BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to lamps and more particularly pertains to a 
new interchangeable lamp for providing an easily dismantable lamp. 
2. Description of the Prior Art 
The use of lamps is known in the prior art. More specifically, lamps 
heretofore devised and utilized are known to consist basically of 
familiar, expected and obvious structural configurations, notwithstanding 
the myriad of designs encompassed by the crowded prior art which have been 
developed for the fulfillment of countless objectives and requirements. 
Known prior art lamps include U.S. Pat. No. 3,961,176; U.S. Pat. No. 
5,236,160; U.S. Pat. No. 4,488,209; U.S. Pat. No. 4,772,993; U.S. Pat. No. 
4,425,610; and U.S. Pat. No. Des. 318,138. 
While these devices fulfill their respective, particular objectives and 
requirements, the aforementioned patents do not disclose a new 
interchangeable lamp. The inventive device includes a base having a 
mounting portion and a resting flange. The invention also includes 
elongate at least two tubes. The lower end of each tube is mountable to 
the mounting portion of the base. The substantially transparent lower 
portion of a housing is detachably couplable to the each of the upper ends 
of the tubes. Within the housing hollow interior is a light source mounted 
to the lower portion of the housing for providing light. 
In these respects, the interchangeable lamp according to the present 
invention substantially departs from the conventional concepts and designs 
of the prior art, and in so doing provides an apparatus primarily 
developed for the purpose of providing an easily dismantable lamp.

of the present invention and generally designated by the reference numeral 
10 will be described. 
As best illustrated in FIGS. 1 through 4, the interchangeable lamp 10 
generally comprises a base 20 having a mounting portion 22 and a resting 
flange 24. The invention also includes elongate at least two tubes 40. The 
lower end 48 of each tube 40 is mountable to the mounting portion 22 of 
the base 20. The substantially transparent lower portion 32 of a housing 
30 is detachably couplable to the each of the upper ends 45 of the tubes 
40. Within the housing hollow interior 35 is a light source 12 mounted to 
the lower portion 32 of the housing 30 for providing light. 
With reference to FIG. 2, the base has a mounting portion 22 and a resting 
flange 24 radially extending from the mounting portion 22. The resting 
flange 24 is designed for resting on a surface. Preferably, a plurality of 
spaced apart mounting spikes 26 may be downwardly extended from the 
resting flange 24 and positioned towards the outer periphery of the 
resting flange 24. The mounting spikes 26 are designed for insertion into 
a ground surface for helping stability of the lamp 10 when standing 
upright. With reference to FIG. 3, the mounting portion preferably 
includes a receiving bore 23. In this preferred embodiment, an elongate 
annular fitting sleeve 28 is inserted into the receiving bore 23. 
As illustrated in FIG. 4, the lamp 10 includes elongate cylindrical first, 
second and third tubes 41,42,43, with each tube 40 having a hollow 
interior 44 and opposite upper and lower ends 45,48. The upper end 45 of 
each the tube 40 is threaded 46 and has having an opening 47 into the 
hollow interior 44. The lower end 48 of each the tube 40 has a slot 49 
into the hollow interior 44 of the tube 40 that extends towards the upper 
end 45 of the tube 4. The lower end 48 of each the tube 40 is insertable 
into the bore of the annular fitting sleeve 28 to mount the tube 40 on the 
mounting portion 22 of the base 20. Preferably, the lower end 48 is 
insertable into the fitting sleeve 28 such that a portion of the slot 49 
of tube 40 is upwardly extended from the annular fitting sleeve 28. 
Preferably, as particularly shown in FIG. 4, the length of the first tube 
41 is longer than the lengths of the second 42 and third 43 tubes. 
Ideally, the length of the second tube 42 is about two thirds the length 
of the first tube 41 while the length of the third tube 43 is about one 
third the length of the first tube 41. 
As illustrated in FIG. 3, the housing 30 has a connecting portion 36, a 
substantially transparent lower portion 32, and an upper lamp shade 
portion 34. The upper lamp shade portion 34 is detachably mounted to the 
lower portion 32 so that together they define a housing hollow interior 
35. Within the housing hollow interior 35 is a light source 12 for 
providing light that is also mounted to the lower portion 32 of the 
housing 30. 
The connecting portion 36 of the housing 30 is downwardly extended from the 
lower portion 32 of the housing 30. The connecting portion 36 has a 
threaded bore 37 which is threadably engagable to the threads 46 on the 
upper ends 45 of each of the tubes 40 to permit detachable coupling of the 
connecting portion 36 to the upper ends 45 of each the tube 40. 
Ideally, as shown in FIG. 3, the lamp 10 includes an elongate flexible 
electrical power supply cord 14 downwardly extended from the connecting 
portion 36 of the housing 30. One end of the electrical power supply cord 
14 is electrically coupled to the light source 12 while the other end of 
the electrical power supply cord 14 has a plug portion 15 for electrical 
coupling to a power source for proving power to the light source 12. The 
electrical power supply cord 14 is extendable into the hollow interior 44 
of each the tube 40 when the upper end 45 of the tube 40 is coupled to the 
connecting portion 36 of the housing 30. This permits extension of the 
other end of the electrical power supply cord 14 through the slot 49 of 
the tube 40 so that the plug portion 15 can be plugged into an electrical 
outlet. 
As to a further discussion of the manner of usage and operation of the 
present invention, the same should be apparent from the above description. 
Accordingly, no further discussion relating to the manner of usage and 
operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to
