Often task lighting refers to increasing illuminance to better accomplish a specific activity. However, the illuminance level is not the only factor governing visibility. Contrast is also important, and a poorly positioned light source may cause contrast reduction, resulting in loss of visibility. The most important purpose of task lighting in the office is not increasing illuminance, but improving contrast. General lighting can be reduced because task lighting provides focused light where needed.
Adjustable task-lighting systems using liquid crystals
A computer-implemented method includes receiving, using a user interface element associated with an adjustable task-lighting module, a user input representing a selected illumination beam pattern for light emitted by the adjustable task-lighting module. The method also includes determining, based on the user input, a control voltage. Thereafter, the method includes controlling an adjustable voltage source associated with the adjustable task-lighting module to provide the determined control voltage to a configurable liquid-crystal element of the adjustable task-lighting module to configure the adjustable task-lighting module to emit light having the selected illumination beam pattern.

A Mechanic's Creeper with Lights is a mechanic's creeper equipped with integrated task lighting powered by a rechargeable battery pack. The device is provided with multiple light emitting diode (LED) lights on either side of the headrest. The lights are low profile and do not interfere with use of the creeper. The lights, held in place via magnets, are wired together to a common switch located at the top of the creeper that is easily reached when laying on the creeper. The lights are powered by a typical removable battery pack used to power portable tools such as those from DeWalt®, Milwaukee®, or the like. Various adapters to utilize different battery systems and voltages could be provided. The battery pack is located on the underside of the device near the user's head for easy access should removal of the battery for recharging be necessary.
