Lighting device

A lighting device comprising:

• a heat sink which comprises one surface and a receiving recess;
• a light emitting module which is disposed on the one surface of the heat sink;
• and
• a power controller which electrically connected to the light emitting module and is disposed in the receiving recess of the heat sink,
• wherein the light emitting module comprises a first light emitting module and a second light emitting module,
• wherein the first and the second light emitting modules emit white light,
• wherein the white light of the first light emitting module has a color temperature different from that of the white light of the second light emitting module,
• wherein the one surface of the heat sink comprises a first seating recess in which the first light emitting module is disposed and a second seating recess in which the second light emitting module is disposed, and
• wherein the first seating recess and the second seating recess are partially connected with each other.

A lighting device comprising:

• a heat sink which comprises one surface and a receiving recess;
• a light emitting module which is disposed on the one surface of the heat sink;
• and
• a power controller which electrically connected to the light emitting module and is disposed in the receiving recess of the heat sink,
• wherein at least three light emitting modules are provided,
• wherein the at least three light emitting modules are disposed on the one surface of the heat sink in the shape of “T”, and
• wherein the white light of the first light emitting module has a color temperature different from that of the white light of at least one of the second and the third light emitting modules.
