A motor vehicle includes headlamps having a plurality of LED light sources, one or more processors, and a memory storing instructions. One or more processors executing the instructions are enabled to receive first data, including at least map data, indicating a road curvature upcoming along a road on which the motor vehicle is traveling. The processors are also enabled to determine a light change, the change adapting a light pattern of the headlamps in at least one of color, intensity or spatial distribution to increase light in a direction of the road curvature ahead of the motor vehicle and shaping light based at least in part on the road curvature. The processors are further enabled to control at least a first plurality of the LED light sources to provide light based at least in part on the determined light change and prior to the motor vehicle reaching the road curvature.

Lighting assembly

A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.

A lighting apparatus includes a circuit board and light emitting diodes (LEDs) attached to the circuit board. The LEDs are arranged in an array of row and columns and are attached to the circuit board are arranged in a single plane. A support substrate supports the circuit board. Optical elements are configured to redirect light from the plurality of LEDs. Each optical element is substantially the same as all other optical elements. Each LED is associated with a single optical element and each optical element is associated with a single LED. The lighting apparatus is configured to direct light away from the circuit board so that the light is directed so as to illuminate a substantially rectangular area that is off-center relative to the light assembly. The substantially rectangular area has an edge that is at least 14 feet in length.

Utility bay luminaire

A high bay luminaire includes a heat sink having a substantially disc-shaped configuration. A light emitter, reflector, and housing are connected to the heat sink. The housing includes a first arm, a second arm, a top bar, a bottom bar, and a door moveable between an open position and a closed position. A driver is connected to and moveable with the door.

High-bay luminaire

A luminaire having a substantially two-piece housing with a first portion and a second portion, for example a cover and a base. The cover receives one or more control components. The base receives a light emitter assembly and the control component assembly is operatively connected to the lighter emitter assembly to control the light output therefrom. A lens assembly can be connected to the bottom of the base. Different mounting components can be connected to cover to connect the luminaire 10 to a support.

Systems and methods for coupling a metal core PCB to a heat sink

Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.

Trough-shaped lamp housing

A trough-shaped lamp housing (10) which is integrally produced in a deep-drawing process and has a housing bottom (11) and a housing wall (12) which laterally surrounds the housing bottom (11) and which, together with the housing bottom (11), delimits a lamp chamber, wherein the housing bottom (11) has a planar region (20, 25) for receiving at least one lamp component (120, 130) in a planar manner, wherein the planar region (20, 25) is circumferentially surrounded by a raised and/or recessed annular structure (35) which is integrally formed in a deep-drawing process, and wherein the housing wall (12) discontinues at the circumferential edge thereof that faces away from the housing bottom (11) in a circumferentially closed edge portion (16), which lies in a plane.

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 IDC 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.
