A luminaire control system comprising a plurality of luminaire heads and a remote device; wherein each luminaire head comprises: a sensor assembly for measuring at least one tilt angle for an angular positioning of the luminaire head, and a control module for controlling the sensor assembly to perform measurements during a first period upon activation of the luminaire head after installation thereof on a mounting base, and for controlling communication such that measurement data from said first period and an identification of the luminaire head is communicated to the remote device; wherein the remote device is configured to determine position information data for each luminaire head, based on the received measurement data, indicating whether the luminaire head is positioned correctly; and the luminaire control system further comprising at least one notification module for receiving the position information data from the remote device and for notifying a field operator accordingly.

An angle adjustment and rotation system comprising a first element attachable to a luminaire stand, and a second element configured to be attachable to a luminaire head, the first element and second element comprising substantially complementary shapes, and an attaching element configured to have a first state in which it tightly attaches the first element to the second element and a second state in which it movably attaches the first element to the second element. In the second state, the attaching element enables a rotation over substantially 180 degrees of the second element with respect to the first element. A method of controlling the orientation of a luminaire head connected to a luminaire stand is also proposed, preferably using the proposed system.

A downlight apparatus has a rotatable base, a light module and a front cover. The light is rotatable in a spherical rotating space defined by the rotatable base. There is a stop structure for keeping the light module staying at rotating angle with respect to the rotatable base when there is no external force applying on the light module.

The present disclosure relates to a lighting device for a vehicle, including a housing unit positioned on a vehicle body and configured to have an opening, a light source unit positioned on the housing unit and configured to radiate light, a reflection unit provided in the housing unit and configured to reflect the light, radiated by the light source unit, by differently setting a reflection angle for each section, and a screen unit positioned on the housing unit and configured to cover the opening and implement grill lighting by transmitting the light reflected by the reflection unit.

A lighting fixture includes a light source holder, a pair of position adjustors, and an outer shell. The light source holder holds a light source. The position adjustors are arranged to face each other and interpose the light source holder between themselves and supports the light source holder to allow the light source holder to rotate around a first virtual axis defined as a virtual axis passing through the position adjustors. The outer shell has an opening in which the light source holder and the position adjustors are arranged and supports the position adjustors to allow the position adjustors to rotate around a second virtual axis defined by a normal to an opening plane of the opening. The first virtual axis intersects with the second virtual axis and is located either within or behind the opening plane.

A lighting assembly and a lighting lamp. The lighting assembly includes a light source assembly and a connection assembly. The light source assembly includes a casing, a light source plate arranged on the casing, light emitting units arranged on the light source plate, and a first electrical terminal electrically connected with the light source plate. The first electrical terminal is connected to the casing. The connection assembly includes a bracket, a connection rod mounted inside the bracket, and a second electrical terminal arranged at an end of the connection rod. The first electrical terminal and the second electrical terminal are in plugging and running fit to supply power to the light emitting units. A rotating shaft of the light source assembly and the connection assembly is parallel to an axis of the connection rod.

An illumination system for a lighting assembly comprises a light assembly configured to selectively illuminate an operating region in a surgical suite and a plurality of light sources positioned within the light assembly and configured to emit light. The system further comprises at least one imager configured to capture image data and a controller. The controller is configured to scan the image data in at least one region of interest for a shaded region and identify a location of the shaded region within the region of interest. The controller is further configured to control the light assembly to activate at least one of the light sources to emit light impinging on the shaded region within the region of interest.
