Abstract
A fluorescent doorknob assembly for illuminating a doorknob in a darkened environment includes a doorknob that is rotatably mounted on a door for opening the door. A light emitter is coupled to the doorknob. The light emitter is comprised of a fluorescent material thereby facilitating the light emitter to emit light in a darkened environment. In this way the light emitter illuminates the doorknob thereby making the doorknob visible to a user a night.
Claims2
A fluorescent doorknob assembly being configured to make a doorknob visible in a darkened environment, said assembly comprising:
- a doorknob being rotatably mounted on a door for opening the door, said doorknob having mounting plate, a shaft extending outwardly from said mounting plate and a handle being coupled to and extending laterally away from said distal end of said shaft, said handle having an exposed surface with respect to said distal end of said shaft;
- and
- a light emitter being coupled to said doorknob, said light emitter being comprised of a fluorescent material thereby facilitating said light emitter to emit light in a darkened environment wherein said light emitter is configured to make said doorknob visible to a user at night, said light emitter having a contact surface and an emitting surface, said contact surface being continuous such that said light emitter forms a closed ring concentric with said shaft of said doorknob, said contact surface being bonded to said exposed surface of said handle having said light emitter surrounding a center of said exposed surface and having said emitting surface being exposed, said emitting surface being concavely arcuate with respect to said contact surface such that said emitting surface presents a rounded profile with an inwardly facing surface concentric with said shaft whereby said light emitter emits light directly towards a central axis of said light emitter to illuminate an area of said handle surrounded by said light emitter.
