The Phantom LED Optical Framing Projector
In January of 2019, the existing 75 watt halogen projector (detailed below) was discontinued and replaced with a 26 watt Cree LED light engine. This was not just a simple lamp change, but a major redesign of the projector that improved light levels, energy efficiency and overall performance. The LED transformation included changing the electrical power supply from a 12VAC transformer to a 24VAC LED driver, updating the optical system with achromatic focal lenses and installing a high output 3000K LED light engine with active cooling fan for maintenance free operation. The unique tri-dimming LED driver is compatible with forward phase (MLV), reverse phase (ELV) and 0-10V dimming systems. The achromatic focal lenses have all but eliminated the spectral abnormalities (blue edge) associated with a focused light source. Finally, by reducing the heat load load, all Phantom recessed framing projectors are now IC-Rated for direct contact with insulation.
Now you see why this type of equipment is so specialized and not marketed by every lighting manufacturer. Here at Phantom Lighting System, we are committed to producing only finest lighting instruments designed specifically for illuminating fine art. Check out our framing projector spec sheets for more technical information of selecting focal lenses, determining where to mount the projector and photometric data.
The Original Phantom Halogen Optical Framing Projector
Until December 2019, the Phantom Contour Projector utilized a 75-watt MR16/FO halogen lamp designed originally for the fiber optic industry. This specialty halogen lamp produces a 13mm diameter circle of light at the focal point roughly 40mm from the lamp. The highly concentrated halogen light then passes through a 13mm aperture basically removing any stray light created by the lamp reflector and redirecting it inside the projector housing.
This focused light then passes through two Pyrex glass condenser lenses. The first lens is a 60mm, 75fl BCX (bi-convex) lens. The second lens is a 60mm, 150fl PCX (plano-convex) lens. Both condenser lenses collect the light and magnify the intensity of the light as it travels through the condenser assembly.
After passing through the masking ring, which holds the adjustable masking shutters or brass confinement plate, the light is then reprocessed and distributed to the art by one or more 39mm, 75fl Pyrex glass focal lenses. The focal lenses are the one variable in the system that allow the installer to manipulate the beam of light from a spot to a flood. All other lenses are fixed. The lighting designers at Phantom Lighting System have been awarded a US PATENT for innovation and design.
For existing customers interested in switching from halogen to an LED light source, don’t worry, we offer a Phantom LED Conversion Kit with everything you need in the box to make the transition.
