A switch for a light may comprise: an electrical switch actuatable in a direction transverse to the electrical switch; a switch actuator including: a plunger adjacent the electrical switch movable pivotably for actuating and de-actuating the electrical switch. A flexible boot may move the plunger toward the electrical switch when the flexible boot is pressed. The electrical switch is actuated when the flexible boot is pressed toward the electrical switch or at an angle therebetween. The switch may be adjacent a reference plane surface in a light body of the light.

The present disclosure provides a novel massage gun atmosphere lamp. The massage gun atmosphere lamp includes a switch control unit, a PCB lamp control board, a sensing device, and a battery. The switch control unit is embedded onto a PCB main control board. The PCB main control board is assembled in a massage gun cavity. The PCB lamp control board is in cooperation with a lamp source, a motor, and a light-transmissive plate respectively. The sensing device is arranged in a massage gun cavity. The battery and the motor are mounted in the massage gun cavity. The PCB main control board is configured to send a level signal to the motor for rotation speed adjustment and to the PCB lamp control board for color adjustment. The lamp is convenient to use, and features high technology and smart sensing.

A portable light comprises a light body having a light source and a tail cap assembly. The tail cap assembly includes a tail cap housing and at least one actuator that is pivotably mounted to the tail cap housing spaced away from a centerline of the light, and that extends across the centerline. The actuator has an actuation feature on the opposite side of the centerline that extends for actuating an electrical switch in the light body, whereby the portable light may be actuated over a wide range of angles.

A portable light may comprise: a light body for receiving a source of electrical power; a light source for producing light when energized; and a switch assembly for selectively coupling the source of electrical power with said light source for energizing the light source to produce light. The portable light may have a light head and a pivot assembly including a pivotable joint for pivoting the light head towards and away from the light body and a rotatable joint for rotating the light head relative to the light body; and/or may have a handle assembly coupled to the light body by a handle pivot so as to be pivotable away from and toward the light body. A releasable latch assembly that retains the handle housing adjacent the light body may be provided.

A hand holdable light comprises: a light body having a forward portion, and a central or second portion; a light source proximate a forward end; and one or more switch actuators for controlling the light source. A rearward portion may have a non-circular cross-section; the actuators is/are on the forward portion; and the central or second portion may have a recess opposite the actuator. The light is holdable by a hand in several ways wherein a finger or thumb is proximate an actuator. A battery assembly comprises: a battery housing for receiving and connecting a battery; an electrical switch on a first end of the battery housing; and a pattern of electrical contacts on a second end of the battery housing, wherein ones of the electrical contacts are connected to the battery.

A portable, sterilizable light source unit for being coupled to an instrument is provided. The unit includes a sealed housing having an anodized coating and a port for receiving an end tip of a light guide of a separate instrument, a light source mounted within the sealed housing for directing light through the port, a battery mounted within the housing for powering the light source, a switch assembly mounted on the housing for controlling light output of the light source, and an O-ring in a compressed condition between the switch assembly and the housing providing a fluid-tight seal therebetween that prevents liquid intrusion into the housing during an immersion sterilization process.

A lighting device power control circuit configured to charge one or more capacitors through the pulsing of an inductor is provided. In one example, a lighting device includes a light source and a power control circuit. The power control circuit comprises an inductor, a power transistor configured to pass an operating current associated with the light source, and one or more capacitors configured to keep the power transistor turned on to pass the operating current. The one or more capacitors are configured to be periodically charged in response to a voltage spike generated across the inductor. Related methods and additional embodiments are also provided.

A tubular bodied flashlight may be used on a long-gun or firearm. To enable actuation of a tailcap button of the flashlight in an ergonomic manner, in particular without the operator needing to shift their hands from a firing position on the firearm, a mechanical apparatus may be mounted to the flashlight. The mechanical apparatus may comprise a clamp body for securing the mechanical apparatus to the flashlight and a paddle lever pivotally mounted to the clamp body. The paddle lever is rotatable from an effective position that in use, enables a user to press the paddle lever against the tailcap button to actuate the tailcap button, and a storage position located away from the tailcap button.

A flashlight or portable light source has a battery power source, a light source, a circuit powered by the battery power source which causes the light source to emit light in an on state, a switch which causes the circuit to alternate between the on state and an off state in which the light source does not emit light when the switch is actuated by a user, a controller for causing light emitted from the light source to emit at two or more modes other than the off state, and an automatic dimmer residing within the flashlight which causes light emitted from the light source to dim without any activation of the switch after a first preselected amount of time.

Various embodiments of electric lighting devices and, in particular, electric candles are described. The devices can include a flame element onto which light can be projected from a light source. Preferably, the light is projected within a focal area on the flame element. The housing of the devices can include projections that help maintain a vertical position of a circuit board within the housing.
