sampling and volume availability of a complete line of 80x80mm rugged metal LED chips, including white, blue, and UV variations.
The EV-80mil family allows packagers and integrators a wider variety of high-efficiency/high- output choices to address the growing number of applications in both the commercial lighting and industrial spaces.
Earlier, the company also announced the 850nm Oslon Black SFH 4715A (pictured above), which boasts a typical electro-optical efficiency of 48 percent.
Commenting on the the SFH 4715A, Jörg Heerlein, senior manager for product marketing at Osram Opto Semiconductors said: “We are not aware of any other opto-electronic component with an optical efficiency to rival this one. Thanks to a boost in output to 800mW (previously 630mW) the new Osram IRED can illuminate objects over 100m away depending on the application and type of external optics. What’s more, this higher output generates more light, improving the image in the process.”
SemiLEDs Releases Complete line of 80mm rugged LED chips
Includes ReadyWhite kilolumen devices, blue and UV
With the new family, a single 80x80mil device will typically replace four 40x40mil LED chips, which simplifies packaging and optical designs, while minimising color fringing and shadow effects common to multi-chip implementations. SemiLEDs EV family, which combines vertical LED architectures with rugged copper-alloy substrates, has proven to be especially well-suited for handling the increased thermal and electrical demands of large-chip implementations.
Tuttle, general manager for SemiLEDs Optoelectronics Co, commented: “Applications in commercial and residential lighting, along with UV industrial applications, share the common challenge of achieving high output in compact form-factors, in the most cost-effective manner. SemiLEDs’ unique vertical-metal architectures allow these devices to be driven hard, without compromising either their stability or reliability, allowing packagers and integrators to deliver maximum optical power from extremely small package or chip-on-board footprints.”
Tuttle continued: “The EV-80mil line is also able to deliver substantial versatility, including die- level white options that incorporate SemiLEDs’ proprietary ReadyWhite(tm) phosphor coating technology, which minimises blue-leakage and delivers impressive levels of color uniformity with tight binning options for low-profile and multi-colour white packaged LEDs.”
The new EV-80mil ReadyWhite chips incorporate SemiLEDs’ proprietary phosphor technology, and when packaged in a typical 5x5mm ceramic package, can be expected to deliver up to 1200 lumens at 3A. They are available in correlated colour temperatures (CCTs) ranging from 2600 to 10,000K with colour rendering indices from a minimum 65 to a minimum of 90, after packaging.
