[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The brightness of indicator lights on the surfaces of devices, modules, boards, trays, and drive trays must pass verification testing. This is typically done using a colorimeter with the probe touching or covering the indicator lights.

[0034] However, the colorimeter has the following problems in actual use:

[0035] First, it is too large to be carried;

[0036] Second, the operation is cumbersome and requires special personnel to operate;

[0037] Third, when the avoidance space around the indicator light being measured is small, the colorimeter probe covers or contacts the indicator light being measured, resulting in measurement failure.

[0038] Therefore, in order to solve the above problems in turn, a device for testing the brightness of an indicator light is proposed, which is described in detail below:

[0039] First, see Figure 1 and Figure 2 The embodiment of the present application provides an indicator light brightness testing device to solve the problems in the related art of cumbersome operation of the colorimeter and difficulty in covering or contacting the indicator light under test in a small space with the probe.

[0040] An indicator light brightness testing device, comprising:

[0041] A box body 1 having a plurality of light-transmitting holes 2;

[0042] A circuit board 3 is disposed within the box body 1 and is provided with light-emitting elements 4 having the same number as the light-transmitting holes 2, wherein every three light-emitting elements 4 correspond to one indicator light under test, and the brightness thereof corresponds to the upper limit of normal brightness, the lower limit of normal brightness, and the upper limit of cross-talk brightness of the indicator light under test, respectively;

[0043] Multiple light guide columns 5, the number of which is equal to the number of light-transmitting holes 2; one vertical end of the light guide column 5 is connected to the light-transmitting hole 2, and the other vertical end is connected to the light-emitting element 4; the light guide column 5 is located between the light-transmitting hole 2 and the light-emitting element 4 to guide the light from the light-emitting element 4 to the corresponding light-transmitting hole 2.

[0044] Through the above arrangement, every three light-emitting elements 4 correspond to one indicator light to be tested for visual inspection, thereby realizing visual inspection of the indicator lights to be tested; only the indicator lights to be tested that fail the visual inspection need to be accurately measured using a colorimeter, which greatly improves the overall test efficiency of the indicator lights to be tested, and there is no need for professionals to measure all the indicator lights one by one using a colorimeter; secondly, the probe structure is eliminated, and it is only necessary to place the side of the box body 1 with the light-transmitting hole 2 parallel to the position of the indicator light to be tested and place the standard brightness indicator light close to the indicator light to be tested, and it is not necessary to place it at the position of the indicator light to be tested, which changes the test method and facilitates the detection.

[0045] Among them, the reason why parallel spacing is required during testing is that: there is a certain deviation in the light at the side viewing angle. When the side of the box body 1 with the light-transmitting hole 2 is parallel to the position of the indicator light to be tested, the inspector's eyes are facing the plane of the side of the box body 1 with the light-transmitting hole 2 and the position of the indicator light to be tested, ensuring the visual inspection effect; in this way, it is not necessary to put it in the space where the indicator light to be tested is located; for example, if the indicator light to be tested is in a space with a small displacement, its light can pass through the shell of the device. At this time, the inspector only needs to place the box body 1 on the shell for visual inspection. The above indicator light brightness test device detects the brightness of the final effect presented by the indicator light to be tested on the device / module / single disk, which includes but is not limited to the actual brightness of the lamp bead after passing through the influencing factors such as the light guide column, PC mask, and assembly gap, that is, the indicator light, not the lamp bead itself.

[0046] In some preferred embodiments, to solve the problem that the colorimeter is large and inconvenient to carry, the following configuration is provided:

[0047] The box body 1 includes an upper box body 100 and a lower box body 101. The upper box body 100 and the lower box body 101 are connected by a partition 102 to divide the internal space of the box body 1 into a first space and a second space distributed vertically. The upper box body 100 has an upper cover with an opening at the bottom, and the lower box body 101 has a lower cover with an opening at the top. A light-transmitting hole 2 is provided at the top of the upper box body 100. The partition 102 also effectively prevents light from the light-emitting element 4 from escaping downward, thereby providing light shielding.

[0048] A circuit board 3 and a light guide 5 are arranged in the first space;

[0049] A mobile power source 6 connected to the circuit board 3 is provided in the second space.

[0050] The above describes the general structure of the indicator light brightness test device. It is divided into several components that can be assembled. It also includes a mobile power supply 6, which allows it to be used without an external power supply. Its overall size is reduced, and it lacks a probe structure, resulting in a simple overall structure. For example, the indicator light brightness test device can be configured to be 15 cm × 9.2 cm × 3.8 cm in length, width, and height, allowing it to be carried to a workstation, laboratory, computer room, or other R&D / testing / engineering site via transportation such as cars, subways, high-speed trains, and airplanes.

[0051] In addition, it does not require professional training for users. It only requires visual comparison of the normal brightness upper limit, the normal brightness lower limit and the cross-light brightness upper limit. There is no need to adjust the device to adapt to different tested indicator lights. There is no need to find an external socket power supply. It can be used as long as the mobile power supply 6 has power.

[0052] The types of indicator lights that can be tested are based on the type and quantity of the light-emitting elements 4 on the circuit board 3, as well as the settings and changes made by the fixed resistors and variable resistors on the circuit board 3; that is, by adjusting the variable resistor or replacing the fixed resistor to change the brightness value of the light-emitting element 4, the normal brightness upper limit, normal brightness lower limit and crosstalk brightness upper limit corresponding to each indicator light color are solidified in the circuit board 3 as the standard brightness for brightness comparison testing; the tester only needs to carry this device and visually compare it with the indicator light to quickly complete the test, and only the indicator lights that fail the visual test need to be accurately measured using a colorimeter, which greatly improves the overall test efficiency of the indicator lights.

[0053] Furthermore, to avoid unexpected situations, such as when the mobile power supply 6 runs out of power after being used for a long time, the following settings are provided:

[0054] The lower box body 101 is provided with an operation window 103 corresponding to the jack end of the mobile power supply 6;

[0055] The circuit board 3 is provided with a USB power connector 12 ; the upper box body 100 is provided with a slot 104 corresponding to the USB power connector 12 .

[0056] Thus, the USB power connector 12 can be connected to the mobile power supply 6 or an external power supply, thereby ensuring the working time.

[0057] In some preferred embodiments, to introduce the specific structure of the partition 102 connecting the upper box body 100 and the lower box body 101, refer to the following description:

[0058] The partition 102 includes a flat plate portion 10200 , on which a connecting portion 10201 is provided that fits with the inner walls of the upper box body 100 and the lower box body 101 ; the connecting portion 10201 is connected to the upper box body 100 and the lower box body 101 via a detachable connecting piece.

[0059] Wherein, the upper box body 100 and the lower box body 101 are provided with connection holes 105;

[0060] In the thickness direction of the box body 1, two threaded holes 10202 are provided on the connecting portion 10201, and the two threaded holes 10202 are spaced apart along the thickness direction of the box body 1;

[0061] The detachable connection member includes a first connection screw 7, which passes through a connection hole 105 and is connected to a corresponding threaded hole 10202. This facilitates assembly, reduces connection structures, and expands and enriches the functions of the partition 102.

[0062] Furthermore, the connecting portion 10201 is connected to the top surface of the flat plate portion 10200, and includes a baffle parallel to the length direction of the box body 1, and two connecting ears are provided at the bottom of the baffle; two threaded holes 10202 are respectively provided on the baffle and the connecting ears. In such a structure, the baffle achieves the function of strengthening the stability of the overall structure.

[0063] In some preferred embodiments, the connection and installation form of the light guide column 5 is described as follows:

[0064] The partition 102 is provided with a positioning mounting groove 10203, into which a light guide mounting seat 8 is inserted; the top of the light guide mounting seat 8 is provided with a circuit board avoidance groove extending along the length of the box body 1; multiple light guide columns 5 are arranged in two rows, with each row of light guide columns 5 correspondingly mounted on the top of a light guide mounting seat 8. There are two positioning mounting grooves 10203, spaced apart across the width of the box body 1; multiple light transmission holes 2 are provided on the top of the box body 1, in two rows; each row of light transmission holes 2 corresponds to a light guide mounting seat 8, achieving the function of the partition 102 providing a connection position for the light guide columns 5, thereby ensuring the stability of the light guide columns 5 installation position and preventing them from being offset by external vibrations and impacts, resulting in misalignment with the light transmission holes 2.

[0065] Furthermore, in order to enhance the relative stability between the light guide column 5, the light-transmitting hole 2, and the light-emitting element 4, connecting columns 9 are provided on both sides of the circuit board avoidance groove at the top of the light guide mounting seat 8; a connecting groove corresponding to the connecting column 9 is provided at the top of the box body 1; a second connecting screw 10 connected to the connecting column 9 is provided in the connecting groove, and the circuit board 3 is fixedly connected by the third connecting screw and the partition 102, so that the light guide mounting seat 8 is connected to the upper box body 100, the lower box body 101, the partition 102, and the circuit board 3 as a whole to ensure the light guiding effect.

[0066] The light guide column 5 can be a separate structure or a Figure 2 The multiple light guide columns 5 shown in the figure are an integrated structure, the top of which has a plane that fits with the inner top of the upper box 100. The top of the structure is for the second connecting screw 10 to pass through, which also enhances the structural strength and prevents light from crossing between each light guide column 5.

[0067] In some preferred embodiments, a PC mask 11 is provided on the top of the box body 1. The PC mask 11 has a through hole corresponding to the light-transmitting hole 2. Text may be printed on the PC mask 11 to identify the type of indicator light being tested. Alternatively, the PC mask 11 may be provided elsewhere on the outer surface of the box body 1.

[0068] This indicator light brightness test device can complete the visual comparison link in the indicator light brightness test at low cost, quickly and efficiently, eliminating the need for professionals to measure all indicator lights one by one using a colorimeter. It also fills the gap that the colorimeter cannot measure when the test space is limited, and is easy to carry to various engineering sites and other environments.
