The bracket of Imitation of lumen encapsulation
The high power led module provide a bracket to toggle led core. there are has three kind of bracket for led user to choose.

Copper brackets: The copper sleeve comprises a upper copper sleeve and a lower copper sleeve fixed inside the supporter by the coaxial; copper bracket owned high thermal conductivity, high electrical conductivity and excellent high temperature strength, high-temperature creep resistance, good wear-resistance and so on, It is found out from test that, the efficiency of white LED using copper brackets is higher than iron brackets, moreover, the light decay is lower about 10%..but That is a little higher than iron bracket.

Iron brackets: an iron frame to hold the led module straight are all iron bracket their ability to conduct both heat and electricity is the relatively poor.the iron bracket has favourably priced.

Aluminium alloy brackets: aluminium alloy may be used for led brackets. The Aluminium alloy brackets has the advantages of simplicity, convenient wedge connection, and good firmness. and aluminum alloy brackets doesn’t rust(aluminium is a noncorrosive metal). so the bracket costs are higher.
