Description
[technical field]
The utility model relates to the heat sink technology field, particularly a kind of LED street lamp heat radiator.
[background technology]
Street lamp is the important component part of city illumination, traditional street lamp often adopts high-pressure mercury lamp, the shortcoming that its light efficiency of high-pressure mercury lamp is low has caused the huge waste of the energy, therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the street lamp of environmental protection has a crucial meaning to city illumination is energy-conservation.
Great power LED (Light Emitting Diode, what light emitting diode) street lamp was different with conventional high-pressure sodium street lamp is, the efficient white light-emitting diodes that the light source of high-power LED street lamp adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder, have efficient, safety, energy-saving and environmental protection, distinct advantages such as the life-span is long, response speed is fast, colour rendering index height, can be widely used in city illumination.
But the temperature of LED street lamp is the main factor that influences its light decay, and simultaneously, temperature also influences its service life.
[utility model content]
In order to solve existing technical problem, the utility model provides a kind of LED street lamp heat radiator, and it adopts the radiation radiating fin to be arranged on the substrate, makes good heat dissipation effect, thereby prolongs the service life of LED street lamp.
The utility model solves existing technical problem, a kind of LED street lamp heat radiator is provided, it comprises heat radiation main body that is used to absorb LED module heat and the supporting seat that links to each other with described heat radiation main body, this LED street lamp heat radiator comprises radiating fin, and described radiating fin radiation is distributed on the described heat radiation main body.
The utility model further improves:
Described supporting seat is a stop sleeve, and this stop sleeve is fixed on described a plurality of radiating fin.
The bearing of trend of described stop sleeve and plane, described radiating fin place are parallel to each other.
The lampshade installation portion of button in two relative edges of described heat radiation main body are provided with.
In described lampshade installation portion, the waterproof mounting groove is set.
This LED street lamp heat radiator comprises heat-conducting substrate, and described heat-conducting substrate and described heat radiation main body are fitted.
The LED module is set on described heat-conducting substrate.
Reflective mirror is tiltedly established in periphery at described heat-conducting substrate.
