Introduction

  1. The elevator lobby is like the nerve center of the building as all traffic passes through it.
  2. Maintaining a certain level of brightness for the elevator lobby is an absolute must, but energy saving must also be taken into consideration.

Traditional Approach

shortcomings with timers
Timer based approach shortcomings:
  • When the time set is too short - it is inconvenient to the user.
  • When the time set is too long - it wastes energy.
  • Outside of the set times, it cannot be used even when needed.
shortcomings with sensors
Traditional sensors shortcomings:
  • The lights turn on and off too frequently, which causes wear and tear on both the lights and the sensors
  • The lights are off when no one is around, which causes unease and is also unsafe. There is no directional guide and the building loses its warmth.
  • Having the lights turn on abruptly is jarring to the eyes.

  2. Lights can also be turned on/off manual through the wall switch
  3. The photo sensitivity can be adjusted so it doesn't switch on when not needed
  4. The auto off delay time is also adjustable

K24 Wall Mounted

  1. Person comes, lights auto on; person leaves, lights auto off
  2. Lights can also be turned on/off manual through the wall switch
  3. The photo sensitivity can be adjusted so it doesn't switch on when not needed
  4. The auto off delay time is also adjustable

(3) Sensor Dimming

K81 Functionality
  • Normally half dimmed, when sensor detects occupant it gradually brings the light back up to full brightness.
  • When the occupant leaves, the sensor slowly returns the lights to half dimness giving a soft and elegant effect.
  • The half dimness level can be adjusted by the user according to the needs of the surroundings.

Peak Period: Lights fully lit.

Off-Peak Period: Half dimmed, when sensor detects an occupant, the lights gradually go to full brightness.
