INTRODUCTION

Control

With the right presence detector, even warehouses

with high bay lighting can benefit from excellent

energy savings when the space is unoccupied.

Using absence detectors means the Thorn Hi-Rack

luminaires must be turned on when entering the

space – maximising energy savings.

Using digital dimming, Thorn’s Cruz luminaires take

measurements from sensors in the ceiling to establish the

task illuminance at desk or floor level and compare it to

the required lighting level. If there is too much light -

when the lamps are new, for instance - the luminaires

dim to save energy. As the lamps age, the dimming

reduces to keep the task illuminance correct.

Sensors built in to the Jupiter and Indiquattro

luminaires sense the change in daylight in the space,

and let the luminaires dim to save energy whenever

there is sufficient daylight. Intelligent software ensures

the lights do not react to short-term changes, such as

the sun drifting behind a cloud for a few seconds.

Task/Scene setting

Letting the user set scenes and

Using Thorn’s Titus Sport fitting in combination

with switching, the correct lighting level can be

chosen for a range of court uses, including

netball, basketball, badminton, football

and volleyball.

Timed off

Automatically turning all lights

off during unoccupied hours

Indra’s Bi power controls let the light level reduce

automatically when the amount of traffic falls late

at night. The luminaires still provide enough light to

navigate safely through the space, but save energy

by lowering their output.
