Description

Technical Field

[0001] This application relates to the field of optical equipment testing technology, and in particular to a light strip testing device. Background Technology

[0002] With the continuous development of electronic products, LED light strips, due to their rich colors, low power consumption, and long lifespan, are widely used in various speaker products to achieve visual interactive functions such as breathing lights and rhythmic lighting effects. However, in actual production, it has been found that the color difference or brightness variation of individual LEDs in the overall device configuration is difficult to perceive with the naked eye. This is mainly because: the light-emitting area of ​​a single LED is small, lacking lateral contrast; and factors such as casing obstruction and ambient light interference in the overall device environment further mask individual differences. However, when multiple LEDs are combined into a light strip, the color difference or brightness inconsistency will create a significant contrast between the densely arranged LEDs, resulting in a decline in the overall visual effect of the lighting. Users can easily perceive defects such as color skipping or dark spots, seriously affecting the consistency of the product's appearance.

[0003] In related technologies, the inspection of LED light strips mostly relies on manual visual inspection or sampling. However, manual visual inspection is inefficient, cannot meet the needs of mass production, and is highly subjective. Different personnel and different lighting conditions result in inconsistent judgment standards and a high rate of missed detection. In particular, it lacks effective means of identifying slight color differences or brightness deviations. Utility Model Content

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present application are shown in the drawings, not the entire structure.

[0019] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0022] like Figures 1 to 3 As shown, an embodiment of this application provides a light strip detection device. The light strip 7 includes a strip body 71 and light bodies 72 disposed on the strip body 71. The light strip detection device includes a placement seat 1, an optical fiber fixing assembly 2, an optical fiber sensor 3, and a pulse assembly 4. The placement seat 1 is used to place the light strip 7. The optical fiber fixing assembly 2 includes a mounting base 21 and optical fiber members 22 disposed on the mounting base 21. The number of optical fiber members 22 is the same as the number of light bodies 72. The optical fiber members 22 are located above the light strip 7, and their positions correspond one-to-one with those of the light bodies 72. The optical fiber members 22 are used to transmit the light signals corresponding to the light bodies 72. The optical fiber sensor 3 is connected to the optical fiber members 22 and is used to receive the light signals from the optical fiber members 22 and output the actual optical chromaticity parameters corresponding to the optical fiber members 22. The pulse assembly 4 is used to output different pulses to the light strip 7 so that all the light bodies 72 are lit up with different colors.

[0023] With this setup, when the optical colorimetric parameters of the light strip 7 need to be detected, the light strip 7 can be placed on the placement seat 1, and the fiber optic component 22 can be mounted above the light strip 7 via the mounting seat 21. The positions and quantities of the fiber optic component 22 and the lamp body 72 are all set in a one-to-one correspondence, so that the light signal emitted by each lamp body 72 can be transmitted specifically by a corresponding fiber optic component 22. The pulse component 4 is connected to the light strip 7. The pulse component 4 can output different pulses to the light strip 7 so that all the lamps 72 are lit up with different colors. The light signal emitted by the lamps 72 is transmitted to the corresponding interface position of the fiber optic sensor 3 through the corresponding fiber optic component 22. The fiber optic sensor 3 can receive the light signal of each fiber optic component 22 and output the actual optical chromaticity parameters corresponding to each fiber optic component 22, that is, the actual optical chromaticity parameters corresponding to each lamp 72. This facilitates the quantification of optical chromaticity parameters such as color temperature, wavelength, chromaticity coordinates, and saturation of the lamps 72. It also facilitates the comparison of parameters between different lamps 72 on the light strip 7 or the comparison of the actual optical chromaticity parameters of the lamps 72 with the preset optical chromaticity parameters. This allows for rapid and accurate detection of the lamps 72 on the light strip 7, reducing missed detections.

[0024] Optionally, the pulse component 4 can sequentially output red, green, blue, and white color pulses to the light strip 7, so that all the lamps 72 on the light strip 7 are lit up sequentially in red, green, blue, and white. The red, green, and blue primary color pulses excite the corresponding chip bands of the light strip 7, and the actual optical colorimetric parameters such as wavelength, brightness, and color coordinates of each primary color can be measured. The white light pulse verifies the overall color temperature and uniformity after the three colors are superimposed, avoiding omissions of mixing deviations in color testing and facilitating the complete extraction of spectral features. The sequential lighting of the four colors, combined with parallel fiber optic acquisition, can determine which lamp 72 is out of tolerance in a certain primary color or mixing, locate color difference or brightness anomalies, and facilitate full inspection of all four colors with a single installation.

[0025] Optionally, the pulse component 4 can send different digital pulses to the light strip 7 with a fixed 24-bit width. The 24 bits refer to the data bit width of each pulse signal, that is, using a 24-bit binary number (3 bytes) to define the color of a single lamp body 72. Driven with a fixed 24-bit full-amplitude value, each lamp body 72 operates under the same current, which facilitates the elimination of driving differences and ensures that the measured parameters only reflect the differences in the photoelectric characteristics of the lamp body 72 itself, making it easy to directly compare with the preset specification threshold. For example, the pulse component 4 can sequentially send the following five digital pulses to the light strip 7: the first pulse is 1111111100000000000000000, all the lamps 72 on the light strip 7 are red; the second pulse is 000000001111111100000000, all the lamps 72 on the light strip 7 are green; the third pulse is 000000000000000011111111, all the lamps 72 on the light strip 7 are blue; the fourth pulse is 11111111111111111111111111, all the lamps 72 on the light strip 7 are white; and the fifth pulse is 0000000000000000000000000, all the lamps 72 on the light strip 7 are off.

[0026] Optionally, the placement base 1 may have a receiving groove for placing the light strip 7. The cross-sectional dimensions of the receiving groove may be the same as or similar to the circumferential dimensions of the light strip 7, facilitating a certain degree of positioning of the light strip 7. When testing the light strip 7, the mounting base 21 may be pressed onto the placement base 1. The placement base 1 can support the mounting base 21, reducing displacement of the fixing base, ensuring that the fiber optic component 22 and the lamp body 72 are aligned and at a preset distance, thus reducing testing errors. Furthermore, with the mounting base 21 abutting against the placement base 1, the light strip 7 can be located within the receiving space formed by the fastening of the mounting base 21 and the placement base 1, facilitating the reduction of the influence of external light on the testing of the light strip 7.

[0027] Optionally, each fiber optic component 22 may include one or at least two fiber filaments. One fiber filament provides a small luminous surface and strong directivity, reducing assembly errors while ensuring luminous flux. Having at least two fiber filaments facilitates multi-point sampling, covers a larger luminous surface of the lamp body 72, and allows for a redundant design. Even if one fiber filament is contaminated or broken, the signal remains uninterrupted, improving test reliability.

[0028] Optionally, the fiber optic sensor 3 may have multiple fiber optic tubes, the number of which is the same as the number of fiber optic components 22, and the fiber optic tubes and fiber optic components 22 are connected in a one-to-one correspondence. The length of the fiber optic component 22 corresponding to different lamp bodies 72 may be the same, and the distance between different lamp bodies 72 and their corresponding fiber optic tubes may also be the same.

[0029] like Figures 1 to 3As shown, in an optional embodiment, the fiber optic fixing assembly 2 further includes a light-shielding strip 23, which is fixedly mounted on the mounting base 21 and extends to the placement base 1. The light-shielding strip 23 is located on both sides or around the light strip 7 so that it can form a shield on both sides or around the fiber optic component 22, which is convenient for isolating ambient stray light and preventing external light from entering the fiber optic sensor 3 through the fiber optic component 22. This ensures that the measured optical colorimetric parameters are only emitted by the lamp body 72 itself, thereby improving the detection accuracy and consistency of optical colorimetric parameters such as colorimetric and brightness of the lamp body 72.

[0030] Optionally, the light-shielding strip 23 may be made of an elastic light-shielding material, such as rubber or silicone, so that the bottom of the light-shielding strip 23 can elastically abut against the placement seat 1 to reduce light leakage gaps.

[0031] In an optional embodiment, the pulse assembly 4 includes a pulse transmitter 41 and a test point connector 42 connected to each other. The pulse transmitter 41 is detachably connected to the light strip 7 via the test point connector 42. The connection method between the test point connector 42 and the light strip 7 can be, but is not limited to, plug-in or magnetic connection, as long as the pulse electrical signal transmission can be guaranteed. The detachable connection facilitates the replacement of different light strips 7, and the replacement is quick and convenient, which helps to improve the detection efficiency.

[0032] Optionally, the test point connector 42 can be a flexible cable or ribbon cable with a three-core interface including a ground wire, a positive power supply, and a single-wire digital signal input terminal. One end is plugged into the corresponding port of the pulse transmitter 41, and the other end is made into a detachable plug or spring clip that matches the power supply or signal pad of the LED strip 7.

[0033] like Figures 1 to 2 As shown, in an optional embodiment, the placement base 1 is provided with at least two positioning posts 11, and the strip body 71 is provided with at least two positioning holes. The at least two positioning holes are respectively located at both ends of the strip body 71. The positioning posts 11 can be inserted into the strip body 71 through the positioning holes. During testing, the light strip 7 is laid flat, and the positioning holes on the light strip 7 can be aligned with the positioning posts 11 for insertion. This facilitates the positioning of both ends of the light strip 7 and reduces warping. This also helps to ensure that the position of each light strip 7 in the fixture is unique and repeatable. After the mounting base 21 is installed on the placement base 1, the fiber optic component 22 can be set one-to-one with the position of the lamp body 72, reducing repeated manual adjustments and improving clamping efficiency and test consistency.

[0034] Optionally, two positioning posts 11 can be provided. One positioning post 11 can be located at one end of the light strip 7, and the other positioning post 11 can be located at the other end of the light strip 7. Alternatively, the positioning posts 11 can also be located at other positions on the placement base 1 corresponding to the positions between the two ends of the light strip 7. For example, a positioning hole can also be provided at the middle position of the light strip 7, and the positioning post 11 can also be inserted into the middle of the light strip 7 through the positioning hole, which facilitates multi-point positioning of the light strip 7 at different positions.

[0035] In one optional embodiment, the placement base 1 is provided with a magnetic suction part, which can magnetically connect with the light strip 7. The magnetic suction part can attract the light strip 7 downwards onto the placement base 1 for vertical pressing, preventing the light strip 7 from tilting or shifting during the pressing of the mounting base 21 or during testing. The magnetic suction part can cooperate with the positioning post 11 to form a double fixation of the light strip 7 by insertion and magnetic attraction, reducing the positional deviation of the light strip 7 and allowing for repeated clamping, improving the replacement cycle and testing consistency.

[0036] In one optional embodiment, the optical fiber components 22 and the lamp body 72 are arranged in groups corresponding to each other. The distance between the optical fiber components 22 and the lamp body 72 in different groups is equal. Each optical fiber component 22 and the corresponding lamp body 72 can form an independent optical coupler group, and different groups maintain the same end face spacing. This makes it easy to ensure that the proportion of light flux entering the corresponding optical fiber component 22 of each lamp body 72 is consistent, reducing the detection error of optical color parameters such as brightness or color due to coupling differences, ensuring that the test results of the entire light strip 7 can be compared laterally, and improving the accuracy and repeatability of the data.

[0037] like Figures 1 to 3 As shown, in an optional embodiment, the LED strip detection device further includes a lifting drive component 51 and a lifting adjustment component 52. The lifting drive component 51 has a slidably connected fixed part and a lifting part. One of the fixed part and the lifting part is fixedly mounted on the placement seat 1, and the other is fixedly mounted on the mounting seat 21. The lifting drive component 51 can drive the mounting seat 21 to move closer to or further away from the placement seat 1 in the vertical direction. That is, the vertical distance between the mounting seat 21 and the placement seat 1 can be adjusted by the relative sliding of the lifting part and the fixed part. The lifting adjustment component 52 is connected to the lifting drive component 51 and is used to adjust the start or stop of the lifting drive component 51 so that the lifting part and the fixed part can slide and maintain different distances.

[0038] Specifically, the initial position of the lifting part can be located away from the fixed part, so that the fiber optic fixing assembly 2 is away from the placement seat 1, thereby reserving sufficient space for the replacement operation of the light strip 7. After the light strip 7 is placed on the placement seat 1, the lifting adjustment component 52 can control the lifting drive component 51 to start, so that the lifting part moves closer to the fixed part, so that the mounting seat 21 moves closer to the placement seat 1. When the lifting part and the fixed part reach a preset distance, for example, when the mounting seat 21 contacts and abuts the placement seat 1, the lifting adjustment component 52 can control the lifting drive component 51 to stop, and the lifting part and the fixed part can maintain a preset distance, reducing the relative displacement of the mounting seat 21 and the placement seat 1. After the light strip 7 is inspected, the lifting adjustment component 52 can control the lifting drive component 51 to start, and the lifting part can slide up to the initial position, so that the light strip 7 can be taken out from the placement seat 1 and replaced, reducing the repeated fastening and installation operations between the mounting seat 21 and the placement seat 1. Moreover, the lifting drive component 51 can repeatedly move vertically, so that the fiber optic component 22 can be aligned with the corresponding lamp body 72, reducing inspection errors.

[0039] Optionally, the lifting drive component 51 can be a cylinder structure, the fixing part can be the cylinder base, the lifting part can be the cylinder piston rod, and the lifting adjustment component 52 can include a reversing valve. The reversing valve is connected to the air pipes in and out of the cylinder to facilitate air supply, exhaust, and airflow reversal. The reversing valve can be a manual reversing valve, which can be controlled by a pneumatic control handle. Pushing the handle forward causes the cylinder to press down the mounting seat 21, and pushing the handle backward causes the cylinder to lift the mounting seat 21, which is convenient for manual control by the user. A mounting column can be provided on the placement seat 1, and the fixing part of the cylinder structure can be fixedly installed on the mounting column. Alternatively, the lifting drive component 51 can also be a screw and nut structure. The fixing part can include a seat and a screw rotatably mounted on the seat. The lifting part can include a nut, which is sleeved on the screw and can move along the screw. The nut can be fixedly connected to the mounting seat 21, and the seat can be fixedly mounted on the placement seat 1. The lifting adjustment component 52 can be a motor capable of forward and reverse rotation, and the screw and nut structure has high distance adjustment accuracy.

[0040] like Figures 1 to 4 As shown, in an optional embodiment, the light strip detection device further includes a host computer 6 connected to the fiber optic sensor 3. The host computer 6 receives the actual optical chromaticity parameters corresponding to the fiber optic components 22 and outputs the comparison results of the actual optical chromaticity parameters of each fiber optic component 22 with preset optical chromaticity parameters. The host computer 6 can receive the actual optical chromaticity parameters corresponding to multiple light bodies 72 in parallel. The optical chromaticity parameter comparison of all light bodies 72 in the entire light strip 7 can be completed in one operation for red, green, blue, and white colors, resulting in high detection efficiency. The host computer 6 can preset a threshold value for each color's optical chromaticity parameter. If the actual optical chromaticity parameter of a certain light body 72 is less than or greater than the preset threshold value, the actual optical chromaticity parameter of the corresponding light body 72 is output and displayed as unqualified. If the actual optical chromaticity parameter of a certain light body 72 is equal to the preset threshold value, the actual optical chromaticity parameter of the corresponding light body 72 is output and displayed as qualified. This numerical differentiation of slight color differences or brightness deviations reduces missed detections.

[0041] Optionally, if the lamp body 72 is defective, the host computer 6 can output the corresponding item of the actual optical chromaticity parameter as defective. For example, the light strip 7 may include 16 lamp bodies 72, and the host computer 6 can output that the red light of the second lamp body 72 is defective, which facilitates user maintenance of the light strip 7. The host computer 6 can communicate with the fiber optic sensor 3 through a universal serial bus interface. The host computer 6 can obtain the actual optical chromaticity parameter values ​​analyzed by each fiber optic component 22 by calling the application programming interface function of the fiber optic sensor 3.

[0042] like Figures 3 to 4As shown, in an optional embodiment, the host computer 6 has a display for displaying the comparison results of the actual optical chromaticity parameters of each fiber component 22 with the preset optical chromaticity parameters, so that users can intuitively read and observe the actual optical chromaticity parameters of each lamp body 72 under different colors.

[0043] Optionally, the display directly presents a matrix interface comparing the actual optical chromaticity parameters with preset optical chromaticity parameters for red, green, blue, and white. The vertical axis of the display matrix interface represents the lamp numbers from the first to the second end of the light strip, such as 0-19. The horizontal axis can include three cells for red, green, and blue, displaying the corresponding actual optical chromaticity parameters. The horizontal axis can also include cells for the chromaticity, saturation, luminance, wavelength, color temperature, and CIE1931X and CIE1931Y parameters for each lamp when the light strip receives a white pulse. CIE1931X and CIE1931Y are the X and Y coordinates in the CIE1931 chromaticity diagram, used to accurately describe colors perceived by the human eye. CIE1931X represents the relative proportion of red in a color, and CIE1931Y represents the relative proportion of green. Both are dimensionless values, ranging from 0 to 1, and can be combined with luminance values ​​to define a color. If the actual optical chromaticity parameter corresponding to a certain lamp body 72 is equal to the preset optical chromaticity parameter threshold, it is qualified and not highlighted. If the actual optical chromaticity parameter corresponding to a certain lamp body 72 is less than or greater than the preset optical chromaticity parameter threshold, it is unqualified and the specific value is highlighted. Users can locate which lamp body 72 and which color exceeds the standard at a glance, without the need to look up tables or memorize manually, greatly improving the speed and accuracy of judgment.

[0044] In one optional embodiment, a relay is connected in series in the control circuit of the pulse component 4. The relay is connected to the button, and the button controls the output pulse switching of the pulse component 4 through the relay. A relay can be connected in series on the pulse signal output line of the pulse component 4, with the relay coil terminal connected in series with the button. Each time the button is pressed, the relay is energized, and its contacts switch instantaneously, triggering the pulse to output the next color control code in the sequence of "red → green → blue → white". This reduces the intervention of the host computer 6, and color cycling can be performed solely through the mechanical button. The structure is simple, the cost is low, and the operation is intuitive. At the same time, the relay isolates the button contacts from the high-speed digital signal, avoiding jitter interference and ensuring the integrity of the pulse waveform.

[0045] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the scope of protection of this application. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
