Thermal management and luminaire’s construction
The doublepower!! TREE luminaire’s body is manufactured from extruded anodized aluminium profile. The body surface and heat sink fins are shaped to deliver the most efficient heat dissipation from the light source, and to minimize dust accumulation. The concept was tested not only in the laboratory, but also on prototypes in real-life operations.
We pay great attention to heat-conducting material application. It serves the purpose of conducting the heat away from the LED chips. Even a very small bubble of one millimetr leads to chip’s burnout within few months. In doublepower!!, we use special heat-conducting tape and proven adhering procedure with exceptional and sustainable cooling results.
Due to the sophisticated body shape of the luminaire doublepower!! TREE LED and an emphasis on workmanship, the difference between the ambient temperature and the temperature on the LED chip reference point is not more than 18 °C. In other words the temperature of the chip reaches only 78 °C at ambient temperature of 60 °C. These values are completely unique for LED luminaires.
Such resilience predetermines the doublepower!! TREE LED to be applied even in extreme conditions. Even at very high temperatures, the source’s maximum efficiency is ensured, as well as the long lifetime and very slow decrease of luminous flux over time.
With lower ambient temperatures, the lifetime and luminaire’s output increases, which accounts for additional benefits in case of installation in “standard” industrial conditions.
Powering the chips
Unlike other competing products, LED chips in doublepower!! TREE are powered well below their maximum power supply current and in accordance with the recommendations of the chip producer, who guarantees their lifetime on the basis of tests. Usually, we do not power the chips to more than 60 % of their maximum supply current. The tests (e.g. TM21 directive) confirm that powering the chips below the maximum supply current has a very positive effect on the chip’s lifetime and it also slows down the luminous flux loss. It is one of the reasons why we can guarantee our luminaires lifetime of minimum 100,000 hours.
Many producers encounter difficulties with high levels of glare (UGR) with regards to their luminaires. In order to ensure low glare levels, we embedded the LED modules deeper in the body of the doublepower!! TREE luminaire. The radiance is regulated by suitable optics and/or larger reflectors’ surface. In this manner, we achieve low levels of glare while maintaining very high efficiency of the luminous flux.
For special application (local lighting, spaces where quality control takes place, etc.), doublepower!! TREE luminaires can be equipped with a diffuser, which further lowers the UGR values.
