Design and Thermal Analysis of Heat Sink for Light Emitting Diode of Street Light
Light-Emitting Diode (LED) street lamps swear heavily on prospering thermal management, that powerfully affects the optical extraction and also the reliability/durability of the LED lamp. Light Emitting Diode (LEDs) are currently wide employed in several fields together with traffic lights, vehicle backlights and liquid show (LCD) displays thanks to their long life, sensible illumination potency and low energy consumption. At present, LEDs are more and more commutation the standard lighting and are getting used normally illumination cherish the road lamp. For the dynamic LED street lamps, sensible light-weight extraction is that the most vital factor, however low junction temperature of the LED modules is additionally vital for achieving an extended period of time and a high optical potency. Actually, there are several reports concerning early failures of street lamps, known as dead lamps that are thought to be a barrier within the public and administration acceptance of LED street lamps. Thus temperature estimation is often a vital issue for LED development. During this paper we have a tendency to review completely different previous work of thermal analysis on LED and conjointly discuss concerning drawbacks and deserves of previous analysis.
