Abstract

An efficiently-dissipating heat-dissipation module of light-emitting diode (LED) lamps comprises a metal base seat, a plurality of cone-shaped heat-dissipation columns are arranged on an outer side of the metal base seat and at least one heat-dissipation fin is arranged on an outer surface of the cone-shaped heat-dissipation columns. The efficiently-dissipating heat-dissipation module of the LED lamps has the advantages of being good in heat-dissipation and prolonging service life. The efficiently-dissipating heat-dissipation module of the LED lamps can apply to outdoor LED lamps in a large number, such as LED street lamps, LED tunnel lamps and LED wall washer lamps.

Description

The LED lamp radiating module of high efficiency and heat radiation

Technical field

The utility model relates to a kind of LED lamp radiating module of high efficiency and heat radiation.

Background technology

The fin of general LED light fixture is all the fin of aluminium extruded formula, and this fin design has directional problems, promptly different service orientations, because of fin forward reaches the reverse wind speed that it flows through fin can be different, therefore can cause the different radiating ability; Also have some to be the design of die casting formula cylinder; Though the cylinder design does not have the problem of direction in use; But its shortcoming is that the surface area of in certain volume size, creating is less relatively; The thermal source that can't effectively LED be produced carries out heat exchange through its surface with air; And because the thermal source of tens watts of supreme hectowatts of integral type design all concentrates on the single aluminium fin formula shell, the thermal source inequality that heat conduction is whole, and then make internal work (Tj) temperature of each LEDs all inequality; Especially the LED that is positioned at the middle part is especially because receive encirclement and long-term work that LED on every side produces thermal source under maximum temperature, and then makes the LED in centre do sth. in advance dead lamp failure.

The utility model content

In order to overcome the problems referred to above, the utility model provides a kind of thermal diffusivity better to society, can improve the LED lamp radiating module of the high efficiency and heat radiation in LED lamp service life.

The technical scheme of the utility model is the LED lamp radiating module of a kind of high efficiency and heat radiation of design, comprises metal base, is provided with several cone thermal columns in the outside of said metal base.

As improvement, on said cone thermal column outer surface, be provided with a slice radiating fin at least to the utility model.

As the improvement to the utility model, said radiating fin is the 3-5 sheet.

As the improvement to the utility model, said radiating fin is that the axis with the cone thermal column is that the center is equally distributed.

As the improvement to the utility model, said radiating module is processed by aluminum alloy materials.

The utility model has adopted new design conception, at first replaces the heat dissipation design of fin type or column type with cone, has directionality heat dissipation different problems to improve former fin type; And on cone, increased by three to five outstanding fin; So can effectively increase the surface area that it contacts with air, and, be distributed in different directions because of the fin that is increased is positioned at the surface of cone; So design approximately can be at (length/width/height identical situation under) on the identical radiator structure size; Newly-increased 7 ~ 10% the surface area of createing to be increasing whole heat-sinking capability, so that LED integral heat sink ability increases, and reduces the operating temperature of LED; Problems such as heat-sinking capability that the different wind directions of horizontal plane are caused is uncertain be can accomplish simultaneously not receive to come from again, the effect that the LED life-span prolongs and the cost performance of increase LED light fixture reached.

The utility model can be widely used on the indoor and outdoor LED light fixture, on all kinds of LED light fixtures of LED street lamp, LED Tunnel Lamp, LED wall lamp or the like.

Fig. 1 is the perspective view of a kind of embodiment of the utility model.

Fig. 2 is that the A of Fig. 1 is to the planar structure sketch map.

Fig. 3 is the planar structure sketch map at B place among Fig. 2.

The specific embodiment

See also Fig. 1 to Fig. 3, what Fig. 1 to Fig. 3 disclosed is a kind of LED lamp radiating module of high efficiency and heat radiation, comprises metal base 1, is provided with several cone thermal columns 2 in the outside of said metal base 1.In order further to improve the heat dispersion of the utility model, on the outer surface of said cone thermal column 2, be provided with several pieces radiating fins 3.In the present embodiment, said radiating fin 3 is 3, and obviously, said as required radiating fin 3 can be designed as the structure of 1-5 sheet.

In the utility model, said radiating fin 3 is that the axis with cone thermal column 2 is that the center is equally distributed.And said radiating module is processed by aluminum alloy materials, and obviously, the utility model also can adopt other to have good thermal conductive material and make.
