The present invention will be described by way of exemplary embodiments, but not limitations, illustrated in the accompanying drawings in which like references denote similar elements, and in which:
Various aspects of the system and method of the present invention will be described, and for purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without these specific details. Furthermore, well known features have been omitted or simplified in order to prevent obscuring the present invention.
For example, turning now to
Referring to
In a preferred embodiment, inner support tube body 222 is disposed within the hollow tube body 220 for supporting the light emitting diode package 224, and a wider bottom portion 226 extends from the inner support tube body 222. In this case, the hollow tube body 220 can be securely inserted into the wider bottom portion 226 in a detachable form.
Next, referring to
The first LED chip 224a is typically and preferably located along the longitudinal axis C1 of the hollow tube body 220 since its emitting light property is narrow band-width centered at a red light wavelength such as in a range of about 630 nm to about 660 nm, preferably about 652 nm, suitable for rhinitis treatment. On the other hand, the second LED chip 224b with infrared light wavelength is typically and preferably located a predetermined distance away from the longitudinal axis C1 thereof, namely more near the sidewall of the hollow tube body 220 for easily heating. The infrared light wavelength is typically in a range of about 920 nm to about 960 nm, preferably about 940 nm.
In a most preferred embodiment, the light emitting diode package 224 that can be powered and controlled, via wires 16, by the control unit 12, may further comprise a first mount lead 225 for mounting the first LED chip 224a; and a second mount lead 223 disposed slightly away from the first mount lead 225, for mounting the second LED chip 224b. In one example, the first mount lead 225 and the second mount lead 223 respectively electrically connect the wires 16.
Typically, the first mount lead 225 may comprise a cup 225a for accommodating the first LED chip 224a and a lead 225b for supporting the cup 225a. And the preferred second mount lead 223 may comprise an end surface for mounting the second LED chip 224b thereon. Specifically, the end surface thereof is higher than the cup 225a of the first mount lead 225.
In view of the above, the use of LED chips disposed at different plane in a single LED package may allow the hollow tube body to be dimensioned and configured to permit insertion into a nostril of a treatment subject, since the occupied cross-section area is thus decreased. Additionally, the second LED chip 224b can be located more near the sidewall of the hollow tube body for easily heating. Hence, a patient could feel comfortable when the hollow tube body touching the internal surface of his nostril such as a rhinitis-afflicted region is warmer.
While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
