Lumileds Announces LEDs With Extra 'punch'


Luxeon CZ Color Line features maximum usable light for a variety of applications.

Lumileds has introduced the Luxeon CZ Color Line, a product line optimised to deliver greater intensity, or 'punch'. "The Luxeon CZ features up to 48 percent higher punch than any other undomed colour LED," said Jennifer Holland, product line director of the Luxeon Color family.

To meet the recent market trend of colour tuning fixtures with narrow beam angles and maximum intensity, Lumileds has developed the Luxeon CZ colour Line, which consists of 21 LED colour options including 13 colour and 8 white LEDs.

The Luxeon CZ colour 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," said Holland.

In a narrow beam system, the intensity of the light from Luxeon CZ is nearly 30-50 percent higher compared to other undomed LEDs. The intensity of each colour is similar, ensuring a consistent beam width and minimising halos when colour mixing.

The product line additionally eliminates crosstalk, ensuring a true colour point when LEDs are packed closely together. Crosstalk can happen when direct colour LEDs are closely spaced with phosphor converted LEDs.

The photons from the direct colours 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 colour LED is illuminated. The Luxeon CZ colour Line ensures a true colour 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 award-winning Luxeon C colour Line. All Luxeon CZ and Luxeon C LEDs feature an identical focal length, an approach that leads to superior colour mixing in all applications. 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 85degC to ensure excellent performance at real world conditions

The industry's lowest thermal resistance (3.2degC/W) helps 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.
