[0003] The existing side-emitting LED testing and light-collecting devices on the market have the following problems in actual use: In actual use, because the orientation of the LED beads is arbitrary in the PCB design of side-emitting LEDs, the existing LED light collection devices cannot accurately and completely collect the optical data of the LED due to the position of the components on the PCB board or the orientation of the LED. Utility Model Content
[0004] The purpose of this invention is to provide a side-emitting LED testing and light-collecting device to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A side-emitting LED testing and light-collecting device includes a PCB board and a light-collecting cover plate. A side-emitting LED is mounted on the surface of the PCB board, and a light-collecting cover plate is provided on the surface of the side-emitting LED. The bottom of the light-collecting cover plate is attached to the surface of the PCB board. A Lambertian cavity is formed inside the light-collecting cover plate, and the side-emitting LED is located inside the Lambertian cavity. A light-collecting opening is formed on the surface of the light-collecting cover plate.
[0006] Preferably, the light-receiving port is located outside the PCB board and penetrates the Lambertian cavity.
[0007] Preferably, the light-receiving port is located outside the side-emitting LED, and the light-receiving port is square.
[0008] The side-emitting LED testing and light-collecting device of this utility model has the following advantages: This device involves mounting a side-emitting LED on the surface of a PCB board and simultaneously providing a light-collecting cover plate on the surface of the LED. The bottom of the light-collecting cover plate is attached to the surface of the PCB board, and a Lambertian cavity is formed inside the cover plate. The side-emitting LED is located inside the Lambertian cavity. A light-collecting port is also provided on the surface of the cover plate. When using this device, the PCB board can be covered by the light-collecting cover plate until the side-emitting LED is located inside the Lambertian cavity. The LED can then be turned on, and the inner wall of the Lambertian cavity achieves sufficient refraction to form mixed light. The mixed light is output from the light-collecting port to an external spectrometer. This ensures the accuracy of the optical parameters collected by the spectrometer, solving the problem of existing spectrometers being unable to collect data from side-emitting LEDs.

A side-emitting LED 5 is mounted on the surface of the PCB board 4, and the light-collecting cover plate 1 is provided on the surface of the side-emitting LED 5. By installing the light-collecting cover plate 1, the light emitted by the side-emitting LED 5 can be collected. For convenient subsequent testing, it is very convenient to use. The bottom of the light-collecting cover plate 1 is attached to the surface of the PCB board 4, and a Lambertian cavity 3 is opened inside the light-collecting cover plate 1. The side-emitting LED 5 is located inside the Lambertian cavity 3, and a light-collecting port 2 is opened on the surface of the light-collecting cover plate 1. By installing and opening the Lambertian cavity 3, when using the device, the PCB board 4 can be covered by the light-collecting cover plate 1 until the side-emitting LED 5 is located inside the Lambertian cavity 3. Then the side-emitting LED 5 can be turned on. Then, the inner wall surface of the Lambertian cavity 3 achieves sufficient refraction to form mixed light. The mixed light is output to an external spectrometer through the light-collecting port 2. At this time, it can ensure that the optical parameters collected by the spectrometer are accurate, which solves the problem that the existing spectrometer cannot collect the data of the side-emitting LED beads.
[0022] The light receiving port 2 is located outside the PCB board 4 and passes through the Lambertian cavity 3. By installing the light receiving port 2, the mixed light can be output to an external spectrometer, which is very convenient to use.
[0023] The light receiving port 2 is located outside the side-emitting LED 5. The light receiving port 2 is square. By being located outside the side-emitting LED 5, it can easily provide output effects for mixed light, making it very convenient to use.
[0024] The working principle of this side-emitting LED testing and light-collecting device is as follows: When using this device, a side-emitting LED 5 is installed on the surface of the PCB board 4, and a light-collecting cover plate 1 is provided on the surface of the side-emitting LED 5. At this time, the bottom of the light-collecting cover plate 1 is attached to the surface of the PCB board 4, and a Lambertian cavity 3 is opened inside the light-collecting cover plate 1. The side-emitting LED 5 is located inside the Lambertian cavity 3. At the same time, a light-collecting port 2 is opened on the surface of the light-collecting cover plate 1. When using this device, the PCB board 4 can be covered by the light-collecting cover plate 1 until the side-emitting LED 5 is located inside the Lambertian cavity 3. Then the side-emitting LED 5 can be turned on. Then, the inner wall of the Lambertian cavity 3 achieves sufficient refraction to form mixed light. The mixed light is output to the external spectrometer through the light-collecting port 2. At this time, the optical parameters collected by the spectrometer can be ensured to be accurate, which solves the problem that the existing spectrometer cannot collect the data of the side-emitting LED beads. After the test is completed, the light-collecting cover plate 1 can be directly removed, which is very convenient to use.
