Abstract

The utility model relates to a breathable light fixture comprising a lamp holder, a lampshade, an electronic drive circuit and a luminous element. The lampshade comprises a base body and a shade body, whereby the base body is disposed in the lamp holder and a projecting rib is axially disposed on the outside surface of the base body. The head of the projecting rib extends out of the base body and abuts against the step side surface, and the trail part of the projecting rib extends out of the base body to the inclined plane of the base body. The extending part of the trail part of the projecting rib is big enough to allow a clearance between the outer side surface of the big cylinder and the inclined plane with respect to the shade body, and the outside surface of the projecting rib is tightly fixed on the inner wall of the cylinder with large aperture. In the utility model, the projecting rib is disposed on the surface of the base body at intervals, whereby one end of the projecting rib abuts against the inner step side surface of the lamp holder, and the other end abuts against the inclined plane of the shade body. The base body is separated from the step side surface of the lamp holder and the inclined plane of the shade body to form a breathable channel, through which the heat caused by the electronic drive circuit and the luminous element can be eliminated quickly and effectively, so that the stability of the product can be raised.

Description

Ventilating lamp

Technical field

The utility model relates to a kind of ventilating lamp, is specially adapted to the light fixture of LED (light emitting diode) as illuminator.

Background technology

Existing ordinary lamp and lantern, include lamp socket, lampshade, electronic drive circuit and light-emitting component, electronic drive circuit and light-emitting component are arranged in the lampshade, the general screw thread of lampshade is installed in the lamp socket, and both do not have the slit between the joint face, and the heat that produces when electronic drive circuit and light-emitting component work reaches between lamp socket and the lampshade, heat is difficult for distributing, properties of product instability under the condition of high temperature, and very easily damage, thereby the service life of having reduced product.

Summary of the invention

In order to overcome serviceability instability, the short deficiency of life-span that existing light fixture exists, the utility model provides a kind of energy timely distribute heat, and serviceability is stable, the ventilating lamp that the life-span is long.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of ventilating lamp, include lamp socket, lampshade, electronic drive circuit and light-emitting component, described lamp socket comprises the hollow circular cylinder that does not wait in two sector holes footpath, small cylinder outer face wherein offers the through hole that runs through for lead, small cylinder inner face and large cylinder inner face pass through step transition, light-emitting component is electrically connected by lead with power supply, described lampshade includes the matrix of head and the cover body of afterbody, described matrix is installed in the lamp socket, outer surface of matrix is provided with axial arranged prominent muscle, the head of prominent muscle extends matrix and offsets with step end face in the lamp socket, the afterbody of prominent muscle extends matrix on the cover body inclined-plane, the afterbody extension length of prominent muscle enough makes between the inclined surface of large cylinder outer face and cover body and leaves the gap, and the outer surface and the large aperture section cylinder inwall of the muscle of dashing forward closely cooperate fixing.

The end face that is connected of described lampshade and lamp socket also adds and is stained with glue.

The large cylinder outer face of described lamp socket is globoidal structure.

The prominent muscle of described basic surface is eight groups, symmetric arrangement.

The beneficial effects of the utility model mainly show: 1, between matrix surface is provided with or the prominent muscle of arranging, and, the two ends of prominent muscle extend out respectively, step end face offsets in one end and the lamp socket, the inclined-plane of one end and cover body offsets, matrix respectively with the lamp socket step surface, the cover body inclined-plane breaks away from, thereby produced the gap, between the adjacent prominent muscle, formed gas-permeable channels between matrix and the lamp socket step surface and between matrix and the cover body inclined-plane, the heat that electronic drive circuit and light-emitting component work produce obtains discharging effectively fast by this gas-permeable channels, has improved stability in use; 2, improved service life, reduced production cost; 3, simple in structure, cost of manufacture is high, result of use is good.

Description of drawings

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is matrix and prominent muscle structural representation;

Fig. 3 is the A-A enlarged drawing of Fig. 1.

The specific embodiment

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

With reference to Fig. 1, a kind of ventilating lamp, include lamp socket, lampshade, electronic drive circuit and light-emitting component 1, described lamp socket comprises the hollow circular cylinder that does not wait in two sector holes footpath, small cylinder 2 outer faces wherein offer the through hole 3 that runs through for lead, small cylinder inner face and large cylinder 4 inner faces pass through step transition, light-emitting component is electrically connected by lead with power supply, described lampshade includes the matrix 5 of head and the cover body 6 of afterbody, described matrix is installed in the lamp socket, outer surface of matrix is provided with eight groups of axial arranged prominent muscle 7, symmetric arrangement, the head of prominent muscle extends matrix and offsets with step end face in the lamp socket, the afterbody of prominent muscle extends matrix on the cover body inclined-plane, the afterbody extension length of prominent muscle enough makes between the inclined surface of large cylinder outer face and cover body and leaves the gap, and the outer surface and the large aperture section cylinder inwall of the muscle of dashing forward closely cooperate fixing.The end face that is connected of described lampshade and lamp socket also adds and is stained with glue.The large cylinder outer face of described lamp socket is globoidal structure.
