Abstract
The invention discloses a multi-virtual image laminating type light emitting lamp, which belongs to the technical field of manufacturing an illuminating device. The multi-virtual image laminating type light emitting lamp is formed by adopting a shell, a mask, a reflection mirror, a light distribution mirror, a circuit board and an LED (Light Emitting Diode) light source, wherein the reflection mirror, the light distribution mirror, the circuit board and the LED light source are arranged in the shell, the mask is arranged at the front end of the mask, the front surface of the light distribution mirror is provided with light distribution patterns, the reflection mirror is arranged on the light distribution mirror and is close to the mask, the circuit board is arranged on the rear surface of the light distribution mirror, the LED light source is distributed on the circuit board, the LED light source corresponds to a light inlet at the rear part of the light distribution mirror, the inner side of the mask is plated with aluminum, and the outer surface of the reflection mirror is polished and plated with the aluminum. When the multi-virtual image laminating type light emitting lamp disclosed by the invention is in work, light emitted from the LED light source can irradiate on the mask through the light distribution patterns of the light distribution mirror, one part of the light can irradiate outwards by penetrating through the mask, thus a real image of the light source can be formed, the other part of the light can be reflected to the reflection mirror, two free curved surfaces of the reflection mirror and the mask can be matched, and thus the controllability of the size and the depth of an image can be realized.
Description
Technical field
The invention belongs to lighting device manufacturing technology field, relate to a kind of lamp of automobile.
Background technology
Existing car light such 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 problem to be solved in the present invention provides 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 the housing, face shield is installed in 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 installed on the lens, speculum is near face shield, wiring board is placed with led light source in the lens back on the 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 the 70%--80%, and the polishing of speculum outer surface is aluminized.During work, the light that led light source sends is radiated on the 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 the speculum, two free form surfaces of speculum and face shield cooperate, 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, cooperate optical principle, size, the depth of imaging are realized controlled, thereby are applied among the 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, finish 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.
Apparatus of the present invention have the following advantages:
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.
