Description
Technical field
The utility model belongs to LED technical field of lamps, is specifically related to a kind of LED lamp.
Background technology
LED is semiconductor light-emitting-diode, LED lamp is used high brightness white light-emitting diode illuminator, light efficiency is high, little power consumption, life-span are long, easy to control, non-maintaining, safety and environmental protection, and the various public places such as applicable family, market, bank, hospital, hotel, restaurant throw light on for a long time.Existing LED lamp radiating effect is bad, greatly reduces its service life.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the LED lamp of a kind of good heat dissipation effect, long service life is provided.
For achieving the above object, the technical solution of the utility model is: a kind of LED lamp, comprise successively from top to bottom lamp holder, fin and lampshade, in described lampshade, be provided with substrate, circumferential uniform LED illuminator on described substrate, formation air compartment stretches out above described fin, in described air compartment, be provided with fan, air compartment bottom is communicated with ventilation duct, described fin is provided with through hole, described ventilation duct is through through hole, ventilation duct arranges in the shape of a spiral, between adjacent two fin, the ventilation duct upper and lower side of part is respectively established a pore, the port of export of described ventilation duct is positioned at substrate top, circumferential uniform louvre on described substrate, described louvre and LED illuminator are crisscross arranged, described lampshade bottom is provided with exhaust vent.
The beneficial effects of the utility model: the wind that fan blows out blows facing to substrate through ventilation duct, the heat on substrate is outside through louvre and exhaust vent runway, reaches ventilation effect; Louvre and LED illuminator are crisscross arranged, the heat that near the LED illuminator better taking away sends; Pore also can blow out micro-wind, accelerates fin heat radiation, further improves radiating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that fin of the present utility model and ventilation duct coordinate schematic diagram;
Fig. 3 is the upward view of substrate of the present utility model.
In figure: lamp holder 1, fin 2, through hole 21, lampshade 3, exhaust vent 31, substrate 4, LED illuminator 41, louvre 42, air compartment 5, fan 6, ventilation duct 7, pore 71.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in FIG. 1 to 3, a kind of LED lamp, comprise successively from top to bottom lamp holder 1, fin 2 and lampshade 3, in described lampshade 3, be provided with substrate 4, circumferential uniform LED illuminator 41 on described substrate 4, described fin 2 tops stretch out and form air compartment 5, in described air compartment 5, be provided with fan 6, air compartment 5 bottoms are communicated with ventilation duct 7, described fin 2 is provided with through hole 21, described ventilation duct 7 is through through hole 21, ventilation duct 7 arranges in the shape of a spiral, between adjacent two fin 2, ventilation duct 7 upper and lower sides of part are respectively established a pore 71, the port of export of described ventilation duct 7 is positioned at substrate 4 tops, circumferential uniform louvre 42 on described substrate 4, described louvre 42 is crisscross arranged with LED illuminator 41, described lampshade 3 bottoms are provided with exhaust vent 31.
LED lamp of the present utility model is opened aft-fan 6 and is also started thereupon, and the wind that fan 6 blows out blows facing to substrate 4 through the ventilation duct 7 of air compartment 5 bottoms, and the heat on substrate 4 is outside through louvre 42 and exhaust vent 31 runways, reaches ventilation effect; Louvre 42 is crisscross arranged with LED illuminator 41, the heat that near the LED illuminator 41 better taking away sends; Pore 71 also can blow out micro-wind, accelerates fin 2 heat radiations, further improves radiating effect.
