Slenderness and dynamism to redefine the role of light in daily life. The Round series triggers new forms of aesthetic magnetism in the urban space through balanced proportions, simplicity of stroke and the visual cleanliness of the whole.
ORIGIN AND EVOLUTION
The Round series represents a new response based on elementary geometric lines that blends timelessness and simplicity with slenderness and dynamism through a flat design concept. Its mission is to create a universe of sensations adapted to the soul of each space, generating a sense of intimacy and warmth through positional photometric distributions, or a sense of fascination and security through directional photometric distributions.
Since the Round series was launched, many cities have experienced its ability to maximize thermal conductivity and neutralize the corrosive effects of moisture in the LED optical module. We continue to strike a balance between form and functionality with this icon of the SETGA brand.
MATERIALS AND STRUCTURE
The upper body Round luminaire consists of a machined and anodized aluminium chassis, which serves as a direct mechanism for heat dissipation, as well as a structural element known for high corrosion resistance. The underside of the luminaire is characterized by the application of a tempered glass cover onto which a city logo can be vitrified. Both upper and lower elements are encased in an anodized aluminium AL6063-T5 frame.
The development of an optical system with HTS® technology has led to an 8% increase in ultimate luminaire efficacy, reducing reflection losses by 55%, compared to market standards that apply a secondary lens system covered with a tempered glass closure.
The design strategy of the Round series is characterized by the combination of highly sustainable materials. Compared to injected aluminium, high purity aluminium Al 5754 facilitates reuse by other industries in the future. The 100% glass natural origin makes this material fully recyclable and minimizes the environmental impact of its transformation process.
The support of the first European glass processing line powered by solar technology has substantially reduced the carbon footprint of this series. Finally, after the latest revision of the ISO 14001, and implementation of a sustainability master plan, SETGA has driven the design of a long-term recycling system for each component in the Lined series.
With the Argon Pressurised System (APS)® Round series’ optical and electronic components are encapsulated in a pressurised atmosphere of argon gas. A watertightness level of IP68 is ensured, making the system resistant to complete and continuous immersion far beyond the requirements of any regulation.
The inert atmosphere in the optical-electronic module guards against condensation, moisture and salinity intrusion, thereby preventing an accelerated ageing process of the system’s sensitive components. This protective shield is essential in areas where air salinity is a critical lifetime factor for any optical and electronic component.
The ability of this system to preserve the lifetime, efficacy and chromatic quality of the luminaire reduces Up toal Cost of Ownership (TOC) and maintains high demanding visual comfort standards.
The Round luminaire is based on the principle of direct thermal dissipation between the LED PCB, the compact aluminium chassis and the exterior. The luminaire body comprises a continuous heat pipe of anodized aluminium AL-5754, which achieves thermal conductivity levels of 160 W/metre Kelvin, compared to 130 W/metre Kelvin of aluminium injection. The low porosity of anodized aluminium plus a thermal pad over the contact surface between the PCB and the dissipation body significantly reduce the diode’s junction temperature.
The redefined composition of the optical system delivers a 55% reduction in reflection levels, a significant drop when compared with market standards that apply a secondary lens scheme and a tempered glass cover. HTS technology enables optical performance levels similar to those obtained with a direct lens system, increasing the overall efficacy of the luminaire (lm/W) by 8%.
Dimensions and installation
The ultra-compact design of the Round luminaire achieves a unique visual effect with a thickness of only 31mm and a diameter of 457mm. Due to its small size, the Round is usually bet on green spaces and low heights.
The anchoring system with 4 bolts is designed to facilitate its anchoring to plates allowing some clearance in the position of the anchoring holes.
The design is also optimized to fit perfectly with our range of columns so that the arm merges seamlessly with the Round. The specific arm of some of the compatible columns allows a pitch regulation from 15 ° to ascending front..
