LED Engin, Inc.'s tunable white light engine LuxiTuneTM replaces halogen style dimming and colour tuning downlight applications. The new version of LuxiTune offers many additional features including a Correlated Colour Temperature (CCT) tuning function that enables users to separately adjust the CCT, between 2100 K and 4300 K, and light intensity (flux). Tracking along the same tune curve, the existing halogen style dimming mode allows users to dim from 3000 K to 1800 K. In both modes of operation, the tune curves have been precisely designed to stay a short distance below the black body locus throughout the tuning range, resulting in more vibrant colours. Additionally, LuxiTune 2.0 has newly added DMX control functions, such as switching in between halogen dim and CCT tune modes. In the second quarter 2014, LED Engin plans to further expand the LuxiTune product range with additional DALI control functionality and 700lm and 2000lm versions.
LuxiTune delivers warm, soft tones of dimmed light in a compact single emitter while maintaining colour quality and consistency within 3 Standard Deviation Colour Matching (SDCM) throughout the dimming range. LED Engin's robust multi-channel LuxiGen(TM) emitter platform in concert with LuxiTune's thermal feedback control eliminates the known effects of varying light output over temperature and time from different colour dies, providing exceptional flux and colour stability over the life of the product.
Providing high lumen density and Lux-on-TargetTM performance, LuxiTune has a luminous flux of 1100 lumens, equivalent to a 60W halogen lamp. Luminous efficacy is 63 lm/W at temperature including the secondary optic, far higher than that of rival products. At full intensity, Colour Rendering Index (CRI) is 90 and LuxiTune maintains a CRI average of 85 as it dims. Class leading in size, compact 45mm diameter optics - available in 24°, 34° and 45° beam angles - support the development of compact lighting fixtures and are far easier to integrate into downlights with beam swivel features.
