Abstract

The utility model relates to a metal heat radiation sheet of LED luminaire, which includes a heat-radiation base, wherein a plurality of heat-radiation fins are formed on the periphery of the heat radiation base, the heat radiation base and the heat-radiation fins form a heat radiation luminaire mounting groove together, and the heat-radiation base is connected with the connecting parts of the heat-radiation fins through arc fins; a silicon-contained heat-radiation layer is arranged on the heat-radiation base. Due to the adoption of the LED mounting groove formed by the heat-radiation base and the heat-radiation fins, and the silicon-contained heat-radiation layer arranged on the heat-radiation base, the metal heat-radiation sheet enable plenty of heat energy released from an LED light to be mainly accumulated in the mounting groove, and the heat energy can be easily absorbed and guided through the arc heat-radiation fins; and meanwhile the silicon-contained heat-radiation layer can enhance the transmission of harmful heat energy, so that the service life of the LED luminaire is prolonged.

Description

A kind of LED light fixture metal fin

Technical field

The utility model relates to a kind of metal fin, especially relates to a kind of LED light fixture metal fin.

Background technology

Along with the progress of science and technology and the development of society, light emitting diode (LED) light fixture has practicality and the value of saving the energy widely because of it, thereby is also referred to as the century new light sources.But, LED in actual use, the specific of excessive and difficult heat radiation of dispelling the heat is called as a great technical barrier of LED field of light fittings always.

Thereby the LED light fixture all will be used with metal fin usually.As described in Figure 1, traditional LED light fixture fin mainly is made of a cylindricality metal fin, and its center is the cooling base 2 that connects the LED light fixture, with cooling base 2 be the center outwards with a plurality of radiating fins 1 of radiation, also be provided with installing hole 3 in the outer rim of this fin.But the metal fin heat-dissipating space of this structure and limited with the effective attaching space of LED causes radiating effect unsatisfactory, has influence on the service life of LED light fixture.

The utility model content

The utility model has designed a kind of LED light fixture metal fin, and it has solved the problem of traditional LED light fixture fin poor effect.

In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:

A kind of LED light fixture metal fin, comprise a cooling base, form a plurality of radiating fins at described cooling base periphery, the common heat radiation light fixture mounting groove that forms of described cooling base and a plurality of radiating fin, described cooling base is connected by the arc fin with a plurality of radiating fins junction; On described cooling base, be provided with siliceous heat dissipating layer.

Further, described a plurality of radiating fin outer rims place also is provided with the installing hole that uses for the assembling light fixture.

Further, the spacing between described adjacent two radiating fins is no more than 2mm.

This LED light fixture fin is compared with traditional LED light fixture fin, have following beneficial effect: the utility model is owing to the LED mounting groove that forms by cooling base and radiating fin, and on cooling base, be provided with siliceous heat dissipating layer, a large amount of heats that will make the LED lamp discharge mainly concentrate in the mounting groove, and be easier to be absorbed and conduction by the radiating fin of arc, siliceous heat dissipating layer can quicken the conduction of harmful heat simultaneously, has prolonged the service life of LED light fixture.

The specific embodiment

Below in conjunction with Fig. 2, the utility model is described further:

A kind of LED light fixture metal fin, comprise a cooling base 2, form a plurality of radiating fins 1 at described cooling base 2 peripheries, described cooling base 2 and a plurality of radiating fin 1 common heat radiation light fixture mounting groove 4 that forms, described cooling base 2 is connected by arc fin 11 with a plurality of radiating fins 1 junction; On described cooling base 2, be provided with siliceous heat dissipating layer 5.

So structure can allow a plurality of LED lamps be arranged in mounting groove 4, a large amount of heats that a plurality of LED lamps discharge mainly concentrate in the mounting groove 4, and be easier to be absorbed and conduction by the radiating fin 1 of arc, siliceous heat dissipating layer can quicken the conduction of harmful heat simultaneously, has prolonged the service life of LED light fixture.

Described a plurality of radiating fin 1 outer rim place also is provided with the installing hole 3 that uses for the assembling light fixture.This installing hole 3 can make things convenient for the LED light fixture to be connected with this metal fin and install.

In addition, the spacing between described adjacent two radiating fins 1 is no more than 2mm.Less spacing helps to be provided with radiating fin 1 as much as possible, improves the effect of heat radiation.

As shown in Figure 3, on described cooling base 2, be provided with siliceous heat dissipating layer 5.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
