CBB, CAB & Ultra-Bright™

Ultra-BrightTM Technology: CAB – Coat “After” Bend Technology
Our constant investment in R&D have turned out some extraordinary results – a unique combination of manufacturing processes and advanced materials that push the performance and quality levels of LCDL lamps beyond your expectations. We call this process simply “Ultra-BrightTM”.

  • Double the efficacy (lm/watt)
  • 50% improvement in lumen maintenance
  • Maximized lighting uniformity

After 10,000 hours of use, Ultra-BrightTM lamp (left) made with our new process technology performs and looks significantly better than a standard technology lamp (right) with equal hours. The left picture shows no evidence of phosphor degradation or glass discoloration when compared to the standard lamp.

What Could This Mean for Your Application?
That’s quite easy. You will definitely experience slashed power requirements, greatly extended maintenance intervals and enhanced display readability in bright ambient light.

Ultra-BrightTM will benefit any hot or cold cathode, bent fluorescent lamp from 8mm to 25mm diameter. Our LCD Lighting proprietary manufacturing process eliminates any performance loss at the bends. Overall, Ultra-BrightTM lamps deliver more total lumen output for a given wattage input.

  • Improved display brightness, uniformity and readability
  • Brighter diffusion to reduce device power requirements.

Ultra-Bright vs. Standard Lamp Maintenance, 15mmPhosphor Batch Stability
Our preferred phosphor sources and rigorous batch quality testing assures repeatable peak performance. The unique blue phosphor we use and our other superior quality phosphors combine to increase luminance by up to 33%. Precision application of a measured, even layer of phosphor is the key to Ultra-Bright’sTM outstanding luminance uniformity and extraordinarily low lumen depreciation.

How the protective layer contributes
Our advanced overcoating material and proprietary lamp processing techniques deliver significantly better protection against Hg ion bombardment of the phosphor layer and solarization of the glass.

 

Coat “After” Bend: CAB Technology
As known in the art, fluorescent lamp tubes are normally shaped prior to the application (CBB) of a phosphor material. More specifically, a fluorescent lamp tube is formed by first heating and then bending an uncoated glass tube into the desired form (CAB), e.g. serpentine, circular, U-shaped, or L-shaped. After being formed, the interior of the glass tube is coated with a phosphor material. This process is termed the Coat After” Bend process in the fluorescent tube manufacturing arts.

Coat “Before” Bend: CBB Technology

Unlike our Coat “After” Bend (CAB) technology, where lamps are bent first and the phosphor is applied as a second step, the Coat “Before” Bend (CBB) technology works in a standard and traditional way. We first coat a straight stick of glass with phosphor and then bend it into the lamp shape desired.

The CBB procedure is a less costly bending procedure and the resulting uniformity, output and performance is also much less than our CAB and Ultra-BrightTM Technology.
