Abstract
A method for making a lighting device includes: obtaining a circuit board having one or more light emitting devices; obtaining a housing configured to receive the circuit board; placing the circuit board in the housing; then dispensing a conformal coating material onto the circuit board; allowing the dispensed conformal coating material to spread and level; and curing the conformal coating material to form a cover or lens on the circuit board. A lighting device may include: a housing configured to receive a light emitting circuit and a battery; a light emitting circuit including one or more light emitting diodes mounted to a circuit board; a translucent or transparent conformal lens formed to cover the one or more light emitting diodes; and an electrical switch for selectively energizing the light emitting diodes to produce light. The housing may be in a shape resembling a key.
