Abstract

The utility model discloses a radiator for LED lamps. A lamp driving power supply is arranged inside the radiator, and an LED light source board is mounted on the lower end surface; fins raised outwards are uniformly distributed on the outer surface of the radiator in a helicoidal manner; one end of each fin, which is close to the LED light source board, is bent towards the radial direction of the radiator; the fins take the shape of arcs which rotate in the same directions; groove-shaped stripes are formed on two sides of the fins; the lower end surface of the radiator takes the shape of a disk; radiating grooves are formed in the end surface in the radial direction in a radial manner and positioned between the fins; and the radiating grooves are square grooves. The fins raised outwards are uniformly distributed on the outer surface of the radiator in a helicoidal manner, so that the appearance is attractive, air circulation can be promoted, and the radiating property can be improved; each fin is arc-shaped, and the groove-shaped stripes are additionally arranged on two sides of the fins, so that the radiating area is enlarged to the utmost extent; the square grooves are formed between the fins so as to help heat inside an LED lamp to be directly transmitted into air and effectively improve the radiating property of the LED lamp, so that an LED light source can be enabled to work normally, and the service life of the LED lamp can be prolonged.

Description

A kind of LED lamp radiator
Technical field
The utility model relates to a kind of radiator, relates in particular to a kind of LED lamp radiator.
Background technology
The caloric value of LED light source is usually all larger, and light fixture need to have good heat dispersion to guarantee the normal use of light fixture.The most of radiating effects of common LED lamp radiator are not good, affected the normal use of LED light source, directly cause the LED light fixture to damage or shorten the service life of light fixture.
The utility model content
The purpose of this utility model is to provide a kind of LED lamp radiator with great heat radiation effect, has effectively improved the heat dispersion of LED light fixture, thereby makes LED light source normal operation, extends LED light fixture service life.
The utility model adopts following technical scheme to realize:
A kind of LED lamp radiator, this radiator inside is provided with the light fixture driving power, and lower surface is equipped with the LED light source plate, it is characterized in that, and the outer surface of described radiator is evenly distributed with outwards outstanding fin in the shape of a spiral.
Further, an end of the close LED light source plate of described fin radially bends to radiator, and every fin forms homodromal arc shaped.
Further, the both sides of described fin have groove shape striped.
Further, described radiator lower surface is discoid, lower surface radially be the radial radiating groove that has, described radiating groove is between fin.
Further, described radiating groove is square groove.
The useful technique effect that the utility model possesses is: the outer surface of radiator is evenly distributed with outwards outstanding fin in the shape of a spiral, and handsome in appearance and promotion circulation of air improves heat dispersion; Each fin is that circular arc type and fin both sides have increased the groove striped, has increased to greatest extent area of dissipation; Have square groove in the middle of fin, contribute to LED lamp interior heat to be directly delivered in the middle of air.

Fig. 8 is the partial enlarged drawing of fin grooves on two sides shape striped.
The specific embodiment
By the following description to embodiment; to more contribute to public understanding the utility model; but specific embodiment that can't the applicant is given is considered as the restriction to technical solutions of the utility model, any definition to parts or technical characterictic changed and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
Typical case of the present utility model uses embodiment---LED bulb lamp as shown in Figure 1 to Figure 8 shows the, the light fixture driving power can be placed in LED lamp radiator inside, other structural member installation code lamp holder 5 can be passed through in upper end, and LED light source plate and PC lampshade 6 are directly installed in lower surface.Radiator uses the modified plastics injection mo(u)lding, can certainly be aluminium alloy, pottery or other material.The outer surface of radiator 1 is evenly distributed with outwards outstanding fin 2, fin 2 is near an end the radially bending to radiator 1 of LED light source plate, every fin forms homodromal arc shaped, many fins form the structure of many rotation arc shapeds, not only handsome in appearance, promote that circulation of air improves heat dispersion simultaneously.The both sides of fin 2 have groove shape striped 3, have increased to greatest extent area of dissipation.The lower surface of radiator 1 is discoid, lower surface radially be the radial radiating groove 4 that has, radiating groove 4 is between fin, radiating groove 4 is square groove, can certainly be other shapes, as long as contribute to the bulb lamp internal heat to be directly delivered in air.In sum, the groove shape striped of the fin on radiator and both sides thereof, coordinate radiating groove not only to promote circulation of air, and increased to greatest extent area of dissipation, impel the heat of bulb lamp inside to be directly delivered to air, reached good radiating effect.
Certainly; the utility model can also have other various embodiments; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
