Accompanying drawing explanation
Fig. 1 is that the structure of the utility model embodiment forms schematic diagram.
The specific embodiment
Following examples are further described the utility model in connection with accompanying drawing.
Referring to Fig. 1, the utility model embodiment is provided with glass bulb 1, light emitting diode 2, auxiliary electrode 4, interior electrode 5, stem stem 6, blast pipe 8 and external electrode and quotes line 9.Described light emitting diode 2, auxiliary electrode 4, interior electrode 5 and stem stem 6 are located in glass bulb 1, the two ends of light emitting diode 2 are fixed on stem stem 6 tops by interior electrode 5, auxiliary electrode 4 is fixed on stem stem 6, and one end that external electrode is quoted line 9 is connected with interior electrode 5, is filled with heat-conducting gas 3 in glass bulb 1; Blast pipe 8 is located on stem stem 6 and passes glass bulb 1 outside.
Described glass bulb 1 adopts pears type clear bulb.
Described light emitting diode 2 adopts by 2 lamp stripe shape light emitting diode combined.
The opening encapsulation of the horn mouth of described stem stem 6 and glass bulb 1.
Manufacturing process of the present utility model, majority is implemented by the lamp mode processed of traditional common bulb and gas-discharge lamp, and difference is part material, as: the Penning effect gas of LED, helium and the zinc-plated auxiliary electrode of iron etc.When technologic feature is sealing, flame heating surface (area) (HS is little, delivery temperature is low, the blowing pressure is high.
Stem stem of the present utility model can be produced by the stem stem mode of the solid stalk stem stem of common bulb band of the prior art and discharge lamp.Different is seal wire the inner can be cheap galvanized wire or copper wire etc., but can not become with the fused Dumet wire of glass.
While shelving, LED is combined to spot welding or scolding tin on the electrode of stem stem, and arrangement mode needs by light projector angle and carries out geometry arrangement, controls the arcing distance that has place's minimum between positive and negative, regulation and control, apart from size, make discharge breakdown magnitude of voltage be slightly larger than the total working voltage of LED group.Adopt the LED inflation bubble of glow discharge electrode to tune up aura apart from size as far as possible, control glow voltage and be less than
after having shelved, to carry out Ultrasonic Cleaning.
The sealing of the similar common bulb of sealing of the present utility model, different is to control area of flame, prevents the fire damage of LED chip in glass bulb, also can adopt the method for gas-filled protective.During exhaust; on air exhauster, carry out; in the process vacuumizing; will use argon cleaning, oven temperature is controlled at 130～160 ℃, is filled with helium (accounting for approximately 99.2%) after vacuumizing; the mist (Penning effect gas) of argon (accounting for approximately 0.8%); approximately 1 atmospheric pressure of its aeration quantity, if be the LED chip of built-in anti-pressure protection in inflation bubble, can fill He-Ne gaseous mixture (ratio of helium is greater than 87%).The certified products that exhaust completes after leakage detection are plucked bubble with flame.
Stem stem is the bracing frame of LED, core column horn mouth and the supporting sealing of glass bulb mouth are vacuum suctions, inflate, pluck the most important part of envelope, and the manufacture of stem stem is still by the manufacturing process of traditional stem stem, electrode outlet line (seal wire) can be 2～4, and the seal wire sealing with glass must be Dumet wire.Feature is that the 3rd or the 4th electrode is auxiliary glow discharge electrode, and it can play aura leakage detection and electric-field compulsion convection heat transfer' heat-transfer by convection, is conducive to protection and the heat radiation of LED chip.Interpole generally adopts the plain conductor that work function is lower, and available iron wire is zinc-plated.
