In this thesis, a LED MR16 lamp that meets the requirements of IES-LM-79-08 Electrical and Photometric Measurements of Solid-State Lighting Products is designed and implemented. The proposed LED lamp consists of a LED module driving circuit and a heat sink. The LED modules selected for MR16 lamp can meet the requirements of IES-LM80-08 Measuring Lumen Maintenance of LED Light Sources. The first-order optical simulation conducted with TracePro® was done by using the optical specifications provide by CREE LED to verify the optical characteristics of the LEDs. The second-order optical lenses are designed according to the first-order optical properties of LEDs. The heat sink is designed and the thermal simulation analysis is also conducted. Finally, a 3.6W LED MR16 lamp with the luminous efficiency of 88 lm/W, color rendering index of 83.5, and the view angle of 36.5degrees is implemented. Experimental results show that the proposed lamp meets the requirements of the standards and can be used to replace the traditional 20W MR16 halogen bulb. Furthermore, the proposed LED lamps can save up to 82% of the electricity compared to the traditional halogen bulbs.
