Abstract
The utility model discloses a light-emitting diode (LED) lamp with an air cooling heat sink. The LED lamp with the air cooling heat sink comprises a reflector shade, a flat-panel LED light emitting unit installed at the bottom of the reflector shade, a light source installed fixedly on the surface of the flat-panel LED light emitting unit, and a circuit controller installed on the reflector shade. The LED lamp with the air cooling heat sink is characterized in that a fixed heat sink is installed on the surface of the outer side of the flat-panel LED light emitting unit, and the fixed fan heat sink is installed on the surface of the heat sink and integrated with a fan to form the air cooling heat sink. According to the LED lamp with the air cooling heat sink, the air cooling heat sink is installed outside the flat-panel LED light emitting unit, and forces large quantity of air to be sucked away through the air cooling heat sink. Therefore, working temperatures of the flat-panel LED light emitting unit and the circuit controller are enabled to be further decreased, and the service life of the LED lamp is thus greatly prolonged.
Description
Technical field
The utility model relates to a kind of LED bulb, especially a kind of LED lamp with great heat radiation effect new structure.
Background technology
Along with people strengthen the idea of energy savings, the LED lighting engineering is owing to have high energy efficiency, long advantage of life-span, social broad development and application have been obtained in recent years, replaced gradually incandescent lamp, fluorescent lamp or even electricity-saving lamp, LED has been made into common lamp shape and structure so that compatible with existing ordinary lamps at present.But the problem that this structure need to solve is the heat dissipation problem that causes when adopting the high-power LED illumination, because the impact of the working life of operating temperature LED is very large, therefore must take effective radiator structure to reduce the operating temperature of LED lamp, especially LED luminescence unit and circuit controller temperature make the longer service life of whole LED lamp.
Summary of the invention
The purpose of this utility model provides a kind of LED lamp, has more effectively radiator structure, so that the operating temperature of planar LED luminescence unit and circuit controller further reduces, has prolonged service life greatly.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED lamp with air-cooled radiator, comprise lampshade, the bottom of lampshade is provided with the planar LED luminescence unit, surface at the planar LED luminescence unit is fixed with light source, lampshade also arranges circuit controller, it is characterized in that, on the described planar LED luminescence unit outer surface fixing fin is housed, the fixing fan of installing on the surface of fin, fin and fan are integrated, and form an air-cooled radiator.
As the further design to the aforementioned techniques scheme: the fin that described air-cooled radiator is provided with is provided with at least six air vent 1.
As the further design to the aforementioned techniques scheme: described with at least six air vents 2 corresponding to the same with fin air vent 1 aperture also are set on the plane of planar LED luminescence unit.
As the further design to the aforementioned techniques scheme: be equiped with a reflecting metal sheet between described air-cooled radiator and the planar LED luminescence unit, be covered with cellular through hole on this reflecting metal sheet.
The beneficial effects of the utility model are: the beneficial effects of the utility model are: the heat that led light source produces is mainly from the electronic devices and components in led light source itself and the circuit controller, the heat that therefore the two must be produced is taken away rapidly, wherein fin has played certain radiating effect, and this practicality also arranges fan-shaped in fin surface and becomes air-cooled radiator, can force so a large amount of hot-airs by opening being discharged the lamp body outside, the electronic devices and components temperature in planar LED luminescence unit and the circuit controller is reduced.Said structure can effectively increase the heat dispersion of radiator, so that the operating temperature of planar LED luminescence unit and circuit controller further reduces, has prolonged service life greatly.

Fig. 2 is the utility model embodiment LED modulated structure decomposing schematic representation.
The specific embodiment
Embodiment 1
The utility model embodiment 1, such as Fig. 1 and shown in Figure 2, a kind of LED lamp with air-cooled radiator of describing comprises lampshade 1, and the bottom of lampshade is provided with planar LED luminescence unit 3, be fixed with light source 2 on the surface of planar LED luminescence unit, lampshade also arranges circuit controller 4, on the described planar LED luminescence unit outer surface fixing fin 5 is housed, the fixing fan 6 of installing on the surface of fin, fin and fan are integrated, and form an air-cooled radiator 7.The fin that described air-cooled radiator is provided with is provided with at least six air vent 18.Described with at least six air vents 29 corresponding to the same with fin air vent aperture also are set on the plane of planar LED luminescence unit.Be equiped with a reflecting metal sheet 10 between described air-cooled radiator and the planar LED luminescence unit, be covered with cellular through hole 11 on this reflecting metal sheet.This is with the LED lamp of air-cooled radiator, realized by the formed airflow of air-cooled radiator, again by corresponding cross-ventilation through hole and cellular through hole, make in the lamp body Air Flow more smoothly, thereby both heats that produce of electronic devices and components in led light source itself and the circuit controller are taken away rapidly.So that the operating temperature of planar LED luminescence unit and circuit controller reduces effectively.
The above only is preferred embodiment of the present utility model, is not technology contents of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
