Abstract

The invention discloses an LED (Light-Emitting Diode) lamp radiating fin comprising a base plate and a plurality of radiator fins arranged on the base plate, wherein the base plate is of a semicircular arc structure; bent bases are symmetrically arranged on the bottom of the base plate; the radiator fins comprise a plurality of first radiator fins, second radiator fins, third radiator fins and fourth radiator fins; the first radiator fins, the second radiator fins, the third radiator fins and the fourth radiator fins are sequentially arranged in a staggered manner; the sizes of the first radiator fins are as same as those of the third radiator fins and are smaller than those of the second radiator fins; and the sizes of the second radiator fins are smaller than those of the fourth radiator fins. According to the LED lamp radiating fin provided by the invention, the radiator fins are well arranged in a staggered manner, and the side walls of the radiator fins form a corrugated structure, so that the radiating area is increased; the structure is simple and the assembly is convenient; the heat produced by an LED lamp is radiated into air via the radiator fins so that the radiating performance is good; and meanwhile, a lamp holder of the LED lamp can be supported by the bases so that the radiating fin is integrated with the lamp holder.

Description

LED lamp fin

Technical field

The present invention relates to a kind of LED lamp fin, belong to lighting technical field.

Background technology

At present, common LED lamp is by carrying out heat exchange between the radiating seat of aluminum and the extraneous air mostly, and the radiating effect of common radiating seat is not good, and its complicated integral structure, heaviness and cost height; Another kind of radiator structure is in the periphery of radiating seat a plurality of fin to be set, and with the quickening radiating rate, but because the area of fin is less, does not still reach radiating effect efficiently.

Summary of the invention

Purpose: in order to overcome the deficiencies in the prior art, the invention provides a kind of LED lamp fin.

Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of LED lamp fin, comprise substrate and the some radiating fins that are arranged on the described substrate, it is characterized in that: described substrate becomes the semicircle arc structure, the bottom of described substrate is symmetrically arranged with the bending base, described radiating fin comprises several first radiating fins, second radiating fin, the 3rd radiating fin and the hot fin that scatters, the hot fin arrangement straggly successively that scatters of described first radiating fin, second radiating fin, the 3rd radiating fin and; Wherein first radiating fin is identical with the geomery of the 3rd radiating fin, and less than the size of second radiating fin; The size of second radiating fin is less than size that scatters hot fin.

Described LED lamp fin is characterized in that: the described substrate left and right sides is symmetrically arranged with " L " type kink.

Described LED lamp fin is characterized in that: described first radiating fin, second radiating fin, the 3rd radiating fin and sidewall that scatters hot fin become wave structure.

Described LED lamp fin is characterized in that: described LED lamp fin is the aluminium section bar of surface through anodized.

Beneficial effect: LED lamp fin provided by the invention, radiating fin is arranged in picturesque disorder, sidewall becomes wave structure, increase area of dissipation, simple in structure, easy for installation, the heat that the LED lamp produces is dispersed in the air by radiating fin, have excellent heat dispersion performance, base plays the effect of lamp socket simultaneously, realizes the integrated of fin and lamp socket.

Description of drawings

Fig. 1 is structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done further explanation.

As shown in Figure 1, a kind of LED lamp fin, comprise substrate 1 and the some radiating fins that are arranged on the described substrate, it is characterized in that: 1 one-tenth semicircle arc structure of described substrate, the bottom of described substrate is symmetrically arranged with bending base 2, described radiating fin comprises several first radiating fins 3, second radiating fin 4, the 3rd the radiating fin 5 and hot fin 6 that scatters, hot fin 6 arrangement straggly successively that scatters of described first radiating fin 3, second radiating fin 4, the 3rd radiating fin 5 and; Wherein first radiating fin 3 is identical with the geomery of the 3rd radiating fin 5, and less than the size of second radiating fin 4; The size of second radiating fin 4 is less than size that scatters hot fin 6.Described first radiating fin 3, second radiating fin 4, the 3rd radiating fin 5 and sidewall that scatters hot fin 6 become wave structure.There is the radiating fin of corrugated sidewall to increase area of dissipation, significantly improves the radiating effect of fin.

Described LED lamp fin is characterized in that: described substrate 1 left and right sides is symmetrically arranged with " L " type kink 7.

As preferred version, described LED lamp fin is characterized in that: described LED lamp fin is the aluminium section bar of surface through anodized.

LED lamp fin provided by the invention, radiating fin is arranged in picturesque disorder, sidewall becomes wave structure, increase area of dissipation, simple in structure, easy for installation, the heat that the LED lamp produces is dispersed in the air by radiating fin, have excellent heat dispersion performance, base plays the effect of lamp socket simultaneously, realizes the integrated of fin and lamp socket.

The above only is preferred embodiment of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
