Abstract

A multi-functional LED lamp is mainly composed of a lamp base, an illuminant device, a light guide device and a lampshade. The illuminant device is provided with plural LED bulbs planted on a laminate that is fixed on the lamp base with a heat-conductive medium spread in between. Heat generated by the illuminant device is dispersed by the lamp base. The light guide device is transparent, placed at a place where the illuminant device is to emit, used to conduct the light beams and promote its brightness. The lampshade is covered on the light guide device and the illuminant device. With features of low energy consumption, long service life and high luminous efficiency for LEDs and a good cooling member, the LED lamp is really energy saving and high-efficient.

Claims

1. A multi-functional LED lamp comprising:

a lamp base provided with a cooling member formed on its outer surface and a chamber formed inside it, and,

the lamp base comprises a plurality of fins and cooling particles assembled around the outer surface, and the lamp base is adhered on a piece of glass via a heat-conductive silicon rubber;

an illuminant device provided with plural LEDs welded on a laminate and installed in said chamber of said lamp base, and,

the illuminant device is adhered on the lamp base via coating with a heat-conductive silicon rubber;

a light guide device being transparent and formed as a particular shape to match with a light emitting method of said lamp and having its incident surface located at a particular side where said illuminant device is to emit and an emitting surface formed at its outer surface; and

a lampshade being a cover and covered on an outside of said light guide device and positioned on said lamp base.

2. The multi-functional LED lamp as claimed in claim 1, wherein said cooling member is formed integrally together with said lamp base.

3. The multi-functional LED lamp as claimed in claim 1, wherein said cooling member is made independently into components that are then assembled to said lamp base.
