Abstract
The invention brings forward an LED industrial and mineral lamp comprising a lamp head, a lamp body, a power supply component, a heat radiator, a light source piece and a light source face shield which are installed in turn. The power supply component is installed in the lamp body. The heat radiator is provided with a recessed part which is used for installing the power supply piece. The power supply component comprises the following circuit units: a power supply unit, a temperature measuring unit, a microprocessor unit and a power supply driving unit. When ambient temperature measured by the temperature measuring unit surpasses the highest temperature of the lamp body, the microprocessor unit sends a signal of a cooling requirement to the power supply driving unit which reduces output of voltage or current. The aforementioned process is repeated until the ambient temperature is ensured not to surpass the highest temperature of the lamp body. Current and voltage can be automatically reduced so that normal use of the lamp can be better protected.
