Description
Technical field
The utility model belongs to Optical devices technical field more particularly to a kind of applied to lens, the light emitting module of washing wall
And wall lamp.
Background technique
With the lasting progress of Development of China's Urbanization, especially in terms of city public lighting, tourist attraction
Construction on, the requirement for lighting rendering effect is higher and higher, and a critically important factor is exactly in lighting rendering effect
Wash wall effect.
TIR lens are mostly used in existing wall lamp greatly, the light that light source issues is changed into collimation light emission by TIR lens
Out.As shown in Figure 1, light a part that light source issues refracts to collimation by the transmission plane (i.e. incidence surface) of TIR lens
Optically focused, another part reflex to Quasi-straight light-focusing by after the Cylinder Refraction of lens bottom, then through fully reflecting surface.On as shown in Fig. 2,
The light for stating Quasi-straight light-focusing is projected through the light-emitting surface of lens, since the light-emitting surface of lens is smooth mirror surface, most of collimated light
Refraction or refraction angle very little do not occur for line, and therefore, the light projected from light-emitting surface is still collimated light.Due in wall lamp
Had by the light emitting module that TIR lens are constituted multiple, and is arranged according to array, therefore, the light mixing of injection will appear beam streaks sense,
That is, light is uneven near the light-emitting surface of wall lamp, washes that wall is ineffective, to influence whole lighting engineering effect.
Utility model content

A kind of wall lamp is also disclosed in the utility model, including the linear array being made of above-mentioned light emitting module；Described straight
In linear array, the pearl face on the light-emitting surface applied to the lens for washing wall is located on the same line.
The lens, light emitting module and wall lamp provided by the utility model for being applied to wash wall, by the pure of existing TIR lens
Mirror surface light-emitting surface carries out part pearl surface treatment, forms the light-emitting surface of TIR lens by mirror surface and pearl face two parts, and pearl face is one
A continuous arch surface, at the one side edge of entire light-emitting surface.Due to the part, pearl face can change anti-by fully reflecting surface
Therefore the direction for the collimated ray penetrated is applied in wall lamp, simultaneously when arranging above-mentioned TIR lens according to linear array
When pearl face is mounted against a wall, will not occur the beam streaks of a lot of as existing wall lamp, and can by collimated ray into
Row refraction, realizes the diverging of light, to achieve the purpose that even light mixing near light-emitting surface.And another part mirror surface of light-emitting surface,
Still for being emitted collimated ray, wall effect is washed in realization.As it can be seen that technical solution provided by the utility model, uniform in light emission, Xi Qiang
Effect is good, can be improved whole lighting engineering effect.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
Fig. 3 is the structural schematic diagram of the utility model embodiment, including：TIR lens；The TIR lens include：The bottom of positioned at
The incidence surface (incidence surface is also referred to as transmission plane) in portion, the light-emitting surface positioned at top, the fully reflecting surface positioned at side；The TIR
The light-emitting surface 1 of lens is to combine the disc formed by mirror surface 11 and pearl face 12；The pearl face 12 is continuous；The pearl face 12 is
Arch, the coincident of the bowed arc and the light-emitting surface 1；12 area of pearl face is not less than 1 area of light-emitting surface
1/3, and 12 area of pearl face be not more than 1 area of light-emitting surface 1/2.Preferably, 12 area of pearl face is 1 face of light-emitting surface
Long-pending 1/2.
In the present embodiment, the incidence surface 2 of the TIR lens is axisymmetric curved surface；The fully reflecting surface 3 of the TIR lens is
Axisymmetric curved surface.The central area of TIR lens bottom is equipped with recess 4, for placing light source 5；The side wall 41 of the recess 4
Slope inwardly from the bottom up, that is, be recessed 4 side wall 41 be the standard cylinder with certain pattern draft.
A kind of light emitting module is also disclosed in the utility model, including：Light source and the above-mentioned lens for being applied to wash wall.Light source is set
In the recess 4 of above-mentioned TIR lens bottom, and it is located at bottom centre position, the light source is preferably LED light.Such as Fig. 5 institute
Show, the light that LED light issues is divided into two parts and enters TIR lens：A part of light passes through the axial symmetry plane of incidence of TIR lens bottom
(i.e. transmission plane) reflects, and achievees the purpose that optical path optically focused collimates；Side wall 41 of another part light by recess 4 is rolled over
After penetrating, the purpose of optical path optically focused collimation is reflected up to using fully reflecting surface.When two parts collimated light path is projected by light-emitting surface 1
When, the light beaten on pearl face 12 can be dissipated because of refraction, and the light beaten on mirror surface 11 remains as collimated ray.Such as
This, by above-mentioned light emitting module according to arranged in a straight line, and the pearl face on light-emitting surface is assembled by metope, then above-mentioned beat on pearl face and
The beam streaks of a lot of, the i.e. light-emitting surface in entire light emitting module would not occur as currently existing scheme in the light of diverging
It is not in nearby dark space, to keep the hot spot near light-emitting surface more uniform；Meanwhile beating the light collimated on mirror surface still
It can so show and wash wall effect.
A kind of wall lamp is also disclosed in the utility model, including the linear array being made of above-mentioned light emitting module；Described straight
In linear array, the pearl face 12 on the light-emitting surface 1 applied to the lens for washing wall is located on the same line.Wall is washed during installation
When lamp, pearl face 12 is assembled by metope, can show and more uniform wash wall effect.
Further, it is also possible to reach the technical effect of the utility model by following six kinds of modes：1, sunk surface 1/3~
1/2 frosted, and 1/3~1/2 plaited surface of fully reflecting surface；2,1/3~1/2 pearl face of sunk surface, and 1/3~1/2 plaited surface of fully reflecting surface；
3,1/3~1/2 frosted of sunk surface, and 1/3~1/2 pearl face of light-emitting surface；4,1/3~1/2 striped of sunk surface, and light-emitting surface 1/
3~1/2 pearl faces；5,1/3~1/2 frosted of sunk surface, and 1/3~1/2 frosted of light-emitting surface；6, sunk surface 1/3~1/2
Line, and 1/3~1/2 frosted of light-emitting surface.
The lens, light emitting module and wall lamp provided by the utility model for being applied to wash wall, by the pure of existing TIR lens
Mirror surface light-emitting surface carries out part pearl surface treatment, forms the light-emitting surface of TIR lens by mirror surface and pearl face two parts, and pearl face is one
A continuous arch surface, at the one side edge of entire light-emitting surface.Due to the part, pearl face can change anti-by fully reflecting surface
Therefore the direction for the collimated ray penetrated is applied in wall lamp, simultaneously when arranging above-mentioned TIR lens according to linear array
When pearl face is mounted against a wall, will not occur the beam streaks of a lot of as existing wall lamp, and can by collimated ray into
Row refraction, realizes the diverging of light, to achieve the purpose that even light mixing.And another part mirror surface of light-emitting surface, still for going out
Collimated ray is penetrated, wall effect is washed in realization.As it can be seen that technical solution provided by the utility model, uniform in light emission, good, energy of washing wall effect
It is enough to improve whole lighting engineering effect.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
