When a beverage container is fitted into a drink holder, air needs to escape out of the bottom of the drink holder due to the tight fit between the beverage container and the drink holder. On the other hand, when the beverage container is being removed from the drink holder, air is introduced back in to the drink holder to easily remove the beverage container from the drink holder. FIGS. 6A and 6B are schematic diagrams respectively illustrating a top view and a side view of an air channel that can be implemented within embodiments of the present invention. As shown in FIG. 6A, the air channel 112 includes a depressed portion 112a at a center region of the top surface 101b of the base portion 101, and a plurality of indented canal portions 112b radiating outward from the depressed portion 112a. According to an embodiment of the present invention, the depressed portion 112a may not include an adhesive material 150 thereon however as shown in FIG. 6A, all or a portion of the indented canal portions 112b may be covered with the adhesive material 150 such that any air may be removed within the canal portion 112b beneath the adhesive material 150 covering the same. A conventional drink holder typically includes a hole portion along a bottom surface thereof for releasing air. Thus, when a drink holder is connected to the illumination apparatus 100, the air may be dispersed along the line of connection there between. In this embodiment of the present invention, the attaching means 150 will be disposed along the portions of the top surface 101b which does not include the indented canal portions 112b. The present invention is not limited to any particular number of depressed portions 112a or indented canal portions 112b and may vary accordingly. The present invention is not limited to any particular type of air channel and may vary accordingly. FIGS. 7A and 7B are schematic diagrams illustrating an air channel that can be implemented within alternative embodiments of the present invention. As shown in FIGS. 7A and 7B, the air channel 112 may include at least one canal portion 113 extending through the base portion 101 to release air out of the bottom thereof or out of a side surface thereof as shown in FIG. 7B. The canal portion 113 is formed such that it circumvents the circuit board 102 to not interfere with the components thereof.
According to another embodiment of the present invention, a securing mechanism may be provided to secure the illumination apparatus and drink holder to an external surface not shown. The securing mechanism may include a plurality of magnets, suction cups, or a belt clip mechanism, for example.

The securing mechanism 160 includes at least one securing portion (e.g., a plurality of magnets 161 or other type of securing portion) sandwiched between two layer portions 162a and 162b. The first and second layer portions 162a and 162b may be formed of the same or different materials. According to one embodiment of the present invention, the first layer portion 162a is formed of a double-sided adhesive, for example, for securing the magnets 161 to the side surface of an existing drink holder 300. The first layer portion 162a includes a flexible end portion 163 for securing to the top surface 101b of the base portion 101 of the illumination apparatus 101. According to an embodiment of the present invention, the second layer portion 162b may be formed of a single-sided adhesive, cloth material or rubber material and assists with securing the magnets 161 in place while being attached to the side surface of the drink holder 300. As shown in FIG. 8B, when implemented, the first layer portion 162a is secured along the side surface of the existing drink holder 300 such that the magnets 161 are attachable to the external surface.
According to another embodiment of the present invention, a drink holder may be provided. FIG. 9 is a diagram illustrating a drink holder that can be implemented within embodiments of the present invention.
