These lighting products include high and low beam headlights, daytime running lights, turn signals, fog lights, reversing lights, and more. Current interference resistance tests for lighting products rely on observing changes in light using cameras or the naked eye. These observations are susceptible to subjective human judgment errors, are difficult to quantify, and lack standardized criteria. This results in significant inconvenience for users and consumers during operation and testing. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a monitoring device for changes in light intensity that is simple in structure, easy to operate, and convenient and quick to use.

[0004] To address the aforementioned technical problems, the present invention provides a monitoring device for changes in light intensity, comprising a detector body, a power socket connected to the input end of the detector body for supplying power to the detector body, a plurality of glass fiber coaxial cables connected to the detector body, and a monitored lighting product connected between the other ends of two adjacent glass fiber coaxial cables; the detector body includes a metal shielding shell, a plurality of small detection circuit boards welded and fixed inside the metal shielding shell, a plurality of rotary buttons and an LED display screen located on the front of the metal shielding shell, a plurality of channel interfaces for connecting the glass fiber coaxial cables located on the back of the metal shielding shell, and a power input interface; a main control circuit board located inside the metal shielding shell for controlling the monitoring function, a plurality of power lines connected between the small detection circuit boards and the main control circuit board; and a plurality of inductors welded to the main control circuit board.

[0005] Further specifying, the main control circuit board is equipped with a monitoring circuit module for controlling the light intensity when detecting the lighting product. The monitoring circuit module includes the lighting product directly connected to the channel interface, a voltage display module and a photoresistor connected in parallel to the lighting product, and a 10 kΩ resistor connected to the output terminals of the voltage display module and the photoresistor. The lighting module, the resistor, the voltage display module and the photoresistor are all connected in series, while the voltage display module and the photoresistor are connected in parallel.

[0006] Further defined, the metal shielding shell includes a metal base shell placed directly on the ground, and a base shell cover mounted on the metal base shell.

[0007] Further specifying, the main body of the detector is an EMTEK light intensity meter.

[0008] The beneficial technical effects of this utility model are as follows: The monitoring device of this utility model consists of a detector body, a lighting product, and a glass optical fiber coaxial cable. The detector body and the lighting product are connected together via the glass optical fiber coaxial cable to form a current loop. During use, when the light intensity of the monitored lighting product is relatively strong, the resistance used in the lighting product is relatively small, and the current passing through it is relatively large. Therefore, the voltage display module on the detector body displays a relatively large voltage, and the resistance display shows a relatively large resistance value.

[0009] Conversely, when the light intensity of the monitored lighting product is relatively weak, the resistor used in the lighting product is relatively large, and the current passing through it is relatively small. As a result, the voltage display module on the main body of the detector will display a relatively small voltage, and the resistance display will show a relatively small resistance value.

[0010] In this process, by changing the intensity or weakness of the light intensity of the monitored lamp product, the voltage and resistance values ​​displayed on the main body of the detector are changed, thereby achieving the purpose of monitoring the light intensity of the lamp product. Compared with similar products in the prior art, the monitoring device of this utility model has the functions of simple structure, simple operation, and convenient speed.

The specific embodiments described herein are only used to explain and illustrate the understanding of the technical solution of this utility model.

[0018] Please refer to Figures 1 to 5 As shown in the figure, the following describes a monitoring device for changes in light intensity, which includes a detector body 1, a power socket, a plurality of glass optical fiber coaxial cables 2, and a lighting product 3.

[0019] The main body 1 of the detector includes a metal shielding shell, a plurality of small detection circuit boards 5 welded and fixed inside the metal shielding shell, a plurality of rotary buttons 13 and an LED display screen 4 located on the front of the metal shielding shell, a plurality of channel interfaces 6 for connecting glass fiber coaxial cables 2 located on the back of the metal shielding shell, a power input interface 7; a main control circuit board 8 located inside the metal shielding shell for control and monitoring, a plurality of power lines 9 connected between the small detection circuit boards 5 and the main control circuit board 8; and a plurality of inductors 10 welded to the main control circuit board 8.

[0020] The main control circuit board 8 is equipped with a monitoring circuit module for controlling the light intensity when detecting lighting products. The monitoring circuit module includes a lighting product directly connected to the channel interface, a voltage display module and a photoresistor connected in parallel to the lighting product, and a 10 kΩ resistor connected to the output terminals of the voltage display module and the photoresistor. The lighting module, the resistor, the voltage display module and the photoresistor are all connected in series, while the voltage display module and the photoresistor are connected in parallel.

[0021] The metal shielding housing includes a metal base 11 placed directly on the ground and a base cover 12 mounted on the metal base 11. The detector body 1 is an EMTEK light intensity meter. During connection, the power socket is plugged into an external power source and is electrically connected to the detector body 1. The monitored lighting product 3 is connected together via two glass fiber coaxial cables 2. One end of the two glass fiber coaxial cables 2 is connected to the detector body 1, and the other end is connected to the monitored lighting product 3. The power socket provides power to the detector body 1. The detector body 1 and the lighting product 3 are connected together via the glass fiber coaxial cables 2, forming a current loop.

[0022] When in use, when the light intensity of the monitored lamp product 3 is relatively strong, the resistor used on the lamp product 3 is relatively small and the current passing through it is relatively large. In this case, the voltage display module on the main body 1 of the detector will display a relatively large voltage and a relatively large resistance value.

[0023] Conversely, when the light intensity of the monitored lamp product 3 is relatively weak, the resistor used on the lamp product 3 is relatively large, and the current passing through it is relatively small. As a result, the voltage display module on the main body 1 of the detector displays a relatively small voltage, and the resistance display shows a relatively small resistance value.

[0024] In this process, by changing the intensity or weakness of the light intensity of the monitored lamp product 3, the voltage and resistance values ​​displayed on the main body 1 of the detector are changed, thereby achieving the purpose of monitoring the light intensity of the lamp product 3. Compared with similar products in the prior art, the monitoring device of this utility model has the functions of simple structure, simple operation, and convenient speed.

[0025] The preferred embodiments of this utility model have been described above with reference to the accompanying drawings, but this does not limit the scope of the technical solution of this utility model. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope of protection and substantive rights of this utility model shall be within the scope of the technical solution of this utility model.
