Background technology
For the fishing water surface light fixture that sea uses, the Metal halogen lamp of what at present great majority used is all 1000W ~ 4000W.The light of this light fixture is 360 degree of luminescences, and the light illumination that light fixture is irradiated to fishing areas, the sea place of 40 meters of distances is very little, and optical energy loss is serious.If install a common lampshade additional, then the volume of lampshade can be very huge, is unfavorable for very much installation, transport etc.Meanwhile, the power consumption of this light fixture is very large, the fishing Metal halogen lamp on a fishing boat, 200000W at least, at most 480000W.Huge illumination power consumption, proposes harsh requirement to the power of fishing boat, adds the consumption of fuel, increases the power of generator, improves the cost of fishing.
Summary of the invention
For above-mentioned situation, the invention provides a kind of LED lamp with reflection unit, to reduce the energy consumption of light fixture, improve the illumination of light fixture simultaneously, reduce cost during large-scale application.
The LED lamp with reflection unit of the present invention, has the horn-like reflection unit that a bottom area is less than apex area, and the bottom end in reflection unit is provided with the light source that the LED to the bright dipping of reflection unit top arranges; The inside circumference of reflection unit is provided with reflecting surface, and described reflecting surface is at least two sections that arrange successively along reflection unit light direction, and the cone angle of adjacent segment reflecting surface is different; Base and the wire hole of band mounting structure is provided with in the bottom of reflection unit.Usually hundreds of LED can be arranged into array light source, then reflection reinforcement is carried out in the bright dipping of the horn-like reflection unit pair array light source being provided with reflecting surface by inside circumference.Particularly when described reflecting surface is the circular cone or circular platform type reflecting surface that arrange in horn-like reflection unit, the cone angle of described reflecting surface, refers to the coning angle of its correspondence.
Because the common rising angle of LED is between 115 ~ 120 degree, about 40 ~ 50 degree can be reached again by the rising angle of light after reflection unit, significantly can increase directionality and the illumination of light like this, simultaneously also because the energy conservation characteristic of LED, the overall power consumption of light fixture also can significantly reduce.Be applied as example still with marine fisherman, light fixture of the present invention is hung on fisherman distance 10 meters, sea eminence, overhang region is 10 meters × 2 meters, and the both sides of hull can respectively hang 80 ~ 100.The optical axis of light fixture and the angle on sea are 80 degree ± 5 degree.2 ~ 3 light fixtures of light fixture overhang region lengthwise edge can deflect 16 degree ~ 20 degree, for being illuminated at the edge (as 50 meters, both sides widthwise edges) of fishing areas to the fringe region of fishing areas.Above-mentioned reflection unit reduces the light intensity immediately below vertical irradiation to sky and light fixture to greatest extent, makes the light of light fixture 90% to be irradiated to fishing areas, thus has increased substantially the illumination of fishing areas.Simultaneously due to the controllability of LED light source, can also according to the hobby of different fish to color, select the copper base of LED that different-colour, different color can be housed, form the LED light source of different-colour and color.Except the fishing of sea, according to the setting of different reflection units and reflecting surface, LED lamp of the present invention equally also can be widely used in the multiple occasions such as industrial and mineral illumination, commercial lighting, square and court illumination.
According to different application occasion or purposes, different rising angle requirements is had to light fixture.Beam angle is commonly referred to as light source or light fixture when luminous intensity is 50% of the brightest intensity, the angle of light source or light fixture light beam.Rising angle is less, the cone angle change of reflection unit interior reflective surface greatly, according to varying in size of light fixture beam angle, reflection unit inside circumference axially sets gradually at least two sections of reflectings surface along reflection unit, with the adjustment between facilitating factors such as irradiation distance, scope, illumination, adapt to, take into account and meet different use needs.Such as, be usually less than the rising angle of 30 degree, the cone angle of reflecting surface changes greatly, and needs to arrange multistage reflecting surface, can be set to fish scale shape when rising angle is little to reflecting surface when 20 degree; Be greater than 50 degree of rising angles, the cone angle change of reflecting surface is little, only establishes one section of reflecting surface to be also allow in some cases.Generally speaking, the reflection unit being greater than 40 degree of beam angles need arrange two sections of reflectings surface, and the reflection unit being less than 30 degree of beam angles then arranges multistage reflecting surface, according to different use occasions or needs, arranges the multistage reflecting surface with different rising angle.Meanwhile, according to the intrinsic brilliance of certain regional extent, strong and weak and demand brightness, is arranged accordingly to the size of the reflecting surface of correspondence.
Preferably, described reflecting surface be the radial section of each rib on the many prismatics reflecting surface, particularly reflecting surface that arrange along reflection unit inside circumference all in regular polygon, as equilateral triangle, regular hexagon, dodecagon etc.The reflecting surface of many prismatics is softer than the bright dipping of smooth reflecting surface and even, is also easier to the reflection angle adjusting local.For many prismatics reflecting surface all in regular polygon of the radial section of many prismatics, particularly each rib, the cone angle of reflecting surface described in it, refers to cone angle that in the pyramid of its correspondence or terrace with edge, seamed edge the is formed coning angle of its corresponding external circular cone or round platform (also i.e.).
Further, the cone angle of each section of reflecting surface reduces successively along reflection unit light direction.Reflecting surface near reflection unit bottom is mainly used in the rim ray converging LED light source beam angle, and the reflecting surface on the top of reflection unit is mainly used in the light converging the large beam angle of LED light source.
On this basis, preferably, the length of each section of described reflecting surface increases successively along reflection unit light direction.
Concrete, the reflecting surface of described reflection unit is coated with aluminium film, and surface roughness is Ra0.125 ~ Ra0.025, and the reflectivity of reflecting surface can be made like this to be greater than 82%, improves reflection efficiency.
Further, the bottom of described reflection unit is provided with components and parts guard shield and hermetically-sealed construction, with protective device, light source not by pollution or corrosion and damage such as the dust in environment, steam or other materials.Hermetically-sealed construction includes is located at the hermetically-sealed constructions such as rubber ring bottom reflection unit.
