Abstract
Previous work demonstrated a retrofit proximity detector for fluorescent lamps using the lamp's own stray electric fields. This paper extends the retrofit sensor system to a solid-state (LED) lamp. The design and implementation of a suitable driver ("ballast") for the LED lamp is presented. Design considerations for the ballast include those relevant to lighting (e.g. color cast and dimming levels) as well as those relevant to sensing of human occupants. Two electro-quasistatic modeling approaches for the lamp sensor are discussed. Experimental data from the LED lamp sensor are presented and compared to one of the proposed quasistatic models.
