Description

Technical area

The The invention relates to a light guide with neon light effect, the one Ladder body combined with a ribbon, so that the light beam broken or reflected between the conductor body and the ribbon becomes.

State of the art

From thermoplastic materials such as polycarbonate, polyurethane, ethyl, PMA, or the like, the conductor body or the conductor core, which is usually enclosed by a protective layer or cladding, can be produced. This technique belongs to a known technique. Out US 4,422,719 is an "Optical distribution system including light guide" known, wherein the conductor body is provided with a sheath having a refractive index which is greater than that of the conductor body to enhance the light reflection, the Lichtleitstrecke in the conductor body to extend and a scattered light or To produce diffusion light. However, the envelope reduces the light brightness and the sharpness of light.

There between the inner surface of the envelope and the Outer surface of the conductor body only one There may be a destructive interference occur. When the light is a white light and the cladding has a small thickness, the blue light can be extinguished, so that a yellow light (complementary color for the Blue light enters the eyes. If the serving is a has big thickness, the green light can be deleted so that a light with the complementary color appears. Therefore, the light brightness is reduced by this destructive interference.

To solve this problem, the light guide is in 4,422,719 notched or mixed a photosensitive agent, a reflection powder or a metal oxide in the enclosure. As a result, the structure of the light guide is complicated.

Out US 6,169,836 B1 is an "optical transmission tube and method for making the same" US 7,433,565 B2 is a "side-scattering light guides" known. These optical fibers also each comprise a conductor body and a cladding, wherein the optical fiber has a refractive index which is greater than that of the cladding. The envelope also reduces light brightness and sharpness of light.

Around to increase the light brightness become organic polymer (such as silicone resin, polystyrene, metal oxide, carbonate or the like), Scattering or diffusion particles in the dissolved or polymerized conductor body mixed to increase the reflection and refraction effect. As a result, the manufacture of the light guide is ausschwert. The Reflection and refraction particles are incorporated in the material of the light guide mixed in and distributed by turning. Therefore, this light guide has with a length of 20 cm, a price of 70 to 80 NT $.

If When the light beam enters the light guide, it can pass through the or diffusion particles form shadows or create a diffraction. The diffraction is of the size and the wavelength of the light dependent (the greater the wavelength of light is, the stronger the diffraction). Therefore, the Selection of light limited.

Out US 7,433,565 B2 a further embodiment is shown, wherein between the conductor body and the envelope, an air layer or a medium layer is provided which has a refractive index which is smaller than that of the light guide. As a result, interference may occur because the light is reflected from the aerial view so that a bright band and dark band occur (alternately). The light entering the two eyes has two optical paths, ie the beam path of the light reflected by the cladding and the beam path of the light reflected by the optical waveguide. The light reflected from the light guide reaches the eye by a half-wave (phase difference), causing a destructive interference so that a dark band occurs. If there is no destructive interference, a bright band occurs. Ie. The close-fitting inner surface of the cladding and outer surface of the light guide generates the destructive interference so that the light brightness is reduced.

Ways to execute the invention

Like from the 1 and 2 can be seen, the invention comprises a conductor body and at least one ribbon, with the reference numbers 10 and 20 are designated. The ladder body 10 is made of transparent plastic, PMMA, polyurethane, glass, resin, thermoplastic material or the like (these materials are already described in the prior art and will not be described in detail here). In a preferred embodiment, the conductor body is transparent and flexible and has a good refraction and transmission (or light pipe). In the present embodiment, the conductor body 10 a round cross-section and has an axis line 11 and a scattering surface 12 , The ladder body 10 can also have a different geometric shape.

In the present embodiment, the ink ribbon 20 a ribbon with a color. The ribbon 10 is in the ladder body 10 embedded and runs in the axis line 11 of the ladder body 10 , The colorand 20 can also be plated with silver or the like to improve its reflectivity. In the present embodiment, the ink ribbon 20 a red color. The reflectance of the ribbon 20 is higher than that of the ladder body 10 , whereby a large part of the light in the conductor body 10 is reflected and only a small part of the light in the ribbon 20 occurs, whereby a neon light effect is achieved. The ribbon 20 is preferably made of material with a low degree of light absorption and a high transmittance, such as cross-chain polymer. This allows the light with a high efficiency through the conductor body 10 and the ribbon 20 be directed.

In one possible embodiment, the conductor body 10 and the ribbon 20 a cross sectional area ratio of 20: 1 to 90: 1. In 2 the cross-sectional area ratio is 60: 1. Therefore, the destructive interference or the bright band and dark band of the conductor body and the ink ribbon becomes 20 reduced to a minimum.

How out 3 it can be seen when the light S from one end 13 the light guide enters, it can be along the axis line 11 of the ladder body 10 be directed. A part of the light that matches the surface 12 and the ribbon 20 collides, gets into the ladder body 10 reflected or broken. If a ray of light, with the surface 12 (or the ribbon 20 ) collides and has an angle of incidence (angle between the light beam and the normal N) smaller than the critical angle (the smallest angle of incidence of total reflection), part of the light from the conductor body 10 be broken, causing the surface 12 a beautiful scattered light or diffused light is generated.

In the 3 and 4 become five beams of light 30 . 40 . 50 . 60 . 70 used. The light beam 30 enters the ladder body 10 and has an angle of incidence which is smaller than the critical angle, whereby a partial beam from the conductor body 10 is broken, leaving on the surface 12 a beautiful scattered light or diffused light is generated. The other part beam 32 gets on the ribbon 20 reflected, causing the ribbon 20 a stray light or diffusion light 33 is produced. A partial beam 34 is from the ribbon 20 on the surface 12 reflected. A small partial beam 35 enters the ribbon 20 in and in the direction of the normal N is broken. A partial beam 36 deviates from the normal N and gets out of the ribbon 20 on the surface 12 reflected while another sub-beam 37 in the ribbon 20 Reflected and then in the opposite direction from the ribbon 20 on the surface 12 is broken. A partial beam 38 of the sub-beam 37 will be in the ribbon 20 reflected.

How out 5 it can be seen when the light beam 40 in the ladder body 10 enters and has an angle of incidence which corresponds to the critical angle, the light beam passes 41 along the surface 12 , When the light beam 40 has an incident angle larger than the critical angle becomes the light beam 42 totally on the ribbon 20 reflected and then totally off the ribbon 20 reflected. It is also possible that the light beam 42 on the ribbon 20 a stray light or diffusion light 43 generated. A partial beam 44 enters the ribbon 20 and is broken in the direction of the normal N A partial beam 45 deviates from the normal, becomes out of the ribbon 20 on the surface 12 reflected and generated on the surface 12 a stray light or diffusion light 46 while a partial beam 47 in the ribbon 20 Reflected and then in the opposite direction from the ribbon 20 on the surface 12 is broken. A partial beam 48 of the sub-beam 47 will be in the ribbon 20 reflected.

6 shows an enlarged sectional view of the ribbon 20 , with the two sides of the ribbon 20 with the reference numbers 21 . 22 are designated. The Lict beam 50 enters the ribbon 20 and contain the light rays 51 . 52 . 53 , where the light beam 53 straight in the ribbon 20 runs.

The angle of incidence of the light beam 51 is smaller than the critical angle, creating a partial beam 51a deviates from the normal, from the ribbon 20 in the ladder body 10 is broken and on the ribbon 20 a stray light or diffusion light 51b generated. A partial beam 51c gets to the other side 22 of the ribbon 20 reflected. A partial beam 51d deviates from the normal N, is out of the ribbon 20 in the ladder body 10 broken and generated at the side 22 of the ribbon 20 a stray light or diffusion light 51e , A partial beam 51f will be in the ribbon 20 reflected and then from the ribbon 20 on the other side 21 Broken.

How to continue 6 it can be seen when the angle of incidence of the light beam 52 corresponds to the critical angle, runs the partial beam 52a along the surface or the side 21 of the ribbon 20 , if the angle of incidence of the light beam 52 is greater than the critical angle, the light beam 52b totally on the other side 22 of the ribbon 20 reflected.

As the ladder body 10 and the ribbon 20 a cross section area ratio of 20: 1 to 90: 1, run some parts of the light on the ribbon 20 over and is not covered by the ribbon 20 broken or reflected. In 7 the parts of this light are described with the reference numbers 80 . 90 are designated.

In 7 indicates the surface 12 of the ladder body two sides, with the reference numbers 14 . 15 are designated.

If the angle of incidence of the luminous flux 80 smaller is the critical angle, gives way to a partial steel 81 from the normal N and generated on the surface 12 a stray light or diffusion light 82 , A partial beam 83 runs on the ribbon 20 over and gets to the other side 15 of the ladder body 10 reflected. A partial beam 84 deviates from the normal N and becomes out of the ladder body 10 Broken. The part steel 83 can also be on the side 15 of the ladder body 10 a stray light or diffusion light 85 produce. A partial beam 86 gets into the ladder body 10 on the other side 14 reflected. When the angle of incidence of the light beam 90 larger is the critical angle, it runs on the ribbon 20 over and totally on the other side 15 of the ladder body 10 reflected.
