conical surface 121 matching the first conical surface 611. The first conical surface 611 and the second conical surface 121 cooperate with each other to limit the dimming knob 1 on a predetermined rotation axis and have an automatic adjustment function.

[0066] Combination Figure 6 As shown, according to a specific embodiment of the utility model, the contact 5 includes a gear contact 51 and a common contact 52, and the gear contact 51 and the common contact 52 are arranged on the active track of the conductive sheet 4. When different gears are selected, the conductive sheet 4 connects different gear contacts 51 with the common contact 52.

[0067] More preferably, the gear contact 51 is arranged on both sides of the common contact 52, and the conductive sheet 4 has two spring contacts 44. During the movement of the conductive sheet 4, one spring contact 44 is kept in contact with the common contact 52, and the other spring contact 44 is kept in contact with a certain gear contact 51. The above arrangement can make the arrangement of the contacts 5 more compact and can also shorten the required length of the common contact 52.

[0068] Combination Figure 2As shown, according to a specific embodiment of the utility model, the knob dimming lamp also includes a lamp holder 400 and a lampshade 500, wherein the lamp holder 400 is arranged at the lower part of the housing 100, and the lampshade 500 is arranged at the upper part of the housing 100. The substrate 2 can be a plate formed integrally with the housing, or can be an independent plate of different materials, such as a PCB board or an aluminum substrate. In this embodiment, the substrate 2 is made of aluminum alloy, and the light-emitting component 200 is arranged on the substrate 2. Integrating the substrate 2 required in the knob dimming component 300 and the aluminum substrate 2 commonly used in lamps and lanterns, which has both heat dissipation and support functions, can greatly simplify the structure of the lamp and improve the reliability of the lamp. The aluminum substrate 2 is conductive. When the aluminum substrate 2 is used as the substrate 2, in order to ensure that the contact 5 and the conductive sheet 4 will not be short-circuited due to contact with the aluminum substrate 2, the corresponding part of the aluminum substrate 2 can be coated with an insulating material, and then the contact 5 can be arranged on the surface of the insulating material. The light emitting component 200 includes a light source and a driving circuit, the contact 5 is electrically connected to the driving circuit, and the driving circuit is electrically connected to the light source. The light source can be a single LED light source, or an LED light source array composed of a plurality of LED particles; the driving circuit can be a common LED driving circuit. As required, the light source can also be a conventional light source such as a fluorescent lamp, a halogen lamp, and a tungsten filament lamp. In this case, the driving circuit needs to be replaced with a driving circuit of the corresponding light source.

[0069] It should be noted that the knob dimming component 300 can be applied to different lamps, such as downlights, spotlights and energy-saving lamps, so the housing 100 can be made into different shapes such as cylindrical, square or trapezoidal as needed. This embodiment takes a PAR lamp as an example to describe the corresponding shell structure. The housing 100 has a conical working part 101, and the knob dimming component 300 is located in the conical working part 101. The substrate 2 is a circular flat plate.
