Light emitting device array

A light emitting device array comprising:

• a light emitting device package comprises a light emitting device and a body comprises first and second lead frames electrically connected to the light emitting device;
• and
• a substrate on which the light emitting device package is disposed, the substrate comprises a base layer and a metal layer disposed on the base layer and electrically connected to the light emitting device package, and an insulating layer disposed on the metal layer,
• wherein the metal layer comprises:
• first and second electrode patterns electrically connected to the first and second lead frames;
• and
• a heat dissipation pattern insulated from at least one of the first and second electrode patterns, absorbing heat generated from at least one of the base layer or(and) the light emitting device packages and then dissipating the heat,
• wherein at least one of the length or(and) width of the insulating layer is lower than at least one of the length or(and) width of the base layer.

A lighting system comprising:

• a light emitting device array comprises a light emitting device package comprises a light emitting device and a body comprises first and second lead frames electrically connected to the light emitting device, and a substrate on which the light emitting device package is disposed, the substrate comprises a base layer and a metal layer disposed on the base layer and electrically connected to the light emitting device package;
• and
• a light guide plate adjacent to the light emitting device array and change point emission light emitted from the light emitting device package into surface emission light,
• wherein the metal layer comprises:
• first and second electrode patterns electrically connected to the first and second lead frames;
• and
• a heat dissipation pattern insulated from at least one of the first or(and) second electrode patterns, absorbing heat generated from at least one of the base layer or(and) the light emitting device package and then dissipating the heat.
