The present invention relates to a lamp device, and more particularly, to a lamp device having a function of an emergency lamp, in which a lamp is configured to emit light by charging power charged in a battery when power is shut down, such that the lamp is usable as the emergency lamp, and accordingly, an additional work for constructing a separate emergency lamp is unnecessary, thereby reducing costs, time and effort for constructing the emergency lamp. The lamp device having the function of the emergency lamp according to the present invention includes: lamp function equipment; and emergency lamp function equipment, the lamp function equipment including a power unit for supplying commercial power, a first conversion unit for converting and outputting AC power supplied from the power unit into DC power, a first switching unit for being switched to pass the DC power outputted from the first conversion unit when a first enabling signal is applied, and a lamp unit for emitting light by the DC power supplied after passing through the first switching unit; and the emergency lamp function equipment, in which the first enabling signal is applied to the first switching unit when the commercial power is normally supplied by the power unit, and the first switching unit is turned off and the lamp unit spontaneously emits the light as the emergency lamp through the battery when the power shut down occurs at the power unit. |
