Light emitting package having a guiding member guiding an optical member

A light emitting device package, comprising:

• a base including a flat top surface;
• a plurality of electrical circuit layers disposed on the flat top surface of the base;
• a light emitting diode disposed on a region of the flat top surface of the base, wherein the region excludes the plurality of electrical circuit layers;
• an optical member comprising a light transmissive material configured to pass light emitted from the light emitting diode;
• and
• a guiding member having a closed loop shape surrounding the region for guiding the optical member,
• wherein the plurality of electrical circuit layers includes a first portion disposed between the flat top surface of the base and a bottom surface of the guiding member,
• wherein the first portion of the plurality of electrical circuit layers includes a first region and a second region spaced apart from the first region,
• wherein the plurality of electrical circuit layers includes a second portion disposed between the flat top surface of the base and the bottom surface of the guiding member,
• wherein the second portion of the plurality of electrical circuit layers includes a third region and a fourth region spaced apart from the third region,
• wherein the plurality of electrical circuit layers includes a first extension portion that extends from the first portion to a first location outside of an outer edge of the guiding member in a first direction,
• wherein the plurality of electrical circuit layers includes a second extension portion that extends from the second portion to a second location outside of the outer edge of the guiding member in a second direction, and
• wherein the first direction is antiparallel to the second direction.
