Abstract
Light-emitting diodes (LED) are rapidly replacing conventional light bulbs in light applications because of their increased life span and energy efficiency. LED light bulb is used in various places, and the installation angle can vary based on the application and the environment, which significantly affects the cooling of the LED. If the heat dissipation performance of the LED light bulb is insuffi-cient, both the life of the LED and its luminous efficiency decrease. In this study, we analyzed the flow characteristics and thermal performance of cooling apparatus which has the vent in bulb case and is using the PCB as a heat sink. Furthermore, the thermal performance change of PCB heat sink according to the installation angle was analyzed.
