Technical Field

[0001] The present application relates to the technical field of light source measurement, and in particular to a distribution photometer light intensity testing method and system. Background Art

[0002] At present, goniophotometers are mainly used to measure the photometric performance of lamps and light sources, that is, the distribution of the luminous intensity and colorimetric values ​​of the laser source of lamps in different directions in space. With the increasing development of modern social science, light sources are diverse, so it is very important to use goniophotometers to test the light intensity of light sources.

[0003] The existing distribution photometer light intensity test method refers to that the light emitted by the light source is collected and focused onto the detector through the optical system. The detector converts the received light energy into an electrical signal and outputs a voltage or current proportional to the light intensity. The voltage data or current data is processed by a computer to generate a light intensity distribution diagram, which displays the light intensity in different directions, and then evaluates the optical properties of the light source such as the brightness distribution. However, the existing distribution photometer light intensity test method does not take into account the influence of the environment on the loss during the light intensity detection process and the influence of the equipment operation on the error during the light intensity detection. The accuracy of the distribution photometer light intensity detection is low and there is room for improvement. Summary of the invention

[0070] The present application is further described in detail below in conjunction with the accompanying drawings.

[0071] The embodiment of the present application discloses a method for testing light intensity using a distribution photometer.

[0072] A method for testing light intensity with a distribution photometer comprises the following steps:

[0073] Reference Figure 1 , step S1, establishing a three-dimensional rectangular coordinate system based on the distribution photometer, and creating a digital twin model of the light source to be measured based on the three-dimensional rectangular coordinate system. Step S1 specifically includes the following sub-steps:

[0076] Step S13: creating a light source digital twin model of the light source to be tested based on a three-dimensional rectangular coordinate system.

[0077] Reference Figure 1 Step S2, dividing the area around the light source to be measured according to the light source parameter information of the light source to be measured to obtain a region division result. Step S2 specifically includes the following sub-steps:

[0078] Step S21, obtaining light source parameter information of the light source to be tested, where the light source parameter information includes light source type information and light source application scenario information.

[0079] Step S22, determining the beam angle of the light source to be measured based on the light source type information of the light source to be measured to obtain light source beam angle information.

[0080] Step S23, based on the light source beam angle information, determine the influence of the beam angle of the light source to be measured on the surrounding area division of the light source to be measured during light source detection to obtain the beam angle division ratio coefficient AG, wherein the narrower the beam angle of the light source to be measured, the smaller the beam angle division ratio coefficient AG.

[0081] Let's take an example to illustrate: LED light sources have narrower beam angles, their light is more concentrated, and the divergence is lower. Fluorescent lamps have relatively wide beam angles, and the light distribution is more uniform. The beam angle of halogen tungsten lamps is between LED light sources and fluorescent lamps, and has a certain degree of divergence, but not as wide as fluorescent lamps. Light sources with more concentrated light should be divided more densely to facilitate staff to better analyze the optical performance of the light source.

[0085] Step S27, performing region division around the light source to be measured according to the region division ratio coefficient S to obtain a region division result, wherein the smaller the region division ratio coefficient S is, the smaller the angle division around the light source in the region division result is.

[0086] Reference Figure 1 , step S3, using a distribution photometer to detect the light intensity of each area around the light source to be measured in the area division result to obtain the actual light intensity value of each area. Step S3 specifically includes the following sub-steps:

[0087] Step S31, based on the area division result, the optical system in the distribution photometer collects the light from each area of ​​the area division result and focuses it onto the detector.

[0088] In step S32, the detector converts the collected light energy into electrical energy and outputs a current proportional to the light intensity, namely, the light intensity current value.

[0089] Step S33, analyzing the light intensity of each area around the light source to be measured based on the light intensity current value to obtain the actual light intensity value of each area.

[0090] Reference Figure 1 , step S4, based on the area division result, when performing light intensity detection in each area, simultaneously detect the environmental parameter information of each area, and analyze the light intensity loss caused by the environment during light intensity detection according to the environmental parameter information to obtain the light intensity loss amount of each area. Step S4 specifically includes the following sub-steps:

[0091] Step S41, based on the area division result, when the distribution photometer performs light intensity test on each area, the environmental parameter information of each area is detected at the same time, the environmental parameter information includes environmental temperature information, environmental humidity information and air medium information, the air medium information includes air influence factor information and air fluidity information, the air influence factor information includes air influence factor type information and air influence factor concentration information of each type of air influence factor.

[0092] In practical applications, changes in air humidity and temperature will affect the refractive index of the air, and thus affect the propagation path and speed of light.

[0093] Step S42, compare the ambient temperature information with the preset ambient temperature threshold to obtain the ambient temperature influence coefficient BW. If the ambient temperature information is consistent with the preset ambient temperature threshold, the ambient temperature influence coefficient BW is 0. If the ambient temperature information is inconsistent with the preset ambient temperature threshold, the difference between the ambient temperature information and the preset ambient temperature threshold is calculated to obtain the ambient temperature difference. The ambient temperature influence coefficient BW is obtained based on the ambient temperature difference. The larger the ambient temperature difference, the larger the ambient temperature influence coefficient BW.

[0094] Step S43, compare the ambient humidity information with the preset ambient humidity threshold to obtain the ambient humidity influence coefficient BS. If the ambient humidity information is consistent with the preset ambient humidity threshold, the ambient humidity influence coefficient BS is 0. If the ambient humidity information is inconsistent with the preset ambient humidity threshold, the difference between the ambient humidity information and the preset ambient humidity threshold is calculated to obtain the ambient humidity difference.

[0098] In actual applications, dust, particles and other impurities in the air will scatter and absorb light, causing the intensity of light to weaken during propagation. This scattering and absorption will make the measured light intensity value lower than the actual value, thus affecting the accuracy of light intensity detection.

[0099] Step S47, obtaining an air flow influence coefficient BD according to the air flow information, wherein the better the air flow information is, the greater the air flow influence coefficient BD is.

[0100] In practical applications, air flow can cause the propagation path of light in space to change, making it impossible for the light to reach the detector stably.

The larger the light intensity loss influence coefficient BTH is, the greater the light intensity loss amount is.

[0103] In a specific application, by analyzing the influence of the ambient temperature and ambient humidity of each area on the light intensity detection of each area of ​​the light source to be measured during the light intensity detection, the ambient temperature influence coefficient BW and the ambient humidity influence coefficient BS are obtained respectively. The ambient temperature influence coefficient BM is obtained according to the ambient temperature influence coefficient BW and the ambient humidity influence coefficient BS, thereby improving the detection accuracy of the ambient temperature and humidity influence coefficient BM. The type and concentration of the influencing factors in the air medium are analyzed to influence the loss of the light intensity detection of each area of ​​the light source to be measured, and the air influence factor type influence coefficient BL and the air influence factor concentration influence coefficient BQ are obtained respectively. The air flow influence coefficient BD is obtained according to the air flow information of the air medium. The air medium influence coefficient BN is obtained according to the air influence factor type influence coefficient BL, the air influence factor concentration influence coefficient BQ and the air flow influence coefficient BD, thereby improving the detection accuracy of the air medium influence coefficient BN. The light intensity loss influence coefficient BTH is obtained according to the ambient temperature and humidity influence coefficient BM and the air medium influence coefficient BN. Then, the light intensity loss amount of each area of ​​the light source to be measured is obtained according to the light intensity loss influence coefficient BTH, thereby improving the detection accuracy of the light intensity loss amount of each area, thereby improving the accuracy of the light intensity detection of the distribution photometer.
