PROBLEM TO BE SOLVED: To allow a construction lamp which is installed in a construction site and the like and which draws attention by blinking and emitting light to operate with a dry battery as a power source in the case where the amount of charge of a charging part is small by automatically switching the power source, even when the construction lamp, as a rule, operates with the combination of a solar cell and the charging part as the power source.SOLUTION: A construction lamp includes: a solar cell 23; a charging part 25 for storing power photoelectrically converted by the solar cell 23; a dry battery storage part for storing a dry battery 11; and a power source switching part 27 for supplying power to a portion which needs power out of the construction lamp 1 from the charging part 25 when a voltage of the charging part 25 is equal to or greater than a predetermined value, and for supplying power to a portion which needs power out of the construction lamp 1 from the dry battery 11 when the voltage of the charging part 25 is lower than the predetermined value.SELECTED DRAWING: Figure 9
【課題】工事現場等に設置され、点滅発光して注意を喚起する工事灯において、原則としては太陽電池と充電部との組み合わせを電源として動作するが、充電部の充電量が少ない場合には、自動的に電源を切換え、乾電池を電源として動作するようにする。【解決手段】太陽電池２３と、この太陽電池２３によって光電変換された電力を蓄える充電部２５と、乾電池１１を収容する乾電池収容部と、充電部２５の電圧が所定値以上のときは充電部２５から当該工事灯１のうちの電力を必要とする部分に電力を供給させる一方、充電部２５の電圧が所定値より低いときは、乾電池１１から当該工事灯１のうちの電力を必要とする部分に電力を供給させる電源切換部２７とを設ける。【選択図】図９
