I am trying to understand how the Phantom Contour Projector technically works. Do you have a section or cut away illustration showing all the internal components of the lighting fixture, especially the lenses in the optical chamber?
The Phantom Contour Projector until December 2019 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.
In January 2020 the 75 watt halogen projector 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. An finally, by reducing the heat load load all Phantom recessed framing projectors are IP Rated for direct contact with insulation.
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.
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.
Our lighting manufacturing facility is located in Houston, Texas with professional lighting sales agents located throughout the United States that enable us to service all 50 states including Washington DC, Nashville Tennessee, Las Vegas Nevada. Portland Oregon, Oklahoma City Oklahoma, Tucson Arizona, Long Beach California, Atlanta Georgia, and Los Angeles California.
