New BIRNS Aurora™

Introducing the new BIRNS Aurora™ Light Emitting Plasma Deep Submergence Light

Unparalleled, Brilliant 14,000 Lumen Light Output for High Performance Underwater Vehicle Use

OXNARD, CA – BIRNS, Inc., an ISO 9001:2008 certified global leader in the design and manufacture of unique lines of high performance lights, connectors, penetrators and custom cable assemblies for severe environments, has launched the most powerful, cutting-edge underwater vehicle light on the market: the new BIRNS Aurora™.  This high intensity Light Emitting Plasma (LEP) deep submergence light provides dazzling, electronically dimmable, 14,000 lumen brilliance to usher in the next generation of extreme depth subsea lighting systems.

LEP is an exciting new lighting technology that is a more powerful and efficient alternative to LED, Tungsten Halogen and Metal Halide lighting.  Its light sources use a solid-state device to generate Radio Frequency (RF) energy to power a plasma light source.  Unlike traditional metal halide lights, the BIRNS Aurora does not require metal electrodes to drive power into the source, thus has a more robust quartz vessel.  This unique LEP light has a 30,000 hour lamp life, and produces a continuous spectrum, and delivers an exceptionally high lumen density—in fact, the single bulb (approximately 2 mm long) produces a blazing 14,000 lumens of brilliant white light at 5,300K, at a Color Rendering Index (CRI) of 94.

The prototype BIRNS Aurora was unveiled last year. The original version had its electronics in a separate system from the housing.  In the final version, launched in January, the electronic driver is in the same pressure housing as the lamp.  Also new for 2012 is the seamless electronic dimming software (operable on any PC) which permits easy and continuous (ie, step-free) slide-bar dimming down to 20% —with no reduction in colour temperature or colour rendering index (CRI) performance. The software also has pre-set 10% dimming increments (at 90%, 80%, 70%, etc.) enabling the BIRNS Aurora to be dimmed with a single mouse click. The luminaire also has a hot-restrike feature which immediately brings the lamp to full brightness from any dimmed setting.

The potent BIRNS Aurora offers physical dimensions that are smaller and more efficient than costly metal halide systems, and is engineered with a  robust aluminum housing with a tempered 6km borosilicate glass lens.  It has an overall length of 15’’, so it’s immensely powerful, yet very low profile for a wide range of demanding applications.  With a mounting diameter of 4 inches, it can be tailored to fit large or small vehicles, and runs on 28Vdc with a 9.3A power draw, with a weight of 12 lbs in air and 7.5 lbs in sea water.

The connector for the system is a BIRNS Millennium 3M-9-BR, an electrical connector with nine pins, with an open face pressure rating of 6km. The connector series is a miniature, high density metal shell line, with contacts with 50 microns of hard gold plating, with standard exclusive features such as dual self-guiding stainless steel keys and keyways for positive indexing. The connectors are engineered with a 15° molded internal O-ring leading chamfer that’s specially angled to ensure the dual O-rings’ longevity and reliability.
