Publication number: 20230414531Abstract: A luminaire is provided, having an enclosure and a chamber air coupled to the enclosure. The enclosure includes luminaire components that emit a light beam, has an opening, and is otherwise sealed. The chamber includes a drying agent, two openings, and is otherwise sealed from the external air. One opening of the chamber is coupled by a sealed air coupling to the opening of the enclosure. The other opening of the chamber is completely covered by a membrane that allows air to pass through the material while reducing the passage of water droplets in the air. The enclosure may include sensors that measure air pressure, air humidity, and/or air temperature of the enclosure. The luminaire may include a control system configured to collect data from the sensors and to send information related to the collected data to a user of the luminaire via a communication channel.Type: ApplicationFiled: January 5, 2023Publication date: December 28, 2023Inventors: Pavel Jurik, Josef Valchar

Publication number: 20230417402Abstract: A luminaire includes an enclosure, an air valve, and a chamber. The enclosure includes a sealed cover and light beam emitting components. The air valve is air coupled between the enclosure and the chamber. The chamber includes a drying agent and has an opening with a membrane completely covering the opening. The membrane passes air while reducing the passage of water droplets in the air. The air valve blocks air passage between the enclosure and the chamber when closed. A method for testing to determine adequate sealing of an enclosure of a luminaire includes closing an air valve to seal the enclosure from outside air, activating a heat-generating component, determining whether an air pressure in the enclosure increases by more than a threshold value, and sending a signal indicating a result of the determination. The method includes deactivating the heat-generating component and opening the air valve.Type: ApplicationFiled: October 10, 2022Publication date: December 28, 2023Inventors: Pavel Jurik, Jindrich Vavrik, Josef Valchar

Patent number: 11774075Abstract: A luminaire includes a luminaire mechanism, a stepper motor, an absolute multi-turn rotational position sensing system, and a control system. The stepper motor moves the luminaire mechanism. The absolute multi-turn rotational position sensing system includes absolute rotational sensors that detect absolute positions of a cam indexer on the motor shaft and an indexer wheel coupled to the cam indexer. The indexer wheel rotates by a predetermined amount in response to one full rotation of the cam indexer. The control system determines an absolute position of the luminaire mechanism based on information from the absolute rotational sensors relating to the positions of the cam indexer and the indexer wheel. The control system receives a commanded position for the luminaire mechanism and causes the stepper motor to move the luminaire mechanism to the commanded position based on the absolute position of the luminaire mechanism.Type: GrantFiled: March 31, 2022Date of Patent: October 3, 2023Assignee: Robe Lighting s.r.o.Inventors: Pavel Jurik, Jindrich Vavrik, Josef Valchar
