Abstract

The utility model discloses a large-power LED energy-saving lamp with excellent radiation performance. The large-power LED energy-saving lamp comprises a lamp head and a lamp cover, wherein the lamp head is wholly of a cylinder structure, the rear end of the lamp head is connected with a lamp base, a large-power LED light source is installed at the front end of the lamp head, the front end of the lamp head extends into the lamp cover, the lamp cover is in a sealed transparent semispherical shape, the periphery of the lamp head is wrapped by the radiating fins, the radiating fins are of annular structures, the plurality of radiating fins are arranged in the direction from the front end of the lamp head to the rear end of the lamp head, the outer diameter of the radiating fins decreases gradually, and annular air channels are formed between the radiating fins. Furthermore, a thread is manufactured at the periphery of the rear end of the lamp head.

Description

High-power LED energy-saving lamp

Technical field

The utility model relates to a kind of LED electricity-saving lamp, is specifically related to a kind of high-power LED energy-saving lamp.

Background technology

In the situation that current global energy growing tension, each state is all energy-conservation in promotion, and finds various energy saving ways; Wherein, LED(light emitting diode) because it is energy-conservation, the life-span is long, light efficiency is high, the advantage such as radiationless, shock resistance, and get most of the attention.

The current use of LED electricity-saving lamp is comparatively general, although the LED electricity-saving lamp belongs to cold light source, himself can produce heat, and temperature can produce on the performance of LED lamp itself impact greatly; The power of existing LED electricity-saving lamp is less, and this is mainly to worry that excessive power can cause dispelling the heat bad, and also there is the phenomenon of too early excessive light decay really in the actual high-power LED energy-saving lamp used.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of high-power LED energy-saving lamp of excellent radiation performance for above-mentioned deficiency of the prior art.

The utility model solves the technical scheme that its technical problem adopts: high-power LED energy-saving lamp, comprise lamp holder and lampshade, lamp holder integral body is cylindrical structure, the rear end of lamp holder is for connecting lamp socket, the front end of lamp holder is equipped with high-power LED light source, lamp base front end is deeply to lampshade inside, and lampshade is airtight transparent hemisphere shape;

The excircle parcel of lamp holder arranges fin, and fin is cirque structure, the direction of a plurality of fin along lamp base front end to rear end, and its external diameter reduces gradually; Form the air-guiding aisle of annular between a plurality of fin.

Further: on the excircle of the rear end of above-mentioned lamp holder, be manufactured with screw thread.

The utility model compared with prior art has the following advantages:

The utility model high-power LED energy-saving lamp, the heat radiation of whole electricity-saving lamp adopts spaced apart annular fin, because the quantity of fin is many, therefore can carry out high efficiency and heat radiation, meanwhile, the spaced apart mode of annular fin, make between a plurality of annular fin and formed the passage for generation of the annular of good Air Flow; Make the thermal diffusivity of whole LED electricity-saving lamp be greatly improved, therefore can adopt reliably high-power LED light source to be thrown light on.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model specific embodiment is described:

Fig. 1 shows a kind of concrete structure of the present utility model, as shown in the figure, the utility model high-power LED energy-saving lamp, comprise lamp holder 3 and lampshade 1, lamp holder 3 integral body are cylindrical structure, and the rear end of lamp holder 3 is for connecting lamp socket, and the front end of lamp holder 3 is equipped with high-power LED light source, lamp holder 3 front ends are deeply to lampshade 1 inside, and lampshade 1 is airtight transparent hemisphere shape;

The excircle parcel of lamp holder 3 arranges fin 2, and fin 2 is cirque structure, the direction of a plurality of fin 2 along lamp holder 3 front ends to rear end, and its external diameter reduces gradually; Form the air-guiding aisle of annular between a plurality of fin.

Concrete, be manufactured with screw thread on the excircle of the rear end of above-mentioned lamp holder 3.

The above is explained in detail the utility model preferred embodiment by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.

Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
