Existing LED lamp module is usually vertical bar shaped design, the fin of radiator is also adopted by square-folded rectangle heat sink shape design, the LED lamp of the LED lamp module composition of vertical bar shaped design is usually the shape design of cuboid, body is single, moulding is inflexible, can not more reasonably utilize installing space, the place especially needing curvilinear portion to install at some car bodies etc. is the most inapplicable, and the radiator of rectangular shape and the design of fin of rule side by side, can only be single dispel the heat in one direction, corresponding the wind direction of multiple directions cannot be utilized to dispel the heat, radiating effect is poor.
Summary of the invention
For solving above-mentioned technical problem, the present invention devises and a kind of can freely form variously-shaped light fixture and the splendid LED arc lamp module of radiating effect.
The present invention adopts the following technical scheme that
A kind of LED arc lamp module, including cover, glass lamp shade, LED lamp panel, radiator, radiator is arc-shaped, radiator includes base plate of radiator and radiating fin, base plate of radiator is arc-shaped, base plate of radiator two ends are respectively arranged with combination link slot, 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 oblique section gradually opened by herringbone spiral, 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 it is provided with below the sealed end of wind guide tank.nullThis LED arc lamp module radiating fin is that eddy-currents is linear evenly distributed along the upper surface of base plate of radiator，Use the design of bionics vortex streamline wind-guiding，Wind guide tank one end is airtight，The air in wind guide tank is made to be formed around circulation，Convected air is guided to run through overall fin，Improving radiating effect，And each radiating fin top is that oblique section gradually opened by herringbone spiral，Asymmetric distribution straggly between each radiating fin，The air that thus may utilize different directions flowing enters 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 enters wind guide tank，The intercepting principle of vertical wind guide tank direction air-flow back and forth is identical，Effectively intercept moving air and take away the heat of radiating fin，Ventilation by forced draft mouth it is provided with below the sealed end of wind guide tank，The flowing gas so enabling radiator intercept vertical radiator direction 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，Convenient design forms the light fixture of each shape，Various shapes，Can more reasonably utilize each installing space，Applied widely.
As preferably, the side of the end face at described radiator two ends and front and back both sides is cambered surface.Pass through globoidal structure, it is simple 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 along cambered surface at wind guide tank internal ring around flowing, be fully contacted 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 of the design maximally effective intercepting all directions of energy of this structure enters air slot.
As preferably, the inner side oblique section of each radiating fin in oblique section gradually opened by described herringbone spiral is that right-hand screw is gradually opened, and the outside oblique section of each radiating fin is that left-hand screw is gradually opened.
As preferably, in the combination link slot at described radiator two ends, it is provided with connection positioning screw hole.
