Abstract

The utility model provides a radiator structure of a light-emitting diode (LED) lamp, which belongs to the field of processing of lighting equipment. The radiator comprises a ring-shaped side wall and is characterized in that a ring-shaped inner groove capable of accommodating an LED light source module is arranged at the opening position on the side wall of the radiator. The ring-shaped side wall of the radiator is in a solid or hollow smooth arc shape. The radiator structure of the LED lamp adopts the groove structure, and accordingly the LED light source module can be directly installed and clamped into the groove and does not need screws and glue to when fixed. A metal base of the LED light source module can be directly contacted with the side wall of the radiator so that heat-dissipation performance is greatly improved, production efficiency can be greatly improved, damage of conducting wires in the productive process is reduced, and production cost is saved.

Description

The heat spreader structures of LED lamp

Technical field

The utility model relates to a kind of lighting apparatus, relates in particular to a kind of heat spreader structures of LED lamp.

Background technology

LED is a kind of low voltage light sources, because its power saving, life-span are long, has been widely used in various low-voltage lighting devices at present; Traditional LED lamp generally is made up of lamp holder, radiator, led light source and lampshade, and wherein the head of radiator is installed lamp holder, the inner led drive circuit of installing; Afterbody is used for installing the led light source module; At the outside lampshade of installing of led light source, traditional radiator generally adopts screw or glue fixing that led light source is installed again, in use because the great power LED caloric value is huge; The long-time back glue easy ageing of using comes off; Then can greatly reduce production efficiency if adopt screw to install, and production process also becomes more complicated, the increase production cost.

Summary of the invention

The technical problem that the utility model will solve is to provide a kind of and can simplifies production process, saves the heat spreader structures of the Novel LED light of production cost.

The utility model is achieved in that a kind of heat spreader structures of LED lamp; Said radiator comprises a circular sidewall; It is characterized in that: on the sidewall of said radiator; Along opening be provided with one can hold the led light source module circular inner groovy, the circular sidewall of said radiator becomes the level and smooth arc of solid or hollow out.

The utlity model has following advantage: the heat spreader structures of the LED lamp of the utility model adopts groove structure; Can the led light source module directly be installed and stick into groove, need not to use screw or glue fixing, and owing to the metab of led light source module can directly contact with the radiator sidewall; Heat dispersion also promotes greatly; And can enhance productivity greatly, reduce the damage of lead in the production process, save production cost.

Description of drawings

Combine embodiment that the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the overall structure sketch map of the radiator of the utility model.

Fig. 2 is the cutaway view of the radiator of the utility model.

The specific embodiment

Come the utility model is carried out detailed explanation below in conjunction with specific embodiment.

See also Fig. 1 to shown in Figure 2; It is the heat spreader structures of the described a kind of LED lamp of the utility model; Said radiator comprises a circular sidewall 11; The sidewall upper edge opening of said radiator be provided with one can hold the led light source module circular inner groovy 12, the level and smooth arc of the solid or hollow out of 11 one-tenth of the circular sidewalls of said radiator.

During use, as shown in Figure 2, led light source module 13 is installed in the circular inner groovy 12 back chuckings on the sidewall of radiator, again lampshade 14 is installed in the outside of led light source module 13, can accomplish the installation of light source module.Adopt the radiator of this structure, can improve production efficiency greatly, reduce the damage of lead in the production process, saved production cost.

In the foregoing description, said radiator can be selected metal material such as aluminium sheet, the copper coin etc. of various high heat radiations, adopts the mould of making in advance to utilize one-shot forming technique, stamps out the shape that needs, and can enhance productivity greatly; And can make the shape of radiator according to the shape of led light source module, and also be not limited to circle, also can do shapes such as squarely or strip, still can reach aforesaid utility model purpose.

Claims

1. the heat spreader structures of a LED lamp; Said radiator comprises a circular sidewall; It is characterized in that: on the sidewall of said radiator; Along opening be provided with one can hold the led light source module circular inner groovy, the circular sidewall of said radiator becomes the level and smooth arc of solid or hollow out.
