Abstract

The utility model discloses a connection structure of LED light lamp shade and stem stem, it includes lamp shade and stem stem, it is little to set up an upper end diameter on the lamp shade pore wall, step hole that the lower extreme diameter is big, the lower terminal surface in this step hole contacts for annular terminal surface and stem stem terminal surface, the external diameter of annular terminal surface is greater than the diameter of stem stem upper end cylinder, arranges the lamp shade in when the stem stem in the time of on the annular terminal surface of step hole lower extreme, the annular chamber of formation holding bonding agent between the cylinder of stem stem upper end and the lamp shade pore wall, the bonding agent is filled out the cylinder and the interior adhesive layer that forms of the annular chamber between the lamp shade pore wall of stem stem upper end. The utility model has the advantages of energy -conservation, simple process, production efficiency height and high the showing of product percent of pass.

Description

A kind of attachment structure of LED illumination lamp lampshade and stem stem

Technical field:

This utility model relates to the packaging technology of a kind of illuminating lamp, the particularly lampshade of the LED filament lamp (lamp bead lamp) of a kind of evacuation, inflatable body and stem stem.

Background technology:

It is understood that LED lamp greatest problem is heat radiation, and the heat radiation of LED filament bulb (or LED lamp bead bulb) is dispelled the heat by lampshade outer surface mainly by being filled with special gas in lampshade. Being connected by heat-seal technique between current glass lamp shade and glass stem, this heat-seal technique, due to needs high-temperature heating, has following defects that 1. high intermediate temperature sealings affect the performance of LED lamp bar; 2. needing the operator of specialty glass processing, 3 adopt hot melts encapsulation, glass add can produce man-hour glass burn, the cold gas leak phenomenon such as quick-fried, affect conforming product rate; 4. because to be encapsulated in lamp be electric elements, so, sealing time and annealing time can not long, temperature is too high, such glass strain not easily eliminates; 5. the existence of glass strain, there will be after product sealing-in cold quick-fried and need Ageing Treatment have impact on conforming product rate extend installation time be unfavorable for continuous automatic production; 6. consume the energy and add cost.

Summary of the invention:

The attachment structure of a kind of LED illumination lamp lampshade that this utility model purpose is to provide and a kind of saves the energy, production technology is simple, production efficiency is high and qualification rate is high and stem stem.

The technical scheme realizing this utility model purpose is, a kind of attachment structure of LED illumination lamp lampshade and stem stem, it includes lampshade and stem stem, it is characterized in that: lampshade hole wall arranges a upper end diameter little, the stepped hole that lower end diameter is big, the lower surface of this stepped hole is that annular end face contacts with stem stem end face, the external diameter of described annular end face is more than the diameter of stem stem upper end cylinder, when on the annular end face that stem stem is placed in the described stepped hole lower end of lampshade, the annular chamber of accommodating bonding agent is formed between cylinder and the lampshade hole wall of stem stem upper end, bonding agent fills out formation bond layer in the annular chamber between the cylinder and lampshade hole wall of described stem stem upper end. described bonding agent is following any one: epoxide-resin glue, polyurethane adhesive, silica gel, phenolic resin glue, rubber glue, SGA, polyethylene glue and unsaturated polyester ester gum. described lampshade be shaped as following any one: spherical, tubular, pyriform, candle and olive shape.

This utility model has remarkable advantage energy-conservation, that technique is simple, production efficiency is high and conforming product rate is high compared with the prior art.

Accompanying drawing illustrates:

Fig. 1 is the attachment structure schematic diagram of this utility model LED illumination lamp lampshade and stem stem.

Detailed description of the invention:

For overcoming heat-sealable load between existing LED illumination lamp lampshade and stem stem to connect the defect of existence, existing LED filament lamp (lamp bead lamp) hot melt is encapsulated Problems existing and is analyzed by this utility model, if changing the hot melt packing forms that LED filament lamp (lamp bead lamp) is traditional, the technique adopting cold seal dress, except having stronger bonding strength, a cavity sealed must also be formed, make the air in cavity can be released by the air of lampshade cavity from exhaustor 5, the gas of conduction heat is charged into and air tight. Little by the hole wall in lampshade 2 port arranges a upper end diameter for this, the stepped hole that lower end diameter is big, the lower surface of this stepped hole is that annular end face contacts with stem stem 3 upper surface, and the external diameter of described annular end face is more than the diameter of stem stem upper end cylinder, when on the annular end face that stem stem is placed in the described taper hole lower end of lampshade, between cylinder and the lampshade hole wall of stem stem upper end, form the chamber of the annular of accommodating bonding agent. Bonding agent is filled out formation bond layer 7 in this annular chamber, and the structure of stem stem, driver 4, LED lamp bar 1, exhaustor 5 and lamp holder 6 is constant.

Described bonding agent is following any one: epoxide-resin glue, polyurethane adhesive, silica gel, phenolic resin glue, rubber glue, SGA, polyethylene glue and unsaturated polyester ester gum etc.

In order to meet the user's different demands to lampshade profile, the profile of described lampshade is following any one: spherical, tubular, pyriform, candle and olive shape etc.
