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.
