An insect trap configured to entice and collect insects using UV light, comprising: a main body; an insect passage unit detachably coupled to an upper side of the main body and selectively allowing insects to pass therethrough; an air collector disposed at a lower side of the main body; a motor disposed between the air collector and the insect passage unit; a suction fan disposed between the motor and the air collector and rotated by the motor; a UV LED installation unit disposed above the insect passage unit and provided with a UV LED module; a buttress separating the UV LED installation unit from the main body while supporting the UV LED installation unit above the main body while so as to allow insects to be suctioned into a space between the main body and the UV LED installation unit; and an insect collector for collecting insects detachably coupled to a lower side of the air collector and including a mesh through which air is discharged from the insect trap by the suction fan; wherein the insect passage unit has a lattice shape including a plurality of insect passage holes selectively allowing insects to pass therethrough, the plurality of insect passage holes being formed by a circular member and a radial member wherein the UV LED module comprises at least one chip-on-board type UV LED chip or at least one LED package mounted on a support substrate characterised in that the UV LED module comprises the UV LED chips mounted on both surfaces thereof to emit light in both directions of the UV LED module wherein the UV LED chips or the UV LED packages mounted on one surface of the support substrate are arranged so as not to overlap the UV LED chips or the UV LED packages mounted on the other surface of the support substrate. a main body; an insect passage unit detachably coupled to an upper side of the main body and selectively allowing insects to pass therethrough; an air collector disposed at a lower side of the main body; a motor disposed between the air collector and the insect passage unit; a suction fan disposed between the motor and the air collector and rotated by the motor; a UV LED installation unit disposed above the insect passage unit and provided with a UV LED module; a buttress separating the UV LED installation unit from the main body while supporting the UV LED installation unit above the main body while so as to allow insects to be suctioned into a space between the main body and the UV LED installation unit; and an insect collector for collecting insects detachably coupled to a lower side of the air collector and including a mesh through which air is discharged from the insect trap by the suction fan; wherein the insect passage unit has a lattice shape including a plurality of insect passage holes selectively allowing insects to pass therethrough, the plurality of insect passage holes being formed by a circular member and a radial member wherein the UV LED module comprises at least one chip-on-board type UV LED chip or at least one LED package mounted on a support substrate characterised in that the UV LED module comprises the UV LED chips mounted on both surfaces thereof to emit light in both directions of the UV LED module wherein the UV LED chips or the UV LED packages mounted on one surface of the support substrate are arranged so as not to overlap the UV LED chips or the UV LED packages mounted on the other surface of the support substrate.
