1. A lighting apparatus comprising:
a heat radiation frame having a first receiving space;
at least one light emitting device on the heat radiation frame;
a diffusion frame provided on the heat radiation frame to protect the at least one light emitting device and diffuse a light emitted from the at least one light emitting device;
a support frame received in the first receiving space of the heat radiation frame and having a second receiving space; and
at least one module received in the second receiving space;
wherein the heat radiation frame comprises an upper end portion having a flat top surface,
wherein a horizontal heat radiation plate is disposed on the upper end portion of the heat radiation frame and comprises at least one of a thermal conductive silicon pad and a thermal conductive tape;
wherein the module is provided under the heat radiation plate, and
wherein the support frame comprises:
a first outer surface having a constant curvature;
a second outer surface more inward than the first outer surface of the support frame and vertically extending from an upper end portion to a lower end portion of the support frame; and
a third outer surface protruded outward from the first outer surface of the support frame and vertically extending from the upper end portion to the lower end portion of the support frame;
wherein the heat radiation frame comprises a groove formed on an upper surface of the upper end portion thereof and corresponding to the at least one light emitting device;
wherein the horizontal heat radiation plate comprises an insertion hole formed therethrough and corresponding to the at least one light emitting device;
wherein the groove is aligned with the insertion hole in a horizontal direction; and
wherein a roughness of an inner surface of the diffusion frame is greater than a roughness of an outer surface of the diffusion frame.
