Abstract

The utility model discloses a novel LED lamp, which is provided with a mounting bracket, a cooler and an LED lamp; the LED lamp is provided with a shell, a radiator, a power supply, an LED light-emitting module and a lens; the interior of the radiator is provided with a cavity for containing cooling liquid, the right end of the cavity is provided with a liquid outlet, and the left end of the cavity is provided with a liquid inlet; the cooler is provided with a step motor, a controller, a temperature probe and a pump head, the step motor is connected with the mounting bracket, and the pump head is mounted on the output shaft of the step motor; a water inlet of the pump head is connected with the liquid outlet of the cavity through a duct; and a water outlet of the pump head is connected with the liquid inlet of the cavity through a duct. The novel LED lamp utilizes the cooling liquid in the radiator to enhance heat dispersion; when heat cannot be dissipated in time due to the change of the external environment, the pump head can be driven by the step motor to rotate, so that heat can be more rapidly dissipated; and meanwhile, the novel LED lamp has the advantages of adjustable light-emitting angle, lower light attenuation, higher luminous efficiency and longer service life.

Description
