How to make LED lamps better heat dissipation?

    The industry's LED lamp bead bracket is basically made of silver, and its heat dissipation is very good. From the material analysis , the thermal conductivity of metal:
Silver 429 Copper 401 Gold 317 Aluminum 237 Iron 80 Tin 67 Lead 34.8

     In contrast, a good heat sink is silver, followed by copper. But consider the cost of silverware. No one will use pure silver and pure copper for heat dissipation. Pure aluminum is also less estimated. However, the combination of copper and aluminum in the industry is quite good. The so-called copper-aluminum bonding is a perfect combination of copper and aluminum with a certain process, so that copper quickly transfer heat to aluminum, and then heat is dispersed by a large area of ​​aluminum, which not only increases the thermal conductivity of aluminum Copper also compensates for the fact that copper does not dissipate heat as much as aluminum and organically combine to achieve rapid heat transfer and rapid heat dissipation.

     Whether it is current silver, copper, aluminum, or copper and aluminum combined heat. In the future, heat dissipation from light sources to finished products will only become more scientific and complete.
