Dec 18, 2017: The Tridonic portfolio has been expanded to include a complete accessory package of lenses with various beam characteristics. The lenses are suitable for all DC LLE 24 mm modules and are easy to mount. For the three-row LLE 55 mm modules, the company also provides the corresponding optics enabling various light distributions for applications in offices and shops.
The lens geometry is flat at 13 mm and can also serve as protection against accidental contact for the LED module in the form of a cover. The 24 mm lenses are available in standard lengths of 1,200, 1,500 and 1,800 mm, as well as in further special lengths.
This accessory package supports luminaire manufacturers in developing luminaires in a quicker and more cost-optimised way. Thanks to the high-quality PMMA materials used in the manufacture of the lenses, they achieve optical efficiency of up to 95 percent.
The following light distributions are possible with the optics:
• “Intense” is well-suited for use in low-bay luminaires used in production halls and warehouses.
• “Batwing” has been designed for luminaires that need to achieve high light homogeneity at a low ceiling height.
• “DASY” has been specially designed for shelf lighting in shops. In addition to high vertical illuminance at eye level, the distinctive feature of this lens comes in the form of its even lighting of corridors. This lens enables corridors with a width of up to 2.4 m and a ceiling height of 3.5 m to be well lit.
• For the illumination of specific highlights on the walls, the “ASY” lens creates a wallwasher effect and high evenness with low colour shift over the elevation angle at the same time.
