Abstract

The utility model discloses a lamp radiating device which comprises a base plate (1), radiating fins (2), a sleeve (3) and screws (4). The base plate (1) is a circular metal plate provided with a circular through hole in the middle. Mounting holes are evenly distributed on the periphery of the through hole. Each radiating fin (2) is of a metal thin-plate structure. The radiating fins (2) are evenly welded to the upper plane of the base plate (1) along the circumferential direction of the base plate (1). The sleeve is provided with a hollow structure. One end of the sleeve (3) is fixedly connected with the base plate through the screws (4), and the other end thereof is provided with outer threads. The lamp radiating device has the advantages that radiating area is increased while flexible structure is achieved, mold restriction is avoided, and different radiating efficiency can be achieved by changing size of corresponding parts; the hollow sleeve can be used for placing an LED drive power supply or protect a transmission line penetrating the sleeve; the lamp radiating device is simple in structure and suitable for customized production.

Description

Lamp heat-radiating device

Technical field

The utility model relates to a kind of lamp heat-radiating device, specifically a kind of lamp heat-radiating device for the LED light fixture is dispelled the heat.

Background technology

The LED light fixture is in the process of electrified light emitting, is the process that is luminous energy and heat energy by electric energy conversion.High temperature can have influence on the light extraction efficiency of LED light fixture, stability and the service life of work, so need to have good cooling system in the LED light fixture.

Cooling system commonly used adopts radiator heat-dissipation more at present, the Main Function of radiator is that the heat will produced in LED chip work is constantly derived and is dispersed in environment, the temperature of chip is remained in desired scope, thereby guarantee that the LED lamp can work.

Radiator commonly used can be divided into die casting radiator and crowded type radiator according to its production technology, and the die casting radiator generally adopts allumen, and its shortcoming is that thermal diffusivity is less better, and need to be by costly die casting; Squeeze the type radiator similar with the die casting radiator, its radiating fin thin and thick is compared die casting and is more easily controlled, cooling surface area increases, heat dispersion is better than the die casting radiator, but product two end sections are consistent, structure is single, not as the die casting form, can make flexibly corresponding structural form, with other parts of light fixture, is assembled with difficulty.

Summary of the invention

For the problems referred to above, the utility model provides a kind of lamp heat-radiating device, can realize larger area of dissipation and version more flexibly, and is convenient to be connected other parts of light fixture.

For achieving the above object, the utility model comprises base plate, radiating fin, sleeve and screw, and base plate is the round structure metallic plate, and centre is provided with circular hole, and the circular hole periphery has screwed hole; Radiating fin is metal material sheet-type structure, along base plate circumferencial direction uniform welding plane thereon; Sleeve is provided with hollow structure, and an end is fixed in the middle of base plate by screw, and the other end is provided with external screw thread.

Preferably, base plate and radiating fin all adopt aluminium material matter.

Compared with prior art, the utility model has guaranteed that radiator has version more flexibly when improving area of dissipation, not fettered by mould, and the size that changes corresponding component can obtain different heat dissipations; The sleeve of hollow can be placed the LED driving power or protect the transmission line of electricity therefrom passed; Simple in structure, be applicable to customized production.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is perspective view of the present utility model;

Fig. 3 is the back side of the present utility model perspective view.

In figure: 1, base plate, 2, radiating fin, 3, sleeve, 4, screw.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, Figure 2, shown in Fig. 3, this lamp heat-radiating device comprises base plate 1, radiating fin 2, sleeve 3 and screw 4.

Base plate 1 is the round structure metallic plate, and centre is provided with manhole, is evenly equipped with installing hole around hole.

Radiating fin 2 is metal material sheet-type structures, the upper plane along base plate 1 circumferencial direction uniform welding at base plate 1.

Sleeve 3 is provided with hollow structure, and an end is fixedly connected with base plate by screw 4, and the other end is provided with external screw thread.

Base plate 1 and radiating fin 2 materials can adopt copper material or aluminium material, because latter's cost is lower and lightweight, therefore preferably adopt aluminium material matter.

The sleeve 3 of hollow, its inside can not be exposed to outside radiator transmission line of electricity or driving power through the driving power of transmission line of electricity or light fixture, plays a protective role; Height by different base plates 1 area or radiating fin 2 and sleeve 3, can obtain different heat dissipations.

This lamp heat-radiating device has guaranteed that radiator has version more flexibly when improving area of dissipation, not fettered by mould, according to the different size of corresponding component, can obtain different radiating effects; The sleeve of hollow can be placed the LED driving power or protect the transmission line of electricity therefrom passed; Simple in structure, be applicable to customized production.
