Multifunctional LED lamp thermal management

Investigations in this work are connected with design of energy effective multifunctional lamp for interior lighting. A mechanical construction of a desk lamp is used. LEDs are chosen as light sources. Characteristics of LEDs allow creating lightweight construction which can serve as: desk lamp (light flux about 600 ÷ 700 lm); night light for baby room (light flux about 100 ÷ 200 lm) and lamp for general lighting of a living room (light flux about 1000 ÷ 1200 lm). Choice of proper LEDs is made. Investigations in thermal camera for optimization of thermal management of LEDs are aided by application of infrared camera. Proper choice of heat sink ensures low operation temperature regimes for LEDs and long life of the light equipment.
