Description

Technical Field

[0001] The present invention relates to the technical field of dimming, and in particular to a dimming device for a multi-primary color LED lamp. Background Art

[0002] The photoelectric characteristics of multi-primary color LED lamps are formed by the mixed light of multiple chips of different colors. On the one hand, the current parameters of each primary color chip need to adopt different current parameters so that the color tolerance of the lamp meets the national standards; on the other hand, each component of the lamp will have tolerances, which will cause the light color parameters of each lamp to vary greatly; if a batch of lamps use the same current parameters, the light color parameters of each lamp will vary greatly, making the light color of the products inconsistent. Therefore, it is necessary to debug the current parameters of each primary color chip of the LED lamp.

[0003] Dimming of multi-primary color LED lamps requires that the current output control chip of each primary color is in good contact with the probe to ensure that the current parameters of each primary color are burned into the chip; however, there are only single-primary color LED lamp dimming equipment on the market. When the single-primary color LED lamp dimming equipment is used for current parameter debugging of multi-primary color chips, the position of the probe is generally adjusted manually so that the probe contacts the current output control chip of each primary color in turn, and the corresponding current parameters are burned in turn; because the probe does not always maintain contact with the current output control chip, the lamp needs to be constantly moved in and out of the integrating sphere machine to achieve the probe contacting the current output control chip of each primary color in turn, which leads to low debugging efficiency of multi-primary color LED lamps.

[0014] A further solution is that a rubber pad is provided on the outer wall of the inlet end of the integrating sphere machine.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) the present application first rotates the second limit block to fit with the upper surface of the lamp, and then drives the lifting block to move upward, so that the probe contacts the pad of the current output control chip of the lamp. Since the second limit block abuts against the upper surface of the lamp, the lamp will not be lifted up by the probe, which is conducive to full contact between the probe and the pad. Moreover, the probe is connected to the lifting block through the second spring. Even if individual probes are worn, the present application can achieve that each probe contacts the pad of each primary color current output control chip at the same time and maintains the state of each probe contacting the pad of each primary color current output control chip, so that the current parameters can be continuously burned into each primary color current output control chip through the probe, and the light source parameters of the lamp can be continuously tested through the integrating sphere, thereby greatly improving the test efficiency. (2) After the residual gear of the present application drives the rotating rod to rotate through the first transmission mechanism, the four corners of the rotating block will squeeze the spring sheet, causing the spring sheet to deform. When the four corners of the rotating block are separated from the spring sheet, the spring sheet will in turn cause the rotating block to rotate quickly into place, thereby realizing a 90° rotation of the second limit block. When the second limit block rotates into place, although the residual gear is not meshed with the first gear at this time, the spring sheet will prevent the rotating block from rotating, thereby keeping the state of the second limit block stable. (3) The present application uses the mutual cooperation of the protruding rod, the first horizontal groove, the inclined groove, the second horizontal groove, the lifting sleeve, the second limit block and the rotating rod, so that when the protruding rod cooperates with the first horizontal groove, the outer surface of the upper end of the lifting sleeve fits against the side of the lamp, and the bottom end of the second limit block fits against the upper surface of the lamp. When the protruding rod cooperates with the first horizontal groove, the lifting sleeve will not move up and down relative to the rotating rod under the action of external force; when the probe is placed on the top of the lamp, one end of the lamp will not be lifted up, which can ensure that each probe maintains good contact with the soldering pad on the lamp; and when the protruding rod cooperates with the second horizontal groove, the lifting sleeve and the second limit block are both located below one side of the lamp. Since there are no limits on the top of the lamp and on the side of the lamp away from the integrating sphere machine, it is more convenient to install the lamp on the carrier or remove it from the carrier, thereby facilitating the installation and removal of the lamp.

DETAILED DESCRIPTION

[0019] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Example 1 See also Figure 1-Figure 6 This embodiment provides a multi-primary color LED lamp dimming device, including a test machine 1 and an integrating sphere machine 2. The test machine 1 is provided with an operating room 3, and a slide seat 7 is slidably matched on the bottom wall of the operating room 3. A shading plate 5 is installed at the end of the slide seat 7 away from the integrating sphere machine 2. A rubber pad 201 is provided on the outer wall of the inlet end of the integrating sphere machine 2, and an integrating sphere is provided inside the integrating sphere machine 2. In the production process of the light source, the integrating sphere can quickly and accurately measure the key parameters of the light source such as brightness and chromaticity. A carrier 8 is installed on the slide seat 7, and a lamp 9 is placed on the carrier 8. A conveying mechanism 6 is provided at the bottom of the slide seat 7. The conveying mechanism 6 is used to send the slide seat 7 into the integrating sphere machine 2, and make the shading plate 5 fit with the rubber pad 201 at the inlet end of the integrating sphere machine 2. The shading plate 5 and the rubber pad 201 are closely fitted to achieve a shading effect, thereby preventing external light from entering the inside of the integrating sphere machine 2 through the inlet end.

[0023] In this example, see Figure 3 The bottom wall of the operating room 3 is provided with a guide rail 4 and a slide rail for slidingly cooperating with the lower surface of the shading plate 5 and the slide seat 7. The conveying mechanism 6 includes a first motor 601. A first receiving groove 605 for accommodating the first motor 601 is provided in the test machine 1 located below the operating room 3. The first receiving groove 605 is connected to the operating room 3 through a connecting groove 606. A screw rod 602 is fixedly connected to the output end of the first motor 601. The screw rod 602 passes through the first slider 603 and is threadedly connected thereto. The first slider 603 is connected to the bottom end of the shading plate 5 through a connecting block 604. When the first motor 601 drives the screw rod 602 to rotate, it will drive the first slider 603 to move along the central axis direction of the screw rod 602, and then drive the shading plate 5 and the slide seat 7 to move along the length direction of the guide rail 4, so as to deliver the lamp 9 on the slide seat 7 into the integrating sphere machine 2. It should be noted that the present application may also use other methods to drive the shading plate 5 and the slide 7 to move along the length direction of the guide rail 4, such as a cylinder and an electric telescopic rod. The present application does not make specific limitations and all are within the protection scope of the present application.

[0024] Preferably, a rubber pad 201 is also provided at the end of the connecting groove 606 . When the shading plate 5 fits with the rubber pad 201 , the connecting block 604 fits with the rubber pad 201 at the end of the connecting groove 606 , thereby preventing light from entering the integrating sphere machine 2 through the connecting groove 606 .

[0025] See also Figure 3 and Figure 4A second limit block 11, a probe 1006 and a lifting block 1005 are provided on the side of the lamp 9 close to the shading plate 5. The second limit block 11 is driven to rotate by a driving mechanism so that the second limit block 11 is in contact with the upper surface of the lamp 9 or the second limit block 11 and the lamp 9 are staggered with each other. The driving mechanism can be a motor that directly drives the second limit block 11 to rotate or the motor drives the second limit block 11 to rotate through a transmission mechanism; and the lifting block 1005 can move up and down under the action of the upper mechanism 10, and a plurality of grooves are provided on the lifting block 1005. The bottom wall of each groove is connected to the probe 1006 through a second spring 1007, and the top of the probe 1006 is used to contact the pads of the primary color current output control chip of the lamp 9.

[0026] In some embodiments, the present application first drives the second limit block 11 to fit with the upper surface of the lamp 9 through the driving mechanism, and then drives the lifting block 1005 to move upward through the lifting mechanism 10, so that the probe 1006 contacts the pad of the current output control chip of the lamp 9. Since the second limit block 11 is against the upper surface of the lamp 9, the lamp 9 will not be lifted up by the probe 1006, and one end of the lamp 9 will not be tilted, which is conducive to the full contact between the probe 1006 and the pad, and the probe 1006 is connected to the lifting block 1005 through the second spring 1007. Even if there are individual probes, In the event of wear of the needle 1006, etc., it is also possible to achieve that each probe 1006 is in contact with the pad of each primary color current output control chip at the same time, and there is no need to manually adjust the position of the probe 1006 so that the probe 1006 is in contact with the pad of each primary color current output control chip in turn; therefore, the present application can maintain the state in which the probe 1006 is in contact with the pad of each primary color current output control chip, so that the current parameters can be continuously burned into each primary color current output control chip through the probe 1006, and the light source parameters of the lamp 9 can be continuously tested through the integrating sphere, and the test efficiency is greatly improved.

[0027] It should be noted that the present application has both the probe 1006 in contact with the pads of each primary color current output control chip and the probe 1006 in contact with the contact of the power supply AC input terminal of the lamp 9, and the other end of the probe 1006 is connected to the mains or a terminal such as a computer and a tablet through a wire. The mains continuously supplies power to the lamp 9 through the probe 1006, and the terminal such as a computer and a tablet burns the program including the current parameters into each primary color current output control chip of the lamp 9 through the probe 1006.

[0028] In order to prevent the lamp 9 from being displaced during transportation, the carrier 8 of this embodiment is equipped with a first limit block 801 and a limit rod 802 that fit the lamp 9. The first limit block 801 is arranged on both sides of the width direction of the lamp 9, and the limit rod 802 is arranged on both sides of the length direction of the lamp 9. Figure 6When the lamp 9 is placed on the carrier 8, the first limit block 801 fits with both sides of the lamp 9 in the width direction, and the limit rod 802 fits with both sides of the lamp 9 in the length direction, thereby limiting the displacement of the lamp 9 relative to the carrier 8, which is also conducive to the probe 1006 and the pad on the lamp 9 to maintain good contact.

[0029] See also Figure 4 and Figure 5 The slide seat 7 is provided with a second receiving groove 701, and the driving mechanism includes a second motor 702 installed in the second receiving groove 701, and the second motor 702 has a forward and reverse rotation function. The output end of the second motor 702 is fixedly connected to a rotating shaft 703, and three residual gears 704 are installed at intervals on the outer surface of the rotating shaft 703, and the rotating shaft 703 is used to drive the three residual gears 704 to rotate simultaneously. One of the residual gears 704 drives the rotating rod 710 to rotate through the first transmission mechanism, and the other two residual gears 704 are used to drive the corresponding lifting block 1005 to move up and down. Specifically, the first transmission mechanism includes a first gear 705, a second gear 706, a first bevel gear 708 and a second bevel gear 709. The residual gear 704 is intermittently meshed with the first gear 705, the first gear 705 and the second gear 706 are meshed together, and the first bevel gear 708 is also installed on the gear shaft of the second gear 706. The second bevel gear 709 is installed on the outer surface of the rotating rod 710. Since the first bevel gear 708 and the second bevel gear 709 are meshed together, the residual gear 704 can drive the rotating rod 710 to rotate. Among them, the gear shafts of the first gear 705 and the second gear 706 are rotatably connected to the first support plate 707, and the first support plate 707 is installed on the side wall of the second accommodating groove 701; and the second transmission mechanism includes a rack 1001, and the rack 1001 is slidably set on the slide groove 1003 through a third slider 1004; the slide groove 1003 is opened on the side wall of the second accommodating groove 701, and a first spring 1002 is set at the bottom end of the rack 1001. The top end of the rack 1001 passes through the square groove 803 opened on the carrier 8 and then abuts against the lower surface of the lifting block 1005, and the lower surface of the lifting block 1005 is fixedly connected with a third spring 1009 and slidably matched with a second guide rod 1008, and the bottom ends of the third spring 1009 and the second guide rod 1008 are both installed on the bottom wall of the square groove 803, and the second guide rod 1008 plays a guiding role.

[0030] When one of the broken gears 704 is meshed with the first gear 705, the other two broken gears 704 will not mesh with the rack 1001. When the broken gear 704 meshes with the first gear 705 to rotate the second limit block 11 to the right position, the other two broken gears 704 will mesh with the rack 1001, and then drive the lifting block 1005 to drive the probe 1006 to move upward, thereby ensuring that the probe 1006 will not lift the lamp 9. When the probe 1006 moves upward to the right position, the second motor 702 no longer works, but the broken gear 704 remains meshed with the rack 1001 to prevent the probe 1006 from being separated from the pads of the primary color current output control chip of the lamp 9 under the reset action of each spring. When the light source parameter test of the lamp 9 is completed, the conveying mechanism 6 moves the lamp 9 out of the integrating sphere machine 2, and then controls the second motor 702 to rotate in the opposite direction, so that the probe 1006 is disengaged from the soldering pads of each primary color current output control chip of the lamp 9, and then the second limit block 11 is rotated to be staggered with the lamp 9. Since the second limit block 11 is no longer located above the lamp 9, it can be avoided that the second limit block 11 hinders the lamp 9 from being removed from the carrier 8.

[0031] Since the residual gear 704 corresponding to the rotating rod 710 is not meshed with the first gear 705 during the testing of the lamp 9, in order to prevent the rotating rod 710 from rotating during the testing of the lamp 9, which causes the second limit block 11 to no longer fit the upper surface of the lamp 9. In this embodiment, a rotating block 711 is installed in the middle of the rotating rod 710, and the cross section of the rotating block 711 is square. Both sides of the outer surface of the rotating block 711 are abutted with spring pieces 712, and the end of the spring piece 712 away from the rotating block 711 is installed in the second receiving groove 701 through a second supporting plate 713. When the remaining gear 704 drives the rotating rod 710 to rotate through the first transmission mechanism, the four corners of the rotating block 711 will squeeze the spring piece 712, causing the spring piece 712 to deform. When the four corners of the rotating block 711 are separated from the spring piece 712, the spring piece 712 will in turn cause the rotating block 711 to quickly rotate into place, thereby realizing a 90° rotation of the second limit block 11. When the second limit block 11 is rotated into place, although the remaining gear 704 is not engaged with the first gear 705 at this time, the spring piece 712 will prevent the rotating block 711 and the rotating rod 710 from rotating, thereby keeping the state of the second limit block 11 stable.

[0032] Example 2 See also Figure 7-10In this embodiment, the upper outer surface of the rotating rod 710 is slidably matched with a lifting sleeve 716, the second limit block 11 is installed on the top outer surface of the lifting sleeve 716, and the outer surface of the rotating rod 710 is provided with a convex strip 7101 that cooperates with the inner wall of the lifting sleeve 716, so that the rotating rod 710 can drive the lifting sleeve 716 to rotate, and the lifting sleeve 716 can slide up and down relative to the rotating rod 710, thereby driving the second limit block 11 to rotate and move up and down. A barrel 717 is rotatably connected to the sliding seat 7 located on one side of the rotating rod 710, and the barrel 717 cooperates with the rotating rod 710 through a gear transmission structure; the gear transmission structure includes a third gear 714 and a fourth gear 715 that are meshed with each other, the third gear 714 is installed on the outer surface of the rotating rod 710, and the fourth gear 715 is installed on the bottom end of the barrel 717, the bottom end of the central axis of the barrel 717 is rotatably connected to the sliding seat 7, and the top end of the central axis of the barrel 717 is rotatably connected to the third support plate 718, and the third support plate 718 is installed on the side of the sunshade 5. The third support plate 718 is conducive to a more stable rotation of the barrel 717.

[0033] See also Fig. 9 The barrel 717 is provided with at least a first horizontal groove 7171 and a second horizontal groove 7173, and the first horizontal groove 7171 is connected to the second horizontal groove 7173 through an inclined groove 7172. An annular groove 7161 is provided on the outer surface of the rotating rod 710, and a protruding rod 721 and a limiting mechanism that are matched with the first horizontal groove 7171, the second horizontal groove 7173, the inclined groove 7172 and the annular groove 7161 are provided between the barrel 717 and the rotating rod 710. The limiting mechanism includes a first guide rod 719 provided between the barrel 717 and the rotating rod 710, the top end of the first guide rod 719 is mounted on the third support plate 718, the first guide rod 719 is slidably matched with a second slider 720, and the protruding rod 721 is provided at both ends of the second slider 720.

[0034] It should be noted that the number of first guide rods 719 can be set to two, so that the second slider 720 can move up and down along the central axis of the first guide rod 719, but the second slider 720 cannot rotate relative to the first guide rod 719; the number of first guide rods 719 can also be set to one, in which case the first guide rod 719 cannot be a round tube, and the first guide rod 719 can be a square tube.

[0035] During the rotation of the rotating rod 710, the lifting sleeve 716 will also rotate accordingly. Since the rotating rod 710 simultaneously drives the third gear 714 to rotate, and since the third gear 714 is meshed and connected with the fourth gear 715, it will drive the barrel 717 to rotate simultaneously, so that the first horizontal groove 7171, the inclined groove 7172 and the second horizontal groove 7173 are matched with the protruding rod 721 in sequence. When the first horizontal groove 7171 is matched with the protruding rod 721, the rotating rod 710 only drives the lifting sleeve 716 and the second limit block 11 to rotate; when the inclined groove 7172 is matched with the protruding rod 721, the rotating rod 710 can not only drive the lifting sleeve 716 and the second limit block 11 to rotate, but also pull down the second limit block 11 and the lifting sleeve 716; when the second horizontal groove 7173 is matched with the protruding rod 721, the rotating rod 710 also only drives the lifting sleeve 716 and the second limit block 11 to rotate. It should be noted that when the second horizontal groove 7173, the inclined groove 7172 and the first horizontal groove 7171 cooperate with the protruding rod 721 in sequence, if the inclined groove 7172 cooperates with the protruding rod 721, the rotating rod 710 can not only drive the lifting sleeve 716 and the second limit block 11 to rotate, but also lift the second limit block 11 and the lifting sleeve 716. When the protruding rod 721 cooperates with the first horizontal groove 7171, the outer surface of the upper end of the lifting sleeve 716 fits against the side of the lamp 9, and the bottom end of the second limit block 11 fits against the upper surface of the lamp 9. Since the protruding rod 721 cooperates with the first horizontal groove 7171, under the action of external force, the lifting sleeve 716 will not move up and down relative to the rotating rod 710; therefore, when the probe 1006 is on top of the lamp 9, one end of the lamp 9 will not be lifted, which in turn is conducive to each probe 1006 maintaining good contact with the soldering pads on the lamp 9; when the protruding rod 721 cooperates with the second horizontal groove 7173, the lifting sleeve 716 and the second limit block 11 are located below one side of the lamp 9. Since there is no limit on the top of the lamp 9 and the side away from the integrating sphere machine 2, it is more convenient to install the lamp 9 on the carrier 8 or remove it from the carrier 8, thereby facilitating the installation and removal of the lamp 9.

[0036] Therefore, the carrier 8 of the present embodiment is provided with a first limit block 801 and a limit rod 802 which are fitted with the lamp 9. The first limit block 801 is arranged on both sides of the width direction of the lamp 9, and the limit rod 802 is only arranged on the side of the lamp 9 which is away from the rotating rod 710 in the length direction, thereby simplifying the limit rod 802 at one end of the carrier 8 close to the sunshade 5. Fig.10 In this embodiment, the number of the rotating rod 710 can be one or two. When the number of the rotating rod 710 is one, the rotating rod 710 is disposed at the middle of one end of the carrier 8 away from the integrating sphere machine 2 .

[0037] It should be noted that, in the present embodiment, the width of the second limit block 11 of the present application is smaller than the diameter of the lifting sleeve 716, and preferably smaller than the radius of the lifting sleeve 716; during the disassembly of the lamp 9, when the barrel 717 rotates until the protruding rod 721 cooperates with the end of the first horizontal groove 7171, although the second limit block 11 has not rotated 90° at this time, the second limit block 11 has been staggered with the lamp 9, and when the protruding rod 721 and the inclined groove 7172 cooperate with each other, the second limit block 11 moves downward and rotates at the same time until the second limit block 11 moves to the bottom of one side of the lamp 9. During this process, the lamp 9 will not hinder the downward movement of the second limit block 11.

[0038] It should be further explained that the rest of this embodiment is the same as the above-mentioned embodiment 1.
