Abstract
Description
Technical Field
[0001] This utility model relates to the field of luminance testing technology, specifically to a CCD luminance meter. Background Technology
[0002] Luminance is a physical quantity that describes the subjective perception of the luminous intensity of a light-emitting or reflective surface by the human eye. Its SI unit is the candela (square meter). This parameter is derived by calculating the luminous flux per unit solid angle after differentiating the area of the light source. Its value is closely related to the viewing angle and surface radiation characteristics. In the field of display technology, luminance control directly affects the perceived brightness of the screen. For example, CRT monitors achieve luminance modulation by adjusting the electron beam intensity. Compared to brightness, which is more suitable for measuring point light sources, luminance is more appropriate for characterizing the visual perceived intensity of a light-emitting or reflective surface with an area. Some keyboards contain decorative or illuminated light-emitting elements. During the keyboard manufacturing process, the luminance of these light-emitting components needs to be tested to prevent excessive light from illuminating the components.
[0003] However, in the existing technology, when testing the brightness of a keyboard, each key is tested one by one at a fixed interval. However, a person's height affects the height of their line of sight, and the brightness effect will be different for people of different heights when using the keyboard, making the brightness test at a fixed interval inaccurate. Summary of the Invention
[0004] The purpose of this invention is to provide a CCD luminance meter, which has the advantage of adjusting the height and distance of luminance testing to test the luminance of a keyboard at different spacings, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a CCD luminance meter, comprising an installation component, a testing component, and a placement component. The testing component is disposed within the installation component for testing the keyboard's luminous performance, and the placement component is disposed on the installation component for placing the keyboard and rotating it for testing.
[0006] Furthermore, the test assembly includes a rectangular plate, a slide rail, a screw, an adjusting block, two concave plates, two sliders, two connecting blocks, a motor, and an adjusting frame. The rectangular plate is disposed within the mounting assembly. The slide rail is fixedly mounted on one outer wall of the rectangular plate. The screw is rotatably mounted within the slide rail. The adjusting block is threaded onto the screw. Both concave plates are disposed within the mounting assembly. The two sliders are slidably mounted within the two concave plates. The two connecting blocks are fixedly mounted on the two sliders. The motor is fixedly mounted on the top of the slide rail, and its output end is fixedly connected to the top of the screw. The adjusting frame is fixedly mounted on the outer wall of the adjusting block and is fixedly connected to the two connecting blocks.
[0007] Furthermore, the cross-sections of the two concave plates are C-shaped, and the cross-sections of the two sliders are I-shaped.
[0008] Furthermore, the installation assembly includes a mounting frame, a fixed cabinet, a mounting plate, a mounting cabinet, and a display terminal. The fixed cabinet is fixedly mounted on the mounting frame, the mounting plate is fixedly mounted on the top of the fixed cabinet, the mounting cabinet is fixedly mounted on the top of the mounting plate, the display terminal is fixedly mounted on the mounting cabinet, the rectangular plate is fixedly mounted on one inner wall of the mounting cabinet, the concave plate is fixedly mounted on one inner wall of the mounting cabinet, and a rectangular opening is provided on one outer wall of the mounting cabinet.
[0009] Furthermore, both the fixed cabinet and the installation cabinet are equipped with flip-up cabinet doors.
[0010] Furthermore, a pull-out keyboard is slidably installed on the fixed cabinet.
[0011] Furthermore, the placement assembly includes a second motor, a first gear, a rotating column, a second gear, a turntable, and two placement bases. The second motor is fixedly installed on the bottom inner wall of the fixed cabinet. The first gear is fixedly installed on the output end of the second motor. The rotating column is rotatably installed on the mounting plate. The second gear is fixedly sleeved on the rotating column. The first gear and the second gear mesh with each other. The turntable is fixedly installed on the top of the rotating column. Both placement bases are fixedly installed on the top of the turntable.
[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0013] This invention, through the setting of a testing component, involves opening the mounting cabinet, fixing the imaging luminance and colorimeter on the adjustment frame, and then closing the mounting cabinet again. Starting motor one drives a screw to rotate, which in turn moves an adjusting block. The adjusting block slides within a slide rail, causing the adjustment frame and the imaging luminance and colorimeter to move. As the adjustment frame moves, a connecting block moves, which in turn moves a slider. The slider slides within a concave plate, limiting the movement trajectory of the adjustment frame. The adjustment frame moves within the mounting cabinet, offering the advantage of adjusting the height and distance for luminance testing and allowing for testing of keyboard luminance at different intervals.
[0014] This invention, through the setting of a placement component, places the keyboard on a placement base. Then, motor two is activated, driving gear one to rotate. Gear one meshes with gear two, causing gear two to rotate. This rotation of gear two, in turn, drives a rotating column, which in turn drives a turntable. The turntable rotates the placement base and the placed keyboard, moving the keyboard into the mounting cabinet. The idle placement base is then moved out of the mounting cabinet, allowing the keyboard to be placed back on the placement base. The keyboard, now inside the mounting cabinet, is then subjected to luminance testing. This invention offers the advantage of allowing for both placement and luminance testing of keyboards, and also allows for rotating testing. Attached Figure Description

The adjustment frame 209 is fixedly mounted on the top of the slide rail 202. The adjustment frame 209 is fixedly installed on the outer wall of the adjustment block 204. The adjustment frame 209 is fixedly connected to two connecting blocks 207. More specifically, the mounting cabinet 104 is opened, the imaging luminance meter is fixedly installed on the adjustment frame 209, and the mounting cabinet 104 is closed again. The motor 208 is started, and the motor 208 drives the screw 203 to rotate. The screw 203 drives the adjustment block 204 to move. The adjustment block 204 slides in the slide rail 202. The adjustment block 204 drives the adjustment frame 209 and the imaging luminance meter to move. When the adjustment frame 209 moves, it drives the connecting blocks 207 to move. The connecting blocks 207 drive the slider 206 to move. The slider 206 slides in the concave plate 205 to limit the movement trajectory of the adjustment frame 209. The adjustment frame 209 moves in the mounting cabinet 104.

[0026] In addition, the cross-sections of the two concave plates 205 are C-shaped, and the cross-sections of the two sliders 206 are I-shaped.
[0027] like Figure 1 As shown, the installation assembly 1 includes a mounting frame 101, a fixed cabinet 102, a mounting plate 103, a mounting cabinet 104, and a display terminal 105. The fixed cabinet 102 is fixedly mounted on the mounting frame 101, the mounting plate 103 is fixedly mounted on the top of the fixed cabinet 102, the mounting cabinet 104 is fixedly mounted on the top of the mounting plate 103, the display terminal 105 is fixedly mounted on the mounting cabinet 104, the rectangular plate 201 is fixedly mounted on one inner wall of the mounting cabinet 104, the concave plate 205 is fixedly mounted on one inner wall of the mounting cabinet 104, and a rectangular opening is provided on one outer wall of the mounting cabinet 104.
[0028] In addition, both the fixed cabinet 102 and the installation cabinet 104 are equipped with flip-up cabinet doors.
[0029] In addition, a pull-out keyboard is slidably installed on the fixed cabinet 102.
[0030] like Figure 1 As shown, in some embodiments, the placement assembly 3 includes a second motor 301, a first gear 302, a rotating column 303, a second gear 304, a turntable 305, and two placement bases 306. The second motor 301 is fixedly installed on the bottom inner wall of the fixed cabinet 102. The first gear 302 is fixedly installed on the output end of the second motor 301. The rotating column 303 is rotatably installed on the mounting plate 103. The second gear 304 is fixedly sleeved on the rotating column 303. The first gear 302 and the second gear 304 mesh with each other. The turntable 305 is fixedly installed on the top of the rotating column 303. Both placement bases 306 are fixedly installed on the top of the turntable 305. More specifically, the keyboard is placed on the placement base 306. At this point, motor 2 301 is started, which drives gear 1 302 to rotate. Gear 1 302 meshes with gear 2 304, causing gear 2 304 to rotate. Gear 2 304 rotates and drives rotating column 303 to rotate. Rotating column 303 drives turntable 305 to rotate. Turntable 305 drives placement base 306 and the keyboard to rotate. Turntable 305 rotates the keyboard into installation cabinet 104. At this time, the idle placement base 306 moves out of installation cabinet 104, and the keyboard can be placed back on placement base 306. The keyboard rotated into installation cabinet 104 is then tested for luminance. This method has the advantage of testing the luminance of keyboards by placing them and performing rotational tests.
[0031] Working principle:
[0032] Step 1: Place the keyboard on the placement base 306. Start motor 2 301, which drives gear 1 302 to rotate. Gear 1 302 meshes with gear 2 304, causing gear 2 304 to rotate. This rotation of gear 2 304 drives the rotating column 303 to rotate, which in turn drives the turntable 305 to rotate. The turntable 305 then rotates the placement base 306 and the keyboard, moving the keyboard into the mounting cabinet 104. The freed placement base 306 is then moved out of the mounting cabinet 104, allowing the keyboard to be placed back on the placement base 306. The keyboard, now inside the mounting cabinet 104, is then used for luminance testing.
[0033] Step 2: Adjustment and Movement. Open the mounting cabinet 104, fix the imaging luminance and colorimeter on the adjustment frame 209, and close the mounting cabinet 104 again. Start the motor 208. The motor 208 drives the screw 203 to rotate, and the screw 203 drives the adjustment block 204 to move. The adjustment block 204 slides in the slide rail 202, and the adjustment block 204 drives the adjustment frame 209 and the imaging luminance and colorimeter to move. When the adjustment frame 209 moves, it drives the connecting block 207 to move. The connecting block 207 drives the slider 206 to move. The slider 206 slides in the concave plate 205 to limit the movement trajectory of the adjustment frame 209. The adjustment frame 209 moves in the mounting cabinet 104 to adjust the distance between the imaging luminance and colorimeter and the keyboard, and test the luminance at different distances.
