In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples without contradiction.

[0043] The following are two commonly used schemes for testing the uniformity of light sources in the prior art.

[0044] Figure 1 is a flowchart of the conventional test of the uniformity of light sources in the prior art.

[0045] Referring to Figure 1 , Method 1: First, the light spot of the light source to be tested is projected onto a uniform projection plane or receiving screen; second, the light spot image on the projection plane is obtained by a camera or image collector; finally, through software processing, whether the uniformity of the light source to be tested is qualified is determined according to the brightness parameter or the gray scale parameter of the light spot based on the current judgment standard.

[0046] However, this method has the following disadvantages.

[0047] 1. The projection area of this method is a plane, which is relatively accurate for the test of parallel light, but cannot effectively cover all the outgoing light of the light source to be tested for divergent light sources, so that this scheme is relatively limited in the form of testable light sources and has poor accuracy.

[0048] 2. The camera shooting is affected by the test environment and the material of the projection area, resulting in low test accuracy.

[0049] 3, the judgment standard is influenced by the image parameter setting of the shooting camera or the image collector and the difference of the software platform, and errors exist.

[0050] Figure 2 is the effect schematic diagram of the dark angle effect in the prior art; Figure 3 is the effect schematic diagram of the flashlight effect in the prior art.

[0051] Referring to Figure 2 and Figure 3 , method two: first, the to-be-tested light source is placed in a relatively dark environment through a support, then the device is erected to the height of actual application and the object distance to be measured, and then the to-be-tested light source is started; second, the to-be-tested light source is used to illuminate the real scene to which the product is applied, a camera is aligned to the front to shoot, whether the lighting of the center and the periphery of the shot picture is uniform, whether there is a light supplement dark angle (such as Figure 2 ) or whether there is a flashlight effect (such as Figure 3 ) is judged through experience, and then whether the lighting effect conforms to the actual use is determined.

[0052] However, the method has the following disadvantages.

[0053] 1, the method is more dependent on the professional experience of the tester, is also influenced by the shooting site, and for different products, the application situation is changeable, and the judgment basis will also change accordingly, so that the light supplement lighting system cannot be reasonably judged, and there is no white box test method to determine the design standard of the light supplement lighting.

[0054] 2, the judgment standard is influenced by the image parameter setting of the shooting camera or the image collector and the difference of the software platform, and errors exist.

[0055] Figure 4 is a structure schematic diagram of a light source detection device provided by an embodiment of the present application.

[0056] Referring to Figure 4 , the present application provides a light source detection device, which comprises a light source support (not shown in the figure), a light source detection surface 200 and an opaque shell 300, and the light source support is used for fixing a to-be-tested light source 100, wherein the to-be-tested light source 100 can be any existing light source, such as a car lamp, a street lamp or a backlight light source, and various parallel light source products can also be used.

[0057] The light source detection surface 200 is arranged around the outside of the light source support and is arranged at a preset distance from the light source support, which can be adaptively designed according to the volume of the to-be-detected light source 100 and the type of data to be detected; wherein the distance from each point on the light source detection surface 200 to the light source support is equal, and the light source detection surface 200 is used for detecting the light emitted by the to-be-detected light source 100, so as to obtain the illumination data of the to-be-detected light source 100 (the explanation of the illumination data is described below).

[0058] The opaque shell 300 is arranged around the outside of the light source detection surface 200, and the opaque shell 300 is used for filtering external stray light, such as external ambient light or reflected light on external objects; the opaque shell 300 can be made of metal, wood, opaque plastic or opaque rubber; the shape of the opaque shell 300 can be a cube, a sphere or a cylinder, and can be adaptively selected according to actual conditions; in the embodiment of the utility model, the spherical opaque shell 300 is taken as an example.

[0059] Figure 5 is a flowchart of the light source detection method provided by the embodiment of the utility model.

[0060] Referring to Figure 5 , the following shows the use steps of the light source detection device provided by the embodiment of the utility model.

[0061] Step 1: fix the to-be-detected light source 100 on the light source support, and direct the light-emitting side of the to-be-detected light source 100 towards the light source detection surface 200 (if the to-be-detected light source 100 is a divergent light source, this step can be omitted).

[0062] Step 2: turn on the to-be-detected light source 100.

[0063] Step 3: set the sampling time of the light source detection surface 200.

[0064] Step 4: perform data processing on the illumination data obtained by the light source detection surface 200 through the control assembly.

[0066] Referring to Figure 6 to Figure 8 , the control assembly is built-in with a PC processing detector, and the control assembly can fit the illumination data into a light intensity distribution diagram according to the built-in software processing data method or program method; the following shows the processing method of the control assembly on the illumination data (taking the luminous flux as an example).

[0067] Step 1: fitting the collected lighting data into a light intensity distribution map. Figure 7 )

[0068] Step 2: dividing the light intensity distribution map into two parts from the center, optionally one part is analyzed data, and the selected part is divided into n parts. (As shown in Figure 6 8 parts are divided)

[0069] Step 3: calculating the average value t of the luminous flux of each part n (n=1,2,3…n).

[0070] Step 4: subtracting the average value of each equal part from the adjacent value, and then adding the absolute value of the subtraction and taking the average value T.

[0071] Wherein, step 4 can be calculated according to the following formula: .

[0072] Step 5: comparing the average value T with the standard threshold value, when T is greater than the standard threshold value, it is determined that the uniformity of the to-be-tested light source 100 and the lighting data are unqualified; when T is less than or equal to the standard threshold value, it is determined that the uniformity of the to-be-tested light source 100 and the lighting data are qualified.

[0073] In the optional example of the utility model, the annular division method can also be used, as shown in Figure 8 , specifically, it can be adaptively set according to the actual situation.

[0074] Referring to Figure 1 to Figure 8 It can be understood that the light source detection device provided by the utility model embodiment can detect the to-be-tested light source 100 through the light source detection surface 200 arranged around the light source support; wherein, since the distance from each point of the light source detection surface 200 to the light source support is equal, when detecting the to-be-tested light source 100, the distance from each beam of the to-be-tested light source 100 to the light source detection surface 200 is also equal, so that the lighting data obtained through the light source detection surface 200 will not be affected by the type of light source, so that the universality of the light source detection device and the accuracy of the detection result can be guaranteed; in addition, the opaque shell 300 can filter stray light outside the light source detection device, so that the light source detection device can be guaranteed not to be affected by the external environment, thereby reducing the error of the detection result.

[0075] Compared with the prior art, the light source detection device provided by the embodiment of the utility model, compared with the prior method one, because the light source detection surface 200 is arranged around the light source support, and the distance from each point on the light source detection surface 200 to the light source support is equal, therefore, in the process of detecting the to-be-detected light source 100, the light source detection surface can effectively cover the outgoing light of the to-be-detected light source 100 in all directions, so that no matter whether the to-be-detected light source 100 is parallel light or point light source, whether the to-be-detected light source 100 is directive or divergent, the light source detection surface 200 can guarantee the accuracy of the detection result, and the limitation of the testable light source form by the projection area in the prior art can be broken.

[0076] In addition, the light source detection surface 200 directly checks the outgoing light of the to-be-detected light source 100, so that the detection result is not affected by the test environment and the material of the projection area, so that the test precision can be improved; and the detection process does not involve the image acquisition step, so that the test result is not affected by the image parameter setting or software platform difference of the camera or image collector.

[0077] Compared with the prior method two, the lighting data obtained by the light source detection surface 200 is uniformly standardized analyzed and processed by the control assembly, and no human intervention is involved in the detection process of the to-be-detected light source 100 by the light source detection surface 200, so that the test result is not affected by the experience difference of the test personnel, and the judgment basis is not changed due to product difference, based on these improvements, the standardization of the test process and the accuracy and rationality of the detection result can be guaranteed. In addition, the opaque shell 300 can filter the stray light in the external environment, so that the influence of the surrounding environment on the detection process can be avoided.

[0078] Continuing to refer to Figure 4 In the optional embodiment of the utility model, the light source detection surface 200 comprises a support sliding surface 210 and at least one first detection piece 220, the support sliding surface 210 is arranged around the outer side of the light source support, and the distance from each point of the support sliding surface 210 to the light source support is equal.

[0079] The first detection piece 220 is arranged on the support sliding surface 210 and is in sliding cooperation with the support sliding surface 210, the first detection piece 220 can move in any angle or any direction along the support sliding surface 210, in other words, the first detection piece 220 can move to any position on the support sliding surface 210, the first detection piece 220 is used for detecting the outgoing light of the to-be-detected light source 100, and then acquiring the lighting data of the to-be-detected light source 100. The first detection piece 220 can be provided with one or more, in addition, the first detection piece 220 can also select the existing components such as photosensitive sensors, and specifically, adaptive selection can be made according to actual conditions.

[0080] Referring toFigure 4 It can be understood that, in the light source detection device provided by the embodiment of the utility model, the support sliding surface 210 is arranged around the light source support, and the distance from each point on the support sliding surface 210 to the light source support is equal, so that the distance between the first detection piece 220 and the light source support can be ensured to be unchanged no matter where the first detection piece 220 moves to on the support sliding surface 210, and when the light source detection device is used to detect the to-be-detected light source 100, based on such an arrangement, the same detection standard can be provided for the light rays of each angle, so that the accuracy of the detection result is ensured.

[0081] In the optional embodiment of the utility model, the support sliding surface 210 comprises a plurality of warp sliding channels 211 and a plurality of weft sliding channels 212, the warp sliding channels 211 and the weft sliding channels 212 are arranged in a cross manner, the warp sliding channels 211 and the weft sliding channels 212 can be adaptively arranged according to the warp and weft of a spherical surface, and the first detection piece 220 is arranged in at least one of the warp sliding channels 211 and the weft sliding channels 212 and is adapted to slide along the warp sliding channels 211 and the weft sliding channels 212.

[0082] It should be noted that there are various ways of sliding cooperation, such as the cooperation modes of sliding groove and sliding block, magnetic attraction traction sliding or rack and pinion, etc.; in addition, the number of the warp sliding channels 211 and the weft sliding channels 212 can also be adaptively arranged, the warp sliding channels 211 and the weft sliding channels 212 can be arranged on a common spherical surface or can be a cage-shaped frame structure, and specifically, the actual situation can be adaptively selected.

[0083] In the case where the first detection piece 220 is arranged as one, the first detection piece 220 can change the travel route at any adjacent warp-weft intersection point, in other words, the first detection piece 220 can move to any warp sliding channel 211 and weft sliding channel 212 through the warp-weft intersection point; in the case where the first detection piece 220 is arranged as multiple, the first detection piece 220 can be arranged in cooperation with the warp sliding channels 211 and the weft sliding channels 212.

[0084] It should be further noted that the sampling time interval of the first detection piece 220 needs to be much smaller than the moving time interval of the first detection piece 220, so as to ensure the rationality of the detection result, and the specific setting rule can be adaptively arranged according to the actual detection process.

[0085] Reference Figure 4It can be understood that, in the light source detection device provided by the embodiment of the utility model, the warp slide way 211 and the weft slide way 212 are arranged, so that the warp slide way 211 and the weft slide way 212 can be used to restrict the action path of the first detection piece 220 according to actual detection requirements, thereby ensuring the accuracy of the detection result of the first detection piece 220 on the light source 100 to be detected; in addition, the warp slide way 211 and the weft slide way 212 are easy to design and manufacture, so that the manufacturing difficulty of the light source detection device can be effectively reduced.

[0086] Figure 9 It is the distribution schematic view of the first detection piece provided by the embodiment of the utility model.

[0087] Referring to Figure 4 and Figure 9 In the optional embodiment of the utility model, the number of the first detection piece 220 is matched with the sum of the number of the warp slide way 211 and the weft slide way 212, and one first detection piece 220 is arranged on each warp slide way 211 and each weft slide way 212.

[0088] Specifically, in the case of detecting the light source 100 to be detected, the process of each scanning detection can be divided into two steps, first, the first detection piece 220 on all warp slide ways 211 slides along the corresponding warp slide way 211 for scanning, and then the first detection piece 220 on all weft slide ways 212 slides along the corresponding weft slide way 212 for scanning; in the optional example of the utility model, the first detection piece 220 on all weft slide ways 212 can also slide along the corresponding weft slide way 212 for scanning first, and then the first detection piece 220 on all warp slide ways 211 slides along the corresponding warp slide way 211 for scanning.

[0089] Referring to Figure 4 and Figure 9 It can be understood that, in the light source detection device provided by the embodiment of the utility model, the number of the first detection piece 220 is matched with the sum of the number of the warp slide way 211 and the weft slide way 212, so that the detection time of the first detection piece 220 on the light source 100 to be detected can be effectively reduced, the efficiency of the light source detection device can be greatly improved, and the comprehensiveness and accuracy of the test result can be ensured.

[0090] In the optional embodiment of the utility model, unlike the foregoing embodiment, the light source detection device comprises a support rotating surface and at least one second detection piece, the support rotating surface is arranged around the outer side of the light source support, the distance from each point on the support rotating surface to the light source support is equal, and the support rotating surface can rotate around the light source support; the setting mode of rotation is relatively common, and specific reference can be made to the prior art adaptive setting.

[0091] The second detection member is arranged on the support rotating surface, and is similar to the first detection member 220 in the foregoing embodiment, and can also be a photosensitive sensor, and the second detection member is also used for detecting the outgoing light of the to-be-detected light source 100, and further obtains the illumination data of the to-be-detected light source 100. The second detection member can be arranged at the intersection of the meridian and the parallel on the support rotating surface, or can be arranged randomly and uniformly.

[0092] It can be understood that, in the light source member device provided in the embodiment of the utility model, the second detection member arranged on the support rotating surface can rotate together with the support rotating surface during the rotation of the support rotating surface around the light source support, and in the detection process of the to-be-detected light source 100, based on such a configuration, the moving path of the second detection member can cover all the outgoing light of the to-be-detected light source 100, so that the light source detection surface 200 can comprehensively cover the outgoing light of the to-be-detected light source 100, and further, the effectiveness and accuracy of the detection result of the light source detection device can be ensured.

[0093] In the optional embodiment of the utility model, the shape of the light source detection surface 200 comprises one of a spherical shape and a hemispherical shape; in the case that the light source detection surface 200 comprises the support rotating surface and the second detection member, the shape of the light source detection surface 200 can be a spherical surface, or can be a hemispherical surface, and in some optional examples, can also be one fourth or one eighth of a spherical surface, etc.

[0094] In the case that the light source detection surface 200 comprises the support sliding surface 210 and the first detection member 220, the shape of the light source detection surface 200 is also related to the shape of the to-be-detected light source 100, when the light source is divergent, for example, a point light source, in this case, the shape of the light source detection surface 200 can only be a spherical surface; when the light source is directional, for example, parallel light or light with a specific angle, the light source detection surface 200 can be a spherical surface, or can be a hemispherical surface, and in summary, as long as the light source detection surface 200 can comprehensively cover the outgoing light of the to-be-detected light source 100, whether it is a spherical surface or a hemispherical surface, it can be adaptively set according to the actual situation.

[0095] Continuing to refer to Figure 4 In the optional embodiment of the utility model, the light source detection surface 200 is arranged on the inner wall of the opaque shell 300, and the light source detection surface 200 and the opaque shell 300 can be integrally formed, or can be combined in a splicing manner. Similar to the foregoing embodiment, in the case that the to-be-detected light source 100 is directional, the opaque shell 300 comprises a hemispherical shell or a spherical shell; in the case that the to-be-detected light source 100 is divergent, the opaque shell 300 comprises a spherical shell, and when the light source detection surface 200 comprises the support rotating surface, the opaque shell 300 can also be a hemispherical shell.

[0096] It is easy to understand that by setting the light source detection surface 200 together with the opaque shell 300, the assembly design of the light source detection surface 200 can be facilitated, the assembly steps of the light source detection device can be reduced, and the assembly difficulty can be reduced.

[0097] With reference to Figure 4 In optional embodiments of the present application, the light source detection device further comprises a support assembly 400, the support assembly 400 comprises a base 410, a support arm 420 and a cantilever arm 430, the support arm 420 is a bent structure, the first end of the support arm 420 is fixed to the base 410, the second end of the support arm 420 is used to connect the cantilever arm 430, the end of the cantilever arm 430 away from the support arm 420 is used to connect the light source support, and the opaque shell 300 is hung at the second end of the support arm 420. It should be noted that when the light source detection surface 200 is arranged on the inner wall of the opaque shell 300, the length of the cantilever arm 430 needs to be equal to the radius of the opaque shell 300. It can be understood that by arranging the support assembly 400, stable support can be provided for the opaque shell 300, the light source detection surface 200 and the light source support, and the stability of the light source detection device during use can be ensured.

[0098] In optional embodiments of the present application, the lighting data comprises at least one of the luminous flux, the radiation intensity, the illuminance and the gray scale of the to-be-detected light source 100, and correspondingly, the first detection member 220 and the second detection member can also be selected from an illuminance sensor or a gray scale sensor, etc. In optional examples of the present application, the lighting data can also be any combination of the four, so that the light source detection device can meet the detection requirements of more different forms of to-be-detected light sources 100, and the versatility of the light source detection device can be improved.

[0099] Figure 10 is a front view of the opaque shell according to an embodiment of the present application.

[0100] With reference to Figure 4 and Figure 10 In optional embodiments of the present application, the light source detection device further comprises an extinction material layer 500, the extinction material layer 500 is arranged on the inner wall of the opaque shell 300. It can be understood that when the to-be-detected light source 100 is irradiated on the components such as the opaque shell 300, the warp slide 211 or the weft slide 212, reflected light can be generated inside the opaque shell 300. By arranging the extinction material layer 500, the reflected light can be absorbed, so that the influence of the internal reflected light on the detection result can be avoided, and the accuracy of the detection of the light source detection device can be improved.

[0101] Two specific examples of the present application are shown below.

[0102] Example one.

[0103] Randomly select a lighting device for testing, the steps are as follows:

[0104] 1. First, place the device to be tested at the light source support, the diameter of the light source detection surface 200 is 1 m, and the light emitting position of the device to be tested is vertically oriented to the side with the first detection piece 220.

[0105] 2. Turn on the device.

[0106] 3. Set the moving interval of the first detection piece 220 to 50 mm / min, and the sampling interval of the first detection piece 220 to 0.1 s at a time, and then start the device test.

[0107] 4. Use the control component to fit the collected luminous flux or radiant flux data into a light intensity distribution map.

[0108] 5. Divide the light intensity distribution map into left and right parts from the center, select the left part as the analysis data, and divide the selected part into 10 parts according to the latitude, and obtain the average value of the luminous flux or radiant flux of each part, respectively t1, t2, t3, t4…t 10 Then subtract the adjacent values of each equal division average value, add the absolute value of the result of the subtraction, and take the average value T=(|t1-t2|+|t2-t3|+…|t9-t 10 |) / 9=18.74 lm.

[0109] 6. Since the threshold standard obtained after a large number of verifications of the characteristics of this type of lighting product is 20 lm, it can be judged that when T>20 lm, the lighting source uniformity is unqualified, and when T≤20 lm, the lighting source uniformity is qualified. According to the current test T=18.74 lm, which is less than 20 lm, the lighting device light source uniformity meets the standard.

[0110] Example two.

[0111] Randomly select a lighting device for testing, the steps are as follows:

[0112] 1. First, place the device to be tested at the light source support, the diameter of the light source detection surface 200 is 1 m, and the light emitting position of the device to be tested is vertically oriented to the side with the first detection piece 220.

[0113] 2. Turn on the device.

[0114] 3. Set the moving interval of the first detection piece 220 to 50 mm / min, and the sampling interval of the first detection piece 220 to 0.1 s at a time, and then start the device test.

[0115] 4. Use the control component to fit the collected luminous flux or radiant flux data into a light intensity distribution map.

[0116] 5. The spectral intensity distribution is divided into two parts by the center, and the left part is selected as the analysis data, and the selected part is divided into 10 parts according to the latitude, and the average value of the light flux or the radiation flux of each part is obtained, which is t1, t2, t3, t4…t 10 Then, the adjacent values of each equal division average value are subtracted, the absolute value of the subtraction result is added, and the average value T=(|t1-t2|+|t2-t3|+…|t9-t 10 |) / 9=24.39lm.

[0117] 6. Since the threshold standard obtained after a large number of verifications of the characteristics of the lighting product of this type is 20 lm, it can be judged that when T>20 lm, the uniformity of the lighting source is unqualified, and when T≤20 lm, the uniformity of the lighting source is qualified, according to the current test T=24.29 lm, which is greater than 20 lm, so the uniformity of the light source of the lighting device does not meet the standard.
