Energy savings from photosensors and occupant sensors/wall switches on a college campus.
The key underlying factor contributing to poor performance (for example, underlit spaces) is the variability of the ratio of photosensor signal to daylight workplane illuminance (MD) with sun and sky conditions.
Within the expected range of experimental accuracy, the photosensor met the specified 44-45 degree FOV.
However, for lighting energy use comparisons, the lighting system introduced error into the energy use comparisons, primarily due to the differing photosensor response to the daylight distributions resulting from the innovative shading systems.
WattStopper announces the LMLS-600, a dual photosensor that automatically switches or dims one zone of lighting based on ambient light and daylight levels.
This suggests that daylight harvesting systems should consider photosensor placement at the top of monitor to improve user satisfaction while also avoiding many of the roadblocks to a desktop photosensor location.
The lighting fixtures in the occupied space, each with two lamps, are connected in banks of two to a combined occupancy and photosensor control mechanism.
One photosensor had a 60[degrees] cone of view and was pointed downward, normal to the floor.
IntenCity Lighting has filed five patents on new designs and engineering for it's reflector system, photosensor, power supply, mounting and cooling systems.
These are available with dual function occupancy and photosensor controls, Type V distribution and a claimed [L.
In addition, both sites included photosensors for daylight harvesting; later in the section we will comment on photosensor performance in the context of DR.
TAIPEI, Taiwan -- Avago Technologies, the world's largest privately held semiconductor company, today announced the industry's first color controller with an integrated color photosensor for backlighting liquid crystal displays (LCDs) for a variety of portable display devices.
