Therefore, more heat will be generated when working. It is necessary to use some heat dissipation equipment to export the heat and emit it into the environment. Otherwise, the service life of LED equipment will be affected or even lead to failure to work. Due to the limitations of current technological development, heat dissipation has always been an important challenge for LED lighting.\n\n0.32 inch <a href=\"\" style=\"color: #333;\">3141AW</a> LED Common-Cathode CC <a href=\"\" style=\"color: #333;\">3141AW</a> 7-Segment digit <a href=\"\" style=\"color: #333;\">3141BW</a> Display <a href=\"\" style=\"color: #333;\">3141BW</a> Common-Anode CA\n\n<hr style=\"border:1px solid;\">\n\n<a href=\"\" style=\"color: #333;\">Electrode contact for LED heat dissipation</a>\n<a href=\"\" style=\"color: #333;\">Aluminum nitride as LED heat dissipation substrate</a>\n<a href=\"\" style=\"color: #333;\">LED thermal dispersion solutions</a>\n<a href=\"\" style=\"color: #333;\">Ceramic heat dissipation substrate and LED luminous</a>\n<a href=\"\" style=\"color: #333;\">LED grains heat substrate formed</a>\n<a href=\"\" style=\"color: #333;\">Metal circuit layer for LED thermal dispersion</a>\n<a href=\"\" style=\"color: #333;\">Film ceramic substrate is suitable for high power LED</a>\n<a href=\"\" style=\"color: #333;\">Improve LED luminous efficiency by heat dissipation </a>\n<a href=\"\" style=\"color: #333;\">Led cooling system</a>\n<a href=\"\" style=\"color: #333;\">LED photoelectric conversion and heat dissipation</a>"}],"tree":{"_id":"2664852031dc48f42700001d","name":"LED photoelectric conversion and heat dissipation","publicUrl":"led-photoelectric-conversion-and-heat-dissipation"}}
