US 12,480,651 B2 · System and method for controlling the humidity and pressure in a luminaire

Abstract

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.

Dependent claims

A luminaire, comprising:

an enclosure comprising one or more luminaire components configured to modify and emit a light beam, the enclosure including a first opening and being otherwise sealed from external air;
and
a chamber comprising a drying agent and second and third openings and being otherwise sealed from the external air, wherein:
the chamber is coupled at the second opening by a sealed air coupling to the enclosure at the first opening;
the third opening comprises a membrane completely covering the third opening, the membrane comprising a material configured to allow air to pass through the material while reducing the passage of water droplets in the air;
and
the chamber is configured such that reduced air pressure in the enclosure at the second opening draws air into the chamber via the third opening.

A luminaire, comprising:

a first enclosure comprising one or more luminaire components configured to modify and emit a light beam, the first enclosure including first and second openings and being otherwise sealed from external air;
a second enclosure comprising electronic circuits electrically coupled to the luminaire components of the first enclosure, the second enclosure including a third opening and being otherwise sealed from the external air, wherein the first enclosure is rotatably mounted to the second enclosure and the first opening is air coupled to the third opening by a first rotatable sealed air coupling;
and
a chamber comprising a drying agent and fourth and fifth openings and being otherwise sealed from the external air, wherein:
the chamber is coupled at the fourth opening by a sealed air coupling to the first enclosure at the second opening;
and
the fifth opening comprises a membrane completely covering the fifth opening, the membrane comprising a material configured to allow air to pass through the material while reducing the passage of water droplets in the air.
