[0035] The present invention provides a light source test fixture, which is used to fix a light source 201 so as to test the light source 201. The light source 201 to be tested is specifically a patch light source, and the light source 201 includes a light-emitting side and a non-light-emitting side, and the light-emitting side and the non-light-emitting side are opposite to each other. Figure 4 The front surface of the light source 201 is the light-emitting side, and the rear surface of the light source 201 is the non-light-emitting side. Light is emitted from the light-emitting side, and the contact 401 for receiving power supply is arranged on the non-light-emitting side.

[0036] Reference Figures 1 to 5 The light source test fixture includes a mounting platform 102, a placement platform 103, a clamping member 104, a movable member 101 and an elastic member 301. The mounting platform 102 is used to mount the remaining components, and the placement platform 103 is connected to the mounting platform 102. The placement platform 103 can be used to place the light source 201. Figure 2 and Figure 4 The clamping member 104 is connected to the mounting platform 102, and there is an installation gap 402 between the clamping member 104 and the placement platform 103, and the installation gap 402 is for the light source 201 to enter, and the clamping member 104 can cover a part of the light-emitting side of the light source 201. Figure 2 The light source 201 is rectangular, and the circular area in the center of the light source 201 is the area where the LED light-emitting chip is installed. In order to reduce the blocking of light by the clamping member 104, the clamping member 104 actually covers the area of ​​the placement table 103 where the LED light-emitting chip is not installed.

[0037] Reference Figure 3 One end of the elastic member 301 is connected to the mounting platform 102, and the other end of the elastic member 301 is connected to the movable member 101. The elastic member 301 can be set as a spring ( Figure 3The spiral structure of the spring is not specifically shown). The movable member 101 includes a conductive portion 106, which can be set in a needle shape. The conductive portion 106 is electrically connected to a test device that supplies power to the light source 201 through a cable (not specifically shown). The conductive portion 106 can abut against the contact 401 to achieve electrical connection, so that the test device supplies power to the light source 201. The movable member 101 can move when a user applies a force to it, and the conductive portion 106 moves in a direction away from the clamping member 104; if the movable member 101 moves and resets under the elastic force of the elastic member 301, the conductive portion 106 moves in a direction close to the clamping member 104. In addition, it should be noted that the light source 201 is actually clamped by the conductive portion 106 and the clamping member 104, rather than being clamped by the clamping member 104 alone, or by the clamping member 104 and the placement table 103.

[0038] The following is a brief introduction on how to install the light source 201 on the light source test fixture and fix the light source 201. First, the user applies force to the movable part 101 (specifically, the user may press the movable part 101) to move the conductive part 106 away from the clamping part 104 to ensure that the light source 201 can enter the installation gap 402 and be placed on the placement table 103. Subsequently, the user places the light source 201 on the placement table 103. After the light source 201 is in place, the user stops applying force to the movable part 101, and the movable part 101 as a whole is reset due to the elastic force of the elastic part 301. Since the conductive part 106 abuts against the contact 401 of the light source 201 and the conductive part 106 moves toward the clamping part 104 under the action of the elastic part 301, the light source 201 will also move toward the clamping part 104. Refer to Figure 4 and Figure 5 Finally, the light source 201 will move to its light-emitting side and abut against the clamping member 104, and the conductive part 106 and the clamping member 104 will clamp the light source 201 from both sides of the light source 201 respectively, thereby fixing the light source 201; at the same time, the conductive part 106 abuts against the contact 401, realizing the electrical connection between the test equipment and the light source 201.

[0039] When the test is completed (after power is turned off to ensure safety), the user can apply force to the movable part 101 again so that the conductive part 106 no longer presses against the light source 201. The user can then pull the light source 201 out of the installation gap 402, thereby removing the light source 201 from the light source test fixture.

[0040] When preparing for the test, first apply force to the movable part 101, then place the light source 201 on the placement table 103, and then release the movable part 101 to fix the light source 201; after the test is completed, apply force to the movable part 101 again and then pull out the light source 201 to realize the disassembly of the light source 201. In addition, the conductive part 106 is used as a component for clamping the light source 201 and also as a component for realizing electrical connection. When the light source 201 is fixed, the electrical connection between the light source 201 and the power supply is also completed at the same time, and the electrical connection is also released when the fixation is released; in this way, when multiple light sources 201 are to be tested successively, it is not necessary to frequently disassemble and assemble the cables used for power supply, which is conducive to improving the test efficiency. The light source test fixture provided by the present invention is simple to fix and disassemble the light source 201, and the fixation of the light source 201 and the realization of the electrical connection are completed at the same time, and the disassembly of the light source 201 and the release of the electrical connection are completed at the same time, which is conducive to improving the test efficiency.

[0041] In some embodiments, the light source test fixture further includes a plurality of power supply circuits and a plurality of switches, the power supply circuits are used to be electrically connected to the test device 1103, each power supply circuit is electrically connected to two of the contacts 401 in the light source 201, the switch is connected to the mounting platform, each power supply circuit is connected to a switch, and the switch is used to turn on and off the power supply circuit. This arrangement can be used to test some relatively complex light sources, for example, to test a two-color light source.

[0042] The following is an introduction to the basic structure of a two-color light source. Fig.12 The dual-color light source includes two types of LED light-emitting chips (each type of LED light-emitting chip is provided with multiple), and the color temperature of the light emitted by the two LED light-emitting chips is different. For the convenience of description, one of the LED light-emitting chips is recorded as the first light-emitting element 1101, and the other is recorded as the second light-emitting element 1102. Multiple first light-emitting elements 1101 are connected in series, and multiple second light-emitting elements 1102 are connected in series. The dual-color light source usually has four contacts 401. If two contacts 401 are grouped, then in the same group, one contact 401 is used as the positive electrode and the other contact 401 is used as the negative electrode. The test equipment 1103 supplies power to the first light-emitting element 1101 through the first power supply line 1104, and the test equipment 1103 supplies power to the second light-emitting element 1102 through the second power supply line 1105. The dual-color light source has the following three operating modes: only the first light-emitting element 1101 is lit, only the second light-emitting element 1102 is lit, and both light-emitting elements are lit at the same time (the first two are single-channel operating modes, and the last one is a dual-channel operating mode).

[0043] Reference Fig.11 and Fig.12The light source test fixture includes a first switch 1001, a second switch 1002, a first power supply line 1104, and a second power supply line 1105. The first switch 1001 and the second switch 1002 are both mounted on the mounting platform 102, and the first power supply line 1104 and the second power supply line 1105 can be partially inserted into the mounting platform 102. There are four conductive parts 106, each of which is in contact with a contact 401; two conductive parts 106 are connected to the first power supply line 1104, and the other two conductive parts 106 are connected to the second power supply line 1105. The two contacts 401 connected to the first light-emitting element 1101 are both connected to the first power supply line 1104, and the two contacts 401 connected to the second light-emitting element are both connected to the second power supply line 1105. The first power supply line 1104 and the second power supply line 1105 are both connected to the test device 1103, and the test device 1103 supplies power to the light source 201 through the first power supply line 1104 and the second power supply line 1105. The first switch 1001 is connected to the first power supply line 1104, and the first switch 1001 is used to switch the first power supply line 1104 on and off, thereby controlling the power supply to the first light-emitting element 1101; the second switch 1002 is connected to the second power supply line 1105, and the second switch 1002 is used to switch the second power supply line 1105 on and off, thereby controlling the power supply to the second light-emitting element 1102.

[0044] When the first switch 1001 is turned on and the second switch 1002 is turned off, only the first light-emitting element 1101 is lit; when the first switch 1001 is turned off and the second switch 1002 is turned on, only the second light-emitting element 1102 is lit; when both the first switch 1001 and the second switch 1002 are turned on, both light-emitting elements are lit at the same time. In this setting, the light source test fixture can be used for testing in both single-channel operation mode and dual-channel operation mode, so there is no need to frequently replace other fixtures or jigs for testing different modes, thereby improving test efficiency. Fig.11 The mounting platform 102 is also provided with a wire hole 1003, through which cables can be passed, such as cables for monitoring parameters of the light source (these cables can also be electrically connected to the conductive portion 106).

[0045] The specific structures of the mounting platform 102, the placing platform 103, the movable member 101 and the clamping member 104 are described below.

[0046] Combination Figure 3 and Figure 6 The mounting platform 102 has a mounting cavity 302 inside, and the mounting platform 102 has a first avoidance hole 601, which is connected to the mounting cavity 302, and the movable member 101 is partially disposed in the mounting cavity 302, and the movable member 101 can enter and exit the mounting cavity 302 through the first avoidance hole 601. In addition, referring to Figure 3, the elastic member 301 can be installed in the installation cavity 302, and the cable for connecting with the conductive part 106 can be passed through the installation cavity 302. The movable member 101 is partially accommodated in the installation cavity 302. Such an arrangement can make the structure of the entire light source test fixture more compact and reduce the volume of the light source test fixture. Correspondingly, under this arrangement, in order to match the position of the conductive part 106 with the position of the light source 201 on the placement table 103, the placement table 103 is located outside the installation cavity 302, and the placement table 103 blocks the first avoidance hole 601, and the placement table 103 is provided with a second avoidance hole 105, and the second avoidance hole 105 is for the conductive part 106 to pass through the placement table 103 (the second avoidance hole 105 is a through hole).

[0047] Reference Figure 3 and Figure 7 , the movable member 101 also includes a holding portion 701, which is connected to the conductive portion 106, and the holding portion 701 is the part of the movable member 101 for the user's finger to hold, that is, the force applied by the user to the movable member 101 is a pressure. At least a part of the holding portion 701 is arranged outside the mounting cavity 302 for the user to contact. In other embodiments, the user can also drive the movable member 101 to move in a direction away from the clamping member by pulling the movable member 101 (correspondingly, a part of the movable member 101 needs to extend from the rear side of the mounting platform 102 in order to be pulled). Relatively speaking, the movable member 101 is set to be driven by holding, which is more convenient for the user to use the light source test fixture, because the position of the holding portion 701 for the user to press is close to the light source 201, and the steps of pressing the holding portion 701 and other installation of the light source 201 can be completed on the front side of the mounting platform 102.

[0048] Reference Figure 6 and Figure 8 The mounting platform 102 is further provided with a mounting groove 604, and the first avoidance hole 601 is located at the bottom wall of the mounting groove 604, that is, the mounting groove 604 and the mounting cavity 302 are connected through the first avoidance hole 601. Figure 1 , the side wall of the mounting groove 604 can abut against the edge of the holding portion 701, thereby positioning the holding portion 701. The side wall of the mounting groove 604 not only positions the holding portion 701 during assembly of the light source test fixture itself, but also positions the movable part 101 when the movable part 101 moves (equivalent to guiding the holding portion 701 during movement). In addition, the wall surface of the mounting cavity 302 can also guide the movement of the holding portion 701; similarly, referring to Figure 4 and Figure 5 When the hole wall of the second avoidance hole 105 can abut against the outer edge of the conductive part 106 (the sizes of the second avoidance hole 105 and the conductive part 106 need to match), the hole wall of the second avoidance hole 105 can also guide the movement of the conductive part 106 .

[0049] Reference Figure 6 The mounting platform 102 further includes a positioning body 605, one end of which is connected to the side wall of the mounting groove 604, and the other end of which protrudes into the mounting groove 604. Figure 8 and Fig. 9 The placement table 103 is provided with a positioning opening 902, into which the positioning body 605 is inserted, and the wall of the positioning opening 902 abuts against the positioning body 605, thereby achieving the positioning between the placement table 103 and the mounting table 102. In addition to the cooperation between the positioning opening 902 and the positioning body 605, the placement table 103 can also be positioned by other methods. Figure 6 and Figure 8 The mounting groove 604 includes a first accommodating portion 603 and a second accommodating portion 602 that are interconnected. The first accommodating portion 603 and the second accommodating portion 602 are distributed along the length direction of the mounting groove 604, and the width of the first accommodating portion 603 is smaller than that of the second accommodating portion 602. The wall surface of the second accommodating portion 602 at one end close to the first accommodating portion 603 abuts against the outer edge of the placement platform 103, thereby positioning the placement platform 103. The side of the first accommodating portion 603 is used to abut against the outer edge of the holding portion 701, thereby positioning the holding portion 701.

[0050] It should be noted that both the positioning body 605 and the end wall of the first receiving portion 603 are used to perform a preliminary positioning of the placement platform 103. The placement platform 103 and the mounting platform 102 are fixed by the connection between the clamping member 104 and the mounting platform 102. Figure 1 and Figure 6 , the clamping member 104 is connected and fixed to the positioning body 605 by means of screws 107. Since the clamping member 104 covers a part of the placement platform 103, after the clamping member 104 is fixed to the positioning body 605 of the mounting platform 102, the placement platform 103 cannot be separated from the mounting platform 102 under the blocking effect of the clamping member 104, thereby achieving the fixation between the placement platform 103 and the mounting platform 102. It should be noted that after the clamping member 104 is connected to the mounting platform 102, an installation gap 402 is formed between the clamping member 104 and the placement platform 103; when the light source 201 is subsequently mounted on or removed from the fixture, the screws 107 used to fix the clamping member 104 do not actually need to be loosened or tightened, and the size of the installation gap 402 is also unchanged, and the clamping and loosening of the light source 201 is mainly achieved by the movement of the conductive part 106. Under the elastic force of the elastic member 301 , the conductive portion 106 can be pressed against the contact 401 to avoid poor contact (for example, when the conductive portion 106 is pressed against the contact 401 , the elastic member 301 is still in a compressed state).

[0051] Reference Figure 7The pressing portion 701 also includes an avoidance groove 702, which is used to accommodate the placement table 103. The conductive portion 106 passes through the bottom wall of the avoidance groove 702 and extends into the avoidance groove 702. When the pressing portion 701 is not pressed by the user's finger, the pressing portion 701 moves in the direction away from the installation cavity 302 under the elastic force of the elastic member 301, and the placement table 103 will abut against the bottom wall of the avoidance groove 702 to prevent the pressing portion 701 from continuing to move away from the installation cavity 302. After the placement table 103 abuts against the pressing portion 701, the placement table 103 is set in the avoidance groove 702. Compared with the case where the avoidance groove 702 is not set, the above setting can make the structure of the light source test fixture more compact, and the abutment between the placement table 103 and the side wall of the avoidance groove 702 also guides the movement of the movable part 101.

[0052] Reference Figure 8 The placement table 103 is also provided with a light source positioning groove 801, which is used to accommodate the light source 201 so as to position the light source 201. The side wall of the light source positioning groove 801 abuts against the edge of the light source 201 to achieve positioning. The second avoidance hole 105 is located on the bottom wall of the light source positioning groove 801. Figure 1 , Figure 2 and Fig. 9 , the tip of the clamping member 104 is spaced from the bottom wall of the light source positioning groove 801, thereby forming an installation gap 402. To facilitate the light source 201 to enter and exit the light source positioning groove 801, one side of the light source positioning groove 801 extends to the edge of the placement table 103 to form a disassembly opening 901, and the light source 201 can enter and exit the light source positioning groove 801 through the disassembly opening 901. Under this arrangement, when placing the light source 201, there is no need to change the position of the clamping member 104, and only needs to press the holding portion 701 to leave enough space for the light source 201 to enter the light source positioning groove (if the holding portion 701 is not pressed, the conductive portion will extend into the light source positioning groove 801 and block the light source 201), which makes it more convenient to install the light source 201.
