Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of passenger compartment lighting adjustment, and specifically provides a passenger compartment lighting adjustment control system. Background Art
[0002] The application of LED lighting technology in rail transit vehicles mainly benefits from its high energy efficiency, long lifespan, low maintenance cost, and rich color temperature adjustment capabilities. Compared with traditional lighting technologies, the energy consumption of LED lamps is reduced by more than 50%, and their lifespan can reach tens of thousands of hours, significantly reducing the frequency of replacement and maintenance. In addition, LED lamps have a wide range of color temperatures, which can be freely adjusted from warm white light (2700K) to cold white light (6500K), and can provide the most suitable lighting environment according to different scenarios and passenger needs. For example, in the early morning or at night, low-color-temperature warm light can be used to create a relaxing atmosphere; while in the daytime or in scenarios where concentration is required, high-color-temperature cold light can be used to enhance passengers' alertness and comfort.
[0003] With the improvement of people's living standards, passengers' requirements for travel experience have shifted from simple economy to comfort. Modern passengers not only hope that the train can arrive at the destination on time and safely, but also expect to enjoy more personalized services during the journey. Lighting, as one of the important factors affecting passenger comfort, requires more consideration of passengers' personalized needs in its design. Higher local brightness is needed for reading, while lower overall brightness is required for rest. However, the current rail transit lighting systems are mostly globally unified controlled and cannot meet the personalized needs of different passengers. Summary of the Invention

[0078] Example 1:
[0079] In this embodiment , = 476, and at this time the calculated 488. When the passenger uses the reading light, set 488 for illumination;
