    摘要: A system may include a memory configured to store instructions and a processor. The processor may be configured to execute the instructions to cause the system to determine a PWM frequency of the input PWM signal and generate a first PWM signal to power a first light emitting diode (LED), a second PWM signal to power a second LED, and a third PWM signal to power a third LED. Each of the first PWM signal, the second PWM signal, and the third PWM signal may have the PWM frequency of the input PWM signal and may be in phase with the input PWM signal.

    摘要: A lighting module comprises a heat sink with a body portion and a protrusion portion protruding from the body portion into a forward direction. An LED element is mounted on a mounting surface of the protrusion portion. The mounting surface is arranged facing partially backwards and forming an angle of 5-45° to the forward direction. An electrical plug connector is provided within the body portion's cavity and is electrically connected to the LED element. In the lighting system, a reflector assembly comprises a concave reflector with an inner reflector space. A lighting module is arranged such that its protrusion portion projects into the inner reflector space. Light emitted from the LED element is reflected by the reflector. The body portion is arranged outside of the reflector space. The lighting module may be replaced by separating the lighting module from the reflector assembly and providing a new lighting module.

    摘要: The invention relates to an optical arrangement including LED lighting elements arranged on a support surface. An optical axis X extends from the support surface. A first collimator unit includes at least one support element and first collimator elements. The support element is supported on the support surface between at least two of the LED lighting elements. The first collimator elements are arranged in front of the LED lighting elements in the direction of the optical axis X to collimate light emitted from the LED lighting elements. A second collimator unit is arranged in front of the first collimator unit in the direction of the optical axis X. The second collimator unit includes second collimator elements arranged in front of the first collimator elements to collimate light emitted therefrom.

    摘要: A lighting arrangement and a method of forming an illumination beam are described. A plurality of LED lighting elements is operable to emit light. A plurality of collimator elements is arranged to collimate light emitted from the LED lighting elements. A first projection element is arranged to project light emitted from the collimator elements onto a spatially controllable reflector element. The spatially controllable element comprises a plurality of reflector elements adjustable between a first and a second position. In the first position, the light is reflected into the direction of a second projection element to form a projected illumination beam. In the second position, light is reflected into a different direction to not contribute to the projected illumination beam.

    摘要: A lighting device, a method of manufacturing a lighting device and a support are described. A support includes a layered structure of alternating conductors and insulating layers. The layered structure includes a mounting section and a body section adjacent the mounting section. The mounting section includes at least one mounting face that has an arrangement direction and at least three alternating contact sections along the arrangement direction. Each contact section is electrically coupled to one of the conductors and separated from a neighboring one of the contact sections by one of the insulating layers. The body section has a width that protrudes sidewards from the at least one mounting face and a length that extends substantially parallel to the arrangement direction.

    摘要: The invention describes a method of manufacturing an LED module, comprising the steps of providing a translucent encapsulant comprising a number of layers to enclose a number of LEDs of the LED module; modifying the surface structure of an outer surface of a layer to form at least one dense scattering region corresponding to the position of an LED of the LED module; to form at least one sparse scattering region that does not correspond to the position of an LED of the LED module; and to form a transition scattering region between a dense scattering region and a sparse scattering region. The invention further describes an LED module, and a device comprising a device housing and at least one such LED module.
