Abstract
A light-emitting diode (LED) lighting dissipating heat through convection includes an LED lighting set, a substrate and a cylindrical heat dissipating plate, wherein the LED lighting set is mounted on the bottom surface of the substrate, the substrate is mounted under the heat dissipating plate, the upper surface of the substrate is closely contacted with the bottom surface of the heat dissipating plate, a cavity is disposed in the heat dissipating plate, openings communicated with the cavity are distributed on side faces of the heat dissipating plate, horn-shaped flaring are disposed on the openings on the side faces of the heat dissipating plate , and heat dissipating fins are mounted on the bottom of the cavity in the heat dissipating plate. When the LED lighting set works, heat is transferred to the heat dissipating fins through the bottom surface of the heat dissipating plate, air blown from any directions into the LED lighting dissipating heat through convection in the cavity of the heat dissipating plate because horn-shaped flaring are mounted on the side faces of the heat dissipating plate, thus hot air in the cavity of the heat dissipating plate is blown out, and heat dissipating effect is good. Meanwhile, the LED lighting dissipating heat through convection is simple in structure and low in manufacturing cost.

Background technology
Existing LED lamp is compared with traditional incandescent lamp, fluorescent lamp etc., has incomparable advantage.The LED lamp is also high to the requirement of heat radiation, and the LED light temperature raises, and will cause the life-span of LED lamp to be reduced, and accelerate the light decay of LED lamp.Temperature raises, and the optical wavelength of LED lamp output is changed, and changes color characteristic.
Existing LED lamp has solved the relatively poor problem of its heat radiation, and heat radiation is good, but the radiating mode that existing LED illuminating lamp adopts causes the manufacturing cost of LED illuminating lamp high, is not easy to promote the use of.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of low cost of manufacture, the LED illuminating lamp of the good heat loss through convection that dispels the heat.
in order to solve the problems of the technologies described above, the utility model provides a kind of LED illuminating lamp of heat loss through convection, comprise LED lamp group and substrate, described LED lamp group is arranged on the bottom surface of substrate, it is characterized in that, also comprise heat sink, this heat sink is cylindrical, the upper surface of described substrate is close to the bottom surface of described heat sink and is installed, bottom surface at described heat sink also is equipped with lampshade, described substrate and LED lamp group all are positioned at described lampshade, the inside of described heat sink is provided with cavity, the side of this heat sink is evenly equipped with the opening that is communicated with the cavity of this heat sink, opening part in this heat sink side is equipped with the enlarging of toroidal, the bottom of described heat sink internal cavities is equipped with fin.
The edge of described heat sink bottom surface is provided with one group of through hole, and this through hole is along evenly distributing with the concentric annulus in described heat sink bottom surface.
Good effect of the present utility model is:
LED lamp group is arranged on substrate, substrate is arranged on heat sink, heat sink is cylindrical, the inside of heat sink is provided with cavity, the side of this heat sink is evenly equipped with the opening that is communicated with the cavity of this heat sink, opening part in this heat sink side is equipped with the enlarging of toroidal, in the bottom of heat sink internal cavities, fin is installed.
LED lamp group work heating, heat is delivered on fin by the bottom surface of heat sink, the LED illuminating lamp of this heat loss through convection is crossed in the wind of any direction, the effect of the enlarging of the toroidal of installing due to the heat sink side, convection current occurs in the capital in the cavity of heat sink inside, thereby make the hot-air in the cavity of heat sink be blown, thereby play good radiating effect.
In when, in the cavity of heat sink inside, convection current occuring when, due to the barrier effect of fin to air-flow, can make the part air-flow change direction, changing nyctitropic air-flow one or several through hole by the edge setting of heat sink bottom surface enters in lampshade, hot-air in lampshade blows out by other through hole, thereby the hot-air in lampshade is discharged, further improve radiating effect.
