DETAILED DESCRIPTION OF THE INVENTION
The above-described drawing figures illustrate the invention, a portable fishing light 10 for use on a boat 12 or other vehicle. The portable fishing light 10 includes both a UV light source 42 and a white light source 44. The portable fishing light 10 is particularly useful for night fishing because it directs UV light outwardly for illuminating fishing line, while directing white light inwardly for assisting the fisherman with tasks on the boat 12 (e.g., baiting a hook, removing a hook from a fish's mouth, etc.).
FIG. 1 is a front perspective view of the portable fishing light 10 illustrating a light wand 40 in a stowed position on a base housing 20. FIG. 2 is rear perspective view thereof, illustrating the light wand 40 in an extended position. As illustrated in FIGS. 1 and 2, a flexible control arm 50 of the portable fishing light 10 enables a light wand 40 to be removed from a base housing 20 of the portable fishing light 10, and positioned in almost any position so that the white light and UV light are both directed where desired.
As illustrated in FIGS. 1 and 2, the base housing 20 may be a generally rectangular housing having opposed top and bottom surfaces 22 and 24, opposed front and rear surfaces 26 and 28, and opposed left and right side surfaces 30 and 32. The top surface 22 may be spaced from the bottom surface 24 to receive a battery 60 (or batteries) there between. The top and bottom surfaces 22 and 24 may further include an aperture 54 there through for forming a handle 34 for carrying the portable fishing light 10. The handle 34 may be molded into the base housing 20, as illustrated, or may be formed in other ways known in the art. The base housing 20 may be constructed of a rigid, lightweight material (e.g., plastic) using methods well known in the art. Alternatively, the base housing 20 may be formed of stronger, heavier materials (e.g., aluminum, steel, etc.) if a stronger and more expensive version is desired. Those skilled in the art may devise alternative embodiments, and such alternatives should be considered within the scope of the present invention.
As illustrated in FIG. 1, the portable fishing light 10 may further include a pair of locking arms 58 extending from the base housing 20. The pair of locking arms 58 are adapted to receive the light wand 40 there between and frictionally engage the light wand 40 to hold the light wand 40 in the stowed position. The portable fishing light 10 may further include a corner groove 59 integrally molded into the base housing 20, and shaped to receive the flexible control arm 50 therein. When the light wand 40 is clamped or otherwise held between the pair of locking arms 58, the flexible control arm 50 is locked in the corner groove 59, thereby keeping the flexible control arm 50 in place and helping to protect it from damage. When the light wand 40 is removed from between the pair of locking arms 58, the flexible control arm 50 comes out of the corner groove 59, freeing the entire length of the flexible control arm 50 for use in positioning the light wand 40.
The base housing 20 includes a mounting element 36 for removably mounting the base housing 20 on the boat 12. In the embodiment of FIGS. 1 and 2, the mounting element 36 includes a suction cup (or set of suction cups). The suction cups 36 may be mounted, for example, on the bottom surface 24. In another embodiment, a second suction cup 36 (or set of suction cups) may also be attached to the left side surface 30 (or a similar surface or surfaces) to enable the base housing 20 to be removably mounted to the boat 12 in different orientations. The mounting element 36 may also utilize alternative attachment mechanisms, such as hooks and loops fasteners (e.g., Velcro®), magnets, adhesives, and/or other elements known in the art.
As illustrated in FIGS. 1 and 2, the light wand 40 is a housing adapted to hold the UV light source 42 (e.g., three UV LEDs) and the white light source 44 (e.g., two white LEDs). Obviously, many different light sources may be used to generate the UV light and/or the white light, including different numbers of LEDs, depending on the intensities of the LEDs used.
In one embodiment, the light wand 40 is a generally rectangular housing that includes opposing surfaces 46 and 48, with the UV LEDs 64 mounted on one of the surfaces, and the white LEDs 66 mounted on the other of the surfaces. The opposing sides enable the white light from the white light source 44 and the UV light from the UV light source 42 to be projected in opposing directions (e.g., 180 degrees from each other, or similarly different angles).
As illustrated in FIGS. 1 and 2, the flexible control arm 50 adjustably mounts the light wand 40 to the base housing 20 so that the light wand 40 can be adjustably positioned relative to the base housing 20. In one embodiment, the flexible control arm 50 is constructed of a pliant, bendable material and/or conduit that enables the light wand 40 to be easily bent or otherwise moved and positioned with respect to the base housing 20. The flexible control arm 50 may include a flexible conduit that can bend to a desired position and then maintain that position while upholding the light wand 40 thereupon. The flexible control arm 50 may alternatively be constructed at a plurality of ball and socket joints such as is disclosed in Lockwood, U.S. Pat. No. 5,449,206, or a similar tube such as disclosed in Price et al., U.S. Pat. No. 5,823,657, both of which are hereby incorporated by reference in full.
In the embodiment of FIGS. 1 and 2, a proximal end 52 of the flexible control arm 50 is slightly positioned through an aperture 54 of a rear surface 28 of the base housing 20, and to distal end 56 of the flexible control arm 50 is attached to the light wand 40. The base housing 20 further includes a pair of opposed, resilient locking arms 58 extending from the right side surface 32 of the base housing 20. A corner groove 59 is shaped to receive the flexible control arm 50.
As illustrated in FIG. 1, in a stowed position the light wand 40 may be clamped between the resilient locking arms 58 and the flexible control arm 50 may be received into the corner groove 59 (best illustrated in FIG. 2). In a stowed position, the portable fishing light 10 may be easily stored, and the light wand 40 and the flexible control arm 50 are held closely against and protected by the base housing 20.
As illustrated in FIG. 2, in the extended position the flexible control arm 50 is moved clear of the corner groove 59 so that the light wand 40 may be located in any position and orientation that may be desired by the user.
FIG. 3 is a block diagram of the portable fishing light 10. As illustrated in FIG. 3, the portable fishing light 10 may include a power unit 60, a battery voltage monitor 62, a UV LED driver 66 operably connected to the UV light source 42 (in this case a plurality of UV LEDs), and a white LED driver 66 operably connected to the white light source 44 (in this case a plurality of white LEDs). A power jack 80, illustrated in FIG. 2, enables the recharging of the power unit 60.
The portable fishing light 10 may further include a UV power toggle 78 and a white power toggle 76 (both also illustrated in FIG. 1). The power toggles enable the user to independently control the power to the light sources (between off, low, and high).
FIG. 4 is a block diagram of one embodiment of the power unit 60. As illustrated in FIG. 4, the power unit 60 may include a plurality of batteries 70 and a switch 72 for operably controlling the function of the portable fishing light 10. The plurality of batteries 70 may include, for example, D-sized NiM cell batteries, or any other power source found suitable by one skilled in the art. The switch 72, also illustrated in FIG. 1, may be any form of switch 72, or any similar or equivalent mechanism for controlling the operation of the portable fishing light 10. A battery power indicator light 74 (also illustrated in FIG. 1) may provide a visual indication that the portable fishing light 10 is powered on or off.
