Zusammenfassung: | To provide a semiconductor light emitting bulb which enables adjustment of a rotation angle of a valve body of the semiconductor light emitting bulb to be easily performed without removing a base from a reflector, and to provide a lighting device.SOLUTION: An LED bulb 1' is provided with a reflector 2 which is a paraboloidal body and a lens 3. A base 11 of the LED bulb 1' fits in a socket 2a and a stopper cover 2b of the reflector 2 to be fixed. The LED bulb 1' has the base 11 and a bulb body 12 fixed to the base 11 at a predetermined rotation angle. The bulb body 12 comprises an LED element attachment part 121, a base attachment part 122, a base 123, a cylindrical compression coil spring 124, and a stopper ring 125. The cylindrical compression coil spring 124 is fitted in a space between a rear contact surface of the stopper ring 125 and a front contact surface of the base 11 in a compression state.SELECTED DRAWING: Figure 1
【課題】半導体発光バルブのバルブ本体の回転角度の調整をリフレクタから口金を取外すことなく容易にできる半導体発光バルブ及び照明装置を提供する。【解決手段】LEDバルブ1'、放物面体のリフレクタ2及びレンズ3が設けられている。LEDバルブ1'の口金11がリフレクタ2のソケット2a及びストッパ付カバー2b内に嵌め込められて固定される。LEDバルブ1'は、口金11及び口金11に所定回転角度で固定されるバルブ本体12を有する。バルブ本体12は、LED素子取付部121、口金取付部122、ベース123、円筒型圧縮コイルばね124及びストッパリング125によって構成される。円筒型圧縮コイルばね124はストッパリング125の後方側の当接面と口金11の前方側の当接面との間に圧縮状態で嵌め込まれる。【選択図】図1 |
