摘要:
Disclosed is a light emitting diode (LED) package having an array of light emitting cells coupled in series. The LED package comprises a package body and an LED chip mounted on the package body. The LED chip has an array of light emitting cells coupled in series. Since the LED chip having the array of light emitting cells coupled in series is mounted on the LED package, it can be driven directly using an AC power source.

Disclosed are a light emitting diode (LED) module and a lighting assembly. The lighting assembly comprises a light emitting device, a driver integrated circuit device for driving the light emitting device, a heat sink for dissipating heat generated from the light emitting device, and a heat shielding portion for blocking thermal interference between the driver integrated circuit device and the light emitting device. In the LED module, the driver integrated circuit device is disposed on the heat shielding portion. Accordingly, it is possible to block thermal interference between the light emitting device and the driver integrated circuit device and to decrease the size of the lighting assembly.
