[0002] As an electronic consumer product, a router is an important part of a commercial network and shows a development trend of being thin, light, and fashionable. Due to factors such as the installation height of a ceiling-mounted router, there are strict requirements for the brightness of the signal indicator lights on it. As a component for conducting the light of the indicator lights outward, the light guide column has corresponding parameter requirements for its light transmittance. Different customers will require different light transmittance test values. Therefore, how to quickly test the light transmittance of the light guide column, reduce the input cost, and be consistent with the customer's test conditions has become a difficult problem in the industry. Traditional light transmittance testing equipment is usually large in volume, inconvenient to operate, and difficult to quickly adapt to the testing requirements of different models of light guide columns. Therefore, developing a simple, fast, and highly accurate router light guide column light transmittance testing device has become an important need in the industry. Summary of the Invention

Detailed implementation mode

[0023] The following further elaborates on the present utility model in conjunction with the attached drawings. For parts where the technical features or connection relationships described in this solution are not detailed, the prior art is adopted. A light guide column light transmittance testing device, as Figures 1 to 3 shown, includes a base 1, on which a light input light source 2, a test component 3 and a light guide column fixing part 4 are provided.

[0024] The light input light source 2 is powered on to emit green light. A brightness regulator 5 is connected between the light input light source 2 and the power supply through a conductive cable. The brightness regulator 5 is an electrical device that changes the luminous flux of the light source in the lighting device and adjusts the illuminance level, realizing that the brightness of the light input light source 2 is adjustable between 0 and 3000 cd / m² to meet the test requirements under different conditions.

[0025] The test component 3 includes a separated test probe 3a and a host of light transmittance meter 3b with a display screen, which are connected by a conductive cable; a highly sensitive sensor is arranged in the test probe 3a, and the light input light source 2 is powered on and irradiates towards the sensor.

[0026] The light guide column fixing part 4 is located between the light input light source 2 and the test probe 3a. The light guide column fixing part 4 includes an upper half fixing part 4a and a lower half fixing part 4b. Each of the upper half fixing part 4a and the lower half fixing part 4b is provided with a concave pit. The two corresponding concave pits can be aligned and combined into a cavity for accommodating the light guide column. There is a transverse through hole in the cavity. The through hole is located between the light input light source 2 and the test probe 3a. The gaps between both the light input light source 2 and the test probe 3a and the edge of the through hole are ≤ 1.5 mm. The small gap reduces external light interference and ensures accurate test results. The cavity is used to place the light guide column. The light input light source 2 is powered on and irradiates through the light guide column in the through hole towards the sensor, and the sensor measures the light intensity passing through the light guide column.

[0027] To achieve rapid clamping and release of the light guide column, ensure the efficiency of the test process, and also ensure the position alignment accuracy between the light guide column and the light source, one side of the upper half fixing member 4a and the lower half fixing member 4b is hinged through a hinge 4c, enabling the upper half fixing member 4a to flip open and close based on the lower half fixing member 4b. The mating surface of the two is a plane. Magnetic attraction materials 4d are provided in the upper half fixing member 4a and the lower half fixing member 4b, and the magnetic attraction materials 4d in the two attract each other to ensure a small seam and a tight mating state after combination. The hinge 4c and the magnetic attraction material 4d are respectively located on both sides of the pit, and the magnetic attraction material 4d is a magnet block embedded in the upper half fixing member 4a and the lower half fixing member 4b.

[0028] To reduce the possible damage to the light guide column during the process of picking up, placing, and clamping, the upper half fixing member 4a and the lower half fixing member 4b are made of phenolic plastic with moderate hardness. If metal materials are used, it is easy to bump or scratch the surface of the light guide column, affecting the product quality; the black upper half fixing member 4a and the lower half fixing member 4b have good light shielding effect after combination to avoid the interference of external light on the test results.

[0029] To optimize the layout design of each component on the base 1 and facilitate the test operation, the base 1 includes a connected platform surface 1a and an inclined surface 1b. The included angle α between the platform surface 1a and the inclined surface 1b ranges from 110° to 160°. The light inlet light source 2, the lower half fixing member 4b, and the test probe 3a are all fixed on the upper surface of the platform surface 1a, and the distance between the light inlet light source 2 and the test probe 3a is adjustable. There is an area for placing the light transmittance meter main unit 3b and the brightness regulator 5 on the inclined surface 1b. Specifically, an upper opening bin 1b-1 is provided on the inclined surface 1b, and the light transmittance meter main unit 3b is placed in the upper opening bin 1b-1 for convenient picking up and placing.

[0030] When the light guide column light transmittance test device of the present utility model is specifically used, first, without placing the product to be tested, check whether the brightness of the light inlet light source 2 meets the specified value (adjust the set value to 1000 ± 50 cd / m² using the brightness regulator 5). After the check, flip open the upper half fixing member 4a from the lower half fixing member 4b, and place the light guide column product in the pit on the lower half fixing member 4b. Specifically, the light inlet surface of the light guide column (i.e., the side close to the lamp bead in the router product) is placed close to the light inlet light source 2. After the product is placed, flip down and close the upper half fixing member 4a. Under the action of gravity and magnetic attraction, the upper half fixing member 4a and the lower half fixing member 4b have a small seam and a good light shielding effect after combination; the light inlet light source 2 is energized to irradiate the sensor in the test probe 3a through the light guide column in the through hole, and the sensor receives the light passing through the light guide column. The data processing unit built in the light transmittance meter main unit 3b analyzes and processes the collected optical signals, calculates the light transmittance, and the value is displayed on the display screen and can be sent to external devices through the data transmission module.

[0031] A light transmittance testing device for the light guide column of a router according to the present utility model can provide a fast, accurate and easy-to-operate light transmittance testing solution for router production. This device can simulate the lighting conditions in actual use, quantitatively evaluate the light transmittance of the light guide column, and ensure that the indicator light source of the router can maintain sufficient brightness and uniformity after passing through the light guide column. This device can adapt to light guide columns of different specifications. When testing light guide columns of different shapes, it is only necessary to replace the light guide column fixing part with a matching concave pit shape, which is easy to operate and the test results are reliable, which is beneficial to improving the overall quality and efficiency of router product manufacturing.

Any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention shall be included within the protection scope of the present utility model.
