The following describes breakage of suppressing generation by thermal distortion during heating.
(A) when fused to the case glove 35 and the lid member 37 there is no restriction member, to heat the abutting periphery of both a burner or the like. In this case the heat is transferred to the glove 35 and the lid member 37.

Glove 35 side of the heat spreading to the contact portion (heating portion) and as a starting point the top side of the globe 35 (an opening opposite.), Is released into the surrounding air.

On the other hand, the heat of the lid member 37 side, starting from the contact portion (heating portion), and is released as radiant heat while being discharged into the surrounding air spreading into the center of the lid member 37. The lid member 37, since the metallic support member 9 for supporting the LED module 11 is provided, the heat of the lid member 37 is conducted to better support member 9 side heat conductivity, the container from the support member 9 It is discharged to the periphery of the third air.

Therefore, after the heating, the temperature of the contact peripheral portion is hard down on the glove 35, the temperature of the contact periphery of the cover member 37 tends to easily fall. As a result, after the heating, the temperature difference becomes large at the touching the periphery of the glove 35 and the lid member 37, thermal distortion is large, a state in which cracks are likely to occur.
(B) upon fusion of the globe 35 and the lid member 37 when there is a suppression member, as if there were no restraining member as described above, the heat of the burner or the like is transmitted to the glove 35 and the lid member 37. Glove 35 side of the heat spreading to the contact portion (heating portion) and as a starting point the top side of the globe 35 (an opening opposite.), Suppression for (glove 35 released into the surrounding air member is the same as if there is no.).

On the other hand, the heat of the lid member 37 side, starting from the contact portion (heating portion), and is released as radiant heat while being discharged into the surrounding air spreading into the center of the lid member 37. (In other words, the position. Between the base 42 of the lid member 37 supporting body 41) position the inner surface facing the cover member 37 for suppressing member 52 to is provided, released from the lid member 37 is reflected in part by radiant heat inhibiting member 52, part of it is absorbed.

Becomes the lid member 37 is heated by radiant heat reflected by the suppressing member 52, the temperature drop of the lid member 37 is prevented. The temperature of the rod 40 which is suppressing member 52 and the restraining member 52 are attached by being absorbed by the suppressing member 52 heat rises, the temperature difference between the lid member 37 and the bar 40 is reduced, bar 40 from the lid member 37, heat transfer to the pedestal 42 is suppressed.

Therefore, after heating, there is a hardly tends to temperature fall of the contact periphery of the cover member 37, as a result, after fusion, the temperature difference in the contact periphery between the globe 35 and the lid member 37 is reduced , thermal distortion is small, a state in which cracks hardly occur.

Incidentally, in order to efficiently increase in temperature by radiation heat the suppressing member, the more the heat capacity of the suppressing member is small well, it specifically smaller than the thermal capacity of at least the support body is preferred.
