Description

A kind of LED wall wash lamp lens and wall lamp
Technical field
The utility model relates to field of light fittings more particularly to a kind of LED wall wash lamp lens and wall lamp.
Background technique
Wall lamp allows light to wash metope as water as its name suggests, is that a kind of outdoor building brightening illumination is common linear The outer profile of lamps and lanterns, the decorative lighting and building that are mainly used for building sketches the contours, and LED wall wash lamp is because it is efficient, energy saving, color is rich Rich, service life length, can be achieved multi-effect and be widely used in various places control mode diversification, as municipal building, business are comprehensive Zoarium, enterprise building, historical building, public place of entertainment etc..Existing wall lamp mainstay two types:
1. light distribution symmetric design, such design angle then washes wall insufficient height greatly very much, and angle is too small, washes wall height satisfaction, But beauty is reduced occurring light and dark striped at lamps and lanterns;
2. asymmetric light distribution designs, such design angle divides both direction, and the angle changing rate for being parallel to metope is big, perpendicular to The differences in angle of metope is smaller, and such design solves the light and dark stripes problem in bottom, but it is obviously insufficient to wash wall height.
Therefore, it is necessary to one kind have substantially no effect on wash wall height in the case where, eliminate bottom light and dark stripes problem Wall lamp.
Summary of the invention
The utility model is for washing wall height in the prior art and the shortcomings that bottom light and shade can not uniformly get both, provide one Kind LED wall wash lamp lens and wall lamp.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:
A kind of LED wall wash lamp lens, including integrally formed lens body, lens body include mounting portion and light out part, Mounting portion is equipped with the installation cavity for mounted LED lamp, is additionally provided with incidence surface and light-emitting surface, and light out part is set in parallel equipped with multiple That sets goes out light beam, and light beam includes cylinder out, is all plane of same size between every two adjacent light beam out, light-emitting surface is by column Face and plane form, and the adjacent plane width gone out between light beam is L1, the width of cylinder is L between adjacent plane2, L1With L2Width ratio be 1:1~1:3.According to L1And L2Width ratio size influence light distribution oblique emergent light and straight emergent light ratio Example, to influence the uniformity of adjacent lamp light and lamps and lanterns wash the height of wall, the application is narrowed apart from light source distant place light distribution, makes light Line is more uniform when projecting and height is more increased;The material of lens is the transparent material of PC or PMMA.
Preferably, incidence surface is the free form surface to installation cavity sunken inside.Free form surface has specific radian, specific root Corresponding cooperation is made according to the change of the LED light used to change.
Preferably, each cylinder is identical free form surface.Free form surface has specific radian, with specific reference to using The change of LED light and the radian of incidence surface make corresponding cooperation and change.
Preferably, the side wall of mounting portion is total reflection free form surface.
Preferably, the diameter of mounting portion outlet is L3, L3Length be 4.9mm;The height of mounting portion is H, and H is 10.5mm。
Preferably, the side wall of installation cavity and horizontal plane institute's angle are α, α is 87 °.
Preferably, L1Width be 0.66mm, L2Width be 1.54mm.
Preferably, the side wall of the side wall of installation cavity, mounting portion, incidence surface, plane, cylinder are by changing free form surface Curvature, L1And L2Angle value of the width than, α and the adjustment that cooperates with light distribution.By light intensity curve as it can be seen that light intensity curve most High light intensity can be higher, and distribution curve flux is also more uniform with existing wall lamp, and height is higher.
Preferably, further including the LED wall wash lamp lens, LED lamp is mounted in installation cavity, LED wall wash lamp lens It is mounted in lamp housing.
Preferably, installing one or more LED wall wash lamp lens in lamp housing.It can be the single wall lamp used, The full page wall lamp that can be used for whole multiple lamp bodies.
The utility model has significant technical effect: going out light by lens surface due to using above technical scheme Structure design improves, to adjust with light distribution, in light source nearby larger the improvements bottom uniformity of light-emitting angle, apart from light source distant place Light distribution narrows, and light intensity is concentrated to promote irradiation height, since nearby to promote luminous flux consumed by brightness less for light source, so irradiation The light of distant place, which need to only disperse less a part, can be obviously improved light source nearby brightness, though while irradiating the angle of distant place angle It is small, but because equally can very uniformly apart from increasing.Under same light flux conditions, the light distribution design of the utility model can wash wall height Du Genggao, while the brightness of bottom light is more uniform.
