Problems solved by technology

However, the air flow speed near the radiator on the existing LED spotlights is completely dependent on the outside world, and the contact area between the radiator and the air is relatively small, so the heat dissipation effect is limited

Abstract

The invention relates to an LED lamp comprising an LED lamp body, a light gathering cover, a radiator and a pressing ring. The LED lamp body is fixedly connected to the light gathering cover, the radiator sleeves the periphery of the light gathering cover, and a clearance is formed between the radiator and the light gathering cover; the pressing ring is mounted at the top of the light gathering cover; an accommodating space used for accommodating the light gathering cover is formed inside the radiator, is the same as the light gathering cover in shape and penetrates the top of the radiator; an annular boss is arranged at the top of the radiator in a convex manner and surrounds the periphery of the pressing ring; the pressing and the annular boss are fixed in a clamped manner; a radiating clearance is formed between the outer wall of the pressing ring and the inner wall of the annular boss; the outer surface of the side wall of the radiator is provided with a plurality of first radiating fins at intervals; a plurality of radiating holes are formed in the side wall of the radiator; the inner surface of the side wall of the radiator is provided with a plurality of second radiating fins at intervals. The LED lamp has fine radiating effect and is convenient to mount.

Description

technical field [0001] The invention relates to the field of photoelectric technology, in particular to an LED spotlight. Background technique [0002] At present, when LED (Light Emitting Diode) is emitting light, only 30%-40% of the electrical energy is converted into light energy in the end, considering the current injection efficiency, radiative luminescence quantum efficiency, and external light extraction efficiency of the crystal. The remaining 60%-70% of the energy is mainly converted into heat energy in the form of lattice vibration that occurs through non-radiative recombination. [0003] The converted heat energy is concentrated in a small area, which makes the temperature of the semiconductor crystal rise, causing non-uniform distribution of thermal stress, affecting the light efficiency and service life of the LED, and solving the problem of heat management has become the application of LED spotlights. prerequisites. [0004] For existing LED spotlights, gener...
