Light indicator which comprises a support body to which multiple rows of LEDs and multiple lenses are fixed, each of which positioned in front of the corresponding row of LEDs, and provided with a rear surface directed towards the LEDs, and with a front surface directed in the sense opposite the aforesaid rear surface. In addition, the light indicator comprises multiple coupling bodies, each of which extended between two ends thereof, of which a rear end is engaged with the support body, and a front end is provided with a first bent portion engaged in abutment against the front surface of the corresponding lens in order to retain the latter integral with the support body itself.

The present disclosure provides an electronic device including: a casing, a main body of which is provided with a light transmitting area; an indicating structure including a light emitting component and a light guide component which are fixedly coupled; the light guide component is configured to scatter the light emitted by the light emitting component and then emit the scattered light; the indicating structure is fixedly coupled to the casing, and a light exiting surface of the indicating structure corresponds to the light transmitting area.

A power control and indicator device for coupling to an acoustic string instrument preamp is provided. The device includes a light emitting diode having an anode terminal and a cathode terminal, a switch having a first terminal and a second terminal, the switch having a closed position that closes a circuit between the first and second terminal and an open position that opens the circuit between the first and second terminal, a battery connector having a positive terminal and a negative terminal, the battery connector adapted to couple to a battery, a preamp connector having a positive terminal and a negative terminal, whereby with a battery connected to the battery connector, wherein with the switch in the closed position, the light emitting diode is powered and illuminates and the battery connector is coupled to the preamp connector, the battery provides power to the preamp connector, and wherein with the switch in the open position, the light emitting diode is not powered and does not illuminate and the battery connector is not coupled to the preamp connector and the battery does not provide power to the preamp connector.

The invention relates to a signalling device comprising a cover, a light source (22) mounted on a support circuit board (20) and a vibrating generator (25, 26) intended to emit sound waves, the cover forming an outer wall (11) that is at least partly translucent, characterized in that: the light source (22) is positioned between the vibrating generator (25, 26) and the outer wall (11); the cover comprises a connecting column (12) that passes through the support circuit board (20) and to which the vibrating generator (25, 26) is fixed.

A smart mask includes a face covering, an attachment member, one or more sensors, and a controller. The face covering is configured to cover a face area of a wearer. The attachment member is configured to attach the face covering onto the face area of the wearer. The one or more sensors comprises an air quality sensor configured to obtain first data associated with nearby air quality or a breathing pattern sensor configured to obtain second data associated with the wearer's breathing pattern. The controller is configured to process the first data associated with nearby air quality to identify a current air quality, or process the second data obtained by the breathing pattern. In response to determining that the current air quality is worse than a predetermined threshold, or identifying a particular breathing pattern, the controller is configured to generate a notification, notifying the wearer.

A reciprocating saw includes a casing, a clamping mechanism, a bracket, a first light-emitting piece, and a second light-emitting piece. The casing extends in a front-and-rear direction and forms an accommodation space. The clamping mechanism is disposed at least partially in the accommodation space and configured to clamp an operation accessory. The bracket is disposed at least partially on a front side of the clamping mechanism. The first light-emitting piece and the second light-emitting piece are disposed on a front side of the casing. The first light-emitting piece fits with the bracket and the operation accessory so that a cutting indicator line distributed in an extension direction of the operation accessory is formed. The second light-emitting piece fits with the bracket so that a cutting indicator region perpendicular to the cutting indicator line and extending in an up-and-down direction is formed.

An obstruction light is disclosed herein. The obstruction light can include a reflector having a first parabolic portion and a second parabolic portion. The obstruction light can also include a light assembly having at least one array of light sources disposed adjacent to the reflector between the first parabolic portion and the second parabolic portion.

An omnidirectional lens is disclosed of the type which captures light from virtually all angles of incidence, and also emits light in all directions. Embodiments are specifically disclosed as a two-way lens that receives light beams from all directions of the compass and directs those light beams to a photosensor. The same two-way lens acts in a “beacon mode” to produce light beams from one or more LEDs, and to emit such light beams (again) in all directions of the compass. The emitted light beams can also be used to signal various functions as visible signals to users on a jobsite.
