Description

Technical Field

[0001] The utility model relates to the technical field of optical testing, in particular to an illumination testing tool. Background Art

[0002] The illumination test of traditional LED lamps usually relies on a simple test fixture, and the test process needs to be completed in a dark room without windows. The simple fixture consists of a bottom plate, a left plate, a right plate, and a rear plate to form an open box structure, and a shelf for placing LED lamps on the top. When testing, first fix the LED lamp on the shelf and turn on the power, and then place the test equipment on the bottom plate of the box structure. Next, make sure all other light sources in the room are turned off so that the light intensity data of the LED lamp can be recorded in an interference-free environment.

[0003] The use of a closed light-proof box can reduce the requirements for environmental conditions in illumination testing. For example, the device disclosed in the Chinese utility model patent "A desk lamp uniformity test device" with application number 202222191766.5 (authorization announcement number CN 217845589 U) includes a closed light-proof box, a mounting seat, and a light-emitting component. The mounting seat is fixed on the upper cover of the box through the mounting seat, and light outlets are respectively provided on both sides of the mounting seat, and a mounting groove is provided on the upper end of the mounting seat outside the light outlet. The light-emitting component includes an LED light bar and a light guide plate. The bottom of the light guide plate is placed in the mounting groove, and the LED light bar is fixed on the mounting seat on one side of the light guide plate. The incident light emitted is incident on the light guide plate from the side and emits light from the light outlet into the box.

[0004] However, the mounting structure of the device for mounting the lamp to be tested lacks an adjustment function, which makes the device less flexible in adapting to the testing of LED lamps of different specifications. Utility Model Content

The carrier board cover is arranged on the through hole of the top plate of the box body, and the carrier board and the top plate of the box body can be separated. The bayonet of the carrier board corresponds to the position of the through hole, so that the light emitted by the lamp to be tested can be irradiated into the box body.

[0010] Compared with the prior art, the utility model does not directly adjust the size of the through hole opened on the top plate, but adopts a carrier plate with a bayonet to cooperate with the through hole as the installation structure of the lamp to be tested. The bayonet shape of the carrier plate is customized according to the specifications of the lamp to be tested. By replacing different carrier plates, lamps to be tested of different specifications can be adapted, which makes the installation structure of the illumination test tooling adjustable.

[0011] In order to effectively control the test variables, further, the top plate of the box body is provided with a positioning structure for positioning the carrier plate, so that each time the carrier plate and the lamp to be tested carried by the carrier plate are replaced, they can be put back to the last test position.

[0012] There are multiple optional schemes for the positioning structure. Preferably, the top plate of the box body is provided with a groove opening upward, the through hole is opened at the bottom surface of the groove, the bottom surface of the groove is slightly larger than the carrier plate, and the groove serves as the positioning structure to position the carrier plate in the groove.

[0013] To prevent the carrier plate from rotating, further, the bottom surface of the groove is rectangular, and the carrier plate is also a corresponding rectangle.

[0014] In order to obtain comprehensive test data, a plurality of photosensitive probes for testing illumination are arranged in the box, and the photosensitive probes are distributed on the bottom plate and four side plates of the box, so that the illumination at the bottom and the side can be measured.

[0015] Furthermore, 9 photosensitive probes are distributed in a nine-square grid on the bottom plate of the box.

[0016] Furthermore, five photosensitive probes are distributed in an "X" shape on each side panel of the box.

[0017] In order to ensure the opacity of the box, as a preferred solution of the utility model, the box is surrounded by matte black painted plywood.

[0018] Compared with the prior art, the utility model uses a carrier plate with a special bayonet and a through hole to form an installation structure for installing the lamp to be tested. The bayonet of the carrier plate is precisely designed according to the specific specifications of the lamp to be tested, and the carrier plate and the box body are easy to separate. By replacing different types of carrier plates, it can adapt to lamps of various specifications to be tested. This design not only improves the adaptability of the illumination test tooling, but also simplifies the installation process of the lamp to be tested, making the test work more efficient.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 to Figure 6 As shown, it is a preferred embodiment of an illumination testing tool of the utility model.

[0027] The illumination test tool comprises a box body 1 and a carrier board 2 placed on the box body 1. The box body 1 is enclosed by matte black painted plywood to ensure that it is lightproof. The carrier board 2 has a bayonet 21, which allows the lamp to be tested to pass through and allows the lamp to be tested to be snapped into the carrier board 2. The shape and size of the bayonet 21 are customized according to the specifications of the lamp to be tested. When the lamp to be tested needs to be replaced, it is only necessary to separate the carrier board 2 carrying the lamp to be tested from the box body 1 and remove it, and then replace it with a carrier board 2 with a different bayonet 21 model and carrying a new lamp to be tested.

[0028] Since the carrier board 2 needs to be removed frequently, providing a positioning structure for the carrier board 2 helps ensure that the environmental conditions for each illumination test are substantially the same. In this embodiment, the top plate 11 of the box body 1 is provided with a groove 14 opening upward, and the bottom surface of the groove 14 is slightly larger than the carrier board 2, which is used as a positioning structure for positioning the carrier board 2. The shape of the groove 14 and the carrier board 2 is rectangular, or other polygonal, which can prevent the carrier board 2 from rotating.

[0029] The top plate 11 of the box 1 is provided with a through hole 15, which is located at the bottom surface of the groove 14, and its position corresponds to the bayonet 21 of the carrier board 2, so that the light emitted by the lamp to be tested can be irradiated into the box 1, and these lights are received by the photosensitive probe 16 pre-buried in the box 1, so that the illumination of the lamp to be tested can be measured. In the test state, the through hole 15 is completely blocked by the carrier board 2 and the lamp to be tested, and the external ambient light will not enter the box 1, so as to avoid affecting the test results.

[0030] This embodiment also improves the distribution of the photosensitive probes 16. There are a plurality of photosensitive probes 16, which are distributed on the bottom plate 12 of the box 1 and the four side plates 13 of the box 1, and can more comprehensively detect the illumination of the lamp to be tested. Nine photosensitive probes 16 are arranged on the bottom plate 12 of the box 1, and these nine photosensitive probes 16 are arranged in a nine-square grid. Five photosensitive probes 16 are arranged on each side plate 13 of the box 1, and these five photosensitive probes 16 are arranged in an "X" shape.

[0031] The operation method of this embodiment is as follows: connect the lamp to be tested to the carrier board 2 with the corresponding specification bayonet 21, and then place the carrier board 2 carrying the lamp to be tested into the groove 14 opened on the top plate 11 of the box body 1, and then turn on the power of the lamp to be tested to make it emit light, and the light is fully sensed by the photosensitive probe 16 in the box body 1, and the photosensitive probe 16 is electrically connected to the data panel outside the box body 1, and the user can read the illumination data of the lamp to be tested through the data panel. Take out the download board 2, replace it with a new carrier board 2 carrying another lamp to be tested, and repeat the above steps, so that the illumination of multiple lamps to be tested can be accurately and conveniently detected.
