Abstract
The invention provides a metal and ceramic mixed heat-dissipating LED ball bulb lamp, belonging to the technical field of LED illumination. The heat dissipating part of the lamp has enough air contact surface by using metal of a standard lamp holder part and a heat dissipating material of an outer shell, and high heat conductivity material copper or aluminum is used as a secondary heat conducting medium. Heat energy is sequentially transferred to a heat conducting bin (4) made of a high heat conductivity metal material and the standard lamp holder metal part used for connecting a standard lamp holder, and a part of heat energy is dissipated directly through the metal of the filament lamp standard lamp holder and the heat-resisting material of the outer shell. The heat-dissipating outer shell is made of aluminum oxide ceramics. The heat conducting bin made of the high heat conductivity metal material is reliably connected with the aluminum oxide ceramics in heat conduction by using the characteristics of high air permeability and continuous elasticity close contact of a relatively medium heat conductivity metal spring (6), and different thermal expansion coefficient stresses of aluminum alloy metal and ceramics are effectively overcome.
