Abstract
The goal of the study in this thesis is to develop a new LED luminaire consisting of rectangular arrangement of power LEDs for office lighting. The new luminaire has improved cooling arrangement to reduce its operating temperature. The luminaire is specified, designed, constructed and tested according to custom made measuring methods and setups. The same measurements have been carried out on a commercial luminaire having an equal output light for sake of comparison. Our design is much lighter than the commercial.Here it is proved that with careful design one can further improve the construction of the LED luminaire.
