A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

An improved LED lighting system is provided for overhead ceiling lighting, as well as for other uses. The LED lighting system comprises elongated linear lamps having an LED luminary as a source of illumination and configured to operate as a node of an automated networked lighting system. The linear LED lamps include an interface connector operable to connect to a data network to receive control data and power signals from an external device connected to the network for use in powering LED emitters and controlling one or more operational characteristics of the linear LED lamps. The system includes support connector assemblies for securing the linear LED lamps to a channel member of an overhead dropped ceiling grid.

In some embodiments, a configurable lighting device, connectors, controllers, and methods for layout detection are provided. The configurable lighting devices, suitably connected, form an assembly of configurable lighting devices that can be removably connected with one another and re-arranged. Connectors are provided that form mechanical and electrical connections between configurable lighting devices such that a flow of electricity and control signals may be propagated without the need for direct connection between every configurable lighting device and a controller. The controller or devices connected to the controller are configured to perform layout detection such that pleasing visualizations may be rendered across the assembly that are rendered using at least the detected layout. When the configuration of the configurable lighting devices changes, the layout detection is automatically updated.

Light emitting diodes are disclosed that utilize multiple conversion materials in the conversion process in order to achieve the desired emission color point. Different embodiments of the present invention can comprise different phosphor types in separate layers on, above or around one or a plurality of LED chips to achieve the desired light conversion. The LEDs can then emit a desired combination of light from the LED chips and conversion material. In some embodiments, conversion materials can be applied as layers of different phosphor types in order of longest emission wavelength phosphor first, followed by shorter emission phosphors in sequence as opposed to applying in a homogeneously mixed phosphor converter. The conversion material layers can be applied as a blanket over the LED chips and the area surrounding the chip, such as the surface of a submount holding the LED chips.

A robust and easy to install obstruction illuminator is herein disclosed. The obstruction illuminator features an elongated body with a first end and a second end opposing the first end. The body of the obstruction illuminator has an inner cavity, which extends between the first and second end. An artificial light source is fitted to the first end of the body and an emission lens is fitted to the second end of the body. The artificial light source is configured to emit light into the cavity towards the second end. An optical condenser element is provided into the inner cavity of the body between the artificial light source and the emission lens. The optical condenser element receives light from the artificial light source as well as condenses and directs the condensed light toward the emission lens. The emission lens refracts the light into a pattern suitable for warning about the presence of an obstacle.

A stage light with an additional visual effect includes a main light source and a lampshade, the main light source being located at a bottom of the lampshade. The stage light further includes at least one effect light source and at least one light-transmitting plate located at a light outlet of the lampshade. The effect light source and the main light source are controlled independently of each other. The light-transmitting plate has a first surface and a second surface, and a first side and a second side connecting to the first surface and the second surface, respectively. At least part of the light emitted by the effect light source enters from the first side and exits from the second side. The light emitting by the effect light source exits from the second side, so that the second side is illuminated, which decorates the stage light itself.

A lighting apparatus includes a light passing cover, a rim structure and a pressing structure. The light passing cover has a peripheral edge, a central part and a reverse curve surface. The reverse curve surface is extended from the peripheral edge. The central part allowing a light source to emit a light to pass through. The rim structure has a socket, a peripheral wall, and a bottom edge. The pressing structure is made of an elastic strip bent to form a top portion, a middle portion and a root portion. The root portion is kept in the socket. The middle portion presses the reverse curve surface of the light passing cover with an elastic force of the elastic strip to keep the light passing cover staying between the middle portion and the bottom edge of the rim structure.

A lighting system includes a first light emitter configured to emit light outside a visible-light spectrum. A second light emitter is configured to emit light in a visible-light spectrum. The first and second light emitters are co-located, such as in a stacked arrangement with one light emitted atop the other. The amount of visible illumination of the second light emitter may correspond to a correlated radiant intensity of infrared light emitted by the first light emitter.

The broad view headlamp includes a plurality of light sources that illuminate an area in front of the headlamp, an area adjacent to each side of the headlamp, and an area below the headlamp. The headlamp includes a number of lighting modes, such that any one of the light sources can be operated individually or in combination with any one or more of the remaining light sources. The headlamp housing has multiple lighting compartments, each having one or more light sources disposed therein. Each compartment includes an optical lens. The various light sources, together with the optical lenses, allow the headlamp to illuminate a view area extending to, at least, the outer boundaries of the far peripheral vision of the human eye, i.e., 110 degrees to the right and left of center. Thus, the total combined view area illuminated by the headlamp is at least 220 degrees.

The customizable item sorting system is configured to guide a sorter to sort items to match specific orders for a shipper to ship. The system includes sorter light boxes to be customizably positioned at a respective shelf, and each configured to be coupled in a chain of sorter light boxes. A plurality of shipper light boxes are each configured to be coupled to a respective sorter light box and also positioned at the respective shelf. A hub is coupled to a first sorter light box in the chain and operates as a concentrator of control signals and power for the plurality of sorter light boxes in the chain. A power supply is configured to be coupled to the hub and supply power to the sorter light boxes and shipper light boxes. A controller is configured to be coupled to the hub and generate the control signals for the sorter light boxes in the chain of sorter light boxes based upon commands received via an externally coupled network, and a repeater is configured to be coupled within the chain to push power along the chain.
