Benefits of LEDs for Instrument Cluster Lighting - App Brief

From Avago Technologies
 

 
LED technology provides a number of benefits over incandescent bulbs for instrument cluster lighting. For purposes of comparison, a MY92 Ford Thunderbird instrument cluster was retrofitted with 100% LED lighting. A number of measurements were made between the original incandescent bulb design and the LED prototype. A summary of the key findings is listed below: Benefits of LEDs for Instrument Cluster Lighting 1. LEDs Have Lower Power Consumption In this design, the LED instrument cluster uses 1/5 of the electrical current of the incandescent instrument cluster. 2. LEDs Have Less Heat Generation Interior thermal measurements within the instrument cluster case indicate that the LED design operates 10-15°C cooler than the incandescent design. Interior thermal measurements within the telltale cavity airspace indicate that the LED design operates 25-50°C cooler than the incandescent design.
