Common materials for street lighting lamps housing

Understanding the street lighting lamps commonly used materials, will be helpful for the correct selection and reasonable use of street lamps.

Commonly used material of lamps shell is aluminum and glass steel. Both the characteristics of them are light weight, corrosion resistance, high strength, and is suitable for mass production. The difference is glass steel is lighter than aluminum, but the rigidity and heat resistance, heat dissipation is worse than aluminum. Aluminum production casing need casting process, including high pressure die casting (die casting), low pressure die casting (gravity casting) and sand casting. When the casting, in order to shorten the clotting time, increase liquidity, increase the corrosion resistance, to add different materials in aluminum, such as silicon, copper, aluminum alloy with different components. In comparison, the high pressure die casting shell can be made thinner, lighter, more beautiful, more people like to use, of course, the production cost will be higher, the price is high.

If the lamp to install ballast and other accessories, then it should be divided into two parts. The front part (the light source cavity) installed of the light source and reflector. The back part (the electrical apparatus cavity) installed ballast and trigger, the majority of lamps installed compensation capacitor. The electrical apparatus cavity due to the connected with a lamp stand, bear the weight of the whole lamp, sometimes bear strong wind pressure, so the best selection of it is high mechanical strength, and can be processed into complex shapes of aluminum production. And the light source cavity only the installation of the light source and the reflector, is not an important component, shape can also not complicated, if the lamp body with enough volume words, can use glass steel, so as to exert the advantage of light.

Sometimes the street lamps shell can be made of a thin steel plate. Its advantages are high mechanical strength, low cost, and is suitable for mass production. Disadvantage is high demand on surface corrosion.
