Lumileds’ new LUXEON CZ LEDs build on LUXEON C Color Line, boosting intensity of narrow-beam-angle, undomed LEDs

To meet the recent market trend of color tuning fixtures with narrow beam angles and maximum punch, LED maker Lumileds of San Jose, CA, USA has launched the LUXEON CZ Color Line, a product line consisting of 21 LED color options including 13 color and 8 white LEDs, optimized to deliver maximum intensity. “The LUXEON CZ features up to 48% higher punch than any other undomed color LED,” claims LUXEON Color Family product line director Jennifer Holland.

In addition, the LUXEON CZ Color Line makes fixture designs with narrow beam angles possible. “It is easier for optics to pick up all the light because the emitters cast minimal light below the horizon, unlike comparative products on the market,” Holland adds.

In a narrow-beam system, the intensity of the light from the LUXEON CZ is nearly 30-50% higher compared with other undomed LEDs, it is claimed. The intensity of each color is similar, ensuring a consistent beam width and minimizing halos when color mixing.

The product line additionally eliminates crosstalk, ensuring a true color point when LEDs are packed closely together. Crosstalk can happen when direct color LEDs are closely spaced with phosphor converted LEDs. The photons from the direct colors can excite the phosphor in the surrounding phosphor-converted LEDs, making it appear as if the phosphor converted LEDs are on, when in reality only the direct color LED is illuminated. The LUXEON CZ Color Line ensures a true color point in compact designs and is especially suited to architectural lighting, entertainment lighting, dimmable lamps and fixtures and emergency vehicle lighting applications.

In addition, LUXEON CZ consists of the same robust buildings blocks as the LUXEON C Color Line. All LUXEON CZ and LUXEON C LEDs feature an identical focal length, leading to superior color mixing in all applications, it is claimed. To accelerate time to market and simplify designs, LUXEON CZ and LUXEON C are designed in the same footprint and are also hot tested at 85°C to ensure excellent performance at real-world conditions.

What is said to be the industry’s lowest thermal resistance (3.2°C/W) helps to reduce the size of heat sinks for the most compact lamps or fixtures. A low thermal resistance is especially beneficial in densely packed applications because it significantly helps with thermal management. Leveraging the features and reliability of the LUXEON C, Lumileds has extended these benefits to LUXEON CZ, giving lighting manufacturers the flexibility to use them individually or even together, Lumileds adds.
