The inverter system improves service life of a fluorescent lamp to reduce industrial waste, and reduces CO2 emission by saving power during the standby phase. We aim to always consider gentleness to the global environment.
Colored Display to Prevent Operation of the Wrong Button
The door open/close buttons and the intercom call button are distinguished from each other with different colors according to their functions, which prevents passengers from pressing the wrong button. Further, the markings and the button perimeter area of the "Door Open" button are designed to blink, enabling passengers to easily find the button when the doors are being closed.
Reduction in deterioration due to flickering of fluorescent lamp significantly contributes to extend lamp replacement cycle.
We not only employed an inverter system for the lighting system, but devised a way to suppress to the minimum level stresses on the electrodes while the lamp is on. In addition, by ensuring full-time light control, deterioration of fluorescer is inhibited, thus significantly extending the lamp replacement cycle. By realizing longer service life, which is a further advanced form of recycling, we can directly reduce industrial wastes, thus reducing environmental load.
Thanks to the dimmer control and optimal control methods for turning off the lights, power consumption was reduced to about one-fourth of conventional level.
Not only by saving power consumption when the lamp is on with the always-on dimmer control, but by reducing deterioration of electrodes caused by lighting, the time interval from a point that all call registrations are cleared to a point that the lamp is turned off automatically has been shortened. As a result, standby power is saved without impairing the service life of the fluorescent lamps. This means the annual power consumption for lighting can be reduced to about one-fourth compared to our conventional systems. When the saving is converted to CO2 equivalent, the reduction will reach about 69,000 liters per year (equivalent to about 234 drum cans).
* The energy saving effect is calculated under certain conditions, and the practical effect will be subject to the specifications and operating status of elevators. The CO2 equivalent figure is calculated base on materials from the Environment Agency of Japan.
