Embodiment 1
As Figure 1-Figure 4, a kind of reflecting element 100 provided in an embodiment of the present invention, the reflecting element 100 include anti-
Portion 110 is penetrated, when incident light 200 is radiated on reflecting part 110, the reflecting part 110 can be by incident light 200 to circumferential reflection.
The reflecting part 110 includes the reflection conical surface 111 and the plane of reflection 112,112 edge of the reflection conical surface 111 and the plane of reflection
The axis direction of the reflection conical surface 111 is set gradually, when axis direction incidence of the incident light 200 along the reflection conical surface 111, and
The part light of reflected light can be radiated on the reflection conical surface 111, and the reflection conical surface 111 can be in the reflecting element 100
Circumferential to form cricoid Line of light 210, Line of light 210 forms straight line when being incident upon on metope；The part light of incident light 200
It can be radiated on the plane of reflection 112, the plane of reflection 112 can reflect the portions incident to the circumferential direction of reflecting element 100
Light 200, the light projection after reflection form a luminous point when on metope.It can use a branch of incidence by above-mentioned optical element
Light 200 is formed simultaneously 360 ° of ring lights and dotted light 220, and dotted light 220 plays the role of instruction to 360 ° of ring lights, and level turns
When the dynamic straight line laser mould group with reflecting element 100,360 ° of ring light does not change, and dotted light 220 will occur
It moves horizontally, to have the function that dynamic instruction.
Using the straight line laser mould group formed with above-mentioned reflecting element 100 360 ° of Line of light can be projected to side simultaneously
210 and 220,360 ° of Line of light 210 of dotted light a horizontal line can be indicated on metope, then dotted light 220 can position
