るという問題があった。However, the thermal conductivity of mullite, which is the material of the adhesive used in such a conventional halogen bulb with a reflector, is 2.1 W / m · k, and the insulating part of the base is The thermal conductivity of zircon cordierite of the above material is 1.
7 W / m ・ k, which is the thermal conductivity of quartz of 1.8 W / m ・ k (400
℃), which is about the same as 1.1 W / m · k of borosilicate glass for the reflector, but 102 to 109 W / m · k of tungsten, which is the material of the filament, and the metal foil inside the sealing part of the halogen bulb. 67-108 W / m of molybdenum, which is the material of
k, 59 W / m · k of nickel, which is the material used for the conductive part of the base and socket, 100 W / m · k of brass, 385 W / m · k of copper, which is the power supply wire, and aluminum, which is the material of the equipment 142W / m ・ k, which is lower than 42-63W / m ・ k of iron,
Poor heat transfer / heat dissipation through the adhesive in the halogen bulb mounting hole, the adhesive in the reflector mounting hole, or the insulating part of the base,
As a result, the temperature of the sealing portion of the halogen bulb is likely to rise. Moreover, in recent years, appliances have become smaller, which tends to raise the ambient temperature of the halogen bulb with a reflecting mirror higher than ever before. Therefore, there is a problem that the sealing portion of the halogen bulb is easily damaged. Here, if the temperature of the sealing portion is not increased, there is a problem that the degree of freedom for designing a device having a design suitable for the surrounding environment is limited.

度上昇を抑制することができる。[Function] Aluminum nitride has a thermal conductivity of 150 W / m · k, and the adhesive of aluminum nitride and the insulating part of the die are much higher in thermal conductivity than the adhesive of mullite and the insulating part of the die of zircon cordierite. Since the heat of the sealing part of the incandescent lamp is well transferred to the incandescent lamp mounting hole of the reflector through the adhesive, the heat from the adhesive surface on the upper opening side of the incandescent lamp mounting hole is also released. Good. Further, the heat of the incandescent bulb mounting hole of the reflecting mirror is satisfactorily transferred to the insulating portion of the base through the adhesive. Then, the heat transmitted to the base is dissipated to the outside from the socket or the like, and as a result, the temperature rise of the sealing portion of the incandescent light bulb can be suppressed.
