Abstract

The invention relates to a ventilating lamp, which comprises a lamp holder, a lampshade, an electronic drive circuit and a light-emitting element, the lampshade comprises a basal body and a cover body, the basal body is mounted in the lamp holder, the outer surface of the basal body is provided with axially arranged ribs, the heads of the ribs are extended out of the basal body and abut against the stepped end surface in the lamp holder, the tails of the ribs are extended out of the basal body to reach the inclined surface of the cover body, the extended sections of the tails of the ribs are long enough so that a gap exists between the outer end surface of a big cylinder and the corresponding inclined surface of the cover body, and the outer surfaces of the ribs are tightly fixed on the inner wall of the large-aperture cylinder. Since the surface of the basal body is provided with the ribs arranged at intervals and one end of each rib abuts against the stepped end surface in the lamp holder and the other end of each rib abuts against the inclined surface of the cover body, the basal body is respectively separated from the stepped surface of the lamp holder and the inclined surface of the cover body, so that ventilating passages are formed in between, consequently, the heat generated by the electronic drive circuit and the light-emitting element in operation can be effectively and quickly released via the ventilating passages, and thereby the stability in use is enhanced.

Description

Ventilating lamp

Technical field

The present invention relates to a kind of ventilating lamp, be specially adapted to the light fixture of LED (light emitting diode) as illuminator.

Background technology

Existing ordinary lamp and lantern includes lamp socket, lampshade, electronic drive circuit and light-emitting component, and 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 are unstable under the condition of high temperature, and very easily damage, thus the service life of having reduced product.

Summary of the invention

In order to overcome the deficiency that serviceability is unstable, the life-span is short that existing light fixture exists, the present invention provides a kind of ability timely distribute heat, and serviceability is stable, the ventilating lamp that the life-span is long.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of ventilating lamp includes lamp socket, lampshade, electronic drive circuit and light-emitting component, and said 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 supplies lead to run through; Small cylinder inner face and large cylinder inner face are through step transition, and light-emitting component is electrically connected through lead with power supply, and said lampshade includes the matrix of head and the cover body of afterbody; Said matrix is installed in the lamp socket; Outer surface of matrix is provided with axial arranged prominent muscle, and the head of prominent muscle extends matrix and offsets with step end face in the lamp socket, and 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 said lampshade and lamp socket also adds and is stained with glue.

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

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

Beneficial effect of the present invention mainly shows: between 1, matrix surface is provided with or the prominent muscle of arranging; And the two ends of prominent muscle extend out respectively, and step end face offsets in an end and the lamp socket; The inclined-plane of one end and cover body offsets; Matrix breaks away from lamp socket step surface, cover body inclined-plane respectively, thereby has produced the gap, between the adjacent prominent muscle, between matrix and the lamp socket step surface and formed gas-permeable channels between matrix and the cover body inclined-plane; The heat that electronic drive circuit and light-emitting component work produce obtains discharging effectively fast through 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 an overall structure sketch map of the present invention;

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 present invention is further described.

With reference to Fig. 1, a kind of ventilating lamp includes lamp socket, lampshade, electronic drive circuit and light-emitting component 1; Said 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 supplies lead to run through, and small cylinder inner face and large cylinder 4 inner faces are through step transition, and light-emitting component is electrically connected through lead with power supply; Said lampshade includes the matrix 5 of head and the cover body 6 of afterbody; Said matrix is installed in the lamp socket, and outer surface of matrix is provided with eight groups of axial arranged prominent muscle 7, symmetrical sheet; 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, and 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 said lampshade and lamp socket also adds and is stained with glue.The large cylinder outer face of said lamp socket is globoidal structure.
