OptoElectronix ULE5000 light engine spins bright ideas with Bayer MaterialScience LLC’s flame retardant, clear plastic
To make a ceiling fan light engine with LEDs instead of incandescent light bulbs, OptoElectronix needed a clear plastic that met the most-stringent Underwriters Laboratory (UL) standards.
“We needed to find a clear, UL 94 5VA-rated material that offered impact resistance for our ULE5000 Universal Light EngineTM module,” said Pat Miller, applications engineering manager, San Jose, Calif.-based OptoElectronix. “Bayer MaterialScience guided us toward the correct material. In fact, they’re the only company that had a material that satisfied all our needs, including the UL standards.”
The material – Makrolon® FR7087 polycarbonate – is believed to be the first transparent 5VA polycarbonate at 3 mm, optimized for LED light transmission.
“To pass the 5VA rating, the plastic cannot deform significantly with a flame physically in contact with the material for a period of 30 seconds,” said Miller. “Furthermore, the material has strong impact resistance, which also allows us to pass an additional requirement of UL.”
The plastic is used in the lens assembly of the ULE5000 Universal Light Engine module. The module is round with a diameter of approximately 8 inches and is 1-½ inches high. Originally designed to operate as a solid state light (SSL) option for a ceiling fan light, the ULE5000’s high-output light with isotropic dispersion pattern is also ideal for drum lights, large cylinder lighting, semi-flush lighting, rectangular wall sconces, bollard lighting, and stand-alone bowl lights, Miller explained.
Typically, the ULE5000 will last as long as the application in which it is used, meaning it may not ever need to be replaced. It also generates far less heat and is over three times more energy efficient than incandescent or halogen bulbs. Specifically, it features a 100-watt equivalent to incandescent light output, consumes approximately 30 watts of power and offers up to 50,000 hours of life, according to OptoElectronix.
In addition to meeting the UL 94 5VA requirements, the polycarbonate plastic offers a clear, glass appearance with the renowned impact strength and moldability of Makrolon polycarbonate. The plastic also has very good light transmission (close to 90 percent at 3mm) while having around 1 percent haze.
The material has been issued a UL Plastic Recognition Yellow Card and listed on the UL Online Certifications Directory at http://tinyurl.com/FR7087-yellow-card after being subjected to rigorous UL testing, including glow wire flammability and ignition.
