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.
A hand-held portable light emitting device comprising: (a) a portable housing having a front end and rear end; (b) light emitting semiconducting means having a matrix of a plurality of light emitting diode means mounted at said front end, said light emitting diode means being operative to emit light
A hand-held portable light emitting device comprising: (a) a portable housing having a front end and rear end; (b) light emitting semiconducting means having a matrix of a plurality of light emitting diode means mounted at said front end, said light emitting diode means being operative to emit light energy, suitable for initiating a photo-reaction; (c) power means coupled to said semiconducting means and operative to provide the electrical power for energizing said plurality of light emitting diode means to emit said light energy; (d) control means connected to said semiconducting means and said power means, and operative to vary a level of said light energy; (e) mounting means provided at said front end of said housing; (f) an optical assembly mounted to said mounting means, said optical assembly being operative to direct said light energy generated from said light emitting diode means to a photoreaction location disposed adjacent to said optical assembly; (g) wherein said control means comprises drive means for driving said light emitting semiconductor means and a controller for controlling said drive means; (h) wherein said drive means includes pulse means for pulsing said light emitting semiconductor means to emit energy suitable for photocuring or phototherapy; and (i) wherein said pulse means comprises pulse width modulation means having an oscillator for producing a square-wave output, a sawtooth waveform generator for producing a sawtooth waveform from said square-wave output, and a pulse width modulator for producing an output control signal having a duty cycle and said duty cycle being variable in response to a control input signal generated by said controller and said drive means being responsive to said output control signal for pulsing said light emitting semiconductor means.
