The present invention includes a vehicle light and method for use in applications experiencing vibrational loading and wide temperature variations. The light includes a solid state illumination device and a thermal compensator in thermal communication with the solid state illumination device. The thermal compensator operates to maintain the solid state illumination device above a temperature threshold. |

DETAILED DESCRIPTION The present invention relates to a light and associated method having particular use with an aircraft.
The light includes a solid state illumination device, for example, one or more light emitting diodes (LEDs), and a thermal compensator which maintains the temperature of the illumination device above a minimum threshold or in accordance with some other temperature criteria.
A substantial improvement in reliability over prior art incandescent bulbs having fragile filaments arises from the use of the solid state illumination device because the solid state illumination device is substantially rugged and performs well in environments experiencing high vibrational loading, thus substantially reducing the replacement and maintenance costs for the external light.
On the other hand, desired performance under changing temperature conditions is assured by the thermal compensator.
More particularly, the light and associated method provide illumination over a broad temperature range by providing thermal compensation for the solid state illumination device.
When the light is subjected to low temperatures, such as when the aircraft is at high altitudes, the thermal compensator provides compensation to maintain the illumination device above a predetermined threshold temperature above which the solid state illumination device may efficiently operate.
According to another aspect of the present invention, a vehicle light includes a solid state illumination device which contains a plurality of discrete illumination elements.
Each of the elements have an illumination axis and at least one of the elements has such an axis which is not parallel with some of the other illumination elements for providing a desired illumination pattern.
Consequently, the solid state illumination device may be configured in a variety of ways to provide a customized illumination pattern.
According to still another aspect of the present invention, a light unit includes a housing having a solid state illumination device carried thereby
