End in contact, the other end of second heat sink stretch out fixed plate radiating.
Further improve, second heat sink includes connecting portion and radiating part；The connecting portion and the described first radiating
Plate is connected, and the radiating part is horizontally disposed outside the fixed plate.
Further improve, the connecting portion Wei " ╲ " shape, the radiating part is "-" shape.
Further improve, the second heat sink described in polylith is distributed in circular.
Further improve, the LED chip is plugged in the PCB substrate；With the heat pipe of the LED chip homonymy
It is pressed in by the LED chip in the PCB substrate.
Further improve, the LED chip includes illuminating part, base and pin；The LED chip is inserted by the pin
It is connected in the PCB substrate；The pin is " ┌ " shape.
Further improve, the base extends limited location towards the both sides of the heat pipe positioned at the PCB substrate homonymy
Block；Wherein the limited block of side is in contact with the PCB substrate and is connected by viscose glue.
Further improve, a reflector is housed on each described base, the luminous site is in the reflection
In cup.
The utility model is respectively arranged with heat pipe in PCB substrate both sides, and heat pipe will be warm caused by LED chip and PCB substrate
Amount passes to the first heat sink for being covered in above heat pipe, and the heat transfer on the first heat sink give the second heat sink, and second is scattered
One end of hot plate is stretched out fixed plate and radiated, the second heat sink by the heat inside LED by heat pipe, the first heat sink and
Second heat sink is transferred in environment, because the temperature in environment is greatly lowered compared with the temperature in lamp, increases the drive of radiating
Power, therefore utility model has good radiating effect, can fast and effeciently disperse the heat inside lamp, improve this reality
With new using effect, extend service life of the present utility model.
