Description

A kind of LED

Technical field

This utility model is related to a kind of LED filament bulb.

Background technology

In prior art, ZL00268763.1 utility model patents disclose a kind of safety lamp holder, with reference to Fig. 1 institutes State safety lamp holder housing to be made up of glass insulator a2, lamp holder wall a3 and lamp connection member a6 etc., glass insulator a2 afterbodys set There are copper lamel a1, glass insulator a2 and glass dielectric layer a4 to be Contiuum type structure.During manufacture first on special grinding apparatus, copper Matter or the compacting of aluminum blank form the shell of lamp base being made up of lamp holder wall a3 and connection member a6, then apply on the inside of lamp holder wall a3 Upper tack coat a5, is placed in shell of lamp base bottom and has been placed with the particular manufacturing craft of copper lamel a1, by frit Jing high temperature meltings After change, instill in shell of lamp base, and hang along lamp holder wall, disjunctor is formed on the inside of shell of lamp base afterbody and lamp holder wall a3 after cooling The insulator a2 and insulating barrier a4 of formula.Judge from the above, the patent belongs to a kind of E14 types（Lamp holder diameter 14mm）Bulb, So because the part-structure of lamp holder wall is too little, it is impossible to be connected with bulb, can only be connected with bulb after connection member extends. The insulating barrier of above-mentioned bulb is as a result of glass machining technique；And prevent from coming off using tack coat fixed insulation layer, its material Cost and processing cost are high, are unfavorable for large-scale production.Because lamp connection member a6 can not accommodate driving power supply, therefore can not For LED filament bulb.

With the development of LED, the utility model patent LED of Patent No. ZL201510295878.7 is occurred in that on market The product of lamp, with reference to Fig. 2, the product belongs to a kind of E27 types（Diameter 27mm）Bulb.Because LED carries driving power supply, the reality An extension b3 is set up between the lamp holder b1 and bulb b2 of new patent（Equivalent to connector）, drive for placing LED Power supply, is additionally provided with top end socket and conducting strip at the top of the shell of lamp base（Equivalent to lamp holder lamel）.The extension b3 is adopted With moulding, its lower end directly bonds with the metal shell bonding of lamp holder, its upper end and glass bulb.

With the further development of electronic technology and semiconductor LED, the volume of electronic device is less and less, Patent No. The Chinese utility model patent of ZL201510130712.X, discloses a kind of " connectionless part LED bulb and its manufacture method ". The utility model patent is applied to small-sized LED drive power, when LED drive power is directly placed in lamp holder metal shell, After saving connector, Insulation Problems are generated between lamp holder and LED drive power.Solution is to set LED drive power Put in thermoplastic sleeve pipe, the thermoplastic sleeve pipe is the thermal contraction casing tube of a kind of special polyolefin or EVA material manufacture.Due to upper The characteristics of stating material is soft, insulation, elasticity, and can shrink after being heated, thus LED drive power is put into after heat-shrinkable T bush plus Heat, heat-shrinkable T bush shrinks wraps LED drive power, by the power input and outfan of LED drive power in advance from heat-shrink tube Two different mouths of pipe stretch out, facilitate follow-up lead.LED drive power after envelope modeling is arranged in the metal shell of lamp holder, Good insulating effect can be played.But, all it is manual operations due to above-mentioned whole production encapsulation process, it is not suitable for big rule The automated production enterprise of mould, and production cost is very high.Each LED drive power only packaging cost, including heat-shrinkable T bush into This labor cost with thermoplastic package, is greater than 0.15 yuan.Thus, for monthly output is in the large-scale of up to ten million LED bulbs Enterprise, cost is too high.

The content of the invention

The purpose of this utility model is to provide a kind of low production cost, the good LED bulb of insulation effect and its production technology.

This utility model purpose is achieved in that a kind of LED bulb, including lamp holder and LED drive power, the lamp holder Housing interior energy accommodates LED drive power, it is characterised in that：Insulated using injection machine injection one in the inner walls of the lamp holder Layer, the insulating barrier is molded integral with top end socket；The top end socket is provided with an aperture, and the aperture is provided with and it The conductive nail of cooperation.

The rivet nut of the conductive nail is provided with the bayonet socket coordinated with the aperture.

The thickness of the plastic insulating layer is 0.2-1.0mm

Less than the upper limb of lamp holder, its difference is 3-5mm to the upper limb of the plastic insulating layer.

Higher than the upper limb of lamp holder, it expands and upwardly extends the upper limb of the plastic insulating layer to surrounding.

The height of the extension is 3-5mm.

The utility model has the advantages that, directly it is molded in shell of lamp base using plastics, insulating barrier can be made relatively thin, and it is molded speed Degree is fast.And in shell of lamp base, whole LED driver circuit module can be accommodated, and production technology can be simplified, be conducive to being turned into automatically Industry, substantially increases production efficiency, reduces production cost.
