Abstract

The utility model discloses a high-power LED casing which comprises at least a piece of heat conduction circle and a heating body. Protruding threads are located at the inside diameter of the heat conduction circle, and concave threads at the inside diameter of the lower part of the heating body corresponds to the heat conduction circle; cooling plates are distributed at the casing of the heating body casing, and the cooling plates are vertical to the casing of the heating body.

Description

High power led housing

Technical field

The utility model relates to lamp outer casing attractive in appearance and heat dissipation technology field, particularly high-powered LED lamp heat dissipation technology field.

Background technology

Led light source is driven by power source special, has constant current, stable, characteristics of high efficiency, and the heat dissipation problem of LED lamp is one of reason that it can not extensive use at present.LED inevitably can produce some heats when converting electric energy to luminous energy, power is big more, and brightness is high more, and the heat of generation is just many more.If heat does not distribute, too high temperature not only can influence the stable of power supply, and can quicken the decay of LED brightness, and then shortens the service life of LED.The key of LED lamp heat radiation is its design of shell, and the problem that high-power LED lamp shell ubiquity outward appearance is coarse, temperature is too high has in the market limited the brightness of light fixture, influences service life.

The utility model content

The utility model is a high power led housing, comprises heat conduction circle and radiator, and it is 0.8 millimeter fin that the radiator shell is distributed with 60 thickness equably; From the radiator cavity inner surface outwards respectively gong go out two circles, its degree of depth is beyond the root of fin, to make cavity wall be worn by spiral shell, makes air-flow form convection current inside and outside fin and radiator, forms heat exchange, helps the heat radiation of LED light fixture.The technical problems to be solved in the utility model is to guarantee exquisite appearance, guarantees that volume, shape, weight meet under the conventional prerequisite that requires, and have optimized radiating effect.

Description of drawings

Fig. 1 is the heat conduction circle schematic diagram of the utility model high power led housing;

Fig. 2 is the radiator schematic diagram of the utility model high power led housing;

Fig. 3 is the utility model high power led housing schematic diagram;

Fig. 4 is the utility model high power led housing vertical section schematic diagram.

The specific embodiment

Shown in figure one, be the utility model high power led housing heat conduction circle schematic diagram.Heat conduction circle 1 is the part that the LED aluminium base is installed, and also is main thermal source.Heat conduction circle 1 internal diameter has outstanding screw thread so that fix with radiator 2.In order to strengthen heat-conducting effect, can between screw thread, coat silicone grease during assembling.As shown in Figure 2, it is 0.8 millimeter fin 21 that the circumference of radiator 2 shells is distributed with 60 thickness equably, to strengthen the contact area of radiator 2 and air; Fin 21 distribution gaps have 2.0 millimeters safe in utilization to guarantee; Radiator 2 bottom internal diameters have the outstanding screw thread of recessed screw thread and heat conduction circle 1 internal diameter to adapt; The high power led housing schematic diagram that Fig. 3 assembles for heat conduction circle 1 and radiator 2; As shown in Figure 4, inside and outside making radiator 2, ventilation function is arranged, from radiator 2 cavity inner surfaces outwards respectively spiral shell go out two circles 22, its degree of depth is 0.5-1.0 millimeter place beyond the root of fin 21, make cavity wall be worn by spiral shell, make air-flow form convection current between fin 21 and inside and outside the radiator 2, form heat exchange.

Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
