The Challenge: Inefficient Lighting at Metro Station Entrances
Metro station entrances are among those urban spots that experience high influx. Being among the busiest places in the city, maintaining appropriate lighting at all times is one of the necessities here. At the same time, ensuring energy-efficiency while guaranteeing safety is another priority. Without excessive use of power, the safety of pedestrians must be ensured and enough visibility needs to be provided. In view of these goals, metro station entrances have a unique set of challenges:
- Excess daylight leads to unnecessary lighting, wasting energy when it is actually not needed and manual intervention is required all the time
- Cloudy weather often lacks light adjustment, risking visibility issues and jeopardising safety
- Manual control systems demand frequent maintenance leading to excessive costs and downtime
- Lack of smart environmental sensing limits lighting responsiveness making it into a stagnant system that requires frequent manual operation
These factors call for a smart, automatic, and low-maintenance metro entrance lighting control solution that ensures efficiency and reliability across varying environmental conditions and doesn’t cost a lot in terms of maintenance and power usage.
The Solution: Intelligent Photocell Control by Lead-Top
To deal effectively with the above mentioned challenges, Lead-Top photocell controllers offer specialized photocells for subway lighting. They feature precise light sensing under varying weather conditions, automatic switching according to ambient light levels, surge protection for optimal operation even under unreliable conditions, and weather resistance to ensure longevity, making them ideal for metro entrances, pedestrian tunnels, and below-ground structures. They enhance security and ensure cost-effectiveness along with reducing the need for manual intervention. This is the type of automation needed for metro station entrances.
Recommended Models
From ensuring quick response to providing highly durable certified hardware components, Lead-Top light controllers boast unmatched features. We have a series of models that are specifically suitable for metro station entrances.
Below are the models that are ideal for metro stations along with key features and recommended use cases.
| Model | Key Features | Ideal Location |
| LT310C | Fast-response electronic type | Ceiling junction boxes |
| LT124L | NEMA twist-lock, tool-free replacement | High-mast or pole fixtures |
| LT1SC | Shorting cap for testing/emergency use | Maintenance zones |
Installation & Operation Logic
To get the best out of Lead-Top’s smart lighting controller for transit systems, it is important that the installation is done properly, keeping in view all the requirements. Below is a brief explanation of how these outdoor LED dusk-to-dawn sensors should be deployed for best results and error-free operation.
1. Wiring Method: Connect the photocell in series between AC power and the LED luminaire.
2. Placement Tips:
Mount the photocell facing north or face it towards a shade. This helps avoid false activation from light reflection and the photocell sensors are not abruptly triggered due to false stimuli, ensuring energy efficiency and uninterrupted operation.
These photocells are suitable for wall-mounted deployment, installation on canopies, or pole lighting near metro entrances.
3. Time Delay Function:
These outdoor LED dusk to dawn sensors by Lead-Top come with time delay function and adjustable LUX threshold settings on demand. Setting an appropriate time delay and LUX threshold can go a long way in adapting their operation according to the ground conditions. These customization options make the photocells practically viable. Here is what we recommend regarding these settings:
- 3–6 second delay prevents false triggers from headlights or lightning. This helps avoid flickering and interruptions
- Customizable LUX thresholds can help adjust on and off timing according to the ambient light on ground, maximizing energy savings and safety
Both these customization functions can be ordered and are provided on demand.
