The specific embodiment
Please refer to Fig. 2, be the first embodiment of the present invention, wherein offer a perforation 702 on the cover body of lampshade main body 701, its interior arrangement one lamp socket 703, and an illuminator 704 is installed on obtains power supply on this lamp socket 703 and luminous.
Lampshade main body 701 inside with upper part, form a snoot 708 at dotted line 709, and it can be parabolic curve or part elliptic curve, and this legend shows with parabolic curve.Snoot 708 tops also offer a perforation, pass for the illuminator 704 that is fixed in the lampshade main body 701.
Lampshade main body 701 inside in dotted line part below 709, form a light distribution curve reflection shield 705, and it is to be fixed in the lampshade main body to be connected with snoot 708.
Lampshade main body 701 belows, with head one printing opacity sheet material 706, this printing opacity sheet material 706 is installed on lampshade main body light illumination end, and with reflective thing 707 fixtures of a bullet in these printing opacity sheet material 706 inboards; The vertex of a cone of the reflective thing 707 of this bullet is towards illuminator 704.And parabola snoot 708 can be concentrated on illuminator 704 irradiation light the reflective thing 707 of below bullet and make light refraction reflect the field of illumination again to reflection shield 705.
Light distribution curve reflection shield 705 is to be connected by the number plane to combine curve, the size on these planes and angle all desire to reflex to the formed angle of reflected ray of certain particular block according to incident ray and on this plane, and calculate this plane and horizontal line relative angle and size by the optical reflection principle.
Illustrate it, please refer to Fig. 3, be light distribution curve reflection shield 705 certain when amplifying display segment 203, one fixed-direction incident raies 107 and will reflex to a specific desire illumination block 114 through 105 surfaces, a plane wherein, incident ray 107 forms an angle f117 with reflection ray 108; Leading pushing manipulation according to the principle of reflection utilization calculates: f11 ÷ 2=incidence angle a115=angle of reflection b116, and this can locate normal 113 correct angles, and normal is perpendicular to plane 105 again, can make the angle e112 of plane 105 relative horizontal lines 111.
Printing opacity sheet material 706 has several critical angles, and having one side at least is the number grating, the gap of grating, angle, specification, shape design according to the optics critical angle principle of these printing opacity sheet material 706 materials, control illuminator 704 does not directly penetrate this printing opacity sheet material directly into incident angle of the entering ray greater than this critical angle becomes total reflection, other is non-directly to penetrate this printing opacity sheet material directly into incident angle of the entering ray less than this critical angle by illuminator 704.
Please refer to Fig. 4 and Fig. 4 A, the printing opacity sheet material 706 in Fig. 2 can be a circular ring-type original screen panel 401.Referring to Fig. 4 B, circular ring-type original screen panel 401 wherein one side is provided with ring of numbers shape grating 403, and another side also can be grating or can be plane 402, and this legend shows with the plane.
Please refer to Fig. 5 and Fig. 5 A, the printing opacity sheet material 706 in Fig. 2 also can be a square strip original screen panel 501.Referring to Fig. 5 B, strip original screen panel 501 wherein one side is provided with several shape gratings 503, and another side can be grating and also can be plane 502, and this legend shows with the plane.
Grating space, angle, the shape of two kinds of shown difformity printing opacity sheet materials are not quite similar in Fig. 4 and Fig. 5, and its correct data is to control it when shining this grating according to each road different angles incident ray for penetrable or for total reflection; When will to make light be penetrable, design made its angle of incidence of light go out grating less than the critical angle refraction of this printing opacity sheet material; Otherwise in the time of will making light not penetrable, design makes its angle of incidence of light be total reflection greater than the critical angle of this printing opacity sheet material.
Illustrate it, see also Fig. 6, the critical angle of acryl printing opacity sheet material 803 is 42.15 °.And when secondary reflecting to transparent acrylic material sheet material 803 planes, produce refraction from wherein one light 802 that light source 801 irradiates, incidence angle θ 1 804 is 41.75 ° during to sheet material 803 another side gratings, because of its less than 42.15 ° of critical angles, enter the field of illumination so reflect sheet material 803 again; Other angles of incidence of light θ 2 to θ 5 is respectively 37.72 °, 38.91 °, 28.34 °, 22.64 °, all less than 42.15 ° of critical angles, enters the field of illumination so reflect sheet material 803 all again.
Reflect and when another road light 805 that light source 801 irradiates arrives transparent acrylic material sheet material 803 planes, produce, incidence angle θ 6 806 is 42.83 ° during to sheet material 803 another side gratings, because of its greater than 42.15 ° of critical angles, can directly not penetrate sheet material and enter the field of illumination so be the total reflection state; Other angles of incidence of light θ 7 and θ 8 are respectively 43.46 ° and 42.72 °, all greater than 42.15 ° of critical angles, can directly not penetrate sheet material and enter the field of illumination so be the total reflection state.
By the explanation among Fig. 6, the present invention installs parabolic curve or part elliptic curve snoot 708 in lampshade as can be known, light can be concentrated on the reflective thing of below bullet 707 surfaces; And light distribution curve reflection shield 705 is arranged in a combination with specific angle by the number plane, can reflect light to predetermined irradiation block, reaches the equally distributed effect of field of illumination brightness; And be positioned at the reflective thing 707 of bullet under the light source and light reflect project again the desire block that throws light on more than secondary, so more can precisely control light and shine a certain particular block.
In addition, printing opacity sheet material 706 is the illuminated area cover body, some surfaces of this printing opacity sheet material have the grating that several different angles are arranged, the angle of incidence of light perseverance that some special angle was injected when these gratings can be controlled light by this printing opacity sheet material 706 is greater than the critical angle of this transparency, make this light be total reflection effectiveness, this can be avoided can looking at the generation of light source bright spot straight at any angle eyes and dazzle luminous effect, and the light luminance that transmits transparency is weakened, and reaches energy-saving effect.
So, the present invention really can reach the energy-conserving action that field of illumination brightness is even, the luminance loss is minimum, can avoid illuminator 704 lights to produce glare phenomenon again.
See also Fig. 7, be the second embodiment of the present invention.Offer a perforation 602 on the cover body of lampshade main body 601, its inside is equipped with a lamp socket 603, and an illuminator 604 placed obtains power supply on the lamp socket 603 and luminous.One parabolic curve or part elliptic curve snoot 608, this legend shows that with parabolic curve its top is also offered a perforation and passed for the illuminators 604 that are fixed in the lampshade main body 601.One light distribution curve reflection shield 605 is fixed in the lampshade main body 601 and is connected with snoot 608.Lampshade main body 601 underside devices one printing opacity sheet material 606, and with reflective thing 607 fixtures of a bullet in printing opacity sheet material inboard, and its vertex of a cone is towards illuminator 604.
Parabolic curve or partly elliptic curve snoot 608 and light distribution curve reflection shield 605 are with the design among first embodiment, the lampshade made of mode really can reach the energy-conserving action that field of illumination brightness is even, the luminance loss is minimum according to this.
