LED industrial illuminating lamp with adjustable light distributing angle

The invention discloses an LED industrial illuminating lamp with an adjustable light distributing angle. The LED industrial illuminating lamp is characterized by comprising a heat dissipation shell; end covers are installed on the two sides of the heat dissipation shell, and a cover plate is arranged on the back face of the heat dissipation shell; installing supports are fixed to the end covers; a power source cavity capable of containing a power source is formed in the back face of the heat dissipation shell, and masks are arranged on the front face of the heat dissipation shell; the power source cavity is installed on the cover plate to be fixed to the back face of the heat dissipation shell; and movable light shielding plates are arranged on the two sides of the heat dissipation shell, and scale positions corresponding to the adjusting ranges of the light shielding plates are further arranged on the opposite angle faces of the end covers. The scale positions are adjusted through the adjustable light shielding plates in a matched manner, and the light distribution angle and the glare degree of the LED mining lamp can be very conveniently adjusted; and the power source cavity is installed on the cover plate to be fixed to the back face of the heat dissipation shell, and is effectively prevented from being in direct contact with a heat source of the LED lamp, the work temperature of the power source is greatly reduced, and the whole service life of the lamp is more effectively prolonged accordingly.
