The utility model to achieve these goals, adopt following technical scheme: a kind of LED street lamp substrate, be by: substrate, isosceles trapezoid cambered surface, inclined-plane, oval reinforcement, circular reinforcement, sphere shape light loophole, strip louvre, strip permeable hole, light source mounting seat, power supply firm banking, install fixing hole form; The middle part of substrate front side side arranges permeable hole group, opposite side arranges concave surface, described concave surface arranges inclined-plane by isosceles trapezoid cambered surface two ends and forms, isosceles trapezoid cambered surface arranges oval reinforcement in front, the center of oval reinforcement arranges circular reinforcement, in circular reinforcement, sphere shape light loophole is set, between circular reinforcement and oval reinforcement, at least ten strip louvres is set in divergent shape, in inclined-plane, two sides, at least five strip louvres be parallel to each other are set; Arrange light source mounting seat between the both sides of substrate back divergent shape strip louvre and substrate edges, be symmetrical arranged two pairs of power supply firm bankings between substrate back inclined-plane and permeable hole group, the edge of substrate is uniformly distributed at least four and installs fixing hole.

Described substrate is curved panel.

In described concave surface, the radian of isosceles trapezoid cambered surface is equal with the radian of substrate.

Described permeable hole group is set up in parallel by least two group leader's bar shaped permeable holes and forms, and often group is made up of at least three parallel to each other settings of strip permeable hole.

Described circular reinforcement and sphere shape light loophole are concentric circles.

The beneficial effects of the utility model are: the heat that LED light source of the present utility model comes out in the course of the work is outwards shed by louvre, can the temperature of effective control LED module, good heat dissipation effect, ensure its service life, integration degree is high, and cost is lower, and secondary optical design is easy, convenient processing and maintenance, the utilization rate of abundant raising light, lampshade and substrate can adopt partial installation, and adopt waterproofing design, good water-proof effect, resistance to oxidation, corrosion-resistant, be convenient to safeguard, can Long-Time Service, not fragile.

Housing of the present utility model and substrate are all adopted as aluminium alloy heat sink, and radiating effect is remarkable, and area of dissipation is large, good heat dissipation effect, effectively promote LED electrical power module heat dissipation, and simple and compact for structure, and volume is little; Aluminum alloy material has that thermal conductivity is good, thermal resistance is high, rapid heat dissipation, lightweight, price is lower (compared to materials such as copper), the feature of good weatherability (compared to materials such as PC), good heat dissipation effect, can manufacturing cost be reduced, long service life, between adjacent heat radiation assembly, there is gap, heat radiation is corresponding to be arranged, make air form convection current, strengthen radiating effect, inner heat is outwards shed in time, make high-powered LED lamp not easily aging distortion, effectively extend its service life.
