Abstract
Exemplary embodiments of the present invention relate to an LED lamp including a substrate, a first LED, a second LED, a heat sink, and a transparent cover. The first LED is arranged on a first surface of the substrate. The second LED is arranged on a second surface of the substrate, the second surface being an opposite side of the substrate from the first surface. The heat sink has a mounting surface on which the substrate is arranged. The heat sink also has a reflection surface. The transparent cover covers the substrate, the first LED, and the second LED.
Claims21
A light-emitting diode (LED) lamp, comprising:
- a substrate;
- a heat sink disposed on a first surface of the substrate;
- at least one first LED disposed on the first surface of the substrate;
- a transparent cover connected to the heat sink, the transparent cover covering the at least one first LED;
- and
- a reflection layer disposed on the heat sink,
- wherein the transparent cover comprises a lower portion disposed on the heat sink, and an upper portion disposed on the lower portion, and
- wherein the reflection layer is configured to reflect light emitted from the at least one first LED towards the lower portion of the transparent cover.
A light-emitting diode (LED) lamp, comprising:
- a heat sink;
- a substrate disposed on the heat sink, a first surface of the heat sink contacting a second surface of the substrate;
- and
- at least one first LED disposed on a first surface of the substrate;
- wherein the heat sink comprises a second surface adjacent to the first surface, and a reflection surface disposed on the second surface.
