Light emitting diode lamp
First Claim
1. A light-emitting-diode lamp comprising:
- a resin body having a generally cylindrical form, with a convex hemispherical top, and an external surface formed as a frosted surface, and a base portion opposite the top; and
a light source in the base portion of said resin body, wherein;
said light source comprises a light-emitting-diode chip directed to emit light mainly towards said hemispherical top; and
said external frosted surface of said resin body is adapted so that uniformly diffused light is emitted by the lamp in all directions except backward through said base.

Abstract
An LED lamp according to the present invention emits light approximately in all directions like a small filament lamp. The LED lamp is a light emitting bulb-shaped unit, and comprises an epoxy resin bulb-shaped portion; two leads of which one end is extended outside the bulb-shaped portion and the other end is embedded in the bulb-shaped portion; and an LED chip connected to the ends of the two leads and embedded in the bulb-shaped portion. The surface of the bulb-shaped portion of the LED lamp is formed in an appropriate process to be a frosted glass surface, a cut-diamond surface, a surface covered with small particles, or an optically-diffusing cap. Thus, a durable, non-fragile, and small power-consuming LED lamp can be obtained.
