A portable work light is disclosed that provides jobsite lighting and also operate as a security camera for the jobsite. The portable work light comprises a light fixture having one or more rotational degrees of freedom that can be actuated to adjust an orientation of the light fixture. The portable work light advantageously further comprises a camera 14, which provides security features for the jobsite during non-working hours and enables automatic adjustment of the light fixture to maintain optimal illumination of the jobsite during working hours. In this way, security at the jobsite, particularly during non-working hours, can be greatly improved using jobsite equipment that is also useful for other purposes.

Disclosed is a lighting fixture with a shroud that can be removed and repositioned on the housing of the lighting fixture. The shroud may have a first end with a first shape and a second end with a second shape that is different than the first shape. The user may reorient the shroud to face one of the two ends away from and at different elevations relative to the lens to provide different shapes to the light emitted from the fixture.

A device includes lamps and LED devices emitting ultraviolet light mounted to movable arms. In an optional embodiment, a housing for the lamps includes shutters that close to redirect light from the lamps into an air passage and open to permit the movable arms to redirect the UV light into the environment. Optionally, the shutters, arms, and lamps are controlled by a controller.

A foldable light assembly includes a first elongated component rotatably connected to a second elongated component between a use position and a folded position. A light is attached to either the first or the second elongated components. The first elongated component includes an external surface having a first portion with a first profile and a second portion with a second profile, in which the first profile has less curvature than the second profile. The second elongated component includes a first extending member and a second extending member each with an internal surface having a third portion with a third profile and a fourth portion with a fourth profile, in which the fourth profile has less curvature than the third profile. In the use position, the third profiles are contiguous with the second profile. In the folded position, the fourth profiles are contiguous with the first profile.

A large vehicle signaling system utilizing at least two signals in conjunction with the vehicle's lighting system to mirror the vehicle's brake and turn signals. The at least two signals may be attached to the rear face of the vehicle or brackets that allow them to pivot and move away from the rear face when not in use. The at least two signals should be positioned at a height of at least 80 inches from the ground so that they may be seen by a driver even if there are other vehicles between the driver and the large vehicle. When positioned in this way, the signaling system may allow for drivers of large vehicles to maneuver more safely as other drivers will be more aware of their signals.

The present invention provides a device for generating ultraviolet (UV) radiation whose wavelength is optimally tuned into the range of 240 to 290 nm, with peak wavelength in the range of 260 to 270 nm, which attains a Peak Germicidal Disinfection Effective Index of nearly 100%, superior to conventional UV lights and lamps. This device comprises a light-emitting diode (LED) matrix, a fan, an LED driver, a base and a motion sensor with programmable sensitivity and time delay. It may further comprise components for thermal protection and active air circulation. When operating, the device emits visible UVA radiation and blue light. With special considerations for user safety, the device effectively protects users from exposure to UV hazards and is safe to use. With the built-in thermal protection, this device may be used with either open or enclosed fixtures.
