The disclosure provides a light fixture comprising at least one first light source configured to emit a main light beam in a main light emission direction, and a front lens configured to guide the main light beam at an exit surface where the main light beam exits the light fixture. A plurality of second light sources ( 300 ) near the front lens are provided configured to illuminate the front lens with a plurality of second light beams, wherein the front lens comprises a lens body in which at least one channel is provided, the at least one channel comprises a plurality of scattering elements, wherein the plurality of second light sources are configured to illuminate the plurality of scattering elements.

A light fixture is provided, comprising a light fixture housing with a housing sidewall extending circumferentially around a movable lens. The light fixture housing forms an inner space that includes at least one light source for emitting light through the movable lens. The movable lens is arranged on a light output side of the light fixture housing and is movable along the housing sidewall relative to the at least one light source. A sealing element is positioned between the housing sidewall and the movable lens, in order to seal the inner space from the exterior environment outside the light fixture. The movable lens defines a cavity in the housing on the light output side. This cavity is at least partially bounded by the movable lens and the sealing element on its inner side, while remaining open to the exterior on the light output side.

Systems are provided for an optical device. The optical device includes a light emitting diode in face-sharing contact with a light mixing rod. A resilient member is configured to maintain the light mixing rod in face-sharing contact with the light emitting diode throughout a range of motion of the optical device.

A flag actuation system for a lighting fixture is disclosed. The flag actuation system includes an actuator, an actuator axle connected to and drivable by the actuator, and at least two flags, each flag being movable between a first position in which the flag is arranged in an optical path defined by the flag actuation system, and a second position in which the flag is arranged out of the optical path. Each flag is individually and detachably connectable to the actuator axle via a magnetic actuator connection, and each flag is retainable in the first position using a first magnetic retaining connection and in the second position using a second magnetic retaining connection.

Systems are provided for an optical device. The optical device comprises a lens actuation system including a motor, a flywheel, a connecting linkage, a plurality of articulating arms, and a lens. The lens is housed in a frame coupled to the articulating arms and driven via the lens actuation system between an upstream position and a downstream position.

The application relates to a light fixture comprising a compartment housing at least one light source configured to emit light in a main light emission direction. A lens is provided movably arranged relative to the light source in direction of the main light emission direction, and an electric motor configured to move the lens relative to the light source in direction of the main light emission direction. A control unit determines a current used by the electric motor to move the lens in the main light emission direction, wherein the control unit is configured to detect a presence of a liquid on the lens based on the determined current.

A method for controlling a subtractive color mixing system in a light fixture, comprising a light source, the subtractive color mixing system comprising a plurality of subtractive color filters, and an additional filter. The method is for emitting light having a target color upon having traversed the additional filter, such as upon having traversed the subtractive color mixing system and the additional filter and optionally being emitted from the light fixture. The method comprising receiving target information indicative of, such as defining, the target color, calculating a target control setpoint for each subtractive color filter within the plurality of subtractive color filters based on the target information, and calibration data, which for a plurality of sets of calibration control setpoints is indicative of an emitted color, controlling each of the subtractive color filters according to each calculated target control setpoint for each of the subtractive color filters.
