Abstract
The utility model belongs to the technical field of luminaries and relates to a multi-virtual-image hierarchical light-emitting lamp which comprises a housing, a shade, a mirror, a lens, a circuit board and LED sources. The mirror, the lens, the circuit board and the LED sources are disposed inside the housing. The shade is disposed at the front end of the housing. The front of the lens is provided with distribution pattern. The mirror is disposed on the lens and is close to the shade. The circuit board is disposed on the back of the lens. The LED sources are arranged on the circuit board and correspond to a rear incidence hole of the lens. The inner side of the shade is aluminized. The outer surface of the mirror is polished and aluminized. When the lamp operates, the light from the LED sources irradiates to the shade through the distribution pattern of the lens, part of the light passes the shade to form real images of the light sources, and the other part of the light is reflected back to the mirror. The free-form surface of the mirror coordinates with the free-form surface of the shade so that image size and depth are controllable.
Description
Technical field
The utility model belongs to lighting device manufacturing technology field, relates to a kind of lamp of automobile.
Background technology
Existing car light as position lamp, Brake lamp and steering indicating light, generally adopts common bulb as light source, and power consumption is larger, and light is not soft, and is fragile.More advanced car light adopts LED as light source, although save electric quantity consumption, and long service life, the light ratio that generates is more stiff.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of many virtual images hierarchical light-emitting lamp of light grace.
the scheme of technical solution problem of the present invention is to adopt housing, face shield, speculum, lens, wiring board and LED light source consist of many virtual images hierarchical light-emitting lamp, speculum, lens, wiring board and LED light source are contained in housing, face shield is arranged on the housing front end, lens is made by the PMMA transparent material, there is the luminous intensity distribution decorative pattern in the front, speculum is arranged on lens, speculum is near face shield, wiring board is in the lens back, be placed with LED light source on wiring board, LED light source is corresponding with lens rear portion light inlet, face shield is made by colourless transparent material, aluminize in the inboard, transmitance is controlled between 70%--80%, the polishing of speculum outer surface is aluminized.During work, the light that LED light source sends is radiated on face shield by the luminous intensity distribution decorative pattern of lens, wherein a part of light transmission face shield outgoing, form the real image of light source, another part reflexes to again on speculum, two free form surfaces of speculum and face shield coordinate, take irregularly shaped light source or illuminator as benchmark, light Multi reflection between two free form surfaces that irregularly shaped light source or illuminator are sent, and utilize controlled half-reflection and half-transmission coating process to realize repeatedly imaging (virtual image), form the effect of spatial multi time sense.The design of free form surface, with in the space take the smooth free curve of node control degree of crook as the basis, coordinate optical principle, size, the depth of imaging are realized controlled, thereby are applied among light fixture.
Face shield and speculum are free form surface, are to be scanned by the two or more pieces SPL to form, and optical surface according to ray tracing method designing and calculating out.At first, base curve is changed into nurbs surface, according to grid vector and the weights of the control network of ray tracing modified result nurbs surface, complete optical design.
Nurbs surface vector and control of right formula are:
B wherein
i,jBe the control vertex of curved surface S (u, v), w
i,jBe corresponding control vertex B
i,jWeighted value (w
i,j0), in fact it defined the influence degree of each control vertex to curved surface S (u, v) shape, N
i,k(u) and N
j,l(v) be respectively and be defined in knot vector U=[u0, u1 ..., um+k+1] and V=v0, v1 ..., vn+l+1] on k time and l standard B spline base function.
The utlity model has following advantage:
1. realize three-dimensional illumination effect with the plane light source of arranging;
2. increase light source apparent surface area more than 3 times;
3. adapt to the various planar light sources effect of arranging;
4. because light source is the plane, its cost is lower than the light source cost with spatial arrangement.
