Abstract
The invention relates to lenses and discloses an LED wall washer lens. The LED wall washer lens comprises a lens body of an incomplete conical table structure, a recessed LED accommodating space is reserved on the narrow bottom surface of the lens body, the inner surface of the accommodating space serves as a light incident surface, the wide sector top surface of the lens body serves as a main emergent surface, a conical surface projection opposite to the lens body is arranged below a notch of the main emergent surface, a conical surface serves as an auxiliary emergent surface, and other sides of the lens body serve as reflecting surfaces. The LED wall washer lens has the advantages of high LED luminous efficiency, illumination uniformity and large illumination angle.
Description
Technical field
The present invention relates to lens, especially relate to the LED wall lamp lens that a kind of LED of making luminous efficiency is high, illuminance is even, irradiating angle is large.
Background technology
Wall lamp, as its name suggests, allow light wash metope as water, also mainly the use for doing building decoration illumination, be used in addition sketching the contours the profile of heavy construction, because LED has the features such as energy-conservation, light efficiency is high, rich color, life-span are long, so the wall lamp of other light sources is replaced by LED wall lamp gradually at present.
Traditional wall lamp, bridge railing lamp, billboard irradiate apart from too short, and light utilization is low, for example luminous flux of light source 100lm, and by lens outgoing 90lm, actual being irradiated on shadow surface only has 40～50lm, therefore efficiency only has 40%～50%.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the invention is to provide the LED wall lamp that a kind of LED of making luminous efficiency is high, illuminance is even, irradiating angle is large lens.
The present invention realizes by following technical measures, a kind of LED wall lamp lens, comprise lens body, described lens body is incomplete taper platform structure, there is the LED accommodation space of an indent the thinner bottom surface of lens body, the inner surface of this accommodation space is light entrance face, the wider fan-shaped end face of described lens body is main exit facet, there is a taper surface projection reverse with lens body the breach below of described main exit facet, this taper surface is auxiliary exit facet, and other side of described lens body is reflecting surface.
Concrete, described LED accommodation space is a taper.
Concrete, described main exit facet is divided into middle main exit facet and is symmetrically placed in left main exit facet and the right main exit facet of two sides.
Preferably, the main exit facet surface uniform in described centre is provided with many and is parallel to each other and the wavy bulge of vertical wall, or the surface uniform of left main exit facet and right main exit facet is provided with many and is parallel to each other and the wavy bulge of vertical wall, or the surface of middle main exit facet, left main exit facet and right main exit facet is all evenly provided with many and is parallel to each other and the wavy bulge of vertical wall.Be beneficial to light scattering and go out, make radiation response more even.
As a kind of optimal way, the surface uniform of described auxiliary exit facet is provided with many and is parallel to each other and the wavy bulge of parallel metope.Be beneficial to light scattering and go out, make radiation response more even.
As a kind of optimal way, described main exit facet forwards with two sides are along being stretched into a long side.More in forming each other a lens module.
As a kind of optimal way, anti-reflection film is posted or scribbles on the surface of described main exit facet and auxiliary exit facet.Strengthen the light transmission of main exit facet and auxiliary exit facet.
As a kind of optimal way, reflective membrane is posted or scribbles on the surface of described reflecting surface.Strengthen the reflective of reflecting surface.
Preferably, described lens body is optical glass lens or the plastic cement lens that light transmittance is greater than 93%.
As a kind of optimal way, described main exit facet is to metope low dip.
The point light that the present invention sends LED is disperseed to inject in lens body by the plane of incidence, from top, main exit facet scatters out with dual side-edge middle stronger light upward, light near metope is launched along metope upward from auxiliary exit facet, the light of outermost side also scatters out with dual side-edge from top exit facet after reflecting by reflecting surface upward, thereby the light that main exit facet and auxiliary exit facet penetrate by combined crosswise make whole emergent ray utilization rate high, evenly disperse, reach the effect that luminous efficiency is high, illuminance is even, irradiating angle is large.And can reach different radiation responses by adjusting the size of main exit facet and covering of the fan and the radian of middle main exit facet, left main exit facet and right main exit facet surface wave shape wave projection.
