Description

A kind of LED bulb being readily produced

Technical field

The utility model relates to a kind of illuminator, especially a kind of LED bulb being readily produced.

Background technique

Currently, LED bulb generally comprises lamp cap and wick column, and wick column is by metal one drawing and forming, the side of wick column Wall and top are pasted with LED light source, and wick column is connected through a screw thread the top that mode is mounted on lamp cap, internal to form sealing sky Between, the driver of light bulb is mounted in sealing space, therefore, when producing wick column, needs to be arranged one at the top of wick column Wire guide is electrically connected by driver with LED light source, is caused the die casting for producing wick column to become complicated, is greatly increased LED The production cost of light bulb, and since wick column is made of metal material, the driver inside wick column is needed using insulation Gummed paper is wrapped up, and prevents that electric shock accidents occurs when human contact's light bulb, so that the assemble flow of LED bulb is more cumbersome, Extend the production cycle of LED bulb, in addition, the heat that LED bulb generates can accumulate in lamp because being sealing space inside wick column In stem, driver is caused to be easy to happen high temperature damaged phenomenon, reduces the service life of LED bulb.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provide it is a kind of it is highly-safe, heat dissipation is good, is readily produced LED bulb.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of LED bulb being readily produced, including lamp cap, lamp holder and wick column, the lamp cap are mounted on the lamp holder Bottom, the side wall of the wick column and top are pasted with LED light source, and light source drive, the wick are equipped in the lamp holder Column is the tubular that sheet metal punching press is constituted, and is provided with internal ring wall at the top of the lamp holder, the wick column by with the inner ring Wall transition fit is mounted on the top of the lamp holder, and the side of the internal ring wall is provided with metallic channel.

Wick column's outer sheath is equipped with lampshade, is provided with external annulus at the top of the lamp holder, the bottom of the lampshade is set It is equipped with connection annulus, the medial surface of the external annulus is provided with the annular groove for fastening the connection annulus.

Heat release hole is provided at the top of the lampshade.

For the lamp holder by plastic extruding forming, the bottom of the lamp holder is provided with fixed step, the bottom surface of the lamp holder and Several gas ports are provided on the terrace of fixed step.

Gas vent is provided at the top of the wick column.

The beneficial effects of the utility model are: what the utility model wick column was made of the simple punching press of the sheet metals such as aluminium, iron Tubular structure part optimizes the production technology of light bulb and can lower its production cost, lamp holder without using complicated die casting The internal ring wall at top is provided with metallic channel, and light source drive can be directly electrically connected by metallic channel with LED light source using conducting wire, nothing Wire guide need to be additionally opened up in wick column, lamp holder can be effectively prevent occurring when human contact's light bulb by plastic extruding forming Electric shock accidents, internal light source drive carry out insulation package processing without using insulation gummed paper, simplify assemble flow, light bulb On gas port, gas vent and heat release hole, allow light bulb inside be no longer a sealing space, extraneous cold air can lead to It crosses stack effect and efficiently absorbs the heat waste rate that the heat that LED bulb generates greatly reduces LED bulb, extend the use of light bulb Service life.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.
