Aluminium is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, nonmagnetic, and ductile.
Aluminum is widely used in lighting industry. Why Aluminium is the Best Lighting Material? Here are some of the advantages aluminium has over other materials when it comes to lighting:
Lightweight
Aluminium has a weight of 2.7 g/cm 3. In other words, it’s a very lightweight metal. This makes it easier to transport and install, keeping the cost of our LED lights down.
Malleable
Aluminium is also very malleable. This means products of aluminium can be formed close to the end of the design process, streamlining high-volume production. With rising manufacturing costs, this is definitely an added benefit.
Strength
While aluminium is relatively easy to manipulate, don’t think that for one second it isn’t a sturdy material! Once we add alloys, aluminium provides great structural support; a strength to weight ratio that is superior to steel. Additionally, unlike most steel grades, aluminium does well in cold environments. The lower the temperature, the more aluminium’s strength increases, making it ideal for our outdoor and industrial lights.
Corrosion Resistance
When exposed to air, aluminium naturally generates a protective oxide coating that is highly corrosion resistant. This makes it ideal for lighting near coastal areas as it becomes resistant to chemicals such as sulfur and chlorides, while being electronically insulating.
Heat Management
Arguably, heat management is one of the most important factors in extending the life expectancy of an LED light. So what is it? It’s the technology of preventing and reducing the build-up of heat in LED chips, which are sensitive to prolonged heat exposure. Management is mainly accomplished by the design and composition of the light’s heat sink (the ridged metal fixture attached to the back of the LED). Aluminium heat sinks are by far the best, as aluminium is a great thermal conductor. Additionally, our aluminium dishes are deep, not shallow, adding more surface and material for heat dissipation than other models. This helps us extend the life span of our LEDs for you.
Reflectivity
Aluminum has a visible light reflectivity of around 80% and can also reflect heat. This together with its low weight makes it a great reflector for our LED light fittings.
