Description

A kind of bulb lamp with dust reduction capability

Technical field

The utility model is related to field of lamp illumination, more particularly to a kind of bulb lamp with dust reduction capability.

Background technology

LED is increasingly favored because of the characteristic with long lifespan, energy-conserving and environment-protective and without mercury pollution by people.And because For LED because its shape and light emitting species are all close with the incandescent lamp and electricity-saving lamp that people's tradition is used, therefore application is more extensive. Most of existing bulb lamp is made up of lamp holder, lamp housing, aluminium base, radiator and LED, and radiator is connected with aluminium base will The heat transfer that LED is produced is gone out, and reaches radiating effect.The radiator of bulb lamp is traditionally arranged to be gear-like, and surface is all provided with There is radiating fin, such a design radiating effect is preferable, but the design of radiating fin causes radiator to be highly prone to the dirt of dust Dye, influences radiating effect and cleans more to bother, especially when such a light fixture is used in workshop etc..

Utility model content

Based on this, the purpose of this utility model is to overcome the defect of prior art there is provided a kind of with dust reduction capability Bulb lamp, the utility model is achieved through the following technical solutions above-mentioned purpose：

The utility model provides a kind of bulb lamp with dust reduction capability, including lamp holder 1, radiator 2, the first lampshade 3 And LED component, the radiator 2 is connected through a screw thread with lamp holder 1, and the lampshade 3 of radiator 2 and first passes through the screw thread of middle ring 4 Connection, the LED component is located between the lampshade 3 of radiator 2 and first and is fixed on radiator 2, and the radiator 2 is gear Shape, surface is evenly equipped with radiating fin, it is characterised in that also including being arranged the second lampshade 5 on a heat sink, second lampshade 5 include spiral helicine dustproof construction 51 and the tubaeform reflective structure 52 positioned at its underpart, the spiral of the dustproof construction 51 Piece is stacked gradually and tilted down.

Preferably, the top of reflective structure 52 is symmetrically arranged with some projections 54 for fixing the second lampshade 5, the projection 54 inlay cards are between two adjacent radiating fins.

Specifically, the projection 54 has four.

Preferably, the radiating fin of the radiator 2 is up-thin-low-thick structure, and the inlay card of projection 54 is on thinner top 21 and the junction of thicker bottom 22.

Preferably, the diameter of the upper opening of the dustproof construction 51 is less than the diameter on the top of radiator 2.

Preferably, the dustproof construction 51 and reflective structure 52 are made up of disposable compression moulding.

Preferably, the internal coat of the reflective structure 52 has reflectorized material.

The utility model provides a kind of bulb lamp with dust reduction capability, and a top is arranged on a heat sink for spiral The dustproof construction of shape and bottom are the second lampshade of horn-like reflective structure, and the flight of dustproof construction is tilted down, and is made The light that obtaining whole light fixture can be sent in use reflexes to bottom, improves the utilization rate of light, can be prevented effectively from again Radiating fin is vulnerable to dust pollution, the situation of influence radiating effect；Dustproof construction is arranged on a heat sink by projection etc., side Just cleaning is removed.

Embodiment

Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings：

As shown in figure 1, the bulb lamp with dust reduction capability described in the present embodiment, including lamp holder 1, radiator 2, the first lamp Cover 3 and LED component, radiator 2 are gear-like, and surface is evenly equipped with radiating fin, the two ends of radiating fin and is provided with screw thread, its One end is together by a threaded connection with lamp holder 1, and the other end is threaded togather by middle ring 4 with the first lampshade 3, LED groups Part is located between the lampshade 3 of radiator 2 and first, and is screwed on radiator, specifically refer to prior art.

The bulb lamp with dust reduction capability described in the present embodiment, as shown in Fig. 2 also including being arranged the on a heat sink Two lampshades 5, the second lampshade 5 includes spiral helicine dustproof construction 51 and the tubaeform reflective structure 52 positioned at its underpart, dust-proof The flight of structure 51, which is stacked gradually, to be tilted down so that dust not easily passs through spiral helicine dustproof construction 51 and entered on radiator Radiating fin between, influence radiator 2 radiating effect；Further, by the interior ring design of spiral helicine dustproof construction 51 Contacted for the radiating fin with radiator 2, more preferable radiating effect can be reached, and dustproof construction 51 is designed as flight spiral Form, the radiating of the radiating fin of radiator 2 is not influenceed.

The bulb lamp with dust reduction capability described in the present embodiment, as shown in figure 4, on the reflective structure 52 of the second lampshade 5 Portion is symmetrically arranged with four projections 54 for fixing the second lampshade, projection 54 just can inlay card two adjacent radiating fins it Between.Further, the radiating fin of radiator 2 can be designed as to up-thin-low-thick structure, it is thinner that projection 54 can extend into top Radiating fin between and can not stretch between the thicker radiating fin in bottom, i.e., the width of projection 54 is less than the thinner phase in top The distance between adjacent two radiating fins and the distance between two neighboring radiating fin thicker more than bottom so that projection 54 Inlay card is in the junction of thinner top 21 and thicker bottom 22 so as to realizing the fixation of the second lampshade.

Further, the diameter of the annular opening 53 of the topmost of dustproof construction 51 is less than the diameter on the top of radiator 2, makes Obtaining the second lampshade 5 can be fixed on lamp body.

The bulb lamp with dust reduction capability described in the present embodiment, the second lampshade 5 is dustproof construction 51 and reflective structure 52 It is made up, is simple to manufacture of disposable compression moulding, and the internal coat of reflective structure 52 has reflectorized material so that it has more preferable Reflecting effect.

The utility model is not limited to above-mentioned preferred forms, all made with this reality under enlightenment of the present utility model With new same or like scheme, each fall within protection domain of the present utility model.
