And light source is 1.5m or more by the preferable distance for being radiated at external receiving plane after lenticular unit.
It is 15 ° -55 ° that hot spot, which requires the beam angle realized,.
The light efficiency damage control: light efficiency=original light efficiency (simple lens) X85% loses 12%~15%.
The hot spot obtained using this lenticular unit is uniform, no layering, no macula lutea.
The radian of the periphery wall 23 of collector lens 2 between 20 ° -90 °, so as to there is preferable spotlight effect.
The bottom surface 52 of groove 5 be it is arc-shaped, some light is refracted to the periphery of collector lens by the internal perisporium of groove 5
Wall, and the lesser light of deflecting angle is then directly over the bottom surface of groove 5, arc-shaped bottom surface is directly condensed to outgoing end face 22,
Optically focused is carried out again, is guaranteed that light is effectively controlled in all directions, is improved light efficiency.
Further, the outgoing end face 22 of collector lens has the structure of a variety of further optically focused, as first embodiment,
As shown in Figure 5-Figure 7, the outgoing end face 22 of collector lens 2 is cone cell curved surface, and the outgoing end face 22 of collector lens 2 is from middle part to week
It encloses and (is tilted upward as shown in Figure 1) towards the inclination of incident end face direction, so that light be allowed to intersect maximum point and the normal (center of circle
Axis) direction is at 7.5 ° of -27.5 ° of injections, to reach preferable spotlight effect.
As second embodiment, as shown in figs 2-4, the outgoing end face 22 of collector lens 2 is Fresnel structure face, and

In ceiling, the light of sending can enter room by light exit.Alternatively, it is also possible to be mounted on furniture or household electrical appliance,
On shelf, cabinet, refrigerator, mirror cabinet, smoke exhaust ventilator, chandelier, floor lamp or desk lamp.
Further, it at the marginal position of shrinkage hole 4, can be provided in the one side that shrinkage hole deviates from light source tubaeform
Inclined surface, and the edge of shrinkage hole 4 forms sharp shape.
Shrinkage hole 4, which is configured to the tangent line on the face away from the one side of light source, to be emitted by the light of focusing optics
Face, it is therefore prevented that the light that light exit surface issues, such as scattering light are fallen on the side, 4 side of shrinkage hole forms sharp shape and falls
Angle enables and is suspended on the edge of shrinkage hole 4 by the light projected.
On the cross section perpendicular to incident end face 21, shrinkage hole 4 also can have recessed profile, the side of shrinkage hole 4
Can be straight line can also be preferably so that curvature towards collector lens or right with uniform or circular bend or parabolic curved
Light emitting direction becomes strong.For example, being radiated vertically downward if pedestal 1 is ceiling mounted, the curvature of the side of shrinkage hole 4
Radius can gradually become smaller towards upper end or become larger towards bottom.If the side of the profile of light in this way, can hinder
Hinder further radiating into inside for stray light.
For a good protection, pedestal can have in radiation direction to be extended, and forms tubular, which can be
Shrink the about a quarter of bore dia in the range of 4/4ths or the axial spacing of bore edges and Focused Optical system four
In the range of 4/1 mono- to four.
Additionally, the diameter of collector lens is made to be greater than or equal to lamps and lanterns by the size that the bore edges bore dia of lamps and lanterns limits
Bore dia, it is therefore preferable to two to three times of bore dia.
, can also be integrally formed since barn door can be seperated connection with pedestal, it shrinks the punching of bore dia barn door and comes
It limits, or is limited by the diameter of pedestal opening, the region that light beam is bordered on convergence intersection region can be slightly larger than shrinkage hole
Diameter, this structure can shorten the length of pedestal, and also can be realized good dazzle protection.
Pedestal can be sleeve shaped, the bottom margin at the edge of the side surface adjacent bores and have at least about two sides
Surface is also possible to cylindrical or sleeve-shaped, and side of base is also possible to the cover board of protuberance or protrusion, so as to lamps and lanterns
Global shape be spherical or egg type method.
Further, the internal diameter of base interior matches with the diameter of collector lens as far as possible, and the wall thickness of pedestal is small as far as possible, from
And the volume of entire lamps and lanterns can be reduced.
Collector lens 2 can also be directly integrally formed with light source, for example, light source, which directly emits and focuses out, meets above-mentioned spy
The light of point.Additionally, lighting device can also be set after light source emits beam, then light is projected to collector lens by lighting device
2, by lamps and lanterns issue all light and dished out by the light-emitting window with shrinkage hole.
As shown in Fig. 8-Figure 14, pedestal 1 can be made tubular or spherical shape or elliposoidal, be internally provided with cavity, light
Source and collector lens are arranged in cavity, in cavity, are provided with shrinkage hole and can be arc towards the one side of collector lens
