Description

Technical Field

[0001] The invention belongs to the technical field of measurement, and provides an illuminance measuring device which has no limitation on illuminance measurement direction, does not rely on an external power supply, and can simulate actual ambient light, and particularly relates to a multi-directional panoramic illuminance measuring device. Background Art

[0002] Existing illuminance measuring devices have exposed many shortcomings in practical applications. Most traditional illuminance measuring devices can only measure in a single direction or within a limited angle range, which leads to one-sided measurement results and cannot truly reflect the complex and changeable lighting conditions in the actual environment.

[0003] On the other hand, these devices usually need to rely on an external power supply to work properly, which will bring great inconvenience and limitations to the measurement work in some specific measurement scenarios, such as remote outdoor areas, temporary measurement environments, or places with inconvenient power supply.

[0004] In addition, existing illuminance measurement devices generally lack the ability to simulate actual ambient light. In real life, ambient light conditions are diverse, including natural light during the day, moonlight at night, and light produced by different combinations of indoor lamps. These different ambient light conditions will have a significant impact on the illumination of objects, and existing devices cannot simulate these complex ambient light changes, resulting in large deviations between the illuminance measurement results performed in laboratories or specific environments and the actual application scenarios, and unable to accurately evaluate the performance and effects of the lighting system in a real environment. A new type of measurement device is needed to solve the above problems. Summary of the invention

The fan-shaped gear is meshed with the gear two, and the gear two is meshed with the built-in rack. The gear two is also meshed with the partially toothed internal gear. The gear two and the gear three are correspondingly arranged, and a linkage rod is fixedly inserted between them. The extension plate two is provided with a half-fan gear meshed with the gear three. The motor one is also used for adjusting the angle of the extension plate two. The extension plate one and the extension plate two are correspondingly arranged, and they are displaced simultaneously. A damping uniform rotator is provided between their heads, and the damping uniform rotator is used for uniform speed rotation of the illuminance meter. The kinetic energy engine is arranged on a side of the extension plate, and includes a device body, a P-shaped rod, a roller, a pressure-sensitive power generation block, a pin and a mounting hole. The roller is rotatably mounted on one end of the P-shaped rod, and the roller contacts the extension plate. The other end of the P-shaped rod is connected to the pressure-sensitive power generation block. The pressure-sensitive power generation block is connected to an external circuit through the pin, and is used to convert the kinetic energy of the extension plate into electrical energy. The ambient light simulation mechanism comprises a disc, an annular internal gear, a light bulb, a wheel groove, a fourth gear, a second motor, a pulley and a third motor; The disc is provided with an annular internal gear, which meshes with gear four, which is connected to motor three, which is used to drive the annular internal gear to rotate. The annular internal gear is provided with multiple light bulbs, which in turn drive the light bulbs to rotate, so as to simulate different ambient lights. A plurality of pulleys are provided at the bottom of the annular internal gear, which cooperate with the disc to support the disc and make it rotate more smoothly. Motor two is provided on the disc to drive the disc to rotate so as to adjust the position of the angle adjustment mechanism, and the wheel groove is used for the extension and articulation of part of the toothed internal gear.

[0007] As a preferred solution of the present invention, further, the extension plate 1 and the extension plate 2 are connected by a hinge, and an angle limiting device is provided at the connection to limit the angle range between the extension plate 1 and the extension plate 2.

[0008] As a preferred solution of the present invention, further, the hollow cover is arranged on the outside of the partially toothed internal gear, the built-in rack, gear one, gear two and gear three to protect the internal gear structure, and an inspection hole is arranged on the hollow cover.

[0009] As a preferred solution of the present invention, further, when the motor 2 is working, the motor 3 stops working, and when the motor 3 is working, the motor 2 stops working.

[0012] The beneficial effects of the present invention are: The multi-directional panoramic illuminance measuring device of the present invention adopts a unique angle adjustment mechanism, which drives a series of gear transmissions through a motor to drive the extension plate and the illuminance meter installed thereon to perform all-round angle adjustment in the horizontal direction.

[0013] The device innovatively sets up a kinetic energy generator. During the rotation of the extension plate 1, its side surface contacts the roller of the kinetic energy generator, driving the roller to rotate, and then the pressure-sensitive power generation block produces pressure changes through the P-shaped rod, converting the kinetic energy of the extension plate 1 into electrical energy. This electrical energy is transmitted to the energy storage device through pins for storage, or directly powers other components of the device, realizing the partial self-powering function of the device. This design gets rid of the dependence on traditional external power supplies, which not only reduces the cost of use, but also greatly improves the convenience of use of the device in various scenarios, especially in some remote areas or places where external power supply is inconvenient, and illumination measurement work can be carried out normally.

[0014] The ambient light simulation mechanism is a major feature of the present invention. Motor 3 drives the annular internal gear to rotate, causing multiple light bulbs installed on the annular internal gear to rotate accordingly, which can simulate dynamic lighting effects such as sunlight movement. At the same time, the brightness and color temperature of the light bulbs can be accurately adjusted through the controller. According to different actual needs, various complex ambient light conditions can be simulated, such as natural light at different times of the day and lighting environment at night. This ability to simulate actual ambient light makes it possible to be closer to the real scene when performing illuminance measurement, providing more reliable and effective data basis for lighting design, evaluation and other work, and helping to more accurately evaluate the performance and effect of the lighting system in the actual environment.

[0022] The hollow cover 106 is arranged outside the partially toothed internal gear 108, the built-in rack 109, the gear 1 110, the gear 2 111 and the gear 3 115 to protect the internal gear structure, and an inspection hole is arranged on the hollow cover 106.

[0023] When the motor 2 206 is working, the motor 3 208 stops working, and when the motor 3 208 is working, the motor 2 206 stops working.

[0024] An energy storage device is provided on the device body 1131 of the kinetic energy generator 113 for storing the electric energy generated by the pressure-sensitive power generation block 1134 and for supplying power to other components of the device.

[0025] It also includes a controller, which is connected to the pin 1135 of the light meter 101, motor 1 114, motor 206, motor 3 208, and kinetic energy generator 113, and is used to receive the measurement data of the light meter 101, and control the operation of motor 1 114, motor 206, motor 3 208 and the storage and distribution of the electric energy generated by the kinetic energy generator 113.

[0026] Workflow: S1. Initialization preparation Before using the device, the operator needs to conduct a visual inspection of all components to ensure that there is no physical damage to all components and that the connections are firm. Check key components such as the motor, gears, and light bulb 203 to confirm that they are installed correctly and have no signs of looseness. Check the power of the energy storage device. If the power is insufficient, charge it in advance.

[0027] According to the measurement task requirements, the controller sets relevant parameters, sets the measurement range and accuracy requirements of the illuminance meter 101, determines the scene of ambient light simulation, such as simulating indoors during the day and outdoors at night, and then sets the brightness and color temperature of the bulb 203 and the rotation speed and angle range of the motor.

[0028] S2. Illuminance measurement process Start the angle adjustment mechanism 1: turn on the power of the device, the controller sends a command to start the motor 114, the motor 114 drives the gear 110 connected to it to rotate, and the gear 110 drives the annular outer gear 104 meshing with it to rotate. Since the hollow cover 106 is sleeved inside the annular outer gear 104 and the fan gear 107 is fixed in the hollow cover 106, the rotation of the annular outer gear 104 drives the fan gear 107 to rotate synchronously.

[0029] The sector gear 107 meshes with the gear 2 111, and the gear 2 111 meshes with the built-in rack 109 and the partially toothed internal gear 108 covering the inner wall of the hollow cover 106. Such a transmission structure enables the gear 2 111 to achieve complex motion transmission during the rotation process. The gear 2 111 is connected to the gear 3 115 through a linkage rod, driving the gear 3 115 to rotate, and then meshing with the half-sector gear on the extension plate 2 112, so that the extension plate 2 112 starts to rotate. Since the extension plate 1 103 and the extension plate 2 112 are correspondingly arranged and can be displaced at the same time, the extension plate 103 moves accordingly, and the illuminance meter 101 installed on the extension plate 1 103 is adjusted in the horizontal direction. In this process, the damping uniform rotator 102 between the extension plate 1 103 and the extension plate 2 112 head plays a role to ensure that the illuminance meter 101 rotates at a uniform speed, thereby realizing multi-directional illuminance measurement. The illuminance meter 101 converts the real-time measured light intensity data into an electrical signal and transmits it to the controller.

[0030] During the rotation of the extension plate 103, its side surface contacts the roller 1133 of the kinetic energy generator 113 and drives the roller 1133 to rotate. The roller 1133 causes the pressure-sensitive power generation block 1134 to produce pressure changes through the P-shaped rod 1132. Based on the piezoelectric effect, the pressure-sensitive power generation block 1134 converts mechanical energy into electrical energy. The generated electrical energy is transmitted to the energy storage device through the pin 1135 for storage, or directly powers other low-power components of the device, thereby realizing the partial self-powering function of the device.

[0031] S3. Ambient light simulation process According to actual measurement requirements, the operator selects the corresponding ambient light simulation mode through the controller to simulate natural light in different time periods or artificial light in specific places.

[0032] If the selected simulation mode requires the bulb 203 to rotate to simulate a dynamic lighting effect, the controller starts the motor three 208, and the motor three 208 drives the gear four 205 to rotate. The gear four 205 engages with the annular internal gear 202 on the disk 201, driving the annular internal gear 202 to rotate, thereby causing the multiple bulbs 203 installed on the annular internal gear 202 to rotate accordingly, simulating dynamic ambient light effects such as sunlight movement and light rotation.

[0033] The controller accurately adjusts the brightness and color temperature of the bulb 203 by adjusting the circuit according to the selected simulation mode. When simulating the morning sunlight, the brightness of the bulb 203 is gradually increased and the color temperature is set to a warmer tone. When simulating the strong light at noon, the brightness is adjusted to a higher value and the color temperature is set to a cooler tone. By accurately controlling the parameters of the bulb 203, lighting conditions similar to the actual environment are created.

[0034] If it is necessary to measure the illumination under the simulated ambient light from different angles, the controller starts the second motor 206. The second motor 206 drives the disc 201 to rotate, driving the entire angle adjustment mechanism 1 installed on the disc 201 to rotate to a suitable position, providing conditions for illumination measurement at different angles. When the second motor 206 is working, the controller ensures that the third motor 208 stops working to avoid mechanical interference caused by the simultaneous operation of the two motors, thereby ensuring stable operation of the device.

[0035] S4. Data processing and recording The controller receives the measurement data transmitted by the illuminometer 101, performs filtering processing on the data, removes noise interference, improves the accuracy of the data, analyzes the data according to a preset algorithm, and calculates the average illuminance at different angles, illuminance change curves, etc.

[0036] The processed data is stored in the device's built-in memory and can be exported by connecting to external devices. The controller can send the data to the display screen to present it to the operator in an intuitive graphical or numerical form, allowing them to view the measurement results in real time.
