Lighting device including an LED chip-on-board light source and conformal lens

A lighting device comprising:

• a housing defining a recess configured to receive a light emitting circuit and defining a cavity configured to receive a battery;
• said housing including a main housing part defining the recess and a periphery of the cavity, and first and second covers mountable to the periphery of said housing to enclose the cavity;
• a circuit board containing the light emitting circuit and disposed in the recess of said main housing part, wherein the light emitting circuit includes one or more light emitting diodes mounted to said circuit board so as to be exposed when said circuit board is disposed in the recess of said main housing part;
• a battery disposed in the cavity between the first and second covers of said housing;
• a translucent or transparent conformal lens covering said circuit board disposed in the recess of said main housing part and the one or more light emitting diodes thereon, wherein said translucent or transparent conformal lens covers and secures said circuit board in the recess of said main housing part;
• and
• a switch for selectively energizing said light emitting circuit to cause said one or more light emitting diodes thereof to produce light, said switch including an electrical switch disposed in the cavity of said housing and an actuator of the electrical switch disposed in one of said first and second covers.

A lighting device comprising:

• a housing configured in a shape resembling a key having a blade and a bow, said housing defining a recess in the blade thereof configured to receive a light emitting circuit and defining a cavity in the bow thereof configured to receive a battery;
• a circuit board containing the light emitting circuit and disposed in the recess of the blade of said housing, wherein the light emitting circuit includes one or more light emitting diodes mounted to said circuit board so as to be exposed when said circuit board is disposed in the recess of the blade of said main housing part;
• a battery disposed in the cavity of the bow of said housing and coupled to said lighting circuit;
• a translucent or transparent conformal lens covering said circuit board disposed in the recess of the blade of said housing and covering the one or more light emitting diodes thereon, wherein said translucent or transparent conformal lens covers and secures said circuit board in the recess of the blade of said housing;
• and
• a switch for selectively energizing said light emitting circuit to cause said one or more light emitting diodes thereof to produce light, said switch including an electrical switch disposed in the cavity of the bow of said housing.
