Abstract

The utility model discloses an LED light fitting radiator which comprises a centre post body and radiating pieces, wherein, the radiating pieces are fixedly arranged on the outer wall of the centre post body; the radiating pieces are arranged in radial shape; at least one radiating post body is arranged between the centre post body and the outer contour line of the radial-shaped radiating pieces; and the radiating post body is in parallel with the axes of the centre post body. Meanwhile, the centre post body is provided with the radiating pieces the surface of which forms a wave shape, the radiating area is increased, and so the radiating effect is increased.

Description

A kind of LED lamp radiator

[Ji Intraoperative field]

The utility model relates to a kind of LED light fixture, relates in particular to a kind of radiator of the LED of being used for light fixture heat radiation.

[Bei Jing Ji Intraoperative]

Fast development along with global economy, the energy consume significant, how to reduce energy consumption and become global problem, it also is the problem that each country can't avoid, therefore, at lighting field, the LED light fixture also just arises at the historic moment, adopt the LED light fixture, can reduce energy consumption, and brightness is unaffected, but adopts the LED light fixture neither just not have defective, because in the process that adopts the LED illumination, the caloric value of LED is big, if this heat can not distribute, must influence the brightness of LED, mostly dispel the heat at present by aluminum hollow cylinder and the mode that on hollow cylinder, is provided with radial fin, the surface of fin is the plane, adopts this mode the heat that the LED light fixture produces can be distributed a part and goes out, but owing in the middle of light fixture and radiator, be separated with a plate, therefore, radiating effect is had a greatly reduced quality.

[utility model content]

In order to solve above-mentioned technological deficiency, the utility model purpose is to provide a kind of increase heat-delivery surface, and with the LED lamp radiator that LED directly links to each other with thermal column, radiating effect is obviously increased.

For achieving the above object, technical scheme that the utility model adopts is: a kind of LED lamp radiator, comprise center column, be fixedly arranged on the fin on the center column outer wall, described fin is radial setting, at least be provided with a heat radiation cylinder between the outer contour of center column and radial fin, described heat radiation cylinder is parallel with the center column axis.

Described heat radiation cylinder is solid or hollow, and cylindricality is circular or irregular shape.

Directly link to each other between described heat radiation cylinder and the center column or be connected by the number of metal sheet.

Described hollow heat radiation cylinder endoporus is screwed hole or light face or ripple face; Described fin surface undulate.

Described hollow heat radiation cylinder end face spins or is crimped with the LED thermal component.

Described LED thermal component welding or bonding or be crimped on solid heat radiation cylinder end face perhaps is encapsulated in the LED thermal component heat radiation cylinder end face.

The beneficial effects of the utility model: on radiator, be provided with one or more thermal column, the corresponding LEDs of each thermal column, directly link to each other between heat radiation cylinder and the center column or be connected by the number of metal sheet, on cylinder, be provided with simultaneously the fin of surperficial undulate, increase radiating surface, thereby increased radiating effect.

[specific embodiment]

For the purpose of this utility model, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

See also Fig. 1, shown in Figure 3, the utility model has disclosed a kind of LED lamp radiator, comprise center column 1, be fixedly arranged on the fin 2 on center column 1 outer wall, described fin 2 is radial setting, on the outer wall of center column 1, be provided with a heat radiation cylinder 3 at least, the heat radiation cylinder 3 be provided with number as required the mounted LEDs number determine, what the LED light fixture of relatively using always adopted at present is the 1-12 LEDs, therefore the heat radiation cylinder 3 of respective number need be set on radiator accordingly, in each heat radiation cylinder 3, be provided with screwed hole 4, be convenient to LED thermal component 5 is fixedly installed on the radiator, also screwed hole 4 can be made light face or ripple face, 5 of LED thermal components can be spun or be crimped on the end face of heat radiation cylinder 3 of radiator.Heat radiation cylinder 3 and screwed hole 4 or light face are all parallel with the axis of center column 1.The shape of heat radiation cylinder 3 can be circular or other are irregularly shaped, can make hollow or solid, if described heat radiation cylinder 3 is made solid, then LED thermal component 5 can be fixed on heat radiation cylinder 3 end faces by the welding or the mode of bonding or crimping, perhaps directly led chip be encapsulated in heat radiation cylinder 3 end faces.

Structure shown in Figure 2 represents to install the situation of 7 LEDs, on the outer wall of center column 1, be provided with 6 heat radiation cylinders 3, be provided with screwed hole 4 in the every heat radiation cylinder 3, also screwed hole 4 can be made light face or ripple face, in center column 1, also be provided with a heat radiation cylinder 3, described heat radiation cylinder 3 links together by number of metal sheet 6 and center column 1, is provided with screwed hole 4 in the heat radiation cylinder 3; Be convenient to connect the LED thermal component.Simultaneously, in order to improve the heat radiation quality, thereby therefore waviness is done on the surface of fin 2 has increased surface area, has improved radiating efficiency accordingly, and the heat that LED is produced is in the course of the work distributed.
