[0018] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] The relative arrangement of components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
[0020] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.
[0021] Additionally, descriptions of well-known structures, functions, and configurations may be omitted for clarity and conciseness.One of ordinary skill in the art will recognize that various changes and modifications may be made to the examples described herein without departing from the spirit and scope of the present disclosure.
[0022] Technologies, methods, and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and equipment should be considered part of the authorization specification.
[0023] In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0024] Example 1 Embodiment 1 of the present invention is a device for measuring the lighting area and illumination level of an oral lamp, comprising a test screen 2 with grid information located above a base 1, a clamping assembly 3 for fixing the oral lamp being provided on one side of the base 1, a sliding assembly 4 being provided above the test screen 2, the sliding assembly 4 clamping a probe 50 of an illuminance meter 5 and a displacement sensor 7 for monitoring grid points 20, the probe 50 being used to measure the illumination of the oral lamp at each grid point 20 of the test screen 2, and the test screen 2 recording the coordinates of a plurality of grid points and the illumination information of the corresponding grid points.
[0025] Reference Figures 1 to 3In the present application, the illumination area and illumination level of the oral lamp to be tested are mainly determined by first measuring the illumination value of each grid point 20 through a measuring device. The test screen 2 will record the coordinates of each grid point 20 and the illumination value of the corresponding grid point 20. At the same time, the information processing module and the control module in the test screen 2 will screen the illumination inner areas A and B in turn according to the illumination value, so as to determine whether each area meets the illumination conditions of the corresponding area. At the same time, the 75% maximum illumination iso-illuminance lines, the 50% maximum illumination iso-illuminance lines, and the 10% maximum illumination iso-illuminance lines are presented in a visual form on the test screen 2.
[0026] Specifically, the probe 50 of the illuminometer 5 is mainly driven by the sliding assembly 4 to move the position of each grid point 20 in the measuring screen, so that the probe 50 can detect the illuminance of each grid point 20 in the measuring screen without manual detection and recording.
[0027] Among them, the grid points 20 of the test screen 2 are points obtained by the intersection of uniformly distributed horizontal grids and longitudinal grids, and the spacing of each grid point 20 meets the measurement interval in YY / T 1120-2021. At the same time, during measurement, the sliding component 4 drives the probe 50 of the illuminance meter 5 to first measure the grid points 20 of each row, and then move to the grid points 20 of the next row, and measure the illuminance values of each grid point 20 in turn. The position of the displacement sensor 7 is on the same vertical axis as the probe 50. On the one hand, it determines the moving direction of the probe 50 and improves the positioning accuracy of the probe 50 when measuring at this grid point 20. On the other hand, it is convenient to transmit the coordinate information of the same grid point 20 to the test screen 2 for collection. After the measurement is completed, the sliding component 4 is moved out of the top of the test screen 2.
[0028] In some preferred embodiments, the clamping assembly 3 includes an electric telescopic rod 34 located on one side of the base 1, the telescopic end of the electric telescopic rod 34 is provided with a lifting plate 30 connected to the clamping frame 31, the side plates of the clamping frame 31 are provided with a penetrating threaded rod 32, and the end of the threaded rod 32 located in the clamping frame 31 is provided with a clamping plate 33.
[0029] The clamping assembly 3 is mainly used to clamp the oral cavity lamp to be tested. The oral cavity lamp to be tested is placed in the clamping frame 31. Figure 4 The clamping plates 33 provided around the clamping frame 31 are always tightly clamped around the periphery of the oral light to be tested under the action of the threaded rod 32, ensuring that the clamping plates 33 do not fall off during the illumination test. At the same time, the movement of the clamping plates 33 in the clamping frame 31 facilitates the utilization rate of the clamping device. The four plates of the clamping frame 31 are preset with threaded holes adapted to the threaded rod 32.
[0030] The electric telescopic rod 34 is a prior art, and the height of the lifting plate 30 and the clamping frame 31 is mainly controlled by an external controller, so that the distance between the lamp surface at the bottom of the oral lamp to be tested and the surface of the probe 50 meets the test requirements.
[0031] In some preferred embodiments, the sliding assembly 4 includes a sliding frame composed of two first vertical plates 40 and a second vertical plate 47 located between the first vertical plates 40, a first screw rod 41 connected to a stepper motor 43 is provided on the side of the first vertical plate 40 away from the second vertical plate 47, a first moving block 42 is provided on the outer periphery of the first screw rod 41, a fixing rod 48 is provided on the top of the second vertical plate 47, a second moving block 45 is provided on the outer periphery of the fixing rod 48, and a second screw rod 44 is provided between the first moving block 42 and the second moving block 45.
[0032] Specifically, refer to Figure 2 and Figure 3 The sliding assembly 4 is mainly composed of a sliding frame with a three-sided structure formed between the first vertical plate 40 and the second vertical plate 47. The first screw rod 41 is provided on the opposite side of the second vertical plate 47. The bottom of the first screw rod 41 may be provided with a connecting plate (not shown in the figure). The connecting plate is higher than the surface of the test screen 2, and the two first vertical plates 40 away from the second vertical plate 47 are connected, thereby increasing the overall stability of the entire sliding frame. The first moving block 42 arranged on the periphery of the first screw rod 41 connects the second screw rod 44 through the second moving block 45. The second moving block 45 is sleeved on the periphery of the fixed rod 1 48, so that the first screw rod 41 drives the first moving block 42 to move, so that the first moving block 42 drives the second screw rod 44 and the second moving block 45 to move horizontally, ensuring that the illumination of each row of grid points 20 is measured. The end of the second screw rod 44 away from the first moving block 42 is connected to the output end of the stepper motor 2 440.
[0033] It should be noted that the connection between the first moving block 42 and the second screw rod 44 does not affect its connection with the first screw rod 41; the second screw rod 44 horizontally penetrates the upper part of the second moving block 45, and the fixed rod 1 48 vertically penetrates the lower part of the second moving block 45. The penetration parts of the two are perpendicular to each other and are not connected, so as not to affect the respective movement of the first screw rod 41 and the second screw rod 44. At the same time, the first vertical plate 40 away from the stepping motor 1 43 is provided with a bearing connected to the end of the first screw rod 41 to provide a rotation space for it; the first moving block 42 and the end of the second screw rod 44 are also provided with bearings to provide a rotation space for the second screw rod 44.
[0034] Stepper motor 1 43 and stepper motor 2 440 provide driving force for the first screw rod 41 and the second screw rod 44 respectively. When stepper motor 1 works, stepper motor 2 440 does not work; when stepper motor 2 440 works, stepper motor 1 43 does not work, so that the probe 50 can measure each row of grid points 20 one by one.
[0035] At the same time, fixed plates are respectively provided at the bottom of stepper motor 1 43 and stepper motor 2 440. The fixed plate below stepper motor 1 43 is connected to the first vertical plate 40, and the fixed plate below stepper motor 2 440 is slidably connected to the second vertical plate 47. At the same time, an inclined support plate is provided below the second vertical plate 47 and is slidably connected to the second vertical plate 47, so that the second screw rod 44 drives stepper motor 2 440 and the fixed plate and support plate below it to slide on the second vertical plate 47. A moving rod is provided at the connecting part so that it moves on the moving rod to ensure the stability of stepper motor 2 440 during the movement.
[0036] In some preferred embodiments, a third movable block 46 is provided on the outer periphery of the second screw rod 44, a placement groove 460 is provided on the surface of the third movable block 46, a push plate 462 symmetrically connected to a spring 463 is provided on the inner side of the placement groove 460, and a fixing rod 461 is also provided in the placement groove 460, which passes through both ends of the push plate 462 respectively; the displacement sensor 7 is located at the bottom of the third movable block 46 and is on the same vertical axis as the probe 50.
[0037] Specifically, refer to Figure 5 The probe 50 of the illuminometer 5 is mainly located in the placement groove 460 on the surface of the third moving block 46. The push plate 462 is assembled with the spring 463 and the second fixing rod 461 to place the probe 50 in the placement groove 460, and the spring 463 is compressed at the same time, so that the push plate 462 is in close contact with the outer periphery of the probe 50, ensuring that the displacement is prevented during the process of moving and measuring the illuminance. At the same time, when installing the probe 50 of the illuminometer 5, ensure that the probe 50 of the illuminometer 5 and the displacement sensor 7 are on the same vertical axis, so that the position information of each grid point 20 corresponds to the corresponding illuminance value one by one to prevent errors. At the same time, the inner sides of the push plate 462 and the clamping plate 33 are respectively provided with a buffer layer 6 to avoid damage to the outer wall of the oral lamp to be tested.
[0038] In some preferred embodiments, the test screen 2 is located at the bottom of the sliding frame, the test screen 2 has a plurality of grid points 20, each grid point 20 is provided with an LED two-color indicator light, the first moving block 42 and the second moving block 45 drive the second screw rod 44 to move horizontally, and the second screw rod 44 drives the third moving block 46 to drive the probe 50 to move longitudinally; The height difference between the probe 50 and the oral lamp is 700 mm; The first moving block 42 and the third moving block 46 move at a linear interval not exceeding 5 mm respectively.
[0039] The test screen 2 is provided with a receiving module, an information processing module and a control module. The receiving module is used to obtain the illuminance value data of the transmitting end in the illuminance meter 5 and the displacement sensor 7 respectively; the information processing module is used to determine whether the illuminance value of each grid point 20 meets 75%, 50% or 10% of the maximum illuminance value; the control module is used to turn on or off the LED indicator light of the corresponding grid point 20.
[0040] Specifically, refer to Figure 6 Each grid point 20 is provided with an LED two-color indicator light, which is divided into light one and light two. The first screw rod 41 and the second screw rod 44 respectively work to drive the third moving block 46 to drive the probe 50 to measure the illumination of each grid point 20, so that the receiving module in the test screen 2 obtains the coordinate information of the grid point 20 and the illumination value information of the corresponding grid point 20. This information is then filtered by the information processing module in the illumination inner area A and area B to determine whether the illumination value of the grid point 20 in each area meets 75% or 50% or 10% of the maximum illumination value. The control module then turns on or off light one or light two in the LED two-color indicator light according to the illumination value of each area, thereby lighting up the 75% maximum illumination iso-illuminance line, the 50% maximum illumination iso-illuminance line and the 10% maximum illumination iso-illuminance line in the test screen 2. There is no need to manually record the illumination values of each existing measurement interval and no need to manually draw, and the visualization degree of each maximum illumination iso-illuminance line is high.
[0041] Example 2 A method for measuring the lighting area and illumination level of an oral light, using a device for measuring the lighting area and illumination level of an oral light in Example 1, comprising the following steps: S1: Screen the illumination values of all grid points and select the grid point 20 with the largest illumination value as the Lmax point; S2: Screen the grid points with illumination values greater than or equal to 75%×Lmax, and light up the first LED dual-color indicator light of the corresponding grid point; S3: Define the lighting inner zone A; The center point of the A zone is the Lmax point. The control module divides the oval outer frame with a major axis of 50 mm and a minor axis of 25 mm according to the center point of the A zone, and lights up the second LED dual-color indicator light corresponding to the grid point 20 of the oval outer frame; Determine whether the lighting point of the LED dual-color indicator light of lamp 2 is included in the lighting range of the LED dual-color indicator light of lamp 1 in step S2. If so, the illumination condition of zone A is met; If not, move the position of area A so that point Lmax is always located in area A, and find out whether the lighting point of lamp 2 is included in the lighting range of the LED dual-color indicator light of lamp 1 in step S2. If found, the center point of area A is determined as the final center point, and the illumination condition of area A is met; If not, the illumination condition of zone A is not met; The illumination condition at this time refers to the "illuminance in zone A should not be less than 75% of the maximum illumination Lmax" in the YY / T 1120-2021 "Dental Oral Light" standard.
[0042] S4: Mark the 75% maximum illumination iso-illuminance line: Turn off the LED dual-color indicators of all lamps 2 in step S3, and at the same time, turn the outermost lamp 1 of the LED dual-color indicators of lamp 1 to lamp 2, turn off the LED dual-color indicators of the remaining lamps 1, and lamps 2 form an equal illumination line of 75% maximum illumination, that is, illuminate the inner zone A; S5: Mark the 50% maximum illumination iso-illuminance line: Screen the grid points with illumination values greater than or equal to 50%×Lmax, and light up the first LED dual-color indicator light of the corresponding grid point; Determine whether the outer boundary of the area formed by the multiple lights 1 is on or outside the ellipse with a major axis of 80 mm and a minor axis of 40 mm. If so, the LED two-color indicator light in the outer circle of the outer boundary of the area formed by the multiple lights 1 is switched from light 1 to light 2, and the remaining lights 1 are turned off. Lights 2 form an equal illumination line of 50% maximum illumination, that is, illuminate the inner area B, and the illumination condition of area B is met; If it does not exist, the illumination condition of area B is not met.
[0043] The illumination condition here means that "the outer boundary of zone B should be on or outside the ellipse with a major axis of 80 mm and a minor axis of 40 mm".
[0044] S6: Mark the 10% maximum illumination iso-illuminance line: Screen the grid points with illuminance values greater than or equal to 10%×Lmax, light up the second LED dual-color indicator light of the outermost circle corresponding to the grid point, and form an 10% maximum illuminance equal illuminance line, that is, the lighting inner zone C; S7: Light up one of the LED two-color indicator lights at the grid point corresponding to the Lmax point.
[0045] After step S7 is completed, three elliptical lines are obtained in the test screen 2, which are the 75% maximum illumination iso-illuminance line, the 50% maximum illumination iso-illuminance line, and the 10% maximum illumination iso-illuminance line.
[0046] It should be noted that the specific colors of light one and light two are selected according to actual conditions to ensure that the distinction between the two is significant.
[0047] The test screen 2 mainly uses the information processing module to judge and analyze the coordinates of each grid point 20 and the illumination value of the corresponding grid point 20, first selects the maximum illumination value, then screens the grid point 20 of 75%×Lmax, and lights one of the LED two-color indicator lights in the grid point 20. The information processing module calculates an elliptical outer frame with a major axis of 50mm and a minor axis of 25mm. The control module lights up the second light of the LED two-color indicator light in the grid point 20 of the elliptical outer frame to determine whether the lit light one is within the range of the lit light two, which is used to calibrate whether the A area of the oral lamp to be tested meets the illumination conditions; then screen the 50%×Lmax and 10%×Lmax grid points 20 in turn, divide the B area, analyze whether the B area meets the conditions, and finally obtain the visualized 75% maximum illumination iso-illuminance lines, 50% maximum illumination iso-illuminance lines, and 10% maximum illumination iso-illuminance lines, with reference to Figure 7 .
