Abstract
A single-ended discharge lamp has a discharge tube comprising at least two tube legs and a housing for mechanical and electrical connection to a lampholder. The housing comprises a tube supporting part, a housing part and a lamp cap. Holes are provided in the tube supporting part through which the legs of the discharge tube extend. The ends of the legs of the discharge tube inside the supporting part are fixed thereto with a bonding material. The bonding material is applied to the radially outer portion of the tube supporting part.
Description
The present invention relates to a kind of single-end discharge lamp, it has a discharge tube that comprises two pipe legs at least, and one is designed to carry out machinery and the cap body that is electrically connected with lamp socket.The cap body is made up of a pipe support, a connector and a lamp holder, and these several parts are connected together.Be shaped on hole on the pipe support, the discharge tube leg places hole, and the bonded material in end of the discharge tube leg in the cap body is fixed, and binding material is coated in around the perimeter of the pipe support of discharge tube.
Above-mentioned single-end discharge lamp-mainly be that compact fluorescent lamp is in commercial sale.It has one to comprise four or the discharge tube of six roots of sensation glass tube leg.The end of the discharge tube leg in the cap body is used round the thermosetting adhesive of discharge tube and is fixed on the pipe support.Binder material serves as the outside gauge with the outer rim of pipe support usually.When making, behind the coated with adhesive material, binder material is through heating and solidifying behind the maintenance certain hour under the given temperature.During this period, binding material expands and solidifies, because the adhesive effect from the pipe support outer rim to the glass tube leg, thereby the pipe leg is remained fixed in the pipe support.
The problem that these discharge lamps often occur is that the pipe leg oneself disconnects or breaks sometimes.Rule of thumb, this natural disconnection or break and can not only take place on the make, and after occurring in making, for example install, transport or face under the situation that mechanical load increases at discharge lamp.So just damaged the reliability of discharge lamp.
The purpose of this invention is to provide the solution that to eliminate the above-mentioned defective of discharge lamp, thereby make the reliability of discharge lamp obtain increasing.
The theory that the present invention is based on is that because the expansion and the curing of binding material, mechanical force is applied on glass, thereby has further increased the stress that glass produced in the making in earlier stage.By stress being reduced with a kind of binding material.At this moment binding material not only will be coated in round the perimeter of the pipe support of discharge tube, and is coated in the zone by discharge tube the inside of pipe leg gauge.
According to top described, involved in the present invention single-end discharge lamp a discharge tube that comprises two pipe legs is at least arranged, and one is designed to carry out machinery and the cap body that is electrically connected with lamp socket.The cap body is made up of a pipe support, a connector and a lamp holder, and these several parts are connected together.Be shaped on hole on the pipe support, the discharge tube leg places hole, the end of the discharge tube leg in the cap body is centered on the coated binding material in perimeter of the pipe support of discharge tube and is fixed, and the binding material that the end of the discharge tube leg in the cap body also is applied to by the zone, discharge tube the inside of pipe leg gauge is fixed on the pipe support.
In a preferred embodiment of the invention, on pipe support, in the interior zone between the hole on the pipe support, there is one to stretch to cap body the inside, and supports the ribs of binding material.Therefore, the ribs and the outer rim of the pipe support of appropriate size arranged, the space or the surface that are suitable for accepting and supporting binding material can be provided, and guarantee to be absorbed by the stress that expansion and curing produced of binding material.
In order to offset the stress that applies by binding material more equably, especially effectively more in the pipe leg quantity of discharge lamp, be under the situation of the six roots of sensation at least, the ribs of use be shaped as cylindrical sleeve.
Use method of the present invention, the glass tube leg is not subjected to uneven pressure, thereby they will bear less mechanical stress.In addition, the present invention be advantageous in that the bed knife between the pipe leg of the pipe support of cap body and discharge tube, that is, this bonding can be born higher mechanical load.The present invention is more in the pipe leg quantity of discharge tube, and under the six roots of sensation, eight situation, effect is more remarkable.
Below, the embodiment shown in is for a more detailed description to the present invention with reference to the accompanying drawings.
Fig. 1 is the cutaway view of the embodiment of a discharge lamp of the present invention.
Fig. 2 is the front view of an embodiment of discharge lamp of the present invention.
Discharge lamp among Fig. 1 and Fig. 2 is an OCT type compact fluorescent lamp, and it has a discharge tube 2 and a cap body 4.Discharge tube 2 has electrode (not drawing), and is filled with gas and metallic vapour, and also has eight pipe leg 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, and the external diameter of pipe leg is 12mm, and adjacent pipe leg connects together each other, forms the continuous discharge space of a closure.Cap body 4 is made up of 5, one connectors 6 of a pipe support and a lamp holder 7.On pipe support 5, be formed with circular opening, it is on the circle of 37mm that the center of circle of these openings is divided in a diameter.Opening is accepted pipe leg 3a, 3b, 3c, 3d, 3e, 3f, 3g, the 3h of discharge tube 2.In addition, a ribs 10 that stretches to cap body 4 the insides, is shaped as cylindrical sleeve is arranged on pipe support 5, its material is close with pipe support 5, and thickness is 1mm, highly is 6.5mm, and internal diameter is 20mm.As making with the terephthalate polybutene, they mesh together by plastics for pipe support 5 and connector 6, or bonding and interfix if desired the time.Lamp holder 7 is fixed on the connector 6, and lamp holder 7 has one for example to be the structure of screw thread, to be inserted in the lamp socket.The circuit of a control discharge tube 2 can be put in 6 li of connectors.Control circuit is connected with the electrode of discharge tube 2 on the one hand, is connected with lamp holder 7 on the other hand.
End at the pipe leg 3a of the discharge tube 2 of cap body 4 the insides, 3b, 3c, 3d, 3e, 3f, 3g, 3h is fixed on the pipe support 5 with binding material 9 (being represented by lattice shape hachure among the figure).Binding material 9 is used in two places, and a place is perimeter 11, this zone around discharge tube 2 and in the outside by cylindrical sleeve 8 gauges, the external diameter of cylindrical sleeve 8 is 53.5mm, wall thickness 2mm; Another place is an interior zone 12, by pipe leg 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h gauge, but does not go out the outside of ribs 10.
Binding material 9 is a kind of by thermosetting adhesive natural and artificial resin and solvent composition.After the coating, binding agent is heated to curing, or is incubated a few minutes under 100 to 180 ℃ temperature.The binding agent that is used for perimeter 11 and interior zone 12 quantitatively preferably cover row above and and figure shown in the several sections of scope, but be about except 1 to 3mm the zone at width between the adjacent tubes leg.Because binding material 9 following the shape of manage the leg end, so its continues to stretch to from both sides and manages the position of tightening of leg end.After insulation, binding material 9 reaches height 7 to 8mm with respect to the surface of pipe support 5 at interior zone, and externally the zone reaches height 8 to 9mm.
In the example of above-mentioned discharge lamp, average energy bears the 5Nm torsional moment and can not damage between pipe support 5 and the discharge tube 2, and an onesize OCT discharge lamp only is used at binding material 9 under the situation of perimeter 11, and the numerical value that bears torsional moment is about 2.5Nm.
Discharge lamp of the present invention according to protection range, can constitute with several method, and therefore, the present invention is not confined in any characteristics of mentioning of above-mentioned example.
