Latest Patents

Yalong Liu's latest patents include a measurement method and device for light source parameters, as well as an illumination system and terminal apparatus. The method involves collecting signal values from a color sensor with at least six response channels. It includes preprocessing the collected signal values through normalization and standardization. The model features are constructed based on the preprocessed signal values, allowing for the determination of the light source type. This information is then input into a color rendering index prediction model to obtain the color rendering index of the light source being measured.

Another notable patent is a detection circuit, device, and method for detecting light source flicker, along with a photoelectric detection device. This detection circuit comprises a power supply and a photodiode that outputs a current based on the light source. The driving circuit, connected in series with the photodiode, generates an output voltage based on the current output by the photodiode, the power supply, and a resistive component. The control unit selects a circuit with a matched illumination correlation coefficient to maintain the output voltage within a designated range.
