DOCK LIGHT WITH SELF-CORRECTING BEAM
Disclosed is a dock light assembly for illuminating a trailer interior. The dock light assembly may include a cylindrical housing having an illumination source therein, and an optical lens secured to an end of the housing. The optical lens may be configured to provide focused illumination to the trailer interior. A rotationally self-correcting screen device may be positioned between the illumination source and the optical lens. The screen device may be configured to absorb a portion of the focused illumination such that illumination to an upper portion of the trailer interior is reduced. The rotationally self-correcting screen device remains in a horizontal orientation even if the housing is rotated. One benefit of the disclosed dock light assembly is that forklift operators working in the trailer interior are shielded from high intensity light, even though the lower portion of the trailer interior remains brightly lit.
Industrial lighting device
Industrial lighting device including a light source and a sealed housing containing the light source. The housing includes a support delimiting a housing window extending opposite the light source, a window pane sealing the housing window, and a sealing gasket extending along the periphery of the housing window and compressed between the window pane and the support. The device includes a filter extending in front of the housing window, outside the housing. The filter includes a frame defining a frame window which is removably fixed to the housing, in an assembled position in which the frame window is opposite the housing window, and an optical film fixed to the frame and sealing the frame window. The device includes an elastic compression member arranged between the support and the frame.
LED LIGHTING SYSTEM AND INSTALLATION METHODS
A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding MC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.
Pistol mounted light and operation thereof
A flashlight for use with a pistol, the pistol having a trigger guard and a mounting rail. The flashlight includes an elongated housing having a spring arm clamping mechanism for mounting to the mounting rail, a light source at one end thereof, and paddle switches at an opposing end.
Lighting Assembly with Spatially Arranged Light Source Array for Targeted Light Distribution
Disclosed is a lighting assembly for providing configured light distributions and illumination patterns by spatial arrangement of at least one light source array with a focal region of a light scattering primary transmissive optical element. Adjustment of light scattering properties can be used to further control light distribution patterns. Embodiments with light source arrays of linear and circular geometry are typical and one or more Fresnel lens patterns can be used to provide one or more focal regions. An optional auxiliary transmissive optical element can provide further control of light distribution and brightness uniformity for improved visual appearance. The lighting assembly can be used to provide a wide range of symmetric and asymmetric lighting distributions for direct or indirect lighting. The lighting assembly is therefore effective and easily configurable in a wide range of typical indoor and outdoor lighting applications including downlighting, spotlighting, wall washing, cove lighting, retail lighting, warehouse lighting.
Light mounting system
A light fixture, for a ceiling plenum system defining an upstream space and a downstream space, includes a light-fixture base defining a light-fixture axis. First and second side walls extend toward the downstream space and are sealingly attached to the base plate and to first and second end plates. First and second legs are sealingly attached to the light-fixture base by one of a first-leg continuously welded joint and a first-leg monolithic connection. A downstream end of each leg forms a knife portion. First and second gas filters each comprise an orthogonal gas-filter frame defining an interior perimeter and an exterior perimeter. A trough with sealant affixed therein is sealingly attached to and surrounds a portion of the exterior perimeter. A trough opening faces the downstream space, with the knife portions penetrating surfaces of the sealant, forming a seal between the light-fixture base and each gas filter.
LIGHT FIXTURE
A light fixture includes a housing having a first portion and a second portion. The light fixture further includes a first light emitting element supported within the first portion of the housing, and a second light emitting element supported within the second portion of the housing. The second light emitting element is controlled such that the second light emitting element provides a different color than the first light emitting element.
Enhanced Fixture in Grid of First Voltage With Step-Down Power Supply for Energizing Ancillary Device Requiring Second Voltage
An enhanced array of light fixtures for providing both light and a desired non-light feature within an illuminated area of a structure. The enhanced array is formed from a first plurality of light fixtures that are adapted for emitting light and a reduced plurality of enhanced light fixtures comprised of a subset of the first plurality of light fixtures that are adapted for emitting light and also for supporting a corresponding plurality of auxiliary non-light-emitting devices that require a different voltage and are adapted for providing a desired non-light feature within the illuminated area of the structure.
FLUID-COOLED LED-BASED LIGHTING METHODS AND APPARATUS FOR CONTROLLED ENVIRONMENT AGRICULTURE WITH INTEGRATED CAMERAS AND/OR SENSORS AND WIRELESS COMMUNICATIONS
A fluid-cooled LED-based lighting fixture for Controlled Environment Agriculture (CEA) to improve energy efficiency, recycle waste heat, and support the operation of environmental sensors in a controlled agricultural environment. In one example, a lighting fixture frame mechanically supports and houses respective components of the lighting fixture and includes a light spine to mechanically couple the lighting fixture to a support structure. One or more coolant pipes formed from copper and coupled to the lighting fixture frame conduct a fluid coolant through the lighting fixture to remove heat. The lighting fixture comprises one or more LED modules to emit light, one or more onboard sensors and/or cameras, wireless communication functionality, and multiple electrical power and communication ports to facilitate interconnection of the lighting fixture in a variety of controlled agricultural environments. In some examples, the lighting fixture includes a multispectral imaging system to acquire multispectral images of the environment.
LIGHTING MODULE FOR INDOOR FARMING
A lighting module for illuminating cultivated crops in indoor farming comprises at least one monolithic efficiency enhancing optical element (EEOE) further comprising: (a) a front portion comprising a spectrum conversion layer; (b) an optically transparent middle body portion having at least one light source embedded there within and configured to emit spectrally controllable radiation; and (c) a back portion configured to reflect the radiation emitted by the spectrum conversion layer to the cultivated crops. The back portion has a central area being adjacent to the optically transparent middle body portion configured for reflecting radiation propagating within the optically transparent middle body portion and a peripheral area configured for reflecting radiation emerged from the optically transparent middle body portion via the side surface.
