A desk lamp is a portable, positionable task light that is used to provide localized illumination of activities taking place on desks, tables and workstations. Task lights of this type are challenged with providing sufficient, uniformly distributed illuminance over the entire area that needs to be illuminated, while keeping from excessive luminances and high contrasts that can be visually fatiguing or become uncomfortable sources of glare. In order to create effective fields of view where there are sustained or high concentration visual tasks, localized task lighting imposes the need for desk lamps to incorporate two essential characteristics: functionality and flexibility.
The key to unlocking the full potential of LED lighting is to have LEDs and other constitutive parts all integrated into a single system. The fundamental design philosophy of today’s products is to integrate the LED source with a high capacity thermal management system, an optical system tailored to the task lighting application, and full-featured driver and control electronics. All components work in unison to deliver the intended value, which is reflected in the achievement of the required form factor as well as high photometric performance, system efficiency and reliability.
