Embodiment

Blinding free disclosed in the present patent application focuses on luminous and lighting device, and it, which is constituted, is included in optically focused bottle 2 and optically focused bottle 2 Light source 1.As shown in Figure 10, Figure 11, Figure 13, the source light that gives out of light source 1 for being arranged at optically focused 2 axis of symmetry of bottle is projected to Optically focused 2 inner surfaces of bottle, according to principle of reflection, determine optically focused 2 inner surface each point angles of reflection of bottle, make the reflection light of every bit complete Portion, it is accurate focus on the axis of symmetry a bit, the focus point deviates from light source position, and the focus point is configured as the bottle of optically focused bottle 2 The light hole 21 of mouth 20.The light beam that light hole 21 is projected, its light beam cone angle is the beam angle that light hole 21 is projected A, beam angle a determination are main to be calculated according to actual irradiation distance and irradiation area scope are design parameter, therein to shine It is that it is illuminated right that irradiation area is projected to for light beam along beam center line, by the distance of light hole to illuminated object to penetrate apart from h The diaphragm diameter d of elephant.According to the different application field of product, irradiation distance h and irradiation area d specifically are determined, calculating is obtained Beam angle a.

The schematic diagram for being to determine optically focused 2 reflective inner surfaces of bottle shown in Figure 11.Light source therein actually can using LED, Laser lighting lamp etc. is the light source part of unilateral scattered light.Optically focused bottle length is determined according to illuminating lamp actual design size, will be pushed away The bottle inner opposite angle for calculating the beam angle a obtained carries out n deciles, and light source 1 source light, 180 ° of angle of scatterings are equally similarly carried out into n etc. Point, the joining that beam angle a each bisector of vertical angles connects one to one with each bisector of light source angle of scattering, is inner surface Pip, the reflecting surface of each pip is determined according to light reflection principle, and the connection of these reflectings surface is fitted to optically focused bottle inner surface. We understand that n values are bigger, and each road reflecting surface is fitted more smooth, and its machining accuracy is also higher, and spotlight effect is also better.For Optically focused requirement not bery high illuminating product, then need not pursue excessive n values, and n values are chosen suitably, and each axle position of the axis of symmetry is tackled in gathering Light bottle inner surface can form the reflective face ring 22,23 of more obvious multiple tracks, and each reflective face ring in road has corresponding by light source source light Line reflection focuses to the reflecting angle of light hole.Optically focused 2 monnolithic cases of bottle are according to inner surface configuration, its usual body dome, and To the water-drop-shaped of the smooth contraction of bottleneck 20 axisymmetricly.

Light source 1 is conventional LED, laser lighting lamp etc., and the light source lighted as single side face, the light source is placed in optically focused bottle 2 bottom centre, as shown in Fig. 3, Fig. 4, Fig. 5 and Figure 10；If the light source is spot light, the light source is arranged on the axis of symmetry, And a little set close to bottom of bottle, as shown in figure 13.

According to concrete application field and use requirement come specific design optically focused bottle size, major technique Con trolling index is irradiation Distance, irradiation area size and optically focused bottle bottle length, it is however generally that, irradiation distance and beam angle a sizes are inversely. The beam angle a that irradiation distance is short, light hole 21 is projected is big, and the body of optically focused bottle 2 is more thick fat, is such as used as and closely illuminates The desk lamp of device, indoor illumination application, as shown in figs. 4 and 7；Irradiation distance is remote, the projecting beam angle a of light hole 21 is small, Optically focused 2 bodies of bottle are elongated, vehicle-meeting lamp that can be as long distance illumination device, searchlight application, as shown in Fig. 6 and Fig. 9；And Shown in Fig. 5 and Fig. 8 is the middle transition product type between above two.

, can to increase illuminating effect if the light intensity of single light-gathering luminous and lighting device can not meet actual illumination needs It is a branch of so that multiple light-gathering luminous and lighting device to be combined as, constitute the anti-dazzle lighting device of high light intensity.

Shown in Fig. 2 is the present patent application technical scheme anti-glare schematic diagram.The anti-dazzle effect of the present patent application is main Surface is at two aspects：One is optically focused bottle structure, and light source and reflective inner surface are enclosed in bottle, can only pass through the logical of bottleneck 20 Unthreaded hole 21 sees that light, i.e. the technical program are can't see outside light source, beam angle effectively controls illumination range, positioned at illumination It will not be disturbed outside region by a veiling glare；Two be the light for the size of light hole 21 that bottleneck 20 is can only see by outside, Far smaller than existing reflector openings of sizes, thus will not produce and dazzle the eyes sense.
