Abstract
The utility model provides a chimney type heat-radiating LED (Light-emitting Diode) illumination lamp, comprising a heat-radiating fin and a chip, wherein the chip is mounted on the lower surface of the heat-radiating fin on which a through hole is arranged; the heat-radiating fin is integrally provided with a hollow short heat-radiating pipe; and the short heat-radiating pipe is vertically placed above the heat-radiating fin and a pipe cavity of the short heat-radiating pipe is aligned to the through hole. A heat radiator provided by the utility model not only has a strong heat-radiating effect on air, but also enables air to generate a strong convection effect, so that the heat-radiating effect is good and the temperature of the LED illumination lamp can be effectively reduced; and therefore, lumens depreciation of an LED light source is reduced, the service life of the LED lamp is prolonged and the effect that a light-emitting color is normal is ensured.
Description
Technical field
The utility model belongs to the technical field of LED illuminating lamp, relates in particular to a kind of funnel-shaped heat-dispersion LED lighting lamp.
Background technology
The LED illuminating lamp is the new type light source of a kind of efficient, energy-saving and environmental protection, safety, has progressively replaced conventional light source such as traditional tengsten lamp, fluorescent lamp.But in led chip when work,, 20～30% the power of only having an appointment is converted into luminous energy, and all the other power of 70～80% are converted into heat energy; The degree of heat is quite high; Therefore these heats are effectively distributed rapidly, otherwise can influence LED illuminating lamp operate as normal, the aggravation light decay; Reduction of service life, LED light fixture generation look is floated.
The common structure of existing LED illuminating lamp is to be installed in chip on the fin, in order to make fin cross-ventilation up and down, also on fin, offers through hole.But the cross-ventilation degree of said structure is still not enough, and the area of dissipation of fin is less, thereby radiating effect has much room for improvement.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of funnel-shaped heat-dispersion LED lighting lamp is provided, and its radiator not only can produce the thermolysis than the heat-flash radiation to air, the effect that makes air produce strong convection simultaneously, excellent in heat dissipation effect.
Its purpose can realize by following scheme: this funnel-shaped heat-dispersion LED lighting lamp comprises fin and chip, and chip is installed in the lower surface of fin, offers through hole on the fin; Its main feature is, is formed with hollow heat radiation short tube at said fin, and the heat radiation short tube is erected at the fin top, and the tube chamber of heat radiation short tube is aimed at said through hole.
Said radiator adopts aluminium alloy to make.
Said radiator adopts heat-conducting plastic to make.
The utlity model has following advantage and effect:
1, the utility model becomes the perforation chimney-like owing to set up the heat radiation short tube with fansink designs, and according to stack effect principle and bernoulli equation, because the heat radiation short tube has certain altitude, it just can obtain the motive force of certain gravitational potential; When chip operation, the heat that it produces can be delivered to entire radiator rapidly, and radiator will be to heated with ambient air; Owing to the thermal capacitance of air is very little, its temperature of being heated a little will rise rapidly, volumetric expansion, and therefore hot-air rises, and negative pressure appears in heat radiation short tube inside, and the air of bottom is absorbed and replenishes into, and the heat that chip produces has become the power that the promotion air flows.For above-mentioned reasons, the air in LED heat radiation short tube will make progress fast and flow, and produces strong convection effects, takes away the heat that chip produces effectively.
2, because heat radiation short tube and radiator are integrally formed, also significantly increased the contact area (cooling surface area) of thermal component and air, made the convection current of thermal component and heat loss through radiation ability that bigger lifting all arranged.
Owing to above-mentioned two aspect reasons, the structure good heat dissipation effect of the utility model can reduce the temperature of LED illuminating lamp effectively, and then reaches and reduce the led light source light decay, prolong LED lamp service life, guarantee the normal effect of glow color.
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
The specific embodiment
Funnel-shaped heat-dispersion LED lighting lamp shown in Figure 1 comprises power supply module 5, aluminum alloy heat sink 1 and chip 2, and chip 2 is installed in the lower surface of fin 1, and chip 2 belows are provided with lens 4, offer through hole 11 on the fin 1; Be formed with hollow heat radiation short tube 3 at fin, heat radiation short tube 3 is rounded, and heat radiation short tube 3 is erected at fin 1 top, and the tube chamber 31 of heat radiation short tube 3 is aimed at said through hole 11.
Above-mentioned fin 1 also can adopt the nonmetallic materials of high heat dispersion to make.
