Abstract
The utility model relates to a radiating device of an LED (Light-Emitting Diode) lamp, comprising a barrel-shaped body, wherein a lower end opening of the barrel-shaped body is provided with an LED power supply core plate. The radiating device is characterized in that an air-ventilating seam hole is arranged between the periphery of the power supply core plate and the inner wall of the lower opening of the barrel-shaped body; the barrel-shaped body is internally provided with a heat-conducting rod connected with the upper side part of the power supply core plate; the radiating fins are connected onto the heat-conducting rod; and radiating through holes are arranged at the two sides of the barrel-shaped body. The radiating device has the advantages that the structure is simple; the air flow is utilized for air-cooling radiation, so that the radiating mechanism is simplified, a motor does not need to be added, the radiating cost is saved and the service life can also be prolonged.
Description
Technical field
The utility model relates to a kind of LED lamp heat-radiating device, is applied to the heat radiation operation to the LED light fixture.
Background technology
The time that the LED lamp uses is all long, and use can make the caloric value of LED lamp heighten for a long time, the heat radiation of LED lamp at present otherwise adopt the complicated motor-driven heat radiation of mechanism, otherwise be exactly not add any heat abstractor and directly flow through air and cool off.Therefore, to the problems referred to above be the object of the utility model research.
Summary of the invention
The purpose of the utility model is to provide a kind of LED lamp heat-radiating device, has solved the problem that present LED construction for heat radiating device is complicated, radiating efficiency is low effectively.
The utility model is characterised in that: a kind of LED lamp heat-radiating device; Comprise that lower port is equipped with the cylindrical body of LED power supply central layer; It is characterized in that: be provided with circulation of air seam hole between said power supply central layer perimembranous and the cylindrical body under shed inwall; The heat conducting bar that is connected with power supply central layer upper lateral part is installed in the said cylindrical body, is connected with fin on the said heat conducting bar, said cylindrical body two sides are provided with the heat radiation through hole.
The advantage of the utility model: the utility model is simple in structure, utilizes air to flow wind-cooling heat dissipating, has simplified cooling mechanism, and need not add motor, has saved the heat radiation cost, and can also increase the service life.
Description of drawings
Fig. 1 is the utility model example structure cross-sectional schematic.
Fig. 2 is the structure schematic top plan view of the utility model embodiment.
The specific embodiment
With reference to figure 1 and Fig. 2; A kind of LED lamp heat-radiating device; Comprise that lower port is equipped with the cylindrical body 2 of LED power supply central layer 1, be provided with circulation of air seam hole 3 between said power supply central layer 1 perimembranous and the cylindrical body 2 under shed inwalls, the heat conducting bar 4 that is connected with power supply central layer 1 upper lateral part is installed in the said cylindrical body 2; Be connected with fin 5 on the said heat conducting bar 4,2 liang of sides of said cylindrical body are provided with heat radiation through hole 6.
Seam hole on the above-mentioned cylindrical body 2 is a helical form.
Offer on the above-mentioned fin 5 and use so that the air vent 7 that air communication is crossed.
The practical implementation process: air communication is crossed the circulation of air seam hole that is provided with between power supply central layer perimembranous and the cylindrical body under shed inwall and is got in the cylindrical body; Owing to be provided with the heat conducting bar that is connected with the power supply central layer in the cylindrical body; And be connected with fin on the heat conducting bar, will carry out and discharge by the heat that the LED lamp is delivered on the fin through the heat radiation through hole on cylindrical body two sides through the air draught that imports, during; Owing to have air vent on the fin, can make heat-conducting effect better.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
