Abstract

A light emitting module and a lens are disclosed herein. The light emitting module includes a plurality of light emitting devices arranged on a substrate and a plurality of lenses respectively disposed on the plurality of light emitting devices to disperse light emitted from the light emitting devices, wherein each of the plurality of lenses includes a A light incident portion of light emitted by the light emitting device and a light exit portion through which light received by the light incident portion exits; each of the light incident portion and the light exit portion has a major axis and a short axis in a plan view, the major axis of the light incident portion perpendicular to the long axis of the light-emitting part. The light emitting modules provide a substantially rectangular light distribution so that uniform light is emitted in combination with the light distribution of adjacent light emitting modules.

Description

[0001] This patent document claims priority and benefit from Korean Patent Application No. 10-2017-0026197 filed on February 28, 2017, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a light emitting module and a lens, and more particularly, to a light emitting module and a lens capable of specifying light emission distribution. Background technique [0003] A light emitting diode is an inorganic semiconductor device that emits light generated by recombination of electrons and holes. Recently, light emitting diodes have been widely used in various fields such as displays, automobile lamps, and general lighting. Light emitting diodes have long lifetime, low power consumption and fast response time, and thus are rapidly replacing existing light sources. [0004] For displays and general lighting, a few to several tens of light emitting diodes can be used. When using multiple LEDs, it is important t...
