Open Office Lighting System Based on Mixed Lighting

Abstract

The invention provides an open office lighting system and control method based on hybrid lighting. The system includes a user interface unit, a light color sensing unit, a control unit, and a dimmable lamp group composed of a ceiling lamp and a desk lamp. Offline establishment of evaluation criteria such as dimming lighting distribution model, light color scoring model, and user registration form; when the preset conditions are met in online control, when optimizing lighting according to the current natural light conditions and evaluation standards, first based on energy consumption, aisle Illuminance, illuminance uniformity, gradient and other indicators optimize the parameters of the dimmable ceiling lamp, and then optimize the parameters of the dimmable table lamp based on the scores of the users in the office and energy consumption indicators, and the optimization results are sent to the driver for adjustment The lamp group emits light to realize the comprehensive and optimized lighting of the open office. The present invention can also take into account the comfort of the overall space while considering the user's lighting preference, and can dynamically adjust the lighting according to the sunlight, so as to create a comfortable, energy-saving and personalized lighting environment for the office.

Description

technical field [0001] The patent of the invention belongs to the field of intelligent lighting, and specifically relates to an open office lighting system and control method based on hybrid lighting. Background technique [0002] In an office building, employee efficiency and success depend heavily on communication. Most activities performed in an open office include tasks that require computer processing. For computer workplaces, it is essential to ensure that the strain on the eyes constantly switching back and forth between the screen, the work material and the surrounding environment is kept to a minimum, and the need for drastic contrast adjustment and adaptation should be avoided. Therefore, it is important to avoid direct light and reflected glare in an open office. Reflected glare is produced by bright surfaces such as windows or light fixtures reflecting off screens, so these offices should optimize workstation placement relative to windows and be shaded by curta...

AI Technical Summary

Problems solved by technology

However, office lighting is a complex system. It is mainly aimed at the supplementary lighting of employees during the daytime in the office, and also takes into account the lighting at night; and the lighting experience itself is closely related to people's psychological and physiological activities. Different individuals have expectations for lighting. There is a significant difference; moreover, the ambient light is constantly changing with time, and the traditional control method of dimming according to a limited number of modes cannot meet the individualized lighting needs of office workers
