Patent ID: 7201764

Claim:
A handheld hair treatment device, comprising: a non-coherent light source, outputting light that at least a portion of which has an approximate wavelength of a red-light source; a power supply for supplying power to the non-coherent light source; means to expose the scalp of an individual as the non-coherent light source is moved over the individual's scalp such that the light emanating from the non-coherent light source is substantially unobstructed from coming in contact with the scalp by the individual's hair; the means to expose the scalp further comprises a first plurality of hair deflecting means, each hair deflecting means associated with the non-coherent light source and positioned such that when the device is moved across an individual's scalp, each hair deflecting means creates an open light path in the hair in front of the light from the non-coherent light source and the light from the non-coherent light source is substantially unobstructed by the individual's hair; a second plurality of hair deflecting means, at least one hair deflecting means in the second plurality of hair deflecting means associated with at least one hair deflecting means in the first plurality of hair deflecting means such that they form a related pair of first and second hair deflecting means; at least one related pair of hair deflecting means are positioned such that the first hair deflecting means is positioned ahead of its associated second hair deflecting means such that when the device is moved across an individual's scalp, the first hair deflecting means creates an open light path to expose the scalp and the second hair deflecting means holds the open light path open while the non-coherent light source is moving across the individual's scalp; the non-coherent light source is comprised of a series of light emitting diodes; at least one light emitting diode is associated with an associated pair of first and second hair deflecting means, and further positioned between the first and second hair deflecting means such that when the device is combined through an individual's hair, an open light path is formed to provide an unobstructed path to the individual's scalp for light projected by the at least one light emitting diode; whereby the scalp of the individual is exposed during application of light to the scalp, and the amount of non-coherent light reaching the individual's scalp is maximized by the creation of open light paths in the individual's hair.
