Described heat pipe contains the liquid that is used to absorb and conduct heat for the metal catheter of sealing in the pipe, described heat pipe has one at least, and every heat pipe has at least an end to stretch out outside base plate.
Described heat pipe is in-line and has 14.
Described base plate is a rectangle, and described heat pipe is symmetrically distributed in the both sides of base plate, and an end of heat pipe is welded on the base plate, and the other end stretches out outside base plate.
The described radiating fin that is arranged on the heat pipe is a plurality of, and each fin is long slab shape and offers patchhole corresponding to the external part of heat pipe that this radiating fin interts evenly and at intervals and is welded on the external part of above-mentioned heat pipe.
The cross section that the described radiating fin that is arranged on the base plate is a plurality of and each fin is L-shaped, and the welding of this radiating fin and base plate is fixed into the rectangle fins group, and the length of " L " shape holds outward that hull shape becomes opening.
Described heat abstractor closely contacts with aluminium base by base plate and is fixing.
Described power pack is installed on the base plate of outer casing back.
Also comprise a device that is used to carry the LED light fixture that is connected with described LED light fixture.
The utility model compared with prior art its beneficial effect has: since heat abstractor by base plate, be arranged on heat pipe and the radiating fin on the base plate, the radiating fin that is arranged on the heat pipe is formed, and all radiating fins all outward shell be formed with opening, be convenient to the cross-ventilation heat radiation, so the utility model volume is little, in light weight, good heat dissipation effect, can solve the heat dissipation problem of 200W LED light fixture.In environment temperature is below 35 degrees centigrade the time, and LED substrate aluminium base temperature is no more than 65 degrees centigrade.Can prolong LED light fixture service life like this.
