In the lightings such as canopy lamp, fresh lamp, outdoor lights.
Each element in light source module 100 for providing below for the embodiment of the present invention 1 and the connection between element are closed
It is to illustrate.
As shown in figure 1, luminescence component 2 includes light source board 21 and some luminescence units 22 on light source board 21.Specifically
, some luminescence units 22 are arranged along the length direction d2 of light source board 21, and are arranged on the middle part of light source board 21.In reality of the present invention
Apply in example 1, some luminescence units 22 can be arranged to a row or multi-row along the length direction d2 of light source board 21.Luminescence unit 22 can
Think LED luminescence unit.
As shown in Figures 1 and 3, lens 1 are used as the reflecting wall of reflection unit, and which is in tabular, and thickness is uniform, is arranged on
The both sides of the width d1 of light source board 21.In other embodiments, lens 1 can also be the tabular knot with certain radian
Structure.
Lens 1 are with inner surface 11, outer surface 12, first end face 13, second end face 14, the reflection positioned at first end face 13
The light inlet 16 of device, positioned at the light-emitting window 17 of the second end face 14 of lens 1, the diameter of light inlet 16 is straight less than light-emitting window 17
Footpath.In conjunction with shown in Fig. 2, inner surface 11 includes multiple broached-tooth designs 110 of parallel continuous arrangement, and each broached-tooth design 110 includes
Intersecting first refractive face 111 and the second plane of refraction 112, and the rib that first refractive face 111 and the second plane of refraction 112 are crossed to form
Line (is not indicated), and the two ends of each broached-tooth design 110 extend respectively to first end face 13 and second end face 14.In the present embodiment
In, it is mutually perpendicular between first refractive face 111 and the second plane of refraction 112, in other embodiments, 111 He of the first reflecting surface
The angle of the second reflecting surface 112 might be less that or more than 90 °, in the case that angle is 90 °, light efficiency is optimal.Specifically, thoroughly
The inner surface 11 of mirror 1 is incidence surface, while being also exiting surface.Outer surface 12 is hydraulically smooth surface, used as reflecting surface.The lens 1 are
Transparent configuration, is made into integration by plastics or glass material, and wherein plastic material can select PMMA, PC etc..
It is understood that total reflection will be realized in lens interior, the angle of incidence between light and reflecting surface must be sufficiently large, no
Then light will transmission go out, this angle can be different according to the material of lens.For making the light for injecting lens 1 can
It is totally reflected in outer surface 12, it is necessary to which the angle of light and outer surface 12 is planned, Fig. 6 is broached-tooth design level side
To index path it may be seen that light is substantially not enough to form total reflection in the incident angle of outer surface 12, institute here
Reflecting, the angle for also having in a vertical component is because, as shown in figure 3, with reference to the graphics of Fig. 5, working as level
Component and vertical component superposition angle of incidence are just sufficiently large, and therefore the angle of incidence of vertical direction have to be larger than certain angle ability
Realize total reflection.The angle of incidence of vertical direction is more than certain angle, that is, first refractive face 111 and the second plane of refraction 112
Forming angle α between the crest line being crossed to form and 21 place plane of light source board needs the specific angle A less than.We are with rib
The angle of line is illustrated, and whether the requirement through crest line incidence to angle is different to be primarily due to light, if light
Can reflect from first refractive face 111 or 112 incidence of the second plane of refraction, such light can increase in the angle of incidence of outer surface,
And if light is from crest line position incoming Level direction almost without angle, be most difficult to realize total reflection, therefore it is contemplated that being all-trans
The design for penetrating face is calculated with the light path of crest line position.The value of this A is related to the refractive index of lens 1, at this
In embodiment, from PC material, A is 38 °, if can be increased using the higher materials A of refractive index, is come with current common used material

Shape, the angle α of crest line and light source board place plane is a definite value, refer to Fig. 3.And when form of lens is different, such as
Shown in Fig. 4, when crest line is for camber line, on crest line, the angle α of the tangent line of every bit and light source board place plane should meet above
Restrictive condition, i.e. its value are less than A.So meeting angle α less than A (A is the corresponding angle of above-mentioned unlike material), the lens 1
Meet total reflection condition.Other do not need lens total reflection embodiments in, can without meet angle α less than A bar
Part, you can so that using arbitrary angle between 0-90 °, so a kind of semi-transparent semi-reflecting effect can be formed in outer surface 12.
In the present embodiment, the thickness of lens 1 can be made into 2 millimeters (mm) or thinner, and therefore, 1 physical dimension of lens is very big
When, material cost and molding difficulty can be saved.In addition, it is necessary to illustrate, in Design of Dies or molding, due to processing essence
The problem of degree, can form fillet at the intersection of the first refractive face 111 of lens 1 and the second plane of refraction 112, incide on fillet
Light refraction is gone out to form veiling glare, but fillet total light efficiency of lens, beam angle are affected little.

The light that luminescence component 2 sends is entered from light inlet 16, partly directly from 17 outgoing of light-emitting window, partly through lens 1
Again from 17 outgoing of light-emitting window after reflection.For the light path on broached-tooth design 110 referring specifically to shown in Fig. 5 and Fig. 6, light is incident on
On the inner surface 11 of lens 1, the first refractive face 111 through the broached-tooth design 110 on inner surface 11 is refracted to outer surface 12, through outer
Surface 12 is totally reflected to inner surface 11, by 17 outgoing of light-emitting window after reflecting through inner surface 11.Fig. 5 shows that a kind of light enters saw
Concrete trend in toothing 110.Specifically, light goes out be totally reflected to the second plane of refraction 12 of inner surface 11 through outer surface 12 after
Penetrate.What luminescence component 2 sent also has some light (not shown), reflexes to the first refractive face of inner surface 11 through outer surface 12
Outgoing after 111, or first refractive face 111 and 112 intersecting crest line of the second plane of refraction is reflexed to through outer surface 12, then go out
Penetrate.In conjunction with shown in Fig. 3, as long as crest line and the angle α of 22 place plane of light source board meet the corresponding angle model of above-mentioned different materials
Enclose, the light being incident on lens 1 can be totally reflected, by 11 outgoing of inner surface.
Connecting plate 15 is also that tabular, its both sides are fitted with the side of lens 1, and its lower surface is flushed with first end face 13,
Upper surface is flushed with second end face 14, is enclosed luminescence component 2 with this and is located at receiving space that lens 1 and connecting plate 15 constituted (not
Indicate) in, the light for being sent by luminescence component 2 carries out secondary light-distribution by lens 1 or connecting plate 15.The connecting plate 15 is towards going out light
The one side of mouth is fully reflecting surface, and in order to form fully reflecting surface, connecting plate 15 can be made up of the material with total reflection function, such as
Plastics, metal, it is also possible to realized by surface treatment, such as surface polishing, coating film treatment.

As shown in fig. 7, the embodiment of the present invention 2 provides a kind of light source module 100 ', which is included using lens 1 ' as reflection
The reflection unit 10 ' of wall and the luminescence component 2 ' of 1 ' one end of lens is arranged on, the light portion that luminescence component 2 ' sends is through saturating
The refraction of mirror 1 ', reflection, reflect again after by lens 1 ' the direct outgoing of inner surface 11 '.The light source module 100 ' can be applicable to
In the lightings such as Down lamp, shot-light, Ceiling light.
Each element in light source module 100 ' for providing below for the embodiment of the present invention 2 and the connection between element are closed
It is to illustrate.
As shown in Fig. 2 luminescence component 2 ' includes light source board 21 ' and the luminescence unit 22 ' being located on light source board 21 ', light
Unit 22 ' is arranged on the middle part of light source board 21 '.Can arrange a luminescence unit 22 ', it is also possible to multiple luminescence units of arranging
22’.
As shown in Figures 7 and 8, lens 1 ' are that a kind of reflection unit 10 ', which is in horn-like, and thickness is uniform.Such knot
Structure is similar to existing reflector, and simply material employs transparent material, and outward appearance is penetrating, and is easy to be replaced with existing reflector
Change.Specifically, the lens 1 ' are with inner surface 11 ', outer surface 12 ', first end face 13 ', second end face 14 ', positioned at first end
The light inlet 16 ' in face 13 ' and the light-emitting window 17 ' positioned at second end face 14 ', the diameter of light inlet 16 ' is straight less than light-emitting window 17 '
Footpath.Inner surface 11 ' is made up of the continuous broached-tooth design 110 ' of a circle, and each broached-tooth design 110 ' includes intersecting first refractive face
111 ' and second plane of refraction 112 ', and the crest line (sign) that first refractive face 111 ' and the second plane of refraction 112 ' are crossed to form,
The two ends of each broached-tooth design 110 ' extend respectively to first end face 13 ' and second end face 14 '.In the present embodiment, lens 1 '
For rotational symmetry structure, the crest line that first refractive face 111 ' and the second plane of refraction 112 ' are crossed to form is straight line, and first refractive
It is mutually perpendicular to, in other embodiments, first refractive face 111 ' and the second refraction between face 111 ' and the second plane of refraction 112 '
The crest line being crossed to form between face 112 ' is alternatively camber line, and the angle of first refractive face 111 ' and the second plane of refraction 112 ' also may be used

Become, wherein plastic material can select PMMA, PC etc..
It is understood that total reflection will be realized in lens interior, the angle of incidence between light and reflecting surface must be sufficiently large, no
Then light will transmission go out, this angle can be different according to the material of lens.For making the light for injecting lens 1 ' all
Can be totally reflected in outer surface 12 ', it is necessary to which the angle of light and outer surface 12 ' is planned, Figure 10 is broached-tooth design
The index path of horizontal direction it may be seen that light is substantially not enough to form total reflection in the incident angle of outer surface 12 ',
Here why can reflect, be because the angle for also having in a vertical component, as shown in Figure 8,9, such horizontal component
Just sufficiently large with vertical component superposition angle of incidence, therefore the angle of incidence of vertical direction have to be larger than certain angle and could realize
Total reflection.The angle of incidence of vertical direction is more than certain angle, that is, first refractive face 111 ' and 112 ' phase of the second plane of refraction
Hand between the crest line for being formed and 21 ' place plane of light source board and form angle α ' the specific angle A less than is needed, if light
Can reflect from first refractive face 111 ' or the 112 ' incidence of the second plane of refraction, such light can increase in the angle of incidence of outer surface
Greatly, and if light is from crest line position incoming Level direction almost without angle, it is most difficult to realize total reflection, therefore it is contemplated that whole
The design of 1 ' fully reflecting surface of individual lens is all the value for calculating A with the light path of crest line position.This angle α ' and lens 1 '
Refractive index correlation, in the present embodiment, from PC material, A is 38 °, if can be 40 ° using the higher materials A of refractive index,
When from PMMA, A is 30 °.For the light source module 100 ' of the present embodiment, each broached-tooth design 110 ' due to lens 1 ' is
Vertical bar shape, so the angle α of crest line and light source board place plane ' it is a definite value, when crest line is for camber line, every bit on crest line
Tangent line and light source board place plane angle α ' restrictive condition, i.e. its value above should be met less than A.So meeting angle
α ' is less than the corresponding angle A of above-mentioned unlike material (A is the corresponding angle of above-mentioned unlike material), and the lens 1 ' meet total reflection bar
Part.Other do not need lens total reflection embodiments in, can without meet angle α less than A condition, you can with adopt
Arbitrary angle between 0-90 °, so can form a kind of semi-transparent semi-reflecting effect in outer surface 12.
In the present embodiment, the thickness of lens 1 ' is most thin to can be made into 2 millimeters (mm), therefore, when 1 ' physical dimension of lens is very big,
Material cost and molding difficulty can be saved.In addition, it is necessary to illustrate, in Design of Dies or molding, due to machining accuracy
Problem, can at the intersection of the first refractive face 111 ' of lens 1 ' and the second plane of refraction 112 ' formation fillet, incide fillet
On light refraction is gone out to form veiling glare, but fillet affects little on the overall light efficiency of lens, beam angle, and therefore we are also
It is it is considered that this is the reflection unit of a total reflection.
The light trend for entering after broached-tooth design 110 ' that emits beam below for luminescence component 2 ' is specifically described.
Enter from light inlet 16 ' in conjunction with the light that shown in Fig. 8 to Figure 10, luminescence component 2 ' sends, part is directly from going out light
