Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive lighting testing devices, specifically to a measuring stand for automotive roof light illuminance. Background Technology
[0002] In automotive interior design, dome lights, as a crucial lighting device, directly impact the comfort of the in-vehicle environment and the visual experience of the driver and passengers. However, current national standards lack clear regulations on the optical characteristics of in-vehicle dome lights, resulting in a lack of unified standards for testing their illuminance in practical applications. Traditional testing methods typically involve fixing the dome light to a stand to simulate the installation height. Specifically, a sheet of white paper marked with test points is laid on the ground, and a lux meter is used to measure each point to evaluate the dome light's illumination performance. However, this method may not adequately simulate the complex light reflection and refraction conditions in a real in-vehicle environment. Furthermore, some testing methods are even simpler, relying solely on subjective evaluation by observing the illuminance of the illuminated target area and the overall visual effect after the dome light is installed on the vehicle. While direct, this method lacks quantifiable measurement data, is easily influenced by the subjective factors of the evaluator, and makes it difficult to guarantee the objectivity and consistency of the test results.

[0027] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.
[0029] Example 1:
[0030] Because national standards do not specify the optical characteristics of vehicle interior dome lights, there is currently no unified method for illuminance testing. The basic approach is to install the dome light on the vehicle, turn it on directly, observe the approximate illuminance in the target area, and then make a subjective evaluation of the lighting effect. This lack of quantitative measurement data makes it susceptible to the influence of the evaluator's subjective factors, making it difficult to guarantee the objectivity and consistency of the test results.
[0031] like Figures 1 to 7 As shown, to solve the above problems, this embodiment provides a measuring stand for automotive dome light illuminance, including a frame 1. A dome light mounting platform 2 and a target plane 3 are mounted on the frame 1. A height adjustment mechanism 4 is provided between the dome light mounting platform 2 and the frame 1. A dome light fixing plate 5 is mounted on the dome light mounting platform 2. A first adjustment mechanism 6 is provided between the dome light fixing plate 5 and the dome light mounting platform 2. A base 7 is provided between the target plane 3 and the frame 1. An angle adjustment mechanism 8 is provided between the base 7 and the target plane 3. A second adjustment mechanism 9 is provided between the base 7 and the frame 1. The adjustment mechanism 6 and the second adjustment mechanism 9 are used, one for adjustment in the X-axis direction and the other for adjustment in the Y-axis direction. In this embodiment, the first adjustment mechanism 6 is used to adjust the dome lamp fixing plate 5 relative to the dome lamp mounting platform 2 in the Y-axis direction, and the second adjustment mechanism 9 is used to adjust the target base 7 relative to the frame 1 in the X-axis direction. In this way, the dome lamp mounting position can be adjusted, and the target flat plate can be adjusted in position and angle as needed. This can simulate the illumination scene of dome lamps of most car models and is applicable to the illuminance measurement of dome lamps of most car models, realizing process visualization, data standardization and measurement accuracy.
[0032] Secondly, test circles are set on the target plane disk 3. Specifically, multiple test circles of different sizes, such as 300mm and 500mm, are concentrically set on the target plane disk 3. Test points are set on the test circles, and then a lux meter can be used to measure each test point to evaluate the lighting performance of the ceiling light.
[0033] In this embodiment, the first adjustment mechanism 6 includes two first slide rails 60 spaced apart on the ceiling light mounting platform 2 and a first slider 61 disposed on the first slide rails 60. The ceiling light fixing plate 5 is disposed on the first slider 61. The first slide rails 60 are disposed along the Y-axis direction. The ceiling light fixing plate 5 is provided with a plurality of through holes 50. The ceiling light fixing plate 5 is used to fix ceiling light fixtures of different specifications through the through holes 50. The ceiling light fixtures can be specially customized for different ceiling lights. Generally, it is only necessary to provide threaded holes on the ceiling light fixtures and then connect the bolts through the through holes 50 to the threaded holes to fix the ceiling light. Preferably, the through holes 50 are evenly disposed on the ceiling light fixing plate 5.
[0034] In some embodiments, the ceiling light fixing plate 5 and the ceiling light mounting platform 2 are connected by a first adjusting handle 51 threadedly on one side and abutting against the end of the first adjusting handle 51 on the other side. By rotating the first adjusting handle 51, the ceiling light fixing plate 5 can be moved or fixed relative to the ceiling light mounting platform 2. In this embodiment, a fixing block is provided on one side of the ceiling light fixing plate 5, and the first adjusting handle 51 is threadedly connected to the fixing block. The end of the first adjusting handle 51 can abut against the upper surface of the ceiling light mounting platform 2.
[0035] In some embodiments, the ceiling light fixing plate 5 and the ceiling light mounting platform 2 are provided with a first scale 100 along the Y-axis on one side and a first indicator block 101 on the other side. In this embodiment, the ceiling light mounting platform 2 is provided with the first scale 100 along the Y-axis, and the ceiling light fixing plate 5 is provided with the first indicator block 101 on the other side of the fixing block. When the ceiling light fixing plate 5 moves along the Y-axis, the first indicator block 101 moves along the first scale 100.
[0036] In this embodiment, the second adjustment mechanism 9 includes a first adjustment component and a second adjustment component. A base 90 is provided between the base 7 and the frame 1. The first adjustment component is disposed between the base 7 and the base 90, and the second adjustment component is disposed between the base 90 and the frame 1. The first adjustment component includes two first slide rods 91 spaced apart on the frame 1 and a first slide block 92 disposed on the first slide rods 91. The base 90 is connected to the first slide block 92. The second adjustment component includes two second slide rods 93 spaced apart on the base 90 and a second slide block 94 disposed on the second slide rods 93. The base 7 is connected to the second slide block 94. Both the first slide rods 91 and the second slide rods 93 are arranged along the X-axis direction. By using the two adjustment components in the X-axis direction, the adjustable range of the target flat disk 3 in the X-axis direction is expanded.
[0037] Secondly, the base 90 and the frame 1 are connected by a first locking handle 95 threadedly on one side, and the other side abuts against the first locking handle 95. The base 7 and the base 90 are connected by a second locking handle 96 threadedly on one side, and the other side abuts against the second locking handle 96. The frame 1 and the base 90 are provided with a second scale 102 along the X-axis on one side, and a second indicator block 103 correspondingly on the other side. The base 7 and the base 90 are provided with a third scale 104 along the X-axis on one side, and a third indicator block 105 correspondingly on the other side. In this embodiment, the first locking handle 95 is disposed on the base 90, and the frame 1 is specially provided with a first locking rod that cooperates with it. The first locking rod is disposed along the X-axis direction. At the same time, the second indicator block 103 is disposed on the base 90, and the second scale 102 is disposed on the frame 1. The base 90 is provided with a fixing plate facing upward. The second locking handle 96 is disposed on the fixing plate. The base 7 is provided with a corresponding second locking rod that is disposed along the X-axis direction. At the same time, the third indicator block 105 is disposed on the fixing plate, and the third scale 104 is disposed on the base 7.
[0038] Furthermore, a fixing groove 10 is provided on the frame 1 along the Y-axis direction. The frame 1 is made of national standard aluminum profile and has a fixing groove 10 on it. Fixing seats 11 are provided at both ends of the second slide rod 93. The fixing seats 11 are connected to the fixing groove 10 by bolts, generally T-bolts. This allows the base 90 to be adjusted relative to the frame 1 along the Y-axis direction, further improving the adjustability of the measuring platform.
[0039] In this embodiment, the height adjustment mechanism 4 includes two second slide rails 40 spaced apart on the frame 1, a second slider 41 mounted on the second slide rails 40, a lead screw 42, and a sliding seat 43. The ceiling light mounting platform 2 is connected to the second slider 41. The second slide rails 40 are arranged along the height direction of the frame 1. The lead screw 42 is arranged along the height direction of the frame 1 and located between the two second slide rails 40. The sliding seat 43 is mounted on the lead screw 42 and connected to the ceiling light mounting platform 2. A second adjustment handle 44 is provided at the top of the lead screw 42. The ceiling light mounting platform 2 and the frame 1 have a fourth scale 45 arranged along the height direction of the frame 1 on one side and a corresponding fourth indicator block 46 arranged on the other side. Thus, the height of the ceiling light mounting platform 2 can be precisely adjusted by rotating the second adjustment handle 44. The height direction of the frame 1 is the Z-axis direction.
[0040] It is understandable that each linear adjustment mechanism is equipped with a scale to facilitate data recording and analysis, as well as to accurately simulate the illumination scenarios of each overhead light.
[0041] Preferably, the surface of the measuring platform is blackened, that is, the surfaces of all components such as the frame, the top light mounting platform 2, and the target plane disk 3 are blackened to prevent reflection from affecting the test results.
[0042] In this embodiment of the present disclosure, the angle adjustment mechanism 8 includes two spaced-apart mounting plates 80. The target flat plate 3 is rotatably mounted between the two mounting plates 80 via an angle adjuster 81. One of the mounting plates 80 is provided with an angle scale 82, and the target flat plate 3 is provided with an angle pointer 83 on the corresponding side. Thus, the target flat plate 3 has a vertical scale and an angle scale, and its position and angle can be freely adjusted to adapt to the lighting requirements of different types of ceiling lights.
