The invention relates to safe-type outdoor illuminating equipment with a good illuminating effect. The safe-type outdoor illuminating equipment comprises a lamp post, a cross beam, a connecting block,a lampshade and a mosquito-dispelling mechanism. The lampshade is internally provided with a dehumidifying mechanism and a cavity; the mosquito-dispelling mechanism comprises a moving unit and an airspraying unit; the moving unit comprises a driving
assembly, a sliding groove, a sliding block and a connecting rod; the air spraying unit comprises an air exhauster, a communicating
pipe, a sprayinghead, a moving block and two lifting assemblies; and the dehumidifying mechanism comprises an extending-retracting unit, a compression box, a moving plate, an air inlet
pipe, a heat exchange box, a radiating
pipe, an
air blower, a filter net and a drainage pipe. According to the safe-type outdoor illuminating equipment with the good illuminating effect, mosquitoes can be dispelled effectively through the mosquito-dispelling mechanism, the situation that light rays are shielded by the mosquitoes is avoided, and thus the illuminating effect of the outdoor illuminating equipment is strengthened;and besides, the outdoor illuminating equipment can remove
water vapor in the outdoor illuminating equipment timely through the dehumidifying mechanism, the situation that the high-temperature watervapor in the equipment damages a lamp inside the equipment is avoided, and the
service time of the outdoor illuminating equipment is prolonged.
