の一因となつていた。 Conventionally, inorganic adhesives have been used to bond the bulb body and accessories such as protective insulators and concave reflectors, and this adhesive has been used between the attachment hole of the attachment and the pinch seal part of the bulb body. was used to secure the bulb body and attachment. By the way, the halogen light bulb becomes extremely hot when lit, and the pinch seal, attachment part, and adhesive layer expand with their respective expansion coefficients, but the amount of expansion is significant in the long side direction of the pinch seal. It is. Therefore, when the thermal cycle caused by turning on and off the halogen bulb body is applied to these fixed parts, compressive and tensile forces are applied to the pinch seal part and the adhesive layer, especially in the longitudinal direction of the pinch seal part, due to the slight difference in the amount of expansion between the three parts. It will be added repeatedly in the direction. Further, the lead rod led out from the pinch seal portion may be bent during the manufacturing process, and this bending must be corrected. However, since the conventional adhesive layer was a dense layer over the entire circumference of the pinch seal, there was no place for the compressive force or tensile force due to the difference in expansion and contraction mentioned above, or the force applied to straighten the lead rod, to escape. 100% of the force, tensile force, or straightening force is applied to the aforementioned pinch seal portion and adhesive layer, contributing to defects in the attachment portion such as chipping of the pinch seal portion, seal leakage, and cracks in the adhesive layer.

FIG. 1 shows an example in which a halogen light bulb 1 is attached to a concave reflector 3a. It is protruding from the center of the back. The mounting portion 9 is provided with a mounting hole 4 having a substantially rectangular cross section and opening into the concave mirror portion 12 . The inner surface of the concave mirror portion 12 may be simply flat and spherical, but it may be formed with a number of cut surfaces or dimples to match the filament 10 of the halogen bulb 1.
It may be formed so that the light reflected by is parallel or condensed at one point. In the case of FIG. 1, a pinch seal part 2 having a substantially rectangular cross section is formed at the lower end of the halogen bulb body 1, and a filament 10 is installed between internal lead rods that stand up from this pinch seal part 2. . Then, the pinch seal part 2 of the light bulb body 1 is inserted into the mounting hole 4, and an inorganic adhesive is poured between the mounting hole 4 and the short side 5 of the pinch seal part 2 and heated to about 250°C. Then, the moisture in the adhesive turns into water vapor and escapes, leaving behind a foamed layer (foamed layer 6), which dries in a short time while remaining foamed. Next, adhesive is filled between the long side 7 of the pinch seal part 2 and the mounting hole 4, and the adhesive is heated to 100°C.
The front and back portions are slowly hardened to form a dense layer 8. This diagram is shown in FIG. In this example, the first
As shown in the figure, the case where the concave reflector 3a and the halogen bulb body 1 are bonded is shown, but of course the case is not limited to this, and the straight tube type halogen bulb body 1 having pinch seal portions 2 at both ends and its pinch seal portion 2 are shown. This can also be applied to the case of a protective insulator that is fitted into the halogen lamp body 1, and the attachment 3 refers to the concave reflector 3a, the protective insulator, etc. that are fixed to the halogen bulb body 1.

に外観ををさほど損なわないものである。 As described above, the present invention involves inserting the pinch seal formed at the lower end of the light bulb into the attachment hole of the accessory.
Since the adhesive layer filled between the short side of the pinch seal part and the mounting hole is a foam layer, the heat cycle caused by turning on and off the light bulb is not applied to the pinch seal part, the adhesive layer, and the attachment part of the accessory. , will be expanded and contracted repeatedly with each expansion coefficient,
(This tendency is particularly noticeable in the longitudinal direction of the pinch seal part.) The foamed adhesive layer absorbs this difference in expansion and contraction, causing seal leaks in the pinch seal part, cracks in the adhesive layer, etc. This is to prevent malfunctions. In addition, the foam layer relieves the correction force when correcting the bending of the lead rod.
This prevents 100% correction force from acting on the pinch seal portion and prevents the pinch seal portion from chipping. Furthermore, this foam layer solidifies quickly because it is heated and dried, and since the adhesive part is only a part, it has a temporary fixing effect between the pinch seal part and the mounting hole.
There is no need to hold the pinch seal portion and the bulb body until the adhesive hardens as in the conventional method, which has the advantage of shortening the working time. Furthermore, since the adhesive layer filled between the long side of the pinch seal part and the mounting hole is a dense layer, it can exhibit the original adhesive strength of the adhesive, improving the adhesive strength and appearance between the accessory and the bulb body. It does not impair it much.
