LED LUMINOUS FLUX CONVERTING LENS AND LIGHTING APPARATUS INCLUDING THE SAME |
| 摘要 |
A light emitting device (LED) luminous flux converting lens including a bonding portion that bonds the LED luminous flux converting lens to a supporting plate to fix the LED luminous flux converting lens. The LED luminous flux converting lens includes a bonding portion that protrudes from a boundary of an upper surface in a horizontal direction, and the bonding portion includes a first portion and a second portion having different thicknesses. The LED luminous flux converting lens includes a bonding portion that protrudes from a portion of a boundary of the upper surface in a horizontal direction. A luminous flux efficiency of the LED luminous flux converting lens may be increased by reducing loss in a luminous flux due to the bonding portion. |

1. A light emitting device (LED) luminous flux converting lens comprising:
a lower surface that is separated from a substrate on which an LED is mounted, the lower surface facing the LED; an upper surface that is larger than the lower surface and is parallel to the lower surface; an outer side surface that extends from the lower surface to the upper surface; and a bonding portion that protrudes from a boundary of the upper surface and is bonded to a supporting plate that fixes the LED luminous flux converting lens, wherein the bonding portion comprises a plurality of first portions and a second portion that is thicker than the first portions in a vertical direction. |
