PURPOSE: An air circulation light emitting diode (LED) ball bulb is provided to form an air outlet at the upper side of a housing, to separate a heat absorbing plate and an inverter at a certain distance inside the housing, and to form an inverter outlet, thereby cooling heat with discharging the inside air of the housing through the inverter outlet and the air outlet. CONSTITUTION: An air circulation light emitting diode (LED) ball bulb comprises a socket connected to an electrode, a housing coupled with the socket, an inverter which is mounted inside the housing and supplies power to an LED module, a heat absorbing plate at lower side of the inverter, the LED module which adheres to the heat absorbing pate and includes an LED substrate in which an LED element is installed, a glass bulb which is coupled to the lower side of the housing and includes the LED element inside. The inside air of the housing is discharged outside through air outlets. The air outlets penetrate the upper side of the main body of the housing at certain distances. The inverter is installed at the internally upper side of the housing. The inside air of the housing is discharged through inverter outlets at the substrate of the inverter. The heat absorbing plate is separated from the inverter inside the housing at a certain distance so that a space is formed between the inverter and the heat absorbing plate. The inside air of the space absorbs heat from the LED element, and is discharged through the inverter outlets and the air outlets so that the heat is cooled. |
