When architectural details require emphasizing, the lighting elements must respect the identity of the entire environment. The aesthetic lightness inherent to HR projector facilitates its integration in buildings characterized by a high heritage value, avoiding its visual distortion.
ORIGIN AND EVOLUTION
The HR series has been designed to extol the authenticity of urban space, revitalizing its essence by the accented encounter of light and form. Installation in façades or ceilings can generate direct or indirect light, depending on the requirements of each space.
Since the first edition of the HR series in 2009, the performance of the electronic and optical components has experienced an exponential evolution, while its argon gas technology APS® – IP68 has remained unchanged, demonstrating its reliability in critical applications subjected to the impact of rain, moisture and salinity.
MATERIALS AND STRUCTURE
HR projector body consists of a front Stainless Steel AISI304 structure, and a rear chassis made of anodized aluminum AL 5754, acting as a direct heat dissipation mechanism and structural element. Both elements are characterized by high corrosion resistance.
This chassis features an LED – APS® module with tempered glass cover. 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.
With the Argon Pressurised System (APS)® HR 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 Total Cost of Ownership (TOC) and maintains high demanding visual comfort standards
The HR projector 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.
