Description
Technical field
The utility model relates to technical field of lamps, refers in particular to a kind of LED lamp that reduces windage.
Background technology
In the very strong particular surroundings of some wind-force, can receive the influence of very strong wind-force such as the Tunnel Lamp of using on the high ferro.At present a lot of light fixtures mostly are that what to adopt is that the power that strengthens fixed mount is kept out wind-force, rather than go to reduce windage from light fixture profile flowing water type structural design.Will marry again the defective of light fixture very strong continuous being delivered on the light fixture institute installed platform device of insisting on for no reason on the supporting construction like this, make whole force structure receive windage and be easy to generate new hidden danger.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point of the prior art and a kind of light fixture profile flowing water type structural design that reduces windage is provided, and has taken into account light fixture light efficiency and heat radiation, guarantees the LED lamp of energy-saving and environmental protection, practicality simultaneously.
For achieving the above object; This novel technical scheme is: a kind of LED lamp that reduces windage; Include diffuser, aluminium base base plate, sealing ring, LED, lens fixed support, lens and be used to be connected the screw of diffuser and aluminium base base plate with several; LED, lens fixed support, lens are located on the aluminium base base plate, and the sealing ring that is used to seal is folded between diffuser and the aluminium base base plate, and said diffuser is one-body molded by plane arcuate perimeter and middle part arc convex closure around being distributed in; Wherein, the plane arcuate perimeter is formed by the orthodrome limit of an end and the roundlet arc limit smooth connection of the other end; Middle part arc convex closure seamlessly transits to another higher-end than low side by one and forms; And the roundlet arc limit of plane arcuate perimeter is corresponding than low side with middle part arc convex closure, and the orthodrome limit of plane arcuate perimeter is corresponding with the higher-end of middle part arc convex closure.
Several LED, several lens fixed supports, several lens are installed on the said aluminium base base plate.
Said diffuser is one-body molded by the perspex material.
Said diffuser is one-body molded by transparent glass material.
The shape of said aluminium base base plate is corresponding with the flat shape of diffuser.
Said LED lamp is the Tunnel Lamp of using on the railway.
Said several LED are the led light source of different capacity and colour temperature or equal-wattage and colour temperature.
Said several lens fixed supports are the support that different size structure or same size structure are used for fixing lens.
Said several lens are installed so that light more effectively projects on the unit are that needs the zone more equably by different angles size or equal angular size.
After adopting said structure; This novel diffuser and aluminium base base plate is connected firmly through screw; The diffuser of employing profile flowing water type structural design reduces the resistance of wind greatly, and wherein, the roundlet arc limit of left and right sides wind-force arcuate perimeter in face of the plane is blown over to the orthodrome limit; Blowing over to other higher-end of wind-force arc convex closure up and down than low side in face of the middle part, thus drop to the resistance of wind minimum.In addition, the diffuser that adopts transparent material to do can guarantee light efficiency, and the shape of aluminium base base plate and diffuser shape are at once; Help the bottom heat radiation; By on can know that this novel effective reduction windage has also been taken into account light fixture light efficiency and heat radiation, guarantees energy-saving and environmental protection, practical characteristics simultaneously.

The specific embodiment
Shown in Fig. 1-5 figure; A kind of LED lamp that reduces windage; Include diffuser 10, aluminium base base plate 20, sealing ring 30, LED40, lens fixed support 50, lens 60 and be used to be connected the screw 70 of diffuser 10 and aluminium base base plate 20 with several; LED40, lens fixed support 50, lens 60 are located on the aluminium base base plate 20, and the sealing ring 30 that is used to seal is folded between diffuser 10 and the aluminium base base plate 20, and said diffuser 10 is one-body molded by plane arcuate perimeter and middle part arc convex closure around being distributed in; Wherein, the plane arcuate perimeter is formed by the orthodrome limit 12 of an end and roundlet arc limit 11 smooth connections of the other end; Middle part arc convex closure seamlessly transits to another higher-end 14 than low side 13 by one and forms; And the roundlet arc limit 11 of plane arcuate perimeter is corresponding than low side 13 with middle part arc convex closure, and the orthodrome limit 12 of plane arcuate perimeter is corresponding with the higher-end 14 of middle part arc convex closure.
Several LED40, several lens fixed supports 50, several lens 60 are installed on the said aluminium base base plate 20.
Said diffuser 10 is one-body molded by the perspex material.
Said diffuser 10 also can be one-body molded by transparent glass material.
The flat shape of the shape of said aluminium base base plate 20 and diffuser 10 is corresponding.
