Thermal analysis of LED lamps for optimal driver integration

This paper studies the thermal influence of a light-emitting diode (LED) driver on a retrofit LED lamp, also reporting on a procedure for its thermal characterization and multiscale modeling. In this analysis, temperature is measured by infrared thermography and monitoring specific locations with thermocouples. Experimental results point out...

A polymer based miniature loop heat pipe with silicon substrate and temperature sensors for high brightness light-emitting diodes

Solid State Lighting (SSL) systems, powered by light-emitting diodes (LEDs), are revolutionizing the lighting industry with energy saving and enhanced performance compared to traditional light sources. However, around 70%-80% of the electric power will still be transferred to heat. As the elevated temperature negatively affects the maximum...

Solder joint reliability in solid-state lighting applications

Lighting is an advancing phenomenon both on the technology and on the market level due to the rapid development of the solid-state lighting technology. The interest in solder joint reliability has increased by the introduction of the so-called high brightness leadless type of packages. Solder joint reliability is one of the main failure modes in...

An introduction to system reliability for solid-state lighting
