Abstract
A hand-held portable light emitting device is suitable for medical and industrial photocuring and phototherapy applications. The hand-held portable light emitting device has: (a) a portable housing having a front end and a rear end; (b) a semiconducting light emitter having a matrix of a plurality of light emitting diodes mounted at the front end of the housing to emit light energy suitable for initiating a photo-reaction; (c) a power supply connected to the light emitter to provide the electrical power for energizing the diodes to emit the light energy; (d) a controller connected to the light emitter and the power supply, to vary the level of the light energy; (e) a mount at the front end of the housing; and (f) an optical assembly mounted to the mount, to direct the light energy generated from the diodes to a photoreaction site near the optical assembly.
