Led light source is a kind of electric energy to be converted into the solid-state semiconductor device of visible light, has following characteristics as the lighting source of a new generation:
Led light source power consumption is low, and luminous efficiency is high, and photoelectric transformation efficiency generally can reach more than 20%, improves 4 times than conventional incandescent, is 2 times of power saving fluorescent lamp;
The led light source life-span is long: because led light source is the solid cold light source; Light source inside does not have loosening part; Do not exist filament light-emitting to be prone to shortcomings such as burning, heat deposition, light decay, condition following service life of rated voltage and rated frequency more than 50,000 hours, longer more than 10 times than the conventional light source life-span;
The led light source environmental benefit is good: led light source in use can not produce harmful substance; Do not have ultraviolet ray and infrared ray, little, the no stroboscopic of dazzle in the spectrum yet, can not cause optical pollution, and discarded object is recyclable; Light source inside does not contain mercury element, belongs to typical green illumination light source;
The led light source stable performance, can be under-30 ℃～50 ℃ conditions long-time operate as normal can satisfy the normal lighting demands in overwhelming majority area.
Because above advantage; Led light source is got for existing conventional light source just gradually, but owing to effective operation of led light source necessarily requires lamp pearl junction temperature is controlled in the certain temperature range, along with the rising of lamp pearl junction temperature; Luminous efficiency, lamp pearl life-span sharply reduce, and the light decay phenomenon is serious.And great power LED integrated optical source can cause great amount of heat to pile up the extensive integrated bigger light emitting source that forms in the circuit board of single led light source thus, is accompanied by the increase of integrated LED lamp pearl power, has a strong impact on the luminescent properties of led light source.
The structural design of existing LED street lamp mainly is to adopt the agent structure of die casting aluminum hull spare as light fixture, simultaneously with its heat radiation main body of light fixture as a whole.But be accompanied by the continuous increase of LED street lamp power; Integrated LED road-light light-source hot spot effect highlights day by day; Merely rely on the conventional road lamp structural design of the heat dispersion that increases lamp casing heat-sinking capability expectation raising street lamp to run into bottleneck; The transitional street lamps structural design possibly satisfy the designing requirement of high-power integrated LED street lamp hardly, and existing radiating mode can not effectively utilize the maximum heat-sinking capability of lamp housing, has caused the waste of resource.
Summary of the invention
The utility model provides a kind of LED street lamp, especially is fit to the high-power LED street lamp.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of LED street lamp comprises supporting substrate, LED lamp pearl, LED power supply and heat abstractor, and described heat abstractor, LED lamp pearl, LED power supply all are fixed on the supporting substrate.
Further, described heat abstractor comprises heat-transfer arrangement, radiating fin group and LED lamp pearl fixed structure.
Further, described heat-transfer arrangement is that general heat pipe or loop circuit heat pipe are bent into the shape that is beneficial to heat radiation.
Further, described general heat pipe or loop bend pipe are bent into snakelike.
Further, said LED lamp pearl fixed structure connects LED lamp pearl and heat-transfer arrangement.
Further, described LED lamp pearl fixed structure is processed by Heat Conduction Material.
Further, described high-efficiency heat conduction material is a copper.
Further, on the described supporting substrate reinforcement is arranged.
Further, on the described supporting substrate heat dissipation ventilation hole is arranged.
Further, described LED street lamp also comprises the protection housing, and described protection housing and supporting substrate form a hermetic cavity body, on the described protection housing heat dissipation ventilation hole are arranged.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, and the high-power LED street lamp that the utility model provided, it is flexible to have perfect heat-dissipating, compact conformation, moulding, has less advantages such as light fixture weight simultaneously.

The specific embodiment
Below in conjunction with this exemplary construction and accompanying drawing the utility model is done further elaboration: can find out by Fig. 1; This instance forms an airtight space by supporting substrate and containment vessel body; Supporting substrate is as the carrier as whole lamp part, and other all devices all are placed in the cavity of being made up of supporting substrate and protection housing.
Fig. 2 is the part parts broken away view of an instance of the utility model, can be found out by Fig. 2, and the effect of protection housing is the impact damage that protection heat abstractor, great power LED power supply avoid external object.The material of protection housing can be chosen as cast aluminium, fiberglass, plastics, both can alleviate the weight of whole LED street lamp, also can strengthen radiating effect simultaneously.The protection housing is designed with the heat dissipation ventilation hole, helps the air good flow, strengthens the heat exchange effect.The design of the external type of containment vessel can freely design according to the moulding needs, light fixture to beautify the moulding free degree big.Material can adopt easy-formation materials such as metal, fiberglass or plastics; Processing mode can adopt modes such as cast aluminium, injection moulding or punching press to solve; When the protection housing is the highly heat-conductive material metal, can partly contact with heat abstractor by the design protection housing, bear the radiating requirements of a part.Supporting substrate is provided with heat abstractor, power supply, lamp pearl, reaches lamp pearl fixed structure, selects two high-power integrated LED lamp pearls in this example for use, is supplied power respectively by two great power LED power supplies.Lamp pearl fixed structure is used for fixing the high-power lamp pearl, and simultaneously lamp pearl fixed structure is processed by the high-efficiency heat conduction material, includes but not limited to the material of metal such as copper, aluminium, pottery or nonmetal high thermal conductivity coefficient.The utility model adopts copper to be used for improving the heat conductivility of lamp pearl fixed structure as the material of lamp pearl fixed structure.The effect of heat-transfer arrangement is to connect high-power integrated LED lamp pearl and heat-transfer device by lamp pearl fixed structure, and the heat that the high-power integrated LED lamp pearl is given out conducts to heat-transfer device.Be designed with the installation and combination structure of other necessary assembly of light fixture on the supporting substrate simultaneously, like the installing mechanisms such as screwed hole of light fixture fixed installation structure.
