Patent number: 8026528Abstract: Phototherapy devices for phototherapy treatment of a patient include a light emitter for emitting light received from a light source. Means may be provided for increasing the amount of power to the light source in response to a decrease in light output to maintain a substantially constant light output. The light source may be inside a housing and bonded to a heat sink attached to the back side of the housing to dissipate excess heat generated by the light source. Also the light source may comprise at least one LED that generates blue light output bands and at least one other LED that generates other color light output bands that are selectively mixed with the blue light output bands.Type: GrantFiled: December 22, 2008Date of Patent: September 27, 2011Assignee: Lumitex, Inc.Inventor: Jeffrey B.
