HEAT DISSIPATING MEMBER FOR LED LAMP

摘要

A heat dissipating member (1) in an LED lamp in which an LED element is housed. The heat dissipating member (1) is formed by press-forming an aluminum alloy sheet to form a substantially conical shape. The aluminum alloy sheet is preferably a pre-coated aluminum alloy sheet formed by pre-coating one or both sides of an aluminum alloy sheet substrate with a synthetic resin coating film (21) containing a heat-dissipating substance. The synthetic resin coating film (21) preferably contains one or more substances selected from the group consisting of titanium oxide, carbon, silica, and zirconium oxide as the heat-dissipating substance.
