First, as shown in FIG. 5, in the case of the comparative example in which the second lower surface 322 is a vertical plane perpendicular to the upper surface 21 of the multi-body 2, the LED is in the first direction D1. The light emitted toward the arrow direction is emitted toward the first direction (D1 arrow direction) while passing through the second reduction surface 322. That is, the comparative example is irradiated as it is toward the non-illumination area after the back-illumination light emitted by the LED passes through the second lower surface 322.

Next, as shown in FIG. 4, in the case of the first embodiment implemented as the inclined surface inclined toward the second direction (the D2 arrow direction) as the second lower surface 322 extends in the upper direction (UD arrow direction), The light emitted by the LED toward the first direction (D1 arrow direction) may be refracted toward the second direction (D2 arrow direction) while passing through the second lower surface 322. Accordingly, all or part of the light emitted by the LED toward the first direction (D1 arrow direction) may be emitted toward the second direction (D2 arrow direction). Therefore, the first embodiment can reduce the light intensity irradiated toward the non-illuminated area after the back-illuminated light emitted by the LED passes through the second reduction surface 322, so that the light pollution to the non-illuminated area Etc. can be reduced. In addition, in the first embodiment, since all or part of the rear-illuminated light emitted by the LED may be irradiated toward the lighting area after passing through the second lower surface 322, the brightness of the lighting area may be increased. have. Therefore, the first embodiment can contribute to enhancing the lighting performance for the lighting area.

The second reduction surface 322 may be formed in a plane inclined toward the second direction (D2 arrow direction) as it extends upwardly (UD arrow direction). In this case, an included angle between the second lower surface 322 and the upper surface 21 of the multi-body 2 may form an obtuse angle. The first lower surface 321 may be formed in a plane inclined downward (DD arrow direction) as it extends in the second direction (D2 arrow direction). An included angle between the first lower surface 321 and the second lower surface 322 may form a right angle.

4, 6, and 7, the optical lens 3 may include a plurality of protruding members 33.

The protruding members 33 may be formed to be inclined in the second direction (D2 arrow direction) to correspond to the second lower surfaces 322. Accordingly, the protruding members 33 have a function of refracting light emitted from the LED toward the first direction (D1 arrow direction) from the LED toward the second direction (D2 arrow direction). It can be implemented to be maintained.

The protruding members 33 may be formed to decrease in size as they protrude from the second lower surface 322, respectively. In this case, the protruding members 33 may be formed such that the protruding surfaces 331 (shown in FIG. 7) arranged to face the first direction (the direction of the arrow D1) form a curved surface. Accordingly, the protruding members 33 may scatter light by refracting the light passing through the second lower surface 322 toward the third direction (D3 arrow direction) and the fourth direction (D4 arrow direction). The third direction (D3 arrow direction) and the fourth direction (D4 arrow direction) are parallel to and opposite to the second axial direction (Y-axis direction). Accordingly, the LED illumination multi-lens 1 according to the first embodiment of the present invention uses the protruding members 33 to pass the light irradiated toward the non-illuminated area after passing through the second lower surface 322. Since it can scatter, light pollution to the non-lighting area can be further reduced. Each of the protruding members 33 may be formed in a semi-cylindrical shape having a long length in an inclined direction so as to correspond to the second lower surface 322.

The protruding members 33 may protrude from the second lower surface 322 such that the protruding surfaces 331 are connected to each other along the third direction (D3 arrow direction). In this case, the protruding surfaces 331 may be connected to each other along the second axis direction (Y-axis direction). Accordingly, the LED illumination multi-lens 1 according to the first embodiment of the present invention can reduce the amount of light irradiated toward the non-illuminated region without passing through the protruding members 33, so that the non-illuminated region is not included.
