Detailed description of the invention

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

Refer to Fig. 1 and Fig. 2, it is the top exploded view of the radiating lamp of the utility model and looks up exploded view.The radiating lamp of the utility model comprises power connection seat 11, radiating seat 12, light emitting module 14, lens module 15 and retainer ring 16.Wherein, power connection seat 11 connects an external power source.Radiating seat 12 can connect power connection seat 11 by a Coupling 111, and radiating seat 12 can be arranged on this power connection seat 11.In radiating seat 12, comprise a housing 121, a plurality of curved fin 122 and a through hole ring 123, housing 121 is made by plastics and be provided with groove, and the madial wall of groove is embedded with metal base 1211, and plastics are to form housing 121; The surface of housing 121 lateral wall has a plurality of curved fin 122, and one end of a plurality of curved fin 122 connects bottom the outer wall of radiating seat 12, and can in structure wide at the top and narrow at the bottom; And wall port has through hole ring 123 outside housing 121, and the bottom vertical of through hole ring 123 ground connects the other end of a plurality of curved fin 122, and the surface of through hole ring 123 is provided with a plurality of holding section 1231.And light emitting module 14 is arranged in radiating seat 12, then lens module 15 is sheathed on above light emitting module 14.Further, the retainer ring 16 of radiating lamp can be arranged at above through hole ring 123, and corresponds to the position of a plurality of holding section 1231 and quantity arranges a plurality of Access Division 161 in the inner side of retainer ring 16.

The radiating seat 12 of the utility model is made by plastics, and these plastics are polyphenylene sulfide (Polyphenylene sulfide, abbreviation PPS), containing the polymer to phenylene sulfide constitutional repeating unit in its molecule, are a kind of new type functional engineering plastics.

The radiating lamp of the utility model can pass through beyond heat-radiation heat-dissipating, because radiating seat 12 madial wall is embedded with metal base 1211, more can dispel the heat by heat transfer, therefore can improve the effect of heat radiation, extend the life-span of general LED lamp.

Refer to Fig. 3 and Fig. 4, it is top view and the upward view of the radiating lamp of the utility model.As shown in Figure 3, the recessed convex surface 151 in exiting surface center of lens module 15, it can through cloudy surface process or in honeycomb type structure.And see it from depression angle, the outer rim of radiating lamp is provided with retainer ring 16, and its plurality of through holes that may correspond to through hole ring arranges a plurality of perforation 160 on retainer ring 16.Subsidiary one carries, and perforation 160 of the present utility model is arranged at the periphery of retainer ring 16 with rectangular configuration, after heat can be shed through the curved fin heat radiation of radiating seat, reach the effect of thermal convection current by a plurality of perforation 160.

As shown in Figure 4, it is seen from looking up angle, curved fin 122 stretches out from radiating seat center setting, and with counterclockwise bending, and the plurality of through holes 1232 of through hole ring 123 is arranged between each curved fin 122 respectively, the effect of thermal convection current can be increased by plurality of through holes 1232 when curved fin 122 dispels the heat.

Refer to Fig. 5 and Fig. 6, it is generalized section and the schematic appearance of the radiating lamp of the utility model.As shown in Figure 5, the lower surface of lens module 15 or can be honeycomb type structure through cloudy surface process, and its exiting surface center indent forms accommodation space 1501 on, and is provided with a convex surface 151 bottom upper accommodation space 1501.And convex surface 151 also can through cloudy surface process or in honeycomb type structure.Meanwhile, the incidence surface bottom lens module 15 indent can form accommodation space 1502.

See also Fig. 6, in figure, the curved fin 122 of radiating seat is in structure wide at the top and narrow at the bottom, and the top of a plurality of curved fin 122 bends in the same direction, and bending angle is all identical.One end of curved fin 122 is connected to sidewall bottom outside housing 121, and the other end is connected to the bottom of through hole ring 123.And the surface of power connection seat 11 has helical structure, go on various lamp socket.

The structure that curved fin 122 is bending can increase thermal-radiating area of dissipation, and is embedded with metal base in housing 121, makes radiating lamp can increase radiating rate by heat transfer, and the plurality of through holes set by through hole ring 123, can increase the effect of thermal convection current.

In sum, the radiating lamp through the utility model can shed in the mode of heat radiation and thermal convection current equably by the plurality of through holes set by curved fin and through hole ring.And, beyond the mode that can pass through heat radiation is dispelled the heat, also can pass through inner casing metal base conduction heat energy simultaneously, thermal conductance can be gone out by heat transfer by radiating lamp, fin can be made thus to avoid Yin Wendu inequality to cause fin that wherein a part of temperature is lower not play a role or usefulness reduces, and radiating lamp entirety can be made to increase heat dissipation, make it have preferably heat-conducting effect.

Certainly, the above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
