Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment 1
A kind of light source apparatus for shaping, including light source 1, plano-convex spherical lens 2, shaping device 3 and globoidal mirror 4, the shaping
Device 3 is located at the side of light source 1 and plano-convex spherical lens 2 between light source 1 and shaping device 3, and globoidal mirror 4 is located at shaping
Side of the device 3 far from plano-convex spherical lens 2.Shaping device 3 includes entering light face 31 and light-emitting surface 32, and axial ray is leaned in entering light face 31
Place be concave surface, negative cruvature gradually tends to 0 as diameter increases directional curvature within the scope of light passing, become after reaching 0 just and by
It is cumulative to add；Light-emitting surface 32 by axial ray place be concave surface, negative cruvature, and curvature relative to entering light face closer to 0, in light passing model
Gradually tend to 0 as diameter increases directional curvature in enclosing, becomes after reaching 0 just and gradually increase.Entering light face 31 and light-emitting surface 32 are equal
For rotational symmetric aspheric, and entering light face 31 and the rotation axes of symmetry of light-emitting surface 32 are coaxial.Plano-convex spherical lens 2 and globoidal mirror 4
It is all made of K class, ZK class, F class, ZF class, door screen is any one production in the optical glass of the trade mark.
Embodiment 2
A kind of light source apparatus for shaping, including light source 1, plano-convex spherical lens 2, shaping device 3 and globoidal mirror 4, the shaping
Device 3 is located at the side of light source 1 and plano-convex spherical lens 2 between light source 1 and shaping device 3, and globoidal mirror 4 is located at shaping
Side of the device 3 far from plano-convex spherical lens 2.Plano-convex spherical lens 2 and light source 1 are the arrangement of uniline multiple row.On globoidal mirror 4
It is even that cambered surface mirror unit 5 is distributed with, it can be flat to focusing by the light projection for being incident in the cambered surface mirror unit 5 being emitted from focusing block
Hot spot 6 corresponding with the cambered surface mirror unit 5 is formed on face.The surface of plano-convex spherical lens 2 and globoidal mirror 4 is coated with anti-reflection film,
Translucency can be increased, improve optical energy utilization efficiency.
The working principle of the utility model is: light source issues wide-angle light beam, by plano-convex spherical lens 2 and shaping device
3, the direction negative cruvature diffusing light of axial ray is leaned in shaping device 3, as 1 light-emitting angle off-axis angle of light source is got over
Corresponding aspherical diameter is also bigger when greatly, into shaping device 3, and curvature gradually turns negative number to positive number, and switchs to convex surface by concave surface, this
The light that sample light is just formed close to optical axis is dissipated, and the big angle of emergence light far from optical axis is converged, thus greatly improve
It is emitted the light energy of angular direction, forms wide-angle, large-scale Uniform Illumination, then passes through globoidal mirror 4, on globoidal mirror 4
Cambered surface mirror unit 5 reflects and forms light, dissipates again after convergence of rays, and sub-light spot is formed on focussing plane.
Each cambered surface mirror unit 5 forms respective sub-light spot, and the shape of these sub-light spots is all identical, and has same
One center, therefore these sub-light spots overlap, and together constitute the hot spot 6 on focussing plane.
The distance between plano-convex spherical lens 2, shaping device 3 and globoidal mirror 4 and size determine the size of hot spot.
It should be strongly noted that passing through plano-convex spherical lens 2, shaping device 3, globoidal mirror 4 and globoidal mirror in the application
It is not high with optical energy utilization efficiency to efficiently solve the problems, such as that 6 size of hot spot is not adjustable for the cooperation of unit 5.
