Led Bead Bracket.P4 indoor LED Display

　　Currently, there are aluminum brackets, brass brackets, and copper brackets available in the mall. Aluminum brackets are the cheapest, with a price of 0.06 yuan for a 1w imitation lumen, 0.12 yuan for brass, and around 0.16 yuan for copper. Aluminum brackets have the worst thermal conductivity, followed by brass, and red copper is the best (we pay great attention to the heat dissipation of the shell when selecting it, and also pay attention to the quality of the power supply. The shell and power supply prices are very high, and usually the selection of LED lamp beads is getting worse, putting the cart before the horse). At present, the lamp beads arranged for 0.4 to 0.6 yuan in the mall are made of aluminum brackets, with a base of 0.6 to 0.8 yuan. The base is made of brass brackets, with a base of 0.8 to 1 yuan. The base is made of copper brackets. Even if it is a copper bracket, there are 40, 60, 80, 100 and other options available in Duyin, and the prices vary greatly, ranging from 0.13 yuan to 0.18 yuan. A base of 0.8 yuan is made of 60 pieces of silver, while a base of 1 yuan is made of over 80 pieces of silver. Many packaging factories promise that the brackets are made of red copper, which is originally brass or adulterated red copper.
