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 light fixture with heat transfer structure, comprises a lampshade 1, a LED lamp group 2 and a power connection 3; Wherein:

Described lampshade 1 is made into integration by the good material of thermal conductivity, 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, with by with the contacting of described interlayer 11, and the heat that light emitting diode 21 is produced can be given heat conduction, and heat is disengaged by each fin on lampshade 1 body 10 12.

Described power connection 3 is provided in a side of on second space 101 of lampshade 1 body 10, and has an outstanding Plug Division 30 outside, described Plug Division 30 front ends are equipped with pin 300, there is a control circuit board 31 rear end then build-in, has single or multiple electronic building brick 32 on the described control circuit board 31, in order to changing alternating current into direct current, and electronic building brick 32 also can produce heat.The utility model main purpose promptly is: by above-mentioned lampshade 1, except helping also to provide the heat radiation of the electronic building brick 32 on the described control circuit board 31 required simultaneously light emitting diode 21 dispels the heat; Wherein, the interlayer 11 of lampshade 1 is equipped with the heat-conducting block 13 more than one or towards 101 places, second space, and present embodiment is one, described heat-conducting block 13 is to be formed with a thermal conductive surface 130 with respect to aforementioned electronic assembly 32 places, with and electronic building brick 32 contact and be convenient to carry out conduction of heat, and also can on described thermal conductive surface 130, attach heat-conducting mediums (figure slightly) such as one deck heat conduction pad or coating one deck heat-conducting cream, to fill up crack, space or tolerance etc. between 32 of described thermal conductive surface 130 and the electronic building bricks, in order to do increasing contact effect person; So, the heat that electronic building brick 32 is produced can be by contacting with the thermal conductive surface 130 of heat-conducting block 13, and conduct on lampshade 1 body 10 each fin 12 outward by heat-conducting block 13, make each fin 12 can not only help light emitting diode 21 to dispel the heat, also can provide the heat radiation of electronic building brick 32 of control circuit board 31 required.
