Profiles meet the needs of luminaireThorlux Lighting has designed a new luminaire specifically for industrial and warehouse applications. The new light fitting uses LEDs as the light source as opposed to the conventional sodium, mercury discharge, or fluorescent lamps, as they have a longer life span and therefore have lower maintenance costs.
The luminaire is built with two aluminium extrusions from Sapa Profiles, which allowed Thorlux to build in a number of design features that address specific issues for the product's application. The extrusions are designed and fitted together so a hinge runs along the length of the luminaire. The Thorlux light fitting uses aluminium extrusions so the luminaire can be produced in three different lengths. The shortest version is 1.1m in length and uses 68 LEDs and consumes 140watts. The longest is 2.1m long, uses 136 LEDs and consumes 275 watts.
Although LEDs are only small they generate a lot of heat. The thermal properties of black anodised aluminium have been utilised in the extrusion to conduct heat away from the LEDs and their electronic drivers. One of the extrusions has large fins to increase the surface area and dissipate heat and as the environment that the luminaire will be used in is particularly prone to dust, the fins point downwards to avoid the accumulation of dust which could reduce the fins' effectiveness.
