Abstract

Provided is a table lamp for illuminating a task area of a table. A plurality of light sources are provided, each with a different illumination direction toward the task area. A control arrangement is provided such that the plurality of light sources are controlled based on a position of the observer. Specifically, the control arrangement determines whether each light source meets criteria governing whether the observer may experience direct and reflected glare. Indeed, if a specular peak intensity angle of the light source is less than a reflected glare avoidance angle corresponding to a position of an observer, and a sight angle from the light source to the observer is greater than a direct glare avoidance angle corresponding to the position of the observer, then the light source may be controlled to illuminate the task area. In this way, specularly reflected light glare, as well as direct light glare, may be avoided.
