Light emitting diode module and back light assembly
The present application presents a light emitting diode module comprising a substrate including a first insulating layer, a second insulating layer, and a metal layer between the first and the second insulating layers; a groove formed at the first insulating layer for exposing the metal layer; and a light emitting element disposed at the groove, and including an LED chip and body part surrounding the LED chip, wherein the LED chip contacts the metal layer for radiating heat.
1. A backlight assembly comprising:
a cover bottom containing an optical film;
a substrate disposed on the cover bottom, and having a mounting hole to expose an upper surface of the cover bottom;
a light emitting element including a molding part mounted on the upper surface of the cover bottom exposed by the mounting hole;
a reflective plate having a hole corresponding to the light emitting element, and disposed between the cover bottom and the optical film; and
a lead part disposed on a wall of the mounting hole and directly connected to each of the upper surface of the cover bottom and the substrate,
wherein the light emitting element includes an LED chip disposed on the lead part,
wherein the molding part includes a body portion and a lens portion, and
wherein the molding part is directly connected to an upper surface of the lead part located on an upper surface of the substrate.
2. The backlight assembly according to the claim 1 , further comprising:
a heat radiating sheet disposed between the substrate and the cover bottom,
wherein the heat radiating sheet directly contacts the lead part, a bottom surface of the substrate and the cover bottom.
3. The backlight assembly according to the claim 1 , further comprising:
a heat radiating plate disposed between the LED chip and the cover bottom.
