　また、ランプ本体８２の支持面８２ａには、一対の押圧部材９１，９２が、ねじ９３により取り付けられている。各押圧部材９１，９２の各々は、ステンレス鋼板を階段状に折り曲げた板ばねにより構成されている。また、各押圧部材９１，９２の各々は、固定部９１ａ，９２ａ、起立部９１ｂ，９２ｂおよび押圧部９１ｃ，９２ｃを有している（図１１参照）。 In addition, a pair of pressing members 91 and 92 are attached to the support surface 82 a of the lamp body 82 by screws 93. Each of the pressing members 91 and 92 is configured by a leaf spring obtained by bending a stainless steel plate in a step shape. Each of the pressing members 91 and 92 has a fixing portion 91a and 92a, an upright portion 91b and 92b, and a pressing portion 91c and 92c (see FIG. 11).

　ところで、図１０に示した構成のＬＥＤランプ８１では、各押圧部材９１，９２の押圧部９１ｃ，９２ｃの各々が、ランプ本体８２の支持面８２ａに向かって発光装置８６を弾性的に押圧するので、発光装置８６の基板８８がランプ本体８２と熱的に接続される。 Incidentally, in the LED lamp 81 having the configuration shown in FIG. 10, each of the pressing portions 91 c and 92 c of the pressing members 91 and 92 elastically presses the light emitting device 86 toward the support surface 82 a of the lamp body 82. The substrate 88 of the light emitting device 86 is thermally connected to the lamp body 82.
　これにより、上述のＬＥＤランプ８１では、発光ダイオードチップ８９の発光時に、発光ダイオードチップ８９で発生した熱を、ランプ本体８２の各放熱フィン８７からＬＥＤランプ８１の外部へ放熱することが可能となり、発光ダイオードチップ８９の温度上昇を抑制することが可能となる。 Thereby, in the above-mentioned LED lamp 81, when the light emitting diode chip 89 emits light, the heat generated in the light emitting diode chip 89 can be dissipated from the heat radiation fins 87 of the lamp body 82 to the outside of the LED lamp 81. It becomes possible to suppress the temperature rise of the light emitting diode chip 89.
　しかしながら、図１０に示した構成のＬＥＤランプ８１では、ステンレス鋼板の板ばねにより構成された各押圧部材９１，９２の各々が、ねじ９３を用いて金属製のランプ本体８２に取り付けられている。 However, in the LED lamp 81 having the configuration shown in FIG. 10, each of the pressing members 91 and 92 formed of a stainless steel plate spring is attached to a metal lamp body 82 using screws 93.
　そのため、このＬＥＤランプ８１では、基板８８の充電部（上記配線パターン）の絶縁性能を高めようとすると、各押圧部９１ｃ，９２ｃと、封止材９０により覆われた上記配線パターンおよび各発光ダイオードチップ８９との間の沿面距離が長くなり、基板８８の平面サイズが大きくなるという懸念がある。 Therefore, in this LED lamp 81, in order to improve the insulation performance of the charging portion (the wiring pattern) of the substrate 88, the wiring patterns and the light emitting diodes covered with the pressing portions 91c and 92c and the sealing material 90 are used. There is a concern that the creepage distance to the chip 89 is increased, and the planar size of the substrate 88 is increased.
