USE OF LIGHT EMITTING DIODES IN AUTOMOTIVE INDICATOR AND ILLUMINATION APPLICATIONS
The efficiency of light emitting diode materials has continued to make marked improvements during the past few years. Applications which one to two years ago were considered to be outside the realm of LED's are now or will soon be a practical reality. This paper will address briefly the technological improvements in the LED materials which will soon lead to factors of 4 to 10 gains in light output. The balance of the paper will address the performance of several possible LED solutions to such industry-wide requirements as tail-lights, stoplights, courtesy lights, and mood-lighting. Particular attention will be given to work currently underway on LED implementations of the Center Mount Stop Light which has been mandated for the 1985 model year automobiles (United States) by the NHTSA. Device performance as well as advantages in the areas of size, illumination uniformity, and reliability will be discussed.
