Abstract

Method and device for thermal protection and management of light source are utilized in lighting industry, including street and traffic lights. According the method change of light source power supply is two-way controlled via thermal sensor, connected to control unit, which tracks light source temperature and regulates the supplied power. Method variants for operational and environmental information exchange with remote centre are developed. Advantages of method and device are luminary failures reduction due optimal operation; intelligent light source control; fast reaction to failures without additional expenses; data collection for statistical or other purposes.
