Detailed description of the invention
By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained below in conjunction with embodiment.
The design of the utility model most critical is: the combining structure adopting striped lens and convex cup lens, the scattered beam sent by light source is by the total reflection of striped lens outside wall surface and convex cup lens reflection, the light of lens outside wall surface total reflection controls final lens rising angle by striated surface, make reverberation and refract light project object on the surface simultaneously, the utilization rate of source light can be improved.
Please refer to Fig. 3 to Fig. 6, a kind of directed striped lens, comprise striped lens 1 and convex cup lens 2, the shape of described striped lens 1 is conical, radially opens outward along striped lens 1 is provided with breach, described convex cup lens 2 are positioned at gap position and are fixed on the bottom of striped lens 1, surround the groove position 5 of accommodating light source bottom the internal face of described convex cup lens 2 and striped lens 1; The top of described striped lens 1 is provided with boss 11, described boss 11 is provided with the different striped of multiple density 13, and described striped lens 1 sidewall is fully reflecting surface 12; Along convex cup lens 2 outer wall top, top-direction is provided with convex surface 21.
From foregoing description, the beneficial effects of the utility model are: the combining structure adopting striped lens 1 and convex cup lens 2, the astigmatism of light source irradiation, a part of light scioptics outer wall surface produces total reflection and projects fixed-direction, reach need projection set the goal on thing 4; Another part light scioptics outer wall surface is totally reflected on lens stripe surface, changes distribution of light through stripe surface, and what project needs sets the goal on thing 4; Last part light produces refract light by convex cup face and directly projects illuminated object surface, can source light set the goal on thing 4 with high angle cover by asymmetric setting of multiple curved surfaces of this surface of emission, thus improve the utilization rate of light efficiency, greatly can increase the uniformity of intensity of illumination and light, in addition, this structural design can meet multiple light source be identical angle arrangement reflection wash light effect.
