Think one, or multiple.
As shown in Figures 2 and 3, reflecting wall of the lens 1 as reflection unit 10, its in a ring, and thickness is uniform, lens 1
Surround optical space.Such structure employs transparent material similar to existing reflector, simply material, and outward appearance is penetrating, and easily
It is replaced in existing reflector.Specifically, the lens 1 have inner surface 11, outer surface 12, first end face 13, second
End face 14, the light inlet 15 of reflection unit are located at the first end face 13 of lens 1, and light-emitting window 16 is located at the second end face 14 of lens 1,
Light inlet 16 and light-emitting window 17 connect with optical space, and light source board 21 closes light inlet 15.The wall of inner surface 11 is smooth, is lens
1 incidence surface, and be also the exiting surface of lens 1 simultaneously.Outer surface 12 is provided with some continuously arranged broached-tooth designs 120.Often
Individual broached-tooth design 120 includes the first reflecting surface 121 and the second reflecting surface 122, the first reflecting surface 121 and the phase of the second reflecting surface 122
It is mutually vertical, and it is intersecting there is crest line, the crest line can be that straight line can also be camber line.The both ends difference of each broached-tooth design 120
Extend to first end face 13 and second end face 14 so that can be totally reflected when light is incident upon the reflecting wall.In other embodiment party
In formula, the angle of the first reflecting surface 121 and the second reflecting surface 122 can not also be in 90 °, you can with less than or greater than 90 °, still
The light efficiency of the reflection unit is optimal in the case where angle is 90 °, and total reflection can be achieved.In the present embodiment, light inlet 15
Diameter is less than the diameter of light-emitting window 16, and in other interchangeable embodiments, the diameter of light inlet 15 can also be equal to light extraction
The diameter of mouth 16, i.e. lens 1 are straight-tube shape.The lens 1 are made into integration by transparent plastic or glass material, and wherein plastic material can
From PMMA, PC etc..The thickness of lens 1 is most thin to can be made into 2 millimeters (mm), therefore, can be with when the physical dimension of lens 1 is very big

,, can be the of lens 1 the problem of due to machining accuracy in mold design or shaping in addition, it is necessary to explanation
At the intersection of one reflecting surface 121 and the second reflecting surface 122 formed fillet, incide the light on fillet refraction is gone out to be formed it is miscellaneous
Astigmatism, but fillet influences less on total light efficiency, the beam angle of lens 1, therefore we are believed that lens 1 are saturating for a total reflection
Mirror.
Emit beam below for luminescence component 2 and be specifically described into the light trend after inner surface 11.
With reference to shown in Fig. 3 to Fig. 6, the light that luminescence component 2 is sent enters from light inlet 15, and part is directly from light-emitting window 16
Outgoing, partly it is emitted again from light-emitting window 16 after the reflection of lens 1.Reflected on broached-tooth design 120, its light path is specially：Light
The a points for the first reflecting surface 121 being incident to by inner surface 11 on outer surface 12, and the b points of the second reflecting surface 122 are totally reflected to,
It is totally reflected through the second reflecting surface 122 and returns to inner surface 11, enters optical space after the refraction of inner surface 11, finally by light-emitting window 16
Outwards project.As shown in figure 5, for single broached-tooth design 120, from the point of view of overlook direction, when light is mapped to the first reflecting surface 121
On a points when, can reflex to the b points of the second reflecting surface 122 by total reflection principle, then by the b point reflections of the second reflecting surface 122 and
Go out, last emergent ray meets total reflection angular relationship with incident ray.It is totally reflected it is understood that to be realized in lens interior, light
Incidence angle between line and reflecting surface must be sufficiently large, and otherwise light will transmit away, and this angle can be according to the material of lens
Matter and it is different.If it will be seen that being not located at the broached-tooth design of exiting surface from Fig. 5, i.e., exiting surface and enter
Smooth surface is parallel, then incidence angle is 0 ° when light reaches reflecting surface, and can not so be totally reflected to transmit, and add broached-tooth design
When light reaches a points of the first reflecting surface 121 afterwards, incident angle is 45 ° and is more than critical angle therefore can realize total reflection.When luminous
When unit 22 is located at the center of light inlet, because reflection unit 10 is circular in the present embodiment, luminescence unit 22 should
Should be located at home position, its light sent for each position on inner surface 11, from horizontal direction from the point of view of be all perpendicular to it is interior
Surface 11, as it was previously stated, when reaching outer surface 12 and reflecting surface incidence angle all for 45 ° can be achieved total reflection.But tie
Close shown in Fig. 1 and Fig. 6, because luminescence unit 22 is arranged into the light-emitting area with certain area to be multiple in light source board 21, therefore
There is certain light source incidence angle α when inciding incidence surface 111, and now light reaches the of broached-tooth design 120 through superrefraction again
During one reflecting surface, incidence angle is changed into 45 ° and subtracts α1, incident angle diminish so that can not ensure total reflection realization, therefore I
Should avoid the appearance of such case as far as possible, by the concentrated setting of luminescence unit 22 in the central area of light inlet 15, to cause
Incident angle α1It is small as far as possible.For incident angle α1Scope, lens made of different materials, its admissible incident angle α1
Scope is different, for lens made of PMMA, its α1≤ 4.4 °, for lens made of PC, its α1≤9.5°.Due to
Broached-tooth design is right angle faceted pebble in the present embodiment, thus angle of emergence α2Equal to incident angle α1.In the structure of on-right angle, the angle of emergence
α2Relative to incident angle α1It can change and form different light efficiencies.
In summary, the light source module group that the utility model embodiment provides, using lens as a kind of reflection unit, its appearance
Face includes multiple broached-tooth designs continuously arranged, and inner surface is used as incidence surface and exiting surface simultaneously, and outer surface includes the first reflection
Face and the second reflecting surface, it is designed so that and can be emitted by the incident light of inner surface with the optical effect of total reflection, not
