A kind of LED arc lamp module, comprise cover, glass lamp shade, LED lamp panel, radiator, radiator is arc-shaped, radiator comprises heat sink base plate and radiating fin, radiating bottom plate is arc-shaped, base plate of radiator two ends are respectively arranged with the groove that is connected, radiating fin is the linear upper surface being distributed in base plate of radiator with fan pattern of eddy-currents, each radiating fin top is that herringbone spiral gradually opens scarf, asymmetric distribution straggly between each radiating fin, wind guide tank is formed between adjacent heat radiation fin, wind guide tank one end is airtight, ventilation by forced draft mouth is provided with below the sealed end of wind guide tank.This LED arc lamp module radiating fin is that eddy-currents is linear evenly distributed along the upper surface of base plate of radiator, adopt the design of bionics vortex streamline wind-guiding, wind guide tank one end is airtight, air in wind guide tank is formed around circulation, convected air is guided to run through overall fin, improving radiating effect, and each radiating fin top is herringbone spiral gradually opens scarf, asymmetric distribution straggly between each radiating fin, the air that different directions flows so just can be utilized to enter wind guide tank, even if the flowing gas in vertical wind guide tank direction also can be stopped by the radiating fin of asymmetric distribution straggly enter wind guide tank, the intercepting principle of vertical wind guide tank direction air-flow is back and forth identical, effective intercepting moving air takes away the heat of radiating fin, ventilation by forced draft mouth is provided with below the sealed end of wind guide tank, the flowing gas enabling radiator intercept vertical radiator direction like this takes away radiating fin heat, the radiator of this LED arc lamp module can utilize the air flow of all directions to dispel the heat, radiating effect is fabulous, and this LED arc lamp module designs for arc-shaped structure, the light fixture of convenient each shape of design composition, various shapes, can more reasonably utilize each installing space, applied widely.
As preferably, the end face at described radiator two ends and the side of both sides, front and back are cambered surface.By globoidal structure, be convenient to the light fixture freely forming various pattern of LED lamp module.
As preferably, the upper surface of described base plate of radiator is cambered surface.Be cambered surface by the upper surface of base plate of radiator, facilitate the air-flow of above-below direction to stream dynamic along cambered surface in wind guide tank inner ring, fully contact radiating fin, take away radiating fin heat.
As preferably, the peak position of described each radiating fin is on a spiral involute.The air-flow that the design of this structure the most effectively can intercept all directions enters air slot.
As preferably, the inner side scarf that each radiating fin in scarf gradually opened by described herringbone spiral is that right-hand screw is gradually opened, and the outside scarf of each radiating fin is that left-hand screw is gradually opened.
As preferably, in the groove that is connected at described radiator two ends, be provided with connection positioning screw hole.
