Embodiment
Fig. 1 and Fig. 2 are the figure of expression discharge lamp of the present invention.As shown in Figure 1, the inside of discharge lamp 1 pipe 4 in glass airtight, the lamp main body 2 of holding the luminous tube 3 of ceramic gold-halogen lamp etc. is installed on the lamp holder 6.Outer tube 5 is bonded on the lamp holder 6 with the mode of holding lamp main body 2.
The sealing of lamp main body 2 one ends, the other end forms crush seal portion 7.The couple of conductor 8 of luminous tube 3 exports to lamp main body outside from crush seal portion 7.The lead 8 of deriving is connected with lamp holder 6.Through supplying power from outside guiding line 8, luminous tube 3 is lighted.Lamp holder 6 is made up of installation portion 11 and cap body 12.After lamp main body 2 was installed to installation portion 11 with outer tube 5, lamp main body 2 was installed on the cap body 12 with outer tube 5, and discharge lamp 1 is accomplished.
Fig. 3 is the figure of the installation portion 11 of expression lamp holder 6.
As shown in Figure 3, installation portion 11 is made up of lamp maintaining part 13, flange 14 and lamp holder insertion section 15.Central authorities at installation portion 11 are formed with the lamp insertion mouth 17 that is used to supply 2 insertions of lamp main body and fixes.Recess 16 is formed at two relative places for the zone of the adhesive of filling the outer tube 5 that is used to bond.Recess 16 is as adhesive surface 9.In addition, recess 16 also can be formed on more than two places.For example, also the recess 16 more than 3 places can be set equally spaced around installation portion 11.
In the present embodiment, use the lamp holder of the white that forms by steatite, and be the white inorganic heat-resistant adhesive of main component with aluminium oxide and silicon dioxide.
The central authorities of lamp maintaining part 13 are formed with lamp and insert mouth 17.After lamp main body 2 is inserted and is fixed in lamp and inserts mouthfuls 17, adhesive is filled into recess 16.Insert outer tube 5 with the mode of holding lamp main body 2, on the position of the end of outer tube 5 and flange 14 butts, outer tube 5 is bonding with installation portion 11.
The radius of lamp maintaining part 13 forms slightly forr a short time than the internal diameter of outer tube 5, and their gap portion is filling adhesive not, and adhesive only is filled in the recess 16 of installation portion 11.Thereby recess 16 becomes substantial adhesive surface 9.
Adhesive surface is more little to keep good surface appearance more, but too small adhesive surface can cause adhesion strength to reduce.Therefore, for improving adhesion strength, the present inventor has carried out the trial-production test to confirm the area of optimum adhesive surface.
Fig. 4 is the result according to the area estimation adhesion strength of the external diameter of the bonding part of the outer tube of the discharge lamp of trial-production and adhesive surface.If the external diameter of outer tube is D (mm), the average area of the adhesive surface at two places is S (mm
2).Apply excessive power based on torsional moment test to discharge lamp.Among Fig. 4, the trial-production specification that can obtain sufficient adhesion strength is used zero symbolic representation, can not obtain the trial-production specification usefulness * symbolic representation of sufficient adhesion strength.
Can know that based on this test the D outer diameter of outer tube is big more, just be necessary to increase the average area S of the adhesive surface at two places more, the area of adhesive surface satisfies 2D-18≤S, can obtain sufficient adhesion strength.
In addition, the big more adhesion strength of the area of adhesive surface is high more, but also there is following problem in bond area greatly except that the infringement outward appearance.
When adhesive surface was big, the use amount of adhesive increased, thereby needed bigger energy and longer time in the drying process when bonding.Drying process in the present embodiment keeps carrying out under 30 minutes the condition in 200 ℃ body of heater.For bond area is 50mm
2Above preproduction carries out drying under this drying condition, because can not intensive drying, though bond area is bigger, adhesion strength is still low.
Change the condition of drying process, carry out drying through spending bigger energy and longer time, bond area reaches 50mm
2Above product also can obtain sufficient drying, but can cause the cost of drying process to rise.Therefore, bond area is at 50mm
2Below be appropriate.
Fig. 5 is the front view (a) and the cutaway view (b) of expression another embodiment of the present invention.
As shown in Figure 5, also can at interior side direction protuberance 10 be set at the adhesive surface of outer tube 5.Through the setting of protuberance 10, can increase the bond area that influences adhesion strength.On the other hand, do not change because apparent bond area is compared with the situation that does not have protuberance 10, thereby can keep good surface appearance.As long as the shape of protuberance can increase bond area, be not limited to the inboard projection that is arranged on shown in Figure 5.For example, protuberance also can through under heated condition from the outside application of force of outer tube 5 and to the inside depression form.
Fig. 6 is the cutaway view of expression another embodiment of the present invention.
As long as the size of protuberance 10 can increase the bond area that influences adhesion strength, and being preferably more than the 1mm apart from d between protuberance 10 shown in Figure 6 and bonding part end face.This is because apart from d, even when applying the power of the direction that outer tube 5 for example breaks away from from installation portion 11, protuberance 10 blocks the adhesive part, is difficult to break away from, thereby can improves intensity through this.And this effect is not only effective for the power that breaks away from direction, and is also effective for the power of circumferencial direction.
And, form step through lamp maintaining part 13 and flange 14 on the installation portion 11.Can damage outward appearance because adhesive spills into the top of lamp maintaining part 13, preferably adhesive surface is controlled in this scope.And because adhesive and lamp holder 6 are homochromy, adhesive is difficult for seeing with assimilating on every side, thereby can keeps good surface appearance.In addition, the color of adhesive and lamp holder 6 need not identical, and adhesive is that the isonomic color that is difficult for discovering gets final product.
As stated, according to the present invention, can be implemented in when reaching sufficient adhesion strength, the control bond area keeps good surface appearance.
