Abstract
A lamp includes a bracket having a cover, a lamp body fixed to the bracket by a shaft, a heating device and a pressure switch. The lamp body includes first and second portions at opposite sides of the shaft. The heating device is mounted at the first portion of the lamp body and the cover. The pressure switch is mounted to the cover and engages with a top of the second portion. When a weight of the snow/ice accumulated on the first portion of the lamp body is beyond a set value, the pressure switch controls the heating device to be switched on to melt the snow/ice; when the weight of the snow/ice accumulated on the lamp body decreases to be less than the set value, the pressure switch controls the heating device to be switched off.
