The LED lamp and the radiator thereof have the advantages of light weight and capabilities of saving materials, converting electric energy into luminous energy to the greatest extent and improving the radiating efficiency.

Description

Technical field [0001] The present invention relates to the technical field of lighting, in particular to an LED lamp radiator and an LED lamp. Background technique [0002] At present, the radiator structure of the LED lamp module mostly adopts the strip module, which is beneficial to the splicing and assembly of several modules to form the whole lamp structure of the floodlight or street lamp, but the strip module still has the following disadvantages: Floodlights and street lights can only be formed by combination and arrangement, but for industrial lighting fixtures, it is not easy to combine. Because the shape and structure of industrial lighting fixtures are fundamentally different from strip modules, and the spot shape formed by industrial lighting cannot be formed, especially for application environments that require high uniformity of illuminance. The installation height of industrial lighting fixtures is generally 3-5 meters. If long strip modular lamps are used, the l...

AI Technical Summary

Problems solved by technology

[0002] At present, the heat sink structure of LED lighting modules mostly adopts strip modules, which is conducive to the splicing and assembly of several modules to form a whole light structure of floodlights or street lights, but strip modules still have the following disadvantages: Floodlights and street lights can only be formed by combining and arranging, but it is not easy to combine for industrial lighting fixtures

Because the shape and structure of industrial lighting fixtures are essentially different from those of strip modules, and they cannot form the spot shape of industrial lighting, especially for application environments that require high uniformity of illumination.

The installation height of industrial lighting fixtures is generally at a height of 3-5 meters. If a long strip module lamp is used, at this installation height, the light spots projected on the workbench will cause glare, ghosting and other factors, which will affect the visual effect.

[0003] Circular radiators can solve the above-mentioned problems of strip modules, but circular radiators are mostly used for spherical lamps, PAR lamps, spotlights, etc. below 10W. Because these LED lamps have low power, they are not effective for heat dissipation. The requirements are not high, and the circular die-casting heat sink with conventional structure can meet the heat dissipation requirements.

The structure of this kind of circular radiator is mostly arranged symmetrically along the circumference, the height of the radiator is not high, and the heat dissipation area of ​​the whole lamp is not large

[0004] However, the existing circular heat sink has low heat dissipation efficiency and cannot meet the heat dissipation requirements of high-power LED lamps.
