Abstract

The utility model relates to the field of lighting lamps, in particular to a hardware stamping light emitting diode (LED) bulb lamp comprising a lamp cap component, a plastic connecting piece, a metal radiating shell body, an LED aluminum substrate module and a glass lamp shade which are integrated; and convex ribs are arranged on a casing of the metal radiating shell body. The aluminum radiating shell body of a traditional LED bulb lamp is molded through an aluminum alloy sections lathe machining process or an aluminum alloy die casting process and is changed to be molded through a hardware stamping process, so that the radiating shell of a finished product has the advantages of light weight, low cost and good radiating performance.

Description

A kind of hardware stamping LED bulb lamp

Technical field

The utility model relates to field of illuminating lamps, relates in particular to a kind of hardware stamping LED bulb lamp.

Background technology

Along with the development of LED technology, on the market LED demands of applications is also increased day by day, the application of all kinds of LED bulb lamps is also more and more.Produce a large amount of heats when working, so the design of radiator structure has been proposed more and more higher requirement because of LED.

The aluminium radiating shell of traditional LED bulb lamp causes the radiating shell of finished product thicker by aluminium alloy extrusions machined into technology or aluminum alloy die-casting technological moulding, so cause the shortcoming that quality is big, cost is high, heat dispersion is not good.These shortcomings of the radiating shell of producing at traditional handicraft are necessary to design a kind of LED bulb lamp of more energy-conserving and environment-protective.

The utility model content

In order to overcome the deficiency of the radiating shell that prior art makes, the utility model provides a kind of light weight, cost is low and the hardware stamping LED bulb lamp of perfect heat-dissipating.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of hardware stamping LED bulb lamp, in conjunction with forming, the shell of described heat dissipation metal housing is provided with convex tendon by lamp adapter assembly, plastic fastening, punching press radiating shell, LED aluminium base module and glass lamp shade.

As optimize selecting, the shell of described plastic fastening is provided with the convex tendon of the convex tendon inner concave interference fit on the shell with the punching press radiating shell.

Select the opening of described punching press radiating shell and LED aluminium base module interference fit as optimizing.

Select as optimizing, described punching press radiating shell is the aluminium alloy radiating shell.

Select as optimizing, the convex tendon quantity of described punching press radiating shell is not one, and is evenly distributed on the shell.

Select as optimizing, the quantity of the convex tendon of described plastic fastening is one.

Select as optimizing, the convex tendon of described punching press radiating shell is vertical.

Punching press radiating shell of the present utility model has adopted the compacting of hardware stamping moulding process to form, so the thickness of finished product is extremely thin, can quicken housing and the extraneous speed that heat exchange takes place, and has light weight, saves material, reduces cost the good advantage of dispelling the heat; And have equally distributed many convex tendons on the housing, and increased housing and extraneous contact area, promptly increased area of dissipation, so heat dispersion is very good; Also have, the opening portion of radiating shell is to adopt the mode of interference fit to be connected with LED aluminium base module, so both combinations are very tight, guaranteed nonseptate being transmitted on the radiating shell of heat that LED aluminium base module produces, thereby can further improve the heat dispersion of LED bulb lamp.

1. lamp adapter assemblies among the figure, 2. plastic fastening, 3. plastic fastening convex tendon, 4. aluminium alloy radiating shell, 5.LED aluminium base module, 6. glass lamp shade, 7. aluminium alloy radiating shell convex tendon, 8. aluminium alloy radiating shell opening.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, be a kind of hardware stamping LED bulb lamp of the present utility model, comprised lamp adapter assembly 1, be installed in the plastic fastening 2 on the lamp adapter assembly 1, be socketed in the aluminium alloy punching press radiating shell 4 on the plastic fastening 2, force to be pressed into the LED aluminium base module 5 and the glass lamp shade 6 that is installed on the LED aluminium base module of aluminium alloy radiating shell opening 8 by outer mold, lamp adapter assembly and glass lamp shade all are the parts of the conventional shape bought on the existing market, as the lamp adapter assembly employing is the E26 model, here just lamp adapter assembly and glass lamp shade have not been described in detail, existing in conjunction with describing in detail with the close relevant assembly of the utility model.Aluminium alloy punching press radiating shell 4 is made by the hardware stamping moulding process, and on the shell of radiating shell, be provided with equally distributed many vertical convex tendons 7, the aluminium alloy radiating shell thickness that is stamped to form is 1mm, whole height is 50mm, and aluminium alloy radiating shell opening 8 is 2, and an end is bigger, one end is less, the diameter of big opening is 60mm, and the diameter of smaller opening is 30mm and than the slightly larger in diameter of plastic fastening 2, and height of its big opening is 4.5mm; Be provided with on the shell of plastic fastening 2 one can with the dispel the heat convex tendon 3 of shell convex tendon 7 interference fit of aluminium alloy, the quantity that plastics connect convex tendon 3 can not be one also, during use, plastic fastening 2 is after assembling with aluminium alloy radiating shell 4, the inner concave interference fit of plastic fastening convex tendon 3 and aluminium alloy radiating shell convex tendon 7, it is firmly firm to have guaranteed to connect; LED aluminium base module 5 adopts interference fit to be connected with aluminium alloy radiating shell 4, LED aluminium base module 5 is forced to be pressed into the big opening portion of aluminium alloy radiating shell opening 8 by outer mold, make LED aluminium base module 5 and 4 seamless links of aluminium alloy radiating shell together, make both firmly fixing, during LED work, guaranteed nonseptate being transmitted on the aluminium alloy radiating shell of heat that LED aluminium base module 5 produces.

Described embodiment is a kind of optimizing structure of the present utility model, and the material of aluminium alloy heat radiation shell also can be other metal materials, for example aluminium, iron etc.; Convex tendon quantity, distribution or the shape of radiating shell can change by actual demand, not necessarily evenly distribution or vertical; The making parameter of radiating shell also can be set according to actual conditions; So common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
