[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0028] The light intensity detection assembly 10 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.
[0029] Referring to Figure 1 and Figure 2 , the light intensity detection assembly 10 according to the first aspect embodiment of the present utility model includes an optical wire harness 1 and a light intensity detector 2. The optical wire harness 1 has a receiving section 11, a main body section 12, and an output section 13 that are connected in sequence. The surface of the receiving section 11 away from the main body section 12 is a receiving surface 111, and the receiving surface 111 is used to receive ambient light; the surface of the output section 13 away from the main body section 12 is an output surface 131, and the light transmitted to the output section 13 is adapted to emit from the output surface 131; the light intensity detector 2 is used to detect the light intensity at the output surface 131. Wherein, in the direction from the main body section 12 to the receiving section 11, the light passing surface of the receiving section 11 increases, and in the direction from the main body section 12 to the output section 13, the light passing surface of the output section 13 increases.
[0030] When it is necessary to detect the light intensity in a specific direction at a position to be measured, the receiving section 11 of the optical wire harness 1 can be placed at the position to be measured, the receiving surface 111 is oriented towards the direction to be detected, then the main body section 12 is placed in the direction away from the receiving surface 111, and the output section 13 is placed away from the receiving surface 111. After that, the light intensity detector 2 is used to detect the light intensity at the output surface 131 of the output section 13. Wherein, the light intensity X in a specific direction at the position to be measured, the emitted light power P at the output surface 131, and the area S of the output surface 131 satisfy the following condition: X = P / (K * S), where K is the light energy transfer efficiency of the optical wire harness 1.
[0031] By arranging an optical wire bundle 1 at one end of the detection head of the light intensity detector 2 and placing the receiving end of the optical wire bundle 1 at the position to be measured, the light intensity detector 2 can be guided away from the position to be measured to detect the light intensity at the position to be measured, reducing the interference of the light intensity detector 2 on the light at the position to be measured due to the occlusion or reflection of light, making the light intensity at the position to be measured more real, and thus improving the reliability of the measurement result.
[0032] For example, the optical wire bundle 1 can be an optical fiber component, which can make the whole optical wire bundle 1 relatively slender and flexible, facilitating the bending of the optical wire bundle 1, so that the main body section 12 of the optical wire bundle 1 can be easily bent to the side away from the receiving surface 111, reducing the interference of the optical wire bundle 1 on the light at the position to be measured due to the occlusion or reflection of light, making the light intensity at the position to be measured more real, improving the reliability of the light intensity detection component 10, and improving the reliability of the measurement result.
[0033] By making the receiving section 11 of the optical wire bundle 1 larger, the optical wire bundle 1 can receive more light through the larger receiving section 11, so that more light is transmitted to the output section 13 through the main body section 12, reducing the intensity loss during the light transmission process, making the light intensity transmitted to the output section 13 brighter, and facilitating the detection of the light intensity detector 2.
[0034] For example, the optical wire bundle 1 can be an optical fiber component to reduce the loss of light in the optical wire bundle 1, ensure the brightness of the light when it exits the output surface 131, make the light intensity transmitted to the output section 13 brighter, and improve the reliability of the optical wire bundle 1.
[0035] By making the output section 13 of the optical wire bundle 1 larger, the light intensity detector 2 can have a larger inspection range, reducing the detection error caused by small-range detection, ensuring the accuracy of the measurement result of the light intensity detector 2, and improving the overall performance of the light intensity detection component 10.
[0036] According to the light intensity detection component 10 of the present utility model, by arranging an optical wire bundle 1 with thick ends and a thin middle, it is beneficial to the placement of the optical wire bundle 1, the space occupied by the main body section 12 is reduced, the occlusion of the light emitted by the light source to be measured by the optical wire bundle 1 is reduced, and the reliability of the light intensity entering the receiving section is effectively ensured; at the same time, by making the receiving section 11 larger, the optical wire bundle 1 can receive more light through the larger receiving section 11, so that more light is transmitted to the output section 13 through the main body section 12, reducing the intensity loss during the light transmission process; moreover, by making the output section 13 larger, the light intensity detector 2 can have a larger inspection range, reducing the detection error caused by small-range detection, ensuring the accuracy of the measurement result of the light intensity detector 2, and improving the overall performance of the light intensity detection component 10.
[0037] Referring to Figure 2 , according to some embodiments of the present invention, the receiving surface 111 of the receiving section 11 is a flat surface; this can make the light irradiated onto the receiving surface 111 more uniform, thereby better simulating the state of the product being irradiated by light at the position to be measured, ensuring that the light transmitted from the receiving surface 111 to the output surface 131 is closer to the actual value, and improving the reliability of the light intensity detection component 10.
[0038] Optionally, the receiving surface 111 can also be an arc surface protruding away from the main body section 12. This can effectively prevent the light entering the receiving section 11 from the receiving surface 111 from being reflected out of the receiving surface 111, enabling the light entering the receiving section 11 from the receiving surface 111 to be reliably transmitted to the output surface 131, making the total luminous flux of the light emitted from the output surface 131 closer to the total luminous flux of the light entering the receiving surface 111, and improving the reliability of the light intensity detection component 10.
[0039] Optionally, the receiving surface 111 can also be an arc surface recessed towards the main body section 12. This can make the light entering the receiving section 11 from the receiving surface 111 scatter evenly in all directions, making the light emitted from the output surface 131 more uniform and making the measurement result of the light intensity detector 2 more accurate.
[0040] Referring to Figure 2 , according to some embodiments of the present invention, the output surface 131 of the output section 13 is a flat surface. This facilitates accurately calculating the total area of the output surface 131, thereby more accurately calculating the light intensity X of the position to be measured in a specific direction, and improving the accuracy of the light intensity detection component 10.
[0041] Referring to Figure 2 , according to some embodiments of the present invention, according to some embodiments of the present invention, the area of the receiving surface 111 is larger than the area of the output surface 131. This can make the light intensity of the light emitted from the output surface 131 higher, making the light emitted from the output surface 131 brighter, reducing the situation where the light emitted from the output surface 131 is weak due to the weak light intensity at the position to be measured, resulting in the light intensity detector 2 being unable to effectively detect the output light power P of the light emitted from the output surface 131, so that the light intensity detector 2 can more reliably detect the output light power P of the light emitted from the output surface 131, improving the reliability of the light intensity detection component 10 and the accuracy of the light intensity detection component 10.
[0042] Referring to Figure 1 and Figure 2, according to some alternative embodiments of the present utility model, the light intensity detector 2 includes a light sensor and a calculation module. The output section 13 is connected to the light sensor, and the light sensor is communicatively connected to the calculation module. The light sensor is configured to transmit its current information to the calculation module, and the calculation module is configured to calculate the light intensity based on the current change of the light sensor.
[0043] This can enable the light rays emitted from the output surface 131 to directly irradiate the light sensor, reduce the loss of light energy during transmission, and enable the light intensity detector 2 to more reliably calculate the output light power P of the light rays emitted from the output surface 131, thereby more reliably calculating the light intensity X of the position to be measured in a specific direction, improving the reliability of the light intensity detection component 10, and improving the accuracy of the light intensity detection component 10.
[0044] Referring to Figure 1 , an environmental light spot inspection device 100 according to an embodiment of the second aspect of the present utility model includes a calibration box body 30 and a light intensity detection component 10. The calibration box body 30 has a calibration cavity, and a light source position and a spot inspection position are provided in the calibration cavity; for example, a light source to be measured for simulating ambient light can be installed at the light source position.
[0045] The light intensity detection component 10 is the light intensity detection component 10 according to the embodiment of the first aspect of the present utility model. The main body section 12 passes through the calibration box body 30, the receiving section 11 is arranged at the spot inspection position, and the receiving surface 111 of the receiving section 11 faces the light source position. The output section 13 is arranged outside the calibration cavity, and the light intensity detector 2 is arranged outside the calibration cavity.
[0046] When performing a light spot inspection on the light source to be measured, the light source to be measured can be first installed at the light source position of the calibration box body 30, the receiving section 11 is arranged at the position to be measured, the receiving surface 111 of the receiving section 11 faces the light source position, the main body section 12 is passed through the calibration box body 30, the output section 13 is led out of the calibration cavity, and then the detection head of the light intensity detector 2 is aligned with the output surface 131 of the output section 13, and the light source to be measured is lit to complete the detection of the light intensity of the light source to be measured at the preset position.
[0047] For example, the environmental light spot inspection device 100 can also be provided with a clamping device. The light source position is arranged at the top of the calibration cavity, the clamping device is arranged at the bottom of the calibration cavity, and the clamping device is configured to clamp the receiving section 11 to position the receiving surface 111 at the position to be measured, avoiding the influence of the manual operation of the operator on the measurement result of the light intensity at the position to be measured, and improving the reliability of the measurement result.
[0048] For example, there can be multiple optical fiber bundles 1, and the light intensity detector 2 is internally provided with optical sensors corresponding one-to-one to the multiple optical fiber bundles 1. In this way, multiple measurements can be carried out on the position to be measured simultaneously, realizing the mutual verification of the measurement results of multiple measurement times, reducing the number of measurements, improving the measurement efficiency, and improving the overall performance of the environmental light spot inspection device 100.
[0049] For the environmental light spot inspection device 100 according to the present utility model, through the above-mentioned light intensity detection component 10, the interference of the environmental light spot inspection device 100 on the light at the position to be measured can be reduced, so as to accurately detect the light intensity of the light source to be measured, effectively avoid the use of the light source to be measured that does not meet the specifications in the light sensing performance test link of the product, so that the calibration lamp can reliably test the light sensing performance of the product, reliably screen out qualified products, reduce the possibility of unqualified products flowing into the market, ensure the quality of the product, and improve the reliability of the environmental light spot inspection device 100.
[0050] For example, the inner wall of the calibration cavity can be covered with light-absorbing material to reduce the reflection of light by the inner wall of the calibration cavity, so as to more accurately detect the light intensity of the light source to be measured.
[0051] Refer to Figure 1 , according to some embodiments of the present utility model, the calibration box body 30 is provided with an installation opening, and the main body section 12 passes through the installation opening. When installing the light source to be measured, the light source to be measured can be placed at the light source position from the installation opening, which is convenient for realizing the installation and fixation of the light source to be measured. When placing the optical fiber bundle 1, the receiving section 11 can be placed at the position to be measured from the installation opening, so that the main body section 12 passes through the installation opening. There is no need to set an opening for avoiding the optical fiber bundle 1, and the structure is simple and easy to use.
[0052] Refer to Figure 1 , in some embodiments of the present utility model, the environmental light spot inspection device 100 further includes: a box door 31, the box door 31 is openably and closably sealed at the installation opening, and defines an avoidance opening with the calibration box body 30, and the avoidance opening is a part of the installation opening. The optical fiber bundle 1 can pass through the avoidance opening. For example, the box door 31 can be a sliding door and is slidably connected to the calibration box body 30; the box door 31 can also be a rotating door and is rotatably connected to the calibration box body 30.
[0053] By providing an openable and closable box door 31, when installing the light source to be measured and the optical wire harness 1, the box door 31 can be opened, so that a relatively large space is exposed at the placement opening, facilitating the installation and fixation of the light source to be measured and the optical wire harness 1; when using the light intensity detector 2 to detect the light at the position to be measured through the optical wire harness 1, the main body section 12 can be moved to the avoidance opening, and then the box door 31 can be closed, reducing the interference of the ambient light outside the calibration cavity to the position to be measured, ensuring the reliability of the light received by the receiving surface 111, ensuring the accuracy of the measurement result of the light intensity detector 2, and improving the reliability of the ambient light inspection device 100.
[0054] Referring to Figure 1 , in some embodiments of the present invention, the ambient light inspection device 100 further includes: a first flexible blocking member, which is disposed at the avoidance opening, and the first flexible blocking member is connected to the side of the box door 31 facing the avoidance opening, and the first flexible blocking member abuts against the side wall of the avoidance opening facing the box door 31. For example, the first flexible blocking member can be a rubber member, the first flexible blocking member can also be a fabric member, and the first flexible blocking member can also be a sponge member.
[0055] By providing the first flexible blocking member to block the avoidance opening, the possibility of light leakage at the placement opening can be effectively reduced, thereby effectively reducing the interference of the ambient light outside the calibration cavity to the position to be measured, ensuring the reliability of the light intensity at the receiving surface 111, ensuring the accuracy of the measurement result of the light intensity detector 2, and improving the reliability of the ambient light inspection device 100.
[0056] Moreover, the first flexible blocking member is relatively soft. When the side wall of the first flexible blocking member moves towards the placement opening, it can reduce the damage to the optical wire harness 1 caused by the first flexible blocking member, effectively ensuring the safety of the optical wire harness 1, enabling the optical wire harness 1 to reliably transmit the light incident from the receiving surface 111 to the output surface 131, improving the reliability of the light intensity detection component 10, and improving the reliability of the ambient light inspection device 100.
[0057] Referring to Figure 1 , in some embodiments of the present invention, the ambient light inspection device 100 further includes: a second flexible blocking member, which is disposed at the avoidance opening, and the second flexible blocking member is connected to the side wall of the avoidance opening facing the box door 31, the first flexible blocking member abuts against the second flexible blocking member, and the main body section 12 is clamped between the first flexible blocking member and the second flexible blocking member. For example, the second flexible blocking member can be a rubber member, the second flexible blocking member can also be a fabric member, and the second flexible blocking member can also be a sponge member.
[0058] When the side wall of the first flexible baffle moves towards the placement opening, the first flexible baffle and the second flexible baffle can clamp the main body section 12 therebetween, preventing the side wall of the box door 31 or the placement opening from bruising the main body section 12, effectively ensuring the safety of the optical wire harness 1, enabling the optical wire harness 1 to reliably transmit the light incident from the receiving surface 111 to the output surface 131, improving the reliability of the light intensity detection component 10, and improving the reliability of the ambient light spot inspection device 100.
[0059] Meanwhile, since both the first flexible baffle and the second flexible baffle are flexible members with a certain deformation ability, when the first flexible baffle and the second flexible baffle squeeze the main body section 12, they can deform and wrap the main body section 12, effectively blocking the avoidance opening, reducing the light leakage points of the placement opening, thereby further reducing the interference of the ambient light outside the calibration cavity on the position to be measured, ensuring the reliability of the light intensity at the receiving surface 111, ensuring the accuracy of the measurement result of the light intensity detector 2, and improving the reliability of the ambient light spot inspection device 100.
