In order to illustrate technical solution described in the utility model, carried out specifically below in conjunction with specific accompanying drawings and embodiments
It is bright.
It please refers to Fig.1, Fig. 3, Fig. 6 and Fig. 7, the utility model embodiment provides a kind of wall-washing lamp, is ensureing to wash wall effect
Eliminate or reduce dazzle in the case of fruit, the wall-washing lamp include at least light bulb 10, the light source 20 that is set in light bulb 10 and
The reflector 30 being set in light bulb 10;Light bulb 10 is at least used to provide outer protection shell for lamps and lanterns and installs other component
Carrier is assembled, light source 20 and reflector 30 are installed in the light bulb 10, it will be understood that light bulb 10 offers corresponding cable-through hole, uses
In across conducting wire, light source 20 and external circuit are connected, ensure that light source 20 can shine.Reflector 30 is for light source
20 light sent out carry out the element of light distribution, and reflector 30 is including reflector bodies 31 and is set to 31 surface of reflector bodies
There is the reflecting surface 32 of the reflecting surface 32 of free form surface shape, free form surface shape an eccentric focus, the luminous point of light source 20 to be set to
Eccentric point of intersection;Wherein, reflector bodies 31 are an entity structure with certain volume, and major function is to provide to reflection
The support in face 32, for reflective.It is appreciated that the reflecting surface 32 is the part for determining light distribution effect, the shape of reflector bodies 31
Shape need not be limited strictly, be typically designed to the shape similar with reflecting surface 32, convenient for making certainly.In one embodiment, reflecting surface
32 and reflector bodies 31 are integral structures, i.e., reflector bodies 31 are processed into satisfactory reflection on one side towards light source 20
Face 32, in another embodiment, reflecting surface 32 are formed at satisfactory film of the reflector bodies 31 towards 20 one side of light source
Structure, the requirement generally include the requirement of surface roughness, the requirement of reflecting angle and the requirement of size etc..In addition,
Light bulb 10 offers slit light-emitting window 11, and the light that light source 20 is sent out reflects to form reflected light by reflecting surface 32, reflected light in
Intersect at slit light-emitting window 11 and in a formation section light under cutting light action for slit light-emitting window 11.The reflected light is in infall
Cross-sectional area is the minimum area on entire reflected light path, and the slit light-emitting window 11 designed herein can accomplish very little, more
The installation environment for adding suitable wall lamp makes the light source 20 of wall-washing lamp be hidden in light bulb 10, and slit light-emitting window size is small,
So that light source 20 is invisible in outside, light all exports after the reflection of reflector 30, there will not be the light that light source 20 is sent out
Line direct projection comes out, and the light projected by slit light-emitting window 11, which is radiated to present on metope, cuts light effect, can effectively reduce photograph
Penetrate the light in the external space of metope.
The wall-washing lamp is installed on the erecting bed of ceiling, and the structure of the erecting bed is not limited, slit light extraction
For mouth 11 towards ground, the light that the light source 20 of the eccentric focal point of reflecting surface 32 is sent out can be in slit after the reflection of reflecting surface 32
At formula light-emitting window 11 intersect, by slit light-emitting window 11 to light cut light action so that the cross-sectional shape of emergent light with
The shape of slit light-emitting window 11 matches, that is, has apparent contour line, without the miscellaneous of more random wide-angle
Astigmatism line, meanwhile, light projects from slit light-emitting window 11 and is straightline propagation, will not be irradiated to ceiling 40, therefore, cuts light
It is projeced into the metope 50 vertical with ceiling 40, and 40 region of ceiling between lamps and lanterns and metope 50 at an angle
Illumination is not had, ceiling 40 and metope 50 is made to form apparent brightness contrast.Meanwhile the dispersion angle for cutting light is limited and sending out
It is zero or few to dissipate the light other than angle, will not form dazzle, improve the aesthetics and user experience for washing wall.
The technique effect of the wall-washing lamp is:Reflector 30 is equipped with free form surface shape reflecting surface 32, and light source 20 is set to it
In eccentric focus, while the infall for corresponding in light bulb 10 reflected light opens up slit light-emitting window 11, passes through slit light extraction
11 pairs of beam shapes of mouth are adjusted, and are formed and are cut a light irradiation metope 50.On the one hand the apparent hot spot in edge is formd, wall is washed in improvement
On the other hand effect limits the dispersion angle of light beam, eliminates the irregular veiling glare of wide-angle, light is avoided to be irradiated to wall
Region except face 50, and then dazzle is eliminated or reduces, promote user experience.
In the present embodiment, the shape of reflecting surface 32 determines eccentric focal position and slit light-emitting window 11 with respect to this partially
The position of anxious point can obtain each structural parameters by the simulation of corresponding light path, and different 32 shapes of reflecting surface corresponds to different
20 position of light source and slit light-emitting window 11 position and size, the present embodiment without limit.
