[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0043] Reference Figure 1 and Figure 2 In the prior art, the test device uses a dimming component 10a (i.e., an integrating sphere component) to adjust the light parameters of the LED core particles and perform light collection operations. The integrating sphere component includes a dimming unit 200a, a light collecting unit 300a, and an integrating sphere 400a. The dimming unit 200a includes a horizontally arranged turntable and a plurality of filters. The dimming unit 200a can rotate around a first axis 210a to allow light to pass through different filters to achieve light parameter adjustment. The light collecting unit 300a can allow the adjusted light to pass through for subsequent testing operations. Among them, the first axis 210a of the dimming unit 200a is parallel to the second axis 320a of the light collecting unit 300a and is arranged at intervals. This arrangement causes the integrating sphere component to occupy too much space, which will increase the processing and testing costs.
[0044] In view of this, the first embodiment of the present invention proposes a dimming component 10, which can effectively reduce the space occupied by the dimming component 10. The dimming component 10 is used to adjust the parameters of the light. It should be noted that the dimming component 10 can be used to adjust the parameters of the LED chip. Figures 3 to 7 The dimming component 10 according to the embodiment of the present application is introduced. Specifically, the dimming component 10 includes a base 100, a dimming unit 200 and a light receiving unit 300.
[0045] Reference Figure 3 and Figure 4The substrate 100 is used to carry the dimming unit 200 and the light collecting unit 300. The specific structure of the substrate 100 can be determined according to actual conditions. Some embodiments of the present application are described by taking the plate-shaped substrate 100 as an example.
[0046] Reference Figures 3 to 6 The dimming unit 200 is used to adjust the parameters of the light. The dimming unit 200 is rotatably connected to the base 100. It is understood that the dimming unit 200 can be provided with a rotating shaft, and the base 100 can be provided with a mounting hole. The rotating shaft of the dimming unit 200 can pass through the mounting hole of the base 100 to achieve a rotatable connection. It should be noted that the dimming unit 200 can rotate around the first axis 210 relative to the base 100 to adjust the parameters of the light. Figure 4 With reference to the orientation in , the direction of the first axis 210 may be from the lower left side to the upper right side.
[0047] Reference Figure 3 and Figure 4 The light receiving part 300 is used to allow the light with adjusted parameters to pass through. The light receiving part 300 is connected to the substrate 100. Specifically, the light receiving part 300 can be directly connected to the substrate 100, or can be indirectly connected to the substrate 100. Some embodiments of the present application are described by taking the indirect connection of the light receiving part 300 and the substrate 100 as an example.
[0048] The specific configuration of the light receiving unit 300 is described below. The light receiving unit 300 includes a light receiving hole 310, that is, the light whose parameters have been adjusted can pass through the light receiving hole 310. The light receiving hole 310 has a second axis 320. Figure 4 The direction of the second axis 320 may be the up-down direction, with reference to the orientation in FIG. 2 . The first axis 210 of the light receiving unit 300 and the second axis 320 of the dimming unit 200 are arranged crosswise. Specifically, in some embodiments, the first axis 210 of the light receiving unit 300 may be arranged perpendicularly to the second axis 320 of the dimming unit 200. In other embodiments, the first axis 210 of the light receiving unit 300 may be at other non-perpendicular inclination angles to the second axis 320 of the dimming unit 200. Some embodiments of the present application are described by taking the non-perpendicular arrangement of the first axis 210 and the second axis 320 as an example.
[0049] In the technical solution of the utility model, the dimming component 10 includes a base 100, a dimming unit 200 and a light receiving unit 300. The dimming unit 200 is rotatably connected to the base 100, and the dimming unit 200 can rotate around a first axis 210 relative to the base 100 to adjust the parameters of the light. The light receiving unit 300 is connected to the base 100. The light receiving hole 310 of the light receiving unit 300 has a second axis 320, and the light receiving unit 300 is used to allow the light with adjusted parameters to pass through. Figure 1 and Figure 2, compared with the solution in the prior art that the axis of the dimming part 200a is parallel to the axis of the light receiving part 300a and arranged at intervals. Figures 3 to 5 In this solution, the first axis 210 of the dimming unit 200 and the second axis 320 of the light receiving unit 300 are arranged crosswise, so this solution can optimize the structural arrangement of the dimming component 10, effectively reduce the space occupied by the dimming component 10, and realize the miniaturized design of the dimming component 10. Furthermore, this solution can also make the needle seat layout of the probe station more compact, reduce the space occupied by the needle seat, reduce the weight of the needle seat, and increase the rigidity of the needle seat.
[0050] Reference Figures 3 to 7 , the specific configuration of the dimming unit 200 is introduced below. In some embodiments, the dimming unit 200 includes a carrier 220 and a plurality of filters 230. The carrier 220 is used to carry the filters 230. The filters 230 can perform filtering operations to adjust light parameters. The filters 230 are arranged on the carrier 220 at intervals around the first axis 210. It can be understood that the filters 230 can be evenly spaced or non-uniformly spaced. Some embodiments of the present application are described by taking the even spacing between the filters 230 as an example.
[0051] The dimming unit 200 is configured to have a dimming state. When the dimming unit 200 is in the dimming state, the arrangement direction of one of the filters 230 is perpendicular to the direction of the first axis 210. Figure 4 The orientation in is used as a reference, that is, the filter 230 is arranged horizontally and the first axis 210 is arranged vertically, so that light can pass through the filter 230 and enter the light receiving hole 310.
[0052] In this solution, the carrier 220 can rotate around the first axis 210, so as to switch different filters 230 to make them perpendicular to the second axis 320, that is, the light can pass through different filters 230 to achieve parameter adjustment of the light.
[0053] Reference Figure 4 and Figure 5, the specific arrangement of the light receiving part 300 is introduced below. In some embodiments, the light receiving part 300 includes a light receiving lens 330. The light receiving lens 330 includes a light receiving hole 310. The carrier 220 defines a accommodating cavity 221, and the accommodating cavity 221 can accommodate part of the light receiving lens 330. Specifically, the side of the accommodating cavity 221 facing the light receiving part 300 can be set as an open space, and the light receiving lens 330 can be detachably connected to the base 100, so that the light receiving lens 330 is partially accommodated in the accommodating cavity 221. It can be understood that the arrangement of the light receiving lens 330 should not interfere with the normal rotation of the dimming part 200. In this solution, the light receiving lens 330 is partially accommodated in the accommodating cavity 221, which can further reduce the space occupied by the dimming component 10, so that the dimming component 10 can be adapted to the center of the needle seat.
[0054] Reference Figures 4 to 7 , the specific arrangement of the filter 230 on the carrier 220 is introduced below. In some embodiments, a plurality of depressions 223 are provided on the outer peripheral wall 222 of the carrier 220 that faces away from the accommodating cavity 221. Each filter 230 is respectively accommodated in each depression 223. It can be understood that the thickness of the filter 230 can be less than the depth of the depression 223. The depressions 223 are arranged at intervals around the first axis 210. The shape of the depression 223 can be determined to adapt to the shape structure of the filter 230. The embodiment of the present application is described by taking the arrangement of a circular filter 230 and a circular carrier 220 as an example. It should be noted that a through hole 2232 can be provided in the middle of the depression 223, so that light can pass through the filter 230 and the through hole 2232 and enter the light receiving hole 310.
[0055] In this solution, the opening 2231 of the sink 223 faces the side away from the accommodating cavity 221, that is, when the filter 230 needs to be replaced or installed or removed, the filter 230 can be installed or removed directly from the outside of the carrier 220, and the overall operation is more convenient.
[0056] Reference Figure 4 , Figure 6 and Figure 7 , the following describes the fixing method between the filter 230 and the carrier 220. In some embodiments, the dimming unit 200 includes an elastic member 240, and the elastic member 240 is arranged around the peripheral wall 222. The elastic member 240 is located on the side of each filter 230 away from the accommodating cavity 221, so as to fix the filter 230 to the carrier 220. It should be noted that the dimming unit 200 can be provided with a single elastic member 240, or a plurality of elastic members 240. It can be understood that a slot can be provided on the carrier 220, and the elastic member 240 can be accommodated in the slot.
[0057] In this solution, the elastic member 240 is used to fix the filter 230 , which can reduce the wear on the filter 230 . Moreover, since the elastic member 240 surrounds the carrier 220 , the elastic member 240 can be used to fix multiple filters 230 at one time, thereby improving the fixing efficiency of the filters 230 .
[0058] Reference Figure 4 and Figure 6 , the specific structural arrangement of the carrier 220 is introduced below. In some embodiments, along the direction of the first axis 210, the peripheral wall 222 has a first end 2221 close to the substrate 100, and the peripheral wall 222 also includes a second end 2222 away from the substrate 100. From the first end 2221 to the second end 2222, the distance from the peripheral wall 222 to the first axis 210 gradually increases, that is, the outer contour of the carrier 220 can adopt a truncated cone structure. The carrier 220 adopts the above arrangement, on the one hand, so that the filter 230 arranged on the carrier 220 can be perpendicular to the second axis 320 of the light receiving part 300, and on the other hand, when the carrier 220 is turned upside down, the filter 230 can be directly placed on the sink 223 without falling off, that is, multiple filters 230 can be placed on each sink 223 and then fixed by the elastic member 240 to ensure the stability and efficiency of the installation.
[0059] Reference Figure 4 In some embodiments, the angle between the first axis 210 of the dimming unit 200 and the second axis 320 of the light receiving unit 300 is α. Among them, 30°≤α≤60°. Exemplarily, α can be 30°, 35°, 40°, 50°, 55° or 60°. In this solution, the first axis 210 and the second axis 320 adopt the above-mentioned angle, which can effectively reduce the vertical space occupancy and the horizontal space occupancy of the dimming component 10 on the one hand, and on the other hand, it can also make the light receiving lens 330 fully accommodated in the accommodating cavity 221 of the carrier 220, so that the overall structure of the adjustment component is more compact.
[0060] Reference Figure 4 and Figure 6 In some embodiments, the dimming component 10 further includes an integrating sphere 400 connected to the base 100. The integrating sphere 400 can evenly reflect incident light in all directions. The integrating sphere 400 includes a light entrance hole 410. The hole axis of the light entrance hole 410 coincides with the first axis 210. Figure 6 Taking the orientation in as reference, the hole axis of the light entrance hole 410 and the first axis 210 are both arranged vertically.
[0061] Reference Figure 6In some embodiments, the dimming component 10 further includes a stopper 500, which is connected to the base 100, and the stopper 500 partially surrounds the carrier 220 and is spaced from the carrier 220. By providing the stopper 500, the present solution can protect the plurality of filters 230 arranged on the periphery of the carrier 220, reduce the situation where foreign matter enters the filters 230, and extend the service life of the dimming component 10.
[0062] Reference Figure 5 In some embodiments, a groove 224 may be provided at the end of the carrier 220 away from the substrate 100. A plurality of grooves 224 may be provided. Each groove 224 may be arranged at intervals around the first axis 210. In this solution, a plurality of grooves 224 are provided on the carrier 220, so that it is convenient for relevant personnel to move the grooves 224 to drive the carrier 220 to rotate.
[0063] The second aspect of the utility model provides a testing device, which includes the dimming component 10 of the above-mentioned embodiment. It can be understood that the testing device can test the parameters such as the luminous flux, color temperature, and spectral distribution of the LED chip, so as to evaluate its performance and quality. In the testing device of this scheme, the first axis 210 of the dimming part 200 and the second axis 320 of the light receiving part 300 are arranged crosswise. Therefore, this scheme can optimize the structural layout of the dimming component 10, effectively reduce the space occupied by the dimming component 10, and realize the miniaturized design of the dimming component 10. Furthermore, this scheme can also make the needle seat layout of the probe station more compact, reduce the space occupied by the needle seat, reduce the weight of the needle seat, and increase the rigidity of the needle seat.
[0064] Reference Figures 3 to 7 , the specific working process of a test device of an embodiment is introduced below. The probe seat supplies power to the LED chip, and the LED chip emits light. The light enters the integrating sphere 400 through the light entrance hole 410 and is diffusely reflected. The carrier 220 is rotated so that the predetermined filter 230 on the carrier 220 is horizontally arranged at the light receiving hole 310. The light passes through the filter 230 to implement the filtering operation. The filtered and adjusted light enters the light receiving hole 310 and is detected by other test devices of the test device. Specifically, the test device can be provided with a light detector, which can convert the optical signal into an electrical signal to achieve measurement and analysis.
[0065] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
