Abstract

An apparatus for etching multiple surfaces of a hydroformed powder coated luminaire reflector is described. The system includes a laser, one or more high speed scan heads, a laser marking station and a conveyance device. The system positions a reflector into optical alignment with the scan heads to allow permanent etching of the surface thereof.

Claims (15)

1. A method of etching the interior surface of a powder coated luminaire reflector, comprising:

conveying a reflector into a laser ablation station through an infeed conveyor;

closing a first door position on one side of said ablation station;

positioning said reflector into optical alignment with a laser scan head;

ablating an interior surface of said reflector with a laser beam emanating from a laser;

opening a second door positioned on a second side of said ablation station;

conveying said reflector through an outfeed conveyor.

2. A process of laser etching a powder coated luminaire reflector, comprising:

orienting a luminaire reflector in a marking position on a conveyor system;

conveying said luminaire reflector into a laser etching station;

stopping said luminaire reflector in said laser etching station, wherein said marking position of said luminaire reflector is in optical alignment with a laser scanning head;

ablating a surface of said luminaire reflector in said marking position; maintaining a vacuum source in said laser etching station during said ablating;

passing said luminaire reflector out of said laser etching station;

blocking or filtering said laser using walls of said laser etching station, and

raising a first door of said laser etching station for conveying said luminaire into said station and raising a second door of said laser etching station for passing said luminaire out of said laser etching station.
