WebThermal Conductors. Conduction is the transfer of thermal energy between particles of matter that are touching. Thermal conduction occurs when particles of warmer matter bump into particles of cooler matter and transfer some of their thermal energy to the cooler particles. Conduction is usually faster in certain solids and liquids than in gases. WebA light-emitting diode and electrode structure technology, which is applied in the direction of electrical components, circuits, semiconductor devices, etc., can solve the problems of poor thermal conductivity, high heat, and difficult heat dissipation of light-emitting diode chips, so as to improve the service life and facilitate the effect of heat dissipation
