[0032] In the prior art, a light intensity detector at a fixed position is generally used to simply detect the light intensity of the lamp, which is relatively simple and not comprehensive enough. The prior art lacks a device for detecting the light intensity of the lamp at all angles and at different angles.

[0033] The following is a first embodiment of a fixture device for lamp testing provided by the present invention that can solve the above technical problems.

[0034] Please refer to Figure 1 ,in Figure 1 It is a schematic structural diagram of a first embodiment of a clamping device for testing a lamp of the present invention.

[0035] In the figures, structurally similar elements are denoted by the same reference numerals.

[0036] This embodiment provides a clamping device for lamp testing, which is used to clamp the lamp and is placed in a darkroom. Light intensity detectors are arranged at different positions in the darkroom, and the multiple light intensity detectors are used to detect the light intensity of the lamp at various angles.

[0037] The fixture for lamp testing includes: a base 11, a rotating base 12, and a clamping frame 13. The rotating base 12 is rotatably arranged on the base 11 around a first rotating axis, and the clamping frame 13 is rotatably arranged on the rotating base 12 around a second rotating axis. The first rotating axis and the second rotating axis are skew intersecting. Through the rotational cooperation between the rotating base 12 and the clamping frame 13, the lamp clamped on the clamping frame 13 can be changed to multiple different angles, and light intensity detection in multiple different directions can be performed.

[0038] A plurality of clamping members 14 for clamping lamps are slidably disposed on the clamping frame 13 , and the clamping members 14 are connected to the clamping frame 13 via elastic members, which are used to drive the plurality of clamping members 14 to slide toward the center of the clamping frame 13 .

[0039] It should be noted that the rotation of the rotating seat 12 and the clamping frame 13 is preferably driven by a driving mechanism such as a motor.

[0040] Please refer to Figure 2 In this embodiment, the clamping member 14 includes a bottom block and a clamping block 142. The bottom block is slidably connected to the clamping frame 13. A first screw member 146 is threadedly connected to the bottom block. The operating head of the first screw member 146 is located outside the bottom block. The first screw member 146 is used to fix the bottom block on the clamping frame 13. The clamping block 142 is arranged on a side of the bottom block away from the clamping frame 13.

[0041] Please refer to Figure 3 Optionally, the two sides of the clamping block 142 may be clamping surfaces of different shapes, and the clamping block 142 is rotatably connected to the bottom block. The clamping block 142 switches different clamping surfaces to contact the lamp by rotating.

[0042] Specifically, a rotating column 1422 and a positioning column 1423 may be provided on the clamping block 142, and two positioning columns 1423 are symmetrically arranged on both sides of the rotating column 1422. The first plate body 141 is provided with a rotating hole 1412 for rotationally connecting with the rotating column 1422, and a positioning hole 1413 for positioning and plugging with the positioning column 1423. A threaded hole is provided at one axial end of the rotating column 1422, and a screw 1424 passes through the rotating hole 1412 and is connected with the threaded hole on the rotating column 1422. The outer diameter of the screw head of the screw 1424 is larger than the hole diameter of the rotating hole 1412, so that the clamping block 142 is locked on the first plate body 141.

[0043] Please refer to Figure 4Optionally, the two sides of the clamping block 142 are clamping surfaces of different shapes, and the clamping block 142 is detachably connected to the bottom block. The clamping block 142 contacts the lamp by switching different clamping surfaces through disassembly and assembly.

[0044] Specifically, the clamping block 142 can be plugged into the bottom block, such as Figure 4 In the embodiment, an insert block 1421 is arranged on the clamp block 142, a clamp block is arranged on the side of the insert block 1421, a plug hole 1411 for plugging with the insert block 1421 is arranged on the bottom block, and a clamp hole for plugging with the clamp block is arranged on the inner wall of the plug hole 1411. By changing the plugging direction of the insert block 1421 and the plug hole 1411, different clamping surfaces can be switched to clamp the lamp. Of course, it can also be detachably fixed to the bottom block using screws, and it is not limited to the two detachable fixing methods mentioned above.

[0045] In this embodiment, one side of the clamp block 142 is an arc-shaped clamping surface, and the other side of the clamp block 142 is a flat clamping surface. Therefore, it can be suitable for clamping lamps with rectangular or circular sides, and the clamping device for lamp testing has a wider range of application for clamping lamps.

[0046] Please refer to Figure 2 In this embodiment, an elastic cushion layer 147 may be provided on the clamping surface of the clamping block 142 to clamp the lamp more tightly and flexibly.

[0047] Please refer to Figure 2 In this embodiment, the bottom block includes a first plate body 141, a second plate body 143 and a third plate body 144 which are arranged in parallel. The second plate body 143 is located between the first plate body 141 and the third plate body 144. Orientation strips 134 are arranged on the two opposite inner walls of the slide groove 131a of the clamping frame 13. The first plate body 141 and the second plate body 143 are separated by a set distance so as to cooperate with the orientation strips 134.

[0048] The second plate body 143 and the third plate body 144 are separated by a set distance and an elastic block 145 is provided. The first screw member 146 is threadedly connected to the third plate body 144. The first screw member 146 contacts the bottom surface of the slide groove 131a, so that the second plate body 143 is squeezed and contacted with the directional strip 134, thereby fixing the position of the bottom block.

[0049] By setting a set distance between the second plate body 143 and the third plate body 144 and setting an elastic block 145 between the second plate body 143 and the third plate body 144, the third plate body 144 has an elastic deformation space, so that the threaded holes on the first screw member 146 and the third plate body 144 are not easy to slip, have a longer service life, and can also more stably fix the position of the bottom block.

[0050] Please refer to Figure 2In this embodiment, the elastic member is a tension spring 15, and a slide groove 131a for sliding connection with the clamping member 14 is provided on the clamping frame 13. The tension spring 15 is located in the slide groove 131a, and one end of the clamping member 14 is provided with a connecting hole 1431 for connecting with the tension spring 15.

[0051] The clamping frame 13 in this embodiment includes two cross-staggered fixing rods, and both ends of each fixing rod are connected to a clamping member 14 .

[0052] Please refer to Figure 5 In this embodiment, an end plate 132 for closing the port of the slide slot 131a is provided at the end of the fixed rod, and the rotating seat 12 includes two oppositely arranged columns 121, and a connecting column 133 is integrally formed on the end plates 132 at both ends of one of the fixed rods, and the connecting column 133 is rotatably connected to the column 121. A motor can be provided on the column 121, and the output end of the motor is connected to the connecting column 133, such as Figure 1 The middle motor may be disposed inside the column 121 .

[0053] The working principle of the clamping device for lamp testing of this embodiment is as follows: when the lamp needs to be clamped, the operator holds the lamp and squeezes the clamping member 14, so that the multiple clamping members 14 slide in the direction away from the center of the clamping frame 13 until the lamp is assembled between the multiple clamping members 14. The multiple clamping members 14 form a preliminary clamp on the lamp under the elastic tension of the tension spring 15, and then tighten the first screw member 146 to fix the position of the clamping member 14, thereby strengthening the clamping of the lamp by the multiple clamping members 14.

[0054] The following is a second embodiment of a fixture for lamp testing provided by the present invention that can solve the above technical problems. Compared with the first embodiment, the main difference of this embodiment is that the application range of the clamping member is improved by setting a sliding seat. The parts of this embodiment that are the same as the first embodiment will not be repeated.

[0055] This embodiment provides a clamping device for lamp testing, which is used to clamp the lamp and is placed in a darkroom. Light intensity detectors are arranged at different positions in the darkroom, and the multiple light intensity detectors are used to detect the light intensity of the lamp at various angles.

[0056] The fixture for lamp testing includes: a base 11, a rotating base 12, and a clamping frame 13. The rotating base 12 is rotatably arranged on the base 11 around a first rotating axis, and the clamping frame 13 is rotatably arranged on the rotating base 12 around a second rotating axis. The first rotating axis and the second rotating axis are skew intersecting. Through the rotational cooperation between the rotating base 12 and the clamping frame 13, the lamp clamped on the clamping frame 13 can be changed to multiple different angles, and light intensity detection in multiple different directions can be performed.

[0057] A plurality of clamping members 14 for clamping lamps are slidably disposed on the clamping frame 13 , and the clamping members 14 are connected to the clamping frame 13 via elastic members, which are used to drive the plurality of clamping members 14 to slide toward the center of the clamping frame 13 .

[0058] Please refer to Figure 6 In this embodiment, a sliding seat 21 is slidably provided on the clamping frame 13, and a guide groove for slidably connecting the sliding seat 21 is provided on the clamping frame 13. The sliding groove 131b is provided on the sliding seat 21, the clamping member 14 is slidably connected to the sliding groove 131b, and the tension spring 15 is connected between the clamping member 14 and the sliding seat 21.

[0059] It should be noted that the clamping member 14 is still the same as the first embodiment, and can include structures such as a first plate body 141, a second plate body 143, a third plate body 144, and a clamping block 142. The connection principle between the clamping member 14 and the slide groove 131b is consistent with the connection principle between the clamping member 14 and the slide groove 131a in the first embodiment.

[0060] Wherein, guide strips are arranged on two opposite inner walls of the guide groove, and the guide strips are similar to the orientation strips 134 in the first embodiment. Raised strips 211 are arranged on both sides of the sliding seat 21 .

[0061] An extrusion plate 22 is arranged between the sliding seat 21 and the bottom wall of the guide groove. The side of the extrusion plate 22 close to the sliding seat 21 is a first inclined surface 222. The sliding seat 21 is provided with a second inclined surface 2111 that is in surface contact with the first inclined surface 222. The inclination directions of the first inclined surface 222 and the second inclined surface 2111 are opposite.

[0062] An extension plate 221 is provided at one end of the extrusion plate 22. The extension plate 221 extends to one side of the end surface of the sliding seat 21 in a direction away from the guide groove. The end of the first inclined surface 222 away from the extension plate 221 is higher than the end close to the extension plate 221. The second screw member 23 penetrates and is threadedly connected to the extension plate 221. The second screw member 23 contacts the end surface of the sliding seat 21 to drive the extrusion plate 22 and the sliding seat 21 to slide relative to each other. When the sliding seat 21 is extruded and moves in a direction away from the extension plate 221, the total height of the extrusion plate 22 and the sliding seat 21 gradually increases, so that the convex strip 211 can be pressed and contacted with the guide strip, thereby fixing the position of the sliding seat 21.

[0063] Thus, by loosening the second screw 23, the position of the sliding seat 21 on the clamping frame 13 can be adjusted, thereby adjusting the distance between the multiple clamping members 14, and improving the application range of the clamping device. When the second screw 23 is tightened, the convex strip 211 can be pressed and contacted with the guide strip, thereby fixing the position of the sliding seat 21. In addition, there is a large area of ​​surface contact and extrusion between the extrusion plate 22 and the sliding seat 21, so that the convex strip 211 and the guide strip can also be in stable surface contact and extrusion, and the force is even, which can very stably fix the position of the sliding seat 21.

[0064] The fixture for testing lamps of the present invention can be adjusted to a plurality of different angles by the rotational cooperation between the rotating seat and the clamping frame, and can perform light intensity detection in a plurality of different directions, and the detection of the light intensity of the lamps is very comprehensive. At the same time, the plurality of clamping members on the clamping member can switch the clamping surfaces of different shapes to adapt to clamping lamps of different side shapes, and the clamping range of the plurality of clamping members can be adjusted, which is convenient for clamping lamps of different sizes and specifications, and has a wide range of applications.

[0065] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
