25 DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF T~E
INVENTION
Referring to Figure 1, a ventilation louver 1 is located on the top 2 allowing for the escape of heated air generated during the operation of the lamp. The top 2 is made from an injection moulded ~O~ ;;703 blacl~ polypropylene material filled with carbon black. This forms a top surface capable of conducting a capacitive charge and forms the actuator of the touch-activated switch 11. The upper reflector 3 is located on the underside of the top. It is constructed i~rom a white polypropylene material with a matte finish. This has the effect of reflecting light back into the lamp. The clamping device 4 extends downwards from underside of the top 2 through the upper reflector 3. The clamping device includes conducting, concentric prongs 15 tied together by an O-ring S which provides the necessary clamping 10 force. The clamping device 4 is secured to a rod-like member 7 making the top 2 difficult to remove by small children. The rod-like member 7 has a rough surface to assist ~he clamping device 4 in securing the top 2 to the lamp. A rough surface is obtained by a zinc-like plating on the rod-like member 7. The rod-like member 7 l ~ is contained in a translucent cylindrical plastic body 6 integrally press fitted with the base 14 at seal 1รป. The body 6 allows for the mounting of a removeable image. The rod-like member 7 connects to ~ touch-activated switch 11 located in the base 14. The base 14 is constructed from a black plastic material with a lower reflec~or 9 O made from a white polypropylene material with a matte finish.
Additionally, ventilation apertures 16 are located in the base 14 for the free flow of air through the lamp. The base 14 also contains a light bulb socket 17 that retains only smaller sized light bulbs. This limits the power output of the lamp to a range that is acceptable with 2 5 respect to the construction of the lamp. The light bulb socket 17 and the touch-activated switch 11 are supported by a support 1 3 located within the base 14. Also within the base 14 is a cord restraint 12 that clamps the power cord to the base 14 when the rod-like member 7 is tightened into screw recess 8.
Referring to figure 2, the top 2 comprised of a louver 1having two apertures 18 and l 8' that allow for the escape of the heated air generated by the lamp during its operation.
Referring to figure 3, the lower reflector 9 is a truncated ~S conical structure with ventilation apertures 19 and 19' allowing for the free flow of air through the lamp. Alignment member 21 aligns screw recess 20 with the corresponding screw recess on the base 14 as best shown in figure 1.
Referring to figure 4, a hand 22 is shown touching the top 10 2. This has the effect of actuating the touch-activated switch 11, best shown in figure 1, causing the lamp to be activated. The light generated by the lamp causes the image 23 to appear illuminated thereby creating a decorative effect. The touch-activated switch 11 has a four-step cycle (low, medium, maximum, off) for controlling the 1~ operation of the lamp.
According to yet another aspect of the invention, the connecting means engages a power cord restraint to fix the power cord in place when the connecting means is secured within the lamp.
In one embodiment of the invention, the display means is a translucent picture or illustration preferably placed on a flexible translucent heat resistant planar sheet.
According to yet another aspect of the invention, the top and base may be provided with apertures to allow free air flow through the body of the lamp thereby safely dispersing the excess heat generated by the light bulb.
