Description

Technical Field

[0001] This utility model relates to the field of multi-color LED lighting testing technology, specifically a lighting testing device. Background Technology

[0002] In the production process of multi-color powder-free lighting fixtures, since these fixtures utilize powder-free multi-color LED beads, each bead integrating multiple primary color LED chips, light detection is crucial. When one primary color LED chip in a bead emits light abnormally, it affects the light quality of the fixture, thus impacting product quality. Visual inspection alone can damage employees' eyesight over extended periods, and given the large number of LED beads in a fixture, visual inspection is prone to missed or false positives. Therefore, we propose an improved light detection device. Utility Model Content

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figures 1-4 This utility model provides a lighting detection device, including a machine base 1. The machine base 1 has a first chamber 14, a second chamber 15, and a third chamber 16 arranged sequentially from bottom to top. The first chamber 14 and the second chamber 15 are separated by a partition 12; the second chamber 15 and the third chamber 16 are interconnected. A cabinet door 13 is provided on the front surface of the first chamber 14. After opening the cabinet door 13, an electrical parameter measuring instrument 4 and a main unit 3 can be placed in the first chamber 14. The input terminal of the electrical parameter measuring instrument 4 is connected to a 220V AC mains power supply, and the output terminal of the electrical parameter measuring instrument 4 is connected to the power supply line of a lamp 6 via a quick-connect clamp 7. The electrical parameter measuring instrument 4 is used to measure the voltage, current, and power parameters of the lamp 6 under test.

[0027] The quick-connect clamp 7 is installed on the inner wall of the second chamber 15. The quick-connect clamp 7 facilitates a quick and detachable connection between the power supply line of the tested lamp 6 and the output line of the electrical parameter measuring instrument 4. It typically employs a spring-loaded design; simply insert the wire into the hole of the clamp to complete the connection. In practical applications, the wire connection between the tested lamp 6 and the electrical parameter measuring instrument 4 can also be achieved using terminal blocks; furthermore, there are no specific limitations, depending on the application space.

[0028] A carrier 5 is installed in the second chamber 15, on which the lamp 6 is placed. The carrier 5 serves to fix and position the lamp 6. Specifically, the carrier 5 includes a base plate 501, a handle 503 is installed on the front surface of the base plate 501, and several first limiting plates 502 are spaced apart in the middle of the upper surface of the base plate 501. The first limiting plates 502 have limiting grooves that are adapted to the lower surface of the lamp 6. Second limiting plates 504 are installed on both sides of the upper surface of the base plate 501. The second limiting plates 504 are used to fit against the sides of the lamp 6. After the lamp 6 is placed on the first limiting plates 502, the first limiting plates 502 can restrict the lamp 6 from moving forward and backward. At the same time, the second limiting plates 504 on both sides of the lamp 6 are adapted to the width of the lamp 6, and the second limiting plates 504 can restrict the lamp 6 from moving left and right.

[0029] To facilitate the placement of the lamp 6 onto the carrier 5, a support structure 17 is provided between the carrier 5 and the partition 12. A slider 172 is provided on the lower surface of the support structure 17, and the slider 172 slides in engagement with a slide rail 171. The front end of the slide rail 171 has a protrusion to prevent the slider 172 from slipping out. The slide rail 171 is mounted on the partition 12. In addition, a roller is provided on the protrusion at the front end of the slide rail 171, and the roller rolls in engagement with the lower surface of the base plate 501 of the carrier 5. Since a handle 503 is installed on the front surface of the base plate 501, the carrier 5 can be easily pulled out by holding the handle 503. After the front end of the carrier 5 is pulled out of the second chamber 15, it is convenient to place the lamp 6 to be tested onto the carrier 5, and then the carrier 5 can be pushed back into the second chamber 15. The partition 12 is provided with a baffle 173 corresponding to the rear surface of the base plate 501 of the carrier 5. A magnet 174 is installed on the baffle 173, and an iron block 175 corresponding to the magnet 174 is provided on the base plate 501. Through the cooperation of the magnet 174 and the iron block 175, the position of the carrier 5 relative to the second chamber 15 can be prevented from changing during the detection process. The first limiting plate 502 and the second limiting plate 504 can also prevent the position of the lamp 6 relative to the carrier 5 from changing. Therefore, the position of the lamp 6 relative to the second chamber 15 will not change.

[0030] Please see Figure 2 and Figure 3 A light color sensor 10 and a vision camera 11 are installed on the top wall of the third chamber 16. Since the third chamber 16 is connected to the second chamber 15, the light color sensor 10 can collect the color temperature and luminous flux of the lamp 6. The vision camera 11 is used to collect the color digital image of the lamp 6 after it is lit and to calculate the color characteristic parameter values ​​of each lamp on the lamp 6. Since the position of the lamp 6 relative to the second chamber 15 does not change, the shooting angle and distance of the vision camera 11 relative to the lamp 6 remain unchanged. Therefore, the area corresponding to each lamp on the lamp 6 in the color digital image is fixed. The color characteristic parameter values ​​of each lamp on the lamp 6 can be calculated based on the color digital image. Specifically, the color feature parameter values ​​of each LED on lamp 6 can be calculated by using a color digital image. The corresponding area of ​​each LED on the color digital image can be cropped into a sub-image, and the sub-image can be converted to the HSV color space and separated into hue channel image, saturation channel image and luminance channel image. Then, the histograms corresponding to the hue channel image, saturation channel image and luminance channel image are calculated respectively. Based on the histograms, the color feature parameter values ​​of each LED on lamp 6 can be calculated. For details, please refer to the prior art Chinese Patent Publication No. CN 112200200B A method for detecting LED light color, which will not be repeated in this application.

[0031] The host 3 is connected to the vision camera 11 via a USB cable. The host 3 matches the calculated color feature parameter values ​​of each LED with a pre-stored color feature parameter value range database to determine whether each LED in the lamp 6 is emitting light normally.

[0032] Preferably, the front surface of the equipment 1 is provided with a control panel 8, which is used to set at least the upper and lower limits of the power of the lamp 6; the host 3 is connected to the control panel 8 and the electrical parameter comprehensive measuring instrument 4 via an RS232 serial port cable. The host 3 compares the power parameters monitored by the electrical parameter comprehensive measuring instrument 4 with the set upper and lower limits of the power, thereby determining whether the power of the lamp 6 under test is within the preset range.

[0033] Preferably, the host 3 is also connected to the display 9 and the light and color sensor 10 via an RS232 serial cable. The host 3 receives data from each sensor, compares and analyzes it, and can determine whether the product is good or bad; and displays it on the display 9 in real time for the inspector to observe.

[0034] Preferably, the front surface of the equipment 1 is provided with a glass window 2 corresponding to the third chamber 16, and the inspector can also directly observe the condition of the lamp 6 being tested through the glass window 2.

[0035] In summary, this utility model provides a light detection device that integrates structural components such as a light color sensor 10, a vision camera 11, a main unit 3, a control panel 8, a display 9, a quick-connect clamp 7, an electrical parameter comprehensive measuring instrument 4, a drawer-type carrier 5, and a glass window 2. The drawer-type carrier 5 facilitates the installation of the light fixture 6, and the quick-connect clamp 7 facilitates the connection of the power supply line of the light fixture 6 under test to the electrical parameter comprehensive measuring instrument 4, thereby enabling the electrical parameter comprehensive measuring instrument 4 to measure the current, voltage, and power parameters of the light fixture 6 under test. The upper and lower power limits can be set through the control panel 8 to facilitate the judgment of the light fixture under test. The power of lamp 6 is within the preset range; the photoelectric parameters of the lamp 6 under test are collected by the light color sensor 10 and the vision camera 11. The host 3 receives the data from each sensor and compares and analyzes it to determine whether the product is good or bad. The data is displayed in real time on the display 9 for the inspector to observe. The inspector can also observe the condition of the lamp 6 under test through the glass window 2. This solves the problem of detecting poor lighting in multi-color lamp products during the production process, improves production efficiency, reduces the harm of light to the human eye, avoids missed detection and false detection, and helps to improve product quality and light color consistency.
