  • Patent number: 7997751
    Abstract: A pressure-actuated light device (1) with a holding portion (2) that allows a user to hold the pressure-actuated light device in a user's hand. The pressure-actuated light device comprises a housing (3) which houses a light emitting diode (“LED”) (6) having a cathode (11) and an anode (10) extending from it. The cathode has one end permanently connected to the LED and a second end in constant contact with a negative terminal (8) of a battery (7). The anode has one end permanently connected to the LED and a second end separated from a positive terminal (9) of the battery by a spacer (12) which prevents the anode from making contact with the positive terminal while the device is not in use. When pressure is applied to a button (4) on the housing, the button presses the anode against the positive terminal thereby creating an electrical circuit which activates the LED. The holding portion may take alternative forms, including a fin (13), clip (14), ring (15) or elastomeric loop (16).
