[0030] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar notations are used to denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as limiting the present application.

[0031] A lamp detection device 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0032] Referring to Figures 1-4 , the lamp detection device 100 according to the first embodiment of the first aspect of the present application comprises a detection table 1 and a grating piece 2, the detection table 1 has a lamp placing surface 11, and a lamp placing space is defined between the light-incident surface of the grating piece 2 and the lamp placing surface 11. For example, the grating piece 2 can be made of glass, and the grating piece 2 can also be made of plastic.

[0033] When identifying defects of the lamp to be detected 70, the lamp to be detected 70 can be first fixed on the lamp placing surface 11, then the grating piece 2 is placed on the side of the lamp to be detected 70 away from the lamp placing surface 11, and then the lamp to be detected 70 is turned on, and whether the lamp to be detected 70 has defects is determined by observing the light intensity of the light spot on the light-incident surface of the grating piece 2. Figure 4 As shown in

[0034] Since the grating piece 2 can filter light of a specific angle, that is, the light emitted by one of the adjacent two lamp beads in the lamp to be detected 70 towards the irradiation area of the other, can be filtered by the grating piece 2, that is, the grating piece 2 can reduce the light compensation between the adjacent two lamp beads.

[0035] When one of the plurality of lamp beads in the lamp to be detected 70 is not lit, the preset irradiation area of the lamp bead that is not lit on the grating piece 2 can be a first irradiation area (refer to the dark area in the middle of the white part in the picture taken by the lamp detection device 100 in Figure 4 ), the part of the light-incident surface of the grating piece 2 corresponding to the first irradiation area is a first light-incident point, and the preset irradiation area of the remaining lamp beads on the grating piece 2 is a second irradiation area (refer to the white part in the picture taken by the lamp detection device 100 in Figure 4 ), the part of the light-incident surface of the grating piece 2 corresponding to the second irradiation area is a second light-incident point.

[0036] Since the grating piece 2 filters out part of the compensation light at the irradiation area of the adjacent lamp beads, the light irradiated to the first irradiation area is less, the light irradiated from the first preset light emitting point is less, the light spot intensity formed by the grating piece 2 at the first preset light emitting point is weak, or even no light spot is formed by the grating piece 2 at the first preset light emitting point, so as to magnify the defects at the unlit lamp beads, form a relatively strong contrast between the light spot intensity at the first preset light emitting point and the light spot intensity at the second light emitting point, facilitate to identify the defects of the lamp, and the structure is simple and the identification is accurate.

[0037] With reference to Figures 1-3 According to some embodiments of the present application, the lamp placing surface 11 has a lamp placing area, the grating piece 2 has a first movement position and a second movement position spaced along a first direction (with reference to the e1 direction in the drawings) relative to the detection table 1, and in the first movement position, the lamp placing area is located in the projection of the grating piece 2 on the lamp placing surface 11, and the first direction is parallel to the lamp placing surface 11.

[0038] When identifying the defects of the to-be-tested lamp 70, the grating piece 2 can be first moved to the second movement position, then the to-be-tested lamp 70 is fixed on the lamp placing surface 11, and then the grating piece 2 is moved to the first movement position and placed on the side of the to-be-tested lamp 70 away from the lamp placing surface 11. After that, the lamp is lighted, and whether the to-be-tested lamp 70 has defects is judged by observing the brightness of the light spot on the light emitting surface of the grating piece 2.

[0039] By setting the first movement position and the second movement position spaced from each other for the grating piece 2, and in the first movement position, the lamp placing area is located in the projection of the grating piece 2 on the lamp placing surface 11, when placing the to-be-tested lamp 70, the grating piece 2 can be moved to the second movement position, and the grating piece 2 is placed to interfere with the installation of the to-be-tested lamp 70, facilitating the installation of the lamp.

[0040] Moreover, when detecting the to-be-tested lamp 70, since the lamp placing area is located in the projection of the grating piece 2 on the lamp placing surface 11, the grating piece 2 can be completely covered above the to-be-tested lamp 70, reducing the amount of light emitted by the lamp and irradiated to the light emitting surface of the grating piece 2 through diffuse reflection, reducing the light compensation of the first preset point by the diffuse reflection of the lamp, so that the grating piece 2 can reliably magnify the defects of the lamp, and improve the reliability of the lamp defect detection.

[0041] With reference to Figures 1-3According to some embodiments of the present application, the first motion position and the second motion position are spaced apart in a second direction (refer to the e2 direction in the drawings), the distance between the grating piece 2 and the lamp placement surface 11 at the first motion position is a detection distance, the distance between the grating piece 2 and the lamp placement surface 11 at the second motion position is an avoidance distance, the detection distance is less than the avoidance distance, and the second direction is perpendicular to the lamp placement surface 11.

[0042] At the first motion position, the grating piece 2 is arranged close to the to-be-detected lamp 70, which can make the distance between the grating piece 2 and the to-be-detected lamp 70 smaller, make the distance at which the light emitted by the lamp shoots shorter, make the amount of light emitted by the lamp that is irradiated to the first irradiation area through diffuse reflection smaller, make the intensity of the light spot at the first light exit point weaker, make the light irradiation intensity of the normal lamp beads irradiated to the second irradiation area stronger, make the intensity of the light spot at the second light exit point stronger, make the contrast between the intensity of the light spot at the first light exit point and the intensity of the light spot at the second light exit point more obvious, and make the grating piece 2 be able to more reliably amplify the defects of the lamp and improve the accuracy of lamp defect detection.

[0043] With reference to Figures 1-3 According to some optional embodiments of the present application, the lamp detection device 100 further comprises a support frame 3, the support frame 3 is arranged on the detection table 1, and the grating piece 2 is movably connected with the support frame 3. For example, the grating piece 2 can be movably arranged on the support frame 3 along the first direction; the grating piece 2 can also be rotatably arranged on the support frame 3; or the grating piece 2 can also be reversibly arranged on the support frame 3.

[0044] By arranging the support frame 3 connected with the grating piece 2, the support frame 3 can play a certain limiting role on the grating piece 2, facilitating the switching of the grating piece 2 between the first motion position and the second motion position, making the grating piece 2 be able to more reliably move to the first motion position, reducing the risk of collision between the grating piece 2 and the to-be-detected lamp 70, and improving the reliability of the lamp detection device 100.

[0045] With reference to Figures 1-3 In some optional embodiments of the present application, the support frame 3 comprises a grating support frame 31 and a plurality of support columns, each support column is connected between the grating support frame 31 and the detection table 1, and the plurality of support columns are arranged along the circumference of the support frame, and the support columns are located outside the lamp placement area, which can avoid interference between the support frame 3 and the installation of the to-be-detected lamp 70, and facilitate the installation and fixation of the to-be-detected lamp 70.

[0046] The grating support frame 31 is provided with a sliding groove 311 extending along the first direction, the grating piece 2 is arranged in the sliding groove 311, and the grating piece 2 is slidable along the extension direction of the sliding groove 311. The grating support frame 31 can support the grating piece 2 through the side wall of the sliding groove 311, so that the grating piece 2 is suspended above the to-be-detected lamp 70; and the grating support frame 31 can also limit the grating piece 2 through the side wall of the sliding groove 311, so that the grating piece 2 can be reliably switched between the first movement position and the second movement position, and the reliability of the lamp detection equipment 100 is improved.

[0047] With reference to Figures 1-3 In some optional embodiments of the present application, the plurality of support columns include a first support column 32 and a second support column 33, the first support column 32 and the second support column 33 are spaced apart in the first direction, and the height of the first support column 32 in the third direction (with reference to the e3 direction in the drawing) is less than or equal to the height of the second support column 33 in the third direction, that is, the grating support frame 31 is arranged obliquely. When the grating piece 2 is in the first movement position, the grating piece 2 is close to the first support column 32; when the grating piece 2 is in the second movement position, the grating piece 2 is close to the second support column 33.

[0048] When detecting the to-be-detected lamp 70, the grating piece 2 can be first slid towards the second support column 33, the grating piece 2 is switched to the second movement position, the distance between the grating piece 2 and the lamp placing surface 11 is enlarged, then the to-be-detected lamp 70 is placed in the lamp placing area through the gap between the grating piece 2 and the lamp placing surface 11, the to-be-detected lamp 70 is connected and fixed relative to the detection table 1, and then the grating piece 2 is slid towards the first support column 32, the grating piece 2 is switched to the first movement position, and the distance between the grating piece 2 and the to-be-detected lamp 70 is kept at a preset value.

[0049] In this way, the distance between the grating piece 2 and the lamp placing surface 11 can be increased by sliding the grating piece 2 towards the second movement position, the risk of interference between the grating piece 2 and the to-be-detected lamp 70 can be reduced, the occupied space of the grating piece 2 in the first direction can be reduced, the occupied space of the lamp detection equipment 100 in the first direction can be reduced, and the size of the lamp detection equipment 100 in the first direction is relatively compact.

[0050] Optionally, in some other embodiments of the present application, the height of the first support column 32 and the support degree of the second support column 33 can be kept equal, so that the occupied space of the grating piece 2 in the second direction can be reduced, the occupied space of the lamp detection equipment 100 in the second direction can be reduced, and the size of the lamp detection equipment 100 in the second direction is relatively compact.

[0051] With reference to Figures 1-3In some optional embodiments of the present application, the height difference between the first support column 32 and the second support column 33 is an avoidance height, the spacing between the first support column 32 and the second support column 33 in the first direction is an active spacing, and the ratio of the avoidance height to the active spacing is greater than or equal to 0.3 and less than or equal to 1.5. For example, the ratio of the avoidance height to the active spacing can be 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5.

[0052] The greater the ratio of the avoidance height to the active spacing, the greater the spacing between the grating piece 2 and the lamp placement surface 11 in the second motion position, and the more effectively the interference between the grating piece 2 and the to-be-tested lamp 70 can be reduced, and the more convenient the installation of the to-be-tested lamp 70. The smaller the ratio of the avoidance height to the active spacing, the smaller the occupied space of the grating piece 2 in the second direction, the smaller the occupied space of the lamp detection device 100 in the second direction can be set, and the smaller the size of the lamp detection device 100 in the second direction can be set.

[0053] By setting the ratio of the avoidance height to the active spacing to be greater than or equal to 0.3 and less than or equal to 1.5, the interference between the grating piece 2 and the to-be-tested lamp 70 can be effectively reduced while the occupied space of the grating piece 2 in the second direction is smaller, the installation of the to-be-tested lamp 70 is more convenient, and the size of the lamp detection device 100 in the second direction is more compact.

[0054] Referring to Figures 1-3 According to some embodiments of the present application, the diffusion angle of the grating piece 2 in the first direction is greater than or equal to 5° and less than or equal to 50°, and the first direction is parallel to the lamp placement surface 11. For example, the diffusion angle of the grating piece 2 in the first direction can be 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°.

[0055] The smaller the diffusion angle of the grating piece 2 in the first direction, the more effectively the grating piece 2 can reduce the light compensation between two adjacent lamp beads in the first direction, so that the light intensity at the first light emitting point among the two adjacent light emitting points in the first direction is weaker. The greater the diffusion angle of the grating piece 2 in the first direction, the more light rays irradiating the second irradiation area are emitted from the second light emitting point, and the greater the spot intensity at the second light emitting point.

[0056] The diffusion angle of the grating piece 2 in the first direction is greater than or equal to 5° and less than or equal to 50°, so that the spot intensity at the second light-emitting point is greater, the spot intensity at the first light-emitting point is smaller, and the comparison of the spot intensity at the first light-emitting point and the spot intensity at the second light-emitting point is obvious, thereby effectively and reliably amplifying the defects of the lamp, and improving the accuracy of lamp defect detection.

[0057] With reference to Figures 1-3 In some embodiments of the present application, the diffusion angle of the grating piece 2 in the third direction is greater than or equal to 5° and less than or equal to 50°, and the third direction is parallel to the lamp placement surface 11 and perpendicular to the first direction. For example, the diffusion angle of the grating piece 2 in the second direction can be 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°.

[0058] The smaller the diffusion angle of the grating piece 2 in the second direction, the more effectively the grating piece 2 can reduce the light compensation between the two adjacent lamp beads in the second direction, so that the light intensity at the first light-emitting point of the two adjacent light-emitting points in the second direction is weaker. The greater the diffusion angle of the grating piece 2 in the second direction, the more light rays illuminating the second illumination area are emitted from the second light-emitting point, and the greater the spot intensity at the second light-emitting point.

[0059] The diffusion angle of the grating piece 2 in the second direction is greater than or equal to 5° and less than or equal to 50°, so that the spot intensity at the second light-emitting point is greater, the spot intensity at the first light-emitting point is smaller, and the comparison of the spot intensity at the first light-emitting point and the spot intensity at the second light-emitting point is obvious, thereby effectively and reliably amplifying the defects of the lamp, and improving the accuracy of lamp defect detection.

[0060] With reference to Figures 1-3 According to some embodiments of the present application, the lamp detection device 100 further comprises a black box 5, the black box 5 defines a lamp detection space 51, the lamp detection space 51 is open to the first direction, the first direction is parallel to the lamp placement surface 11, and the detection table 1 and the grating piece 2 are arranged in the lamp detection space 51. For example, the second support column 33 can be arranged close to the opening of the lamp detection space 51.

[0061] By setting the black box 5 and placing the detection table 1 and the grating piece 2 in the lamp detection space 51, when the lamp is lit, the black box 5 can effectively absorb the light of the lamp, effectively reduce the amount of light emitted by the lamp that is irradiated to the light-emitting surface of the grating piece 2 through diffuse reflection, effectively reduce or even eliminate the light compensation of the first preset point by the lamp diffuse reflection, so that the grating piece 2 can reliably amplify the defects of the lamp, and improve the reliability of the lamp defect detection.

[0062] With reference to Figures 1-3 In some embodiments of the present application, the lamp detection device 100 further comprises a visual detection device 6 and an alarm device, the visual detection device 6 is arranged on one side of the light-emitting surface of the grating piece 2, and the visual detection device 6 is used to control the alarm device to alarm according to the brightness of the light-emitting surface at the preset point. For example, the alarm device can alarm in the form of sound, and the alarm device can also alarm in the form of light.

[0063] For example, the positions of the lamp beads, the diffusion angle of the grating piece 2, the distance between the lamp and the grating piece 2, and the distance between adjacent two lamp beads can be implanted in the visual detection device 6 first, and the visual detection device 6 analyzes all the light-emitting points (i.e. the preset points) expected to be formed by all the lamp beads on the light-emitting surface. The light-emitting points expected to be formed by each lamp bead on the light-emitting surface can also be drawn on the grating piece 2 with a pen.

[0064] When detecting the defects of the to-be-tested lamp 70, the light-emitting surface of the grating piece 2 can be photographed, and the light intensity of each preset point can be recognized and compared. If the light intensity of one of the preset points is lower than the average value of the light intensity of the remaining preset points, it is judged that the lamp bead corresponding to the preset point is damaged, and the to-be-tested lamp 70 is judged to be unqualified. The visual detection device 6 controls the alarm device to alarm. If the light intensity of all the preset points is substantially the same, i.e. the light intensity of each preset point is within the error range of the average value, it is judged that all the lamp beads are intact, and the to-be-tested lamp 70 is qualified.

[0065] In this way, the defects of the to-be-tested lamp 70 can be detected intelligently, the labor intensity of the workers can be reduced, the damage to the eyes of the workers caused by long-time direct vision of the light source can be reduced, the safety of the workers can be effectively ensured, and the overall performance of the lamp detection device 100 can be improved.

[0066] With reference to Figures 1-3 In some embodiments of the present application, a movable door is arranged at the opening of the lamp detection space 51, and the movable door has an open position and a closed position. In the closed position, the movable door seals the opening of the lamp detection space 51, and in the open position, the movable door opens the opening of the lamp detection space 51. For example, the movable door can be rotatably connected with the black box 5, and the movable door can also be slidably connected with the black box 5.

[0067] When detecting the to-be-tested lamp 70, the movable door can be switched to the open position first, then the to-be-tested lamp 70 is installed to the lamp placing area through the opening of the lamp detecting space 51, the grating piece 2 is switched to the first movement position, the to-be-tested lamp 70 is lighted, then the movable door is closed, and finally the to-be-tested lamp 70 is detected for defects by the sensing detecting device.

[0068] In this way, the external light can be effectively shielded from the compensation of the light-emitting surface of the grating piece 2, so that the grating piece 2 can reliably amplify the defects of the lamp, and the reliability of the lamp defect detection is improved.
