Abstract
The utility model relates to an emergency illuminating lamp including a power supply circuit converting AC electric supply into a DC power supply, a control circuit, a power storage device and an illuminating device. The power storage device is a super capacitor. The illuminating device is a group of light-emitting diodes. In the utility model, the super capacitor is adopted to supply power to the illuminating device directly, thereby reducing environmental pollutions in a producing, using and discarding process of a storage battery. Besides, the super capacitor has no self discharge. Thus, the power of secondary charge is reduced substantially and the energy is saved. At the same time, the weight of the emergency lamp is reduced and the service lifetime of the emergency lamp is prolonged. The illuminating device is a multi-point illuminating device having high lighting effect, long service lifetime and low working temperature. Thus, not only the electric energy is saved, but also the whole illuminating device failure caused by the damage of an individual light-emitting diode is avoided, thereby improving the reliability of the illuminating device. The emergency illuminating lamp in the utility model has a low weight and is convenient to carry. And the emergency illuminating lamp in the utility model can be applied to any occasion that needs emergency illumination.
