Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a lighting device for use at low temperatures driven by a battery and capable of carrying out stable lighting even in a low-temperature environment. SOLUTION: This lighting device for use at low temperatures is structured such that the temperature of a battery is kept at a high temperature as compared with an ambient temperature by transmitting heat generated when light emitting diodes 10 being light emitting elements, an electronic component 61 and the like are being operated to the battery 20 through a heat-transfer plate 30 being a thermally-conducting member.
