Abstract: A cap lamp features a housing. A control module is positioned within the housing and includes a multi-function switch, a circuit board and contacts adapted to receive power from a battery. An optic module is also positioned within the housing and in engagement with the control module. The optic module includes a light emitting diode (LED) module and an integrated reflector and heat sink as well as an insulator. A bezel is fastened to the housing so as to secure the control module and optic module within the cap lamp housing. A pushbutton is positioned on the housing and is connected to the multi-function switch. A backup LED is in communication with the multi-function switch so that the main LED light or the backup LED may alternatively be selected.

Abstract: A high-voltage electrochemical-electrolytic capacitor. The capacitor includes a cathode comprising a plurality of electrically-conductive particles in intimate electrical contact with one another and disposed in a proton-conductive, electrically-non-conductive, solid ionomer matrix. The capacitor also includes an anode comprising a plurality of electrically-conductive particles in intimate electrical contact with one another and disposed in a proton-conductive, electrically-non-conductive solid ionomer matrix, the electrically-conductive particles of the anode differing in composition from the electrically-conductive particles of said cathode. The capacitor further includes a proton-conducting dielectric positioned between and in contact with each of the cathode and the anode, the proton-conducting dielectric comprising a solid ionomer.
