Abstract
The utility model relates to a Light-Emitting Diode (LED) lamp, and particularly to an active radiating high-power LED lamp, which comprises a lamp holder, wherein the lamp holder is connected with a lamp socket, and a circuit board connected with the lamp holder is arranged in the lamp socket; the active radiating high-power LED lamp is characterized in that: the lamp socket is arranged at the upper end of a lamp shade; a circuit substrate, which is connected with the circuit board, is arranged at the lower end of the lamp shade; the circuit substrate is equipped with an LED light source; a radiator is arranged in the lamp shade; and a fan, which is connected with the circuit board, is arranged above and/or below the radiator. The active radiating high-power LED lamp combines the radiator with the fan, and the radiator can be arranged in the lamp shade rather than be directly exposed so as to avoid influence to radiation and to increase radiation effect, so that completeness of the external structure of the lamp is ensured; in addition, the size and the rotation speed of the fan can be set according to different heating values, thereby realizing active radiation, reducing temperature of the work environment of the LED lamp, and prolonging the service life of the LED lamp.
Description
Technical field
The utility model relates to a kind of LED light fixture, especially a kind of built-in active heat removal high-powered LED lamp.
Background technology
The LED lamp of existing alternative common bulb, for example bulb lamp generally all connects a radiator in order to dispel the heat; Outside existing bulb lamp radiator generally all is exposed to, and fin generally comprises many radiating fins, influences the overall appearance of light fixture; And when using a plurality of great power LEDs as light source; Only depend on the passive heat radiation of radiator often can not dispel the heat fast, the gathering of heat causes its brightness of wearing out, make of LED to decay rapidly easily, has reduced the service life of product.
Summary of the invention
The purpose of the utility model provides complete, the high-powered LED lamp that can active heat removal of a kind of external structure.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a lamp holder; Lamp holder connects a lamp socket, is provided with the circuit board that is connected with lamp holder in the lamp socket, and lamp socket is installed on the upper end of a lampshade; The lower end of lampshade is provided with the circuit base plate that links to each other with circuit board; Described circuit base plate is provided with led light source, is provided with radiator in the described lampshade, and the top of described radiator and/or below are provided with the fan that is connected with circuit board.
Preferably, the lamination shape radiator of described radiator for stacking together by a plurality of fin, described each fin is provided with one or more perforates, and after a plurality of fin stacked, one or more gas channels were formed in the one or more perforates on the fin.
Preferably, described gas channel is straight-through shape or spirality.
Preferably, described circuit base plate is provided with a diffuser outward.
Preferably, described radiator is the tubulose polyhedral structure of hollow, is provided with radiating fin in the described hollow part, and described led light source is located on the outside a plurality of planes of radiator.
The active heat removal high-powered LED lamp of the utility model is through the combination of radiator and fan; The radiator that is can be arranged in the lampshade and not influence heat radiation, need not radiator be directly exposed to external raising radiating effect, thus the external structure integrality of the light fixture that guarantees; And the size and the rotating speed of fan can be set according to the caloric value difference; Realize active heat removal, reduce the operating ambient temperature of LED, prolong the service life of product.
