Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
         [0025]    The reference number  100  ( FIGS. 1-2 ) generally designates a convertible lamp array device embodying the present invention. In the illustrated example, the convertible lamp array device  100  comprises a spine  101 , a first side panel  102 , and a second side panel  103 , with the first side panel  102  and the second side panel  103  being rotatably attached to the spine  101 . The convertible lamp array device  100  can be used to treat human skin disease and cosmetic abnormalities (e.g., acne) using light alone or in other manners as is well known to those skilled in the art. It is also contemplated that the device  100  could be used for mood improvement, wound healing (as is well known to those skilled in the art), sun tanning, or curing various items (e.g., epoxies). In the illustrated example, the first side panel  102  and the second side panel  103  are rotatably attached to the spine  101  by four upper hinges  104  and eight spacers  106 . However, it is contemplated that any number of hinges  104  and spacers  106  could be used or that the first side panel  102  and the second side panel  103  could be rotatably attached to the spine  101  in any manner. Electrical light sources, shown in more detail in  FIGS. 11 and 12 , are located on inner surfaces of the first side panel  102 , the second side panel  103  and a bottom surface of the spine  101 . A first wing panel  107  and a second wing panel  108  are rotatably attached to the first side panel  102  and the second side panel  103 , respectively. In the illustrated example, the first wing panel  102  and the second wing panel  103  are rotatably attached to the first side panel  102  and the second side panel  103  by lower hinges  105 . Although only one hinge  105  is illustrated as connecting the first wing panel  107  and the second wing panel  108  to the first side panel  102  and the second side panel  103 , it is contemplated that any number of hinges  105  could be used or that the first wing panel  107  and the second wing panel  108  could be rotatably attached to the first side panel  102  and the second side panel  103  in any manner. It is contemplated that the spine  101 , the first side panel  102 , the second side panel  103 , the first wing panel  107  and the second wing panel  108  could be made of any material that has the strength to support the entire device  100  (e.g., plastic). The hinges  104  and  105  can have a constant torque and/or can be set at a selected rotated position and easily maintained in that position until rotated by a user of the convertible lamp array device  100 . 
         [0026]    As illustrated in  FIG. 1 , the convertible lamp array device  100  can be situated in a closed position for moving and storage. Therefore, when the convertible lamp array device  100  is not in use, the convertible lamp array device  100  can be folded up and stored (e.g., on a bookshelf, counter or desk). The convertible lamp array  100  also has a partially open position as illustrated in  FIGS. 3A ,  3 B,  4 A,  4 B,  7 A,  7 B,  8 A and  8 B for treating heads, scalps, arms, legs, hands and feet of a patient as discussed in more detail below. Furthermore, the convertible lamp array  100  includes a fully open position as illustrated in  FIGS. 5A ,  5 B,  6 A and  6 B for treating chests and backs of male and female patients. The convertible lamp array device  100  can be held in any partially or fully open position by means of a constant holding torque application mechanism contained in hinges  104  and  105 . The amount of holding torque applied can be varied by adjustment screws  204  and  205  in the hinges  104  and  105  as is well known to those skilled in the art. Air gaps  208  are created by the spacers  106  between the spine  101  and the first side panel  102  and the second side panel  103 , with the air gaps  208  providing ventilation during patient treatment.
