Peripheral Lighting Supported Retrofit Compatible Miner Lighting System

Abstract

The invention relates to a human-centered lighting system that can be externally fitted to industrial helmets used in underground mining and similar hazardous work environments without requiring structural modifications. The system comprises a central focus light module providing forward-facing task lighting and lateral ambient lighting modules that support the user's environmental awareness. The central focus module and the lateral ambient lighting modules are independently driven by an electronic control unit and can be operated in different spectral modes. The system offers different lighting modes depending on the user's working conditions and biological needs. In the first operating mode, lighting with spectral characteristics that mimic natural daylight conditions and support alertness is provided. In the second operating mode, warmer spectral characteristics similar to a sunset are used to increase visual comfort and reduce eye strain. Controlled and gradual transitions are made between modes. The invention also incorporates a low-power emergency operating mode, a battery status indicator, and optical structures that control ambient lighting. Thanks to its retrofit-compatible mechanical structure, panoramic lighting architecture supporting peripheral vision, and spectral control capability compatible with biological rhythms, the system contributes to increased safety, awareness, and user comfort in underground working environments.
