    Abstract: A visual status indicator for an electrical apparatus is disclosed. The status indicator can be mounted within a lower cover of the electrical apparatus such that various display faces of the indicator are visible through one or more viewing windows of the lower cover. The status indicator can comprise a mounting base with protrusions and at least one wing, wherein the wing comprises at least one display face. At least one swing arm can be attached to the mounting base via the protrusions and the at least one swing arm can comprise at least one display face. The swing arm can be actuated such that either the display face on the wing or the display face on the swing arm is visible through the viewing window to indicate the status of the electrical apparatus.

    Abstract: A lighting device for illumination, data communication, and occupancy detection includes a processor and a transmitter circuit that is configured to generate a first electrical signal. During a first time duration, the first electrical signal is a carrier signal having a first frequency, and during a second time duration, the first electrical signal is a data encoded signal. The lighting device further includes a light source configured to emit a first visible light based on the first electrical signal. The lighting device also includes a receiver configured to receive a second visible light. The processor is configured to detect a motion in a monitored area based on the second visible light.

    Abstract: A lighting system includes a housing. The housing includes a light source portion, an electronic component portion, and a partition wall that is disposed between the light source portion and the electronic component portion. Further, the housing includes a channel that extends at an angle downwards from a portion of the partition wall to the light source portion. The channel provides a passageway from the electronic component portion to the light source portion of the housing. A grommet is disposed in the inclined channel to prevent external environmental elements, such as dust, water, etc., from entering the electronic component portion from the light source portion. Further, the lighting system includes a mounting bracket on which one or more electronic components associated with the lighting system are mounted. The mounting bracket is disposed within the electronic component portion and coupled to a surface of the electronic component portion.

    Abstract: A lighting device includes a light source that emits an illumination light. The light source includes a first group of light emitting diodes (LEDs) that emits a first light and a second group of LEDs that emits a second light. The first light has a first Correlated Color Temperature (CCT), and the second light causes the illumination light to have a warmer CCT. The lighting device further includes a differential amplifier to adjust a current flow through the second group of LEDs. The second light is switched on when a current provided to the light source is below a threshold corresponding to the adjustable reference voltage. The lighting device also includes a current sensor to provide a sensor output signal to a second input of the differential amplifier, the sensor output signal having a second voltage corresponding to the current provided to the light source.
