The specific embodiment

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.

See also Fig. 1 to Fig. 3, the utility model provides a kind of LED light fixture, comprises a lampshade 1, a LED lamp group 2 and a power connection 3; Wherein:

See also shown in Figure 3, described lampshade 1 can be made into integration by the good material of thermal conductivity, described Heat Conduction Material is an aluminium etc., it has a cup-shaped body 10, be hollow in the described body 10, and the portion middle section has been horizontally set with an interlayer 11 within it, so that described body 10 inner area are divided into one first space 100 and one second space 101.In addition, locating around described body 10 sides is to be provided with outward extending complex cooling fin 12, in order to provide heat radiation required.

Described LED lamp group 2 is located in first space 100 of above-mentioned lampshade 1 body 10, and comprise a circuit board 20, at least one light emitting diode (LED) 21 that is located on the described circuit board 20, one is located at the outer reflection shield 22 of described light emitting diode 21 peripheries, and one be installed on the described reflection shield 22 and for the lens 23 of light emitting diode 21 towards its projection, and described circuit board 20 back sides promptly are attached on the interlayer 11 of lampshade 1 body 10, and at described interlayer 11 towards 100 places, first space, be equipped with first heat-conducting block 110 that is attached to light emitting diode 21 bottoms, with make described light emitting diode 21 can by with the contacting of described first heat-conducting block 110, and can make the heat that self produces adsorbed by lampshade 1 body 10, and heat is conducted to each fin 12 place on lampshade 1 body 10 by interlayer 11,, heat reaches the radiating requirements of light emitting diode 21 so that being disengaged.
