Abstract
An LED includes a light-emitting chip, a metal member, and a housing. The light-emitting chip generates light. The light-emitting chip is arranged on the metal member. The housing is combined with the metal member to fix the metal member. The housing has an opening portion exposing at least a portion of the light-emitting chip and the metal member. The metal member includes a base metal layer, a light-reflecting layer arranged on the base metal layer, and a protection layer arranged on the light-reflecting layer and including a metal.
Claims43
A lead frame, comprising:
- a base metal layer;
- a light-reflecting layer arranged on the base metal layer;
- and
- a protection layer arranged on the light-reflecting layer and comprising a metal.
A light emitting diode (LED), comprising:
- a metal member;
- a light-emitting chip arranged on the metal member, the light emitting chip to generate light;
- and
- a housing combined with the metal member to fix the metal member, the housing having an opening portion exposing at least a portion of the light-emitting chip and the metal member,
- wherein the metal member comprises a base metal layer, a light-reflecting layer arranged on the base metal layer, and a protection layer arranged on the light-reflecting layer and comprising a metal.
A backlight unit, comprising:
- a light guide plate;
- and
- at least one light emitting diode (LED) to provide the light guide plate with light, wherein the at least one LED comprises:
- a lead frame comprising a base metal layer, a light-reflecting layer arranged on the base metal layer, and a protection layer arranged on the light-reflecting layer and comprising a metal;
- and
- a light-emitting chip arranged on the lead frame.
