[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: an adjustable-angle industrial and mining lamp, including a heat-dissipating mining lamp housing 4, an aluminum substrate 5, LED lamp beads 6, and a lens 12. The aluminum substrate 5 is arranged inside the heat-dissipating mining lamp housing 4. The LED lamp beads 6 are arranged in an Archimedean spiral shape with a starting angle of 90° at the bottom of the aluminum substrate 5. The lens 12 is arranged at the inner bottom of the heat-dissipating mining lamp housing 4 and covers the aluminum substrate 5 therein. The aluminum substrate 5 and the lens 12 are parallelly distributed. Three Archimedean spiral optical surfaces with starting angles of 60°, 90°, and 120° are integrally formed on the lens 12 and are sequentially surrounded by each other from the inside to the outside. The convex surfaces of the three optical surfaces on the lens 12 face downward. The optical surface with a starting angle of 90° on the lens 12 is perpendicularly distributed and correspondingly arranged with the LED lamp beads 6. The position of the lens 12 can be rotated and adjusted according to the use requirements. By means of the fixed irradiation angles of the three optical surfaces on the lens 12 and the LED lamp beads 6, the angle of the light irradiated through the lens 12 is changed, so as to achieve the effects of spotlight and floodlight, reduce the occurrence of glare in different use scenarios, and improve the actual use experience. An angle pointing arrow 17 is arranged at the outer ring position of the bottom of the power supply 3. Angle markings 16 with three groups of corresponding angle values are arranged at the outer ring position of the bottom of the angle marking 16 according to the starting angles of the three optical surfaces on the power supply 3. During operation, only the locking lens screw 13 needs to be removed, and the lens 12 is rotated 120 degrees to quickly switch to another optical angle, and the operation is convenient and fast.

[0020] Among them, a suspension ring 1, a power supply locking screw 2, and a power supply 3 are sequentially arranged from top to bottom above the heat-dissipating miner's lamp housing 4. The power supply 3 is installed on the top of the heat-dissipating miner's lamp housing 4 through the power supply locking screw 2. The suspension ring 1 is detachably installed on the top of the power supply 3. A locking aluminum substrate screw 7 is arranged below the aluminum substrate 5. The aluminum substrate 5 is fixedly connected to the inner top of the heat-dissipating miner's lamp housing 4 through the locking aluminum substrate screw 7 and is in close contact with the heat-dissipating miner's lamp housing 4. A waterproof ring 8 is arranged between the heat-dissipating miner's lamp housing 4 and the lens 12. A locking lens screw 13 is arranged below the lens 12. The lens 12 is connected to the bottom of the heat-dissipating miner's lamp housing 4 through the locking lens screw 13.

The locking PCB screw 10 is connected to the inductor 15 through the PCB terminal 9. Below the lens 12, there is a lens plug screw 14, and the lens plug screw 14 is connected to the center position of the lens 12.

[0021] Working principle: When the optical angle needs to be adjusted, remove the locking lens screw 13, and rotate the lens 12 to the corresponding angle according to the indication of the angle mark 16 and the angle pointing arrow 17. The illumination light of the LED lamp bead 6 during rotation passes through different optical surfaces on the lens 12. When the LED lamp bead 6 is aligned with the 60° optical surface on the lens 12, the light of the LED lamp bead 6 converges inward to achieve a spotlight effect. When the LED lamp bead 6 is aligned with the 120° optical surface on the lens 12, the light of the LED lamp bead 6 diverges outward to achieve a floodlight effect.
