Lighting apparatus

A lighting apparatus, comprising:

• a housing including first and second back covers disposed on opposite sides of a center and each having an inside surface in a parabola shape;
• an recess opened at lower portions of the first and second back covers;
• a first light-transmissive sheet disposed in an oblique direction in a recess of the first back cover;
• a second light-transmissive sheet disposed in an oblique direction in a recess of the second back cover;
• a first light emitting module having a plurality of LEDs arranged in a first direction at a first corner of the recess of the first back cover;
• a second light emitting module having a plurality of LEDs arranged in the first direction at a second corner of the recess of the second back cover;
• a heat dissipation body in which the first and second light emitting modules are disposed in a region between the recess of the first back cover and the recess of the second back cover;
• and
• a first reflective sheet disposed adjacent to the LEDs in the inside surfaces of the first and second back covers, and reflecting first side light emitted from the plurality of LEDs,
• wherein the heat dissipation body includes a first heat dissipation portion in which the first light emitting module is disposed, a second heat dissipation portion in which the second light emitting module is disposed, a first reflecting portion disposed between the first heat dissipation portion and a lower end of the first light-transmissive sheet, and a second reflecting portion disposed between the second heat dissipation portion and a lower end of the second light-transmissive sheet,
• wherein the first reflective sheet has a plurality of reflective surfaces,
• wherein the first light-transmissive sheet includes a lower region which is disposed at a lower position than a first horizontal straight line with respect to the LEDs of the first light emitting module and an upper region which is disposed at a higher position than the first horizontal straight line, wherein a first end of the first light-transmissive sheet is in the lower region, and a second end of the first light-transmissive sheet is in the upper region, and
• wherein the second light-transmissive sheet includes a lower region which is disposed at a lower position than a second horizontal straight line with respect to the LEDs of the second light emitting module and an upper region which is disposed at a higher position than the second horizontal straight line, wherein a first end of the second light-transmissive sheet is in the lower region, and a second end of the second light-transmissive sheet is in the upper region, and
• wherein a first end of the first reflecting portion is to couple to the first end of the first light-transmissive sheet and a second end of the first reflecting portion is to couple to the first heat dissipation portion, wherein the first reflecting portion has a concave curved surface between the first end and the second end;
• and
• wherein a first end of the second reflecting portion is to couple to the first end of the second light-transmissive sheet and a second end of the second reflecting portion is to couple to the second heat dissipation portion, wherein the second reflecting portion has a concave curved surface between the first end and the second end.
