Media player device with foreground illuminating flashlight

A media player device having an integrated ground-illuminating flashlight provides hands-free ground illumination while walking. The media player device includes a lanyard attached to a first end of a housing, a first lamp located at a second end of the housing for use as an ordinary flashlight, and a second lamp located on a front side of the housing and directed at an acute angle from the housing toward the second end of the housing, so that the ground in front of a wearer of the media player device is illuminated. A speaker for reproducing the audio generated by the media player device may also be located on the front of the housing to provide audibility of the playback audio, or may alternatively be located on the first end or side of the housing. Controls are provided on the front or side of the housing to provide easy access when wearing the device.

LED lamp with a brightness control device
09862303 · 2018-01-09 · ·

The present invention provides a headlamp capable of producing different light beams and fitted with a dynamic control mechanism for controlling the brightness minimizing light interference in all situations. The lamp comprises a light source with LED-type diodes; means for controlling the brightness and/or the geometry of the light beam; capturing means for generating an electrical signal representative of the reflected light intensity of the area illuminated by said light beam onto an illuminated object; and a control unit for generating control signals from the information generated by said capture system. The lamp has capturing means includes a focal system having a variable field under control of the control unit. Preferably, the capturing means includes at least two sensors with fixed focal length or, alternatively, a single sensor may be combined with a single controllable focal system electrically.

Underwater lights for divers

An LED underwater light, which can be hand-held or mounted on an underwater camera housing, is switchable between two light modes. A first embodiment of the dive light is a focus light, used for initial focusing with a still underwater camera. Incorporated in the focus light is a red light source to which the focus light can be switched from initially projected white light. The switch is used to switch off a series of white LEDs while switching on a series of red LEDs. In another embodiment, the dive light is a flood/spot light, or with another two types of selectable LED arrays, and enables a diver to quickly switch between two types of light projection. Another feature is a laser beam projecting device within the housing, with a momentary switch on the housing to power the laser, as for pointing out underwater objects of interest, the laser beam being projected to the same area as the spot beam.

A lighting system includes a top housing, a bottom housing, and lens arranged between the top housing and the bottom housing. The lens includes a plurality of side surfaces that extend between the top housing and the bottom housing to form a perimeter of the lens. A plurality of lighting elements are configured to direct an emission of light out of the plurality of side surfaces. A controller is configured to selectively energize the plurality of lighting elements based on a first signal from a GPS module.

Manhole lighting system

A portable lighting system including a ring shaped body having a top surface, a bottom surface, an outside wall and an inside wall, the ring shaped body defining a body perimeter, a rim secured to the body and extending away from the outside wall, a plurality of lights secured about the body perimeter, and a power source operatively connected to the plurality of lights. The power source may be a battery or other power source and can power the lights in addition to a controller, camera, transceiver, or sensor. One or more of the lights may be flexibly secured to the body and the body may be secured in place through a variety of ways. A safety ring and/or accessory bracket may be secured atop the portable lighting system.

Inflatable solar powered lamp
09638399 · 2017-05-02 · ·

A solar powered lamp is provided with flat ends and a flexible housing, such that the housing can be inflated to form a free standing cylinder. A solar panel faces outward on one of the flat ends for recharging a low-profile rechargeable battery which, under the control of a printed circuit panel, powers an array of LEDs, which point into the lamp housing. Reflective surfaces, facing each other on opposite inside end walls of the lamp, maximize the diffusion of light from the LEDs. The lamp is a durable, portable, long light lighting solution for those who live off the electric power grid, victims of disaster, and the like.

Lighting system

A lighting system includes a lighting device configured to connect to an object. The lighting device includes a body and a control device. One or more ultraviolet light sources are attached to the body and connected to the control device. The ultraviolet light source(s) emit ultraviolet light in a wavelength range from 10 nm to 445 nm. The control device controls the frequency and duration of strobing of the ultraviolet light source(s). The control device cooperates with nearby emergency visible lighting and/or flashing visible light systems to designate and protect gaps in time from visible light illumination from the nearby emergency visible lighting and/or flashing visible light systems. The control device synchronizes the strobing of the ultraviolet light source(s) with the absence of visible light illumination from the nearby emergency visible lighting and/or flashing visible light systems during the designated gaps in time.
