Abstract

A lighting module includes a first printed circuit board (PCB) with a push button switch and a charging port, a second PCB with a light emitting diode (LED), a rechargeable battery sandwiched between the PCB's, and ring disposed between the PCB's and surrounding the battery. A device including the lighting module, a body having a cavity with an aperture, and a cap having a protrusion facing the body. The lighting module received in the cavity, with the cap covering the aperture. The protrusion and push button switch are positioned such that when the cap is pushed inward near the protrusion, the protrusion pushes the push button switch and activates the lighting module. The cap further includes a ridge surrounding the protrusion on the outward side, the ridge preventing the protrusion from being pushed into the push button switch, unless the cap is pressed at approximately a location of the protrusion.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1. A lighting module, comprising:
a first printed circuit board and a second printed circuit board;
a battery sandwiched between the first printed circuit board and the second printed circuit board, the first printed circuit board and the second printed circuit board enclosing and holding the battery in place;
a side wall located between the first printed circuit board and the second printed circuit board and enclosing the battery;
a battery charging port provided in one of the first printed circuit board and the second printed circuit board;
a push button switch provided in one of the first printed circuit board of the second printed circuit board; and
an LED provided in one of the first printed circuit board of the second printed circuit board, wherein the LED and the push button switch are not on a same one of the first printed circuit board and the second printed circuit board;
a post interconnecting the first printed circuit board and the second printed circuit board;
a body having a plurality of notches; and
a plurality of teeth provided in the sidewall,
wherein the plurality of notches in the body correspond to the plurality of teeth in the sidewall to provide a friction fit of the lighting module in the body.
