New general-purpose CoB LEDs compatible with common optics and other components
With the launch of the LUXEON CS CoB LED series, Lumileds now supports all three of the CoB board footprints that are widely used by the lighting industry.
Lumileds has expanded its range of chip-on-board (CoB) LEDs to support all three of the board formats that are widely adopted by lighting equipment manufacturers.
The LED industry has not specified standard footprints or boards sizes for CoB LEDs, unlike for other types of LEDs. Nevertheless, the ecosystem of suppliers of components such as CoB holders and optics have largely designed their products to support three common board formats. The introduction of the new LUXEON CS series means that Lumileds now offers LUXEON CoB LEDs in a 13.5 mm x 13.5 mm footprint, as well as the 19.0mm x 19.0mm and 28.0 mm x 28.0 mm sizes.
Now lighting equipment manufacturers can select LUXEON CoB LEDs as drop-in replacements for other models, without having to redesign their board. In doing so, they will benefit from the excellent efficacy, color stability, and reliability of LUXEON CoB LEDs.
The new LUXEON CS CoB products are general-purpose LEDs which match the performance of the existing Lumileds LUXEON Core and LUXEON CX CoB LEDs. They are available in color temperature options of 2700 K, 3000 K, 3500 K, 4000 K, 5000 K, 5700 K and 6500 K, and with a minimum CRI of 80 or 90.
The LUXEON CS Pro CoB LEDs are spectrally tuned for retail lighting, illuminating merchandise with a brighter and sharper light.
The LUXEON CS HE LEDs offer very high efficacy.
