A high-output LED can deliver impressive luminous flux yet still produce an underperforming luminaire. Without controlled optics, light may spill beyond the target area, create glare, generate uneven illumination or demand a larger housing than the product brief...

A security light Fresnel lens is not simply a protective front cover. It is the optical element that determines where a passive infrared sensor can detect movement, how consistently it responds across its field of view, and, where lighting optics are involved, where...

A Fresnel lens for motion sensors is not a cosmetic cover placed in front of a detector. It is the optical element that defines where a passive infrared (PIR) system looks, how it divides a scene into detection zones and how effectively it converts movement into a...

A PIR detector that performs perfectly on a bench can miss movement at the edge of a corridor. A lighting optic can produce an impressive beam in simulation, then reveal colour variation, hot spots or unacceptable glare once fitted into its final housing. These are...

A motion detector mounted on a perimeter wall, car park column or exposed service enclosure faces a problem that indoor products rarely encounter: the optical field is continually changing. Direct sun, rain-cooled surfaces, moving foliage, vehicle exhaust and rapidly...
