Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
The ellipsoidally polarized wall-washing reflecting cup as shown in fig. 1-7 comprises a body, wherein the body is formed by splicing at least two reflecting cup units, the reflecting cup units are the remaining parts of the elliptical reflecting cup after the parts are cut off, the elliptical reflecting cup where the two reflecting cup units are located has a focus which is overlapped, the focus is a light source installation position, so that light emitted by a light source is reflected by the two reflecting cup units, and then is emitted from the other focus of the elliptical reflecting cup where the two reflecting cup units are located and irradiates in the same plane.
According to the principle of an ellipsoid equation, a light source is placed at one focus of an ellipse equation, and after light passes through an ellipsoidal reflector, all the light is reflected to pass through the other focus of the ellipse.
Therefore, when in use, the light source is installed at the focal position where the two reflecting cup units 11 are overlapped, so that light generated by the light source is reflected by the reflecting cup units 11 and then uniformly irradiates the surface of a wall or an object through the other focal point of the reflecting cup units 11.
The existing wall washing lamp adopts the lens to polarize, when in use, the angle of the polarized light rear part light splitting ray can reach the standard, so that the light is not irradiated on an object, the utilization rate of luminous flux is low, the light can be concentrated in a certain area, other areas have less light, the illumination is uneven, and glare is easy to generate; in addition, as shown in fig. 4 and fig. 5, one of the focuses of the two reflector cup units 11 is overlapped, and the focus is a light source installation position, so that light emitted by the light source can be uniformly emitted into the two reflector cup units 11 and uniformly reflected to an object or a wall surface by the two reflector cup units 11, thereby effectively avoiding that too much light is irradiated in one of the reflector cup units 11, which causes that the light reflected by one of the reflector cup units 11 is more than the light reflected by the other reflector cup unit 11, and uneven illuminance occurs; simultaneously, because light all jets out from another focus at the oval reflection of light cup place at two reflection of light cups, when the people stood in reflection of light cup below, light can not shine eyes position and cause the glare, and the quantity of reflection of light cup unit 11 can be selected according to the difference of user's illumination size in this application in addition, does not restrict its quantity in this application.
Preferably, the included angle between the major axes of two reflection cup units 11 in this application is less than 90 degrees to reduce the illumination angle of this application ellipsometry wall-washing reflection cup, avoid illumination angle too big, comparatively diffused by reflected light, illumination luminance is low.
More preferably, the angle between the major axes of the two reflector cup units 11 is less than 30 degrees.
In addition, for avoiding reflecting the light of going out too concentrated, the inner wall of reflection cup unit 11 is plane of reflection 111 in this application, and plane of reflection 111 comprises a plurality of scales 112, and light will be followed the multi-angle dispersion and jetted out when shining on scale 112, avoids light too concentrated, improves irradiant degree of consistency. Specifically, scale 112 is the ichthyoid setting in this application to can jet out light further fall into the multi-angle, improve irradiant degree of consistency, avoid appearing light dizzy, scale 112 also can adopt multilateral shape in this application certainly, like square, rectangle, hexagon etc..
Meanwhile, in order to facilitate the body 1 to be further provided with the installation part 12, the installation part 12 is arranged at one end of the body 1 far away from the focus, and a user can fix the installation part 12 on a wall or other fixing devices.
In addition, in order to further improve the utilization rate of the luminous flux, the present application is provided with a plurality of light reflecting curved surfaces 121 on the side of the mounting portion 12 facing the focal point, so as to reflect part of the light irradiated on the mounting portion 12 to the object or the wall surface.
As shown in fig. 1 to 3, a wall washing lamp includes the above-mentioned elliptically polarized light wall washing reflective cup and the light source, the light source is disposed at the focus, and the light source is disposed at the focus position, so that the light emitted from the light source can be uniformly emitted into the two reflective cup units 11, and is uniformly reflected to an object or a wall surface by the two reflective cup units 11, thereby effectively avoiding that too much light is irradiated in one of the reflective cup units 11, which causes the light reflected by one of the reflective cup units 11 to be redundant to the light reflected by the other reflective cup unit 11, and uneven illuminance occurs; meanwhile, the arrangement of the reflecting cup is adopted, so that the utilization rate of luminous flux is high.
In addition, fig. 6 is a polar coordinate system diagram of a light distribution curve during an ellipsometric wall-washing reflector simulation experiment according to the present invention; FIG. 7 is a polar coordinate system diagram of a light distribution curve of the ellipsometric wall-washing reflector of the present invention during actual testing. Can discover through experimental simulation and actual test, the light that jets out of this application ellipsometry wall-washing reflection of light cup all concentrates on certain extent, can not too disperse, and light high-usage, and light is even.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
