news digest ♦ LEDs Everlight shows off its Shwo
D LED lighting series The firm’s new LED combines high power, luminosity and value for money for advanced lighting applications
Taiwanese firm Everlight Electronics is introducing a brand new high power, high brightness LED package, the “Shwo D” Series.
Intematix unveils remote phosphor for high-intensity LED lighting
The addition of the latest ChromaLit product expands the market with high lumen output and neutral off-state colour
Intematix, an innovator of patented phosphors and phosphor components for high-quality LED lighting, has released the ChromaLit XT.
This is the latest product in the award-winning ChromaLit line of remote phosphor technology.
Using a phosphor composite substrate separated from the blue LEDs, ChromaLit is claimed to increase light quality and lower systems costs. Intematix says improving on the conventional approach where phosphor coats the blue LEDs directly, ChromaLit offers glare-free, diffuse light, high colour rendering and consistent light quality.
By only using a blue LED engine instead of binned white LEDs, production is streamlined and inventories are reduced. What’s more, system efficacy is increased by up to 30%, reducing lighting system material cost and power consumption.
LED from the Shwo D series
This powerful bright and economic LED series come in a compact 3.5 x 3.5 x 0.58mm ceramic package.
The Shwo D series is a surface-mount high-power device featuring high brightness that is suitable for all kinds of lighting applications such as general illumination, flash, spot, signal, industrial and commercial lighting. With a standard operating current of 350mA, the Shwo D family can be driven at 1 W.
The minimum luminous flux (lm) of the 1W Shwo D can be up to 110 lm at 6500K (CCT) or 80 lm at 3000K (CCT) when driven at 350mA of current.
The thermal pad of this device is electrically isolated providing convenience in thermal and electrical design. The Shwo D series also has the advantage of low thermal resistance. It is one of the most promising devices in Everlight’s high power Lighting Series product offering and is ready to face the challenges of today’s Solid-State Lighting requirements. .
With ESD protection up to 8KV, the soldering method is SMT and the moisture sensitivity is level 1 . The LED is RoHS compliant and matches ANSI binning. The lumens maintenance testing conforms to IESNA LM80 test method applications. Directional lamps incorporating the LED are the MR16, GU10, and PAR . These are suited to spot lighting, flash and street lighting.
Intematix says the ChromaLit XT offers a powerful and elegant solution for new applications like spotlights and floods, extending ChromaLit technology’s light quality and adding higher light intensity, 65% lower cost per lumen. It is also claimed to enhance off-state neutral colour when compared to conventional remote phosphors that are yellow in colour. ChromaLit XT were on display for the first time at the Light+Building trade fair in Frankfurt, Germany during April 15th to 20th.
“ChromaLit XT is designed for the many applications that need high lumen output from a small space,” says Julian Carey, Senior Director of Marketing at Intematix. “Lighting designers and architects will appreciate the ability to take advantage of ChromaLit’s substantial benefits without sacrificing aesthetics based on ChromaLit XT’s unique off-state neutral colour.”
“ChromaLit XT allows us to push the envelope when it comes to providing higher outputs for smaller lighting apertures incorporating remote phosphor technology,” adds Andrew Littler, Director of Vexica, an LED lighting solutions company.
Vexica’s LUMAERA-50-RP module incorporates ChromaLit XT to provide customers with a wide range of LED solutions without expensive research and development costs. “The high CRI we can achieve with our LUMAERA-50 module using ChromaLit XT is a huge advantage for professional specification clients such as lighting designers and architects. Intematix is offering us a solution that gives us a competitive advantage in the high quality lighting arena.”
ChromaLit XT is optically treated to maintain an off-state neutral appearance in order to look as good off as it does on – perfect for lighting designers. The added design freedom of ChromaLit XT means users can let exposed lights like pendant lamps and downlights integrate with the rest of the space without
