Abstract

The utility model provides an LED lamp body structure including a lamp holder, a radiator, an extrusion member, a fixing plate and a lampshade, wherein one end of the lamp holder is an access end of an external power supply, and the other end of the lamp holder extends to form an integral hollow insulation sleeve, of which the external wall is provided with a plurality of notches. The radiator comprises a plurality of heat radiation fins, the upper ends of the heat radiation fins correspond respectively to notches of the insulation sleeve, and the lower ends of the heat radiation fins correspondingly clamped on the extrusion member. Notches cooperative with the heat radiation fins are arranged on the external wall of the extrusion member. The fixing plate where an LED luminous element is installed is arranged under the extrusion member. The lampshade is installed under the fixing plate for correspondingly covering an LED luminous element.

Description

A kind of LED lamp body structure

Technical field

The utility model relates to the field of light fixture, specifically is relevant with a kind of LED lamp body structure.

Background technology

The lamp holder of tradition LED lamp, as shown in Figure 1, form by lamp holder 1 ', radiator 2 ', aluminium base 3 ' and LED light-emitting component 4 ', establish a cavity volume in the radiator 2 ', for a driver (not shown) is installed, this lamp socket 1 by the spiro connecting piece screw lock on radiator 2 ', aluminium base 3 ' screw lock is in the below of radiator 2 ', and this LED light-emitting component 4 ' is located on the aluminium base 3 ' and is electrically connected this driver, after the energising, luminous by driver control LED light-emitting component 4 ', reach the illumination effect.。

Above-mentioned structure, because this driver is to be installed on the radiator 2 ', cause easily between driver and metal radiator 2 ' and be short-circuited, and then shorten the LED lamp problem in service life, in view of this, the design people constantly studies the improvement creative ideas based on product, and actively research and development thinking with great concentration has generation of the present utility model eventually.

The utility model content

The purpose of this utility model is to provide a kind of LED lamp body structure, commonly uses the LED lamp with solution and causes the problem that is short-circuited between driver and metal system radiator easily.

For reaching above-mentioned purpose, technical solution of the present utility model is:

A kind of LED lamp body structure, by lamp holder, radiator, extrude part, fixed head and lampshade and form, one end of described lamp holder is the incoming end of external power source, the then outside one of the other end extends to form the insulating sleeve of a hollow can control the luminous driver that illuminates of LED light-emitting component for installing one, and the outer wall of this insulating sleeve is laid with plural draw-in groove around circumference; Described radiator is made up of plurality of radiating fins, and this radiating fin is provided with perforation, the upper end corresponding stopper of difference of each radiating fin is on the draw-in groove of this insulating sleeve, lower end then correspondence is snapped in this and extrudes on the part, but this extrudes the draw-in groove that also is laid with each radiating fin of corresponding matching on the outer wall of part; Described fixed head is located at this below of extruding part, and the LED light-emitting component is installed on it, and this LED light-emitting component is electrically connected to the driver in this insulating sleeve; Described lampshade is installed on corresponding this LED light-emitting component of cover cap in below of fixed head.

Further, be provided with an ash-stopping ring between this lampshade and fixed head.

Adopt such scheme, utilize the insulating sleeve of integrated hollow on the lamp holder, the driver of order control LED light-emitting component is installed in this insulating sleeve, can effectively avoid the phenomenon that is short-circuited between driver and metal radiator, improve the service life of LED lamp, in addition, the upper and lower end of each radiating fin of this radiator be corresponding respectively stopper in this insulating sleeve outer wall and this extrude the part outer wall draw-in groove on, greatly facilitate the manufacturing and the installation of radiating fin.

The specific embodiment

Cooperate shown in Fig. 2,3,4, be a kind of LED lamp body structure of the utility model schematic diagram, its mainly by lamp holder 1, radiator 2, extrude part 3, fixed head 4 and lampshade 5 and form.

A wherein end of this lamp holder 1 is as the incoming end 11 of external power source, the then outside one of the other end extends to form the insulating sleeve 12 of a hollow, can can control the luminous driver (not shown) that illuminates of LED light-emitting component for installing one in this insulating sleeve 12, and the outer wall of this insulating sleeve 12 is laid with plural draw-in groove 13 around circumference, this radiator 2 is made up of plurality of radiating fins 21, and this radiating fin 21 is provided with perforation 211, the upper end of each radiating fin 21 corresponding stopper of difference is on the draw-in groove 13 of this insulating sleeve 12 during installation, lower end then correspondence is snapped in this and extrudes on the part 3, but also be laid with the draw-in groove 31 of each radiating fin 21 of corresponding matching on the same outer wall of extruding part 3, this makes radiating fin 21 be laid in the periphery of this insulating sleeve 12 by this; This fixed head 4 is located at the below that this extrudes part 3, LED light-emitting component (not shown) is installed on it, this LED light-emitting component is electrically connected to the driver in this insulating sleeve 12, make the LED light-emitting component under the control of driver, realize luminous illuminating, this lampshade 5 is installed on corresponding this LED light-emitting component of cover cap in below of fixed head 4, and the utility model also can be provided with an ash-stopping ring 6 at this lampshade 5 and 4 of fixed heads, guarantees the effect that illuminates of LED light-emitting component.

The utility model LED lamp body adopts said structure, utilize the insulating sleeve 12 that forms a hollow on the lamp holder 1, the driver of order control LED light-emitting component is installed in this insulating sleeve 12, can effectively avoid the phenomenon that is short-circuited between driver and metal radiator, improve the service life of LED lamp, in addition, the upper end corresponding stopper of difference of each radiating fin 21 of this radiator 2 is on the draw-in groove 13 of these insulating sleeve 12 outer walls, the lower end is then corresponding to be snapped on this draw-in groove 31 of extruding part 3 outer walls, greatly facilitates the manufacturing and the installation of radiating fin 21.
