Abstract
The invention discloses an anti-glare floodlight, comprising a reflector, an LED light source and a transparent member. A circle of light transmitting anti-glare device is arranged on the edge of a light outlet of the reflector; the anti-glare device is arranged behind the transparent member, and a shielding angle Alpha formed is 10 to 45 degrees. The invention provides the anti-glare floodlight with simple structure, reliable manner and relatively low cost, solves the glare problem of a light without lowering the central luminance and is applicable to many kinds of lights.
Description
Technical field
The invention belongs to field of illumination lamp technology, relate to a kind of floodlight, relate in particular to a kind of anti-glare floodlight.Be mainly used in the spot light of high power, high light flux.As: the Metal halogen lamp of transparent cell-shell, the high-pressure mercury lamp of transparent cell-shell.
Background technology
In order to reach light distribution effect, the luminous intensity distribution angle of Flood lamps and lanterns is generally bigger, and the position of light source is more shallow.Because the horizontal view angle of human eye is 170 °, the vertical angle of view is 60 °.Wherein the upward angle of visibility of vertical angle of view is 15 °.If the more shallow light direct projection human eye that just has in the position of light source; Will produce dazzle and cause bad vision reflection; In order to prevent and treat dazzle; Flood lamps and lanterns requires that certain lamp shielding angle is arranged, and lamp shielding angle is claimed shielding angle again, is meant that the outer of light source luminescent body a bit and the line at light fixture light-emitting window edge and the angle that passes through between the horizontal line at light source light center.Common lamp shielding angle is that a circle shrouding is set at the light-emitting window place, light is covered, but strengthening lamp shielding angle can reduce Luminaire efficiency.
Summary of the invention
The technical problem that the present invention will solve is; To the above-mentioned defective of prior art, provide a kind of simple in structure, mode is reliable, lower-cost anti-glare floodlight, the present invention is on the basis that does not reduce center illumination; Solve the glare problem of light fixture, applicable to multiple light fixture.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-glare floodlight; Comprise reflector, led light source, transparent member; Said reflector light-emitting window edge is provided with the antiglare equipment of a circle printing opacity, and said antiglare equipment is arranged on the rear of transparent member and the lamp shielding angle α of its formation is 10～45 °.
Said antiglare equipment is the anti-dazzle shield that surface that light transmissive material is processed has concaveconvex structure, and the lamp shielding angle α that anti-dazzle shield forms is 30～45 °.
Said light transmissive material is the macromolecular material of printing opacity.
Said anti-dazzle shield is joined together to form by anti-dazzle of a plurality of astigmatism.
Said anti-dazzle is anti-dazzle, and said anti-dazzle shield is anti-dazzle the arrangement one circle formation at reflector light-emitting window edge of many printing opacities.
Said anti-dazzle is fixed on the said reflector through fixture.
Said anti-dazzle arrangement leaves the gap between adjacent anti-dazzle at grade, and anti-dazzle cross section is circle, semicircle or polygon.
Said anti-dazzle shield has the light-passing board of bar shaped rib for the surface, or has the light-passing board of the space pattern on the anti-dazzle shield of protrusion surface.
Anti-glare floodlight tool of the present invention; It is the antiglare equipment that on the light-emitting window of light fixture, increases printing opacity; Antiglare equipment covers a circle at the light-emitting window of light fixture; Make lamp shielding angle α remain in 10～45 ° the scope, avoid the direct-view of human eye, thereby reduce the bad vision reflection that light source direct projection light causes human eye light source.And because antiglare equipment is printing opacity, so antiglare equipment disperses light to reduce direct projection on the one hand, and printing opacity can too much not reduce the luminous efficiency of light fixture again on the other hand.The present invention is simple in structure, mode is reliable, cost is lower, on the basis that does not reduce center illumination, solves the glare problem of light fixture, applicable to multiple light fixture.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in Figure 1; A kind of anti-glare floodlight; Comprise reflector 1, led light source 2, transparent member 5, said reflector 1 light-emitting window edge is provided with the antiglare equipment 3 of a circle printing opacity, the size of the width decision lamp shielding angle of antiglare equipment 3; The lamp shielding angle α that antiglare equipment of the present invention forms is 10～45 °, can prevent that the light source of high brightness from causing direct glare.Owing to adopt the antiglare equipment of printing opacity, the ability disperse light reduces the chance of light direct projection human eye on the one hand, and the antiglare equipment printing opacity can too much not reduce the luminous efficiency of light fixture again on the other hand.Said antiglare equipment 3 is arranged on the rear of transparent member 5, and transparent member 5 has played the effect of protection antiglare equipment 3, also makes the light fixture appearance looks elegant.The surface that said antiglare equipment 3 is processed for light transmissive material has the anti-dazzle shield of concaveconvex structure; The surface of anti-dazzle shield is a concaveconvex structure; Make anti-dazzle shield play the effect of astigmatism, avoid light directly to inject in the eye, and the lamp shielding angle α that antiglare equipment 3 forms is preferably 30～45 °.Can play anti-dazzle effect preferably in this scope, concrete lamp shielding angle can be multiple angles such as 10 °, 20 °, 30 °, 40 °, 45 °, and the high more antiglare effect of angle is good more, but should not surpass 45 °, otherwise can too much reduce the luminous efficiency of light fixture.
The light transmissive material of antiglare equipment 3 is selected the macromolecular material of printing opacity for use, PC for example, PMMA, macromolecular material have the light weight printing opacity evenly, be easy to produce the advantage of multiple shape.Anti-dazzle shield of the present invention can be a various ways; A kind of is to form uneven structure on the surface of transparent anti-dazzle shield; For example frosted, convexity, design space pattern etc. are set; Another kind is to adopt a plurality of anti-dazzle compositions that can carry out scattering to light, and anti-dazzle of present embodiment is anti-dazzle, and anti-dazzle shield is anti-dazzle the arrangement one circle formation at reflector light-emitting window edge of many printing opacities.Anti-dazzle arrangement leaves the gap between adjacent anti-dazzle at grade, and the gap increases lamp luminescence efficient, but center illumination also can not stayed the gap when enough.Anti-dazzle of present embodiment is arranged in parallel each other, and anti-dazzle all be fixed on the reflector 1 through clamp or other fixtures, and anti-dazzle cross section can be circular, semicircle or polygon, and these shapes can both play the anti-dazzle effect that disperses to light.
Anti-dazzle shield of the present invention can also adopt the surface to have the light-passing board of bar shaped rib; The cross section of bar shaped rib can be multiple shape; For example semicircle, triangle, polygon, or have the light-passing board of the space pattern on the anti-dazzle shield of protrusion surface, because space pattern is arranged; Light is also formed dispersion, played anti-dazzle effect.
