The link of described complex root heat-conducting piece is connected in connecting portion, and free end is positioned at lampshade 2/3rds highly to be located, and the lampshade top is bigger to the illuminating effect influence, so heat-conducting piece does not extend to the lampshade top, avoids too much dim spot.
Described heat-conducting piece is distributed on the lampshade inwall, has both reduced the influence of heat-conducting piece to illuminating effect, heat evenly can be conducted to lampshade again.
Described lamp socket comprises metal heat sink, further increases radiating effect; Lateral surface one end of described radiator connects lampshade, and other end sidewall is provided with uniform vertical radiating fin.Both be convenient to radiator heat had been distributed by self, and also be convenient to conduct to lampshade and distribute, the good heat dissipation effect of rational in infrastructure and radiator.
Described connecting portion and radiator one end are spirally connected, and described lamp socket comprises the lamp holder that is arranged on the radiator outer end, and radiator is connected by a lamp holder connector with lamp holder.Fixed forms such as welding relatively, riveted joint, installation, convenient disassembly are convenient to maintain and replace.
Described heat-conducting piece surface scribbles reflective material layer, reduces the obstruction of heat-conducting piece to the light conduction efficiency, desalination dim spot phenomenon.
Described radiator is the hollow cylindrical structure, and driver is housed in it, and described driver one end lead connects the LED substrate, and other end lead connects lamp holder.Can make full use of the function of radiator, make its outside heat radiation, inside constitutes spatial accommodation, reduces the volume of LED lamp.LED substrate and driver are integrated in the light fixture simultaneously, rational in infrastructure, easy to use.
Scribble heat-conducting medium in the gap of described connecting portion and radiator.Heat-conducting medium can be heat-conducting silicone grease or its similar substance.Increase the two contact-making surface and heat-conducting effect.
The LED lamp of the built-in heat-conducting piece of a kind of lampshade that the present invention obtains, by heat-conducting piece the heat that LED sent effectively is transmitted on the lampshade from the LED substrate, extended the radiating surface of LED lamp, the contact-making surface that makes full use of the lampshade and the external world distributes heat fast, promoted the function of lampshade, improve the heat dispersion of LED lamp effectively, thereby can save radiator or reduce the size of radiator, reduced the weight and the cost of LED lamp.
