Description

Technical Field

[0001] The present invention relates to the field of layered products, in particular to composite panels. Background Art

[0002] Most existing lamp illumination test boards are single-layer flat plates with the measurement pattern printed on one surface. The following problems exist: The measurement pattern is printed and easily worn; The entire test board is made of light-absorbing materials, which is relatively expensive; The geometric center of the light-emitting surface of the desk lamp needs to be determined manually, which is prone to errors and leads to inaccurate test data. Summary of the invention

[0003] The object of the present invention is to provide a composite test board for testing the illumination of a desk lamp, so as to solve at least one of the above-mentioned technical problems.

[0004] A composite test board for testing illumination of a desk lamp, comprising a plate-shaped body, characterized in that the front side of the plate-shaped body is covered with a first light-absorbing material layer, and the back side of the plate-shaped body is covered with a second light-absorbing material layer; The front of the plate-like body is provided with a first pattern for measuring the illumination of a rectangular area, the first pattern includes a first rectangular frame in the shape of a rounded rectangle, a second rectangular frame in the shape of a rounded rectangle, the second rectangular frame is located in the first rectangular frame, the first pattern also includes four horizontal lines arranged at equal intervals in the horizontal direction, and six longitudinal lines arranged at equal intervals in the longitudinal direction, after the horizontal lines and the longitudinal lines are interlaced, 24 intersecting points arranged in a 100mm*100mm matrix are formed in the first rectangular frame, the two ends of the horizontal lines and the longitudinal lines are connected to the first rectangular frame, 20 intersecting points are formed on the first rectangular frame, and the first pattern is provided with a first circular ring with the intersecting point as the center at the intersecting point; A second pattern for measuring illumination in a sector-shaped area is provided on the back of the plate-shaped body, the second pattern comprising five first line segments, the upper ends of the first line segments intersect to form an intersection point, the first line segments are arranged at equal intervals with the intersection point as the center and 500 mm as the radius to form four sectors with a central angle of 30°, six second circular rings are provided at equal intervals on the first line segments, the distance between two adjacent second circular rings is 100 mm, and the second circular ring located at the intersection point is used as the central ring; The plate-like body is provided with a first opening at the center ring for fixing the laser positioning pen, and the first opening is located at the center of the horizontal line located above the first pattern; The first light absorbing material layer and the second light absorbing material layer are both black, the first pattern is white and protrudes on the plate-like body, the height of the first pattern is equal to the height of the first light absorbing material layer, the second pattern is white and protrudes on the plate-like body, the height of the center ring is greater than the height of the remaining part of the second pattern, and the height of the remaining part of the second pattern is equal to the height of the second light absorbing material layer.

[0005] Beneficial effects: 1. The pattern of the present invention is directly raised on the plate-like body, and has higher wear resistance than the printed pattern in the background technology. 2. The composite test board of the present invention is a three-layer structure, which allows the light-absorbing material layer located on the outside to use light-absorbing materials and the plate-like body located on the inside to use non-light-absorbing materials. Compared with the single-layer all-light-absorbing material structure in the background technology, it has lower cost. 3. The present invention can use the first opening to fix the laser positioning pen, and use the laser positioning pen to assist in judging the geometric center of the light-emitting surface of the desk lamp, which is more accurate than the method of manual naked eye judgment. 4. The present invention increases the height of the center ring, and the center ring with a larger height can be used to fix the laser positioning pen more stably. 5. The present invention is provided with a first pattern for rectangular area illuminance measurement on the front of the plate-like body, and a second pattern for fan-shaped area illuminance measurement on the back of the plate-like body. Compared with the prior art setting of printing patterns only on one side of the board, the size and number of test boards can be effectively reduced, and the measurement of illumination of two areas can be completed by one test board. 6. In the present invention, the positions of the first pattern and the second pattern are limited by the first opening, so that while the laser positioning pen searches for the geometric center, the position of the measuring plate is adjusted to the standard measuring position.

[0006] Preferably, the height of the light-absorbing material located in the first circular ring, the second circular ring, and the center ring is smaller than the height of the ring in which it is located. Thus, an inner concave structure is formed at the circular ring, which can be used to fix an illuminometer or a laser positioning pen. The first circular ring on the second rectangular frame and the first circular ring located in the second rectangular frame are both double circular rings, and the remaining first circular rings are single circular rings. The three second circular rings on the first line segment that are closer to the center ring are double circular rings, and the remaining two second circular rings are single circular rings, and the center ring is a double circular ring. The single circular ring is only one circular ring, and the double circular ring is composed of a small circular ring and a large circular ring sleeved outside the small circular ring. The radius of the small circular ring is smaller than the radius of the large circular ring, and the height of the small circular ring is smaller than the height of the large circular ring. The height of the light-absorbing material located in the first circular ring, the second circular ring, and the center ring is smaller than the height of the small circular ring. Thus, the structure of the double circular ring is used to fix laser positioning pens or illuminometers with different outer diameters. It is also possible that no light-absorbing material layer is provided in the first circular ring, the second circular ring, and the center ring. The inner diameter and outer diameter of the small circular ring are the same at all places. The outer diameter of the large circular ring is the same at all places, and the inner diameter becomes smaller as it approaches the plate-like body, thereby forming a trumpet-shaped structure to facilitate fixing the probe of the illuminometer.

[0007] Preferably, the portion of the longitudinal line located in the second rectangular frame is a white dotted line, the remaining transverse lines and the remaining longitudinal lines are solid lines, the second rectangular frame is a white dotted line, and the first rectangular frame is a white solid line. Thus, the dotted lines are used to ensure that the light absorbing material layer on the measurement plate can flow well, thereby making the light absorbing material layer more evenly covered.

[0008] Preferably, the second pattern further includes five arc lines, which respectively pass through the second circular rings at equal distances from the circular center ring, wherein the three arc lines closest to the circular center ring, the second closest to the circular center ring, and the fourth closest to the circular center ring are white dotted lines, and the two arc lines closest to the third closest to the circular center ring and the fifth closest to the circular center ring are white solid lines. Thus, the dotted lines are used to ensure that the light absorbing material layer on the measuring plate can flow well, thereby making the coverage of the light absorbing material layer more uniform.

[0009] Preferably, the first pattern further includes a third circular ring, the third circular ring is located above the first rectangular frame, and the distance from the third circular ring to the nearest first circular ring is 100 mm. The third circular ring is a single circular ring, and the wall thickness of the third circular ring is equal to the inner diameter difference between the large circular ring and the small circular ring. The third circular ring is used to solve the problem that the center of the light outlet cannot be matched.

[0010] Preferably, the middle one of the five first line segments is provided with an upward extension line, and the second pattern also includes a horizontal line perpendicular to the extension line, the horizontal line passes through the hole center of the center ring, and the height of the extension line and the horizontal line is equal to the maximum height of the center ring. It has the following advantages: 1. The extension line and the horizontal line can be used to place the test board more stably. 2. The shadows of the extension line and the horizontal line can be used to judge the verticality of the test board and the desk lamp, so as to adjust the position of the test board to the best, thereby improving the accuracy of the test data. 3. The horizontal line has a shielding effect, which can effectively prevent the non-test area from interfering with the light of the fan-shaped test area.

[0011] The first light-absorbing material layer and the second light-absorbing material layer are preferably prepared by self-leveling of black dye, and the black dye is preferably a pigment containing black titanium dioxide. The present invention selects the material of the light-absorbing material layer, which can effectively reduce reflection. The present invention also selects the preparation method, and the self-leveling method can effectively solve the problem of uneven surface of the light-absorbing material caused by uneven surface of the plate body or surface defects. Moreover, in the process of self-leveling, under the influence of the surface tension of the dye, a smooth structure will be formed at the junction with the ring and slightly higher than the ring, thereby reducing the reflection at the ring. The plate-like body is preferably formed by injection molding, and the injection molding material for injection molding preferably contains iron powder. Beneficial effects: 1. Iron powder will increase the roughness of the surface of the plate-like body, thereby increasing the contact area between the plate-like body and the dye, and then improving the adhesion effect of the dye. 2. Iron powder can be adsorbed with a magnet, thereby allowing a magnet to be installed on the probe of the illuminance meter and the laser positioning pen to improve the stability of the fixation of the probe of the illuminance meter and the laser positioning pen on the plate-like body.

[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0014] Reference Figure 1 , Figure 2 A composite test board for testing the illumination of a desk lamp comprises a plate-shaped body, a first light-absorbing material layer, and a second light-absorbing material layer.

[0015] About the plate-like body: a first pattern for measuring the illumination of a rectangular area is provided on the front side of the plate-like body, the first pattern includes a first rectangular frame in the shape of a rounded rectangle, a second rectangular frame in the shape of a rounded rectangle, the second rectangular frame is located in the first rectangular frame, the first pattern also includes four transverse lines arranged at equal intervals in the horizontal direction, and six longitudinal lines arranged at equal intervals in the longitudinal direction. After the transverse lines and the longitudinal lines are interlaced, 24 intersection points arranged in a 100mm*100mm matrix are formed in the first rectangular frame, the two ends of the transverse lines and the longitudinal lines are connected to the first rectangular frame, and 20 intersection points are formed on the first rectangular frame. The first pattern is provided with a first circular ring with the intersection point as the center at the intersection point.

[0016] A second pattern for measuring illumination in a sector-shaped area is provided on the back of the plate-shaped body. The second pattern includes five first line segments. The upper ends of the first line segments intersect to form an intersection point. The first line segments are arranged at equal intervals with the intersection point as the center and 500 mm as the radius to form four sectors with a central angle of 30°. Six second circular rings are provided at equal intervals on the first line segments. The distance between two adjacent second circular rings is 100 mm, and the second circular ring located at the intersection point is used as the central ring. The plate-like body is provided with a first opening A at the center ring for fixing the laser positioning pen, and the first opening A is located at the center of the upper horizontal line of the first pattern.

[0017] Regarding the first light absorbing material layer and the second light absorbing material layer, the front side of the plate-like body is covered with the first light absorbing material layer, and the back side of the plate-like body is covered with the second light absorbing material layer, and both the first light absorbing material layer and the second light absorbing material layer are black. The first pattern is white and protrudes on the plate-like body, and the height of the first pattern is equal to the height of the first light absorbing material layer. The second pattern is white and protrudes on the plate-like body, and the height of the center ring is greater than the height of the remaining part of the second pattern, and the height of the remaining part of the second pattern is equal to the height of the second light absorbing material layer.

[0018] The height of the light-absorbing material located in the first circular ring, the second circular ring, and the center ring is smaller than the height of the ring in which it is located. Thus, an inner concave structure is formed at the circular ring, which can be used to fix an illuminometer or a laser positioning pen. The first circular ring on the second rectangular frame and the first circular ring located in the second rectangular frame are both double circular rings, and the remaining first circular rings are single circular rings. The three second circular rings closer to the center ring on the first line segment are double circular rings, the remaining two second circular rings are single circular rings, and the center ring is a double circular ring.

The radius of the small circular ring is smaller than the radius of the large circular ring, and the height of the small circular ring is smaller than the height of the large circular ring. The height of the light-absorbing material located in the first circular ring, the second circular ring, and the center ring is smaller than the height of the small circular ring. Thus, the structure of the double circular ring is used to fix laser positioning pens or illuminometers with different outer diameters. It is also possible that no light-absorbing material layer is provided in the first circular ring, the second circular ring, and the center ring. The inner diameter and outer diameter of the small circular ring are the same everywhere. The outer diameter of the large circular ring is the same at all places, and the inner diameter becomes smaller as it approaches the plate-like body, thereby forming a trumpet-shaped structure to facilitate fixing the probe of the illuminometer.

[0019] Preferably, the portion of the longitudinal line within the second rectangular frame is a white dotted line, the remaining transverse lines and the remaining longitudinal lines are solid lines, the second rectangular frame is a white dotted line, and the first rectangular frame is a white solid line. Thus, the dotted lines are used to ensure that the light absorbing material layer on the measurement plate can flow well, thereby making the coverage of the light absorbing material layer more uniform.

[0020] Preferably, the second pattern further includes five arc lines, which respectively pass through the second circular rings at equal distances from the circular center ring, wherein the three arc lines closest to the circular center ring, the second closest to the circular center ring, and the fourth closest to the circular center ring are white dotted lines, and the two arc lines closest to the third closest to the circular center ring and the fifth closest to the circular center ring are white solid lines. Thus, the dotted lines are used to ensure that the light absorbing material layer on the measuring plate can flow well, thereby making the coverage of the light absorbing material layer more uniform.

[0021] Preferably, the first pattern further includes a third circular ring, which is located above the first rectangular frame, and the distance from the third circular ring to the nearest first circular ring is 100 mm. The third circular ring is a single circular ring, and the wall thickness of the third circular ring is equal to the inner diameter difference between the large circular ring and the small circular ring. The third circular ring is used to solve the problem that the center of the light outlet cannot be matched.

[0022] Preferably, the middle one of the five first line segments is provided with an upward extension line, and the second pattern also includes a horizontal line perpendicular to the extension line, the horizontal line passes through the center of the hole of the center ring, and the heights of the extension line and the horizontal line are equal to the maximum height of the center ring. It has the following advantages: 1. The extension line and the horizontal line can be used to place the test board more stably. 2. The shadows of the extension line and the horizontal line can be used to determine the verticality of the test board and the desk lamp, so as to adjust the position of the test board to the best, thereby improving the accuracy of the test data. 3. The horizontal line has a shielding effect, which can effectively prevent the non-test area from interfering with the light of the fan-shaped test area.

[0023] The first light-absorbing material layer and the second light-absorbing material layer are preferably prepared by self-leveling of black dye, and the black dye is preferably a pigment containing black titanium dioxide. The present invention selects the material of the light-absorbing material layer, which can effectively reduce reflection. The present invention also selects the preparation method, and the self-leveling method can effectively solve the problem of uneven surface of the light-absorbing material caused by uneven surface of the plate body or surface defects. Moreover, in the process of self-leveling, under the influence of the surface tension of the dye, a smooth structure will be formed at the junction with the ring and slightly higher than the ring, thereby reducing the reflection at the ring.

Iron powder can be adsorbed with a magnet, thereby allowing a magnet to be installed on the probe of the illuminance meter and the laser positioning pen to improve the stability of the fixation of the probe of the illuminance meter and the laser positioning pen on the plate body.

[0024] The beneficial effects of a composite test board for testing the illumination of a desk lamp are as follows: 1. The pattern of the present invention is directly raised on the plate-like body, and has higher wear resistance than the printed pattern in the background technology. 2. The composite test board of the present invention is a three-layer structure, which allows the light-absorbing material layer located on the outside to adopt light-absorbing materials and the plate-like body located on the inside to adopt non-light-absorbing materials.
