Abstract

The utility model relates to the technical field of the LED ceiling lamp, concretely to a heat radiator for an LED ceiling lamp, comprising heat radiation fins and heat radiation holes, wherein the heat radiation fins are arranged around the heat radiation holes, one ends of the heat radiation fins are connected with the heat radiation holes, the thickness of the heat radiation fins is gradually increased and clearances are arranged between the adjacent heat radiation fins. The thickness of the heat radiation fins is gradually increased and compared with the surface area of the existing rectangular heat radiation fins, the surface area of the heat radiation fins is relatively larger in same volume, so as to effectively increase the heat radiation efficiency.

Description

A kind of LED pendent lamp is used radiator

Technical field

The utility model relates to LED pendent lamp technical field, is specifically related to a kind of LED pendent lamp and uses radiator.

Background technology

Because LED (light emitting diode) has that volume is little, shock-resistant, life-span length, low power consumption, chemiluminescence and do not have advantage such as mercury pollution, is widely used in the illumination use in the indoor and outdoor places such as enterprises and institutions, hall, meeting room, workshop, shop, Entertainment Plaza.

At present, the input power of LED only has 15～20% to convert light into, and all the other 80～85% forms that convert heat into discharge, if these heats can not be discharged, will cause the temperature of LED crystal grain too high, thereby influence the luminous efficiency of LED lamp, reduce the life-span of LED lamp.

Radiator in the LED light fixture is the topmost radiator structure of LED light fixture, and the structure of radiator comprises louvre and the radiating fin that is arranged at the louvre periphery, and radiating fin is that cross section is the radiating fin of rectangle.

The problem that prior art exists is, the surface area of radiating fin is less, and radiating efficiency is lower.

Therefore, to the problem that exists in the prior art, needing badly provides a kind of LED pendent lamp particularly important with the technology of radiator.

Summary of the invention

The purpose of the utility model is the deficiency to prior art, provides a kind of good heat dissipation effect, LED pendent lamp that surface area is big to use radiator.

The purpose of the utility model realizes through following technical scheme:

Provide a kind of LED pendent lamp to use radiator; Comprise radiating fin and louvre, said louvre periphery is provided with radiating fin, and said radiating fin one end is connected with said louvre; The thickness of said radiating fin becomes greatly gradually, is provided with the gap between the said adjacent radiating fin.

Wherein, an end of said radiating fin minimum thickness is connected with said louvre.

Wherein, said radiating fin is that cross section is trapezoidal radiating fin.

Wherein, the minimum thickness of said radiating fin is 1:1.5～4 with the ratio of maximum ga(u)ge.

Wherein, the minimum thickness of said radiating fin is 1:3 with the ratio of maximum ga(u)ge.

Wherein, said radiating fin is distributed in the periphery of said louvre.

Wherein, said radiating fin equidistance is arranged at the periphery of said louvre.

Wherein, said radiating fin not equidistance be arranged at the periphery of said louvre.

Wherein, said radiating fin and said louvre are one-body molded.

The beneficial effect of the utility model:

A kind of LED pendent lamp is used radiator; Comprise radiating fin and louvre, said louvre periphery is provided with radiating fin, and said radiating fin one end is connected with said louvre; The thickness of said radiating fin becomes greatly gradually, is provided with the gap between the said adjacent radiating fin.

The thickness of radiating fin becomes greatly gradually, makes in the identical volume, and the surface area that the surface area of radiating fin is compared existing rectangle radiating fin is bigger, can effectively improve radiating efficiency.

Description of drawings

Utilize accompanying drawing that the utility model is described further, but the embodiment in the accompanying drawing does not constitute any restriction to the utility model.

Fig. 1 is the structural representation of a kind of LED pendent lamp of the utility model with radiator.

In Fig. 1, comprise:

1---radiating fin, 2---louvre, 3---the gap.

The specific embodiment

Below in conjunction with embodiment the utility model is elaborated.

Embodiment 1

As shown in Figure 1; A kind of LED pendent lamp is used radiator; Comprise radiating fin 1 and louvre 2, said louvre 2 peripheries are provided with radiating fin 1, and said radiating fin 1 one ends are connected with said louvre 2; The thickness of said radiating fin 1 becomes greatly gradually, is provided with gap 3 between the said adjacent radiating fin 1.

The thickness of radiating fin 1 becomes greatly gradually, makes in the identical volume, and the surface area that the surface area of radiating fin 1 is compared existing rectangle radiating fin 1 is bigger, can effectively improve radiating efficiency.

Further, an end of said radiating fin 1 minimum thickness is connected with said louvre 2.Make the periphery of louvre 2 that radiating fin 1 can more be set, farthest increase the surface area of radiating fin 1.

Further, said radiating fin 1 is trapezoidal radiating fin 1 for cross section.

Further, the minimum thickness of said radiating fin 1 is 1:3 with the ratio of maximum ga(u)ge.

Further, said radiating fin 1 is distributed in the periphery of said louvre 2, uniform Design, and radiating effect is best, and said radiating fin 1 equidistance is arranged at the periphery of said louvre 2.Overall appearance, good heat dissipation.

Further, said radiating fin 1 and said louvre 2 are one-body molded.One-body molded, but radiating fin 1 is better with the bonding strength of louvre 2, during collision, can not drop, and influences the use of LED pendent lamp.

Embodiment 2

Embodiment 2 compares with embodiment 1, difference as follows: said radiating fin 1 not equidistance is arranged at the periphery of said louvre 2.

And the ratio of the minimum thickness of radiating fin 1 and maximum ga(u)ge is to select suitable radiating fin 1 between 1:1.5～4 arbitrarily.

Should be noted that at last; Above embodiment is only in order to the technical scheme of explanation the utility model but not to the restriction of the utility model protection domain; Although the utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model, and do not break away from the essence and the scope of the utility model technical scheme.
