Handrail UV Sterilization Lamp
The UV sterilization lamp is designed for escalators and moving walkways. The short wave
270~285nm ultraviolet has the bactericidal effect. The principle of the UV sterilization
method is to damage the molecular structure of microbial cells (bacteria, virus and
other pathogens) DNA and RNA.
When the escalator is running, the UV light kills the bacteria on the handrail.
Sterilization rate >99%. The sterilization device is concealed on the return side under
the handrail to ensure passenger safety. Multiple sterilization devices can be installed
on the same escalator, based on the rise of the unit.
In case the of the handrail length 28m (92ft) and the running speed of 0.5m/s (3.3 ft/s),
one running cycle of the handrail is 56s and the residence time of the irradiation area is
0.2s. Since the cumulative effective sterilization time is 1min, escalator needs to
operate 4.6 hours to achieve the 99.99% sterilization effect.
This lamp must be installed inside the enclosed space. Reflector of the lamp goes through
the handrail. Luminous surface of the lamp faces the handrail. Distance of 10-15 mm
0.4-0.6 between handrail and lamp brings the best sterilization effect. If the
escalator pauses or stops, the lamp should be turned off accordingly.

1. Sterilization Distance: Vertical distance between light emitting surface of lamp and
2. The intensity of ultraviolet light decreases with the square of the distance of the LED
3. The effect of ultraviolet sterilization is related to irradiation time and distance.
The sterilization will be better if the irradiation time is longer and the distance is
