As shown in Figures 2 to 5, reflection unit 5a is using lens as reflecting wall 50a, and in a ring and thickness is uniform, reflection
Wall 50a surrounds an optical space 501a.Such structure is similar to existing reflector, and only material uses transparent material, outside
It sees penetrating, and is easy to be replaced with existing reflector.Specifically, reflection unit 5a has inner surface 51a, outer surface
52a, first end face 53a, second end face 54a, reflection unit 5a light inlet 55a be located at first end face 53a, light-emitting window 56a
It is connected in second end face 54a, light inlet 55a and light-emitting window 56a with optical space 50a, light source board 31a closes light inlet 55a.It is interior
Surface 51a wall surface is smooth, is the incidence surface of reflection unit 5a, and is simultaneously also the light-emitting surface of reflection unit 5a.Outer surface 52a packet
Include several continuously arranged broached-tooth design 520a.Each broached-tooth design 520a includes the first reflecting surface 521a and the second reflecting surface
522a, the first reflecting surface 521a and the second reflecting surface 522a are mutually perpendicular to, and are intersected with crest line, which can be straight line
It can be camber line.The both ends of each broached-tooth design 520a extend respectively to first end face 53a and second end face 54a, so that light
It can be totally reflected when being incident upon reflecting wall 50a.In other embodiments, the first reflecting surface 521a and the second reflecting surface 522a
Angle can not also be in 90 °, it can be less than or greater than 90 °, the folder of the light efficiency of reflection unit 5a in broached-tooth design 520a
Angle is best in the case where being 90 °, and mirror surface total reflection can occur along incident light direction for emergent light.The angle of broached-tooth design 520a is less than
Or it is greater than 90 °, the angle of emergence made of all changing former bus and can reflecting reduces light efficiency.
In the present embodiment, the diameter of light inlet 55a is less than the diameter of light-emitting window 56a, in other interchangeable embodiment party
In formula, the diameter of light inlet 55a can also be equal to the diameter of light-emitting window 56a, i.e. reflection unit 5a is straight-tube shape.The reflection unit
5a is made into integration by transparent plastic or glass material, and wherein PMMA, PC etc. can be selected in plastic material.The thickness of reflection unit 5a is most
It is thin to can be made into 2 millimeters (mm), therefore, when the structure size of reflection unit 5a is very big, material cost and molding difficulty can be saved.
In addition, it is necessary to which explanation, can be in reflection unit the problem of due to machining accuracy in mold design or molding
Fillet is formed at the intersection of the first reflecting surface 521a and the second reflecting surface 522a of 5a, be incident on light on fillet will reflect and
Stray light is formed out, and fillet is bigger, and central light strength is smaller, and stray light is more, but existing machining accuracy is formed by fillet pair
Total light efficiency, the beam angle of reflection unit 5a influences less, therefore we are believed that reflection unit 5a is a total reflection lens.
It emits beam below for luminescence unit 32a and moves towards to carry out into the light after the inner surface 51a of reflection unit 5a
It illustrates.
In conjunction with shown in Fig. 4 to Fig. 8, the light that luminescence unit 32a is issued enters from light inlet 55a, and part is directly from light out
Mouth 56a is projected after being emitted to optical element 2a, is partially emitted again from light-emitting window 56a after reflection unit 5a reflection, finally by light
Element 2a is learned to project.It is reflected on broached-tooth design 520a, optical path specifically: light is incident to outer surface 52a by inner surface 51a
On the first reflecting surface 521a a point, and be totally reflected to the b point of the second reflecting surface 522a, be totally reflected through the second reflecting surface 522a
Inner surface 51a is returned, enters optical space 50a after inner surface 51a refraction, then projected outward by light-emitting window 56a, finally by light
Learn element 2a outgoing.As shown in fig. 7, for single broached-tooth design 520a, from the point of view of overlook direction, when light is mapped to the first reflection
When a point on the 521a of face, the b point of the second reflecting surface 522a, then the b by the second reflecting surface 522a can be reflected by total reflection principle
Point reflection and go out, last emergent ray and incident ray meet total reflection angular relationship.It is understood that be realized in lens interior
Total reflection, the incidence angle between light and reflecting surface must be sufficiently large, and otherwise light will transmit away, this angle can basis
The material of lens and it is different.It will be seen that going out if being not located at the broached-tooth design of light-emitting surface from Fig. 7
Smooth surface is parallel with incidence surface, then incidence angle is 0 ° when light reaches reflecting surface, can not be totally reflected can only transmit in this way, joined
When light reaches a point of the first reflecting surface 521 after broached-tooth design, incident angle is greater than critical angle therefore can realize for 45 ° to be all-trans
It penetrates.It is circular, hair by reflection unit 5a in this present embodiment when luminescence unit 32a is located at the center of light inlet
Light unit 32a should be located at center location, issue light for each position on inner surface 51a, from horizontal direction from the point of view of
All be perpendicular to inner surface 51a, as previously mentioned, when reaching outer surface 52a and the incidence angle of reflecting surface be all 45 ° can be achieved
Total reflection.But in conjunction with shown in Fig. 2 and Fig. 8, since luminescence unit 32a is the light-emitting surface with certain area, it is incident on
There is certain light source incidence angle α when incidence surface 51a1, and light reaches the first anti-of broached-tooth design 520a through superrefraction again at this time
When penetrating face, incidence angle becomes 45 ° and subtracts α1, incident angle becomes smaller so that not can guarantee the realization of total reflection, therefore we answer
This is avoided the appearance of such case as far as possible, by luminescence unit 32a concentrated setting in the central area of light inlet 55a, so that entering
Firing angle α1It is small as far as possible.For incident angle α1Range, lens made of different materials, admissible incident angle α1Model
Difference is enclosed, for lens made of PMMA, α1≤ 4.4 °, for lens made of PC, α1≤9.5°.Due at this
Broached-tooth design 520a is right angle faceted pebble, thus angle of emergence α in embodiment2Equal to incident angle α1.In the structure of on-right angle, outgoing
Angle α2Relative to incident angle α1It can change and form different light efficiencies.
