  • Publication number: 20090010022
    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.
