Radiating LED lamp

Technical field

The utility model is related to technical field of LED illumination more particularly to a kind of radiating LED lamps.

Background technology

LED light is the lamps and lanterns being made as light-emitting component using light emitting diode.Since LED light has energy saving, long-lived, ring It protects, without superior functions such as stroboscopics, trend is had become as lighting source using LED light, LED light is also used in various fields It closes.But since LED can generate heat at work, poor heat radiation then can substantially shorten the service life of LED light, it is therefore necessary to according to Demand is installed and used, LED light is further designed, radiating requirements are met.

Utility model content

The technical problems to be solved in the utility model is：In order to overcome the deficiency of the prior art, the utility model to provide one Kind simple structure and reasonable design can effectively guide generation heat in work to dissipate outward, poor heat radiation is avoided to shorten the working life Radiating LED lamp.

Technical solution adopted by the utility model to solve its technical problems is：A kind of radiating LED lamp, including radiation shell Body, the radiating shell interior sealing are connected with lamp cap, and lamp cap outer end connection has PCB lamp board, the radiating shell Bottom surface is connected with protecgulum, and then there is in the radiating shell between PCB lamp board reflector, the reflector inner surface to have same The heart and the gradual increased reflective raised line of radius；The radiating shell peripheral radius gradually increases from top to bottom, the radiation shell External circumferential surface uniform intervals are fixed with cooling fin, and the cooling fin is inverted Y types along radiating shell peripheral surface section, described to dissipate Backing along radiating shell soffit plane direction section be Y types and centered on along radiating shell soffit plane center it is radial to Outward opening, the cooling fin are opened along the Y types opening portion of radiating shell peripheral surface and the Y types along radiating shell soffit plane direction Oral area is combined and is protruded along the opening portion of the Y types in radiating shell soffit plane direction and opened with the Y types along radiating shell peripheral surface Oral area.

When work, lamp cap generation heat can outward be exchanged heat by radiating shell to be distributed.The heat dissipation of radiating shell surface design Piece can then be effectively increased the surface area of radiating shell, while the design of Y types, top lamp cap heat can be directed at protecgulum, lamp Head central part heat is guided to cooling fin peripheral end face, has carried out good drainage to hot-air around heat and radiating shell, has had Conducive to raising radiating efficiency.

Further, in order to preferably increase radiating shell surface area, radiating efficiency is improved, between adjacent two panels cooling fin Radiating shell on also have protrusion radiating ribs.Radiating ribs will not dissipate the opening portion hot-air of Y types in the bottom of cooling fin Hair causes to stream.

Further, cooling fin, radiating ribs and radiating shell are structure as a whole.The cooling fin of integral structure, radiating ribs It is completely embedded with radiating shell, can be convenient for generating the conduction of heat inside when work, improve radiating efficiency.

Correspondingly, being provided with slot on radiating shell, the cooling fin corresponds to slot plugged and fixed on radiating shell.Grafting Formula is fixed on the cooling fin on radiating shell, and big smallest number is no longer fixed, can be selected according to the power and radiating requirements of practical LED light It selects, the size and thickness and openings of sizes etc. of cooling fin can be adjusted according to demand.

The utility model has the beneficial effects that radiating LED lamp provided by the utility model, lamp cap, which generates heat, to be passed through Top lamp cap heat is directed at protecgulum by the cooling fin of the design of Y types, and lamp cap central part heat is guided to cooling fin outer circumference end Face has carried out good drainage to hot-air around heat and radiating shell and has radiated, and radiating efficiency is high.

Specific implementation mode

The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.

A kind of radiating LED lamp as shown in Figure 1 to Figure 3 is the utility model optimum embodiment, including radiating shell 1. 1 interior sealing of the radiating shell is connected with lamp cap 2, and 2 outer end connection of the lamp cap has PCB lamp board, the radiating shell 1 Bottom surface is connected with protecgulum 3, then has reflector 4,4 inner surface of reflector tool in the radiating shell 1 between PCB lamp board There is concentric and radius gradually increased reflective raised line 5.Reflective raised line 5 can reflect light source, improve the utilization rate to light source.

1 peripheral radius of radiating shell gradually increases from top to bottom, and the 1 peripheral surface uniform intervals of radiating shell are fixed with Cooling fin 6, the cooling fin 6 are inverted Y types along 1 peripheral surface section of radiating shell, and the cooling fin 6 is along 1 bottom of radiating shell Facial plane direction section is Y types and radial open out, the heat dissipation centered on along 1 soffit plane center of radiating shell Piece 6 be combined with the opening portion of the Y types along 1 soffit plane direction of radiating shell along the Y types opening portion of 1 peripheral surface of radiating shell and Along the opening portion protrusion of the Y types in 1 soffit plane direction of radiating shell and along the Y types opening portion of 1 peripheral surface of radiating shell.

When work, lamp cap 2 generates heat and can be distributed by the outside heat exchange of radiating shell 1.The design of 1 surface of radiating shell dissipates Backing 6 can then be effectively increased the surface area of radiating shell 1, while the design of Y types, can lamp cap 2 heat in top be directed to protecgulum 3 Place, 2 central part heat of lamp cap are guided to 6 peripheral end face of cooling fin, have been carried out well to heat and 1 surrounding hot-air of radiating shell Drainage is conducive to improve radiating efficiency.

Further, in order to preferably increase by 1 surface area of radiating shell, improve radiating efficiency, adjacent two panels cooling fin 6 it Between radiating shell 1 on also have protrusion radiating ribs 7.Radiating ribs 7, will not be to the opening portion heat of Y types in the bottom of cooling fin 6 Air, which distributes, to cause to stream.

Preferably, cooling fin 6, radiating ribs 7 and radiating shell 1 are structure as a whole.The cooling fin 6 of integral structure, radiating ribs 7 It is completely embedded with radiating shell 1, can be convenient for generating the conduction of heat inside when work, improve radiating efficiency.

The radiating LED lamp so designed, lamp cap 2 generates heat can be by the cooling fin 6 of the design of Y types by top lamp cap 2 heats are directed at protecgulum 3, and 2 central part heat of lamp cap is guided to 6 peripheral end face of cooling fin, around heat and radiating shell 1 Hot-air has carried out good drainage heat dissipation, and radiating efficiency is high.
