A hybrid method, applied thermal modeling and temperature measurement, is proposed to
estimate the junction temperature (T j) of high-power light-emitting diodes (LEDs) at system …

The junction temperature (T j) of LEDs in an LED luminaire is useful for projecting the
luminous flux maintenance or lifetime of luminaires. Normally, a LED luminaire has a unique …

Five different types of LED lamps were aged for 35 months at room temperature and for six
months at the temperatures of 45℃ and 60℃. The lifetimes for the lamps were predicted …

The paper presents an innovative method for High Power LEDs cooling in harsh conditions.
To take full advantage of the benefits of LEDs, proper thermal management must be …

The performance and reliability of the high-power light-emitting diodes (HP LEDs) are
closely related to the quality of the die attach adhesive (DAA) layer, because voids or …
