Light reflex to the side wall of lens body 101.
Collimation portion 1 is used to the light that light source 200 issues becoming directional light, in order to control the transmission path of light.By standard
After straight portion 1 collimates, the light of the first reflecting surface of directive 2 is roughly parallel to the axis of lens body 101.
In one embodiment, as Figure 1-Figure 4, collimation portion 1 includes the light source holding tank 11 of annular.Light source accommodates
Slot 11 includes the concave surface 12 positioned at upper end, the side wall 13 positioned at 12 side of concave surface.Light by concave surface 12 becomes directional light.Concave surface
12 rotate for camber line around 101 center of lens body (middle part that 101 center of lens body is located at the horizontal cross-section of lens body 101)
Made of the surfaces of revolution, wherein in the horizontal direction (direction vertical with 101 axis of lens body), camber line is far from lens body 101
Center, i.e., in the horizontal direction, the first end of camber line (close to the one end at 101 center of lens body) and 101 center of lens body it
Between there are spacing.Camber line can be circular arc line or oval camber line.Spacing between 101 center of camber line first end and lens body can
To set according to demand.The length of camber line can be set according to 200 size of light source.
The light source 200 that light source holding tank 11 is arranged in can be LED (Light Emitting Diode, light emitting diode)
Light source 200.Multiple LED light sources 200 are arranged in interval in light source holding tank 11, and multiple LED light sources 200 are around lens body 101
Center annular arrangement, and the center of each LED light source 200 is located at the center of camber line.
It is arranged through the above way, on the basis of guaranteeing convenient for control light, light source 200 can be made to arrange more dispersed, made
Heat dissipation effect is preferable, and can guarantee the power of illuminator.
Side wall 13 includes the lateral wall 132 positioned at the inner sidewall 131 of 12 inside of concave surface and positioned at 12 outside of concave surface at this time.It is interior
