It is mutually perpendicular in the first reflecting surface 135 and the second reflecting surface 136, in the case that side wall 130 is totally reflected, for reflection
Light path trend in device 100 is specifically described：
With reference to shown in Fig. 2 to Fig. 6, the light portion that luminescence component 2 is sent enters the first lens from upper incidence surface 123 collimation
12, directly from the light extraction of outer surface 122 after the refraction of the first lens 12, from the outgoing of light-emitting window 14, partly enter from side incidence surface 124
Enter the first lens 12, from the light extraction of outer surface 122 after the refraction of the first lens 12, incide inner surface 131, it is anti-through side wall 130
Again from the outgoing of light-emitting window 14 after penetrating.Light is specially in the internal reflection of side wall 130, its light path：Light is incident to outer by inner surface 131
The a points of the first reflecting surface 135 on surface 132, and the b points of the second reflecting surface 136 are totally reflected to, it is complete through the second reflecting surface 136
Reflection returns to inner surface 131, is outwards projected by light-emitting window 14 after the outgoing of inner surface 131.As shown in figure 4, for single sawtooth
Structure 134, from the point of view of overlook direction, when light is mapped to a points on the first reflecting surface 135, can be reflexed to by total reflection principle
The b points of second reflecting surface 136, then gone out by the b point reflections of the second reflecting surface 136, last emergent ray meets with incident ray
It is totally reflected angular relationship.It is totally reflected it is understood that to be realized in lens interior, the incidence angle between light and reflecting surface must be sufficient
Enough big, otherwise light will be transmitted away, and this angle can be different according to the material of lens.We can be with from Fig. 5
See, if it is parallel with incidence surface to be not located at the broached-tooth design of exiting surface, i.e. exiting surface, then when light reaches reflecting surface
Incidence angle is 0 °, and can not so be totally reflected to transmit, and adds a points that light after broached-tooth design reaches the first reflecting surface 135
When, incident angle is 45 ° and is more than critical angle therefore can realize total reflection.When luminescence unit 22 is located at the center of light source board 21
When, because reflection unit 10 is axle rotational symmetry structure in the present embodiment, its light sent is for each position on inner surface 131
Put, from horizontal direction from the point of view of be all perpendicular to inner surface 131, as it was previously stated, reaching the first reflecting surface 135 and the second reflection
All total reflection can be achieved for 45 ° in incidence angle during face 136.But when luminescence unit 22 is multiple, it can be arranged on light source board 21
Cloth has certain glancing incidence angle α into the light-emitting area with certain area, therefore when inciding inner surface 1311, and now light
When reaching the first reflecting surface 135 of broached-tooth design 134 again through superrefraction, incidence angle is changed into 45 ° and subtracts α1, incident angle diminishes
So that the realization of total reflection can not be ensured, therefore we should avoid the appearance of such case as far as possible, and luminescence unit 22 is concentrated
The central area of light source board 21 is arranged on, to cause glancing incidence angle α1It is small as far as possible.For incident angle α1Scope, it is different
The lens that are made of material, its admissible glancing incidence angle α1Scope is different, for the lens being made with PMMA, its α1≤
4.4 °, for the lens being made with PC, its α1≤9.5°.Because broached-tooth design is right angle faceted pebble in the present embodiment, thus go out
Firing angle α2Equal to glancing incidence angle α1.In the structure of on-right angle faceted pebble, angle of emergence α2Relative to incident angle α1Can change and
Form different light efficiencies.
