RISImmersion Cooling of Suspended and Coated NanoPhosphor Particles for Extending the Limits of Optical Extraction of Light Emitting Diodes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: GaN LEDs are usually encapsulated with a cured phosphorepoxy mixture for the light conversions from blue to white light. However, during this conversion, significant selfheating problems may occur due to insufficient cooling ...
Natural Convection Immersion Cooling With Enhanced Optical Performance of Light Emitting Diode Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electronics driven at high currents may experience local hot spots, which may cause thermal degradation or even catastrophic failures. This common problem occurs at lightemitting diode (LED) chips and it is not easily ...
Thermal Performance of a Light Emitting Diode Light Engine for a Multipurpose Automotive Exterior Lighting System With Competing Board Technologies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, light emitting diodes (LEDs) have become an attractive technology for general and automotive illumination systems replacing old-fashioned incandescent and halogen systems. LEDs are preferable for automobile ...
Thermal Performance Investigation of Vapor Chamber Under Partial Heating and Different Heat Flux Conditions: Effects of Inclination Angle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The need for cooling technologies increases tremendously with raising demand on the powerful and compact electronics. There, it pushes the research and technology to the new investigations on varying heat transfer mechanisms ...
