Final answer:
Occupancy Sensor controls are not ideal for bollards on pedestrian walkways due to frequent and unrelated motion. Time-based controls or louver controls are more suitable due to their non-reliance on motion detection.
Step-by-step explanation:
The type of lighting controls technology that does not work well with bollards on pedestrian walkways is c. Occupancy Sensor controls. These sensors typically rely on detecting motion or presence to turn lights on or off, and bollards are often used in outdoor settings where motion is frequent and can be unrelated to the need for lighting, thus making it challenging for occupancy sensors to accurately control the lighting. For example, a small animal moving near a bollard could trigger the light, or a person passing briefly may not need the light to stay on for an extended period. Therefore, other control technologies such as time-based controls or louver controls, which do not depend on motion, are more appropriate in these contexts.
Time-based controls operate according to a pre-set schedule, turning lights on or off at designated times, which can be particularly efficient for lighting in common areas mentioned in Box 20.2. The design and operation of lighting systems, including the choice of a light board and dimming capacity, are crucial for professional settings such as theatre production. The sophistication of the system, whether it is a computer-based or analog board, impacts the execution of the lighting design and a lighting designer must consider this factor as well as the energy and resource costs mentioned in the context of large common spaces.
