Abstract

The utility model relates to a full-reflection decorative light screen. A transparent material is embedded inside an opaque dark box provided with light source, and the light source is controlled properly to make the light ray of the light source have full reflection inside the material. The surface of the transparent material is etched with various patterns to destroy the conducting conditions of the light, and thus the light escapes from the patterns. Seen from the outside, the full-reflection decorative light screen has uniform light intensity distribution without a lamp. The utility model can be used for various advertisements, indications, decorations, artwork lighting tools or furniture, etc.

Description

Full reflecting decoration light screen

The utility model discloses a kind of total reflection and decoratees optical screen, belongs to advertisement, decoration, demonstration and illumination articles for use field.

Existing various decoration, advertisement, demonstration articles for use or light fixture etc., is no lack of its part attractive in appearance, practical, but all can see through the position that barrier is seen the inside light fixture, it is a kind of just as seeing that the scarce of " internal organ " shakes to cause for people's vision, therefore, the hope generation is a kind of it seems that from the outside light distribution is decorateed uniformly, advertisement article.

The utility model aims to provide a kind of total reflection that can remedy above-mentioned deficiency and decoratees optical screen, produces " seeing that light loses lamp ", the uniform fancy effect of light intensity.Can be widely used in aspects such as various advertisements, demonstration, decoration, handicraft, illumination articles for use or furniture.

Its design is as follows: this optical screen is combined by an opaque magazine 1, a transparent material 2 and light source 4, wherein, transparent material 2 embeds in magazine 1 certain one side, and can be fixed in its both sides with opaque shadow shield 3 in the part in it stretches into magazine, be shaped on crude according to certain decorative pattern on the material 2, light source 4 places in the magazine 1, should satisfy relational expression: L 〉=D between the height L of shadow shield 3 and transparent material 2 thickness D; When without shadow shield 3, then the thickness H of magazine 1 embedding and face should satisfy: H 〉=D.Magazine 1 usefulness cardboard, plank, iron plate or plastic plate class opaque material are made, and material 2 useable glass, lucite (phenolic resins) are made, and its crude surface can adopt mill flower, etch process to form.

It is to utilize light in the transparent material conducted inside that optical screen is decorateed in total reflection, and in the technology of needed local effusion light.Because total reflection can not be seen light in smooth transparent material surface, light source is arranged in the suitable magazine, produces the fancy effect of " seeing that light loses lamp ".Its derivation is as follows:

If transparent material is a glass, refractive index is 1.5, and air refraction is 1, and incidence angle and refraction angle are respectively α ₁And α ₂, law of refraction sin α is arranged ₁/ sin α ₂=n ₂/ n ₁

When light is injected and total reflection takes place, α ₂=90 °.

α ₁＝arc sin (n ₂)/(n ₁) （sinα ₂）＝arc sin（ 1/1.5 ·1）＝42°

At this moment, satisfy tg α=L/D

L＝tgα.D＝0.904D＝D

L 〉=D promptly satisfies total reflection and light does not spill so get.

After adopting said structure, can be used as uses such as billboard, label, direction board.When daytime during light intensity, the mill floral pattern still has advertising effects; It is more vivid eye-catching when light is weak.Also can be used as upholster, furniture and screen and decorate accessory etc., bright bright blazing.

Provide embodiment below in conjunction with accompanying drawing.

5 is fender bracket among the figure.Magazine 1 and shadow shield 3 usefulness planks are made, and thickness of glass is 5 millimeters, and its two sides etches pattern according to certain decorative pattern, destroy the conduction condition of light, then light is overflowed from pattern, and magazine 1 also is simultaneously the support that fluorescent lamp is installed, as for the Round table structure of Fig. 6, light source can be ensconced under the desktop.

Claims

1, optical screen is decorateed in a kind of total reflection, it is characterized in that: this optical screen is combined by opaque magazine 1, transparent material 2 and light source 4, wherein, material 2 embeds in magazine 1 certain one side, and can be fixed in its both sides with opaque shadow shield 3 in the part in it stretches into magazine, be shaped on crude according to certain decorative pattern on the material 2, light source 4 places in the magazine 1, should satisfy relational expression: L 〉=D between the height L of shadow shield 3 and transparent material 2 thickness D; When without shadow shield 3, then the thickness H of magazine 1 embedding and face should satisfy: H 〉=D.

2, according to the described optical screen of claim 1, it is characterized in that: magazine 1 usefulness cardboard, plank, iron plate or plastic plate class opaque material are made, material 2 useable glass, lucite (phenolic resins) are made, and its crude surface can adopt mill flower, etched technology to form.
