Abstract
The utility model provides an LED streetlamp radiator which comprises a plane which is connected with a PCB board provided with an LED lamp and another plane provided with radiating fins, wherein the radiating fins are arranged on two sides, and the middle of the plane is provided with a bracket for installing a lamp rod fixing piece of an LED streetlamp, the bracket is provided with a plane for contacting with the lamp rod fixing piece, and the radiating fins are symmetrically arranged on the two sides of the bracket, and the heights of the radiation fins on both sides are different, and the radiating fins are heightened in turn from outside to inside, the cross section of each radiating fin is trapezoidal, and the root portion of each radiating fin is larger than the tip portion thereof. The utility model provides the technical scheme that the distances among the radiating fins of the radiator are gradually widened from the root portion to the tip portion, which is beneficial for air to flow, and improves the radiation effect, simultaneously, the radiating fins can contact with the lamp rod fixing piece in larger area, which greatly increases the radiation area of the radiator, and accelerates the radiation speed.
Description
Technical field
The utility model relates to the heat abstractor of lighting, particularly utilizes the LED lamp to make the radiator of the LED street lamp of lighting source.
Background technology
Compare with traditional street lamp, the characteristics that the LED street lamp that utilizes the LED lamp to do light source has not only that colourity is good, non-maintaining, the life-span is long, and the more important thing is more energy-conservationly than conventional road lamp, be a kind of communal facility of energy-conserving and environment-protective.As the LED street lamp, heat radiation is technological difficulties, and the LED street lamp on the market has all added radiator now, and these radiators are close to the pcb board that the LED lamp is installed, and a large amount of heats that the LED lamp is distributed conduct in the ambient airs, take away by cross-ventilation.Radiator of the prior art is of a great variety, all be utilize metal particularly aluminium alloy extrusions make, in the one side of section bar the fin of some convex is set, to increase the area that contacts with air, but, space between these fin is very dark, adds that the distance between each fin is little, therefore, after heat is delivered in the air in the gap, if do not add the external force that ventilates, such as blowing air is wherein blown away, its heat radiation fruit will be had a greatly reduced quality.All be that aluminum alloy materials is made as the fixing lamp stand fixture itself of street lamp and lamp stand in addition, it itself also is a kind of good conductor of heat, contact area between radiator of the prior art and the lamp stand fixture is little, can not utilize the lamp stand fixture that heat is led away fully.
Summary of the invention
Dark for the gap between the fin in the radiator that overcomes LED street lamp in the prior art, be difficult for automatically hot-air being exchanged away the deficiency that influences radiating effect and do not make full use of the heat conduction of lamp stand fixture, the utility model provides a kind of LED street lamp heat radiator.
The utility model in order to realize the technical scheme that its technical purpose adopts is: a kind of LED street lamp heat radiator, comprise the plane and the fin that are connected with the pcb board that the LED lamp is installed, described fin is located at the both sides of radiator, the centre of radiator is provided with the support of the lamp stand fixture that is used for installing the LED street lamp, and described support is provided with and is used for the plane that contacts with described lamp stand fixture.
In the technical solution of the utility model, distance between each fin in the radiator from the root to the tip gradually broadening help air and flow, improve radiating effect, contact in large area with the lamp stand fixture simultaneously, increase the area of dissipation of radiator greatly, accelerated the speed of heat radiation.
Below in conjunction with the drawings and specific embodiments the utility model is done comparatively detailed description.
Description of drawings
Accompanying drawing 1 is the utility model embodiment 1 schematic perspective view.
Accompanying drawing 2 is the utility model embodiment 1 profile.
Among the figure: 1, plane, 2, fin, 3, support, 4, link slot.
The specific embodiment
Embodiment 1, as Fig. 1, shown in Figure 2: a kind of LED street lamp heat radiator, comprise plane 1 that is connected with the pcb board that the LED lamp is installed and the another side that is provided with fin 2, fin was located at the radiator both sides in 2 minutes, be provided with the support 3 of the lamp stand fixture that is used for installing the LED street lamp in the middle of the radiator, support 3 is provided with and is used for the plane that contacts with described lamp stand fixture, when mounted, can contact in large area with the lamp stand fixture, the lamp stand fixture is joined in the radiator, radiator in the present embodiment is that aluminium alloy extrusions adopts technologies such as aluminium extruded technology and five metals metal plate punching to make, and the lamp stand fixture also is to be made by aluminium alloy extrusions, the surface is all passed through special anode and is handled, and has good heat-conducting, a large amount of heat that the LED lamp produces can be distributed rapidly.Simultaneously, fin 3 is symmetricly set on the both sides of support 3, and the height of each fin 2 on every limit has nothing in common with each other, and increases arrangement from outside to inside successively, and the cross section of each fin 2 is trapezoidal.The root of each fin 2 is greater than the tip.Like this, each fin 2 ambient air can both exchange with outside air and form convection current, simultaneously, fin 2 is made the shape that root is big, the tip is little, makes big above little apart from root between each fin 2, helps circulation of air, helps the heat convection current.In addition in the present embodiment, for the LED lamp is installed better, 1 both sides, plane that connect at the pcb board of the installation LED of radiator lamp are provided with the link slot 4 that pcb board is installed.
Claims (3)
1. LED street lamp heat radiator, comprise the plane and the fin that are connected with the pcb board that the LED lamp is installed, it is characterized in that: described fin (2) divides the both sides that are located at radiator, the centre of radiator is provided with the support (3) of the lamp stand fixture that is used for installing the LED street lamp, and described support (3) is provided with and is used for the plane that contacts with described lamp stand fixture.
2. a LED street lamp heat radiator according to claim 1, it is characterized in that: described fin (2) is symmetricly set on described support (3) both sides, and the height of each fin (2) on every limit increases arrangement from outside to inside successively, and the cross section of each fin (2) is trapezoidal.
