Phototherapy apparatus

1 . A phototherapy apparatus, comprising:

a) a housing adapted to permit an ergonomic holding of the apparatus, a receiving chamber being formed within the housing;

b) a radiation head mounted on the housing, the radiation head having a translucent cap; and

c) a plurality of light-emitting diodes electrically coupled to a circuit board, the circuit board being positioned within the radiation head to enable the radiation of the light-emitting diodes in direction to the translucent cap;

wherein the radiation head and the translucent cap are formed in a non-circular contour, and the light-emitting diodes are divided into at least two groups having different wavelength, and two groups of the light-emitting diodes are arranged in a staggered manner on the circuit board;

wherein an light-emitting diode (LED) control circuit is disposed within the receiving chamber to supply power to the circuit board and to enable the light-emitting action of one group of the light-emitting diodes on the circuit board; and

wherein an control panel is mounted on the surface of the housing and permits a free choice of the groups of the light-emitting diodes for a phototherapy.

2 . The phototherapy apparatus as recited in claim 1 wherein the light-emitting diode is packaged by translucent colloid and electrically coupled to the circuit board via connecting feet.

3 . The phototherapy apparatus as recited in claim 1 wherein the light-emitting diode in the form of an LED die is stuck to a recess formed on the surface of the circuit board, and the LED die is then wire-bonded to the circuit board und packaged by translucent colloid in place.

4 . The phototherapy apparatus as recited in claim 1 wherein a plurality of cooing ribs is formed at a bottom end of the circuit board.

5 . The phototherapy apparatus as recited in claim 1 wherein the LED control circuit includes:

a) a DC power supply adapted to supply DC power to the light-emitting diodes on the circuit board;

b) a plurality of LED drivers interposed between the DC power supply and the circuit board to put one group of the light-emitting diodes in operation, respectively; and

c) a controller coupled to an control panel and adapted to control the LED drivers to activate the light-emitting diodes, respectively.

6 . The phototherapy apparatus as recited in claim 5 wherein the DC power is created by an exchange power source that converts an alternating current into 1.5 V-4.5V direct current.

7 . The phototherapy apparatus as recited in claim 5 wherein the DC power may be supplied by a battery within the housing.

8 . The phototherapy apparatus as recited in claim 5 wherein a temperature detector is interposed between the controller of the LED control circuit and the circuit board for monitoring the temperature of the light-emitting diodes when they light up.

9 . The phototherapy apparatus as recited in claim 5 wherein an anion generator is coupled to the controller.

10 . A phototherapy apparatus, comprising:

a) a housing adapted to permit an ergonomic holding of the apparatus, a receiving chamber being formed within the housing;

b) a radiation head mounted on the housing, the radiation head having a translucent cap; and

c) a plurality of light-emitting diodes electrically coupled to a circuit board, the circuit board being positioned within the radiation head to enable the radiation of the light-emitting diodes in direction to the translucent cap;

wherein the radiation head and the translucent cap are formed in a non-circular contour, and the light-emitting diodes are divided into at least two groups having different wavelength, and two groups of the light-emitting diodes are arranged in a staggered manner on the circuit board;

wherein a light-emitting diode (LED) control circuit is disposed within the receiving chamber to supply power to the circuit board and to enable the light-emitting action of one group of the light-emitting diodes on the circuit board;

wherein an control panel is mounted on the surface of the housing and permits a free choice of the groups of the light-emitting diodes for a phototherapy; and

wherein a light cone is attached with a mounting portion thereof onto the radiation head, and the light cone is tapered from the mounting portion to a light exit, and the light exit corresponds to the human nose in size.

11 . The phototherapy apparatus as recited in claim 10 wherein the inner wall of the light cone is constructed as a reflector.
