This article discusses the topic of "Automatic lighting control of objects", which is widely used in modern times and is developing rapidly. Issues such as lighting of roads and facilities in the dark, control of lighting in vehicles are one of the most pressing issues in our daily lives as well as security and control system design schemes. This area also includes schemes for the construction of smart homes. For example, in homes, offices, etc., depending on the amount of light falling. This includes the opening and closing of curtains and blinds, and the activation of irrigation systems at sunset for healthy plant growth. This area also includes the construction of roadside traffic signs.
In addition, we can create security systems for aircraft and other flight facilities by installing certain systems on high-rise buildings and towers using automatic lighting systems.
In general, one of the most pressing issues in the world is the automatic control of lighting systems, the use of lighting systems in control and security systems, and the use of lighting systems in similar areas. For example, in a few years of automotive technology, cars will have a full-fledged autopilot function, which will be more effective in terms of safety. In this regard, there are ready-made options offered by brands such as Quantoom, Premier, Giordon, which are called advanced systems that free the driver from the need to manually adjust the car's headlights. We can cite the advantages of these systems as economy and sustainability.
Modern automation systems are not only fashionable, but also have economic advantages:
• in the automatic mode the schedule is strictly observed, as the influence of the human factor is excluded;
• no need to go to check or turn off the lighting;
• If the lighting is not turned off, there is no power loss, as the dispatcher is immediately notified and takes appropriate action
• there is no need to go out and read the meters visually to perform technical energy measurements;
• telemetry allows you to immediately detect unauthorized connections to lighting networks and detect theft of electricity;
• With the help of telemetric measurements of voltages, currents and powers, it is possible to carry out initial diagnostics of the lighting network in case of any accident.
It is known that the application of automated control of outdoor lighting allows you to monitor the condition of telecommunications networks and street lighting devices, control lighting modes, remo¬te¬ly control street lighting according to a predetermined schedule, as well as keep records of lighting. A more reliable system built from modern components requires less maintenance costs.
The article also examines the circuits built in this area, the photoresistor element used as the main element in these circuits, its working principle, the physical structure of the photoresistor, operating logic, advantages and disadvantages. Also, the economic and safety advantages of automatic control of lighting systems were studied.
