At least one of a selected animation an image and a character are displayed by vertical oscillation of a hand at a horizontal position of a light display device. In the horizontal position of the hand and also in the horizontal position of the light display device, a slider animation (directional arrow) is displayed without oscillation. When the light display device is upright, the device illuminates a red warning light on both sides. An illuminating device is switched on to display at least one of text, animation and a character by means of horizontal oscillation. When the light display device is caught from the right hand to the left, the displayed text, animation or character is automatically rotated to a readable position. When the device is lowered to the vertical position, the display is automatically interrupted.

Provided are an electric device and an electric device system. The electric device is provided with a battery pack attachment part, main LEDs, and a sub-LED. The main LEDs are lit by electric power from a battery pack. The sub-LED illuminates the battery pack attached to the battery pack attachment part or the battery pack attachment part. The sub-LED is lit when the voltage or capacity of the battery pack is below a predetermined value. The sub-LED is lit by electric power from a power supply part different from the battery pack.

A lighting system includes a lighting device arranged to attach to a vehicle. The lighting device includes at least two ultraviolet lights and at least one sensor. The sensor determines whether any of at least two areas or zones adjacent to the lighting device are poorly visibly illuminated and/or occupied by personnel, and illuminates these areas or zones with ultraviolet light. The lighting system is configured to operate in conjunction with existing emergency visible lighting and/or flashing visible light systems by using the sensors to sense visible illumination of each individual area or zone provided by the existing emergency visible lighting and flashing visible light systems. The lighting system may be configured to synchronize the illumination of each individual area or zone in ultraviolet light with intermittent absence of visible light illumination in each area or zone from the existing emergency visible lighting and flashing visible light systems.

The disclosure includes a convertible light device comprising a device housing, a battery pack removably coupled to the housing, and an elongate flexible light source detachably coupled to the device housing and electrically coupled to the battery pack, where the elongate flexible light source comprises a plurality of LEDs. In some embodiments, the convertible light device is configured to convert between a rope mode and a lantern mode. In the rope mode, the elongate flexible light source may be configured to extend from the device housing. In the lantern mode, the elongate flexible light source may be configured to wrap around the device housing.

A lighting device includes a housing, a power supply, a first light source such as a LED, a variable focus lens adapted to vary the focus of light from the first light source, a switch and a controller having circuitry, The circuitry is adapted to control the current to the first light source based upon a voltage of the power supply, and is adapted to control variability of the variable focus lens.

A light-emitting system (1000) removably attachable to headgear is provided, which comprises: a form factor (1010) configured to surround a portion of the headgear when the light-emitting system (1000) is removably attached to the headgear for use; a plurality of halo lighting elements (1100) configured to selectively generate at least a partial halo of light that radiates outwardly away from the light-emitting system; and at least one task lighting element (1120) aligned in a direction along a task light axis (1130) that is fixed and oriented downwardly at an oblique angle (α) relative to a transverse plane (TP) of the light-emitting system (1000), the at least one task lighting element (1120) being configured to selectively generate flood task lighting in an area in front of a user.

A light assembly includes a base, and a first light source supported by the base. The first light source includes a first light emitting diode configured to emit light in a first direction from the base. The light assembly additionally includes a second light source supported by the base, the second light source including a plurality of second light emitting diodes configured to emit light in a second direction from the base. The second light source is obliquely oriented relative to the base. The light assembly additionally includes a diffuser supported by the base, the diffuser extending upwardly from the base to enclose the first light source. The diffuser diffuses light emitted from the first light source to the surrounding area in an upward and outward direction.
