Why Should Elevators Be Equipped with a Light Curtain?
In modern elevator safety systems, the elevator light curtain has become an indispensable protective device. Using infrared detection technology, it creates an “invisible safety net” at the elevator door to effectively prevent accidents such as door entrapment or object pinching.
So why are more and more elevators being equipped with light curtains? What improvements do they bring in safety and user experience?
Today, A-FLY Elevator & Escalator Parts Supplier provides you with a detailed explanation.
1. How an Elevator Light Curtain Works
An elevator light curtain consists of two sets of infrared sensors — an emitter and a receiver, installed on both sides of the elevator door.
When the door closes, a dense grid of infrared beams forms between them.
If a person or object interrupts any of these beams, the system immediately detects the signal break and sends a command to the door control unit to reopen the door.
The entire process takes only a few milliseconds — much faster than traditional mechanical safety edges.
This means the light curtain can stop danger the moment before contact, providing a truly intelligent safety solution.
2. Why Add a Light Curtain to an Elevator?
Enhance Passenger Safety
The light curtain effectively detects passengers, luggage, strollers, or wheelchairs, preventing door entrapment and protecting vulnerable passengers such as children and the elderly.
Replace Mechanical Edges and Reduce Failures
Traditional mechanical safety strips rely on physical contact to send signals, making them prone to failure due to dust or aging.
In contrast, light curtains use non-contact sensing, offering higher stability, lower maintenance, and longer service life.
Improve Passenger Comfort
With a light curtain installed, the elevator door opens and closes more smoothly and responsively, eliminating discomfort caused by sudden door contact.
Comply with Modern Safety Standards
As international safety standards evolve, most new elevators now come equipped with light curtain systems, and retrofitting older elevators is becoming increasingly common.
Installing a light curtain not only improves compliance but also enhances the overall value and reliability of the elevator.
3. Types of Elevator Light Curtains and How to Choose
Based on beam density and sensing range, elevator light curtains are available in several types:
Standard Light Curtain: 32–94 beams, ideal for residential elevators.
High-Density Light Curtain: Over 160 beams, for commercial and high-speed elevators requiring high precision.
Waterproof Light Curtain: Sealed structure, suitable for outdoor or humid environments.
A-FLY’s Elevator Light Curtain Series uses high-sensitivity infrared modules and intelligent chip control for ultra-fast response and strong anti-interference capability.
Whether for new installations or modernization projects, A-FLY offers highly compatible product solutions.
4. Economic and Safety Value of Installing a Light Curtain
Many people think a light curtain is just an “extra feature,” but its long-term benefits are significant:
Reduces accident risk and maintenance costs.
Enhances the building’s safety reputation and user experience.
Improves property management efficiency.
Supports energy-saving and intelligent upgrade trends.
Installing a light curtain is not just a safety upgrade — it’s a key step toward intelligent elevator modernization.
