Hi, I'm looking for information on the connection between smooth lighting control according to a time schedule and the "constant light control" type (artificial light illuminating natural light to a pre-set level of e.g. 1000 lux). I have written some information on this, as below, but it is very little, could someone who knows say some details on how it is with LED lighting. The information on the Polish and English websites mainly serves to promote the products, so instead of technical information and explanations, only generalities are given, expressed in the language of benefits 
Thank you in advance for any information or advice.
The control of lighting according to time schedules and ambient light levels is the subject of this work. It is an improvement on the previous subsection, as the work also considers the activity schedule of the device. Time-scheduled lighting control is used to reduce the operating time of a lighting installation. The time schedule most often depends on the anticipated presence of people in the rooms where the lighting installation is operating. In this way, the saving of electricity consumption does not depend solely on the will of the user. In a classic lighting installation, the artificial lighting should be switched off at around midday, but this usually goes unnoticed and is eventually switched off when the user remembers. The control provides the set lighting intensity for the workplace, not the light source. The system controls the LED luminaires in analogue mode so that a preset illuminance sensor reading is obtained.
For example, I know that this involves communicating a real-time clock with the light sensor and should be done via an I2C interface, I don't know what to add next
