Narrative:

On departure from bwi, the equipment cooling smoke light illuminated, followed several mins later by the equipment overheat light and associated EICAS messages. Electrical odor and increased cockpit temperature noted. We declared an emergency, notified our company, requested emergency ground equipment and diverted to dulles (iad). The cabin prepared for evacuate/evacuation. The situation improved on final. No evacuate/evacuation was accomplished. Landing was normal. All appropriate irregular and normal procedures were completed. ATC services were excellent.
