Frequently asked questions
Cleanrooms require special recessed LED luminaires with IP65 protection and a smooth, crevice-free surface. Illuminance of 500-1000 lx depending on the cleanliness class. For pharmaceutical and electronics applications, we use luminaires with laminar air flow. Materials must be chemically resistant, easy to clean, and non-particle-releasing. Light sources with low UV emission for sensitive processes. Emergency lighting integrated into the main luminaires.
For 24/7 operation, we select LED luminaires with an extra-long lifespan of 100,000+ hours and minimal degradation. We implement Human Centric Lighting - the night shift has higher intensity (750-1000 lx) and cooler light (5000 K) to maintain alertness. The morning shift gets a gradual ramp-up from 4000 K to 5000 K. Redundant power supply ensures uninterrupted operation. Predictive maintenance via IoT sensors reports approaching failures. Energy management optimizes consumption.
Quality control requires high illuminance of 1000-1500 lx with excellent colour rendering CRI>90 (ideally CRI>95). For defect detection, we use various light angles - direct, lateral, and backlight. Shadow-free lighting from multiple sources eliminates hidden defects. For electronics, antistatic LED luminaires. Magnifying lamps with integrated LED lighting for micro-assembly. Stroboscopic LEDs for inspecting rotating parts. UV light for fluorescent inspection.
Robotized workplaces need flexible lighting. Machine vision requires constant illumination without fluctuation - LEDs with high-quality drivers and no flicker. Infrared or UV lighting for special detection. Synchronization of stroboscopic light with the robot camera. Light curtains and signalling for safety zones - red=stop, yellow=warning, green=OK. Industrial Ethernet for integration of lighting into the control system. Adaptive lighting that changes according to the production phase.
Emergency lighting must ensure safe evacuation - a minimum of 1 lx on escape routes and 5 lx at exits. Operating duration is at least 1 hour, 3 hours for hazardous operations. Automatic functionality testing every month. For dangerous processes, emergency lighting provides safe completion/shutdown of production (10% of normal illumination). Central battery system or individual batteries in each luminaire. LED emergency luminaires have low consumption and long battery life.
