Abstract

The invention provides a light-emitting diode (LED) bulb which comprises a bulb holder piece and a heat dissipation shell. The big end of the bulb holder piece is fixedly connected with the small end of the heat dissipation shell through an embedding installation structure. In general, the small end of the heat dissipation shell is embedded in the big end of the bulb holder piece. The big end of the bulb holder piece is provided with a circular mortise. The small end of the heat dissipation shell is provided with a circular rabbet which is matched with the circular mortise. A locating boss is arranged on the big end face of the bulb holder piece, and a locating hole matched with the locating boss is formed in the small end face of the heat dissipation shell. The outer circle of the big end of the bulb holder piece is provided with a punch-pin hole which is guided to the circular mortise, and the circular rabbet on the small end of the heat dissipation shell is provided with a punch-pin which is stamped into the punch-pin hole. In lamps capable of replacing the drawing or stamping structure, other types of connection modes such as stamping glue or stamping a bolt are usually adopted. The LED bulb has the advantages of being simple to assemble, capable of being produced in a mechanized mode, time-saving, and confirm in connection. In addition, the LED bulb is not detachable, so that the potential safety hazard that a user gets an electric shock is avoided.

Description

A kind of LED bulb lamp

Technical field

The present invention relates to lighting technical field, relate in particular to the LED light-emitting device, more specifically say a kind of mounting structure of LED light-emitting device heat dissipation element.

Background technology

Because heat has very important impact to service life and the luminous efficiency of LED light fixture, so concerning the LED light fixture, heat dissipation design is particularly important, especially high-power LED lamp, for the good heat sinking function of realization system, generally can use aluminium alloy as the light fixture main body of dispelling the heat, improve the radiating effect of light fixture with this.

For the LED light fixture of E26/E27 lamp holder, the consideration from the secure context must have the part of plastic part or other non-metallic materials to be attached thereto and connect.

Between plastic part and the metal parts be fastenedly connected common way be screwed, be threaded, the mode such as glue is bonding, these modes assemble more time-consuming on the one hand, have on the other hand detachability, have for consumers certain danger, may cause electric shock.

Summary of the invention

The technical problem to be solved in the present invention is: for the deficiency that above-mentioned prior art exists, provide a kind of simple again lamp holder of safety and syndeton between the radiating piece of assembling.

The present invention addresses the above problem the technical scheme that proposes to be: a kind of LED bulb lamp, comprise lamp holder spare and radiation shell, and wherein the large end of lamp holder spare is fixedly connected with by the insert structure with the small end of radiation shell.The small end of radiation shell is embedded in the large end of lamp holder spare generally speaking.

The large end of lamp holder spare is provided with annular tongue-and-groove, and the small end of described radiation shell is provided with the annular tenon that matches with annular tongue-and-groove.Be provided with positioning boss on the large end face of lamp holder spare, be provided with the locating hole that matches with positioning boss on the small end face of described radiation shell.Be provided with the red needle hole of leading to annular tongue-and-groove on the cylindrical of the large end of lamp holder spare, be provided with the red needle of squeezing into from the red needle hole on the annular tenon of radiation shell small end.

Adopt technical scheme of the present invention, can replace in the light fixture of stretching or punching structure, usually adopt the connected mode of other patterns such as playing glue or screw.

Its advantage is: 1. assemble fairly simplely, can realize that mechanization produces in enormous quantities, greatly enhance productivity.Save time than other patterns such as playing glue or lock screw, it is firm to connect.

2. having after punching is riveted tightly can not demolition, dismantle and must destroy element, can guarantee like this user's use safety, avoids the user that the potential safety hazard of electric shock is arranged.

The specific embodiment

In order to make those skilled in the art person understand better technical scheme of the present invention, be described in further detail below in conjunction with drawings and Examples.

Shown in Figure 1 is the lamp holder spare 1 of the embodiment of a kind of LED bulb lamp of the present invention, adopts plastics to make.Shown in Figure 2 is the radiation shell 2 of the embodiment of the invention, adopts aluminium alloy to make.The large end of Plastic lamp socket spare 1 needs to be fixedly connected with by the insert structure with the small end of aluminium alloy radiation shell 2.And the small end of radiation shell 2 is embedded in the large end of lamp holder spare 1.

We are moulding one annular tongue-and-groove 1A on the large end at Plastic lamp socket spare 1 top, the annular tenon 2A that small end moulding one and the annular tongue-and-groove 1A in aluminium alloy radiation shell 2 bottoms matches.Simultaneously for preventing radiation shell 2 relative to the rotating of lamp holder spare 1, and on lamp holder spare 1 large end face four positioning boss 1B of moulding, moulding and four locating hole 2B that match with positioning boss 1B on the small end face of radiation shell 2.

As shown in Figure 3, Figure 4, the annular tenon 2A of radiation shell 2 bottoms is inserted in the annular tongue-and-groove 1A at lamp holder spare 1 top, simultaneously the locating hole 2B on the radiation shell 2 is aimed at the positioning boss 1B of lamp holder spare 1, finish and inlay installation.

In addition, we also form several red needle holes 1C at the cylindrical of lamp holder spare 1 large end, open to annular tongue-and-groove 1A place.

Behind the insert, by automatic pneumatic punching machine and be installed in custom-designed on this machine around with the punching jig of red needle, red needle around on the tool is passed several red needle holes 1C around the lamp holder spare 1, can automatically carry out punching and rivet tightly, with Plastic lamp socket spare 1 with the aluminium alloy radiation shell 2 firm riveting tightly be in the same place.

In the whole installation process, the annular tenon 2A of radiation shell 2 is inserted into lamp holder spare 1 and is inserted in the annular tongue-and-groove 1A and punching is riveted tightly, and is simple to operate, can be completely achieved automatic assembling, greatly saves labour turnover.Connect safe and reliablely, need to destroy and to remove, prevent that the user from can arbitrarily remove and cause potential safety hazard.

Be suitable for stretching in the LED light fixture of (punching press) formula structure, radiator shell is with the connection between the E26/E27 lamp holder, assembles fairly simplely, can realize that mechanization produces in enormous quantities, can Effective Raise production efficiency, save labour turnover; Security and reliability are high, do not have again detachability, have avoided the possibility of getting an electric shock concerning the consumer.

Foregoing is preferred embodiment of the present invention only, is not the present invention is carried out the scope restriction.Those skilled in the art can carry out corresponding flexible or modification very easily according to main design of the present invention and spirit.So protection scope of the present invention should be as the criterion with the covering scope of claim.
