DETAILED DESCRIPTION
Reference is now made to FIGS. 1 and 2 illustrating a pickup truck 10 equipped with an infinitely adjustable cargo lamp 12. As illustrated, the cargo lamp 12 is mounted to the rear face of the cab 14 above the rear window 16. As illustrated in FIG. 2, in this position the cargo lamp 12 may be operated to direct a beam of light 20 onto a desired target area 22 within the bed 18 of the pickup truck 10.
Reference is now made to FIGS. 3-5 which illustrate the construction and features of the cargo lamp 12 in detail. As illustrated, the cargo lamp 12 includes a lamp housing 24 that holds a first adjustable lamp 26, a second adjustable lamp 28 and a stop light 30 positioned between the first and second adjustable lamps.
As best illustrated in FIGS. 3-5a and 5b, the cargo lamp 12 also includes a face 44 that covers the lamp housing 24. In the illustrated embodiment, the face 44 includes a clear lens 46 over the first adjustable lamp 26, a red lens 48 over the stop light 30 and a clear lens 50 over the second adjustable lamp 28.
As illustrated in FIGS. 3 and 4, the first adjustable lamp 26 includes a light source 32 and an adjustable frog eye assembly, generally designated by reference numeral 34, for directing light from the light source onto the target area 22. As should be appreciated, the light source 32 may comprise any light source suitable for the intended purpose including, but not necessarily limited to, one or more incandescent lamps, one or more light emitting diodes (LEDs), a light rope or other lighting structure. In the illustrated embodiment, the light source 32 comprises a primary PC board 32a with associated LEDs 32b to provide general cargo lighting and a secondary PC board 32c with LED 32d to provide infinitely adjustable directional lighting through the adjustable frog eye assembly 34. Note the pig tail wiring 32e providing an electrical connection between the secondary PC board 32c and the primary PC board 32a. 
The frog eye assembly 34 includes a main body 36 and a lens 38 held in the main body. The main body 36 holds the secondary PC board 32c and LED 32d associated therewith opposite the lens 38. The parabolic inner surface 42 of the main body 36 tends to collect and direct all light from the LED 32d through the lens 38.
As best illustrated in FIG. 4, the face 44 includes a mounting socket 52 for receiving and holding the frog eye assembly 34. The frog eye assembly 34 further includes a retainer ring 54 and a seal ring 56.
More specifically, the mounting socket 52 includes a rear flange 58. The frog eye assembly 34 is mounted in the mounting socket 52 by first positioning the seal ring 56 against the rear flange 58 and then inserting the main body 36 (including lens 38, PC board 32c and LED 32d) into the socket 52. The main body 36 is then secured in the socket 52 by means of the resilient retainer ring 54 which provides a snap friction fit with the face 44 of the cargo lamp 12. When properly assembled, the main body 36 may be infinitely adjusted to an angle of up to 30-35 degrees from the horizontal or central position for a full 360 degrees around (see FIGS. 5a and 5b). More specifically, an operator simply engages the portion of the main body 36 projecting from the face 44 and manipulates the main body to any desired position to direct the light coming through the lens 38 onto a desired target area 22. Here it should be appreciated that the rear of the main body 36 remains in engagement with the seal ring 56 at all times to seal the internal compartment 60 of the cargo lamp 12 from moisture intrusion. Further, the engagement with the resilient seal ring 56 provides enough frictional resistance to hold the main body 36 in any position in which the operator chooses to set the main body. Of course, the retainer ring 54 ensures that the main body 36 remains in its desired assembled position in the socket 52 at all times.
The second adjustable lamp 28 includes a structure identical to that described and shown above for the first adjustable lamp 26. Note the second light source 66 including primary PC board 66a with associated LEDs 66b to provide general cargo lighting through lens 49 and secondary PC board 66c with LED 66d to provide infinitely adjustable directional lighting through frog eye assembly 68. Also note pigtail wiring 66e connecting the two PC boards 66a and 66c. The only difference is the first adjustable lamp 26 is on one side of the stop light 30 while the second adjustable lamp 28 is on the other side.
The stop light 30 includes a stop light, including a PC board 62a with associated LEDs 62b, that is energized when an operator applies the brakes of the pickup truck 10. The light from the LEDs 62b is directed through the red lens 48 of the face 44 closing the lamp housing 24. The wall 64 of the lamp housing 24 compartmentalizes the light produced by the various light sources so that light from the LEDs 32b is strictly directed through the clear lens 46, the light from the stop light LEDs 62b is directed solely through the red lens 48 and the light from the LEDs 66b of the second adjustable lamp 28 is solely directed through the clear lens 50.
The cargo lamp 12 provides a number of unique benefits and advantages. The cargo lamp 12 provides the operator with a useful and convenient feature, allowing him to direct light onto a target area 22 to allow more effective work in low light ambient conditions. The infinite variability of the adjustable lamps 26, 28 allows the light to be directed virtually anywhere required on and above the bed 18 of the pickup truck 10. Further, this benefit and advantage is achieved in a compact and aesthetically pleasing design.
The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
