[0011] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0012] It should be noted that the terms "having," "including," and "comprising" described in the present invention have open-ended meanings. That is, when a module is described as "having," "including," or "comprising" a first element, a second element, and / or a third element, it means that the module includes other elements in addition to the first element, the second element, and / or the third element. Furthermore, the terms used in the embodiments of the present invention are intended solely for the purpose of describing specific embodiments and are not intended to limit the present invention. It should be noted that the directional terms "upper," "lower," "left," and "right" described in the embodiments of the present invention are described from the perspectives shown in the accompanying drawings and should not be construed as limiting the embodiments of the present invention. Furthermore, in this context, it should be understood that when an element is referred to as being formed "on" or "under" another element, it can be formed not only directly "on" or "under" the other element, but also indirectly "on" or "under" the other element through an intermediate element. The terms "first," "second," and the like are used for descriptive purposes only and do not indicate any order, quantity, or importance, but are simply used to distinguish different components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific contexts.

[0013] Based on the shortcomings of the prior art mentioned in the background, embodiments of the present invention provide an integrated illumination lamp stand suitable for use in testing systems, including but not limited to this composite heat-resistant illumination testing system, for performing temperature and / or light testing on objects under test. The objects under test include, but are not limited to, vehicle parts. In some specific applications, the vehicle parts may be headlights. The integrated illumination lamp stand's function in the testing system is to provide a lighting environment for the object under test.

[0014] Figure 1 This is a schematic diagram of the structure of an integrated lighting fixture provided by the embodiment of the present invention, which can be referred to Figure 1The integrated illumination lamp holder includes: a base turntable 10, a bracket body 20 and a lamp holder assembly 30; one side surface of the base turntable 10 includes a rotating shaft 101, the axial direction of the rotating shaft 101 is perpendicular to the plane where the base turntable 10 is located, the bracket body 20 is fixed to the base turntable 10 by the rotating shaft 101, and the rotating shaft 101 drives the bracket body 20 to rotate; the lamp holder assembly 30 is fixed to the side of the bracket body 20 away from the base turntable 10, and the lamp holder assembly 30 includes a first illumination assembly 301 and a second illumination assembly 302, and the orthographic projections of the first illumination assembly 301 and the second illumination assembly 302 on the plane where the base turntable 10 is located are respectively located on opposite sides of the orthographic projection of the bracket body 20 on the plane where the base turntable 10 is located; wherein, the central wavelength of the light emitted by the first illumination assembly 301 is different from the central wavelength of the light emitted by the second illumination assembly 302.

[0015] like Figure 1 As shown, the height direction of the integrated illumination lamp stand can be defined as the vertical direction Z. The base turntable 10 is positioned close to the ground, and the bracket body 20 and the lamp stand assembly 30 are positioned above the base turntable 10. The bracket body 20 is connected to the base turntable 10 via a rotating shaft 101 mounted on the upper surface of the base turntable 10, allowing the bracket body 20 to rotate relative to the base turntable 10. In other words, the bracket body 20 can rotate axially about the rotating shaft 101. The lamp stand assembly 30 is fixed to the bracket body 20. Rotation of the bracket body 20 can drive the lamp stand assembly 30 to rotate 180° or 360° axially about the rotating shaft 101.

[0016] The rotating shaft 101 can be located at the center (or center of gravity) of the base turntable 10, so that the force on the base turntable 10 is relatively balanced. Along the vertical direction Z, the center of gravity of the bracket body 20 can coincide with the center of gravity of the base turntable 10, improving the stability of the integrated lighting stand.

[0017] It is worth mentioning that in the embodiment of the present invention, the lamp stand assembly 30 includes a first lighting assembly 301 and a second lighting assembly 302, and the orthographic projections of the first lighting assembly 301 and the second lighting assembly 302 on the plane where the base turntable 10 is located are located on both sides of the orthographic projection of the bracket body 20 on the plane where the base turntable 10 is located. The first lighting assembly 301 and the second lighting assembly 302 are arranged along a first direction X. In the initial state, the first direction X is parallel to the plane where the base turntable 10 is located, and the first direction X can be regarded as a horizontal direction. The initial state may refer to the position state of the first lighting assembly 301 and the second lighting assembly 302 after they are reset, when the integrated lighting stand has not performed the lighting test work. Figure 1 In the initial state, the first lighting assembly 301 and the second lighting assembly 302 are located on both sides of the bracket body 20 along the first direction X.

[0018] The wavelength range of the light source used in the first illumination component 301 differs from the wavelength range of the light source used in the second illumination component 302. For example, the light source in the first illumination component 301 has a first wavelength range, and the light source in the second illumination component 302 has a second wavelength range, and the first wavelength range and the second wavelength range at most partially overlap. For example, the first wavelength range may cover at least a portion of invisible light, and the second wavelength range may cover at least a portion of visible light, so that the first illumination component 301 and the second illumination component 302 can simulate a sunlight illumination environment.

[0019] In this utility model, illumination components of different wavelengths can be integrated into a single integrated illumination lamp holder. When switching light sources, the holder body 20 can be controlled to rotate, and the target illumination component (referring to one of the first illumination component 301 and the second illumination component 302) can be rotated toward the object under test. This allows the use of a single integrated illumination lamp holder to perform light aging tests on the object under test at different wavelengths. This eliminates the need for testers to manually change light sources, reducing their workload and improving testing efficiency.

[0020] The present invention does not limit the specific light sources used in the first and second illumination components 301 and 302. Those skilled in the art may configure these light sources based on actual needs. For example, the first illumination component 301 may include an infrared lamp, and the second illumination component 302 may include a halogen lamp, but the present invention is not limited thereto.

[0021] In addition, the embodiments of the present invention do not limit the specific structure of the bracket body 20 and the lamp holder assembly 30. Those skilled in the art can set it according to actual needs. Any structure that can realize the functions of the above-mentioned bracket body 20 and the lamp holder assembly 30 is within the scope of the technical solution protected by the embodiments of the present invention.

[0022] like Figure 1As shown, the integrated illumination lamp holder provided by the embodiment of the present invention includes: a base turntable 10, a bracket main body 20 and a lamp holder assembly 30; one side surface of the base turntable 10 includes a rotating shaft 101, the axial direction of the rotating shaft 101 is perpendicular to the plane where the base turntable 10 is located, the bracket main body 20 is fixed to the base turntable 10 by the rotating shaft 101, and the rotating shaft 101 drives the bracket main body 20 to rotate; the lamp holder assembly 30, the lamp holder assembly 30 is fixed to the side of the bracket main body 20 away from the base turntable 10, the lamp holder assembly 30 includes a first illumination assembly 301 and a second illumination assembly 302, the orthographic projections of the first illumination assembly 301 and the second illumination assembly 302 on the plane where the base turntable 10 is located are respectively located on opposite sides of the orthographic projection of the bracket main body 20 on the plane where the base turntable 10 is located; wherein, the central wavelength of the light emitted by the first illumination assembly 301 is different from the central wavelength of the light emitted by the second illumination assembly 302. This allows different wavelength illumination components to be integrated into a single integrated illumination fixture, enabling light aging testing of items under test at different wavelengths. This eliminates the need for testers to manually change light sources, reducing their workload and improving testing efficiency.

[0023] Optional, you can continue to refer to Figure 1 In a possible embodiment, the bracket body 20 may include a support frame 201 and a lifting structure 202, the support frame 201 is fixed to the rotating shaft 101, and the lifting structure 202 is respectively fixed to the support frame 201 and the lamp holder assembly 30; the lifting structure 202 drives the lamp holder assembly 30 to move up and down along the height direction of the support frame 201.

[0024] like Figure 1 As shown, the support frame 201 is the main framework of the bracket body 20. The support frame 201 can be composed of multiple support columns 2011 extending in the vertical direction Z and support beams 2012 extending in the horizontal direction, forming a cubic hollow frame structure. The first direction X can be parallel to some of the support beams 2012. The bottom of the support frame 201 is fixed to the rotating shaft 101. The lifting structure 202 can be fixed to the support frame 201. The lifting structure 202 includes a lifting member connected to the lamp holder assembly 30. The lifting member in the lifting structure 202 can move up and down in the vertical direction Z, thereby driving the lamp holder assembly 30 to move up and down in the vertical direction Z.

[0025] By controlling the up and down movement of the lamp holder assembly 30, the height of the first lighting assembly 301 and the second lighting assembly 302 can be adjusted, thereby adjusting the lighting height of the light source, that is, adjusting the distance between the light source and the object to be measured, and adjusting the lighting direction and intensity to improve the lighting simulation effect.

[0026] Optional, Figure 1In the integrated lighting stand shown, the support frame 201 includes a first bracket 2013 and a second bracket 2014, wherein the first bracket 2013 is located between the second bracket 2014 and the base turntable 10. The first bracket 2013 and the second bracket 2014 can both be a cubic hollow frame formed by connecting support columns 2011 and support beams 2012. Figure 1 In the example shown, the first bracket 2013 and the second bracket 2014 each include four support columns 2011 extending along the vertical direction Z and a plurality of support beams 2012, but the present invention is not limited thereto. The width of the first bracket 2013 in the first direction X may be greater than the width of the second bracket 2014 in the first direction X. Along the first direction X, the two support columns 2011 on one side of the first bracket 2013 and the second bracket 2014 may be integrally provided, while the two support columns 2011 on the other side may be staggered and separately provided.

[0027] The bottom connecting beam 20131 of the first bracket 2013 can be fixed to the rotating shaft 101 , the second bracket 2014 is fixed to the top of the second bracket 2014 , and the lifting structure 202 is entirely located within the frame of the second bracket 2014 .

[0028] The specific configuration of the lifting structure 202 is not limited, and any mechanical structure that can be lifted and lowered in the vertical direction Z is within the scope of the technical solution protected by the embodiment of the present utility model.

[0029] For example, continue to refer to Figure 1 In some embodiments, the lifting structure 202 includes a lifting screw assembly and a lifting motor 2021; the lifting screw assembly is fixed to the support frame 201, the extension direction of the lifting screw assembly is parallel to the height direction of the support frame 201, the lamp holder assembly 30 is mounted on the lifting screw assembly, and the lifting motor 2021 is connected to the lifting screw; the lifting motor 2021 controls the lamp holder assembly 30 to move up and down along the height direction of the support frame 201 through the lifting screw assembly.

[0030] like Figure 1 As shown, a first connecting beam 20121 can be disposed between the top support beams 2012 of the first bracket 2013. The first connecting beam 20121 connects the two opposing support beams 2012 disposed at the top of the first bracket 2013. A second connecting beam 20122 can be disposed between the top support beams 2012 of the second bracket 2014. The second connecting beam 20122 connects the two opposing support beams 2012 disposed at the top of the second bracket 2014. The lifting screw assembly extends in a vertical direction Z (i.e., the height direction of the support frame 201), with its ends secured to the first connecting beam 20121 and the second connecting beam 20122, respectively.

[0031] The lifting motor 2021 can be fixed to the first connecting beam 20121 and is in transmission connection with the lifting screw assembly. The lifting screw assembly can include a screw body 2022 and a lifting nut 2023. The lifting nut 2023 is disposed around the outer periphery of the screw body 2022 and is threadedly connected to the screw body 2022. The lifting nut 2023 can be the lifting member described above. The lifting nut 2023 is fixed to the lamp holder assembly 30. The lifting motor 2021 can drive the screw body 2022 to rotate. The rotation of the screw body 2022 drives the lifting nut 2023 to move up and down in the vertical direction Z, thereby achieving up and down movement of the lamp holder assembly 30.

[0032] The present utility model exemplifies that the lifting screw assembly and the lifting motor 2021 use the motor screw nut assembly in the prior art. In actual application, the lifting structure 202 is not limited to this structure, and any actuator with a linear drive function can also be selected, such as a motor gear rack assembly, a linear motor, an electric push rod, and a hydraulic rod. Examples will not be given one by one here.

[0033] Further, you can continue to refer to Figure 1 The support frame 201 includes multiple support columns 2011 and a support beam 2012 connected between two adjacent support columns 2011; the lifting structure 202 also includes a guide rod 2024 and a linear bearing 2025. The guide rod 2024 extends in the same direction as the support column 2011 and is fixed to the support column 2011. The linear bearing 2025 is slidably sleeved on the outside of the guide rod 2024. The lamp holder assembly 30 is also fixed to the linear bearing 2025. The linear bearing 2025 cooperates with the lifting screw to drive the lamp holder assembly 30 to move.

[0034] The arrangement of the support columns 2011 and the support beams 2012 has been described above and will not be repeated here. In this embodiment, the lifting structure 202 further includes guide rods 2024 and linear bearings 2025. The number of guide rods 2024 can be the same as the number of support columns 2011 in the second bracket 2014, for example, four. The guide rods 2024 can be fixed one-to-one to the side of the support columns 2011 facing the interior of the second bracket 2014 and extend parallel to the support columns 2011.

[0035] Continue to refer Figure 1 Linear bearings 2025 are slidably mounted on the outside of guide rods 2024 in a one-to-one correspondence. Linear bearings 2025 can slide up and down along the extension direction of guide rods 2024 (i.e., vertical direction Z). The lamp holder assembly 30 is also fixed to the linear bearings 2025. The lifting motor 2021 drives the screw rod body 2022 to cooperate with the linear bearings 2025 to adjust the height of the lamp holder assembly 30.

[0036] Further optional, Figure 2This is a schematic diagram of the structure of a lamp stand assembly provided by an embodiment of the utility model, which can be combined with reference to Figure 1 and Figure 2 In a possible embodiment, the lamp frame assembly 30 further includes a fixing frame 303, which includes two first fixing portions 3031 and a second fixing portion 3032. The two first fixing portions 3031 extend along the first direction X and are arranged along the second direction Y. The second fixing portion 3032 extends along the second direction Y. Both ends of the second fixing portion 3032 abut against and are fixed to the two first fixing portions 3031 respectively. The first direction X is perpendicular to the second direction Y. The first lighting assembly 301 and the second lighting assembly 302 are respectively fixed to the two sides of the first fixing portion 3031 along the first direction X. Along the first direction X, the second fixing portion 303 2 is located between the first lighting assembly 301 and the second lighting assembly 302. The second fixing portion 3032 includes a screw rod receiving hole 30321. The lifting screw rod assembly includes a screw rod body 2022 and a lifting nut 2023. The lifting nut 2023 is sleeved on the outside of the screw rod body 2022 and threadedly connected to the screw rod body 2022. The lifting nut 2023 is fixed in the screw rod receiving hole 30321. The fixing frame 303 also includes a connecting portion 3033. The connecting portion 3033 is located between the first fixing portion 3031 and the support column 2011. The connecting portion 3033 is used to fix the first fixing portion 3031 to the linear bearing 2025.

[0037] like Figure 1 and Figure 2 As shown, the fixing frame 303 is the main frame structure of the lamp frame assembly 30, which is used to fix the first lighting assembly 301 and the second lighting assembly 302. The fixing frame 303 can be an "H"-shaped frame structure, including two first fixing parts 3031 and a second fixing part 3032. The first fixing part 3031 extends along the first direction X, and the second fixing part 3032 extends along the second direction Y. The two first fixing parts 3031 are respectively located at the two ends of the extension direction of the second fixing part 3032. Figure 2 The first fixing portion 3031 is shown to include two fixing rods, and the second fixing portion 3032 is an H-shaped frame structure, but is not limited thereto. This structure is beneficial for improving the firmness of the fixing frame 303 .

[0038] Continue to refer Figure 1 and Figure 2The two sides of the first fixing portion 3031 along the first direction X may refer to the two ends of the first fixing portion 3031 in its extending direction. In the second direction Y, the endpoints of the two first fixing portions 3031 are aligned. The two opposite sides of the first fixing portion 3031 in the first direction X may be defined as a first side and a second side, respectively. The first lighting assembly 301 may be fixed to the first side of the first fixing portion 3031 (the two first fixing portions 3031), and the second lighting assembly 302 may be fixed to the second side of the first fixing portion 3031 (the two first fixing portions 3031), so that the first lighting assembly 301 and the second lighting assembly 302 are arranged along the first direction X.

[0039] In particular, along the first direction X, the second fixing portion 3032 is located between the first lighting assembly 301 and the second lighting assembly 302, and the second fixing portion 3032 is located in the central area of ​​the fixed frame 303. The second fixing portion 3032 includes a screw receiving hole 30321, which extends through the main body of the second fixing portion 3032 along the vertical direction Z. It can also be understood that the screw receiving hole 30321 is a hollowed-out area of ​​the physical structure of the second fixing portion 3032. The screw receiving hole 30321 can be located at the center (or center of gravity) of the entire fixed frame 303. The screw body 2022 of the lifting screw assembly passes through the screw receiving hole 30321, and the lifting nut 2023 is fixed in the screw receiving hole 30321, thereby securing the fixed frame 303 to the lifting screw assembly.

[0040] For further reference, Figure 1 and Figure 2 Along the second direction Y, the distance between the two sides of the first fixing portions 3031 that are spaced apart from each other can be less than the width of the second bracket 2014 in the second direction Y; the extended length of the first fixing portions 3031 can be greater than the width of the second bracket 2014 in the first direction X. The width of the second bracket 2014 in the second direction Y can also be understood as the spacing between two support columns 2011 arranged along the second direction Y, and the width of the second bracket 2014 in the first direction X can also be understood as the spacing between two support columns 2011 arranged along the first direction X. In this arrangement, along the first direction X, the fixing frame 303 extends beyond the second bracket 2014, while along the second direction Y, the fixing frame 303 is located within the frame of the second bracket 2014.

[0041] The fixing frame 303 may further include a connecting portion 3033 , which is located on a side surface of the first fixing portion 3031 facing away from the second fixing portion 3032 along the second direction Y. The connecting portion 3033 is aligned with the linear bearing 2025 along the second direction Y. The connecting portion 3033 is used to fix the first fixing portion 3031 and the linear bearing 2025 , thereby achieving fixation between the lamp holder assembly 30 and the linear bearing 2025 .

[0042] Among them, the frame structures involved in the integrated lighting lamp frame are all metal frame structures, which are not elaborated or limited in the embodiments of the present invention.

[0043] Optional, you can continue to refer to Figure 1 and Figure 2 In some embodiments, the first lighting component 301 includes a first light source fixing plate 3011 and an infrared lamp array 3012, and the infrared lamp array 3012 is installed on one side surface of the first light source fixing plate 3011. The second lighting component 302 includes a second light source fixing plate 3021 and a halogen lamp array 3022, and the halogen lamp array 3022 is installed on one side surface of the second light source fixing plate 3021; ​​the lamp holder assembly 30 also includes a fixed frame 303, the first light source fixing plate 3011 and the second light source fixing plate 3021 are respectively located on opposite sides of the fixed frame 303, and the infrared lamp array 3012 and the halogen lamp array 3022 are both away from the fixed frame 303.

[0044] like Figure 1 and Figure 2 As shown, the illumination assembly may comprise a light source fixing plate and a light source. The first illumination assembly 301 includes a first light source fixing plate 3011 and an infrared lamp array 3012 disposed on a side surface of the first light source fixing plate 3011. The infrared lamp array 3012 may include a plurality of infrared bulbs arranged in an array along a first direction X and a second direction Y. The second illumination assembly 302 includes a second light source fixing plate 3021 and a halogen lamp array 3022 disposed on a side surface of the second light source fixing plate 3021. The halogen lamp array 3022 may include at least two halogen bulbs arranged along the first direction X or the second direction Y. The structure of the fixing frame 303 in the lamp holder assembly 30 is the same as in the above-described embodiment and will not be further described here. The side surface of the first light source fixing plate 3011 on which the infrared lamp array 3012 is not provided is connected to the first side of the first fixing part 3031, and the side surface of the second light source fixing plate 3021 on which the infrared lamp array 3012 is not provided is connected to the second side of the first fixing part 3031, and the infrared lamp array 3012 and the halogen lamp array 3022 are respectively away from the fixing frame 303.

[0045] The arrangement of the light bulbs in the infrared lamp array 3012 and the halogen lamp array 3022 is not limited and can be set by those skilled in the art according to actual needs. By setting the infrared lamp array 3012 and the halogen lamp array 3022, a wide range of adjustment of the light intensity can be achieved, thereby simulating different intensities of sunlight and performing performance tests on the test object under different light intensities. Figure 1 and Figure 2 As shown, the infrared lamp array 3012 can be in a "cross" shaped array, thereby enabling flexible adjustment of the formation of the infrared light spot.

[0046] Further, you can continue to refer to Figure 1and Figure 2 The lamp holder assembly 30 may also include a first angle adjustment assembly 304 and a second angle adjustment assembly 305. The fixed frame 303 is connected to the first light source fixing plate 3011 through the first angle adjustment assembly 304, and is connected to the second light source fixing plate 3021 through the second angle adjustment assembly 305; the first light source fixing plate 3011 includes a first virtual symmetry axis AX1, which is perpendicular to the first direction X. The first angle adjustment assembly 304 drives the first light source fixing plate 3011 to rotate around the first virtual symmetry axis AX1, thereby adjusting the illumination angle of the infrared lamp array 3012; the second light source fixing plate 3021 includes a second virtual symmetry axis (not shown in the figure), which is perpendicular to the first direction X. The second angle adjustment assembly 305 drives the second light source fixing plate 3021 to rotate around the second virtual symmetry axis, thereby adjusting the illumination angle of the halogen lamp array 3022; the first direction X is parallel to the arrangement direction of the first illumination assembly 301 and the second illumination assembly 302.

[0047] like Figure 1 and Figure 2 As shown, the second virtual symmetry axis is arranged opposite to the first virtual symmetry axis AX1. Figure 2 As not shown, both the first virtual symmetry axis AX1 and the second virtual symmetry axis extend along the second direction Y. The first light source fixing plate 3011 is symmetrical about the first virtual symmetry axis AX1 , and the second light source fixing plate 3021 is symmetrical about the second virtual symmetry axis.

[0048] The first light source fixing plate 3011 and the first side of the first fixing portion 3031 are connected via a first angle adjustment assembly 304. The specific structure of the first angle adjustment assembly 304 is not limited. The first angle adjustment assembly 304 controls the rotation of the first light source fixing plate 3011 around its first virtual axis of symmetry AX1 by ±90°. In the initial state, the first light source fixing plate 3011 is at 0°. Rotation around the first virtual axis of symmetry AX1 is defined as upward in the positive direction and downward in the negative direction. When the first light source fixing plate 3011 is at 0°, the illumination plane of the infrared lamp array 3012 is parallel to the vertical direction Z. When the first light source fixing plate 3011 is at -90°, the illumination plane of the infrared lamp array 3012 is perpendicular to the vertical direction Z, and the infrared lamp array 3012 faces the ground. When the first light source fixing plate 3011 is at +90°, the illumination plane of the infrared lamp array 3012 is perpendicular to the vertical direction Z, and the infrared lamp array 3012 faces away from the ground. This allows the illumination angle of the first illumination assembly 301 to be adjusted.

[0049] Accordingly, the second light source fixing plate 3021 and the second side of the first fixing portion 3031 can be connected via a second angle adjustment assembly 305. The specific structure of the second angle adjustment assembly 305 is not limited. The second angle adjustment assembly 305 can control the second light source fixing plate 3021 to rotate ±90° about its second virtual axis of symmetry. In the initial state, the second light source fixing plate 3021 is at 0°. Rotation about the second virtual axis of symmetry is defined as upward in a positive direction and downward in a negative direction. When the second light source fixing plate 3021 is at 0°, the illumination plane of the halogen lamp array 3022 is parallel to the vertical direction Z. When the first light source fixing plate 3011 is at -90°, the illumination plane of the halogen lamp array 3022 is perpendicular to the vertical direction Z and faces the ground. When the first light source fixing plate 3011 is at +90°, the illumination plane of the halogen lamp array 3022 is perpendicular to the vertical direction Z and faces away from the ground. In this way, the illumination angle of the second illumination component 302 can be adjusted.

[0050] By controlling the illumination angle of the first illumination component 301 or the second illumination component 302 , different positions of the object to be tested can be illuminated with different illumination intensities, thereby simulating the situation where the object to be tested is exposed to sunlight in more actual application scenarios.

[0051] Exemplarily, the first angle adjustment component 304 and the second angle adjustment component 305 can be an electric angle adjustment mechanism or a manual angle adjustment mechanism. The electric angle adjustment component can include a reduction motor 3041, a driving gear 3042 and a driven gear 3043. The reduction motor 3041 is connected to the driving gear 3042 in a transmission manner. The driving gear 3042 is meshed with the rack of the driven gear 3043. The driven gear 3043 can be semicircular, wherein the arc-shaped edge portion is provided with a rack, and the straight edge portion is fixed to the light source fixing plate. The rotation of the light source fixing plate can be controlled by controlling the operation of the reduction motor 3041. The manual angle adjustment mechanism can include a rotating handle 3051 and a right-angle reducer 3052. The rotating handle 3051 is connected to the right-angle reducer 3052 and the light source fixing plate in a transmission manner respectively. The rotation of the light source fixing plate can be controlled by adjusting the rotating handle 3051. The right-angle reducer 3052 plays an auxiliary rotation effect, thereby achieving the purpose of saving effort.

[0052] Optionally, the first angle adjustment component 304 and the second angle adjustment component 305 can both be electric angle adjustment mechanisms, or can both be manual angle adjustment mechanisms, or one can be an electric angle adjustment mechanism and the other can be a manual angle adjustment mechanism. This embodiment of the utility model is not limited to this. Figure 2 In the figure, it is exemplified that the first angle adjustment component 304 is an electric angle adjustment mechanism and the second angle adjustment component 305 is a manual angle adjustment mechanism, but the present invention is not limited thereto.

[0053] Optional, you can continue to refer to Figure 2 The lamp holder assembly 30 may further include a rotation angle indicating assembly 306, and the rotation angle indicating device rotates with the first light source fixing plate 3011 and / or the second light source fixing plate 3021 to display the rotation angle of the first light source fixing plate 3011 and / or the second light source fixing plate 3021.

[0054] The lamp holder assembly 30 may include two rotation angle indication assemblies 306. The rotation angle indication assembly 306 may include an angle disk and a pointer. The pointer rotates with the light source fixing plate to display the current rotation angle of the light source fixing plate on the angle disk, so as to facilitate the tester to control the lighting angle of the lighting assembly.

[0055] Optionally, the integrated lighting lamp stand also includes a controller (not shown in the figure), which is electrically connected to the first angle adjustment component 304 and the second angle adjustment component 305 respectively. The controller receives angle adjustment information input by the user and controls the operation of the first angle adjustment component 304 or the second angle adjustment component 305 according to the angle adjustment information.

[0056] The test system may include a display screen, and the user can input an angle adjustment signal on the display screen. After the controller receives the angle adjustment information, it controls the angle adjustment component to operate according to the angle adjustment information, thereby adjusting the rotation angle of the first lighting component 301 or the second lighting component 302.

[0057] Optionally, the controller can be connected to the rotating shaft 101 of the base turntable 10 via a rotary motor. The controller can receive lighting mode information input by the user and control the rotation of the rotating shaft 101 based on the lighting mode information, thereby switching between the first lighting assembly 301 and the second lighting assembly 302. The controller can also be electrically connected to the lifting motor 2021. The controller receives height adjustment information input by the user and controls the operation of the lifting screw assembly based on the height adjustment information, thereby adjusting the height of the lamp stand assembly 30.

[0058] By adopting the integrated illumination lamp stand in the embodiment of the present invention, the adjustment accuracy of the light intensity can be controlled within ±1W / ㎡.

[0059] Further optional, you can continue to refer to Figure 1 The integrated illumination lamp holder further includes a plurality of first pulleys 40, which are mounted on a surface of the base turntable 10 on a side facing away from the bracket body 20. The plurality of first pulleys 40 can be evenly distributed on the bottom surface of the base turntable 10. By providing the first pulleys 40, the integrated illumination lamp holder can be freely moved.

[0060] Continue to refer Figure 1The orthographic projection of the support body 20 on the plane where the base turntable 10 is located can be located within the coverage area of ​​the base turntable 10. A plurality of second pulleys 50 can be installed at the bottom of the support body 20 (i.e., the bottom of the support frame 201). The second pulleys 50 can be installed one by one on the side of the support column 2011 close to the base turntable 10, and the second pulleys 50 can contact the upper surface of the base turntable 10. When the support body 20 rotates, the second pulleys 50 can slide on the base turntable 10, thereby assisting the rotation of the support body 20.
