LED driver capability to offer efficient

Lumitex West, formerly Poly-Optical Products, provides strategically-located design of engineered lighting solutions with volume manufacturing from Lumitex Asia’s new production facility in Taipei,” according to Scott Diestel, Western Regional Manager for Lumitex.  “This design and production capacity rounds out our domestic resources in Cleveland, Ohio.Diestel added that the West Coast center can provide backlighting designs using the full range of fiber optic technology, including UniGlo? and other innovative fiber optic panels to light cell phone keypads, computer keyboards and a variety of membrane switch applications that require tight space tolerances and minimal thicknesses. Using SMT LED light sources, Lumitex panels provide exceptional thinness (to 0.2 mm), uniform brightness and low power, with no heat or EMI, outstanding design flexibility, quick turn-around and low NRE, unit, assembly and maintenance costs.

Additional features to be available include triac dimming, color temperature regulation, ambient light control and vacuum encapsulation for added durability. IP67, UL1310 Class 2 and other key regulatory approvals are pending. The drivers will be available as standard, off-the shelf product or in custom designs. ERG will maintain a full in-house engineering staff at its U.S. headquarters to meet virtually any special application requirement.ERG has been a specialist in power conversion solutions since 1979. The company designs and manufactures its own magnetic components. ERG originally introduced its Smart Force(TM) line of LED Drivers to provide full-function power supplies for LED-backlit LCDs, and has now broadened its LED driver capability to offer efficient and economical LED drivers for offline and DC powered solid state lighting applications ranging from 1W to 200W.

The Oslon LED has a thermal resistance of 7K/W. Its small size gives designers the flexibility to create extremely sophisticated solutions. If particularly strong light is needed, several light sources can be combined in a cluster. In addition to ultra-white (5700 to 6500 K), the LED will be available this summer in neutral white and warm white. Its color temperature will range from 2700 to 4500 K.The Oslon SSL is manufactured using the latest chip technology, ensuring a high luminous efficacy. At an operating current of 350 mA this light source provides a typical brightness of 110 lm in ultra-white (5700 and 6500 K), with a maximum possible luminous flux of 130 lm at present. At an operating current of 350 mA and a color temperature of 3000 K it achieves a typical efficiency of 75 lm/W and a brightness of 85 lm. And when the operating current increases to 700 mA (warm white), the brightness is as high as 155 lm. The advantage here is that applications that demand high lighting levels can be completed with fewer LEDs.
