A portable lighting apparatus includes a handle, a light head pivotally coupled to the handle through a plurality of positions via a joint, a battery receptacle supported by the handle, a first light source supported in the light head, a second light source supported in the light head, and a user interface supported by the handle and configured to be selectively actuated by a user to operate the first light source and the second light source. The battery receptacle is configured to receive a rechargeable battery. The first light source includes a laser selectively operable to emit a single light wavelength, and the second light source includes one or more LEDs selectively operable to emit a distribution of light wavelengths.

Some embodiments of the disclosure provide for a lighting system including a substrate. The lighting system includes several blue light emitting diodes (LEDs) supported by the substrate. The lighting system includes at least one red LED supported by the substrate. The lighting system includes a light conversion material covering the blue LEDs and the at least one red LED.

A utility light mountable to a workpiece including a main body having a first end, a second end opposite the first end, and a length extending between the first end and the second end. A light assembly is coupled to the main body and has a light housing and a light source disposed within the light housing. The light housing is pivotable and rotatable relative to the main body. The utility light further includes a battery support portion configured to selectively receive a battery. The battery support portion disposed at the first end of the main body. A handle assembly is coupled to the second end of the main body. The handle assembly has a first member configured to be grasped for carrying and maneuvering the utility light and a second member that is moveable relative to the first member.

The present application discloses a surgical lamp. The surgical lamp includes a light source, a housing, and a heat sink into which heat from the light source is transferred. The housing includes a thermal insulating shell substantially surrounding the heat sink, and a plurality of ports that enable to airflow to dissipate the heat transferred to the heat sink.

A double walled illuminated vessel for displaying indicia comprising an outer sleeve, an inner liner, a lens, a transparent or translucent connection ring, a base and an illumination module adapted to be inserted into the base whereby the base and connection ring are connected to each other creating a base illumination unit. Light from the illumination module passes through the hollow space between the outer sleeve and the inner liner such that the lens bearing indicia is illuminated thus prominently displaying any desired graphic, logo, design, trademark, symbol, letter, number or any other indicia. The connection ring transmits and diffuses light through the inner liner and upper rim as well as the sidewall of the connection ring. The base illumination unit is removable from the outer sleeve and can be used as an independent light source by a user. Additionally, the illumination module is rechargeable in one embodiment and can provide an adequate charge to a mobile device. Further embodiments provided for a removable lens or lens unit.

A photovoltaic renewable energy system utilizes a light source and one or more reflectors to produce power via photovoltaic cells. An exemplary photovoltaic renewable energy system utilizes a light source, such as Light Emitting Diodes (LED), to provide light to photovoltaic cells that therein produce electrical power. The photovoltaic cells may be arranged in a photovoltaic array to ensure maximum power conversion from the incident light. A reflector, such as a prism may be used to direct light from the light source onto the photovoltaic cells. A cell reflector, which may also be a prism, may be configured proximal to the photovoltaic cell surfaces to reflect light onto the photovoltaic surface to increase power conversion.

A clamping lamp for clamping a monitor comprises a first light source and a clamping body including a second light source, a first clamping component including a first clamping portion and a lamp connection portion, and a second clamping component including a second clamping portion. The lamp connection portion connects with the first clamping portion and the first light source. The first clamping portion leans against a front surface of the monitor and the second clamping portion leans against a back surface of the monitor when the clamping lamp clamps the monitor so the first light source is located above a top surface of the monitor. The first light source emits light toward a first zone that the front surface faces toward. The second light source emits light toward a second zone that the back surface faces toward.

A lighting device is disclosed operating a vivid source having a first duty cycle and a dulling source with second duty cycle. The vivid source and the dulling source operate at alternating time intervals where the intensity of one wavelength segment or block is emphasized in the vivid source and absent or de-emphasized in the dulling source. The operation provides the user with an emphasis on objects that reflect or absorb the emphasized wavelength segment.

A portable device for generating and providing electricity is disclosed. The device includes one or more flat solar panels; one or more batteries arranged to be changed with electric power from the one or more flat solar panels; one or more lights arranged to be powered from the one or more batteries; one or more electric connectors arranged to receive electric power form the one or more batteries and to connect to combined power/data connections on portable electronic devices; and an expandable and collapsible housing holding the solar panels, batteries, and lights, and arranged to form a hollow inner volume when expanded and a flat panel when contracted.
