When the heat dissipation assembling structure of the LED street lamp is in use, an LED light-emitting assembly is assembled according to road conditions, the requirements for power and the technical scheme. The baffles are added to two ends of each LED light-emitting assembly so that one or a plurality of LED light-emitting assemblies form a lamp cap, a light-emitting strip is arranged reasonably, and the strength of cross-ventilation is reinforced during work. Dust and sundries which are accumulated in a lamp holder heat-dissipation groove are eliminated under the flushing effects of natural air or rain water, the heat dissipation effect of a heat dissipation base is achieved and enhanced, and the heat dissipation assembling structure of the LED street lamp has the advantages of being low in cost, simple in assembling process, flexible in light distribution, good in heat dissipation effect and the like.
Description
Technical field
The present invention relates to the LED technical field of lamps, the LED road lamp cooling package assembly of specifically a kind of good heat dissipation effect, long service life.
Background technology
As everyone knows, constantly bringing forth new ideas and develop along with science and technology.Semiconductor lighting replaces conventional light source the most fully with high-power LED light source; Mainly being formed by combining of high-power LED street lamp radiator, heat-conducting cream, LED illuminator, secondary optics luminous intensity distribution reflector, protective cover; The working junction temperature of high-power LED light source performance and life-span and the led light source relation of being inversely proportional to therefore in use, needs supporting good heat dissipation design to reduce the led light source operating temperature and then reduce its junction temperature; Road lamp needs good seal to reach the water proof and dust proof effect under the rugged environment out of doors; This closed environment is unfavorable for the heat radiation of led light source, thereby has influence on the performance and the service life of LED street lamp, and the radiator of existing high-power LED lamp is generally whole real core body; Radiator external " the fish gill " shape fin, its deficiency are that weight is big, the spray takes material, radiating effect difference etc.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of good heat dissipation effect, easy to assembly, flexible luminous intensity distribution are provided, adapt to the LED road lamp cooling package assembly that road lighting requires.
The present invention solves the problems of the technologies described above the technical scheme of being taked:
A kind of LED road lamp cooling package assembly is characterized in that being made up of baffle plate and heat-radiating substrate, and it is half-cylindrical that heat-radiating substrate is; The cambered surface of heat-radiating substrate is provided with vent rib upwards; The plane of heat-radiating substrate is provided with the groove that LED light-emitting section, lens and glass capping plate are installed, and heat-radiating substrate is cavity-like, is provided with the heat conduction floor in the heat-radiating substrate cavity; Heat conduction floor to major general's heat-radiating substrate internal cavity is separated into two independences or plural space, to form the ventilation and heat passage.
The present invention can be provided with vent rib at the top of heat-radiating substrate, and vent rib is on the curved surfaces that strip is evenly distributed on heat-radiating substrate, the good heat dissipation effect of vent rib.
When the present invention uses,, confirm the number of required LED light-emitting section according to road conditions and power needs; Be assembled into the LED luminescence component according to technique scheme then, the technology of LED luminescence component is: the LED light-emitting section is fastened in the groove of heat-radiating substrate, lens are fixed on the LED light-emitting section; Glass capping plate is fixed on and is combined into the LED luminescence component on the heat-radiating substrate, and LED luminescence component two ends in addition plate washer are fixed one or more LED luminescence components and formed lamp holder with screw, like this LED street lamp of production; Its light-emitting section connection and reasonable arrangement; Brightness that lamp holder produced and spot pattern are foundation with road lighting demand on the spot, can adapt to road conditions needs on the spot well; Radiator of the present invention changes to inner vertically disposed air channel; Heat-radiating substrate is an individual devices, can pass through an extrusion modling, strengthens cross-ventilation intensity when so both having helped product work; Help again the dust and the foreign material that overstock in the lamp socket radiating groove are removed under natural wind or rainwash effect; Thereby realize and strengthened the heat radiation function of heat dissipation base, have low, the simple for assembly process practicality of cost, luminous intensity distribution flexibly, advantage such as good heat dissipation effect.
