20140203315 | LED LENS AND LED PACKAGE USING THE SAME - A light emitting diode (LED) lens comprises a light incident surface on a bottom surface of the LED lens facing a light source. A light exit surface, having a size greater than the bottom surface, is defined by a top surface of the LED lens. A planar portion, emitting light incident through the light incident surface, is in a central region of the light exit surface. At least one protrusion portion, protruding to be stepped with respect to the planar portion, is in a region of the light exit surface except for the central region. A reflective surface, defined by lateral surfaces of the LED lens between the top surface of the LED lens and the bottom surface thereof, guides the light incident through the light incident surface, and contacts a lower portion of the light exit surface corresponding to a boundary between the protrusion and the planar portions. | 07-24-2014 |
20140204591 | LENS FOR CONTROLLING ILLUMINANCE DISTRIBUTION AND LIGHT-EMITTING DIODE PACKAGE INCLUDING THE LENS - A lens for controlling an illuminance distribution to realize high luminous flux efficiency by maintaining a required beam angle and uniformity on an illumination surface having a particular shape, such as a square shape, and a light-emitting diode (LED) package including the lens are provided. The lens includes an incidence surface onto which light emitted from a light-emitting device is incident, and an emission surface through which the light incident onto the incidence surface is emitted. An illuminance controller, which includes at least two optical devices, is disposed on the emission surface to control an illuminance distribution of the emission surface. | 07-24-2014 |
20150055348 | LIGHT EMITTING MODULE - A light emitting module is provided including a light emitting device and a reflective member disposed on the light emitting device. The reflective member includes a hole with an inner wall thereof provided as a reflective surface, having a lower aperture having a quadrangular shape and an upper aperture having a shape geometrically different from that of the lower aperture. The inner wall includes first to fourth inclined surfaces extending from respective sides of the lower aperture to the upper aperture, and first to fourth connection surfaces extending from a respective vertex of the lower aperture to the upper aperture to connect the inclined surfaces to each other. The illuminance distribution of emitted light has a quadrangular shape.
