The notch of described power supply tank is embedded with a groove lid, the both sides outer wall of described power supply tank and groove lid are provided with multiple fin.
It is preferable over: the lamp bar pedestal and the fin that are positioned at described power supply tank both sides are symmetrical, constituting circular trace in cross section on described heat dissipation base between the end points of each described fin, two described lamp bar pedestals are corresponding in two adjacent quadrant scopes respectively.
It is preferable over: on each described lamp bar pedestal, the another side corresponding with described lamp bar tank is provided with radiating fin.
It is preferable over: described power supply tank, connecting plate, lamp bar pedestal, the fin being positioned on the outer wall of power supply tank both sides and radiating fin are that aluminum alloy material is one-body molded.
It is preferable over: each described lamp bar tank is all covered with lamp bar cover, described lamp bar tank is T-slot, described LED light-emitting section is the bar shaped aluminium base of LED lamp bead of being sticked, described bar shaped aluminium base plug-in card is in described T-slot, the both sides being positioned at described lamp bar tank on described lamp bar pedestal offer draw-in groove respectively, the described lamp C-shaped channel-shaped of bar cover, and the notch both sides inwall of C-shaped channel shape is all convexly equipped with card rib, two described card ribs inside described lamp bar cover can distinguish corresponding plug-in card in the draw-in groove of described lamp bar pedestal both sides.
It is preferable over: said two end cap is provided with the power connector for connecting external power source.
Compared with prior art, the beneficial effects of the utility model are:
One, on described power supply tank, it is fixedly connected with two lamp bar pedestals by connecting plate, and the light-emitting window correspondence direction on two lamp bar pedestals is in the angle more than 10 degree, less than 90 degree, the direction of illumination of the LED light-emitting section on said two lamp bar pedestal can be respectively radiated to both direction whereby, and then increase illumination range;
Two, the outline of the cross section of heat dissipation base is rounded, and two described lamp bar pedestals are arranged within the scope of two adjacent quadrants in corresponding circular scope, therefore described LED light-emitting section is distributed in the cambered surface of circular in cross-section, and then the range of exposures of LED light-emitting section can be increased, and make the light efficiency after two adjacent LED luminous lamp strip splits more uniform;
Three, the heat on LED luminous lamp strip dispels the heat either directly through lamp bar pedestal, connecting plate and radiating fin, the heat produced on described power-supply controller of electric is dispelled the heat by the fin on power supply tank and groove lid, therefore LED luminous lamp strip and power-supply controller of electric dispel the heat to the air contact of surrounding respectively, area of dissipation is wider, better heat-radiation effect, will not intersect transmission.
