Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

As shown in Figures 1-8, the present invention discloses a spectrometer for detecting quantum optical materials, including a spectrometer housing 100, the spectrometer housing 100 is used to protect an internal optical integrator, a cavity is set in the spectrometer housing 100 to form a darkroom 102, the spectrometer housing 100 is installed above a detection platform 200 through a support rod 130, the support rod 130 serves to support the optical integrator and the darkroom 102, an optical integrator assembly is set in the spectrometer housing 100, a backlight assembly is set in the detection platform 200, and the optical integrator assembly cooperates with the backlight assembly to detect quantum optical materials.

The backlight component is composed of four different wavelength color LEDs, RGBW, which can meet the color coordinate requirements of the light spectrum CIE. By controlling the light intensity of RGBW separately, the backlight color coordinates of the client LCD can be adjusted. There is no need to assemble it into a 2cm whole machine and then measure the brightness/color coordinates/color saturation.

Currently, CA210/CA310/CA410 are generally used in the market for optical measurement, which can only measure brightness and color coordinates, but cannot directly measure color saturation.

R, G, B, W four independent adjustable light sources, can simulate all current international color saturation standards LCD switching carrier 120, LCD switching carrier 120 is installed with a layer of LCD glass, can measure the color coordinates of a single quantum material separately (when not choosing to pass through LCD glass)

When the light source is selected to pass through the quantum dot material and then through the LCD glass, the saturation of the LCD can be simulated.

When the device is used, the user places the quantum optical material to be detected on the surface of the detection platform 200, and then starts the optical integrator component and the backlight component to detect the quantum optical material.

The optical integrator assembly includes an optical integrator computer 300 and an optical integrator lens and controller 310. The controller is used to control the extension and retraction of the optical integrator lens. The optical integrator lens and controller 310 are installed in the spectrometer housing 100 with the lens facing downward. The optical integrator computer 300 is located in the detection platform 200.

The backlight assembly includes a WRGB backlight lamp sheet 212 and a WRGB backlight lampshade 213. The WRGB backlight lampshade 213 is used to converge and mix the light source. The inner surface of the WRGB backlight lamp sheet 212 is coated with a high-reflective resin to avoid backlight energy loss. The WRGB backlight lamp sheet 212 is installed at the lower end of the WRGB backlight lampshade 213, and the WRGB backlight lampshade 213 is in a truncated cone shape. The larger end of the WRGB backlight lampshade 213 faces downward, and the smaller end of the WRGB backlight lampshade 213 faces upward to form a backlight light outlet 221.

A light bar 101 is installed at the front end of the spectrometer housing 100. When the device is running, the light bar 101 can emit light to serve as a prompt to the user.

A darkroom fixing screw 110 is provided on one side of the spectrometer housing 100. The use of the darkroom fixing screw 110 can prevent the darkroom 102 and the optical integrator from falling onto the detection platform 200. An LCD switching carrier 120 is installed on the other side thereof for selecting single product detection or LCD detection.

A support rod through hole 131 is opened inside the support rod 130 so that the support rod 130 has a hollow structure, and the lower end of the support rod 130 is inserted into the detection platform 200, and the upper end thereof is inserted into the spectrometer housing 100. The hollow tube design can facilitate the control line to pass through for use.

The front end of the detection platform 200 is provided with an LCD RGB switching button 210, and the LCD RGB switching button 210 is used to switch the LCD color. A WRGB LED brightness control knob 211 is provided on one side of the detection platform 200. When testing samples, this device provides four backlight colors with different wavelengths. The color types are developed and matched, and the spectrum colors of the full color range can be adjusted. There is no need to switch LEDs of different wavelengths to shorten the sample testing time.

The upper end of the detection platform 200 is covered with a detection platform anti-scratch pad 220, which can protect the sample from scratches.

The detection platform 200 is a box-type structure, and the quantum optical material is placed on the upper surface of the detection platform 200 .

When this application is implemented, a set of self-developed full-spectrum LED light sources are built in, using 12000k white light, 450nm blue light, 530nm green light and 630nm red light as a combination of all color gamut light sources, which can meet all different backlight requirements of different customers and different displays. By selecting the backlight of LED wavelength, different customer needs can be met.

Each monochromatic LED wavelength can serve as the excitation light source for the main quantum dots, and match the other three LED light sources at the same time. This combination can meet the spectral detection of different quantum dot materials. (Quantum dot materials are a type of nano-level semiconductor material that produces light. Because different particle sizes have different energy levels, they can correspond to different luminescence wavelengths. There are many different quantum dot materials on the market, and the required excitation wavelengths are different).

Operation method:

1. Turn on the power supply;

2. Open the light source protection cover;

3. Brightness calibration: adjust the backlight color coordinates and brightness to be consistent with the customer's backlight brightness and color coordinates (Note: You can use a illuminance meter or light energy meter as a reference. It is recommended to use a brightness meter under white light conditions and an optical power meter under blue light conditions);

4. Place the sample to be measured in the testing port, and move the darkroom 102 downward to the height of the testing platform;

5. Press the LCD screen switch button. (Press the down button to switch);

6. Click the measurement button on the computer (detect color from W/R/G/B, measure in sequence);
