Abstract

The invention is a light-emitting diode (LED) radiator, comprising LED, first radiating fin, and second radiating fin, where a hot tube is connected between the two radiating fins, and the LED contacts with the first radiating fin or hot tube and can be cooled by the two radiating fins, and because of adopting two radiating fins, it can raise radiating efficiency, thus able to match with a LED with higher luminous intensity.

Description

The heat abstractor of light-emitting diode

Technical field

The present invention relates to a kind of heat abstractor of light-emitting diode.

Background technology

In the prior art, the heat abstractor of light-emitting diode generally includes one group of radiating fin, wherein, radiating fin contacts with light-emitting component, the heat transferred of the luminous generation of light-emitting component is to radiating fin, thereby the light-emitting component to heating dispels the heat, but this method of single group radiating fin heat transfer that adopts makes that the radiating effect of this heat abstractor is relatively poor, so this heat abstractor can only be applied on the lower single wick luminaire of power usually, big or the duplex wick luminaire for power, this heat abstractor is promptly crossed low owing to radiating efficiency and can't be used.

Summary of the invention

The object of the invention provides a kind of heat abstractor of light-emitting diode, and its radiating efficiency is higher.

Technical scheme of the present invention is: a kind of heat abstractor of light-emitting diode, it comprises light-emitting diode, first radiating fin, second radiating fin, be connected with heat pipe between described first radiating fin and described second radiating fin, described light-emitting diode contacts with first radiating fin or heat pipe.

The adjacent side of described second radiating fin is provided with cooling fan.

Be connected with installing rack on described second radiating fin, described cooling fan is arranged on the installing rack.

Described heat pipe is positioned at the downside of first radiating fin, and described second radiating fin is positioned at the downside of heat pipe.

The present invention compared with prior art, have following advantage: light-emitting diode can be by first radiating fin and the heat radiation of second radiating fin, transmit heat by heat pipe between two fins, owing to adopted two groups of radiating fins, so can improve the radiating efficiency of this heat abstractor, and can make second radiating fin be arranged at position away from first radiating fin, be convenient to the designer and carry out, thereby make the application that can match with the higher light-emitting diode of luminous intensity of this heat abstractor with the design and the layout of light-emitting diode as the luminaire of light source.

Embodiment

Shown in accompanying drawing 1 one accompanying drawings 3, a kind of heat abstractor of light-emitting diode, it comprises light-emitting diode 10, first radiating fin 2, second radiating fin 4, be connected with heat pipe 3 between described first radiating fin 2 and described second radiating fin 4, described light-emitting diode 10 contacts with first radiating fin 2 or heat pipe 3.

The adjacent side of described second radiating fin 4 is provided with cooling fan 6, is connected with installing rack 5 on described second radiating fin 4, and described cooling fan 6 is arranged on the installing rack 5.In the embodiment shown in Figure 2, described heat pipe 3 is positioned at the downside of first radiating fin 2, and described second radiating fin 4 is positioned at the downside of heat pipe 3, and installing rack 5 is positioned at the downside of second radiating fin 4; In the embodiment shown in Figure 3, installing rack 5 and 6 sides that are arranged at second radiating fin 4 of cooling fan.

The outside of described light-emitting diode 10 is covered with lampshade 1, has hook 7 on the described lampshade 1, has gib head 8 on the described hook 7, has stopper slot 9 on described first radiating fin 4, and described gib head 8 is inserted in the stopper slot 9.

In Application Example of the present invention, make lampshade 1 be connected by linking up with 7 with the cooperation of stopper slot 9 with first radiating fin 2, first radiating fin 2 promptly contacts with light-emitting diode 10, the heat delivered that produces during the luminous work of light-emitting diode 10 is to first radiating fin 2, being connected with heat pipe 3, the first radiating fins 2 between described first radiating fin 2 and described second radiating fin 4 outwards disperses heat simultaneously and by heat pipe 3 the part heat is delivered on second radiating fin 4.Have a plurality of capillaries and medium in the inner chamber of heat pipe 3, in the end that heat pipe 3 is connected with first radiating fin 2, liquid medium in the capillary is heated and vaporizes and need heat absorption, can reduce the temperature of first radiating fin 2, medium vaporization back is in heat pipe 3 and 4 joint condensations of second radiating fin and heat radiation, make heat transferred on the radiating fin 2 of winning to second radiating fin 4, carry out air cooling by 6 pairs second radiating fins of cooling fan 4 again, make that the light-emitting diode 10 of heating is dispelled the heat in time.
