lighting system, said self-supporting stand being formed from a rim
enveloping said second part, said rim having a pre-defined thickness
sufficient to hold the weight of said lighting system, said rim swivels,
using a second swiveling mechanism from its original position of
enveloping said second part till it reaches said first part at its operative
posterior side;
d. actuating mechanism adapted to actuate said illuminating means when
the first part swivels away from said second part in order to form a linear
(co-planar) dual-part flipped-open configuration; and
e. recharging mechanism adapted to be fitted onto said second swiveling

mechanism so that its swiveling action helps in charging said lighting system.
Typically, said second part is adapted to house electronic components in order to power and drive said illuminating means.
Typically, said self-support stand includes holding means to hold self-supporting stand in its various operating positions so as to position said lighting system in accordance with various steps in the range of angular motion due to the swiveling of said rim.
Typically,. said second swiveling mechanism is co-axial with said first swiveling mechanism.
Preferably, said first swiveling means and said second swiveling means are same.
Typically, said actuating mechanism is adapted to switch off said illuminating means when the first part swivels towards said second part in a manner such that said two inner parts face and touch each other.

Typically, said actuating mechanism actuates after a certain degree of swiveling of said first part with respect to said second part is achieved.
Typically, said lighting system includes wireless plug-in which mates with a standard plug hole for charging.
Preferably, said lighting system includes a plug-in, for charging, fitted in a recess on the posterior side of said second part, and on a rotatable shaft so as that the plug-in flushes with the second part, thereby providing a flat surface.
Typically, said recharging mechanism includes a set of spring loaded wedges which convert the rotary motion of said self-supporting stand to linear motion which further applies pressure on to piezoelectric transducers which convert the mechanical force into electrical energy due to application of pressure.
Typically, said recharging mechanism includes a PCB installed in said second part in order to use the electrical energy to charge said batteries.
Preferably, said self-supporting stand is designed such that the rim can be used to hang the system on any such hook adapted to hang said lighting system.

Figure 4 illustrates a back view of said lighting system. Figure 5 illustrates a hanging side view of said lighting system.
In accordance with an embodiment of this invention, there is provided a dual-part body lighting system with a first swiveling mechanism (10) attaching a first pail (12) of the dual-part with a second part (14) of the dual-part, each of said body parts each having an inner mating surface (16, 18), with said inner mating surfaces adapted to face each other in its flip-closed condition, due to said swiveling mechanism.
In accordance with another embodiment of this invention, there is provided an illuminating means (20) installed on an inner operative mating surface of said first inner mating surface.
Typically, said second part is adapted to house electronic components in order to power and drive said illuminating means.

In accordance with yet another embodiment of this invention, there is provided a self-supporting stand (22) for supporting flip-open configuration of said lighting system, said self-supporting stand being formed from a rim enveloping said second part, said rim having a pre-defined thickness sufficient to hold the weight of said lighting system. Typically, said rim swivels, using a second swiveling mechanism (24) from its original position of enveloping said second part till it reaches said first part at its operative posterior side. The self-support stand includes holding means to hold self-supporting stand in its various operating positions so as to position said lighting system in accordance with various steps in the range of angular motion due to the swiveling of said rim.
Typically, said second swiveling mechanism is co-axial with said first swiveling mechanism.
