A lighting apparatus is disclosed. The lighting apparatus may be an omni-directional LED light source. The lighting apparatus may include a heat sink and at least one LED module provided on the heat sink. The LED module may be mounted on a mounting block that protrudes a prescribed height over the heat sink. A first reflector may be provided over the heat sink and below the LED module, and a second reflector may be provided over the LED module. An upper surface of the first reflector may be sloped at a first prescribed angle with respect to a central vertical axis of the heat sink, and a bottom surface of the second reflector may be sloped at a second prescribed angle with respect to the central vertical axis of the heat sink. The first and second reflectors reflect light emitted from the LEDs to produce omni-directional light patterns.
