The invention discloses a shade-body external heat conduction and dissipation type full-power LED (
Light Emitting Diode) lamp comprising a back shade, a heat collector, an LED light-emitting
chip, two end shades, a light-gathering tile, a front shade and a light-transmitting shade, wherein the light-transmitting shade is arranged on the front shade; the back shade and the front shade are glidingly fastened and coordinated and are buckled with the two end shades to constitute a lampshade; the heat collector is arranged on the inner
vertical axis of the lampshade; the LED light-emitting
chip and the light-gathering tile are optically coordinated and arranged on the heat collector; and a heat conduction fin arranged on the inner wall of the back shade and the heat collector are connected in a heat
conductivity way. In the invention, a shade-body self-heat-dissipation structure is provided and the shortcomings that the heat dissipation area is restricted and the heat dissipation requirement of a high-power
LED lamp cannot be satisfied in the prior art as a heat dissipation structure is directly arranged on the LED light-emitting
chip can be overcome; therefore, the heat dissipation efficiency is greatly enhanced, the space structure of the lamp is compressed, the heat dissipation requirements of the LED lamps of different powers are satisfied and the service life of the
LED lamp is effectively prolonged; and by utilizing the angle-adjustable light-gathering tile, the
light irradiation range can be effectively expanded and the utilization efficiency of the light can be enhanced. The
LED lamp provided by the invention is particularly suitable for a roadway lighting lamp or a ceiling type lighting lamp and is easy to popularize.
