Fundamental Understanding of Comb Plate Illuminance
The numerical combination "301x"-referring to the illuminance of the escalator's comb plates and tread plates-actually denotes a specific set of lighting parameters. As the transition zone for passengers' feet, the illuminance level of the comb plate directly impacts visual discernibility. Codes such as "301x" typically signify the following:
Base Illuminance Value: 30 lux
Measurement Point: Detection Zone No. 1
Dynamic Compensation Coefficient: "x" represents a variable adjustment range
Practical Considerations in Lighting Design
During escalator operation, it is essential to strike a balance between energy consumption and safety:
Focused Lighting in Transition Zones: The illuminance on the comb plates is set to be 15%–20% higher than that on the tread plates.
Ambient Light Adaptation: An automatic sensing system allows for brightness adjustments within a range of ±10%.
Anti-Glare Treatment: Diffuse light sources are employed to prevent direct, dazzling glare.
Application Logic for Specific Scenarios
The "301x" parameters play a pivotal role in the following scenarios:
High-Traffic Locations (e.g., Subway Stations): An "Enhanced Mode" is activated (x = 1.2).
Shopping Malls (Night Mode): Illuminance is automatically reduced to 70% of the base value.
Upon Triggering of Emergency Lighting: Illuminance is immediately boosted to 150%.
