1. A phototherapy device for reducing acne and acne scars on a skin surface, comprising:
a housing including a body portion with a bottom surface and a top surface; the body portion encasing:
a switch, the switch aligned centrally in the top surface of the housing,
a battery having a cylindrical shape including a circular top side, a circular bottom side, and a curved side with a height less than a diameter of the circular sides,
a computer,
a light emitter configured and aligned centrally in the housing to emit light through an aperture on the bottom surface, and
a conductor for providing electrical communication between the switch and the computer, the battery and light emitter aligned with a targeted area of the skin surface;
an attachment portion defined by an adhesive pad configured between a circumference of the bottom surface and the skin surface, the adhesive pad configured to permit light passage through the bottom surface of the housing to the underlying skin, and to retain the housing to the skin surface for bathing the targeted area of the skin with light from the light emitter, the light configured to have therapeutic effects,
the adhesive pad adapted for application onto the targeted area with a topical treatment including therapeutic agents, the topical treatment aligned with the light for synergistic effects; and
a circuit board including:
the computer,
a connection to the switch, and
a battery cage extending over the circular top side of the battery for holding the battery, the connection to the switch defined by the conductor and extending from the circuit board and flexibly to the switch aligned with the top surface of the housing and operable by manual compression, the switch disposed on the battery cage for closing an electrical circuit between the light emitter and the circuit board, the light emitter disposed on an opposed side of the circuit board from the battery and directed towards the aperture in the bottom surface of the housing;
the battery cage having a top surface extending across a diameter of the top circular side of the battery and extending parallel to the circuit board and having at least one leg extending perpendicularly from the circuit board to the top surface and flanking the curved side of the battery,
the circular bottom side of the battery disposed on the circuit board, and the circular top side of the battery facing the top surface of the battery cage,
the battery cage securing the battery in contact with the circuit board, the top surface of the battery cage disposed between the switch and the battery, and
the at least one leg defining a gap at least as wide as the height of the curved side for accommodating the battery between the top surface of the battery cage and the circuit board while the top and bottom circular sides of the battery remain parallel to the circuit board and parallel to the top surface of the battery cage;
the conductor flexibly extending from the circuit board around the top surface of the battery cage and connecting with the switch on top of the battery cage for closing the circuit at the switch in response to activation;
the switch accessible for closing the circuit through the top surface of the housing for electrical communication between the battery and the light emitter aligned with the topical treatment for direct irradiation of the targeted area of the skin through the adhesive pad.
