Thermal Design Considerations for Portable DLP™ Projectors

Overview Portable DLP™ (Digital Light Processing™) projectors continue to lead the projector industry in terms of lumens/in3 and lumens/pound. Recently announced products break the 1.4 kg (3 lb.) barrier with brightness exceeding 1000 lumens. While the weight and volume of these products has decreased dramatically over the past several years, the power dissipation has remained unchanged or, at best, decreased only slightly. Trends in projector size and power are explored and compared to other types of portable equipment such as the laptop computer. Critical thermal design considerations are discussed including DMD™ (Digital Micromirror Device™) cooling, lamp cooling, touch temperature requirements, fan selection, fan temperature, vent design, and acoustic challenges. Testing and analysis methods used in the design process for the system and subsystem levels are also discussed.
